Study of the economic and social impact of forced evictions in Douala

The project to support the improvement of public policies of Cameroon in respect of the right to decent housing-Phase 2, implemented by CODAS Caritas Douala, aims to :

  • contribute to strengthening legal security, respect for the rights of victims and / or threatened expropriations;
  • mobilize the maximum of actors around the theme of forced evictions.

Specifically, it involves bringing administrative authorities, men and women in the media and CSO leaders to perceive with much greater sensitivity the problems and legitimate interests of victims and / or potential victims of forced evictions. .

The mission, to ACAGER assigned, was to raise the economic and social impact of the evictions (evictions or expropriations) perpetrated during the last 30 years on the families directly affected by the interventions of urbanization, the realization of the infrastructures, the structuring projects and the development, in the city of Douala.
Specifically, it was :

  • to establish the current situation of families directly affected by evictions from the social, economic and legal point of view;
  • to make an analysis of the capacity of the evictions perpetrated to improve the living conditions of the families directly affected by the evictions;
  • to make an analysis of the impact of these evictions on the local economy;
  • propose actions to support these families affected by the evictions.

The Atlas of Climate Change Effects Resilience and Adaptation in Ngaoundéré

Ngaoundéré faces the risks of flooding and erosion which increase in proportion to its anarchic urbanization (Tchotsoua & Bonvallot, 1999). The flood-prone areas susceptible to landslides of rock boulders and water erosion are partly squatted by the populations who build houses made of temporary materials. Abundant rainfall (between 1,300 and 1,500 mm), concentrated during the rainy season, accelerates flooding and erosion on the hillsides.

Given its location near the Sahel, the town of Ngaoundéré is thus very exposed to the climate change which affect human and natural systems in many ways, disrupting food and water supply, destroying infrastructure, flooding homes, changing infectious disease vectors, eroding livelihoods, and decreasing economic opportunities, especially in agriculture (The World Bank Group, 2019).

The success of efforts to overcome these effects of climate change is often linked to collaboration among stakeholders in exploiting risk information to take meaningful action. It is in this context that the Open City project in Africa is taking place, of which Ngaoundéré is one of the pilot towns.

One of the flagship products of the project is the production of the cartographic Atlas for the resilience and the adaptation to these natural phenomenon more and more exacerbated by the man.

Resilience and adaptation are two interrelated responses to the various impacts of climate change on people, communities, ecosystems, infrastructure, as well as the economy, industry and businesses. Resilience is the amount or size of impacts that a sector can withstand before undergoing a complete transformation. Climate change adaptation refers to any activity that reduces the negative effects of climate change or that takes advantage of new opportunities arising from climate change.

The atlas, in soft and hard copies, in French and English, presents the geographical, human and socio-economic frameworks before characterizing and analyzing the flood and geomorphological risks in the neighborhoods. Each analysis is accompanied by recommendations previously discussed with the populations of each neighborhood.

The city of Ngaoundere faces recurring challenges related to the risks of natural disasters, which increase as its rapid and unplanned urban growth continues. Between 2005 and 2015, the city's population increased from 180,763 to nearly 270,000, and its urban footprint nearly doubled from 3,648 ha to just over 6,381 ha.

Its urbanization has taken place, largely spontaneously, resulting in increasing occupation of many flood-prone wetlands each year, from May to September, and mountain slopes at the risk of rock boulders without prior arrangements. . Given its location in the Sudano-Sahelian environment, the city of Ngaoundéré is also exposed to the extreme effects of climate change.

While a Master Plan d'Urbanisme (PDU) and land-use plans were approved in 2016 to guide its future urbanization, the Ngaoundéré City Council lacks basic tools to effectively guide land use. and maintain the various existing basic infrastructures. The Urban Community of Ngaoundéré (CUN), which does not yet have an operational Geographic Information System (GIS) of the city, is limited to the use of physical maps, most of which are obsolete.

Thus, the challenge is to facilitate access to up-to-date georeferenced information, in particular on basic infrastructure (urban equipment, roads, drainage, land use, etc.), in the form of physical and digital maps, to help better decision making by analyzing this data on the one hand, and helping interactive urban planning and management on the other.

In order to meet these challenges, the Urban Community of Ngaoundéré, in partnership with the World Bank, the Global Facility for Disaster Resilience and Recovery (GFDRR), the Ministry of Housing and Urban Development (MINHDU) by the Inclusive and Resilient Cities Development Project (PDVIR), the Geomatics Laboratory of the University of Ngaoundere, civil society organizations and people living in risk areas, have pooled their efforts through the project Open Cities Africa – Ngaoundéré, to systematically collect data on the exposure and vulnerability of the inhabitants of Ngaoundéré to the risk of natural disasters. The aim is to enable the various stakeholders to better anticipate and prioritize investments to prepare the city to cope with floods, falling rocks, soil erosion and / or rockfall.

Organized in three main stages, the collaborative mapping campaign began with the collection of basic data on the city of Ngaoundere. Led by experienced community mappers OpenStreetMap Cameroon, a dozen young mappers consisting of students from the University of Ngaoundéré and trainees from the Urban Community of Ngaoundéré have published more than 20,000 objects (buildings, rivers and streets) under OSM in 2 months.

During this first phase, the team alternated between digitization, quality control and the validation of data mapped under OSM. In addition, some data collected as part of its previous activities by the  Association for Cartography and Resource Management (ACAGER) and those collected in the field by the mappers using the application QField, just over 3,000 point objects, were all loaded on OSM. In addition, using the Java OpenStreetMap tool (JOSM), the main types of land use in the city of Ngaoundéré were mapped offline and uploaded to OSM.

The second step of the collaborative mapping campaign of the urban space of Ngaoundéré consisted in the characterization of the buildings located in the zones at risk of floods and morphological. This work was done using QField integrated survey forms. Ten tablets Samsung Tab A6 were mobilized for this purpose. This collection was conducted in the field by students who were associated with some inhabitants of risk areas.

The third part of the implementation of the Open Cities Initiative in Ngaoundere consisted in the preparation and realization of the drone coverage of four districts located in the flood zone (Gadamabanga, Djalingo, Sabongari 3 and North CIFAN), and the mountains. Ngaoundéré on which are built neighborhoods Onaref, Socaret, Bamyanga and Béka Hosséré.

In the end, the Open Cities Africa Ngaoundere project will respectively permit :

  • to produce new, up-to-date, open-access data on the risks of floods, falling rocks, water erosion and bank collapse,
  • to use new tools / products (Atlas) to examine them,
  • to build the capacity of local people and,
  • to forge new partnerships between the different stakeholders.

Development of the reference situation in the PAPA/ADFL intervention zone

As part of the Growth and Employment Strategy Paper (GESP), the Government of Cameroon has initiated and obtained funding from the European Union for the implementation of the Productivity Improvement Program. agricultural sector, a support component for the development of the dairy sector (PAPA/ADFL) whose area of ​​intervention is the three northern regions of Cameroon. To allow a better follow-up of the activities of the program in order to reach its results, a mission of elaboration of the situation of reference of the project was entrusted to the Association for the Cartography and the Resource Management (ACAGER) .
