Since the early 1990s, the concepts of land use planning and management of natural and human resources are at the centre of environmental concerns.
We cannot see, at fair value by the way, the speed of development in a country and stand out in relation to the future and the sustainability of its territories, then when we identify with the policies, the citizenship and governance based on transparency in the management of environmental objects. It is defined as “being both the natural environment and the concrete environment, constructed by man and all that affects the behaviour of man” (George, 1993).
For us, therefore, we are convinced of the reciprocal and complementary relations between the planning, the management of the resources and the planning of the territory and it is even said, that any territory which wants to be attractive, accessible and competitive, must be first arranged developed and planned. It must also reconcile globalized politico-economic actors and societal recomposition in the process of citizenship and emergence.
In practice, spatial planning and resource management are operational, orderly and concerted actions of the different actors, across the different territories of a country, to mitigate territorial imbalances, propose the substitution of a new order better than the existing, according to a prospective vision, advocating the humanization of growth.
The objective, endogenous development, promoting a better territorial distribution of the population, activities and equipment … for the proper functioning of the internal socio-economic system, in order to harmonize the growth, well-being and development of population. This must go through the political compromise, the social peace and the legitimacy of the actor-producer of territorial development on the basis of spatially referenced data.
This is what we call exogenous development, by a good integration and a good anchoring to the local, regional, continental and global system, favoring the development of exchanges of all kinds.
This new vision of spatial planning and resource management can only succeed in a democratic, decentralized, participatory, anticipatory, transparent and good governance environment in accordance with the expectations, wishes, requirements and / or needs of the stakeholders.
It is through good spatial planning policies and good resource management mechanisms that tropical countries can correct imbalances and guide spatial developments from a holistic perspective and a comprehensive and forward-looking project.
Thus Labe Sadjo Solange et al. Have studied the impact of the influx of refugees in the localities of Borgop and Ngam in Adamaoua that shelter Central African refugees. A similar assessment is made by Robert Madjigoto et al. in the Department of Nya-Pendé in Chad. The impact of the refugees and that of urban growth is mainly felt on the vegetal cover (Bouyo Ndoledje et al.) which is however an important source of ecosystem services especially with regard to the above-ground biomass including Junior Baudoin Wouokoue Taffo et al. have proposed in their paper, allometric equations mon and multi-specific for its estimate in the savannahs of the Highlands of West-Cameroon.
Still under the wake of the development, Aline-Joëlle Lembe wife Bekale takes a critical look at the policies to boost management dynamics and sustainable organization of marine fisheries in Gabon. Martin Blao Zoua et al., Analyzes the spatial evolution and rôneraies in Loug-Chari continues to be exploited in a fraudulent way by the populations in spite of the decree prohibiting the cutting of the green wood in Chad. He noted that given the challenges, the challenges and the interests that emerge from the current form of timber exploitation in Loug-Chari, it is urgent to set up a consensual management structure. Its results make it possible to understand the strategies of actors and give leads for the planning and the management of this resource. Germain Bock et al. implement mobile GIS and vertex tool in the forest management laboratory of the National School of Water and Forests of Mbalmayo.
West Africa has been well illustrated by studies in urban areas. Thus, Souleymane Diabagate analyzes socio-spatial inequalities related to urbanization in the city of Bouaké in Ivory Coast. Beh Yeo et al. analyze the explanatory factors of the drinking water deficit in households in Bouaké.
Félix Saintervil et al. shows the contribution of Geomatics in the mobilization and collection of taxes in the Municipality of Saint Louis North in Haiti. And Jean de Dieu Nzila et al., Evaluates the impact of the maala écobuage on the physicochemical properties and the productivity of acidic clay soils of the Niari Valley (Congo).
That is what the volume 3 of IJGPRM delivers.
