INF5 Draft Handbook on Water Allocation in a Transboundary ECE/MP.WAT/WG.1/2021/INF.5-ECE/MP.WAT/WG.2/2021/INF.5 Convention on the Protection and Use of Transboundary Watercourses and International Lakes Working Group on Integrated Water Resources Management Sixteenth meeting Working Group on Monitoring and Assessment Sixteenth meeting Geneva, 26 April–28 April 2021 Item 7 (b) of the provisional agenda Supporting equitable and sustainable water allocation in a transboundary context Draft handbook on water allocation in a transboundary context Prepared by the secretariat in cooperation with the lead Party Summary At its eight session (Nur-Sultan, 10-12 October 2021), the Meeting of the Parties to the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) decided to develop a handbook on transboundary water allocation, based on existing practices covering the key aspects of equitable and sustainable allocation of water in the transboundary context, addressing both surface waters and groundwaters, and also environmental flows (programme area 3, activity 3.3). The development of the Handbook started in 2019 and has been supported by an Expert Group of approximately 40 experts in water allocation from across the world seeking balanced geographical, sectoral and technical representation from countries, river basin organisations, inter-governmental organisations, non-government organisations, academic etc. The Group has provided guidance and oversight on the structure, substantive content and illustrative case studies. The Group met three times (Geneva, 21 October 2019, and virtually on 30-31 March and 20-21 October 2020) and was consulted throughout the development process in order to suggest structural and substantive elements, review drafted content and provide feedback. An annotated outline of the handbook on water allocation in a transboundary context (ECE/MP.WAT/WG.1/2020/INF.5) was presented at the fifteenth meeting of the Working Group on Integrated Water Resources Management (Geneva, 30 September–2 October 2020). The present document contains the first full draft of the handbook. Its main messages (see part III) are also presented in the official document entitled “Main messages of the draft handbook on water allocation in a transboundary context” (ECE/MP.WAT/WG.1/2021/7−ECE/MP.WAT/WG.2/2021/7). Illustrative case studies from around the world have been selected to highlight diverse transboundary allocation practices, challenges and lessons learned. Transboundary case studies are a unique feature of the Handbook. Many have 1 ECE/MP.WAT/WG.1/2021/INF.5-ECE/MP.WAT/WG.2/2021/INF.5 been developed and/or are in the process of being reviewed by representatives of the relevant riparian states, river basin organisations and any other relevant parties as part of the drafting process. A number of regional events and sessions in transboundary water cooperation workshops have been held to discuss the Handbook, including relevant case studies, and gain feedback. A dedicated session on water allocation was held in the ‘Regional workshop: Enhancing transboundary water cooperation in the MENA region: progress, challenges and opportunities’ on 3-4 March 2020 in Beirut, Lebanon. A virtual ‘Regional workshop on equitable and sustainable water allocation – Sharing experiences on transboundary water allocation and water scarcity’ focused on European Union countries, the Balkans, the Caucasus and Eastern Europe was held on 5-6 October 2020. A parallel regional project on transboundary water allocation, covering 10 countries in and around Central Asia, was implemented by the International Water Assessment Centre in Kazakhstan with key outcomes and selected case studies linked directly to the global Handbook for integration where appropriate. As part of this process, the following meetings were held: a ‘Technical meeting of experts on water allocation and environmental flow Assessment in the transboundary context’ (Nur-Sultan, 12-13 December 2019); a virtual online ‘E-Meeting of Experts on Water Allocation and Environmental Flow Assessment’ (15 May 2020); and a virtual online ‘Regional meeting on water allocation and environmental flow assessment in a transboundary context’ (22-23 September 2020). The Working Group on Integrated Water Resources Management and the Working Group on Monitoring and Assessment will be informed about the aim and contents of the draft Handbook, status of its preparation and the next steps in finalising the draft Handbook for submission to the ninth Meeting of the Parties, including the deadline for submitting feedback on the draft Handbook (21 May 2021). The Working Groups are invited to review and comment on the text in the present document including the “Main messages of the draft handbook on water allocation in a transboundary context” presented in official document ECE/MP.WAT/WG.1/2021/7−ECE/MP.WAT/WG.2/2021/7. The Working Groups are then invited to entrust the secretariat, in consultation with the lead country Hungary and the Expert Group, with the task of integrating comments, editing and finalizing the main messages and the full draft of the handbook on water allocation in a transboundary context, and preparing the final version for adoption at the ninth session of the Meeting of the Parties to the Water Convention (29 September–1 October 2021). 2 ECE/MP.WAT/WG.1/2021/INF.5-ECE/MP.WAT/WG.2/2021/INF.5 DRAFT HANDBOOK FOR REVIEW & FEEDBACK DEADLINE FOR FEEDBACK • 21 May 2021 LANGUAGE VERSIONS • The draft Handbook is currently available in English. • The draft Handbook is in the process of being translated into French, Russian and Spanish.

