The literature on the impacts of biofuels on food prices is characterized by contradictory findings and a wide range of estimates. To bring more clarity to this issue, we review studies on U.S. corn ethanol expansion released between 2008 and 2013. Normalizing corn price impacts by the increase...

Agriculture’s reliance on irrigation and concerns over water scarcity raise the question of how global food output and trade could be affected if the issue of water shortfall needs to be resolved on the back of agriculture. To understand changes in food production and international...

There are growing opportunities and demands for the use of biomass to provide additional renewables, energy for heat, power and fuel, pharmaceuticals and green chemical feedstocks. However, the worldwide potential of bioenergy is limited, because all land is multifunctional, and land is also...

This review describes that due to rapid globalization, vulnerability in different areas affects human life. With rapid population growth, securing the inherent vulnerability of this relationship, whether social, economic, or environmental, has to be central to efforts to achieving sustainable...

Az élelmiszerárak növekedése 2006–2008 között a világ egyes térségeiben zavargásokhoz és a politikai stabilitás megrendüléséhez vezetett. Különösen fejlődő országokban súlyos a helyzet, ahol a legszegényebb rétegek jövedelmük döntő hányadát élelmiszerekre...

Genetically-modified (GM) rice is an important technology surrounded with controversy and uncertainty, hence it warrants more in-depth analysis. While GM rice is considered by its supporters as having promising potential, many still remain passionately against its use. This study assesses the...

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 paper builds a model determining optimal capacities of diversion dams or water transfer projects. The model incorporates stochastic inflows to the dams and the role of the dam capacity in reducing overflows, and gives a closed-form expression of the marginal benefit of capacities....

This paper deals with the social implications of ethanol expansion in Brazil. The evolution of the labor market in sugar cane production in the country is analyzed together with its regional patterns of expansion, to illustrate how the changes in the recent expansion are modifying the...

The study identified factors that influence the adoption and contribution of conservation agriculture (CA) on household food security among smallholder farmers. To determine factors that affect the adoption of CA among smallholder farmers, a probit regression model was used. Then, the study...
