A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

To improve national food security, successive Mali governments have always focused on expanding and intensifying production in the government-managed irrigation schemes (Office du Niger), which account for about 50% of domestic rice production. Because the cost of expanding and rehabilitating...

This paper attempts to build on a conceptual analysis of both land tenure and food security to set various links in a dynamic framework that captures both the effects of access to resources on food security and the effects of food security on access to and use of resources. This framework is...

In June 2005, OECD members met with senior government officials from Brazil to discuss Brazilian agricultural policies and future directions, as a part of a comprehensive agricultural policy review. Ongoing dialogue with Brazil on policy issues is important to fostering a better understanding of...

South Korea is a highly urbanized and industrialized country. Increased urbanization and greater specialization have led to rising incomes, and changes in food production and consumption patterns. Changes in consumption and increased production specialization have also resulted in changes in...

Since the 2007–08 food crisis, many thoughtful analyses have addressed the causes and impacts of high and volatile international food prices and proposed solutions to the crisis. These studies have covered global as well as local food price dynamics and policy reactions. The food price problem...

Tajikistan is classified by the World Bank as one of the CIS countries that are most vulnerable to climate change risks. This paper provides a closer look at a set of variables that determine Tajikistan’s vulnerability to risk in general and to climate change risk in particular. After...

Integrated land use models (ILM) are increasingly applied tools for the joint assessment of complex economic-environmental farming system interactions. We present an ILM that consists of the crop rotation model CropRota, the bio-physical process model EPIC, and the farm optimization model...

Nitrate pollution from agriculture is an important environmental problem, caused by the excessive use of inorganic fertilizers. The internalization of this externality, via a tax on mineral nitrogen, could lead to a second best solution, reducing nitrate emissions. Several authors suggest that a...