It sets up the Handbook by interrogating the central question: why and how is water allocation applied in transboundary basins, including surface and groundwater? The role, relevance, aims and limitations of allocation under changing circumstances and finite water resources are outlined. Finally, the Handbook’s purpose, audience, process of development under the Water Convention, content and usability are also described. 1) Water Allocation in a Transboundary Context A) Water Allocation across Borders in an Era of Changing Circumstances The question of how freshwater resources are allocated is becoming of increasing relevance to water managers today. Demand for water is growing globally. Factors including population growth, economic development and changing consumption patterns are driving this demand. At the same time, availability of water is increasingly limited by growing pressures such as water scarcity, deteriorating water quality, ecosystem degradation and climate change that further exacerbates the situation in many already water-stressed basins.1 Reserving water for environmental flow, Indigenous groups and ecosystem requirements is increasingly seen as a prerequisite for overall viability of water resources systems.2 The question of allocation is especially heightened in transboundary contexts. Over 60% of freshwater resources globally cross national boundaries, including 310 transboundary rivers and 592 transboundary aquifers.3 Many of these shared basins are vulnerable to the effects of climate change and other growing pressures. Water scarcity, contested infrastructure developments such as hydropower dams and increasing demand for, and competition over, shared water resources are all separate, but often interlinked, factors that have been leading to growing tensions in transboundary basins around the world. Where adaptivity of the existing water management arrangements is low, this can exacerbate any issues. In turn, this can compound the difficulties of states reaching peaceful settlements on water sharing in both the short, medium and long- term future.4 Many of the current transboundary water allocation regimes rely on historical usage patterns. Some may require adjustment in light of changing circumstances. In parallel, establishing new allocation arrangements 1 UNESCO, UN-Water, 2020: United Nations World Water Development Report 2020:Water and Climate Change, Paris, UNESCO.

  • Coping with Floods – the Experience of Mozambique1
    1st WARFSA/WaterNet Symposium: Sustainable Use of Water Resources, Maputo, 1-2 November 2000 COPING WITH FLOODS – THE EXPERIENCE OF MOZAMBIQUE1 Álvaro CARMO VAZ Professor, Faculty of Engineering, Eduardo Mondlane University Director, CONSULTEC – Consultores Associados Lda. e-mail: [email protected] ABSTRACT A summary review is made of the major floods that have occurred in Mozambique since the Independence in 1975, describing the most important negative impacts and consequences. Various types of measures for flood mitigation are analysed, considering how they have been used in past floods and their potential for coping with floods in the future. These measures are grouped into structural (dams, levees, flooding areas, river training) and non-structural measures (flood zoning, flood management, flood warning systems, emergency plans, raising awareness, insurance). The paper briefly refers the need for adequate and comprehensive reports on past floods and some related research areas. 1 THE FLOOD PRONE RIVERS OF MOZAMBIQUE More than 50% of the Mozambican territory is part of international river basins – from South to North, the Maputo, Umbeluzi, Incomati, Limpopo, Save, Buzi, Pungoé, Zambezi and Rovuma, see figures 1 and 2. All these rivers have their flood plains inside Mozambique, with the exception of the Rovuma river that forms the border between this country and Tanzania. The largest basins are the Zambezi (1,200,000 Km2) and the Limpopo (412,000 Km2) and the smallest one is the Umbeluzi (5,600 Km2) with the others ranging from about 30,000 to 150,000 Km2. The climatic conditions of Mozambique indicate that the country is subject to various types of events that can originate floods: cyclones and tropical depressions from the Indian Ocean and cold fronts from the south.

