Abstract. Considered as a management tool for town planning and urbanization in Senegal, the management of the concerted development zone program is carried out by the Department of Town Planning and Architecture. Its implementation includes the land, the actors and the beneficiaries, hence a large amount of information to manipulate. However, until 2019, this information is not yet formatted in the interactive database. The objective of this article is to show the importance of the integration of a geographic information system in the field of town planning, in particular in the management of the concerted development program. It involves linking urban planning and geomatics through the creation of an internal GIS database from data extracted from satellite images and collected in the field.
Keywords : Concerted Development Zone, urban planning, Geographical Information System Database, Geomatics.

Abstract. Since 2006, the problem of illegal parking is fought by the public authorities of the city of Yaoundé. To curb this phenomenon, they instituted paid parking and a framework for its good management. Unfortunately, these measures have not been enough to effectively mitigate the situation and the consequences were perceptible through illegal parking and conflicts between actors. To help improve parking management in the city, and to support fair decision-making, we have detected by geographic information systems and field surveys, the areas in the central town with the greatest parking challenges thanks to a multi-criteria analysis witch led to the data crossing of penalized illegal parking and the congestion rate of the streets. The results show that on 51% of these streets, the demand expressed is 02 to 10 times superior to the offer. However, the greatest difficulty is centered on three corridors namely, the ministerial area, the perimeter of the Elig-essono junction and finally the rosary of Bank Avenue, the city hall, the ministry of communication, SGBC Anne -rouge, Central Market, Kennedy and Mfoundi Market.
Keywords : Parking, GIS, congestion rate, illegal parking penalty, parking pressure.

Abstract. Cameroon, like most African countries, has entered the Decentralization area. However, municipalities lack reliable decision support tools, including GIS databases. The Cameroonian government, with the help of the multilateral and bilateral donor community, has put in place a process whose objective is to enable decentralized territorial communities to acquire effective means in the process of decentralization. The National Program for Participatory Development (PNDP) being one of the operational frameworks for the implementation of the poverty reduction strategy in its component "Support to local development", following a preliminary diagnosis with a view to the determination of the indicators of the reference values, financed the development of a Communal Development Plan (PCD) of the municipality of Tignère. Thus, the Association for Mapping and Resource Management (ACAGER) was selected to provide technical assistance to the realization of this plan, one of whose major objectives was the constitution of a database with spatial reference for the municipality of Tignère. This communication gives the definition of the GIS, the method developed for the realization of the GIS of the Municipality of Tignère as well as some results directly exploitable by the Commune before concluding by a certain number of challenges to raise for a better contribution of the databases GIS to an efficient, effective and profitable management of Decentralized Territorial Communities.

Abstract. Urban land, by its appropriation and especially its valuation, poses urban management problems to Chadian cities. Analyzed in the case of Doba, in southern Chad, from 2003 to 2018, it is indicative of an urban paradox characterized by the ruralization of its uses. This study aims to diagnose this phenomenon, in order to formulate suggestions for its consideration in the urban planning tools of this average city in Sub-Saharan Africa. To try to answer the question of the ruralization of urban land uses in Doba, the hypothetico-deductive approach is used with a methodology that combines qualitative and quantitative approaches. The tools used are direct observations, informal interviews, desk research, GPS surveys and field survey. The mapping tools are made using 2003 input data, coupled with those collected in 2018. The results obtained show that Doba has been known since 2003 as the main oil city of Chad. However, an increase in the area of food crops from 31770.5 to 50675 hectares is recorded around the city by the deconcentrated services of the National Agency for Rural Development. Moreover, the urban area of this agglomeration is increasingly marked by home gardens and small vegetable farms, which are added to the Casier C, a hydro-agricultural perimeter on the periphery of the city. These different farming practices confirm a progressive tendency to the ruralization of urban land uses in Doba.

Abstract. This article presents the results of the evaluation of the impact of the standard of living of the populations on the strategies of fight against Malaria in Daloa. On the basis of desk research, interviews and a household questionnaire survey, we categorized households according to the reasoned sampling method. This is the selection of sampling units (neighborhoods and urban households). The neighborhoods are carefully selected and classified into 3 categories (residential, evolving and precarious neighborhoods), while households are randomly selected (175) and surveyed according to the step method and ranked according to sociodemographic indicators of the level of life with their preferred means of fight against malaria. It appears that different living standards through indicators such as neighborhood types (precarious, evolving and residential) (incomes, types of employment, school level, household size) have a significant impact on strategies for fighting malaria.
Keywords : Daloa, malaria, standard of living, control strategies.

Abstract. The participatory approach to protected area management started since the Rio de Janeiro Conference of 1992 became applicable in Cameroon with the law n° 94/01 / of January 20, 1994 governing the forest regime. The said law recognizes the right of village communities to profit from their forest (Article 8). Thus, the populations bordering Bouba Ndjidda National Park benefit from the wealth of this park. The objective of this article is to analyze the contribution of local jobs and wildlife fees to the improvement of the living conditions of local residents. The adopted methodology is based on cartographic data from GPS surveys and PSFE data (Forest Environment Sector Program), surveys based on a sample of 283 individuals representative of local populations. Then the interviews with the park managers supplemented the field observations. The results show that local populations benefit from local jobs recruiting 219 people and wildlife fees contributing to local development: 15% in the health sector, 20% in education and 15% in water supply, in the six villages surveyed, 12 holes were drilled thanks to the fallout from wildlife fees.
Keywords : Local development, village lands, National Park, North Cameroon.

Abstract. For more than twenty years, charcoal has been the economically accessible source of energy for people in the Sudano-Sahelian zone. In the western periphery of the Bénoué National Park, the commercialisation of charcoal is a flourishing activity, providing income to households. The aim is to evaluate the socio-economic impact of charcoal commercialisation in the western peripheral terroirs of the Bénoué National Park. The data collection was done in two terroirs (Banda and Samoh gouna), thanks to the techniques of direct observation, field surveys (150 actors) and interviews. These data were processed and analyzed in Excel. The results obtained show that the marketing of charcoal involves significant social and economic issues because about 80% of the population benefit from the income from this activity to meet their basic needs.

Abstract. L’eau source de vie peut être une menace de par son absence ou son excès, d’où la nécessité d’aménagement pour en tirer le meilleur. Sur la base de l’analyse des précipitations, de la topographique, des résultats des enquêtes et des observations directes de terrain, les auteurs de cet article appréhendent la contribution du lac artificiel de Man sur les inondations  et par conséquent sur les populations. A Man, si les facteurs naturels exposent aux risques d’inondations, les facteurs anthropiques se présentent comme les causes aggravant la vulnérabilité des habitants, par le non entretien des infrastructures de gestion des eaux pluviales, notamment, le lac artificiel.
Keywords : Man, Thérèse neighborhood, flood, market, artificial lake.
