Combining Vegetables and Livestock in Cambodian Farming

About the Horticulture Innovation Lab

Led by 新澳门六合彩内幕信息 Davis and funded by the U.S. Agency for International Development, the is part of the U.S. government鈥檚 global hunger and food security initiative called Feed the Future.  Researchers from throughout the United States participate in lab projects in Asia, Africa and Central America, to help farmers better grow nutritious fruits and vegetables.

In addition to this , the program has two other research projects in Cambodia 鈥 one looking at and one led by 新澳门六合彩内幕信息 Davis researchers focused on .

New research supported by the at 新澳门六合彩内幕信息 Davis aims to help farmers in Cambodia better integrate growing vegetables, raising livestock and maintaining healthy soil 鈥 all in the same place.

鈥淏y understanding the interactions between horticulture and livestock systems, we can help farmers make better use of agricultural inputs such as fertilizer and labor, which will help improve a farmer鈥檚 bottom line,鈥 says , which is funded by the U.S. Agency for International Development.

鈥淪ystems thinking鈥 is critical to making a real-world impact in global food security, according to , project leader and assistant professor at Kansas State University. It鈥檚 also required to understand . 

鈥淭oo often overlooked is that systems piece, the very fact that these things 鈥 crops and livestock, soil health and human health 鈥 play together. It鈥檚 not always enough to study a single piece of the pie,鈥 Vipham says.

Combining conservation agriculture with swine and cattle

As part of the U.S. government鈥檚 global hunger and food security initiative, the Horticulture Innovation Lab already has research in Cambodia helping farmers better grow vegetables using . These improve soil health by combining continuous mulch, reduced tillage and diverse crop rotation.

鈥淲hen we visited the farms our researchers have been working with in Cambodia, they already had animals there. Figuring out how to best utilize their livestock is just smart,鈥 McGuire says.

Because the Cambodians were sensitive to using pesticides and other synthetic supplements, they were interested in substituting manure and other livestock byproducts, she reports.

Manure vs. mulch

With farmers near 鈥 the city closest to Cambodia鈥檚 famous 鈥 the team鈥檚 research will focus on integrating pigs with crops. One question the team will investigate is whether the parts of a vegetable plant that don鈥檛 become human food might be used to better feed pigs instead of being used as mulch.

The Horticulture Innovation Lab team will investigate whether pig manure might take the place of that mulch and the various trade-offs in using manure vs. mulch.

Farther west, near the city of Battambang, farmers are more interested in cattle. Vipham explained that in this region cattle are often valued as a type of income safety net. If a farmer suddenly needs some money, then the family can sell their cow. Research trials will likely focus on ways to maintain a cow鈥檚 physical condition (and potentially its selling price) with crops grown for livestock feed, alongside the farmers鈥 usual vegetable crops for sale and human consumption.

Advancing science while building local capacity

The American team will be working with Cambodian scientists from the and the . The international group met recently in Cambodia to explore research sites and make plans to move forward. Vipham is encouraged to see the scientists come together as a team.

鈥淚t鈥檚 one thing to make plans and write a grant proposal,鈥 Vipham says. 鈥淚t鈥檚 a totally different thing when you have your livestock scientists and horticulturalists and soil scientists on the ground, looking at the same thing, and you can see their wheels start to turn.鈥

One of the Cambodian researchers, Lyda Hok, is director of the , which includes five new 鈥渢echnology parks鈥 where the team鈥檚 research will take place.

鈥淲ith the five technology parks, we will be able to share this useful information and recommendations to more farmers throughout the country,鈥 Hok says.

鈥淰isiting these technology parks, you can feel how they are modeled after the American agricultural extension system to help move new agricultural practices from scientists to farmers,鈥 新澳门六合彩内幕信息 Davis鈥 McGuire says. 鈥淏y partnering with the Cambodian scientists for this research, we are also helping to support those efforts to rebuild Cambodia鈥檚 agricultural extension system.鈥

Helping farmers make their own best decisions

Hok and his colleagues at the Royal University of Agriculture have been working with U.S. university researchers connected to the Horticulture Innovation Lab since 2010. He says these partnerships are an important part of the problem-solving process.

鈥淲e have the same goal, to extend successful agricultural technologies to benefit more farmers, especially smallholder farmers,鈥 he says.

Ultimately the team will distill the research findings into several documents aimed at helping farmers consider new practices, understand the trade-offs and make informed decisions about managing their farms.

鈥淚t all comes back to: How do we help make these decisions easier for farmers? They already have so much they鈥檙e dealing with,鈥 Vipham says.

鈥淚ncreasing productivity is important for generating income, but if I鈥檓 a farmer, what does that mean for conserving my resources? What does that mean for my ability to feed my children?鈥