SALMAN M.A. SALMAN* Legal Regime for Use and Protection of International Watercourses in the Southern African Region: Evolution and Context ABSTRACT Water resources management is receiving increased attention worldwide due to the growing realization that most areas of the world face major challenges with regard to the quantitativeand qualitative aspects of water. These challenges are attributed to a multitude offactors, the most important of which are the signifi- cant increase in population, urbanization, and environmental d adation. Such factors are more apparent in the Southern Afican Region than in many other parts of the world. The region is, by and large,arid and semi-aridand as a resultfaces a shortage of water in many areas. Moreover, the high rates of population growth and urbanization threaten to worsen the situation. The region depends, to a large extent, on the waters of river basins, most of which are shared by two or more countries.

  • Southern Africa • Floods Regional Update # 1 10 March 2010 This Report Was Issued by the Regional Office for Southern and Eastern Africa (ROSEA)
    Southern Africa • Floods Regional Update # 1 10 March 2010 This report was issued by the Regional Office for Southern and Eastern Africa (ROSEA). It covers the period from 01 February to 9 March 2010. The next report will be issued within the next two weeks I. HIGHLIGHTS/KEY PRIORITIES • Normal to above normal rains in northern Zambia and northern Mozambique are causing river levels to rise, forcing authorities to discharge water from Kariba dam in Zimbabwe and Cahora Bassa dam in Mozambique. This, in addition to the ongoing rainfall is causing localized flooding in some areas. • The Government of Mozambique issued a Red Alert on 9 March, in response to the localized flooding in parts of the country. To date, 13,000 displaced people have been relocated to safe areas. • In Zambia, an estimated 800 families have been affected by flooding of which 150 have been relocated to temporary shelter setup by the Government. • An estimated 910 cholera cases and 19 cholera related deaths have been reported in Zambia. II. Regional Situation Overview Consistent with the SADC Outlook for the first quarter of the year, there has been normal to above normal rainfall across the northern half of southern Africa. Northern Zambia and northern Mozambique have particularly received above normal rains. In turn, the Kariba dam, in Zimbabwe, is 73% full. This prompted the opening of one flood gate on the 9th of March 2010. Eastern and Northern Zimbabwe received heavy rains in the past two weeks leading to flash floods in some areas and to the rise, above alert levels, of the Pungwe River downstream in Mozambique.

  • The Distribution of African Freshwater Fishes Répartition Des Poissons D’Eau Douce Africains
    65 Chapitre 4 THE DISTRIBUTION OF AFRICAN FRESHWATER FISHES RÉPARTITION DES POISSONS D’EAU DOUCE AFRICAINS P.H. Skelton The distribution of fishes in the rivers;lakes and other waterbodies of Afiica has always been of great interest to naturalists, scientists, ichthyologists and others involved with the Afiican fauna. By the second half of the 19th Century sufficient knowledge on the distribution of Af?i- cari freshwater fishes was at hand to provoke a few general comments by Günther (1880). Sys- tematic knowledge increased rapidly after this and by the tum of the Century Boulenger (1905) presented the first detailed synthesis of the distribution of Afiican freshwater fishes. This was followed by Pellegrin’s (1912) account before Boulenger’s (1909-l 915) classic Catalogue appea- red and set the stage for the surge of systematic literature on these fishes over the past sixty years or SO.Much of thishterature has dealt with the fauna of particular rivers, lakes or regions SOthat the broad details of’Xiican fish distribution are now known. Pol1 (1973) and Roberts (1975) have summarized and discussed this distribution on a pan Afiican scale. This chapter presents a systematic summary of present knowledge of distribution of fishes in the continenal waters of Afiica. Attention is focussed on families, with noteworthy generic and specific examples being mentioned. No attempt is made to provide a biogeographical analysis as this requires detailed knowledge of both the phyletic relationships of the taxa and the ove- .rall geological and geographical history of the continent (Greenwood, 1983). Furthermore, cur- rent biogeographical analyses demand pattem analysis incorporating different plant and animal groups, information which is not easily available at present.
