DAM SYNCHRONISATION AND FLOOD RELEASES IN THE ZAMBEZI RIVER BASIN: ANNEX 4 OF FINAL REPORT Table G.1: Estimated number of people in refuge camps in 2007in Caia and Mopeia District (Mozambican Government et al. 2007) Zambezi province Sofala province Mopeia district 16,870 Caia District 51,823 Chimuara Noere 683 Tchetcha 2300 Nhacatundo 4,060 Namacherene 346 24 de Julho 2,065 Mapalane 325 Zona verde 4,294 Mpfumo Domingus 385 Bras 575 Magagade 319 Nzanza Sede 405 Sede DAF 1386 Namirere 1332 Zimbabwe 554 Valeta 809 Chandimba 1585 Mopeia Kalangana 512 Nhambalo 14390 Ambrosio 2135 Nhambalo 21892 Mfumo Conkho 488 Chipuazo 300 Chiramba 2232 Njezera 1955 Marra 1205 Murraca Sapanda Muanaleza 579 Mfumo Inacio / Bingala Lole 264 Sapanga Macruzo 345 Nhacuecha 973 Table G.1: Estimated number of people in refuge camps in 2007in Caia and Mopeia District (Mozambican Government et al. 2007)Table G. shows an estimate of the number of people that stayed in refugee camps in Caia and Mopeia district. Specifically for the area around Caia (Mozambican government et al., 2007) recommended the following improvements in terms of emergency relief: 1. Increase aid efforts: latrines, shelter, mosquito nets, soap and food. 2. More community involvement 3. Accommodation centres should have been better equipped with basic infrastructure prior to the crisis, since floods are recurrent in these areas. In the operational report on the 2007 flood (Government of Mozambique et al. 2007) it is further mentioned that “Many of the accommodation centres were set up during the 2001 floods and were later designated as permanent resettlement centres, where health and education facilities have since been established. Some tension has been reported – particularly around Caia – between people who moved to these resettlement centres after 2001 and people displaced by the current disaster. While their houses have been largely untouched by the floods, residents of the resettlement centres have still been affected and also feel that they should benefit from the emergency assistance being provided to the newly displaced.” This shows that flood risk zoning in terms of settlement has already been taking place to some extent. No additional data were available on the vulnerability levels of people in the area. But the area is generally poor to very poor. G-4
DAM SYNCHRONISATION AND FLOOD RELEASES IN THE ZAMBEZI RIVER BASIN: ANNEX 4 OF FINAL REPORT Flood risk mapping As for the Chobe River case study, a series of maps have been prepared showing how a system for flood risk classification could be applied to this site. An outline of these maps is provided below (note that details explained in the Chobe River case study that also apply to this study have not been repeated): Map 1 Caia – Flood Inundation Mapping for the Lower Zambezi River near Caia Case Study: this map shows the 2008 flood inundation extent based on data obtained from UNOSAT. This was the largest flood for which inundation data was available, the 2001 flood being slightly smaller. Map 2 Caia - Conceptual Flood Risk Mapping for Community Education, Zambezi River near Caia Case Study: as for the Chobe River case study, this map shows how the available flood inundation data could be used to identify areas where the awareness of the community should be raised through education and training on how to respond to flood situations. Map 3 Caia – Conceptual Flood Risk Mapping for Regulation of New Development, Zambezi River near Case Study: as for the Chobe River case study, the main purpose of this map is to demonstrate how historical flood inundation data could be used to regulate new development. Map 4 Caia – Conceptual Flood Risk Mapping for Warning and Rescue, Caia Case Study: the last map in the series demonstrates how flood risk mapping could be used to develop mobilization and response plans for evacuation of people in potentially flooded areas to higher ground refuge areas in a flood situation.
