    The Asia, Pacific and Oceania (APO) region is the centre of diversity of many important species of crops, animals and livestock. Most of its resource-poor farmers depend on this agrobiodiversity for food security and livelihood. Agrobiodiversity in APO has served as the source of genetic materials that propelled the Green Revolution in the region. It has enabled continuous growth in productivity, allowing agriculture to cope with declining yield, emergence of pests and diseases and occurrence of abiotic stresses like drought and floods.

    Demographic data

    Gender - Makwe and Guyu have more females in the scheme (60.5% and 55% respectively). Masholomoshe has the highest number of males (53.3%). Discussion with the sampled households revealed that male headed families hardly face labour problems, and high percentages of female irrigators have a negative impact when it comes to operation and maintenance. In terms of gender distribution there are more women irrigating than males.

    Agriculture in Ethiopia remains to be the key sector. It is still the main source of foreign exchange earnings (up to 90%) and the largest labour force employer (about 83%). Of the total agricultural output, about 95% was covered by smallholder agriculture sub-sector. However, a number of factors limit smallholder farmers from participating in export potential cash crops. The main objective of this paper is to identify household specific factors determining sesame production and marketing participation.

    Laos, Asia sudoriental

    This paper develops a hydro-economic optimization modeling framework to assess the economic consequences and potential trade-offs of various infrastructure development and policy pathways in the Nam Ngum Basin (Lao PDR). We considered whether large shifts in water resource demands in a relatively water abundant basin could induce meaningful economic trade-offs among water uses, including hydropower generation, irrigation expansion, flood control, and transboundary water transfer objectives.
