  • Foreign Policy in the Indus Basin: the Mangla
    INSTITUTE OF CURRENT WORLD AFFAIRS CM-6 Karachi Foreign Policy in the Indus Basin January 25, 196 The Mangla Dam Mr. Richard H. Nolte Institute of Current World Affairs 366 Madison Avenue New York 17, New York Dear Dick In 1960 the United States joined with Pakistan, India, four other states, and the World Bank to make contributions to the Indus Basin Development Fund. The total resources to be available were the equivalent of $894,000,000 of which amount 5 per cent was to come from U. S. sources.1 It s now estimated that the cost of the Indus Basin Development will reach $1.8 billion, more than double the original estimates -about par for the course. The expectation is that the United States in due course will ante up a 5 per cent share of the increased cost. The plan for development of the Indus Basin was formulated as a first step in a free world try to bring political peace to the Indian subcontinent. The separation of India and Pakistan in 1947 had been based on political lines drawn to separate the Muslims of Pakistan from the predominantly Hindu population of India. Geography was ignored. As a consequence, India acquired physical possession of the headwaters of three east-bank tributaries of the Indus River and asserted the right to divert those waters to its own use. This left some 1,000,O00 acres of Pakistan without a reliable source of water. The subsequent water dispute festered for a decade. It was finally terminated in 1960 by the Indus Waters Treaty between Pakistan and India, and by creation under World Bank auspices of the Indus Basin Development Fund.

  • Soil Erosion and Sediment Load Management Strategies for Sustainable Irrigation in Arid Regions
    sustainability Article Soil Erosion and Sediment Load Management Strategies for Sustainable Irrigation in Arid Regions Muhammad Tousif Bhatti 1,* , Muhammad Ashraf 2,* and Arif A. Anwar 1 1 International Water Management Institute, Lahore 53700, Pakistan; [email protected] 2 Department of Agricultural Engineering, Khwaja Fareed University of Engineering & Information Technology, Rahim Yar Khan 64200, Pakistan * Correspondence: [email protected] (M.T.B.); [email protected] (M.A.) Abstract: Soil erosion is a serious environmental issue in the Gomal River catchment shared by Pakistan and Afghanistan. The river segment between the Gomal Zam dam and a diversion barrage (~40 km) brings a huge load of sediments that negatively affects the downstream irrigation system, but the sediment sources have not been explored in detail in this sub-catchment. The analysis of flow and sediment data shows that the significant sediment yield is still contributing to the diversion barrage despite the Gomal Zam dam construction. However, the sediment share at the diversion barrage from the sub-catchment is much larger than its relative size. A spatial assessment of erosion rates in the sub-catchment with the revised universal soil loss equation (RUSLE) shows that most of −1 −1 the sub-catchment falls into very severe and catastrophic erosion rate categories (>100 t h y ). The sediment entry into the irrigation system can be managed both by limiting erosion in the catchment Citation: Bhatti, M.T.; Ashraf, M.; and trapping sediments into a hydraulic structure. The authors tested a scenario by improving Anwar, A.A. Soil Erosion and the crop management factor in RUSLE as a catchment management option.

  • Dams and Displacement in Turkey and Pakistan
    ISSN 2411-9571 (Print) European Journal of Economics May-August 2017 ISSN 2411-4073 (online) and Business Studies Volume 3, Issue 2 Dams and Displacement in Turkey and Pakistan Abdul Hadi Assistant Professor. Harran University, Faculty of Arts and Sciences, Department of Sociology, “Şanlıurfa” Turkey. Email: [email protected] & [email protected] Abstract The development policy makers in both Turkey and Pakistan believe that the construction of dams would bring development and prosperity in their countries. Believing in this development model, so far many dams have been constructed and others are either under the construction or in planning process in both countries. The evidences are steadily mounting and reveal that the benefits of dams have been over exaggerated and their social and ecological costs were grossly underestimated. Construction of dams resulted in the displacement of thousands of people in both countries. With the help of existing literature and studies, this study has focused on the living conditions of displacees after the construction of dams in both countries. This study has found that in the case of Turkey due to inequitable land distribution major benefits of dams mostly beneficiaries of dam projects are people who are already well-off and but the people who were displaced due to dams and also were landless are living worse life compared with their previous living conditions. In Pakistan, there were resettlements plans for reservoir-induced displacees but not for deltaic people who were the most affectees. The reduction in fresh water flow and the encroachment of sea have brought destruction to both delta and deltaic people.

Given their importance and the huge investment, assessments of current UIB sediment load and possible future changes are crucial for informed decisions on planning of optimal dams’ operation and ensuring their prolonged lifespan. In this regard, the daily suspended sediment loads (SSLs) and their changes are analyzed for the meltwater-dominated zone up to the Partab Bridge and the whole UIB up to Besham Qila, which is additionally influenced by monsoonal rainfall. The gaps between intermittent suspended sediment concentration (SSC) samples are filled by wavelet neural networks (WA-ANNs) using discharges for each site. The temporal dynamics of SSLs and discharges are analyzed using a suite of three non-parametric trend tests while the slope is identified using Sen’s slope estimator. We found disproportional spatio-temporal trends between SSLs and discharges caused primarily by intra-annual shifts in flows, which can lead to increased trap efficiency in planned reservoirs, especially upstream of Besham Qila.

  • Ordinal Classification of Vegetation Along Mangla Dam, Mirpur, Ajk
    Pak. J. Bot., 47(4): 1423-1428, 2015. ORDINAL CLASSIFICATION OF VEGETATION ALONG MANGLA DAM, MIRPUR, AJK RABAIL UROOJ1, SHEIKH SAEED AHMAD1*, MUHAMMAD NAUMAN AHMAD2 AND SARDAR KHAN3 1Department of Environmental Sciences, Fatima Jinnah Women University, Mall Road, Rawalpindi, Pakistan 2Department of Agricultural Chemistry, University of Agriculture, Peshawar, Pakistan 3Department of Environmental Sciences, University of Peshawar, Pakistan *Corresponding author’s e-mail: [email protected], 92 321 5167726 Abstract Vegetation plays an important role in ecosystem maintenance. But the construction of dams transform the riparian vegetation into impoundment region. The present study was conducted to identify and quantify herbaceous flora around the vicinity of Mangla dam. Study area was divided into two zones on the basis of distance from the dam boundary. Pattern of vegetation distribution and their association in area was grouped in to different communities by using ordination techniques. Two ordination techniques TWINSPAN and DECORANA were used. A total of 37 species belonging to 17 families were identified from fifty quadrats. Random sampling was done by using 1 ×1 m sized quadrat. Percentage of vegetation was assessed by using Domin cover scale. TWINSPAN classified two groups and four communities in Zone-I, while in Zone-II two groups and six communities were formed. Dominance curve showed that Cynodon dactylon, Desmostachya bipinnata and Rhynchosia minima were dominant species in Zone-I and Croton bonplandianus, C. dactylon, D. bipinnata and Brachiaria decumbens were frequent species in Zone-II. DCA as indirect multivariate technique based on reciprocal averaging determined the environmental gradients that affect the species richness and also verified the groups of species and indicated four communities in both Zones.
