The objective of this study is to characterize the solid household waste of the city of Thiès and to propose ways of valorization. In order to carry out this study, a physical characterization campaign was carried out using the household waste characterization method (MODECOM) modified and adapted to the national context. The results of this campaign revealed that the fines represent more than 50% of the flow emitted by the medium and low standing. For the high standings, this fraction represents only 40%. Putrescibles (between 5% and 20% depending on the standing), plastics, cardboard, composites and paper are the most produced by the population. Similarly, the granulometry is dominated by the fraction of fines followed by the average diameters. The daily ratio is 0.528 kg/capita/day.The main characteristics determined during the physicochemical characterization are the carbon-nitrogen ratio (27), the chemical oxygen demand (263.8 mg/g), the biodegradability (3) and the methanogenic potential (312.69). The methanization of this waste produced a biogas with a maximum methane content of 41%. This methanization was controlled by monitoring two main parameters which are temperature and pH.

The Bwamanda Integral Development Center (CDI-Bwamanda), Asbl-Ongd has experienced recessions which have had direct or indirect repercussions on the development of the rural population of this region (North Ecuador).This study will highlight the actions of CDI-Bwamanda since its creation until 2010 and the current reality experienced by the population which shows the decline in living standards and poverty since 2011, when the recession began.The results of this study allow the politico-administrative authorities, both national and provincial, Full Members and Administrators of CDI-Bwamanda to tackle this problem head-on and to provide substantial support to the unique development institution of this region.

This article aims to demonstrate in order to propose possible solutions, the governance of public affairs by political parties. In other words, it examines the role played by political parties and/or political groupings in the management of public affairs at a time of consensual management of the country, while emphasizing the posture of Congolese politicians who are more at listening to the watchwords of the parties and consequently relegating to the background the institutional collaboration as provided for by the constitution. Indeed, good governance is at the heart of the development policies advocated by international institutions. However, in fragile states like the DRC, its implementation comes up against strong resistance. The rule of law that the DRC wants to be is one in which the Constitution imposes on everyone, that is to say, on the State itself, on its agents and on the rulers, respect for the rules of law. Unfortunately, the management of resources in the DRC is far from approaching the principles of good governance to which the Democratic Republic of Congo claims through its constitution of February 18, 2006. It is observed that the actors involved in the management of public affairs act not, on behalf of the higher interest of the Nation but on the contrary, by conforming to the dictate of their political parties or political regrouping, which led us to qualify suddenly, the DRC of a State-parties.

Background: The National Healthy Schools and Villages Program aims to provide and maintain water, hygiene and sanitation facilities in rural and peri-urban villages and schools in the Democratic Republic of Congo (DRC). In South Kivu, at least 75% of projects fail when the involvement of the population is not taken into account. This is the case of the Bunyakiri Health Zone where a weak appropriation of the achievements of the Healthy Schools and Villages Program in the post-certification phase is observed, resulting in the loosening of the community. The aim of the study was to determine the factors associated with low ownership of the post-certification phase of Healthy Schools and Villages Program. Methodology: The study was descriptive cross-section using a semi-structured questionnaire. It involved 383 households located in healthy villages and 69 certified schools. Data processing and analysis was done using Stata v14 software. We used the Chi-square test to compare categorical variables at the level of statistical significance set at p <0.05. Results: The level of ownership of the Heathy Schools and Villages Program in the post-certification phase is low and associated with the negative perceptions of the community towards the Healthy Schools and Villages Program (p = 0.0294); insufficient and / or lack of financial resources (p = 0.0327); the absence / non-existence of community-based committees in some villages and schools (p = 0.0000); the lack of motivation of the members of the existing committees and the effectiveness of these committees (p = 0.0134); the insufficiency / absence of supervision of permanent monitoring of activities by the BCZ and the technical and financial partners (p = 0.0024 and 0.0286) and the low or not community mobilization in the village (p = 0.0000).Discussion and Conclusion: The low ownership of Healthy Schools and Villages Program remains a major problem in communities and the involvement of all stakeholders in the process is of great importance. Intervention projects should set up dynamic committees and motivate them, a monitoring plan and financial support while building community support in order to sustain interventions.

Hydro-agricultural management, being a tool for controlling water, is also a means implemented to carry out the irrigation operation. The general objective of this study, initiated on the rice-growing area of ​​Towéta 1, is to carry out a feasibility study of the hydro-agricultural management of a perimeter by a semi-Californian system with a view to increasing the agricultural yield of producers. To attain our goals, we used data collection techniques such as documentary research, semi-structured interviews and direct observation. At the end of the research, it appears that the management of the site by the Californian system will allow producers to, not only increase rice yields but also produce off-season market garden crops. With a surface area of 15 ha, the technical study revealed a silty-clay soil with a longitudinal slope of 1.6% and an average transverse slope of 0.8%. Regarding the development, it was proposed a development scheme with total control of water on the area with an equipment flow of 4.17l/s/ha and a water hand taken equal to 8l/s.
