In the Environment sector, UNDP works with the Palestinian government to protect the environment and to sustainably manage natural resources.  Sustainable management of natural resources is essential for the survival of communities and the very basis for national development. UNDP also promotes climate change mainstreaming, adaptation and mitigation to respond to the potentially increasing scarcity of natural resources and manage climate change associated risks.  UNDP has been working very closely with key Palestinian institutions at the national and local level to address the environmental issues and concerns and develop the needed infrastructure to control pollution and prevent degradation of natural resources. The environment and natural resources portfolio in the West Bank, including East Jerusalem, and Gaza Strip is approximately USD 25 million.
