Regional Sources of Precipitation in the Ethiopian Highlands Regionala Källor Till Nederbörden I Det Etiopiska Höglandet
Independent Project at the Department of Earth Sciences Självständigt arbete vid Institutionen för geovetenskaper 2015: 2 Regional Sources of Precipitation in the Ethiopian Highlands Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz DEPARTMENT OF EARTH SCIENCES INSTITUTIONEN FÖR GEOVETENSKAPER Independent Project at the Department of Earth Sciences Självständigt arbete vid Institutionen för geovetenskaper 2015: 2 Regional Sources of Precipitation in the Ethiopian Highlands Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz Copyright © Elnaz Ashkriz and the Department of Earth Sciences, Uppsala University Published at Department of Earth Sciences, Uppsala University (www.geo.uu.se), Uppsala, 2015 Sammanfattning Regionala källor till nederbörden i det Etiopiska höglandet Elnaz Ashkriz Denna uppsats undersöker ursprunget till den stora mängd nederbörd som faller i det etiopiska höglandet. Med Moisture transport into the Ethiopian Highlands av Ellen Viste och Asgeir Sorteberg (2011) som grund syftar denna uppsats till att jämföra samma data men genom att titta på ett mycket kortare intervall för att se vad som försummas när undersökningar på större skalor utförs. Medan undersökningen av Viste och Sorteberg (2011) fokuserar på de två regnrikaste månaderna, juli och augusti under elva år, 1998-2008, så fokuserar denna uppsats enbart på juli år 2008. Syftet med denna uppsats var att se vart nederbörden till det Etiopiska höglandet kommer ifrån under juli månad 2008. För att undersöka detta så har man valt att titta på parametrar såsom horisontell- och vertikal vindriktning på olika höjder samt fukt- innehållet i dessa vindar. Som grund för undersökningen så har denna uppsats, likt Vistes och Sortebergs, använt ERA-Interim data. -

Empty Forests, Empty Stomachs? Bushmeat and Livelihoods in the Congo and Amazon Basins
International Forestry Review Vol.13(3), 2011 355 Empty forests, empty stomachs? Bushmeat and livelihoods in the Congo and Amazon Basins R. NASI1, A. TABER1 and N. VAN VLIET2 1Center for International Forestry Research (CIFOR), Jalan CIFOR, Situ Gede, Sindang Barang, Bogor 16680, Indonesia 2Department of Geography and Geology, University of Copenhagen, Oster Voldgade 10, 1350 Copenhagen K, Denmark Email: [email protected], [email protected] and [email protected] SUMMARY Protein from forest wildlife is crucial to rural food security and livelihoods across the tropics. The harvest of animals such as tapir, duikers, deer, pigs, peccaries, primates and larger rodents, birds and reptiles provides benefits to local people worth millions of US$ annually and represents around 6 million tonnes of animals extracted yearly. Vulnerability to hunting varies, with some species sustaining populations in heavily hunted secondary habitats, while others require intact forests with minimal harvesting to maintain healthy populations. Some species or groups have been characterized as ecosystem engineers and ecological keystone species. They affect plant distribution and structure ecosystems, through seed dispersal and predation, grazing, browsing, rooting and other mechanisms. Global attention has been drawn to their loss through debates regarding bushmeat, the “empty forest” syndrome and their ecological importance. However, information on the harvest remains fragmentary, along with understanding of ecological, socioeconomic and cultural dimensions. Here we assess the consequences, both for ecosystems and local livelihoods, of the loss of these species in the Amazon and Congo basins. Keywords: bushmeat, livelihoods, forest, Amazon, Congo Forêts vides, estomacs vides? Viande de brousse et condition de vie dans les bassins du Congo et de l’Amazone. -

Region: West Africa (14 Countries) (Benin, Burkina Faso, Cameroon, Chad, Côte d’Ivoire, Gambia, Ghana, Guinea, Guinea Bissau, Mali, Niger, Senegal, Togo) Project title: Emergency assistance for early detection and prevention of avian influenza in Western Africa Project number: TCP/RAF/3016 (E) Starting date: November 2005 Completion date: April 2007 Government counterpart Ministries of Agriculture responsible for project execution: FAO contribution: US$ 400 000 Signed: ..................................... Signed: ........................................ (on behalf of Government) Jacques Diouf Director-General (on behalf of FAO) Date of signature: ..................... Date of signature: ........................ I. BACKGROUND AND JUSTIFICATION In line with the FAO/World Organization for Animal Health (OIE) Global Strategy for the Progressive Control of Highly Pathogenic Avian Influenza (HPAI), this project has been developed to provide support to the regional grouping of West African countries to strengthen emergency preparedness against the eventuality of HPAI being introduced into this currently free area. There is growing evidence that the avian influenza, which has been responsible for serious disease outbreaks in poultry and humans in several Asian countries since 2003, is spread through a number of sources, including poor biosecurity at poultry farms, movement of poultry and poultry products and live market trade, illegal and legal trade in wild birds. Although unproven, it is also suspected that the virus could possibly be carried over long distances along the migratory bird flyways to regions previously unaffected (Table 1) is a cause of serious concern for the region. Avian influenza subtype H5N1 could be transported along these routes to densely populated areas in the South Asian Subcontinent and to the Middle East, Africa and Europe. -
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. -

