Student team works with Colombian coffee growers


From Juana Muñoz Ucros and Marie Zwetsloot, Graduate Field of Horticulture, Bauerle Lab

Tucked away in the western arm of the mighty Colombian Andes lies the Cauca coffee-growing region. A stunning mixture of Afrocolombians, indigenous people and Spanish descendants fuses together around the culture of artisanal coffee growing.

Without machinery and with very few inputs — but enormous amounts of creativity — these farmers optimize yield in plots usually less than 2 acres. And even in the face of unpredictable weather, they manage to put children through college, pay off their loans, and experiment with organic farming.

In January, we led a student learning and research trip to Cauca as part of the Student Multidisciplinary Applied Research Team (SMART) program of the Cornell International Institute for Food, Agriculture and Development (CIIFAD). We made use of a previously established relationship with a cooperative of coffee farmers, Federación Campesina de Cauca (FCC), by Miguel Gomez and his graduate students in Applied Economics and Management.

Our group consisted of students from different disciplines and included Shanti Kumar and Jenny Lee from International Agriculture and Rural Development, Sam Bosco from Horticulture, Lizzy Sweitzer Cornell Institute of Public Affairs, and Whit Knickerbocker from Agronomy and Agribusiness Management.

During our visit, the team visited both organic and conventional coffee farms with the aim to better understand the economic, social and environmental challenges and opportunities that households from these different food production systems face. We interviewed the farmers about their management practices and took soil samples to evaluate pH and active carbon content of the soil. As an outcome, we left the FCC with a low-cost alternative to expensive lab soil tests that can inform them of soil health status and better direct their limited resources.

Full of pride and also of knowledge, the coffee producers showed the team around their farms and explained their philosophy and techniques. Even though communicating in Spanish wasn’t always easy, the producers were very patient in explaining their perspectives and sharing their experiences. Coffee farming is a tough living; stories of fluctuating coffee prices, health issues due to pesticide exposure and climate change were part of almost every conversation. The prospect of a peace deal finally put into action brings a smile to the farmer’s faces, but their reality is still one of political turmoil, government neglect, and ever present coffee leaf rust.

Besides the remarkable views of the endless mountains, one of the things that stood out was the hospitality and openness of the farmers. We were not allowed to leave the farm without having had at least one cup of sugary coffee, and a sampler of the tropical fruits grown by the family.

Seeing all of this with your own eyes makes you think hard about the coffee we drink every day.

American Vegetable Grower magazine turned to Thomas Bjorkman, associate professor in the Horticulture Section of the School of Intergrative Plant Science,  to answer questions about Cornell Soil Health Laboratory’s Comprehensive Assessment of Soil Health and the importance of knowing more than just your soil’s nutrient levels to produce healthy crops in two recent articles:

Water sensor moves from basic research to promising business

Cornell Chronicle [2017-02-06]:

A water sensor technology that began as basic research at Cornell is blooming into a business that fills a vital need for grape, nut, apple and other growers.

While current water sensing tools are expensive, inaccurate or labor intensive, the new sensor tells growers when their plants need irrigation with accurate, real-time readings at reasonable cost.

Much like a blood pressure gauge for humans, the sensor reads the water pressure inside the plant. When plants are thirsty, their water pressure is low, sometimes even negative. The sensor reads this pressure inside the plant to help growers ensure plant health and optimize water use in drought-stricken agricultural areas. Applying water at the right time can also greatly improve the quality of fruits, nuts and especially grapes for red wines.

In mid-2016, Cornell engineers and horticulturalists who developed the sensor launched FloraPulse, a startup aimed at commercializing the sensor and using it to provide agricultural services. The first target markets are grape and nut growers in California’s Central and Napa valleys.

Cornell Chronicle [2017-01-30]:

For the first time, 29 students in the International Agriculture in Developing Nations course had the opportunity to undertake a field study tour of Myanmar Jan. 1-16. It was the 49th class trip, through which students have visited Puerto Rico, Dominican Republic, Mexico, Costa Rica, Honduras and India.

“We decided to go to Myanmar this year because of the enormous changes underway in the country,” said Ronnie Coffman, international professor of plant breeding at Cornell and director of International Programs in the College of Agriculture and Life Sciences. “Agriculture plays an important part in this emerging economy, and this trip enabled students to see, firsthand, the challenges and opportunities faced by farmers.”

The group surveyed a range of agroecologies and production environments, traveling throughout the central dry zone, Inle Lake and Ayerwaddy Delta. Meetings with farmers gave students insight into various cultivation systems, from hydroponic tomato farming to small-scale melon production, while visits to agribusinesses highlighted the increasing trade and knowledge exchanges between Myanmar and its neighbors. The group also learned about alternative livelihoods, such as lotus weaving and lacquerware manufacturing, and engaged in Myanmar culture with visits to pagodas, temples and traditional puppet shows.

AHS, Garden-Based Learning Program collaborate on updated guide

The American Horticultural Society and the Cornell Garden-Based Learning Program have joined forces  to update and make available a free, web-based  tool to help educators and others launch garden programs for children, youth and families.

Sowing the Seeds of Success, also available as a printable publication, is designed to address “the increased interest in school and community garden projects and the troubling issues of food insecurity and nature deficit disorder,” says Fiona Doherty, educator enrichment specialist with the Cornell Garden-Based Learning Program, who led the update.

Originally published in 1999, the guide includes lessons, activities and program tools as well as links to additional resources to help start, sustain, expand and reflect on garden programs. “These can be used by teachers, parents and leaders of other community gardening programs to help empower young people with the skills to become the next generation of environmental stewards,” adds Doherty.

The guide is available in both mobile friendly and printer friendly versions.

2016 Dreer Award recipient Raquel Kallas (MS Horticulture ’16) is pursuing her interest in viticulture in Australia with the help of a familiar face to many: Vinay Pagay (PhD Horticulture ’14), now viticulture researcher and educator based at the Waite Campus of the University of Adelaide.

“His lab is on the cutting-edge of vineyard technologies that will allow us to better understand and manage the effects of climate change on vines and wine quality,” says Kallas. While a student at Cornell, Pagay helped develop a microfluidic water sensor within a fingertip-sized silicon chip that is a hundred times more sensitive than current devices.

Kallas’s collaborations with Pagay are funded through the Frederick Dreer Award. The Horticulture Section of the School of Integrative Plant Science offers this wonderful opportunity once a year that allows one or more students to spend 4 months to up to a year abroad pursuing horticulture interests. Deadline for application this cycle is March 6, 2017.

If you’d like to keep up with Kallas’s travels, visit her Dreer blog, Grapes of Raq.
