This report finds that bioenergy’s water demands are in large part linked with the cultivation and processing of feedstocks, such as crops, which in turn have important implications for sustainable agriculture, land use and food production.

Against the current challenges to enhance food security worldwide, the publication aims at illustrating the importance of healthy ecosystems for the provisioning of key services that contribute to food security. Such ecosystem services are water provisioning and food production.

This UN report examines the critical role of forests in a green economy, and provides policy recommendations to radically transform the forest sector such that it can lead to sustainable development and poverty eradication.

Scientific evidence and new analyses demonstrate that control of black carbon particles and tropospheric ozone through rapid implementation of proven emission reduction measures would have immediate and multiple benefits for human well-being. Black carbon exists as particles in the atmosphere and is a major component of soot; it has significant human health and climate impacts.

Efforts to limit climate change generally focus on reducing carbon dioxide emissions caused by burning fossil fuels. However, another byproduct of fossil fuel combustion is black carbon, a major component of soot. Sources include diesel truck and car engines as well as wood fires, kilns, and stoves.

This report examines how the public-private partnership (PPP) model can be applied to help promote sustainable housing and urban development for countries around the world. The report has two main parts.

The UNEP has launched a report titled "Taking Steps Toward Marine and Coastal Ecosystem-Based Management: An Introductory Guide." The report highlights how planners and policy makers in local, national and regional governments can adopt an ecosystem-based management (EBM) approach to help ensure sustainable development for marine and coastal environments and the livelihoods that depen

The UNEP, under its Capacity Development for the Clean Development Mechanism (CD4CDM) project, has published a paper on the Clean Development Mechanism (CDM), which focuses on the equitable distribution of CDM projects.

In October 2007 the UN Chief Executives Board approved the UN Climate Neutral Strategy, which committed all UN agencies, funds and programmes to move towards climate neutrality within the wider context of greening the UN.  This report provides a progress update on implementation of the strategy.
