FileOrange-Senqu River Basin: Preliminary Transboundary Diagnostic Analysis Executive Summary
Adopted by ORASECOM in April 2008
Orange-Senqu Preliminary TDA 1
Adopted by ORASECOM in April 2008 The GEF IW TDA/SAP “best practice” approach underpins the methodology used in the development of the Orange-Senqu River Basin TDA. Consequently the methodology for the TDA consists of the following steps: • Identification and initial prioritisation of transboundary problems • Gathering and interpreting information on environmental impacts and socio-economic consequences of each problem • Causal chain analysis (including root causes) • Completion of an analysis of institutions, laws, policies and projected investments. It focuses on transboundary problems without ignoring national concerns and priorities and identifies information gaps, policy distortions and institutional deficiencies. The analysis is cross-sectoral and examines national economic development plans, civil society (including private sector) awareness and participation, the regulatory and institutional framework and sectoral economic policies and practices. Causal Chain Analysis (CCA) is one of the most useful aspects of the TDA for the development of future corrective actions. The causal chain should relate the transboundary problems with their impacts, immediate physical causes and their social and economic underlying root causes.

FileCapacity Building Programme Report
An understanding of water resource management principles and policies is vital to the continued and sustainable management of any water resource. However, when the water resources are shared between different countries, the issues become even more complicated and require focused attention and management. In order to achieve sustainable water resource management it is vital that the key role-players and stakeholders are well versed with the legislation and respective policies and strategies of not only their own countries but also those of their partner states.

This report forms part of the final deliverables for the Feasibility Study for the Development of a Mechanism to Mobilize Funds for Catchment Conservation. This report is to be read in conjunction with the Business Case report which details the organisational/institutional and financial models for proposed ORASECOM Conservation Fund.
FileGroundwater Review of the Molopo-Nossob Basin for Rural Communities
The Molopo River is an ephemeral tributary of the Orange – Senqu River system, an international river basin shared by Lesotho, Namibia, Botswana and South Africa. The Orange-Senqu River Commission (ORASECOM) is established to advise the parties on water related issues. The size of the Molopo-Nossob Basin is approximately one and a half times the size of Great Britain, 12 times the size of Lesotho or almost equal to the size of Japan.
FileFeasibility Study of the Potential for Sustainable Water Resources Development in the Molopo-Nossob Watercourse
The Molopo River receives most of its flow from tributaries in the Republic of South Africa, most of which have now been dammed for irrigation in agriculture. As a result, inflow from these sources to the Molopo River, which forms the boundary between Botswana and South Africa, has become reduced and even non-existent in some years.
FileAssessment and Potential for the Development July 2009 and Use of “Marginal Waters”
Scarcity of water in semi-arid regions of the world, similar to the Orange-Senqu River Basin, has necessitated the development of strategies to optimise the use of available water resources. One of the most widely adopted measures is the augmentation of the water supply through the use of unconventional or “marginal” water sources. Marginal water can be used to supplement intensively exploited conventional sources.

FileLegislation and Legal Issues Surrounding the Orange River Catchment Report
The present report forms part of a broader study about the eventual development and adoption of an Integrated Water Resources Management Plan (IWRMP) for the Orange River. It deals with certain international agreements on shared water usage and with water-related legislation in the four states (Lesotho, South Africa, Botswana and Namibia) that are party to ORASECOM.
FileInstitutional Structures in the four Orange Basin States Report
The Orange-Senqu River originates in the Lesotho Highlands and flows westward for 2200km, to the Atlantic coast of South Africa and Namibia, forming the border between those two states. The Basin also encompasses the southern portion of Botswana. As such, there are four basin states that share the waters of the Orange-Senqu River Basin
FileReview of Existing Infrastructure in the Orange River Catchment
Several new developments have already been commissioned or have been identified as possible future demand centres for water along the Lower Orange River. In Namibia such developments include the Haib copper mine, Skorpion lead and zinc mine (already developed), the Kudu gas fired power station at Oranjemund and several irrigation projects for communal and commercial irrigation along the northern riverbank.
FileReview of Groundwater Resources in the Orange River Catchment Report
The Orange River Basin extends into four countries; Republic of Botswana, The Kingdom of Lesotho, the Republic of Namibia, and the Republic of South Africa. It includes the total land area of Lesotho, most of the central part of South Africa and reaches to the southern part of Botswana as well as draining most of the southern half of Namibia. The Orange- Senqu River Commission (ORASECOM) came into existence on 3rd November 2000 by agreement among the four basin member states in terms of the SADC Protocol on Shared Watercourse Systems, with one of the primary aims being the integrated development and management of the water resources of the Orange River to the mutual and equitable benefit of all parties.

FileCurrent Analytical Methods and Technical Capacity of the four Orange Basin States Report
In view of the existing and possible future developments which will influence the availability of water in the Orange River, a project has been initiated by ORASECOM and commissioned and funded by GTZ involving all four basin states (Botswana, Lesotho, Namibia and South Africa). The main objective of the project is to facilitate the development of an Integrated Water Resources Management Plan for the Orange River Basin.
