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 These results are highlighted: low access to clean water and sanitation, outdated and inadequate public infrastructure and facilities; polluting and non-renewable energy consumption.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

Almond powder of Irvingia smithii has been incorporated, at the doses of 25 and 50 %, in mice standard ration (prepared by Matadi mill), at INRB, composed of wheat flour, wheat bran and pellets for rabbits to evaluate weight gain, live weight gain and feed conversion and to assess motor activity after 50 days of feeding. Results showed an average increase in live weight gain of 31.08% and 8.36% for the groups of mice fed food supplemented with Irvingia smithii almond powder respectively at 25% and 50% higher than the group of control mice fed exclusively with the standard food. On the other hand, the food consumption index (F.C.I) was very low for the group of mice fed with the food supplemented at 50% (F.C.I. 27.73) and low for the group of mice fed 25% supplemented food (F.C.I. 64.83) compared to the control group (F.I.C. 108,14). In addition, the groups of mice fed the supplemented food did not show motor weakness, even fewer respiratory complications or health problems compared to the control during these 50 days of observation. Live weight gain sufficiently demonstrates the nutritional value of the kernel of I. smithii.

Abstract

Ecological charcoal is coal produced from biodegradable residues rich in carbon, mainly from agricultural residues. This charcoal has been obtained with different operations such as carbonization, molding and compacting to obtain briquettes. To ensure the quality of the coal, several analyses were carried out in the laboratories. The physicochemical characteristics such as moisture content, ash content, fixed carbon content; volatile matter index and lower calorific value are analyzed to better exploit their uses. Its exploitation has many advantages especially in the field of health and environment, especially for the reduction of deforestation and air pollution. This research gives 5 varieties of ecological coal obtained by the valorization of agricultural waste in the region of Vakinankaratra, a region located in the highlands of Madagascar and known for its high potentiality in agriculture and livestock. It is about the valorization of rice straw, rice husk, corn straw, banana peelings, and soybean stalks.

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.

Abstract

A study was conducted at Gbado-Lite city to assess the capacity of plantain macro-propagation by applying the PIF technique. To do this, the fragments of three types of banana trees: French, true horn and false horn were sown in a propagator containing sawdust. After germination, the seedlings were transplanted into polyethylene bags containing a mixture of clay and potting soil and installed under the shadehouse. With regard to the results obtained and statistical tests (at the 5% threshold), the significant difference between these three types of banana trees was only observed for the number of seedlings emitted by explant, the number of suckers weaned, the height of the plants at weaning and the mortality rate of plants in the nursery. Thus, emergence having taken place 2 weeks after sowing, after 46 days after resumption and 61 days after sowing, the French type was significantly different from two others with an average of 6 seedlings emitted and 4 suckers weaned per explant; the true and false horn being tied with 5 seedlings and 3 weaned suckers per explant. As for the height of the plants at weaning, the true horn (19.9 cm) was significantly higher than the other two (French: 17.7 cm and false horn: 19.6 cm). Finally, with 1.1% for True horn had a significantly lower mortality rate for plants in the nursery than the others (6.7% for French horn and 3.8 % for False horn). Although, the PIF technique influenced the suckering in a way strongly dependent on the cultivars, it can be popularized for these three types studied in order to promote banana cultivation in the agro-ecological conditions of Gbado-Lite.

Abstract

The purpose of this study was to investigate the factors that affect red chili farming's income in the village of Maligas Bandar, Simalungun Regency. This study's population consisted of forty red chili farmers. Quantitative descriptive research was used in this study. The results found in this research variable influence the production of red chili significantly in Maligas Bandar Village, Gunung Malela District, Simalungun Regency. According to the findings of the analysis, the variable land area (X1), seeds (X2) and fertilizer (X3) had a significant impact on the production of red chili or the variable (Y). The results of the calculation of R2 explain 0.850% or 85%. While the remaining 25% are variables not included in this study.
