La degradación de pasturas es un problema serio en América Tropical, pues se estima que entre un 50-80% de las áreas de pasturas están degradadas (Días-Filho, 2005), y sólo en América Central éstas representan casi 7 millones de hectáreas (Betancourt et al., 2007). Con frecuencia se acepta que las pasturas [...]

The focus in this thesis is to form a view of how well soil fertility research performs within the ever shifting smallholder contexts. This study examined application of agroecological knowledge for soil fertility management by smallholder farmers, with the view to enhancing the utility of research among resource-deprived farmers of western Kenya. [...]

This article focuses on the context of the Millenium development goals (MDG) and improving and maintaining soil fertility in Africa.

This study was undertaken to identify farm and farmer characteristics that may influence dissemination of seed and knowledge of improved fallows and biomass transfer, to whom, how and what is disseminated. This was done by carrying out a formal and informal survey involving a random sample of 120 farmers from [...]

A study to improve soil fertility and farm productivity under intensive crop-dairy smallholder farming systems was carried out in Kiambu District, central Kenya highlands in the period 2003-2005 using farmer field school approach.

The SRI (System of Rice Intensification) Facilitators Guide is intended to support farmers’ learning in SRI. It recognizes that there is no one lesson, single strategy, program or course that meets all the needs of farmers in SRI methodology. Supporting farmers in acquiring SRI skills requires on-going work by Facilitators/Development [...]

This study was conducted to determine the effectiveness of the Farmer Field School (FFS) approach in knowledge acquisition, adoption and dissemination of soil management technologies (SMTs) among small-scale farmers in Kenya. Eight technologies were scaledout using the FFS approach and conventional extension methods. A survey methodology with the ex-post facto [...]

Agricultural extension systems in sub-Saharan Africa are increasingly using participatory approaches to improve technology adoption by smallholder farmers. This approach has been successful particularly in low-rainfall areas, where adoption is traditionally slow. Crop productivity, farm incomes and food security have improved as a result. ICRISAT worked with Zimbabwe’s Department of [...]
