NEWS: Highlights of the AX Summer Research Fellowship

This summer, 8 undergraduate students from across the University of Vermont participated in the first year of the Agroecology Extension Summer Research Fellowship, a collaboration between UVM Extension, the Plant and Soil Science Department, and the ALC. 

We’re excited to share two opportunities to dig deeper into what the fellows were up to this summer around Vermont: a special feature on UVM Extension’s Across the Fence TV program and a CALS story, Agroecology in Action. Thanks to those who helped capture and share pieces of this program in its inaugural year. 

The fellowship is a part of USDA NIFA’s Research and Extension Experience for Undergraduates (REEU) program and will continue for the next 4 years. In future years, the workforce development grant will bring students both from UVM and institutions across the country to Vermont for an immersive summer research and extension experience in agroecology.

Sign up for online Course on Participatory Action Research (PAR) and transdisciplinary approaches to Agroecology

Interested in learning about how to apply participatory, trandsdiciplilary and action research in your work? Sign up for this online course taking place from September to December 2021.

Participatory, transdisciplinary and action research have become internationally recognized as pillars of knowledge production for agroecology and food sovereignty. These approaches are also complex and unorthodox in many contexts and requires a careful and intentional cultivation of a researcher’s commitments, skill and competencies. This course will help students to meet this challenge through a systematic engagement with theory, skills, methods and a critical reflexive self-examination of our role in the research processes.

INSTRUCTOR: Colin R. Anderson


CLASS MEETING TIMES AND LOCATION: Weekly zoom meetings on Tuesdays from 13:15 to 15:15 EST.

In this course, we will build a foundation for our learning by examining the ‘politics of knowledge’ or the ways that power and privilege shape science, academia, innovation and development. To this end, we will engage with critical theoretical traditions, such as feminism and decoloniality, to help students understand and challenge oppressive power relations in society as they are expressed in the knowledge systems that we are embedded within.

The course will explore different approaches to participatory and transdisciplinary research applied in different contexts.

If this sounds like challenging material, that’s because it is! But don’t stress too much, we’ll do our best to demystify and unpack these concepts together and to ground these ideas in relation to our own work, lives, and perspectives. We will also get practical and focus on the nuts and bolts of doing Participatory Action Research (PAR), which can be described as a process of research, education and action in which participants work together to understand and transform reality. It generally involves iterative cycles of inquiry by collectives of people seeking to address problems of common practical and political concern. We will shine a spotlight on several methods used within this tradition including, for example, participatory photography, popular education, theatre, indigenous approaches, deliberative methodologies, auto-ethnography and different forms of qualitative, quantitative and mixed methods inquiry.

The course will explore the value of ‘people’s knowledge’ and the notion of cognitive justice which demands, “It demands recognition of knowledges, not only as methods but as ways of life. This presupposes that knowledge is embedded in an ecology of  knowledges, where each knowledge has its place, its claim to a cosmology, its sense as a form of  life. In this sense knowledge is not something to be abstracted from a culture as a life form; it is connected to a livelihood, a life cycle, a lifestyle; it determines life chances.” (Visvanathan 2009)

We will look at PAR especially in the context of agroecology and examine how the integration of PAR and transdisciplinary approaches can serve to deepen our collective understanding of complex problems/issues. Students will learn how to apply a transdisciplinary PAR approach to topics in agrifood system studies and action. We will examine examples of agroecological PAR projects, to draw lessons learned and to find inspiration. Students will be asked to articulate and develop their own self-understanding of their praxis as a researcher.  In addition to asynchronous online learning, this course will include a synchronous 2-hour weekly online meeting via MS Teams that will involve a range of different interactive activities including discussions, workshops and guest speakers. Regular and active participation in these sessions is a core component of the course learning and assessment. Students will take on a rotating role in designing and facilitating a student-led component of the weekly meetings.

  • Deepened their understanding of how knowledge is situated, gendered, racialized, colonial and thus has contributed to social injustice and oppression;
  • Considered how these structures and power dynamics influence research processes;
  • Explored how PAR and transdisciplinary approaches can be applied in agroecology, including through the examination of inspirational case studies;
  • Learned about designing research that is both rigorous and provides meaningful contributions to the community/stakeholder(s) and the researcher(s);
  • Thought about their own positionality to situate themselves in the learning objectives above;
  • Developed strategies for critical self- and collective reflection and evaluation in participatory research processes and practice;
The course will include an exploration of the nuts and bolts of participatory and transdisciplinary research.

Amaya Carrasco-Torrontegui chosen for Graduate Student Award for Outstanding Research and Scholarship

Current Food Systems PhD student and ALC member Amaya Carrasco-Torrontegui was chosen for the Graduate Student Award for Outstanding MS Research and Scholarship in the Rubenstein School of Environment and Natural Resources, where she completed her MS in Leadership for Sustainability.

Community wellbeing was at the center of Amaya’s capstone, which also included a strong component of self awareness, leadership, and heart. Amaya developed and led an eight-session seminar in Spanish on sustainable food production in collaboration with the Missouri University Extension that was attended by 240 participants from nine different countries. The course was titled Agricultura Urbana Sostenible. She also offered support to people growing their own food with sustainable agriculture techniques in the United States, Ecuador, and other countries in Latin America; a particularly significant need during the COVID-19 pandemic when many were experiencing food shortages.

