Genome mapping in cassava improvement: Challenges, achievements and opportunities por Fregene, Martin A., Okogbenin, Emmanuel, Mba, C, Angel, F., Suarez, MC, Gutiérrez Artunduaga, Janneth Patricia, Chavarriaga Aguirre, Paul, Roca, W., Bonierbale, Merideth W., Tohme, Joseph M.

“…The consequences are that cassava production fails to keep up with demand, especially in regions where over90% of yield is consumed as food, leading to an increase in acreage of cassava fields mostly into marginal lands. The advent of molecular markers,genome studies and plant genetic transformation holds promise of providing ways around breeding obstacles in long growth cycle and heterozygous crops. …”

Spatial and seasonal diversity of wild food plants in home gardens of Northeast Thailand por Cruz García, Gisella S., Struik, Paul C.

“…Data were collected in 77 sampling sites corresponding to five different home garden spatial configurations, namely fenced plot, fenced plot margin, yard, home garden boundary, and pot. Absolute abundance and frequency of occurrence were quantified per individual WFP species in both dry and rainy seasons, and data on additional uses (besides food) were collected through focus group discussions for each WFP species. …”

Neotropical savannas: prospects for economically and ecologically sustainable crop-livestock production systems por Spain, James M.

“…Contrary to the view held by many developers and some scientists, most savanna ecosystems are quite fragile and farmers and ranchers are confronting serious problems of resource degradation and marginal economic viability. New strategies and, in some cases, new germplasm and technology are needed to counter these problems. …”

Community participation in decentralized management of natural resources in the southern region of Mali por Umutoni, Clarisse, Ayantunde, Augustine A., Turner, M., Sawadogo, G.J.

“…The results suggest that women are marginalized. Presently, the big challenge that faces the institutions governing natural resource use in the study area is the system of representativeness in the community in the development of local rules and norms as community leaders and household heads often dominate, which does not encourage active participation of community members. …”
