Aflatoxins are poisons that occur naturally in the environment. They are produced mainly by the Aspergillus flavus and Aspergillus parasiticus fungi, which can affect many of important staple crops: maize, sorghum, millet, rice, oilseeds, spices, groundnuts, tree nuts, and cassava. Hot, humid,...

This is a draft paper, submitted in advance of presentation at the 2014 Annual Meeting of the Agricultural & Applied Economics Association.

This paper quantifies the economic impacts of flooding in the Ba River and Penang River catchments in Viti Levu, Fiji. We conducted a detailed assessment of flood damage stemming from two major flooding events in 2012 that severely affected the two important catchments, primarily by using...

Faster agricultural development requires understanding whether the inverse land size-yield relationship exists or not. To verify the presence of this relationship, this study decomposes a yield index into separate components attributable to (1) efficiency, (2) soil quality, (3) land size, (4)...

This paper analyses the household level drivers of agricultural output in Nyabihu District, a densely populated area of rural Rwanda, over the past 26 years. We use a unique two-wave panel dataset spanning a 26-year period, linking the split-off households in 2012 to the original households in...

Constrained access to land is increasingly recognized as a problem impeding rural household welfare in densely populated areas of Africa. This study utilizes household and plot level data from rural Kenya to explore the linkage between land access and food security. We find that a 10% increase...

This paper studies the effect of local off-farm employment and migration on rural households’ technical efficiency of crop production using a five-year panel dataset from more than 2,000 households in five Chinese provinces. While there is not much debate about the positive contribution of...

Climate change will directly affect food availability and security. Because food production is fundamentally a biological process that is a function, in part, of temperature and moisture, the agricultural sector’s potential vulnerability is particularly large. While there is ongoing scientific...

This study examined the effects of China’s grain subsidy program, the largest food self-sufficiency project in the developing countries, on grain-sown areas within a context of liquidity constraints. A large household level panel was used to evaluate how the subsidy affects the cultivation...