“Carrasco Torrontegui knows what it’s like to be a migrant; she has grandparents from Basque country in Spain, parents from Chile, and she was born in Ecuador.

“For me, it was very difficult to come to the U.S. because I didn’t have friends and my visa didn’t allow me to work or study,” Carrasco Torrontegui said. “And that was very hard.”

While walking around her neighborhood in St. Louis, Carrasco Torrontegui passed by a plot of land where people were growing plants.

She found out it was part of U City In Bloom, a nonprofit with more than 200 community gardens in University City. A volunteer at that garden happened to be from Ecuador, too; she became Carrasco Torrontegui’s first friend in the U.S. and introduced her to the world of urban agriculture.

“I discovered that was a passion for me — growing food, connecting with people, being in nature, learning from plants and insects,” Carrasco Torrontegui said.” From an article in NewsTribune.

Felicidades Amaya on this award and completion of this incredibly valuable project! Read the abstract of Amaya’s research and full paper: BE YOU: A JOURNEY TO FIND COURAGE. Amaya is currently involved in the Collaborative Crop Research Project, so stay tuned to see what she does next.

This exciting collaboration  will fund the development of an innovative undergraduate fellowship program in 2022 rooted in a transdisciplinary extension experience that will catalyze not only the dissemination of cutting-edge research ideas and technologies, but also demonstrate a healthy collaborative community for a thriving researcher and farmer partnership at a time when collaboration will be key to addressing increasingly complicated agricultural challenges.

Congratulations to all involved!

Looking for Moths Under the New Moon / Buscando mariposas bajo la luna nueva en El Yunque

By / Por: Luis Alexis Rodríguez-Cruz

This essay was written by Luis about his experiences assisting Aura M. Alonso-Rodríguez – both ALC members – with her research en El Yunque. This essay was originally published in Spanish in 80 grados and then translated by the author and published on Here’s more about Aura’s research

This essay was originally published in Spanish at 80 grados. It was translated by the author and published on

I was thinking of two things while walking: that my legs could not hold me anymore and that I wanted to see a coquí, Puerto Rico’s endemic frog. We had been within the green labyrinth of El Yunque, Puerto Rico’s tropical rainforest, for almost four hours. Although I wanted to look up and appreciate the plethora of stars, I kept my gaze down so that the flashlight on my head would light the way. Falling down on one of those paths, full of rocks and roots, while carrying a backpack full of scientific equipment, is not a pretty picture. There were times when I slipped, but still had not fallen. I was in the back of the line, walking slowly to see if I could spot a coquí, but without missing the pace of the team. “Look, Luis,” Aura said after a while. And there it was, quiet on a log, ready for the photo. After that, she asked us to turn off our flashlights.

Aura Alonso-Rodríguez is an ecologist. She studies human and climatic impacts on tropical ecosystems through insects. Two other people and I accompanied her on her once or two times-a-year pilgrimage to El Yunque, under the new moon. We were assisting her in her research, focused on understanding the impacts of Hurricane Maria on moth (nocturnal butterflies) communities. It is under the new moon that this type of sampling can be done effectively: the darkness reduces competition between the light from the trap and from the moon, thus attracting more moths.

The voices of the rainforest multiplied and amplified once we shut off the lights. To be immersed in the darkness of our rainforest and to listen to its sounds is not an opportunity that I am often given. In that moment, I finally looked up to the skies and appreciated the stars without fear of falling. As a drizzle began, we turned on the lights, and continued our walk back to the where we started.

We arrived around 6:30 P.M. to the El Verde field station, the research center of the University of Puerto Rico located in El Yunque. The objective was to go to the three spots that Aura selected, where we would place three traps with ultraviolet bulbs that would attract the moths. We carried three 25-pound batteries into the rainforest; each of us with a backpack full of equipment and several bottles of water and snack bars. It was almost 11 P.M. by the time we got back to the parking lot. The rain helped disguise the sweat and tiredness of our bodies.

That new-moon-weekend in July 2020 brought back memories of when I did research in the field, but it also reminded me of how complicated and complex it is, as many things are out of our control. Especially, when there is an ongoing pandemic. We returned to the house while listening to the symphony of our stomachs. And although we were tempted to open a few beers and socialize, we opted to go to sleep after eating, as we had to return to the forest around 5:00 A.M. When I saw Aura’s disappointment and frustration when finding the traps turned off the next morning, I knew we should have had at least one beer before going to sleep.

The coquí posing on a tree, and the trap turned on. Inside of the bucket there is a little flask with chloroform, and a forest of newspaper.

I arrived in Rio Grande, one of the municipalities where El Yunque is located, Friday afternoon. Aura and I met at a local supermarket to buy food for the weekend. The last time we saw each other was two months earlier, in Vermont, where we are studying. We stared at each other for a few seconds, and then hugged. Obviously, breaking pandemic protocols made us feel bad — even though we had been in isolation for a long time, preparing for that sampling weekend at El Yunque. It felt good to escape from the south of Puerto Rico, where I live. The drought, plus the Saharan dust, had the area all covered in brown and misty landscapes. These episodes of severe drought are becoming more frequent and intense in the Caribbean. Puerto Rico, like most islands in the region, is expected to see increasing temperatures due to climate change. Seeing so much green, while following Aura towards the house near the rainforest where we would be staying, was almost magical. “It is very dry here too, even if it doesn’t look like it” –she told me, as we got the equipment out of her car.

