In August 2007, the Secretariat of the United Nations Framework Convention on Climate Change (UNFCCC) published a technical paper, Investment and Financial Flows to Address Climate Change, which estimated that USD200?210 billion in additional investment will be required annually by 2030 to meet global greenhouse gas (GHG) emissions reduction targets.

Reviewing the Stern Report (Stern, 2006), Martin Weitzman notes

Agriculture is one of the largest emitters of greenhouse gases. Greenpeace's new report Cool Farming details the destructive practices resulting from industrial agriculture and presents workable solutions to help reduce its contribution to climate change. These practical changes will benefit the environment as well as farmers and consumers throughout the world. This report details for the first time all direct and indirect contribution agriculture has on climate change.

This report reviews the terrestrial Essential Climate Variables (ECVs), which are endorsed by the UNFCCC and the Group on Earth Observations (GEO). Details are provided on why these observations are needed to understand the causes of climate change, analyse the potential impacts, evaluate the adaptation options and enable characterization of extreme events such as floods, droughts and heat waves.

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.
