Climate Change Adaptation and Impact Assessment for Munda Dam

Detailed description of project:

The proposed Munda Dam Project on the Swat River is located at the border of Khyber Pakhtunkhwa (KP) and Federal Administered Tribal Areas (FATA), at a distance of about 37 km north of Peshawar. According to the feasibility study carried out in 2000, the multi-purpose Munda Dam Project - upon completion - will generate about 2.4 billion MWh per year, provide irrigation water for more than 6,000 hectares of land and control floods downstream particularly in the Nowshera, Charsadda and Peshawar areas.

The Munda Dam Project is an excellent example for adaptation to climate change impacts by storing water for irrigation enabling farmers to cope with the variability of rainfall and adapt to the reduced water resources availability. As the frequency of floods in the future decades may significantly increase, the dam will control and regulate these floods. In addition, being a clean energy project, it will help mitigate climate change by avoiding the emission of green house gases. The project, when implemented, may also lead to improved stability and security in the conflict-impacted KP and FATA area, amongst others through socio-economic improvement of the local population’s livelihood.

The Pakistan Water and Power Development Authority (WAPDA) is responsible for the development of large hydropower and water sector projects. The French Development Agency AFD has funded through WAPDA the detailed design and preparation of tender documents for the Munda Dam project, which are expected to be finalised by June 2014.

In view of the economic benefits of the project to Pakistan, the European Union decided to fund a complementary study on climate change proofing and impact assessment.

Type of services provided:

Component 1: Improvement of the resilience of the Munda Dam Project towards climate change:

  • Assessment of the long-term development of rainfall and discharge in the river basin upstream of the dam;
  • Impact assessment of climate change on extreme floods and verification of the dimensioning of the dam’s spillway and gates to be integrated into Swat River Basin flood directive and water framework directive;
  • Impact assessment of temperature increases on evaporation from reservoir storage and its potential consequences on irrigation;
  • Analysis of the probability of increased frequency of extreme events in the upstream area of the dam, such as landslides and mudflows, and technical recommendations for the dam design;
  • Verification of the viability of the "flood storage" system in relation to climate change and increased flows including technical recommendations to adapt the system to changing discharges;
  • Analysis of the sedimentation linked to incoming water flows and technical recommendations for erosion safeguard measures;
  • Proposal of a strategic management system of water resources in the dam to address partially conflicting issues (allocation of relative priority to hydropower, flood protection and irrigation for river basin management).

Component 2 : Impact assessment study of the Munda Dam:

  • Environmental and social impact assessment concerning bio­diversity and quality of water resources, social and economic effects on resettled people, cultural resources, livelihood conditions, job opportunities, farming revenues, land repartition, environ­mental issues (GHG emissions and carbon footprint, CDM etc.).
