A Silent Crisis in Congo: the Bantu and the Twa in Tanganyika
CONFLICT SPOTLIGHT A Silent Crisis in Congo: The Bantu and the Twa in Tanganyika Prepared by Geoffroy Groleau, Senior Technical Advisor, Governance Technical Unit The Democratic Republic of Congo (DRC), with 920,000 new Bantus and Twas participating in a displacements related to conflict and violence in 2016, surpassed Syria as community 1 meeting held the country generating the largest new population movements. Those during March 2016 in Kabeke, located displacements were the result of enduring violence in North and South in Manono territory Kivu, but also of rapidly escalating conflicts in the Kasaï and Tanganyika in Tanganyika. The meeting was held provinces that continue unabated. In order to promote a better to nominate a Baraza (or peace understanding of the drivers of the silent and neglected crisis in DRC, this committee), a council of elders Conflict Spotlight focuses on the inter-ethnic conflict between the Bantu composed of seven and the Twa ethnic groups in Tanganyika. This conflict illustrates how representatives from each marginalization of the Twa minority group due to a combination of limited community. access to resources, exclusion from local decision-making and systematic Photo: Sonia Rolley/RFI discrimination, can result in large-scale violence and displacement. Moreover, this document provides actionable recommendations for conflict transformation and resolution. 1 http://www.internal-displacement.org/global-report/grid2017/pdfs/2017-GRID-DRC-spotlight.pdf From Harm To Home | Rescue.org CONFLICT SPOTLIGHT ⎯ A Silent Crisis in Congo: The Bantu and the Twa in Tanganyika 2 1. OVERVIEW Since mid-2016, inter-ethnic violence between the Bantu and the Twa ethnic groups has reached an acute phase, and is now affecting five of the six territories in a province of roughly 2.5 million people. -

Ramsar Information Sheet
Ramsar Information Sheet Text copy-typed from the original document. 1. Date this sheet was completed: 20.11.1996 2. Country: Botswana 3. Name of wetland: The Okavango Delta System 4. Geographical co-ordinates: The Okavango Delta System lies between Longitudes 21 degrees 45 minutes East and 23 degrees 53 minutes East; and Latitudes 18 degrees 15 minutes South and 20 degrees 45 minutes South. It includes the Okavango River, commonly referred to as the Pan handle; the entire Okavango Delta; Lake Ngami; and parts of the Kwando and Linyanti River systems that fall west of the western boundary of the Chobe National Park. The entire area is as depicted on the attached map. 5. Altitude: Generally between 930 metres and 1000 metres above sea level. 6. Area: Approximately 68 640 km² (6 864 000 hectares) 7. Overview Three main features characterise the region, the Okavango, the Kwando and Linyanti river system connected to the Okavango Delta through the Selinda spillway and the intervening and surrounding dryland areas. These features are located within the Okavango rift, a geological structure subject to tectonis control and infilled with Kahalari Group sediments, principally sand, up to 300 metres thick. The Delta is the most important of the above named features. It is an inland delta in a semi arid region in which inflow fluctuations result in large fluctuations in flooded area (10,000 - 16,000 km²), which is comprised of permanent swamp, seasonal swamp and intermittently flooded areas. Similar flooding takes place in the Kwando/Linyanti river system. This leads to high seasonal concentrations of birdlife and wildlife, giving the area a very high tourism potential. -
Overview of Experiences in the Limpopo River Basin
intersectorai Management of River Basins Overview of Experiences in the Limpopo River Basin Thomas Schild Team Leader, German Agency for Technical Co-operation (GTZ), Windhoek, Namibia Abstract The paper presents a summary of the findings of a German mission to four countries of Southern Africa, in which many people at different levels were asked to give their views about water issues in two trans-national river basins, the Limpopo and the Orange-Senqu. The principal common factors in people's responses are identified. Various sources and types of inequity are described. In conclusion, it is found that external assistance could be especially useful in areas of information and communication, and in organisational development for river-basin management. 1. Context A mission by a project appraisal team of the German Agency for Technical Co operation (GTZ) was carried out in September 2000, for the support of regional water management in the SADC (Southern African Development Community) region. The team talked to stakeholders of the Limpopo and the Orange-Senqu river basins. The mission had the following major tasks; Map the scene; Capture the expectations and issues of concern of the stakeholders with regard to the establishment of river basin commissions; Identify possible areas for technical co-operation; Make preparations for the planning workshop. 2. Procedures Between 14 and 29 September 2000, the group visited Zimbabwe, Mozambique, Botswana and South Africa and held discussions with relevant government institutions, parastatals and donor organisations involved in water resources management of the Limpopo and, where applicable, of the Orange/Senqu. Other resource persons, such as representatives of water users' organisations, researchers, non-governmental organisations (NGOs) and consultants were met. -

