For half of the year, the Rann of Kutch is a vast salt flat — bleak, hot, and dusty. But for the other half it's a huge marsh teeming with flamingos and hundreds of other bird species. Commitments by both India and Pakistan to designate Ramsar sites within this transboundary area will help protect these unique wetlands, and the wildlife and people that depend on them.
At this time of year, it's hard to believe that the Rann of Kutch has wetlands of international importance.
Spanning the border of India and Pakistan on the Arabian Sea, the Rann of Kutch has been described as 'a desolate area of unrelieved, sun-baked saline clay desert, shimmering with ... a perpetual mirage'. Indeed, Rann itself means 'salty desert'. But between May and October it's a different place altogether.
The salt flats are flooded with run off from monsoon rains together with sea water driven by high winds and tides from the Arabian Sea, transforming them to marshes teeming with wildlife. The marshes support over 200 species of birds, including one of the world's largest breeding colonies of greater and lesser flamingos (Phoenicopterus ruber
and P. minor
), the threatened lesser florican (Sypheotides indica
), cranes, storks, and two endangered bustards, the great Indian bustard (Ardeotis nigriceps
) and houbara bustard (Chlamydotis undulata
As well as the seasonal marshes, the area's coastal wetlands — estuaries, brackish lagoons, tidal mudflats, and permanent saline marshes — support over 40,000 wintering and resident water birds and waders. These include ducks, pelicans, egrets, herons, plovers, and sandpipers.
The coastal wetlands are also an important source of shrimp farming for hundreds of communities living in the area. Despite the inhospitable conditions for most of the year, the Rann of Kutch is also home to many large mammals. These include the last population of the endangered Asiatic wild ass (Equus hemionus khur
) as well as locally endangered species such as striped hyaena (Hyaena hyaena
) desert cat (Felis lybica
), caracal (Felis caracal
), honey badger (Mellivora capensis
), chinkara (Gazella bennettii
), nilgai (Boselaphus tragocamelus
), and wolf (Canis lupus
The desert is also home to a variety of reptiles, including the endangered Indian monitor (Varanus bengalensis
), Indian sand boa (Erys johni
), and saw-scaled viper (Echis carinatus
During the wet season, animals shelter in the few areas of higher ground. These sandy, salt-free regions are known as bets
, and also provide a place for plants to grow, including the region's only large trees.
The Rann of Kutch has been shaped by a variety of geological processes. Once part of the Arabian Sea, geological uplift closed off the connection and created a vast freshwater lake that was still navigable during the time of Alexander the Great, 2,350 years ago. Over the centuries, silting created the vast mudflat that is now only flooded during the brief wet season.Earthquakes too have played a key role. In 1819, a devastating earthquake that wiped out villages and threw up a 90km-long ridge popularly known as the Allah Bund ("wall of God") also altered the course of the Sindhu River, leaving the Rann of Kutch without a freshwater supply.
A massive earthquake 800 years before this is also thought to have altered the landscape. The region is still frequently rocked by earthquakes, with the last big one in January 2001 destroying towns and killing more than 30,000 people.While only sparsely inhabited today, the Rann of Kutch has a firm place in human history, both modern and prehistoric. Genetic scientist Spencer Wells believes that the first migration of early man from Africa to Australia 60,000 years ago occurred in three stages: the first to the Middle East, the next to the Kutch region, and the third on to Australia. Those who stayed in the Kutch might have become part of a great civilization that predates the Mesopotamians.By 2600 BC, the Rann of Kutch was part of the Indus Valley, or Harappan, civilization, which controlled a vast area of some 650,000 square kilometres — twice as large as that controlled by Mesopotamia and Egypt at the same time. A major town from this time, Dholavira, which once controlled trade through the area, has been excavated in the Rann of Kutch.
