Abstract

Unsustainable development has often threatened watershed ecology in many parts of the world, and population growth has played a major role in this process. Our study consists of the development of a watershed management plan. The degradation of environments by bushfire, timber exploitation, and firewood harvesting dew soil and pollutes spring water, in addition, there are also negative impacts on the physicochemical property of the soil. This research aims to put in place a watershed management plan to restore the soil and the soil pit against erosion. The development also allows for the protection of water resources and the pollution generated by this degradation. The study specifies the physical characteristics of the watershed: altitude, slope, and constant of Graveluis. We also examine the physicochemical properties of the soil: structure, texture, and pH. After the study of the soil, we also determined the measure of the flow of the source, the organoleptic analysis, and also the physicochemical and bacteriological analysis. The results of this work once made available to the authorities of the basic data could be exploited in the framework of the improvement of the quality of water intended for human consumption. To fight against water pollution, the easiest measure to apply is a large awareness campaign.

Abstract

Despite its socio-economic vulnerability, Madagascar has committed itself to carrying out development actions that are reflected in its National Policy. The aim of this study is to produce recommendations for decision-makers on local realities that need to be taken into account regarding the implementation of Sustainable Development Goals. To proceed, four Sustainable Development Goals or SDGs that directly concern cities have been chosen such as: SDG 6 “clean water and sanitation”, SDG 7 “clean and affordable energy”, SDG 11 “sustainable cities and communities” and SDG 12 “responsible consumption and production”. The main methodology is based on an inductive method with a multiscalar approach that starts from the study of the particular case of Ambositra, the locality chosen for this study, to express an opinion on a broader and generalized perspective of Malagasy cities' situations. These results are highlighted: low access to clean water and sanitation, outdated and inadequate public infrastructure and facilities; polluting and non-renewable energy consumption. However, opportunities exist and can be used to achieve these four objectives. Sustainable development is a long-term task which must be included into local development frameworks.

Abstract

For the conservation of the biodiversity of Ranomafana, the valorization of the aromatic and medicinal plants of Ranomafana is an alternative. Two plants of the RUTACEAE family were chosen Vepris ampody and Vepris sp. For this a multidisciplinary approach was adopted: an ethnobotanical survey for the traditional use, ecology of the plant in order to identify environmental conditions favorable to the development of the species, phytochemical screening and identification of the essential oils of the leaves, isolation of mycoendophytes and identification of the fatty acids resulting from the extracts of fermentation. Vepris ampody is used in traditional medicine, and the decoction of leaves and bark is used in case of fever, malaria, fatigue, and muscle pain. The leaves are rich in alkaloids and the essential oils in sabinene. Four strains have been isolated. After fermentation, these four strains produce fatty acids, mostly unsaturated. Vepri ssp. has no medicinal use, it is used to ward off a spell. The leaves are rich in alkaloids. The essential oil is rich in linalool. The perspectives of the study concern the popularization of culture and the identification of alkaloids.