Aura has been collecting moths in El Yunque since the beginning of 2017. Little is known about them. In particular, their role in nocturnal pollination, which is important for the ecosystem, and for agricultural production. Aura told me that, “[all] butterflies belong to the order Lepidoptera, and more than 90% of them are nocturnal. The last study about them in Puerto Rico was done in 1998 (1); 1,045 species of butterflies were estimated, of which 26% are native to the archipelago.” The objective of her project was to know the degree of difference, if any, in moth communities (assemblages) in two forest areas in El Yunque: one dominated by Sierra Palm (Prestoea montana), and the other by Tabonuco trees (Dacroydes excelsa). There are 4 types of forests and various microclimates that make El Yunque a special place. To that we add its cultural and traditional significance, particularly the one that our Taino ancestors gave it. Unfortunately, human impacts, such as light pollution, solid waste mismanagement, and poorly planned constructions, together with natural impacts that are intensifying due to climate change (also human-driven), such as droughts and stronger storms, have increased the vulnerability of our national forest, producer of water, air and beauty. People like Aura seek to understand how, specifically, these impacts harm their biodiversity, in order to outline effective ways for conservation.

I underlined “was” in the paragraph above because Aura’s study now revolves around understanding how those assemblages changed with the impact of María, a 2017 category 4 hurricane that caused damage or death to 23-31 million trees in Puerto Rico [2]. “[Our study] is one way of better understanding the response and recovery of the forest to this impact.” Preliminary data from the study suggests that the assemblages were completely changed by the impact of the hurricane, regardless of forest type [3]. Nonetheless, after the hurricane, the number of individuals (abundance) and the number of species (richness) was higher in the area dominated by Tabonuco trees. “These trees are strong, they create underground connections between them, unlike Sierra Palms that do not provide good shelter due.” Therefore, given that the impacts will continue to occur, if we want to safeguard the biodiversity of the forest, it is important to conserve those areas dominated by Tabonuco, most of which are remnants of mature forest. Meaning that these areas have not been affected by human disturbances. Aura is confident that future samplings will shed more light on that preliminary conclusion.

The figure on the left shows the assemblages in Sierra Palm and Tabonuco before and after María. Each point represents the species composition at a different sampling site. By agglomerating the points in the different ovals, the statistics show that the assemblages changed due to the impact of the hurricane in both types of forest. The figure on the right, divided in two, shows richness and abundance. In both, the boxes on the left side show that the richness and abundance of both areas was similar before the hurricane. But those on the right side show that assemblages in the Tabonuco forest had more richness and abundance after the hurricane.

As we walked under the subtle light of dawn to where we had left the traps, Aura pointed out areas and described how they were like before the hurricane. Frankly, everything looked the same to me. It was remarkable how embedded she was in the landscape and the connection she had with the forest. I told the team that if they were following me, we would have already gotten lost and would never find where we left the traps. “I grew up in the forest,” Aura said. And just as she had seen El Yunque transform, she also saw how the mountains of Carraízo, where she was raised, transformed throughout her childhood. Witnessing the change of the landscape catalyzed questions that she would later answer through her scientific work. “What do you feel?”, I asked her when we got to the first spot and saw the light off. Although there was a hint of anger and frustration, Aura took a deep breath and began to tell us the possible causes. She had checked the voltage of the batteries and tested them before the weekend. But as she said, it was not in her control that they got damaged. Sometimes one wastes so much energy in pondering over something one does not control. And now, whenever something similar to the “battery situation” happens to me, I think about how Aura responded to it.

We proceeded to remove the trap — we noticed that several moths were caught, but not the number that she expected. Yes, seeing their corpses raised uncomfortable questions in me. But their life cycle is very short and sampling once or twice a year does not harm the population―I said to myself. When collecting all the equipment, Aura took out a densiometer and together with the other colleague measured the canopy to see how much light enters the area. By comparing the canopy cover data that Aura took before and after Hurricane Maria, she can determine how much the forest has recovered since the hurricane. Then we walked up the mountain to find the second trap off. The same happened with the third. And what do you do when an experiment goes wrong in El Yunque? Well, you go for a dip in a swimming hole.

Above, Aura is setting the trap. Below, holding the densiometer, and separating the collected specimens.

While floating in the river, Aura went over different options on how to deal with the setback. She would soon have to return to Vermont, and coinciding with the new moon in Puerto Rico is not an easy thing. So, she had to re-sample to not miss the opportunity. The next day, when I had to go back to the hot south, we returned with charged batteries and set up a camera to see how long the light bulbs lasted. Before I left, I went with her to the laboratory to help sort the samples we collected the previous night. We were classifying all the moths by morphospecies, that is, by how they resemble each other. “That’s why I like insects, you have to learn how to see the details” -she said, while she explained to me how difficult it was to determine the real species, particularly that of the smallest ones.