Masija Irrigation Department Ministry of Agriculture, Livestock and Cooperatives P.O. Box 9192 Dar es Salaam Summary Over 1,164,000 ha of wetland areas are listed as suitable for irrigation, mainly for crop production and livestock grazing. Existing and planned irrigation schemes are described for the ,main river basins where large areas are devoted to rice and sugar cane. Emphasis' is placed on the value of small scale, farmer-managed irrigation schemes and the rehabilitation of traditional systems. Introduction All wetlands are potentially suitable for agriculture because of their available water and high soil fertility. Due to national priorities or requirements some wetlands are put to other uses, such as game reserves. The total wetland area identified as suitable for irrigation development is estimated to be over 1,164,600 ha (Table 1). Wetlands are swamps or low lying areas of land which are subject to inundation, usually seasonally. They have hydromorphic soils, transitional morphological characteristics between terrestrial and aquatic ecosystems, and support hydrophytes and halophytes. Wetlands in Tanzania can be characterised under four main categories: 1. Deltaic processes of rivers which discharge into the Indian Ocean and are characterised by flat topography, low lying relief and heavy'clay soils. They are subject to sea water intrusion which contributes to the salinisation of the soils which, under predominantly mangrove vegetation, are potentially acid sulphate. -
Large Hydro-Electricity and Hydro-Agricultural Schemes in Africa
FAO AQUASTAT Dams Africa – 070524 DAMS AND AGRICULTURE IN AFRICA Prepared by the AQUASTAT Programme May 2007 Water Development and Management Unit (NRLW) Land and Water Division (NRL) Food and Agriculture Organization of the United Nations (FAO) Dams According to ICOLD (International Commission on Large Dams), a large dam is a dam with the height of 15 m or more from the foundation. If dams are 5-15 metres high and have a reservoir volume of more than three million m3, they are also classified as large dams. Using this definition, there are more than 45 000 large dams around the world, almost half of them in China. Most of them were built in the 20th century to meet the constantly growing demand for water and electricity. Hydropower supplies 2.2% of the world’s energy and 19% of the world’s electricity needs and in 24 countries, including Brazil, Zambia and Norway, hydropower covers more than 90% of national electricity supply. Half of the world’s large dams were built exclusively or primarily for irrigation, and an estimated 30-40% of the 277 million hectares of irrigated lands worldwide rely on dams. As such, dams are estimated to contribute to 12-16% of world food production. Regional inventories include almost 1 300 large and medium-size dams in Africa, 40% of which are located in South Africa (517) (Figure 1). Most of these were constructed during the past 30 years, coinciding with rising demands for water from growing populations. Information on dam height is only available for about 600 dams and of these 550 dams have a height of more than 15 m. -

This model allows us to track atmospheric parcels while calculating changes in the specific humidity through the budget of evaporation-minus-precipitation. The method permitted the identification at an annual scale of five continental and four oceanic regions that provide moisture to the CRB from both hemispheres over the course of the year. The most important is the CRB itself, providing more than 50% of the total atmospheric moisture income to the basin. Apart 15 from this, both the land extension to the east of the CRB together with the ocean located in the eastern equatorial South Atlantic Ocean are also very important sources, while the Red Sea source is merely important in the budget of (E-P) over the CRB, despite its high evaporation rate. -

Box MP600, Mount Pleasant, Harare, Zimbabwe Correspondence: Colleta Tundu ([email protected]) Received: 7 June 2017 – Accepted: 10 October 2017 – Published: 16 April 2018 Abstract. Sediment delivery into water sources and bodies results in the reduction of water quantity and quality, increasing costs of water purification whilst reducing the available water for various other uses. The paper gives an analysis of sedimentation in one of Zimbabwe’s seven rivers, the Mazowe Catchment, and its impact on water quality. The Revised Universal Soil Loss Equation (RUSLE) model was used to compute soil lost from the catchment as a result of soil erosion. The model was used in conjunction with GIS remotely sensed data and limited ground observations. The estimated annual soil loss in the catchment indicates soil loss ranging from 0 to 65 t ha yr−1. Bathymetric survey at Chimhanda Dam showed that the capacity of the dam had reduced by 39 % as a result of sedimentation and the annual sediment deposition into Chimhanda Dam was estimated to be 330 t with a specific yield of 226 t km−2 yr−1. -
