Plants constitute a precious resource and a true treasure for humanity. They play an important role ecologically, economically and socially. Plants produce oxygen, they regulate the climate, they purify water, they provide food, they provide health benefits.
this study, on the one hand, makes an inventory of the species of medicinal plants encountered in the botanical garden of Eyale and on the other hand, it presents their impacts on the indigenous peoples (the pygmies) of the city of Mbandaka in the DRC.
Floods are sources of natural disasters around the world. They occur following flooding of rivers and an overflow of urban sanitation drainage routes.
This impressive phenomenon causes enormous losses in the ecological, economic and social sectors. According to current statistical data (2010-2020), floods caused more than five million victims worldwide (OCHA, 2022). Obviously this, without taking into account the other effects: material damage, service disruptions, health risks, famine, psychological trauma, etc.
Faced with the intensification of these phenomena in Kinshasa, thanks to scientific investigations carried out in the field, this study proposes integrated strategies likely to contribute to the sustainable prevention of flooding in the lower part of the city of Kinshasa. This approach will be accomplished in response to the Sendai Action Plan (2015-2030) which wants scientists to become deeply involved in the quest for sustainable prevention of natural disasters in their societies.
In the Democratic Republic of Congo, lake ecosystems, absolutely necessary sources, in particular for the production of fishery resources, are today threatened by both artisanal and industrial overexploitation. This overexploitation is a serious threat to the ecological balance, environmental protection and maintenance of the biodiversity of these aquatic ecosystems. This study, which falls within the framework of nature conservation and environmental education, seeks to understand in a multidimensional vision how the young students of the Higher Pedagogical Institute of Inongo identify, analyze and measure the importance of these ecological problems that cause the degradation of the environmental health of Lake Mai-Ndombe. The results of this study will be able to guide the national authorities in their decision to integrate the course of ecology into the undergraduate program at the University. Because the quality of the environmental governance of Lake Mai-Ndombe in the future depends on it.
Urban ecology is a source of hope for the urban planning of the future, we can say that this discipline and its practices are innovative in the realization of the project of sustainable cities. Indeed, like ekistics, urban ecology also fits, prima facie, in the spirit of the Athens Charter (1933) and Agenda 21 (1992) by their aim modernist of the city and by their push for the start of the greening of our current cities for a sustainable urban future. Unfortunately, urban ecology in Africa, particularly in the Democratic Republic of Congo is confronted with several predictable or unpredictable situations which complicate its task in its mission of achieving the sustainable city. These challenges include: poverty, uncontrolled population growth, the failure of regulatory information and poor governance, etc.Faced with the various forms of vulnerabilities, it is urgent today to think of a sustainable development of these urban areas.
Devant la crise écologique à laquelle se trouve confronter l’humanité, des hypothèses sont émises dans beaucoup de disciplines, en outres, le récit biblique pour décrypter la responsabilité de l’homme dans cette crise écologique. Ainsi, en nous servant de l’encyclique « Laudato si , 2015 » du Pape François, nous voudrions nous intéresser à l’analyse de ce document afin de voir dans quelle mesure l’homme est à la base de la crise écologique. En suite, proposer des solutions au problème de cette crise qui menace l’équilibre durable de notre Planète Terre, la mère nourricière des humains, des générations actuelles et futures.
This paper analyses the urban metabolism of Kinshasa and forms on self- relience (resilience) socio-economic strategies as responses to socio-environmental vulnerability.
Based on house hold survey, results revealed that with more than 80% of people are jobless, many families survival depends on resilience strategies in Kinshasa. This situation cannot boost the urban city sustainability. Some appropriated strategies should be promoted to ease the access to good education, health care facility, decent living, good transport, good nutrition and good public income, etc.
Otherwise, the urban environment will be harmful, not sustainable, and the 21 st Century sustainable City will remains a dream.