I wanted to stay longer to help with the resampling, but responsibilities in the south required attention. As I was driving home along the old highway, it was clear how the green was turning brown. During that week, I could not get what happened in El Yunque out of my mind, plus my flat feet kept reminding me of how much we walked. Neither could I shake off that moment of silence and stillness when we turned off the lights. At the end of the week, Aura told me that they managed to acquire new batteries and that she decided to repeat the sampling the following month. Putting the camera served to check how long the bulbs were on and thus be able to adjust their results.

There are three new moons this summer of 2021, so maybe I’ll be an assistant to my ecologist friend again. Meanwhile, I hope to educate myself more about Tabonucos, about where they are in Puerto Rico, and on what we can do as a society to protect them. As the song of Francisco Roque Muñoz says, “Un jacho de tabonuco, tengo yo para alumbrarme” (A piece of Tabonuco, I have to light up the way).

Buscando mariposas bajo la luna nueva en El Yunque – This essay was published originally in 80 grados (Puerto Rico) in March 12, 2021.

Iba caminando y pensando dos cosas: en que ya no aguantaba las piernas y en que quería ver un coquí. Llevábamos casi cuatro horas bosque adentro en El Yunque. Aunque quería mirar hacia arriba y apreciar el revolú de estrellas, tenía la mirada hacia abajo para que la linterna en mi cabeza iluminara el camino. Caerse en una vereda de esas, llenas de piedras y raíces, mientras se carga un bulto lleno de instrumentos científicos, no debe ser bonito. Hubo ocasiones en que resbalé, pero aún no me caía. Yo iba atrás en la fila, caminando lento para ver si lograba ver un coquí, pero sin perder el paso del equipo. “Mira, Luis”—dijo Aura al ratito. Y allí estaba, tranquilito en un tronco, listo para la foto. Luego de eso, ella nos pidió que apagáramos las linternas.

Aura Alonso Rodríguez es ecóloga. Estudia los impactos humanos y climáticos en ecosistemas tropicales a través de los insectos. Otras dos personas y yo la acompañamos en su peregrinación a El Yunque bajo la luna nueva para asistirle en su investigación, enfocada en entender los impactos del huracán María en las comunidades de mariposas nocturnas. Es bajo la luna nueva cuando este tipo de muestreo se puede hacer de manera efectiva: esa fase oscura ayuda a que la luz de la trampa no compita con la de la luna y así pueda atraer a las mariposas.

Los sonidos se intensificaron tan pronto apagamos las luces. No hablamos. Escuchar al bosque tropical más importante de Puerto Rico no es algo que se me da mucho. En ese momento pude mirar hacia arriba y apreciar el revolú de estrellas. Al comenzar una llovizna, prendimos las luces y continuamos.

Llegamos alrededor de las 630 P.M. a la estación El Verde, centro investigativo de la IUPI ubicado en El Yunque, para ir a los tres spots que seleccionó Aura, donde colocaríamos las tres trampas con bombillas ultravioletas que atraerían a las mariposas. Cargamos tres baterías de 25 libras cada una; cada quien con una mochila llena de equipo y varias botellas de agua y barritas para merendar. Ya eran casi las 11 de la noche cuando regresamos al estacionamiento. La lluvia ayudó a disimular el sudor.

Ese fin de semana de luna nueva en julio 2020 me trajo recuerdos de cuando hacía investigaciones en el campo, pero también me hizo recordar lo complicado y complejo que es, pues muchas cosas no están bajo nuestro control. Especialmente, cuando hay una pandemia en curso. Nos fuimos escuchando la sinfonía de nuestros estómagos. Y aunque nos tentaba abrir cervezas y socializar, optamos por ir a dormir después de comer, pues teníamos que volver al bosque alrededor de las 5:00 A.M. Al ver las bombillas de las trampas apagadas cuando volvimos al bosque y la cara de decepción y frustración de Aura, supe que debimos habernos bebido por lo menos una cerveza antes de dormir.

El coquí posando y la trampa recién prendida. Adentro hay un envase con cloroformo y un bosque de papel periódico.

Yo llegué a Río Grande viernes por la tarde. Me encontré con Aura en un supermercado del área. La última vez que nos vimos fue dos meses antes, en Vermont, donde cursamos estudios. Nos quedamos mirándonos unos segundos y nos abrazamos. Obviamente, nos hizo sentir mal romper los protocolos pandémicos—aunque llevábamos mucho tiempo en aislamiento, preparándonos para ese weekend de muestreo en El Yunque. Me hizo bien escapar del sur. La sequía, más el polvo del Sahara, tenían la zona toda arropada de marrones y paisajes brumosos. Ver tanto verde, mientras seguía a Aura hacia la casa dónde nos quedaríamos, fue casi mágico. “No te creas, esto está bien seco aquí también” –me dijo, mientras bajábamos el equipo de su carro.