These days, 18 different tribes live in the region, each with its own language and culture. Cut by the India–Pakistan border, the Rann of Kutch has not always been peaceful. But the wetlands hold the prospect for future cooperation. Last year, India and Pakistan committed to designate over 1.6 million hectares of the Rann of Kutch as Ramsar sites — wetlands of international importance. These commitments raise the hope that in the future, the two neighbours will work together to protect and manage one of the most biologically important wetlands in Asia. And further protection for the area is vital. Although part of the wetlands on the Indian side are already protected, the fragile ecosystem is under threat from cattle grazing, vehicular traffic, and cutting trees to make charcoal, even within the protected areas. There are also proposals to expand commercial salt extraction, which could adversely affect the wild ass population as well as the region's threatened bird species.
"The Rann of Kutch is unique," says Rahat Jabeen, Wetlands Conservation Officer at WWF Pakistan. "Not only are there are many different types of wetland habitats, but there are also desert habitats. The area supports many locally endangered and globally threatened species, and is essential for maintaining biodiversity."Archana Chatterjee, Wetland Habitats Coordinator at WWF-India, echoes this. "The Rann of Kutch is a critically important refuge for the Indian wild ass and is an important staging area for migratory waterfowl, including the Asian population of the lesser flamingo. In addition, large numbers of birds remain throughout the winter."The designation of Ramsar sites within the Rann of Kutch will help protect these unique wetlands, and the wildlife and people that depend on them. And, by committing to designations in a transboundary wetland, both India and Pakistan are also pledging to coordinate with each other to look after a shared natural area — a new era in the history of the Rann of Kutch.

Also known as Kuchchh, the Rann of Kutch stretches for over 2 million hectares across the northwestern Indian state of Gujarat and southern Pakistan's Sindh province. Two major areas are recognised, the Great Rann (700,000 hectares in India and 770,000 hectares in Pakistan) and the Little Rann (495,300 hectares). The vast saline plain of the Great Rann stretches eastwards from the eastern edge of the Indus delta in Pakistan, bounded to the west by the Arabian Sea, to the south by the Peninsula of Kuchchh, and to the north and east by the Great Thar Desert. The India–Pakistan border passes through the northern edge of the Great Rann. In the southeast, the Great Rann links by a narrow channel to the Little Rann which, in turn, is linked with Gulf of Khambhat through a marshy depression.
WWF's work in the Rann of Kutch
The Rann of Kutch is one of WWF's Global 200 ecoregions
— a science-based global ranking of the world's most biologically outstanding habitats and the regions on which WWF concentrates its efforts. In addition to working on the Ramsar site designations, WWF has a number of projects in the area. In Pakistan, for example, WWF is working in collaboration with the Sindh Wildlife Department to conduct a regular census of birds in the Lower Sindh, which includes the Rann of Kutch, to survey the wetlands, and to protect the habitat of the sarus crane in the Nagarparker area. In addition, the Rann of Kutch is one site where WWF-Pakistan is working to implement a Global Environment Facility (GEF)-funded project on conservation of Protected Areas through community-based management.
India has pledged to designate 1.1 million hectares of the Rann of Kutch wetland as a Ramsar site, and Pakistan has designated 566,375 hectares. Designation of shared wetlands or transboundary wetlands is a priority issue for the Ramsar Convention on Wetlands. Ramsar Convention on Wetlands
Signed in 1971 in the city of Ramsar, Iran, the Ramsar Convention 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 currently (January 2003) 135 Contracting Parties to the Convention, with 1,235 wetland sites, totalling 106.6 million hectares, designated for inclusion in the Ramsar List of Wetlands of International Importance. Wetlands are defined to include rivers, lakes, swamps, and marine areas less than six metres in depth. Member countries of the treaty are obliged to do three things:• Manage all wetlands sustainably, promoting the wise use of all wetlands within their territory.• Consult with other Parties about the implementation of the Convention, especially with regard to trans-frontier wetlands, shared water systems, shared species, and development projects affecting wetlands. • Designate wetlands that meet the criteria for inclusion in the List of Wetlands of International Importance for conservation.
The geographical designations given here do not imply the expression of any opinion whatsoever on the part of WWF concerning the legal status of any country, territory, or area, or concerning the delimitation of its frontiers or boundaries.
