Project title: Building soils, communities, and profits with organic farming systems.

Demand for food grown using organic farming practices is growing rapidly - providing an opportunity for farmers in the Colca River Valley to increase the profitability and sustainability of their operations. Reasons for growth in the demand for organic farming includes perceptions around greater safety and nutritional quality of organically-grown crops, and fewer negative impacts of organic production systems on the environment due to factors that include lower pesticide use and application of natural rather than synthetic fertilizers. While evidence to support greater quality and safety of organic products is still controversial, many studies have demonstrated that organic practices do improve the health of soils and crops, and can increase profits for growers. Nevertheless, organic farmers often struggle to meet nutrient needs and control pests in these systems, which can limit crop yields and reduce capacity to meet food security goals. Moreover, soils and water within the Colca Valley may be contaminated with toxic heavy metals and metalloids such as arsenic and cadmium, which can exacerbate pest problems, lower crop yields, and negatively impact human health when these elements are taken up into edible plant tissues. Farmers in the Colca Valley need help in developing locally-adapted solutions to overcome these challenges and realize the benefits of organic systems.
The main objectives and outputs of the project are:
1) Increase adoption of organic farming practices by identifying specific barriers and conducting targeted training programs to help farmers overcome these barriers.
2) Increase crop productivity and food safety by identifying management practices that improve soil health and reduce the uptake of heavy metals into crops.
3) Further improve soil, crop, and human health by developing new, more effective ways to generate high-quality compost using a modified bokashi system.
4) Train local growers how to sustainably grow high-value warm season crops like tomato in earthen, greenhouse-like structures.
5) Establish the framework for a new graduate certificate in Agroecology and Sustainable Agriculture Development that will serve as the foundation for a graduate program in Agronomy at UNSA.