Aura lleva desde principios del 2017 recolectando muestras de mariposas nocturnas, de las cuales no se sabe mucho. Particularmente, su rol en la polinización nocturna, lo cual es importante, no solo para el ecosistema, sino incluso para la producción agrícola. “Las mariposas (todas) son del orden Lepidoptera y más del 90% de ellas son nocturnas. El último estudio en Puerto Rico fue en el 1998 [1]; se estimaron 1,045 especies de mariposas. El 26% son nativas del archipiélago.” ―me contaba Aura. El objetivo de su proyecto actual era conocer el grado de diferencia, si alguna, en las comunidades de mariposas nocturnas (ensamblajes) en dos áreas del bosque: una dominada por palma de sierra (Prestoea montana) y otra por tabonuco (Dacroydes excelsa).

En El Yunque hay 4 tipos de bosques y varios microclimas que hacen de él un lugar especial. A eso le añadimos su significado cultural y tradicional, particularmente la que le dio nuestros ancestros Taínos. Lamentablemente, los impactos humanos por contaminación lumínica, desechos sólidos y construcciones mal planificadas, en conjunto con impactos naturales que van intensificándose por el cambio climático (también causa humana), como las sequías y tormentas, han hecho que la vulnerabilidad de nuestro bosque nacional, productor de agua, aire y belleza, vaya en aumento. Personas como Aura, buscan entender cómo, específicamente, esos impactos perjudican su biodiversidad para entonces delinear maneras efectivas para la conservación.

Arriba subrayé “era” porque el estudio de Aura giró en torno a comprender cómo esos ensamblajes cambiaron con el impacto de María, huracán que causó daños o muerte de 23-31 millones de árboles en Puerto Rico [2]. “Es una manera de entender mejor la respuesta y recuperación del bosque”. Datos preliminares [3] de su estudio muestran que los ensamblajes cambiaron por completo por el impacto del huracán indistintamente del área. Sin embargo, después del huracán, el número de individuos (abundancia) y la cantidad de especies (riqueza) fue mayor en la zona dominada por tabonuco. “Esos árboles son fuertes, crean conexiones entre ellos bajo la tierra, a diferencia de las palmas de sierra que pierden las pencas y quizás no proveen buen refugio”. Por lo tanto, dado a que los impactos seguirán ocurriendo, si queremos salvaguardar la biodiversidad del bosque, es importante conservar esas zonas dominadas por tabonuco. Aura confía en que los próximos muestreos arrojarán mayor claridad a esa conclusión preliminar.

La figura de la izquierda muestra los ensamblajes en palma de sierra y tabonuco antes y después de María. Cada punto representa la composición de especies en un sitio de muestreo diferente. Al aglomerarse los puntos en los distintos óvalos, la estadística muestra que los ensamblajes cambiaron por el impacto del huracán en ambos tipos de bosque. La figura de la derecha, dividida en dos, muestra riqueza (“richness”) y abundancia (“abundance”). En ambas, las cajitas del lado izquierdo muestran que la riqueza y abundancia de ambas áreas era similar antes del huracán. Pero las del lado derecho muestran que en el bosque de tabonuco se encontró mayor riqueza y abundancia de mariposas nocturnas después del huracán.

Aura señalaba áreas y describía cómo eran antes del huracán, mientras caminábamos hacia donde habíamos dejado las trampas. Francamente, para mí todo se veía igual. Era notable cuán inmersa estaba ella en el paisaje y su conexión con el bosque. Y más cuando no había amanecido del todo. Yo le comentaba que, si me estuvieran siguiendo a mí, ya nos hubiéramos perdido y nunca encontraríamos dónde dejamos las trampas. “Yo me crie en el bosque” ―me decía Aura. Y así cómo había visto a El Yunque transformarse, también vio cómo la montaña de Carraízo, dónde se crio, fue transformándose a través de su infancia. De ahí comenzaron preguntas que luego contestaría a través de su trabajo científico. ¿Qué sientes? –le pregunté cuando llegamos al primer spot y vimos la luz apagada. Aunque hubo una pizca de enojo y frustración, Aura respiró profundo y comenzó a contarnos las posibles causas. Ella había verificado el voltaje de las baterías y las había probado. Pero como ella dijo, el que se dañasen no estaba en su control. A veces uno se vuelve loco ponderando sobre algo que no controla. Y ahora, cada vez que pasa algo similar al papelón de las baterías, pienso en cómo Aura respondió a la situación. Procedimos a quitar la trampa—notamos que se atraparon varias mariposas, pero no la cantidad que se esperaba. Sí, me dio cosita verlas muertas. Pero su ciclo de vida es bien corto y muestrear una o dos veces al año no perjudica a la población. Al recoger todo el equipo, Aura sacó un densiómetro y junto a la otra compañera se midió la cobertura de dosel, para conocer cuánta luz entra a la zona. Comparando los datos de cobertura de dosel que Aura tomó antes y después del huracán María, ella puede determinar cuánto se ha recuperado el bosque desde María. Luego, nos fuimos jalda arriba para encontrar el segundo spot apagado. Pasó lo mismo con el tercero. ¿Y qué se hace cuándo un experimento sale mal? Pues, nos fuimos a nadar un rato a una charca del área.

Arriba Aura está montando la trampa. Abajo, se muestra el densiómetro y a Aura separando los especímenes recolectados.

