Measuring the effectiveness of extension innovations for out-scaling agricultural technologies
Low adoption levels of agricultural technologies undermine the impacts of national and international agricultural research. Using a combination of an ordered logit and Heckman selection models and a case study from an ...
Influence of putative forest refugia and biogeographic barriers on the level and distribution of genetic variation in an African savannah tree, Khaya senegalensis (Desr.) A. Juss
Phylogeographic studies of tropical and subtropical
tree species provide an ideal method to study the role of forest
refugia in the structuring of genetic diversity in contemporary
populations. To date, most studies have ...
ICARDA Efforts to Promote In Situ/On-farm Conservation of Dryland Agrobiodiversity
Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, ...
Commercial behaviours of smallholder farmers in wheat seed use and its implication for demand assessment in Ethiopia
The article presents the commercial behaviour and its determinants of smallholder farmers in wheat seed use, and its implication for seed demand assessment, based on primary data from 524 wheat farmers in the major wheat ...
Do faba bean (Vicia faba L.) accessions from environments with contrasting seasonal moisture availabilities differ in stomatal characteristics and related traits?
Drought is a major constraint to faba bean (Vicia faba L.) production, and there are many mechanisms by which leaves can regulate water loss. Our primary objective was to test if the origin of the faba bean accessions, ...
Mapping soil erosion hotspots and assessing the potential impacts of land management practices in the highlands of Ethiopia
An enormous effort is underway in Ethiopia to address soil erosion and restore overall land productivity.
Modelling and participatory approaches can be used to delineate erosion hotspots, plan site- and context-specific ...
Estimating soil erosion in sub-Saharan Africa based on landscape similarity mapping
Soil erosion is one of the major forms of land degradation in sub-Saharan Africa (SSA) with serious impact on agricultural productivity. Due to the absence of reliable data at appropriate resolution and differences in the ...
Targeting perennial vegetation in agricultural landscapes for enhancing ecosystem services
Over the past century, agricultural landscapes worldwide have increasingly been managed for the primary purpose of
producing food, while other diverse ecosystem services potentially available from these landscapes have ...
Introducing new agricultural technologies and marketing strategies: A means for increasing income and nutrition of farm households in Ethiopia
Many developing regions have excellent potential agricultural resources. However, historically, the population has become so concentrated in these regions that acute poverty and malnutrition now predominate. The food ...
Data on how tree planting and management practices influence tree seedling survival in Kenya and Ethiopia
Understanding which trees farmers prefer, what determines their survival and enhancing farmer knowledge of tree management is key to increasing tree cover in agricultural landscapes. This article presents data on tree ...
