Research Environmental & Socio Economic Impact Assessment of Dams: A Case Study of Darawat Dam Jamshoro

This research aims to assess the environmental and socio-economic impact of the Darawat Dam in Jamshoro, Pakistan. It will analyze the potential problems related to the dam site and evaluate the upliftment of the area due to the dam construction. The study will provide suggestions for mitigation plans to reduce negative impacts and enhance positive effects. The methodology will involve formal and informal interviews with key informants and analysis of relevant literature. The outcomes will help improve the construction and management of the dam.

  3. Water is the vital resource to support all forms life on earth. Unfortunately, it is not evenly distributed over the world by season or location. Some parts of the world are prone to drought making water a scarce and precious commodity, while in other parts of the world it appears in raging torrent causing flood and loss of life and property. Throughout the history of the world, dams and reservoirs have been used successfully in collecting, storing and managing water needed to sustain civilization. Even today, water remain essential for the survivalof mankind and the future development of the world’s cities, industries and agriculture. As the world population continues to grow at the rate of over 100 million people each year, the fact that a significant portion of the available water in the world is toocontaminated for domestic use makes this situation very critical. • Water is the vital resource to support all forms of life on earth. Unfortunately, it is not evenly distributed over the world by season or location. • Some parts of the world are prone to drought making water a scarce and precious commodity, while in other parts of the world it appears in raging torrent causing flood and loss of life and property. • Throughout the history of the world, dams and reservoirs have been used successfully in collecting, storing and managing water needed to sustain civilization. • Introduction

  4. Even today, water remain essential for the survival of mankind and the future development of the world’s cities, industries and agriculture. • Govt of Pakistan intend to develop land and water resources of the country for irrigated agriculture development, Hydro power, flood control, socio economic uplift, emancipation of poor and needy people of the area.

  5. Problem Statements • Every year or a two, there are heavy torrential rains on mountain tops, which create heavy floods at downwards in plain areas. These floods results in loss of: • precious life, • live stock, • Crops, • Property (houses, roads, bridges etc) • Waste (unutilized) of precious rain water

  6. Study Area • Darawat Dam is located across Nai Baran near Jhangri village in Jamshoro District. The dam site is about 70 kms west of Hyderabad and 135 kms North East of Karachi and accessible from Karachi – Hyderabad super highway. The command area falls in Thatta District.

  7. Salient Features (Darawat Dam) Type Concrete Faced Rockfill Dam Length 225 m (738 ft) Top width 9 m (30 ft) Height 43 m (141 ft) Power Generation 300 kw Spillway Capacity 208,900 Cusec Life of the dam 100 years

  8. Reservoir Reservoir Area 10,500 Acres Gross storage 119,546 Acre ft Dead storage 32,283 Acre ft Live storage 87,264 Acre ft • Irrigation System High Efficiency Irrigation System Drip and Sprinkler Command Area (CCA) 50,000 to 80,000 Acres • Cost of Project Rs. 18.085 Billion • Construction Period 3 Years

  9. Objectives of Research The Govt of Pakistan intends to protect loss of precious life and property and uplift the area through construction of dam. Therefore, this study will focus on: • The prediction of environmental problems related to dam site. • Assessment of socio economic uplift of the area due to dam construction. • To raise awareness of the potential implications of the dam. • Development of mitigation plan to decrease any negative impact & to enhance positive effect.

  10. Methodology • The research method will be involving formal and informal interviews with key informants within formal and indigenous organization. These included: • key government officials. • Environmental consultants. • Nongovernmental organizations. • Local leaders. • The questioning forms will be designed to identify constraints EIA carry out in the area. The relevant literature will be analyzed on the basis of themes and the research goal.

  11. The negative impacts of any activity on the environmental resources will then be evaluated, and the results will be examined.

  12. Out Comes • The study attempts to assess any issues/ problem related to dam site and future impacts on locality and to provide suggestive measures for the dam and improvement of the construction of the dam.
