Indicators are increasingly recognized as an important decision aid tool to translate sustainability issue from theory into practice. However, indicator development for sustainable community development is rather successful than the agricultural sector due to methodological lacuna. The aim of this study is to develop a methodological framework for indicator development and an essential set of i...
We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India’s total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers. Spillovers and free-riding were dominant characteristics of technical change during the period studied. Alth...
A cross-sectional survey of agricultural areas, combined with routinely monitored mosquito larval information, was conducted in urban Dar es Salaam, Tanzania, to investigate how agricultural and geographical features may influence the presence of Anopheles larvae. Data were integrated into a geographical information systems framework, and predictors of the presence of Anopheles larvae in farmin...
In regions of India where cultivation is rainfed, the optimal time to plant coincides with the onset of the monsoon. In this paper, we elicit from farmers their prior beliefs about the timing of the monsoon and assess their accuracy by comparing them to historical data. We find substantial heterogeneity in beliefs and ∗Financial support from CRMG, GARP and World Bank is gratefully acknowledged....
Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...
Training programmes for rice farmers is believed to be an activity leading the improvement in yield if it well managed and implemented. Japan International Corporation Agency (JICA) initiated a training programme three regions Northern Ghana. Indeed, benefits of could social, cognitive, economic or both. The was intended help increase productivity profitability. This study set up evaluate exten...
Brazil is one of the largest suppliers commodities in world, partly due to agricultural expansion Cerrado biome that began 1970s. However, as areas with better soil and climate for agriculture become scarce, farmers advanced marginal lands, where precipitation less reliable rainfed crops. The overall goal this paper investigate implications occupying drier biome, which are likely more so future...
Abstract This study quantifies the impacts of climate change on yields and corresponding economic losses in six relevant crops that account for 65% harvested area Mexico are highly terms consumption value. The results show crop could decrease considerably during this century, especially rainfed management system. Under a high-emission scenario, large reductions expected by end century both irri...
Climate variability can induce uncertainty in yields, and threaten long term economic viability of rainfed agricultural enterprises in the absence of effective adaptation strategies. Enterprise mix diversification has been found to be an effective adaptation strategy for mitigating multiple sources of farm business risk in some contexts. The extent to which enterprise mix diversification can mi...
