Many biofuels are associated with lower greenhouse gas emissions but have greater aggregate environmental costs than gasoline.

This paper analyses the determinants of vulnerability to food insecurity among male and female-headed households in Kwara state of north-central Nigeria.

Poverty remains to be the most important development issue facing India with an estimated 301.72 million Indians (27.5 percent) living below the poverty line in 2004-2005. In 1975, Ralegan Siddhi was just another drought prone, poverty stricken village, but it has had much success in poverty reduction since then.

This paper provides an overview of selected trends and conditions of ecosystem services, in particular, food production and impacts on the environment based on the Millennium Ecosystem Assessment. It then describes outcomes for future ecosystem services under alternative development pathways, with a focus on tradeoffs between food security and the environment, such as implications for fertilizer use, and the role of biofuels.

This document addresses the hunting of tropical forest wildlife for food (known as

Several studies addressing the supply and demand for food in China suggest that the nation can largely meet its needs in the coming decades. However, these studies do not consider the effects of climate change. This paper examines whether near future expected changes in climate are likely to alter this picture. The authors analyze the effect of temperature and precipitation on net crop revenues using a cross section consisting of both rainfed and irrigated farms.

The paper begins by laying out the current state of global food insecurity and malnutrition, including magnitude, trends and future projections. The causes, consequences and costs of food insecurity and malnutrition are explored. Malnutrition is clearly a severe impediment to sustainable development and human security as it slows down economic growth and the achievement of equity. The paper briefly lays out a number of factors besides climate change, bioenergy and rising prices that will likely contribute to malnutrition in the future.

This paper begins by laying out the current state of global food insecurity and malnutrition, including magnitude, trends and future projections. It then explores the implications of climate change and rising bioenergy demand for nutrition. It also examines the direct nutrition effects of rising bioenergy demand, as well as its contribution to rising food prices. A chapter on policy implications provides a number of options for improving food security and nutrition, as well as for addressing the links between climate change and bioenergy demand on the one hand and nutrition on the other.

International treaties and national policies seek to enhance global efforts to mitigate and adapt to climate change. While it is important to continue to strive to reduce greenhouse gas emissions, mitigation alone is not enough and will not be felt before the second half of the century. Global warming is already underway and adaptation strategies are now a matter of urgency, especially for the most vulnerable poor countries, which are even now being disproportionately affected.

This highly illustrated guide helps health promoters, development workers, environmental activists, and community leaders take charge of their environmental health. In small villages and large cities, A Community Guide to Environmental Health can provide the tools, knowledge, and inspiration to begin transforming the crisis in environmental health. This book contains activities to stimulate critical thinking and discussion, inspirational stories, and instructions for simple health technologies such as water purification methods, safe toilets, and non-toxic cleaning products.
