Transboundary Diagnostic Analyses
Transboundary Diagnostic Analyses are science-based analyses of transboundary water-related concerns and opportunities that exist in multi-country surface water, ground water, and coastal/marine water systems. They are used to identify priorities for joint action, root causes and scope for the concerns or opportunities, and serve as the basis for reforms and investments included in the action programmes.

ASCLME/SWIOFP TDA Vol 1
- The Agulhas and Somali Current Large Marine Ecosystems (ASCLME) Project and the South West Indian Ocean Fisheries Project (SWIOFP) are part of a multi-project and multi-agency undertaking to institutionalize cooperative and adaptive management of the Agulhas and Somali LMEs. South Africa, Mozambique, Tanzania, Kenya, Comoros, Seychelles, Madagascar and Mauritius are full participants in both Project activities while Somalia has observer status. France is a full participant in the SWIOF Project and an active partner in the ASCLME Project. This Transboundary Diagnostic Analysis (TDA) has been developed jointly by the ASCLME and SWIOF Projects and is the regional synthesis report on the current status of the Agulhas and Somali Current Large Marine Ecosystems. It presents an analysis of the ecosystem status and the threats to the long term sustainability of coastal and marine processes and resources in the region. The relative importance of the immediate and root sources and causes of the problems are assessed with a view to identifying potential preventive and remedial actions. As such, the TDA provides the technical basis for development of a Strategic Action Programme (SAP) for the region. The TDA is based on the outcomes of a four-year process of data collection, regional reviews and assessments, and engagement with stakeholders in the ASCLME countries from community to ministerial level. The input to the Analysis comes from the National Marine Ecosystem Diagnostic Analyses (MEDAs) together with a total of 56 reports and studies resulting from detailed specialist studies undertaken by the projects.

Nubian Shared Aquifer Diagnostic Analysis (SADA)
- Represents the technical data-gathering element of the GEF Medium Size Project to strengthen cooperative management of the Nubian Sandstone Aquifer System (NSAS) in the Libyan Arab Jamahiriya (Libya), Egypt, Chad, and Sudan. The SADA is process through which transboundary threats are identified and prioritized with the specific purpose of informing the Strategic Action Program (SAP) phase of the project.

Volta Basin TDA-English
- In line with international best practices, to address environmental and social concerns in the basin, the GEF Volta project in collaboration with the Volta Basin Authority launched the process to prepare this Trans-boundary Diagnostic Analysis (TDA) and the subsequent Strategic Action Programme (SAP). The TDA is to provide a participatory and science-based assessment of the Volta River Basin, the threats to the basin’s resources, and the causes underlying those threats. The TDA builds on the earlier preliminary TDA. It uses updated information and analysis, and follows recent international guidance on Trans-boundary Diagnostic methodologies. The TDA provides a mechanism for improved and collaborative decision-making at the regional level. Notably, it forms the sound basis for the SAP.

BOBLME TDA Volume 2
- Volume 2 contains background material that sets out the biophysical and socio-economic characteristics of the BOBLME; an analysis of the legal, policy and administrative context in the eight countries that border the Bay of Bengal; and an assessment of the status of marine living resources and the marine environment in the coastal areas of the BOBLME.
-
BOBLME TDA Volume 1
- This document was prepared after the Transboundary Diagnostic Analysis (TDA) Confirmation Workshop held in Phuket Thailand from 13 to 14 February 2012. The TDA is published in two volumes. Volume 1 describes the transboundary issues in the Bay of Bengal Large Marine Ecosystem (BOBLME) and their proximate and underlying root causes. These will be used to develop a Strategic Action Programme (SAP).
-
BOBLME TDA Executive Summary
- The eight Bay of Bengal countries have determined three major problems (or areas of concern) affecting the health of the Bay, that they can work on together.

Transboundary Diagnostic Analysis of the Lake Chad Basin
- DR HASSAN HARUNA BDLIYA, FEDERAL MINISTRY OF ENVIRONMENT AND HOUSING FEDERAL SECRETARIAT MAITAMA, ABUJA AND DR MARTIN BLOXOM This Transboundary Diagnostic Analysis, a key output of the the LCBC-GEF programme, is centred on the transboundary environmental problems that need to be addressed jointly by the international community and the LCBC member states, if the degradation trends are to be reversed. The analysis is intended to form the basis for the preparation of a strategic action program (SAP) for the LCB. It was also done in fulfilment of a requirement for most projects intended to be financed from the GEF International Waters Focal Area, from which support for the implementation of the proposed SAP will be sought by the LCBC
