The Dutch embassy in Maputo received 2 requests from the ‘Ministério das Obras Públicas, Habitação e Recursos Hídricos’ (Ministry of Public Works, Housing and Water) for support of the DRR-Team. Both request are related to flood and erosion problems in an urban context caused by cyclones and heavy rainfall. The requested support from the DRR-Team for Nacala and for Pemba focusses on review of existing studies available on these topics in both cities. The advice of the DRR-Team should focus on priority measures that can be implemented in the Mozambican context. Advice on financing options by bilateral and multilateral partners is very relevant in this regard.
Both Nacala and Pemba experience increasing impact of climate change. In the past 26 years, 4 cyclones have hit Nacala and surrounding region. The more frequent intense rain showers also regularly cause flooding in Nacala such as in 2015 (9 deaths) and January 2018 and 2019. Pemba was hit by Cyclone Kenneth in April 2019, with 594 mm of rainwater causing severe flooding in 2 days. Both Pemba and Nacala are located on the East Coast of Africa in the area that is most affected by cyclones. These weather conditions are expected to increase in number and severity due to climate change in the coming decades.
In 2019 the municipality of Nacala performed its own analysis of the impact of climate changes (mainly cyclones). The city is located on a plateau on the coast and has increasing erosion and flooding problems due to climate change. The aim of this municipal study is to develop an integrated approach for taking mitigating and preventive measures. The DRR-Team will perform a more thorough analyses of the local physical situation and the underlying causes of the erosion and floods. The proposed solutions and measures will be reviewed and, if applicable, new measures or improvements will be advised. A roadmap for next steps to further develop projects and to arrange finance will be included in the report.
The coastal city of Pemba has similar flood- and erosion problems caused by heavy rains, but also suffers from floods from sea in the lower areas in town at the coastline. The sanitary facilities in the city are also problematic and need advice from the DRR-Team. In 2015 Gauff Engineering conducted a study, following up on a previous 2012 MCC-funded study, on storm water and wastewater problems in the city. The study contains recommendations for drainage of excess rainwater, the sewer system and the location and design of a WWTP. The request for the DRR-Team calls for advice on measures to combat erosion, improve drainage and to improve the city’s sanitation system. The goal of the DRR-Team for Pemba is to review these reports and to analyse the erosion and flood situation, determine the underlying causes and to advise on technical interventions, governance and financing options to reduce the negative impacts of erosion and floods.
As a mayor part of the activities of the DRR-Team will consist of a review of existing reports, the activities of the DRR-Team can start with the study of these reports and other relevant information from the Netherlands. If the situation in Mozambique regarding the COVID-19 impact and measures allows, the DRR-Team can organise a mission to Mozambique to assess the situation in the field and to interview relevant stakeholders.
The planning for this assignment is roughly from September till October 2020. Starting with desktop study end of September in the Netherlands and, if COVID-19 situation allows, with a mission in the second half of October to Mozambique. Total expected deployment is approximately 10 to 15 days.
A Team leader for this assignment has already been selected. The TL has been deployed in several DRR-Team missions on erosion, floods and sanitation and masters the Portuguese language.
To complete the DRR-Team for Mozambique the following profiles for expertise is required:
- Storm water erosion expert, knowledgeable in soil physics, geology and modelling and with a construction background. The expert should be able to asses and design appropriate low cost erosion control measures in combination with a storm water drainage network in hilly terrains in a urban context.
- Water and sanitation expert with specific knowledge of urban sanitation. In particular knowledge and experience in evaluating and designing sewage networks, including pumping stations, sewage treatment and wastewater treatment plants is required.
- Data and GIS expert. Information and mapping material are expected to be limited and comes in all shapes. The expert should be able to combine and geo-reference data of all kind of sources and should have ample experience in finding and using open source data on a detailed levels as possible. This includes, but is not limited to topographic maps, DTM’s, soil and land use maps, aerial views, radar, satellite and climate data. The DRR-Team results should be accessible for Mozambique in an open source GIS environment.
Experience/knowledge of the flood management and sanitation situation in Mozambique is a plus. Knowledge of Portuguese is highly desirable as some documentation is only available in Portuguese.
