A number of major agricultural exporting countries responded to high food prices from 2007 to 2010 by imposing export restrictions on agricultural commodities in efforts to constrain domestic food-price inflation. These restrictions reduced the volume of internationally traded food, and...

Between March and August 2005 Niger was hit by a doubling of millet prices and a sharp rise in the number of severely malnourished children admitted to feeding centres. The extent and causes of such crisis remain controversial. The paper reviews the evidence in this regard in the light of the...

Food security has always been a key resilience facet for people living in cities. This paper discusses lessons for food security from historic and prehistoric cities. The Chicago school of urban sociology established a modernist understanding of urbanism as an essentialist reality separate from...

This paper uses fuel ethanol from corn as an example to establish a theoretical model and framework to explore possible impacts of developing bioenergy on food security in China under short run and long run dynamic equilibriums with import supplements. From the three aspects including...

Mitigating nutrient loss is a prerequisite of sustainable agriculture in the tropics. We evaluated three soil and water conservation technologies (mulching, minimum tillage and tied ridging) for two cropping seasons (long rains 2011, short rains 2011) at two sites in the central highlands of...

This paper analyzes the effect of the shallow water table on water use of the winter wheat (Triticum aestivum L.) that has replaced alfalfa (Medicago sativa) on the irrigated lands of the Fergana Valley, upstream of the Syrdarya River, in Central Asia. The effect of the shallow water table is...

While biofuels have currently been regarded as a good alternative for fossil fuels, there remain many debates on their impacts on human and environment. This paper tried to shed light on bio-ethanol in Brazil as one of the main producers and exporters in the world. The main question was to...

We investigate how food-aid affects price and production of staple food, with a partial equilibrium model with non-separable production and consumption. The model captures the key characteristics of sub-Saharan Africa subsistence economies. Simulations generate negative but also positive...

This paper explores the reduction of food insecurity in Bolivia, adopting a supply-side approach that analyzes the role of agricultural spending on vulnerability to food insecurity. Vulnerability to food insecurity is captured by a municipal-level composite indicator for all 327 municipalities...

Studies investigating the effects of wheat export controls on the domestic market in the exporting country itself are scarce. This paper analyses the domestic market impact of wheat export controls in Russia and Ukraine during the 2007/2008 global food crisis within a spatial price transmission...
