Using case studies for enhancing capacity in managing forest genetic resources por Boshier, D., Bozzano, M., Loo, J., Rudebjer, P.G., Cordero, J.

“…Lack of understanding of forest genetic resources (FGR) therefore constrains conservation of tree species, increases genetic risks in subsequent generations and hinders adaptation to climate change. Examination of tertiary forestry education curricula shows poor or no coverage of FGR issues, while biology teaching is often devoid of the social and practical realities. …”

Cassava cultivation and starch production in an Andean village por Strobosch, P

“…Twenty-four small-scale starch factories exist in the region, the constant demand for cassava has stimulated its production, although there has not been a major change in agricultural practices. Starch factories may be considered as simple or mechanical, processing 600 and 1200 kg of cassava/day, resp.; although in the latter, cassava shortage may reduce processing to 600-750 kg of cassava/day. …”

Crop improvement, adoption and impact of improved bean varieties in Sub Saharan Africa por Muthoni Andriatsitohaina, Rachel, Andrade, Robert Santiago

“…Although bean impact has been documented in a number of past studies, the last comprehensive study of the international crop improvement effort, organized by the Standing Panel for Impact Assessment (SPIA, formerly the Impact Assessment and Evaluation Group), was based on data collected a decade ago (Evenson and Gollin, 2003 based on 1997-98 data). Important changes have occurred in the funding and conduct of the international crop improvement effort and in the general climate for agriculture in the developing world since the completion of the Evenson and Gollin study.The level and focus of funding for research in the NARS and in the CGIAR centers have fluctuated greatly, and the role of the private sector has evolved. …”
