Rubyogo, Jean-ClaudeSperling, L.Assefa, T.[A new approach for facilitating farmers´ access to bean seed]A new approach for facilitating farmers´ access to bean seed

New bean varieties translate into increased on-farm yields only if farmers obtain access to desired seed. Conventional models of legume seed delivery in Africa, centralized with the National Agricultural Research Systems (NARS), prove to be slow and of limited reach. This article describes a nove...

The Rwandan civil war escalated in 1994, killing 800 000 people and displacing another 2 million. Agriculture, the occupation of over 90% of the Rwandans was acutely affected as violence peaked in the middle of the growing season. This article analyses the effects of the war on bean varietal dive...

This work analyses on-farm adjustments in land allocation and intensification in a commercial crop following the increases in market demand in a developing economy. Drawing from the survey conducted among common bean producers in Ethiopia in 2008, a two stage econometric method was used to invest...

Varietal selection is particularly difficult for very heterogeneous environments where farmers have a range of preferences. To address these issues in Rwanda, local bean experts, generally women, are invited to the research station to assess cultivars and to select those they prefer for their plo...

This paper describes two techniques used in Rwanda for integrating farmer expertise into bean varietal development. Standard farmer evaluation of on-farm trials can help: 1) indicate how varieties perform under farmer conditions; 2) better identify criteria critical to farmers; 3) target varietie...
