This page provides access to documentation from ORASECOM endorsed projects in the Orange-Senqu River basin. The publications are organised by the different ICP support programmes.

This page also provides access to ORASECOM’s NEWSLETTERS. ORASECOM has issued its first newsletter covering the period January to December 2009. However, this issue also provides a brief background on the Orange-Senqu River Basin and ORASECOM’s projects being supported by the different International Cooperating Partners (ICPs). The newsletters can be accessed by clicking here.

Additional ORASECOM publications will be made available on this page as they are developed.

FGEF Support

The French Global Environment Facility (FGEF) provided support to strengthen the capacities and experience of ORASECOM, through the implementation of concrete actions by the establishment of project implementation unit (PIU) as an interim body until permanent secretariat for ORASECOM was in place. The PIU was to apply the principles of integrated water resources management (IWRM) in its supervision of project implementation. The support programme published a series of reports, summarising their activities.


In view of the existing and possible future developments that will influence the availability of water in the Orange River, the Orange River Integrated Water Resources Management Plan Phase I was developed. This programme has been followed by a second phase, which aims to develop a basin-wide integrated water resources management plan.


The Transboundary Diagnostic Analysis was completed in 2009 and is available to download from the UNDP website or from the ORASECOM website.


The European Union (EU) provides project support to ORASECOM aimed at institutional strengthening of ORASECOM and building the capacity of the organisation to deliver on its mandate.

Joint Water Resources Quality Survey (JBS)

ORASECOM will undertake a detailed assessment of the water resources quality state of the Orange Senqu River system in September / October/November 2010. This Joint Basin-wide Survey will provide the first broad understanding of the state of the aquatic ecosystems, Habitats, the presence of Persistent Organic Pollutants, and water quality at river sites throughout the Basin. The survey will learn from similar surveys conducted by the International Commission for the Protection of the Danube River (ICPDR). The proposed Orange-Senqu Joint Basin-wide Survey -1 (JBS-1) will set the baseline water resources quality for the system. The planning and execution of JBS-1 will be actively supported by all the Contracting Parties and the International Cooperating Partners (ICPs) i.e. UNDP-GEF, EU and GTZ(BMZ/UKaid). Two planning workshops have been held on the 24th of May 2010, and the 21st of September 2010, in Johannesburg, and Pretoria, South Africa, respectively.

With the support of the African Development Bank (AfDB), the New Partnership for Africa’s Development (NEPAD) and other Partners, from January 2017 to June 2020, ORASECOM is developing its climate resilient water resources investment stratety & plan, as well as undertaking a pre-feasibility study for the Lesotho-to-Botswana Water Transfer and a feasibility study for the proposed dam site on the Makhaleng River in Lesotho.