Mientras flotaba en el río, Aura compartía distintas opciones para lidiar con la situación. Pronto tendría que volver a Vermont, y coincidir en Puerto Rico con la luna nueva no es cosa fácil. Por lo que había que volver a muestrear para no perder la oportunidad. Al otro día, cuando yo tenía que volver al sur caluroso, regresamos con las baterías cargadas y colocamos una cámara para saber cuánto tiempo duraba la bombilla prendida. Antes de irme, fui con ella al laboratorio para ayudarla a clasificar las muestras. Ese día también aprendí que decirles “polillas” no es lo mejor. Alevilla o mariposa nocturna. A cada ratito Aura me decía que estaba poniendo distintas mariposas juntas. Las estábamos clasificando por morfoespecie, o sea, por cómo se parecen entre sí. “Por eso me gustan los insectos, hay que saber ver los detalles” -decía, mientras me explicaba lo difícil que era determinar la especie real, particularmente de las más pequeñitas.

Yo tenía ganas de quedarme más días para retomar muestras, pero las responsabilidades en el sur requerían atención. Mientras guiaba por Fajardo, camino a Juana Díaz por la carretera vieja, se notaba bien claro cómo el verde se tornaba marrón. Durante esa semana, no me podía quitar de la mente lo ocurrido en El Yunque, más mis pies planos no paraban de recordarme todo lo que caminamos. Tampoco me podía desprender de ese momento de silencio y quietud cuando apagamos las luces. Al final de la semana, Aura me contó que lograron adquirir nuevas baterías y que decidió repetir el muestreo el mes siguiente. Poner la cámara sirvió para conocer cuánto tiempo estuvieron las bombillas prendidas y poder así ajustar sus resultados.

Hay tres lunas nuevas este verano 2021, quizás volveré a ser asistente de mi amiga ecóloga. Mientras tanto, conviene educarnos sobre los tabonucos, sobre dónde están y cómo conservarlos. Como dice la canción, “Un jacho de tabonuco, yo tengo para alumbrarme”.

ALC members Scott Lewins, Vic Izzo, Janica Anderzén, and Alejandra Gúzman Luna have received funding to advance their Participatory Action Research (PAR) projects both locally and internationally. We’re so grateful for the support and excited to see these projects through!

The Vermont Vegetable and Berry Growers Association and the New England Vegetable and Berry Growers Association have recently made donations to the Vermont Entomology and Participatory Action Research Team (VEPART), led by Scott Lewins and Vic Izzo, in support of their research and outreach efforts within the region. This great partnership between VEPART and two key grower groups is part of VEPART’s ongoing Participatory Action Research on appropriate IPM tactics for northeastern organic growers, and ultimately a more sustainable approach to pest management.

This generous grower support has helped launch the Agroecology Extension Summer Research Fellowship, an experiential learning experience focused on the development of adaptable research, leadership, and outreach skills. The goals of this exciting new initiative include training the next generation of extension researchers, and contributing to new and ongoing Extension projects dedicated to UVM’s Land Grant mission.

From the Gund Institute for the Environment’s website: Gund Graduate Fellow Janica Anderzén (CALS) will study the ecological, economic, and social importance of bees for coffee farmers in Chiapas, Mexico. Native and managed bees help shade-coffee farmers ecologically by pollinating coffee and food crops. Farmers who manage honeybees are less financially dependent on coffee, increasing their resilience. Her results will inform farmer and community education programs and dialogues with local governments regarding harmful pesticides.

NEWS: ALC contributes chapter to Urban Agroecology book

ALC co-director Martha Caswell and other members of the ALC contributed a chapter to a new book titled Urban Agroecology, Interdisciplinary Research and Future Directions. The chapter discusses an ongoing participatory action research (PAR) project with urban and peri-urban agroecology project partners in Burlington, Vermont. For years, the ALC has been building a relationship and working with  the Vermont Community Garden Network, the Intervale Center, New Farms for New Americans, and the Catamount Farm. Components of this PAR process have resulted in participatory mapping and inventorying of agroecological practices with the Intervale Center, student design projects facilitated through PSS courses taught by Stephanie Hurley and Annie White, and upcoming collaborations for a summer research fellowship with VEPART to tackle pest management challenges.

The research in this chapter brings together agroecological principles, landscape design, and cultural ecosystem services in a transdisciplinary, PAR approach to assessing urban agroecology in Burlington. While Vermont is a predominantly rural state, this chapter explores the growing field of urban agroecology through urban and peri-urban farms and gardens in and around Burlington. Urban agroecology utilizes the frameworks and approaches of agroecology and applies them to urban contexts. As demonstrated in existing research, urban agrifood systems fill a multifunctional role in urban areas and can contribute to addressing issues such as food insecurity, public health crises, and poverty. As such, there is great potential for the application of agroecology in urban agrifood systems, and in further exploring and amplifying the benefits.

While the ALC’s work with these partners is ongoing, the value and importance of vibrant local food systems has been highlighted in the current COVID-19 pandemic and resulting food crisis. Through our PAR process, we look forward to continuing to facilitate conversations and connections within Burlington that center around agroecology and its potential within the urban and peri-urban context.  As articulated in the chapter, “Ideally, by reinforcing its presence and relevance, agroecology can become a unifying catalyst for broad food system transformation in Burlington” (p 316).

