Atmospheric Brown Clouds: Regional Assessment Report with Focus on Asia

This United Nations Environmental Programme report summary reports that an increasing amount of soot, sulphates and other aerosol components in atmospheric brown clouds (ABCs) are causing major threats to the water and food security of
Asia and have resulted in surface dimming, atmospheric solar heating and soot deposition in the Hindu Kush-Himalayan-Tibetan (HKHT) glaciers and snow packs. These have given rise to major areas of concern, some of the most critical being observed decreases in the Indian summer monsoon rainfall, a north-south shift in rainfall patterns in eastern China, the accelerated retreat of the HKHT glaciers and decrease in snow packs, and the increase in surface ozone. All these have led to negative effects on water resources and crop yields. The emergence of the ABC problem is expected to further aggravate the recent dramatic escalation of food prices and the
consequent challenge for survival among the world’s most vulnerable populations. Lastly, the human fatalities from indoor and outdoor exposures to ABC-relevant pollutants have also become a source of grave concern.

Country Environmental Analysis for the People's Republic of China

This Report by the Asian Development Bank is intended to provide the background information necessary for informed decision making on the environmental and natural resources constraints, needs, and opportunities and challenges faced by PRC, and to be used as a resource document for the upcoming preparation of the 2007–2011 Country Partnership Strategy (CPS 2007–2011) for PRC.

The report proposed eight recommendations to narrow this gap by prioritizing 'Early and Expanded Use of Market-Based Instruments to Promote Efficient Use of Natural Resources and Control Pollution.'
