Le rÈchauffement climatique et ses consÈquences amËnent ‡ mettre en lumiËre la perception du changement par les travailleurs des organisations paysannes dans le sahel. L'objectif de la présente étude est d‟examiner les caractéristiques et les perceptions des travailleurs au sein des organisations paysannes en zones humide et semi-aride, et leurs st...

The increase in temperature, floods and globalized declines in agriculturalproductivity observed in the Sahel zone of Cameroon shed light on the perception ofclimate change by women workers within peasant organizations. The objective of thisstudy is to analyze the perceptions of women workers within peasant women'sorganizations and the direct impac...

Les hausses de température, les inondations et les baisses globalisées de la productivité agricole observées en zone sahélienne camerounaise permettent de mettre en lumière la perception des changements climatiques par les femmes travailleuses aux seins des organisations paysannes. L'objectif de cette étude est d’analyser les perceptions des fem...

The increase in the magnitude of the effects of the invasion of environments by prolific invasive plants which impact biodiversity, eliminate certain major economic activities while increasing social challenges, women are increasingly vulnerable to climate change, The study of the impact of the proliferation of invasive plants on biodiversity and t...

The Biochar-Compost mixture based on the dead biomass of Prosopis juliflora and Eichhornia crassipes can be used as an input in agricultural production. The objective of this study is to determine the capacity of the Biochar-Compost mixture based on the dead biomass of Prosopis juliflora and Eichhornia crassipes on the restoration and productivity...

In Sahelian cities, desertification with its climatic corollary is due to the excessive use of firewood by increasingly growing populations. However, the dead biomasses of Azadirachta indica swept away from households and unnecessarily buried in urban waste dumps could be recycled into ecological charcoal. But, it is necessary to know the binder be...

L’acceptation des messages liés à la préservation et conservation de l’environnement par la population dépend en partie des méthodes de formation utilisées en zone sahélienne. L’objectif de cet article est de mesurer le degré d’atteinte du but de la formation via les méthodes pédagogique et andragogique au travers de la perception que les parti...

The management of invasive plants such as Eichhornia crassipes and the fruits of Azadirachta indica on the banks of the waters of Lake Chad in the Far North of Cameroon remains a challenge to overcome. On the other hand, given the urgency of finding other sources of energy following the scarcity of fossil fuels, it becomes appropriate to turn to re...

The objective of this study is to evaluate the economic quality of charcoal based on Prosopis juliflora linked to Eichhornia crassipes and to determine its index economic value. The density of the charcoal based on Prosopis juliflora (50≤%) and Eichhornia crassipes (50≥%) is 0.395±0.037g/cm 3 with the average humidity rate before drying of 48.89±14...

Eichhornia crassipes is an invasive plant in the waters of Lake Chad. The ecological problems caused by its permanent and invasive presence lead to search solutions. Thus its valuation as cooking energy is an option whose objective is to assert the effect of production processes of ecological coal based on Eichhornia crassipes on their performance...

The acceptance of messages related to the preservation and conservation of the environment within populations depends in part on the training methods used in the Sahel zone. The objective in this article is to measure the achievement of the training goals via educational and andragogical methods by analyzing the perception that the participants hav...

Thus its valuation as cooking energy is an option whose objective is to assert the effect of production processes of ecological coal based on Eichhornia crassipes on their performance...

The objective of this study is to evaluate the ecological quality of charcoal based on Prosopis juliflora linked to Eichhornia crassipes and to determine its index ecological value. The collection and preparation of 1.05±0.32 Ton of mixed dry biomass of Prosopis juliflora and Eichhornia crassipes, made it possible to obtain on average 0.918±0.234 T...

Combustibles briquettes are energetics resources, which could be use to substitute other types of energy. Optimization of energetic efficiency of combustible briquette lead us to made it so that to contribute to thrift wood resources and local sustainable development. Valorization of dry dead leaves of Azadirachta indica associated to dry stems of...

Le problème de gestion de déchets papier-cartons présente une pollution locale, due à la présence des alliages métalliques ayant servi de reliure et potentiellement dangereux pour l’environnement et la santé humaine, et une pollution diffuse, due à la présence des encres également potentiellement dangereux pour l’environnement et la santé humaine....

The problem of paper and cardboard waste management presents local pollution, due to the presence of metal alloys used as binding and potentially dangerous for the environment and human health, and diffuse pollution, due to the presence of inks also potentially dangerous for the environment and human health. Not mastered, this management could be a...

Les briquettes combustibles sont des ressources énergétiques pouvant être utilisées en substitution aux autres types de sources d’énergies. L’optimisation du rendement énergétique des dites briquettes combustibles nous amena à fabriquer ces derniers afin de contribuer à l’économie des ressources et au développement durable local. La valorisation de...

In this work, the objective is to propose conceptual models of improved stoves capable of saving fuels and increasing the energy autonomy of cooking stoves. The stove construction technique has made it possible to manufacture ecological and sustainable improved cooking stoves. The Active Method of Research and Participatory Planning (MARPP) was use...

Les problèmes de la gestion des déchets, avec leur cortège de fléaux collatéraux, constituent des menaces graves pour la survie de l’humanité sur notre planète. Le système de gestion des déchets à Maroua dans l’Extrême-Nord du Cameroun pose des problèmes du fait de l’absence du tri dans les ménages et du type d’enfouissement ne respectant pas l...