NEWS: ALC Co-Director Ernesto Méndez selected for VP of Research fellowship

The ALC is excited to share the news that ALC Co-director Ernesto Méndez has been selected as the inaugural Office of the Vice President for Research (OVPR) Fellow at UVM.  This competitive fellowship provides institutional support for the institutionalization of  the ALC as a University of Vermont institute. Tentatively named the International Agroecology and Food Systems Institute, this initiative will integrate research, education, and outreach to better understand and support food systems that are ecologically sound and socially just. This new unit will have three primary areas of focus, 1) Agroecological performance, 2) Agroecology, food sovereignty and justice, and 3) Innovative pedagogy for agroecology. 

This fellowship comes at a critical time as multiple crises nationally and globally have worsened and revealed issues in our food and agricultural systems. The COVID-19 pandemic has shown our high level of vulnerability to industrialized agricultural and food systems. Supply chains got broken, healthy and nutritious food became inaccessible, and those who are on the front lines of food production were forced to take on enormous risk. Alternatively, ecologically sound and socially just agrifood systems, which rely on local food production at small and medium-scale production, have emerged as a more stable and sustainable alternative that can withstand multiple crises globally. The transformation of the ALC, which started as a research group, will create an opportunity to address many of these issues through agroecological frameworks, deepening the capacity and learning of agroecology and food systems scholars, and students and community partners at UVM and beyond.

BLOG: Exploring the newly launched Vermont Agrarian Commons at Bread and Butter Farm

By: Nell Carpenter and Martha Caswell, with input from Megan Browning, Vermont Agrarian Commons

In the spring of 2020, Bread and Butter Farm, a farm partner of the ALC, became the founding farm of the Vermont Agrarian Commons, one of a collection of ten Agrarian Commons nationwide. The Agrarian Commons is a model for land access that challenges notions of land ownership established in the U.S. by European colonizers, and seeks to redefine land access for farmers, with particular attention toward the next generation of farmers. By reconsidering relationships to land, this movement provides new options in reaction to the U.S. Agricultural Crisis, and its many ecological, sociocultural, and economic impacts. Though there is a global movement toward agricultural commons as a viable, and desirable model – there are context-specific details that are particular to each locale. 

Below, we will dig deeper into the Bread and Butter example to better understand how this works, but to start let’s set the stage for its relevance. The Agrarian Commons is a model inspired by centuries of thought, practice, and community. This model recognizes that the current model of land ownership over the land currently known as the U.S. was a foothold in colonizing the land, dictated by capitalist and white supremacist frameworks of leadership and governance. The Agrarian Commons model envisions a return to a relationship with the land that more closely resembles the reciprocal, stewardship of land that has been practiced through intergenerational management by BIPOC and peasant communities around the world.  Read more about who and what has inspired the Agrarian Commons here, and hear current stakeholder perspectives here

As we know, land is a limited and expensive resource, which can mean that farmers who are able to access land are perpetually working to lessen their debt, but aren’t ever able to escape that burden. This can result in farmers spending the majority of their careers engaging in unsustainable agricultural practices to chip away at mortgage debt that only gets passed to the next farmers of that land. Many tools and structures such as conservation easements exist to help lessen these costs, however, land access for those who want it remains a primary challenge, especially for BIPOC community members who have been excluded by long histories of racist and exclusionary policies.

The commons is a strategy for increasing access to land and freeing up financial resources for regenerative agricultural practices by making land available at a lower price and providing a structure for land to be held in community, rather than individually owned. This lower price is possible because the land is acquired  by a nonprofit legal entity (501c2) – in this case the Vermont Agrarian Commons – through fundraising or land donation. The Commons then provides a 99 year ground lease of the  land to a farm business – in this case Bread and Butter Farm. The Agrarian Commons are governed locally by a board composed on ⅓ leaseholding farmers, ⅓ community stakeholders, and ⅓ Agrarian Trust staff, and exist in partnership with Agrarian Trust (501c3). The Agrarian Commons model and lease structure is governed by bylaws, such that each farm business operating in the commons adheres to a level of social and ecological sustainability in their operations with a focus on agriculture in community. The land in the commons is, thus, decommodified, out of the real-estate market, and considered a member of the commons alongside the business(es) it hosts.  While Bread and Butter is the founding farm for the Vermont Agrarian Commons, there will be opportunities for the Commons to grow with additional land and farms over time. Other Agrarian Commons exist around the country, in various states from California to Virginia. Explore them all here.

