FEASIBILITY STUDY of a HYDROPOWER FACILITY in EASTERN ANGOLA Civil Engineering FEASIBILITY STUDY OF A HYDROPOWER FACILITY IN EASTERN ANGOLA João Pedro Marques Santos Coelho Thesis to obtain the Master of Science Degree in Civil Engineering Hydraulics and Water Resources Supervisor: Prof. António Bento Franco Examination Committee Chairperson: Prof. António Alexandre Trigo Teixeira Supervisor: Prof. António Bento Franco Members of the Committee: Prof. António Alberto do Nascimento Pinheiro December 2015 ABSTRACT The increasing demand in the energy sector and global energy needs, determined by the growth of the world’s population and socio economic development, is considered by many experts as an opportunity for the definition and implementation of a sustainable energy model, which enables energy access to all potential users in a perspective of rational and efficient use of the available energy resources. Among the renewable energy technologies used worldwide, hydropower plays a major role being the most used renewable energy source at the moment. In Angola there is a great abundance of this natural resource and a great potential in the hydropower sector, which is not yet developed. In the country there is also a great deficit in what concerns the available energy per capita. In this master thesis, it is presented a feasibility study of a hydropower facility in the Eastern Angola, one of the most deprived areas in terms of access to energy, within the Angolan territory. The hydropower facility is supposed to supply the city of Saurimo, the capital of the Lunda Sul province, that has an estimated population of about 200 000 inhabitants. The present study includes an analysis of the Chiumbe River, in all its extents inside the Angolan boarders, in order to determine the best possible location to build a hydropower facility. After the selection of the best location, an optimization of some of the parameters of the facility is made, as well as a pre-study and primarily analysis on floods, hydraulic structures, equipment’s and construction materials. Also a preliminary estimative of the quantities and works associated with the construction of the facility is elaborated, as well as an economic analysis, for the best location in the Chiumbe River to construct a hydropower facility, and also for the more adequate configuration. This economic analysis gives the first idea whereas the facility will be profitable. Keywords: Angola, Saurimo, Chiumbe River, hydropower facility, feasibility study. i ii RESUMO As perspectivas futuras para o crescimento da população mundial e o crescimento socioeconómico esperado, determinam, entre outros aspectos, um aumento das necessidades energéticas a nível global. Este aumento das necessidades no sector energético é considerado por muitos especialistas como uma oportunidade para definição e implementação de um modelo energético sustentável. Este modelo permitirá o acesso a energia por todos os potenciais utilizadores usando, de forma racional e o mais eficiente possível, os recursos energéticos disponíveis. De entre as fontes energéticas utilizadas actualmente, a hidroelectricidade tem um papel muito significativo, sendo a fonte renovável mais utilizada a nível mundial. Em Angola existe uma grande abundância deste recurso natural, e consequentemente um grande potencial no sector da hidroelectricidade que ainda não se encontra aproveitado. Além disso, verifica-se um grande deficit em termos de energia disponível por habitante. Na presente tese de mestrado, é realizado um estudo de viabilidade de um aproveitamento hidroeléctrico no Nordeste de Angola, uma das zonas menos desenvolvidas do país ao nível do acesso à energia. O aproveitamento hidroeléctrico em questão, tem como objectivo abastecer a cidade de Saurimo, capital da província de Lunda Sul, com uma população estimada de 200 000 habitantes. O projecto passa por uma análise do rio Chiumbe em toda a sua extensão, dentro do limite das fronteiras Angolanas, com o objectivo de determinar a melhor localização para a construção de um aproveitamento hidroeléctrico. Uma vez definida a localização mais adequada, foram também analisados alguns dos parâmetros do aproveitamento, nomeadamente um pré- estudo relativo às cheias, principais estruturas hidráulicas, equipamentos e materiais de construção. É também definido um mapa de quantidades e desenvolvida uma análise económica, para aquela que foi considerada a melhor localização para o aproveitamento, e para a configuração mais adequada. Esta análise económica permite ter uma primeira ideia se o aproveitamento será rentável. Palavras-chave: Angola, Saurimo, rio Chiumbe, aproveitamento hidroeléctrico, estudo de viabilidade. iii iv AGRADECIMENTOS Esta tese surgiu no âmbito do meu programa Erasmus, realizado em Lausanne mais concretamente na École Polytechnique Fédéral de Lausanne (EPFL). O presente tema era uma das propostas da Universidade e foi um dos motivos que despertou interesse em embarcar neste programa. Desde que voltei de Erasmus continuei a desenvolver este projecto, já no IST e com o apoio do Professor António Bento Franco. O tema em questão consistia num projecto bastante ambicioso que não teria sido possível desenvolver sem a ajuda e o apoio de várias pessoas a quem gostaria de agradecer nos parágrafos que se seguem. Em primeiro lugar gostaria de agradecer a toda a minha família por estarem sempre no meu canto e a torcer pelo meu sucesso académico, nomeadamente aos meus pais, ao meu irmão e aos meus avós.

