This prototype measure several weather data: temperature, relative humidity, wind speed, wind direction, rainfall. For further data analysis, these are transmitted for recording to a remote server via wireless communication. The server offers data extraction possibilities in multiple file formats. A prototyping of the personal weather station is designed and commissioned. An extract of the results over two days is presented in the results section of this document

The objective of this study was to develop a low cost and efficient water defluoridation filter using local materials. The filter frame was made from Polyvinyl chloride pipe of 125 mm diameter and 1 m height, with a useful filtration volume of 9.55 l. The filtration layer consisted of a sequence of three strata: gravel, bone-char and sand, giving a total weight of 15 kg. Based on the concentration of fluoride in drinking water in parts of northern Cameroon, three different fluoride ion concentrations (10 mgl-1, 20 mgl-1 and 30 mgl-1) were prepared in the laboratory using distilled water and allowed to flow through the filter at the rate of 3.33 lh-1. High fluoride uptake capacity was observed (94.8% to 99.1%), depicting the suitability of the filter in defluoridation. The constructed filter costed about 17 US$. Based on these results, the fi...

The objective of the study was to assess the role of FOs in the reinforcement of the economic capacities of farmers in the region. Secondary sources data were reviewed while primary source data were gotten directly from farmrs in the field. Two hundred and eighty (280) farmers’ members of these FOs were interviewed using a semi-structured questionnaire and 7 leaders were interviewed using an interview guide. In addition, direct observations were made. The data collected were analyzed using SPSS. The findings show that, 18.57% of the respondents who possessed agricultural equipments in their farms from the support of SOS Faim/EC, 17.14% as a result of MINADER support, 20% as a result of ACEFA support and 44.28% coming from the farmer...

En prélude à l'élaboration d'une stratégie de gestion durable de l'eau du sous-bassin, un état de lieux a été réalisé et les effets des variations climatiques sur les ressources en eau analysés. Les données climatiques sur la période 1978-2008, les données secondaires des études antérieures et les données des prélèvements en eau effectués par la Camerounaise des Eaux ont été analysées. Ces données ont été complétées par des informations observées sur le terrain et collectées lors des entretiens avec des acteurs clés. Les ressources naturelles en eau de surface ont été estimées à 24 Mm3. Seulement 2% des eaux de surfaces sont prélevées (0.48 Mm3), tandis que la capacité du seul réservoir dans le bassin est de 0.45 Mm3. Il y a un potentiel d’usage pour la production hydroélectrique en aval du réservoir. La qualité microbiologique du lac laisse à désirer pendant c...