Beyond breaking the cycle of unsustainable land ownership and inequitable access and tenure to land, the Agrarian Commons can be a step towards food sovereignty, particularly for BIPOC and immigrant communities. In Central Maine, the Little Jubba Central Maine Agrarian Commons was just established in association with the Somali Bantu Community Association (SBCA). This land will expand their existing Liberation Farms land for SBCA farmers, an important foothold of food access and cultural vibrancy for the Somali Bantu Community. The Little Jubba Agrarian Commons and others will be able to ensure that the land remains in their possession for at least the next 99 years. In tracing the current and historic stealing of land, genocide, and racist land policy, this is a significant step in creating opportunities for BIPOC farmers and communities to reclaim land. And, in the event that an Agrarian Commons entity dissolves, the “bylaws ensure that all assets will transfer to Indigenous communities and communities of color as one small way to move against the perpetuation of white-led nonprofit ownership of land” ( 

In late October, the ALC welcomed Megan Browning from the Agrarian Trust/VT Agrarian Commons for a discussion about the commons with our Community of Practice. In just a little over an hour, we learned about the overarching vision and then dug into the legal details. After lots of questions and discussion, it’s clear that this movement is on its way towards very concrete impact in the United States.

Megan is working with Corie Pierce and Brandon Bless of Bread and Butter Farm (BBF), as well as additional board members, to establish the Vermont Agrarian Commons through the acquisition of land. BBF is a collaborative working landscape that actively honors its land, animals, community members, soil, plants and history. The original parcel of land farmed by  BBF was around 140 acres of extremely depleted land. In 2018, BBF entered into a three year lease for eventual ownership of 375 acres of land that would have otherwise sold to developers. The negotiation involved significant contributions by the Vermont Land Trust, town of South Burlington, town of Shelburne, and Dirt Capital Partners, as well as the Vermont Housing and Conservation Board, and the Natural Resources Conservation Service. Currently, BBF  manages over 600 acres of land through ownership and lease, which is the land to become the Agrarian Commons with the support of the partners named above,  local community members and, Agrarian Trust. 

Corie wrote a piece about this experience that you can read here, but here’s a preview to help you understand what this means to Corie and others at BBF.

“We absolutely love this model because it does so many things!!

  1. Most importantly, it helps to guarantee a high standard of managing land forever by excellent farmers. 
  2. It means that this land WILL be farmed forever! It can never be a gentleman farm that is just mowed each year and owned by an individual who chooses to work elsewhere and not farm but have the luxury of their own 500 acres for themselves.
  3. Bread & Butter Farm is relieved of our mortgages and allows us to make investments in the farm business for the future for the people who work here and for the needed infrastructure.
  4. We commit this land to a commons model where there will be 17 miles of beautiful trails that weave through the 500 acres for the community to enjoy (think Shelburne Farm walking trails in the southeast quadrant of South Burlington!), and…
  5. This will become a model for future farms in Vermont and for the country, which is EXACTLY what we need!!  More viable models so that more amazing land steward/farmers are incentivized to farm and are ABLE to farm so that we can provide nourishing food for our community and simultaneously building soil and health of the land. And many more amazing reasons.”

NEWS: ALC team contributes to important paper discussing ‘The evolving landscape of agroecological research’

A paper recently accepted in the journal Agroecology and Sustainable Food Systems charts the evolving landscape of agroecological research using innovative bibliometric and network analysis. Led by Dr. Rachel Mason, a PSS alum who now works at the National Socio-Environmental Synthesis Center, the article analyzed the evolution of themes in agroecology research between 1982 and 2018. The author team, which included ALC Co-director Ernesto Méndez, ALC research associates Gabriela Bucini and Scott Merrill, and ALC doctoral candidates Alissa White and Janica Anderzén, examined the evolution of agroecological research using research papers from the Web of Science. This manuscript is an important contribution about the evolution and growth of the field of agroecology as shown by trends in scientific publications. Moreover, the content of the scientific papers signals that agroecological science has been increasingly engaging with social movements and taking a wider food systems perspective.

The figures below summarize and characterize agroecology in academic research over time, demonstrating an increase in work focusing on food sovereignty, food justice and social movements (you can click on each figure to enlarge). The paper uses citation-based networks to identify discrete areas of research within agroecology, and shows that many of those areas build on knowledge from social science disciplines. We share the abstract and link to the article after the figures.


It has been widely argued that agroecological science, which originally developed as the application of ecological principles to agricultural systems, should engage with the social and political issues that affect production agriculture, and incorporate knowledge from a variety of sources.  In this paper we use techniques from network science and bibliometrics to evaluate the degree to which this transformation has taken place. By creating networks based on over 3,000 agroecology papers and the roughly 160,000 references they cite, we distinguish the sub-fields (“research fronts”) that made up agroecology in three time intervals: 1982 – 2004, 2005 – 2013, and 2014 – 2018. We also identify the main disciplines from which the research fronts in 2014 – 2018 drew their supporting knowledge. We suggest that, very broadly, themes in agroecological research include: Ecosystem services; (agro)biodiversity; approaches to agricultural intensification; tropical agroecosystems (particularly coffee); pest and weed management; organic agriculture; cropping systems; system transitions, modeling and design; climate change adaptation; food sovereignty; education; and the nature and purpose of agroecology itself. Some research fronts mainly cite papers in natural science fields such as ecology, environmental science, agriculture, and entomology. However, others draw upon work in social science areas including development studies, environmental studies, and anthropology. The analysis presented in this paper demonstrates that agroecology has indeed evolved to possess many of the characteristics of an “ecology of [the entire] food system”. We anticipate that this work will also be of use to those wishing to gain an overview of the field or identify key papers, knowledge gaps and potential collaborations.
