Some of the most promising and at the same time some of the most challenging areas of future food production are found in the savannas of South America. Integrating cropping, livestock, and forestry in these regions can increase the eco-efficiency of agricultural production. This chapter presents a case study of an integrated crop, livestock, and forestry system in Brazil. The study area is in Goiás State in the Cerrado region, a vast savanna covering almost one quarter of Brazil's land area.
Genetic improvement on local breeds kept by small farmers in developing countries is challenging. Even though good pedigree and performance recording is crucial and an important component of breeding programs, it remain difficult or next to impossible under conditions of subsistence livestock farming. This means that standard genetic evaluations, as well as selection and planning of mating based on estimates of the animals' genotypes, cannot be done at any level in the population of the target breed or genetic group.
Esta obra se base en los conocimientos y las experiencias de un grupo de administradores y evaluadores de 12 organizaciones, tanto nacionales como internacionales, que llevaron a cabo una serie de estudios de evaluación en Bangadesh, Cuba, Ghana, Nicaragua, Filipinas y Vietnam.
Este documento describes las actividades desarroladas por CGIAR y Colombia que ha servido extremadamente bien como sede para la investigación eco-regional que hace el CIAT y también ha facilitado las transferencias de nuevas tecnologías desde América tropical hasta África al sur del Sahara y el sudeste asiático. Además, la sede del CIAT en Cali ha servido de punto lógico para las operaciones regionales de otros Centros patrocinados por el CGIAR —en particular Bioversity International y el Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT)
This guide is the second in a series of documents designed to support agencies implementing participatory agroenterprise development program operating within defined geographical areas.
This booklet is the third in the CIAT in Asia Research for Development series. It was based on the experiences of researchers and farmers working with the AusAID-funded Forages for Smallholders Project (FSP) in Southeast Asia from 1995 to 1999. This project was a partnership of smallholder farmers, development workers and researchers who were using participatory approaches to developing forage technologies on farms.
Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.

Coordinated formal efforts to generate technologies for enhancing agricultural development in Ethiopia was mainly rooted in formal research and development institutions up to very recently. A number of improved technologies have been generated wlth the efforts made so far and the superiority of some of the technologies over the traditional practices has already been proved, at least for the major commodities.
Global climate change and food security are complex and closely intertwined challenges. A key requirement for dealing with them successfully is that agriculture becomes more eco-efficient. As researchers work toward this goal, they must always ask, “Efficiency for whom?” Finding answers to this question requires that research be conducted from a systems perspective in a broadly participatory manner involving complex collaborative arrangements.
