IUCN - The World Conservation Union
Founded in 1948, IUCN - The World Conservation Union brings together states, government agencies and non-governmental organizations in a unique world partnership. Its mission is to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable. Areas of focus include biodiversity; business; climate change; economics; ecosystem management; education and communication; environmental law; forest conservation; gender, marine and protected areas; social policy; species; wetlands and water. Details about IUCN's organizational structure, members, news updates; publications, online bookstore and contact information are available online.

The Ramsar Convention on Wetlands
The Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. There are presently 138 Contracting Parties to the Convention, with 1328 wetland sites, totaling 111.9 million hectares, designated for inclusion in the Ramsar List of Wetlands of International Importance.

Ramsar Sites Database Service
The Ramsar Sites Database Service provides information on wetlands designated as internationally important under the Convention on Wetlands (Ramsar, 1971). These wetlands are commonly known as Ramsar Sites. Information on wetland types, land uses, threats, hydrological values of the sites are available in this searchable database. Other components include the Ramsar Sites Directory, a summary of why the Site is important, and full scientific names of key species recorded. Graphical profiles include a core set of (thematic) maps and graphical analyses such as maps of the world and each region, showing the current distribution of the Contracting Parties and Ramsar sites or global distribution maps of Ramsar Sites with wetland types which have been identified as being under-represented.

IUCN Red List of Threatened Species
IUCN - The World Conservation Union, through its Species Survival Commission (SSC) assesses the conservation status of species, subspecies, varieties and even selected subpopulations on a global scale in order to highlight taxa threatened with extinction, and therefore promote their conservation. It provides the most comprehensive, apolitical global approach for evaluating the conservation status of plant and animal species. The goals of the IUCN Red List Programme are to identify and document those species most in need of conservation attention if global extinction rates are to be reduced; and provide a global index of the state of degeneration of biodiversity.

WWF - Pakistan
Established in 1970, WWF - Pakistan (WWF-P) contributes towards conserving Pakistan's unique natural diversity in a way that takes into account the future needs of its people. It is working to achieve the conservation of nature and ecological processes by preserving genetic, species and ecosystem diversity; ensuring that the use of renewable natural resources is sustainable both now and in the longer term and promoting actions to reduce pollution, and wasteful exploitation and consumption of resources and energy.

International Waters Learning Exchange and Resource Network (IW:LEARN)
The International Waters Learning Exchange and Resource Network's (IW:LEARN) mission is to build an Internet-based "global knowledge community" to protect, restore and sustain the world's aquifers, great lakes and river basins, coastal zones, seas and oceans. Sponsored by the Global Environment Facility (GEF) and its United Nations and World Bank partners, IW:LEARN specifically builds capacity among transboundary water resource projects worldwide.

WWF International
WWF's mission is to stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature, by conserving the world's biological diversity; ensuring that the use of renewable natural resources is sustainable and promoting the reduction of pollution and wasteful consumption. Its focus areas include climate change, forests, freshwater, marine, species and toxics. Cross-cutting issues include trade and investment (World Trade Organization rules), indigenous and traditional peoples (intellectual property rights), and the impacts of tourism. Particular attention is paid to the root causes of biodiversity loss, such as poverty, migration, macroeconomic policies, and poor enforcement of environmental legislation.
