Politics and development that are indifferent to sustainability have come at profound cost to the River Ravi ecosystem. The previously rich ecosystem hosted 65 fish species and a myriad of other wildlife; most of which is gone. Much of the floodplain has been converted to farmland or urban development. The perennial and non-perennial tributaries are drains conveying wastewater from large urban centres to the River Ravi. And, in parts, the River Ravi itself can no longer sustain aquatic life throughout the year. The objectives of the River Ravi study are: To undertake a comprehensive current situation assessment of the river basin, including the pollution situation and its impacts on human and ecosystem health, climate change risks and vulnerabilities, institutional gaps and development needs; To summarise the outcomes as an ADB knowledge product that can be used to raise public awareness, foster policy engagement and generate support for the revitalization and resilience plan, and its subsequent implementation; To develop a long-term, multisector plan to revitalize and build resilience in the Ecosystem of River Ravi Basin, including recommendations for investment projects and institutional reforms, including: an analytical framework for the plan developed through multi-stakeholder visioning exercises and consultation and one or two prefeasibility studies will be prepared for identified priority projects.
The proposed approach was to make use of and build on work from the Zambezi Basin on behalf of ZAMCOM as part of the Zambezi Water Resources Information System (ZAMWIS) Enhancement 3 Project.The ZAMWIS approach to EFlows is to use existing DRIFT EFlows databases for the basin to establish relationships between driving hydrological and sediment indicators and responding ecosystem indicators.The idea is to use these to deliver a rapid EFlows assessment for the Kafue Flats and Kafue Gorge for use in ongoing planning initiatives by GFA in Zambia.
Collation of information pertinent to, and generation of Environmental Water Requirement (EWR) data for, the classification of rivers in the Berg River basin and calculation of Resource Quality Objectives (RQOs) for a monitoring programmes.

Generating a thorough understanding of the functional ecology of the Elephant Marshes incorporating hydromorphology, ecosystem services, biodiversity, and livelihoods; and model past, present, and future possible management strategies. The assignment will also assess the feasibility for designating the marshes as a community-managed protected area and as a wetland of international importance under the Ramsar convention using information from the surveys to assess whether the Elephant Marshes meet the Ramsar Criteria.
An elementary tool for Ecological Reserve monitoring in high-value conservation catchments in South Africa was developed.
To use a variety of data sources to compile a framework of change at temporal and spatial scales of relevance to river ecosystems, and to correlate these with known, and measured, changes in river ecosystem condition with the aim of identifying the long-term: (1) natural cycles; (2) non-flow related impacts and (3) flow related impacts on components of the rivers.
Preparation of management plans for the maintenance activities of riparian land owners along the Breede, Jan Du Toit, Hartebees, Hex, Noree/Vink, Klaasvoogds and Keisie Rivers.
Quantifying the links between patterns of riparian vegetation and flow on South African rivers. Current knowledge, existing data from Reserve studies, and empirical evidence was synthesized to propose a naming convention, methods of identification and a description of the characteristics of lateral zonation patterns in riparian vegetation communities.
