Dr. Pinny was assigned the task of reviewing the published literature on water management issues in the Zambezi river basin, and related ecological ques- tions. At the outset, I thought that a literature review on the Zambezi river basin would be a rather slim report. I am therefore greatly impressed with this Working Paper, which includes a large number of references but more importantly, syn- thesizes the various studies and provides the scientific basis for investigating a very complex set of management issues. Dr. Pinay's review will be a basic refer- ence for further water management studies in the Zambezi river basin.

  • Mozambique Case Study Example1
    Mozambique Case study example1 - Principle 1: The Zambezi River Basin - "dialogue for building a common vision" The Zambezi River Basin encompasses some 1.300 km2 throughout the Southern African Development Community (SADC) region, including a dense network of tributaries and associated wetland systems in eight countries (Angola, Namibia, Botswana, Zimbabwe, Zambia, Malawi, Tanzania, Mozambique). The livelihoods of approximately 26 million people are directly dependent on this basin, deriving benefits from its water, hydro-electric power, irrigation developments, fisheries and great wealth of related natural resources, including grazing areas, wildlife, and tourism. Over the past forty years, however, the communities and ecosystems of the lower Zambezi have been constraint by the management of large upstream dams. The toll is particularly high on Mozambique, as it the last country on the journey of the Zambezi; Mozambicans have to live with the consequences of upriver management. By eliminating natural flooding and greatly increasing dry season flows in the lower Zambezi, Kariba Dam (completed in 1959) and especially Cahora Bassa Dam (completed in 1974) cause great hardship for hundreds of thousands of Mozambican villagers whose livelihoods depend on the ebb and flow of the Zambezi River. Although these hydropower dams generate important revenues and support development however, at the expense of other resource users. Subsistence fishing, farming, and livestock grazing activities have collapsed with the loss of the annual flood. The productivity of the prawn fishery has declined by $10 - 20 million per year -- this in a country that ranks as one of the world’s poorest nations (per capita income in 2000 was USD230).

  • Electrifying Colonial Africa: Portuguese Developments
    Major technological networks and sovereignty Electrifying colonial Africa: Portuguese developments Ana Paula SILVA ABSTRACT The electrification of Portuguese African colonies was a long-term process beginning in the late nineteenth century. Interestingly, it was boosted by a late effort of Portuguese colonialism after World War II, in the international context of the ‘second colonial occupation’, following the example of other European colonial powers. But it faced both international censure and the pressure of liberation movements such as the Marxist “Frelimo” breaking through in Angola, Guinea, and Mozambique in the early 1960s. Le barrage de Cabora-Bassa, au Mozambique. Source : Climate and development knowledge network. Portugal built electricity generation facilities in Africa from the late 1890s until 1976, two years after its retreat from the continent. Indeed, the military insurgency (1974) that removed the dictatorship and paved the way for democracy and decolonization did not prevent the completion of works under construction. The electrification of Portuguese colonies (Cape Verde, Guinea-Bissau, Sao Tome and Principe, Angola, and Mozambique) began with isolated, small-scale generators supplying farms/plantations, industries, and municipalities with lighting, promoted by colonial administrators and private entities. After World War II (WW II), the process changed completely. In the aftermath of WW II, Europe recovered on the basis of overseas territories development, for which the Marshall Plan allocated funds. Also driven by the urgency to promote the progress of indigenous peoples and the need to plan public investment, this economic development was carried out through the adoption of systematic plans: France drew up plans for its overseas territories in 1946, Belgium for Congo in 1948, Italy for Somalia in 1954, and Britain for several territories at different dates.

  • Allen F. Isaacman and Barbara S. Isaacman, Dams, Displacement, and the Delusion of Development: Cahora Bassa and Its Legacies In
    Allen F. Isaacman and Barbara S. Isaacman, Dams, Displacement, and the Delusion of Development: Cahora Bassa and its Legacies in Mozambique, 1965-2007 (Athens (OH): Ohio University Press, Coll. ‘New African Histories’, 2013), 324 pp. Pbk $32.95, ISBN: 9780821420331. Dams represent a major investment, both economically and ideologically. They de- mand large financial resources to be built, and sustained campaigns to convince af- fected people that dams will serve their interest and they should therefore voluntarily leave areas to be flooded. Since the 1980s, postmodern and postcolonial authors have submitted ‘development’ and ‘high modernism’ to a thorough critique. Yet belief in development continues to dominate political elites, and more and ever bigger dams are consequently built all over the world. In Africa, the NGO International Rivers counted no fewer than 67 large dams being ‘proposed, under construction, rehabili- tation, or expansion’ in 2010. In Dams, Displacement, and the Delusion of Development (DDDD), Allen and Barbara Isaacman investigate the history and legacies of one of Africa’s largest dams, Cahora Bassa, which was built in Mozambique by the Portuguese in the late 1960s and early 1970s. The dam was constructed under conditions of war and it was inaugurat- ed after independence by a government led by the Liberation Front of Mozambique (Frelimo). The dam has since operated continuously, though much of its electricity has not been exported or used for many years because armed rebels had destroyed many high voltage power line pillars. Since the end of the armed conflict in 1992, power lines have been rebuilt and Cahora Bassa has provided electricity again, pri- marily to South Africa, though increasingly to the national Mozambican grid as well.

    Landmines and Spatial Development Appendix I History of Conflict ∗ Giorgio Chiovelliy Stelios Michalopoulosz Universidad de Montevideo Brown University, CEPR and NBER Elias Papaioannoux London Business School, CEPR December 4, 2019 Abstract This appendix provides an overview of two key periods in the recent history of Mozambique that are intimately linked to landmine contamination. The appendix is not intended to be a comprehensive reconstruction of the War of Independence or the subsequent Civil War. Its aim is to highlight, in a concise way, the events that led Mozambique to be a classified as \heavily mined" at the end of hostilities in 1992. We start by going over the war of independence (1964−1974) and then discuss the ensuing civil war (1977 − 1992). Going over the historical narrative is useful, as it highlights the underlying causes of the widespread usage of landmines. It also puts in context the gigantic effort to clear the country from the thousands of minefields after the peace agreement. We conclude by describing socioeconomic conditions at the end of civil war in 1992. ∗Additional material can be found at www.land-mines.com yGiorgio Chiovelli.
