  • Climate Change Vulnerability Assessment through Coping Strategies Index in Tillaberi region in Niger

    Climate change vulnerability of four villages in the Tillaberi Region of Niger was analyzed through a coping strategy index (CSI) determination. It concerned the villages of Dioga and Magou, in the commune of Torodi and those of Zori Bangou and Tokobinkani Zarma in that of Hamdallaye. Two types of indices were measured, one in relation to food security, and the other with assets and livelihoods. They reflected different values between the villages of the two municipalities and the two municipalities from 2015 to 2106. The value of the CSI in relation to the food security of the two municipalities in 2016, represents half of the score 2015, reflecting a decline in food vulnerability for this period. The CSI for assets and livelihoods for 2016 is 6.93, higher than 2015 one (6.32), indicating a greater diversification of livelihoods. In addition, the coping strategy index for the food aspects is higher in the villages of Hamdallaye with 55.5 and 41.9 respectively in 2015 and 2016, than in those of Torodi respectively 46.91 and 22.6, for 2015 and 2016, reflecting a higher vulnerability in Hamdallaye. For the CSI in relation to the assets and livelihoods, there is no significant difference between the two villages of Torodi and one of the two villages of Hamdallaye (Zori Bangou). Torodi, located further South with higher rainfall and greater livelihood diversification, has lower vulnerability criteria in relation to the food aspects than Hamdallaye in the north. Thus, there is an increase in vulnerability from south to north inversely proportional to the increasing rainfall gradient.

  • Evaluation of the quality of beeswax from different sources and rendering methods

    Most of the wax produced now-a-days are used in the manufacture of cosmetics, such as hand and face creams, lipsticks and depilatory wax and many uses. To become competent both in local and export markets the quality of the beeswax has to be maintained. However pre- and post-harvest handling and processing of crude beeswax may affect its quality and quantity. Hence, the objective of the present study was to evaluate the quality and quantity of beeswax obtained from different sources and compares the effectiveness of different beeswax extraction methods for rendering pure and quality beeswax. Three bees wax sources (comb, sefef and crude honey) and three extraction methods (manual, submerged and solar) were arranged in complete factorial in Randomized Complete Block Design (RCBD) with three replications. Ten kg each of comb, sefef and crude honey were used for extraction and the average amount of pure beeswax obtained was compared. The analysis of variance indicated that there were significant difference among beeswax sources, extraction methods and interaction between beeswax sources and extraction methods on the yield of beeswax and slum gum ((P
