Wetlands of Ecosystem Functions, Services and Impacts of Wetlands of the Hindu Kush Himalayan

Diverse wetland types KYRGYZSTAN UZBEKISTAN – peatlands, glaciated TAJIKISTAN TURKMENISTAN lakes, springs, marshes, floodplains, Yellow R. manmade AFGANISTAN

Brahmaputra R.

PAKISTAN Comprise 17% of the IRAN HKH region area

INDIA Ecosystem Services

Regulation of hydrological regimes

9 largest Asian rivers Yellow have headwaters Indus in HAWs, basins of Brahmaputra which support 29% of global population

Mekong Ecosystem Services (2)

Carbon sequestration

Ruoergai marshes in China store 750 million tonnes of carbon – 7.5 times the annual fossil fuel emissions of transportation sector of China Ecosystem Services (3)

• Hotspots of biodiversity

Bar headed geese use the Rourgei marshes and HAWs of Bhutan as breeding grounds

Trout River of - High altitude wetlands are the habitats of cold fish Ecosystem Services (4)

• Cultural linkages and support to livelihoods

Rourgei marshes support more than 50,000 Tibetan herders

Several high altitude wetlands as in Nepal have religious and spiritual significance , especially for and Buddhists Causes of wetland degradation

Extremely vulnerable to wide range of human and environment driven threats • Water diversions • Drainage for agriculture • Overgrazing • Climate change induced stresses Climate change in the Himalayan Region

Rapid increase in Glacial melt, which contributes 4 – 45% of the river base flows

Increased variability of flows , frequent droughts and floods

Shifts in biodiversity – vulnerability of species with restricted habitat availability

High levels of vulnerability within communities Wetlands and Climate Change

Wetlands can contribute significantly to climate change adaptation

• Regulation of hydrological regimes – storing peak flows, augmenting lean flows

• Storing carbon – peatlands

• Supporting biodiversity

Wetland degradation enhances vulnerability to climate change Wetlands within Jhelum Basin

•70% of area under marshes converted for agriculture and plantation Changes in Water Flows

Increasing glacial melt leading to higher flow volumes and early onset of high flows

Increased vulnerability due to loss of wetlands • lower moderation of peak flows • lower lean season flows due to reduced absorption capacity

Wetlands and River Basin Management

Headwater wetlands provide water resource Downstream wetlands functions e.g. provide local goods and • protection services: e.g. • low flow support •fish • agriculture • recreation

• Functioning of HAWs critical to ensure sustained provisioning of ecosystems services in the downstream reaches • Wetland conservation and wise use as alternate to structural approaches Integrating Wetlands in Climate Change Adaptation

Aquifer-riverbed Current status of policy integration

• Sectoral approach to wetlands and water management with limited degree of integration • Role of wetlands in water management and river basin management not explicitly recognized • Water allocation strategies focused on human uses without considering ecological requirements • Focus on role of state and community institutions in management of water resources – limited role of private sector , diffused incentive mechanisms • Urgent need for action as inadequate integration enhances vulnerability of large populations and ecosystems – especially on account of climate change Himalayan Wetland Initiative

• Database methodologies on Himalayan Wetlands • Mechanisms and facilities for cooperation, networking and capacity building • Improve knowledge of climate change impacts and of adaptation responses • Devise and promote best practices on Himalayan wetlands management • Develop participatory CEPA programmes • Develop policy support for implementation of wetland conservation Thank You
