Alternate wetting and drying (AWD) is a low-cost innovation that enables farmers to adapt increasingly water scarcity conditions (such as drought), increase overall farm production efficiency, mitigate greenhouse gas (GHG) emissions. It seen pathway for transforming agri-food systems into more resilient, productive, biologically diverse, equitable forms, ensuring our commitments the UN Sustainable Development Goals (SDGs). This paper uses scaling up uncertainty frameworks review success...
Rice is the staple food and provides livelihood for smallholder farmers in coastal delta regions of South Southeast Asia. However, its productivity often low because several abiotic stresses including high soil salinity waterlogging during wet (monsoon) season water dry season. Development dissemination suitable rice varieties tolerant these multiple encountered zones are prime importance increasing stabilizing productivity, however adoption new has been slow this region. Here we implemented...
Abstract Using survey dataset collected from nearly 9000 farmers along with pedigree and evaluation data, this study measures the contribution of International Rice Genebank (IRG) to varietal improvement rice productivity in Eastern India. We empirically test relationship ancestry changes while controlling for effects other farm inputs environmental factors. Estimated coefficients indicate that a 10% increase genetic IRG accessions an improved variety is associated yield 27%. Through...
Neighborhood and spillover effects on technical efficiency were investigated among 270 randomly drawn farming households from 18 irrigated villages in Guimba, Nueva Ecija, Philippines, using a two-step procedure. In the first stage, stochastic frontier production function was used to estimate farmer’s efficiency; second appropriate spatial econometric models of estimated. Spatial adopted this study detected dependency error term model across seasons locations, which can be associated with...
Abstract Background The International Rice Genebank (IRG) currently safeguards the largest and most diverse collection of rice genetic resources in world. Over past decades, from IRG have been used effectively to increase smallholder farmers’ productivity developing economies. Bangladesh is one direct indirect recipients germplasm for improvement. This study aimed map impact pathways transfers Bangladesh, evaluate contribution germplasms farmers, compute equivalent economic benefit. Methods...
Participatory Varietal Selection (PVS) is the selection by stakeholders of varieties in advanced testing stages plant breeding programs. With Burundi as a case example, this study incorporated qualitative Focus Group Discussions (FGDs) into quantitative PVS structure so to elicit deeper insights rice trait preferences and illuminate broader issues affecting farmers. During two consecutive years, surveyed 174 participants across six stakeholder groups (administrators, farmers, custom millers,...

Abstract (Keywords: migration, remittances, income, rice, farming systems) Out migration from rural areas is increasingly becoming a strategy to get out of poverty. While rice–based agriculture remains be the backbone in Southeast Asia, majority households particularly those who produce rice under rainfed conditions remain poor and insecure. This paper examines relationship between other socio-economic factors on household income using data 1,874 sample Vietnam (north south), Thailand...