The Making of Concessions: Traditional Authorities, Transnational
The Making of Concessions: Traditional Authorities, Transnational Capital, and Territorialized Identities in Africa By Rebecca Hardin Paper presented to the Environmental Politics Seminar UC Berkeley, April 27 2007 Draft: please do not cite, nor reproduce Note: This paper presents a framework I am developing for a book project tentatively entitled “Concessionary Cultures.” I am currently revising the project for the University of California Press series “Colonialisms.” The opportunity to benefit from the EP seminar discussion is very welcome. In developing this to date I have incurred intellectual debts to the following readers: Arun Agrawal, Susan E. Cook, Jane Guyer, Alain Karsenty, Damani Partridge, John Galaty, Nahomi Ichino, Eduardo Kohn, Nadine Naber, Devra Meuller, Abena Osseo-Assare, Lorraine Paterson, Beth Povinelli, Hugh Raffles, Jesse Ribot, Mary Steedly, Miriam Ticktin, Diana Wylie,and an anonymous reviewer for the University of California Press. The research support of McGill University, the University of Michigan, and the Harvard Academy of International and Area Studies has been crucial, 1 Nestled within the Dzanga Sangha Dense Forest Reserve and Dzanga Ndoki National Park, the small town of Bayanga is the largest settlement in that southernmost triangle of the Central African Republic (CAR) that borders Cameroon and the Republic of Congo (Brazzaville). The establishment (1988) and subsequent legislation (1991) of the Park and Reserve (which I’ll refer to at the RDS) created one of the last protected areas established in the CAR, and one of only two sizeable forest reserves in that country. Conducting research on the role of tourism and trophy hunting in the management of this protected area found me sitting one evening with a pair of professional trophy hunters over the cocktails they call “sundowners.” During their hunts with clients that week, they complained, they had found abundant evidence of poaching, and they feared that too many of the animal trophies they sought might be marred by scars from wire snares. -

Box 2012, Democratic Republic of Congo (DRC); [email protected] * Correspondence: [email protected] Received: 22 December 2019; Accepted: 20 March 2020; Published: 7 April 2020 Abstract: Humid conditions and equatorial forest in the Congo Basin have allowed for the maintenance of significant biodiversity and carbon stock. The ecological services and products of this forest are of high importance, particularly for smallholders living in forest landscapes and watersheds. Unfortunately, in addition to deforestation and forest degradation, climate change/variability are impacting this region, including both forests and populations. We developed three case studies based on field observations in Cameroon, the Central African Republic, and the Democratic Republic of Congo, as well as information from the literature. Our key findings are: (1) the forest-related water cycle of the Congo Basin is not stable, and is gradually changing; (2) climate change is impacting the water cycle of the basin; and, (3) the slow modification of the water cycle is affecting livelihoods in the Congo Basin. -

Over the drylands of the Sahara Desert and the semi-arid Sahel region, remote sensing (optical satellite imagery and digital elevation models) proved a successful approach to identify the paleo-shorelines of this giant paleo-lake. Here we present the first attempt to estimate the isostatic response of the lithosphere due to Megalake Chad and its impact on the elevation of these paleo-shorelines. For this purpose, we use the open source TABOO software (University of Urbino, Italy) and test four different Earth models, considering different parameters for the lithosphere and the upper mantle, and the spatial distribution of the water mass. We make the simplification of an instantaneous drying-up of Megalake Chad, and compute the readjustment related to this instant unload. -

In recent decades, the open water surface of Lake Chad has reduced from approximately 25 000 km2 in 1963, to less than 2 000 km2 in the 1990s heavily impacting the Basin’s economic activities and food security. -
Deforestation Trends in the Congo Basin
EXECUTIVE SUMMARY Deforestation Trends in the Congo Basin Reconciling Economic Growth and Forest Protection II Deforestation Trends in the Congo Basin ACKNOWLEDGMENTS Deforestation Trends in the Congo Basin: Reconciling economic growth and forest protection is the output of a two-year exercise implemented at the request of the COMIFAC (regional commission in charge of forestry in Central Africa) to strengthen the understanding of deforestation dynamics in the Congo Basin. The report was written by Carole Megevand with contributions from Aline Mosnier, Joël Hourticq, Klas Sanders, Nina Doetinchem and Charlotte Streck. The modeling exercise was conducted by a team from the International Institute for Applied Systems Analysis (IIASA), led by Michael Obersteiner and composed of Aline Mosnier, Petr Havlík and Kentaro Aoki. The data collection campaign in the six Congo Basin countries was coordinated by ONF-International under the supervision of Anne Martinet and Nicolas Grondard. The executive summary was edited by Flore de Préneuf. Maps and illustrative graphs were prepared by Hrishikesh Prakash Patel and Jeff Lecksell. The team is grateful for useful guidance provided by numerous experts and colleagues including Raymond Mbitikon, Martin Tadoum Joseph Armaté Amougou, Igor Tola Kogadou, Vincent Kasulu Seya Makonga, Deogracias Ikaka Nzami, Rodrigue Abourou Otogo, Georges Boudzanga, Kenneth Andrasko, Christian Berger and Gotthard Walser. Special thanks go to Idah Pswarayi-Riddihough, Jamal Saghir, Ivan Rossignol, Giuseppe Topa, Mary Barton-Dock and Gregor Binkert who, at different stages, helped make this initiative yield its full results. The study was coordinated by the World Bank and benefited from financial support from various donors, including the Program on Forests, the Norwegian Trust Fund for Private Sector and Infrastructure, the United Kingdom Government, the Trust Fund for Environmentally and Socially Sustainable Development and the Forest Carbon Partnership Facility.
