The governments of Malawi, Tanzania, and Mozambique signed a Memorandum of Understanding for the joint management and development of the Ruvuma/Rovuma River Basin, a transboundary river basin traversing across the three SADC member states. Ministers of Water from the three member states; Hon. Abida Mia from Malawi, Hon...
The river serves as a vital water source for communities, agriculture, and industries across the three member states, but despite its benefits, the basin faces several challenges that include a lack of comprehensive management plans, hampering the sustainable use and conservation of its resources. The basin is also inc...
To address these challenges, the Ruvuma Basin member states, with support and collaboration from the Southern African Development Community (SADC), the International Union for Conservation of Nature (IUCN) as implementing authorities, and the Global Water Partnership Southern Africa (GWPSA), as the executing agency, ar...
“The MoU will serve two main objectives; to develop mechanisms for corporation on sustainable use, development, protection, conservation, and management of the Ruvuma Basin and strengthen cooperation; and establish an interim secretariat for the Ruvuma River Basin Commission,” reads part of the MoU.
The Ruvuma River Basin covers an area of approximately 155,000 km2, with the Mozambican territory covering 100,000 km2 (65%), Tanzania covering 52,000 km2 (~34%), while the remaining part is in Malawi covering 2,500 km2 (<2%).
Ministers responsible for water from Tanzania, Malawi and Mozambique signed the Joint Management Ruvuma/Rovuma River Basin MoU in Dar es Salaam, Tanzania on 31 July 2024
With the signed MoU, the three SADC member states will cooperate on the following areas, among others:
Promote equitable utilisation, efficient management, and sustainable development of the water resources
Promote research in the area of integrated and sustainable management and development of the basin
Build capacity of the institutions that contribute to the implementation of the MoU
Strengthen monitoring of both the quality and quantity of the water resources and environmental changes in the basin
Promote information and data sharing including environmental and social impact assessment results.
The three states already conducted stakeholder engagement exercises, which helped identify the major challenges around the basins and the potential solutions. In Malawi for instance, stakeholders suggested several interventions, including the following:
Basin-wide awareness campaign:
Launch a comprehensive campaign across the basin to raise awareness among all stakeholders, including political leaders, communities, and water-related sectors to emphasize the significance of water resource management and environmental protection, highlighting the importance of sustainable practices. The campaign will...
Provision of education and training:
Revamp and establish all community water resources and environmental management committees within the basin and provide training and education to enhance sustainable management of water and the environment.
Promotion of alternative livelihoods:
Introduce sustainable income-generating activities for communities residing near protected areas to deter unsustainable resource usage and promote income generation.
Strengthening of multi-stakeholder platforms:
Strengthen capacity and operationalise the existing basin-wide service providers and institutions in environmental management and water resources management, including fisheries.
Promotion of sustainable agriculture:
Encourage the adoption of sustainable agricultural practices, like conservation agriculture to mitigate the adverse effects of unregulated shifting cultivation.
Environmental restoration:
Rehabilitate degraded areas through enrichment planting.

Global Transboundary Water Governance Corpus

A curated, openly available corpus of 252 official policy, legal, and institutional documents that govern internationally shared waters (rivers, lakes, and aquifers), released with full extracted text and harmonised structured metadata.

Coverage: 123 river basins, lake systems, and hydrological regions; 141 sovereign states as parties; 14 languages; documents published 1909–2025.
Content types: treaties, agreements, conventions, protocols, national laws, strategies, action plans, and framework documents issued by governments, intergovernmental organisations, basin authorities, and United Nations agencies.
Size: ~59 million characters of clean UTF-8 text. 233 records hold the full document body; 19 are landing- or press-page text only (flagged via source.status).

This deposit accompanies a Data in Brief data article that describes it in full.

Repository structure

corpus/               252 UTF-8 text files, one per document, named <NN>-slug.txt
documents.json        252 metadata records (one JSON object per document)
corpus_summary.csv    flat one-row-per-document table of the core metadata
fetch_corpus.py       retrieval + text-extraction script that builds the corpus
README.md             this file (dataset card + data dictionary)

The <NN> prefix is a permanent document number, stable across releases and referenced by source.text_path in the metadata.

How the corpus was built

Documents were assembled by an AI-assisted retrieval protocol (query diversification and deduplication) over official and open-access legal, treaty, government, and basin-commission sources, followed by text extraction (pypdf for PDF, Beautiful Soup for HTML, OCR for scanned PDFs, and the Internet Archive Wayback Machine for relocated or blocked links). Every candidate was verified by human reviewers, and every text snapshot is frozen with a SHA-256 hash for reproducibility. Full details are in the accompanying data article.