  • Evidence from the Kuba Kingdom*
    The Evolution of Culture and Institutions:Evidence from the Kuba Kingdom* Sara Lowes† Nathan Nunn‡ James A. Robinson§ Jonathan Weigel¶ 16 November 2015 Abstract: We use variation in historical state centralization to examine the impact of institutions on cultural norms. The Kuba Kingdom, established in Central Africa in the early 17th century by King Shyaam, had more developed state institutions than the other independent villages and chieftaincies in the region. It had an unwritten constitution, separation of political powers, a judicial system with courts and juries, a police force and military, taxation, and significant public goods provision. Comparing individuals from the Kuba Kingdom to those from just outside the Kingdom, we find that centralized formal institutions are associated with weaker norms of rule-following and a greater propensity to cheat for material gain.

    Angolan Giraffe (Giraffa camelopardalis ssp. angolensis) Appendix 1: Historical and recent geographic range and population of Angolan Giraffe G. c. angolensis Geographic Range ANGOLA Historical range in Angola Giraffe formerly occurred in the mopane and acacia savannas of southern Angola (East 1999). According to Crawford-Cabral and Verissimo (2005), the historic distribution of the species presented a discontinuous range with two, reputedly separated, populations. The western-most population extended from the upper course of the Curoca River through Otchinjau to the banks of the Kunene (synonymous Cunene) River, and through Cuamato and the Mupa area further north (Crawford-Cabral and Verissimo 2005, Dagg 1962). The intention of protecting this western population of G. c. angolensis, led to the proclamation of Mupa National Park (Crawford-Cabral and Verissimo 2005, P. Vaz Pinto pers. comm.). The eastern population occurred between the Cuito and Cuando Rivers, with larger numbers of records from the southeast corner of the former Mucusso Game Reserve (Crawford-Cabral and Verissimo 2005, Dagg 1962). By the late 1990s Giraffe were assumed to be extinct in Angola (East 1999). According to Kuedikuenda and Xavier (2009), a small population of Angolan Giraffe may still occur in Mupa National Park; however, no census data exist to substantiate this claim. As the Park was ravaged by poachers and refugees, it was generally accepted that Giraffe were locally extinct until recent re-introductions into southern Angola from Namibia (Kissama Foundation 2015, East 1999, P. Vaz Pinto pers. comm.). BOTSWANA Current range in Botswana Recent genetic analyses have revealed that the population of Giraffe in the Central Kalahari and Khutse Game Reserves in central Botswana is from the subspecies G.

Devido à recusa da descolonização pela ditadura salazarista, a independência dos PALOP realizou-se quinze anos mais tarde do que na maioria das outras colónias europeias em África, na sequência da Revolução de 25 de Abril de 1974 em Portugal. Consequentemente, o contexto histórico-político da descolonização das colónias portuguesas caracteriza-se por algumas particularidades, nomeadamente lutas armadas de libertação, períodos de transição curtos, o êxodo dos colonos portugueses (Angola, Moçambique) e, depois da independência, a instalação de regimes monopartidários de orientação soviética que marcaram os primeiros quinze anos dos PALOP. Passados 35 anos desde a independência política, os caminhos percorridos pelos Cinco mostram semelhanças e diferenças, mudanças e continuidades e, apesar dos desenvolvimentos em algumas áreas, muitas esperanças que a independência criou ficaram ainda por realizar.

(*) Corresponding author: [email protected] Abstract A preliminary assessment of Ephemeroptera species diversity in Angolan freshwater ecosystems is presented. The results are based on three surveys carried out between 2016 and 2018, supplemented by literature synthesis. The area studied includes headwater streams and tributaries feeding the Okavango Delta, namely the Cubango, Cuito and Cuanavale Rivers, which together produced 35 species, and those flowing into the Zambezi River system, the Cuembo, Cuando, Luanginga and Lungué-Bungo Rivers which together produced 29 species. Twenty-one species were identified from the Cubango River, a fast flowing, rocky substrate river, different in character to all the other rivers surveyed. The other rivers, which all flow over Kalahari sand substrate with dense rooted aquatic macrophytes, generally lacking rocky substrate, produced 33 species between them. Prior to this research, only one mayfly species had been described from Angola in 1959.
