The main goal of this report is to provide a brief summary of land-use change in Amazonia within the focus countries of Bolivia, Brazil, Colombia, Ecuador and Peru. This report will mainly focus on the analysis and discussion of land-use change status and trends since 1970’s, a period when considerable changes started to be evident. Analyses were supported from a literature review and land use databases and maps for Andean countries (CIAT) and Brazil (INPE).
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 presentación describe el las actividades y el plan de estudios del Programa de especialización de asesores rurales (PEAR) que tiene como objetivos la formación de técnicos asesores proveedores de asistencia técnica agro-pecuaria de calidad, que genere impacto sustentable en la producción, mediante su orientación al mercado y a la generación de capacidades locales
Esta presentación describe las actividades del Porgrama de investigación SGR: Desarrollo e implementación de recursos forrajeros para sistemas de producción bovina sostenibles en el departamento del Cauca, Colombia. Está dividida en seis partes: Introducción al proyecto; Marco teórico; Metodología; Resultados; Conclusiones; Recomendaciones
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.

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.
The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history.
This report assesses trends in investments, human resource capacity, and research outputs in agricultural R&D -excluding the private (for-profit) sector- in LAC. It is an update of Stads and Beintema (2009), covering a more complete set of countries and focusing primarily on developments during 2006-2012/2013.
