Cashew Apple

In Côte d'Ivoire, cashew apples represent waste in plantations due to lack of processing. This study deals with their transformation into jam for a better valorization. Cashew apple jam were analyzed for physicochemical and sensory properties. Proximate physiochemical were determined using standard analytical procedures and the sensory acceptance test was performed by 50 panelists on the following attributes. Proximate result showed that moisture content of cashew apple jam was 26.5±1.77% ; carbohydrate 67.7±02.45%, protein 0.7±0.01%; fat and ash contents were 0.16±0.0 and 2.4±0.01% for respectively. pH and titratable acidity were 3.9±0.01 0.06% respectively. Soluble solids (°Brix) was 25±0.98%. Vitamin C and total sugar contents were 276±4.67 (mg/100g) and 51.87±2.18% respectively. Major minerals in the jam were potassium (2762±43.2 mg/Kg), phosphorus (298±4.1 mg/Kg), magnesium (146±1.1 mg/Kg) and calcium (143±2.21mg/Kg). phytochemical analysis revealed presence of tannins (0.8±0.01%), phenol (0.35±0.02%), oxalate (1.87±0.02%) carotenoids (0.70±0.01%), flavonoid (0.20±0.01%), phytate (1.16±0.03%) Results from sensory analysis showed color (7.88±0.55), consistency (8.22±0.83), sweet (8.44±1.09) odour (5.4±0.36) and general acceptability 5.22. Parameters (acidity, astringency and afteraste) scores are less than 3.

Fire Activity

Biomass burning has become more frequent and widespread worldwide, with a significant proportion occurring in tropical Africa. Fire dynamics have been generally studied at global or regional scales. At local scale, however, fire impacts can be severe or catastrophic, suggesting local analyses are warranted. This study aimed to characterise the spatio-temporal variations of vegetation fires and identify the main fire hotspots in Côte d’Ivoire, a country of West Africa, one of the world’s burn centres. Using MODISderived fire data over a 10-year period (2007–2016), the number of fire days, active fires and fire density were assessed across the entire country. In the southern part dominated by forests, fire activity was low. Three main fire hotspots were identified between 2°30’–8°30’W and 7°00’–10°30’N in the North-West, North-East and Central areas all dominated by savannas. In these areas, Bafing, Bounkani and Hambol regions recorded the highest fire activity where fire density was 0.4±0.02, 0.28±0.02 and 0.18±0.01 fires/km²/year, respectively. At national scale, the annual fire period stretched from October to April with 91% of fires occurring between December and February, with a peak in January. Over the decade, there was a decreasing trend of fire activity. Fire density also was negatively correlated with rainfall >1000 mm for the synchronic analysis, whereas fire density was positively correlated with rainfall in the previous years. Results suggest that the positive relationship between the previous year’s rainfall and fire activity could operate on a cycle from 1 to 4 years.

The North-East region (Bounkani) of Côte d'Ivoire is the least watered region of the country with an average annual rainfall of 945 mm. The rainfall deficits observed in Côte d'Ivoire since 1970s could constitute a real threat to the environment and to water resources in general, and to dam lakes in particular. The main aim of this study was to follow the evolution of the dam lakes in the region over the years, i.e,(1986, 2002 and 2017) with reference to their spatial distribution (their densities and their limnological ratios). The approach adopted consisted of mapping and monitoring through remote sensing technology which involves processing satellite images for automatic extraction of these agropastoral structures on the various images. The results showed that these dam lakes were unevenly distributed both at the level of the departments and the watersheds, with 73.43% in the Black Volta and 28.57% in the Comoé. The density was higher in Doropo and varied from one department to another from 1986 to 2017, for the department of Bouna, it ranged from 9.34.10-4 to 3.74.10-3 per km2. The departments of Doropo and Tehini showed 1.51.10-3 to 1.01.10-2 per km2 and 1.05.10-3 to 4.53.10-3 per km2 respectively. Nassian department displayed a value of 1.42.10-3 per km2 and remained constant from 2002 to 2017. Like the density, Doropo Department had the highest limnological ratio which changes from 7.09.10-5 to 2.71.10-4 per km2 over the same period. The mapping of these agropastoral structures showed 18 agropastoral structures where 57 (28.07%) were functional or even contained water in the dry season in the region in 2017 including 2 in Nassian; 4 in Tehini; 9 in Doropo and 3 in Bouna.

Based on an inquiry on the ground and geostatistics prossessing, this task analyses the problematic of aridity and the perception done by the peasant populations of the ‘’ North -East quarter’’ region of IVORY COAST. We come to know from these analyses that the dryness is a reality in this part of IVORY COAST. Indeed, starting with the indexes of NICHOLSON and MC KEE that is the test of PETTIT and the monthly climatic balance, agricultural and meteorological dryness have been determined to all the studied stations. Mainly the meteorological dryness is much more intensive in this sector of BOUNA and DABAKALA. As to agricultural dryness, it has been heavier in BOUAKE,KATIOLA, DABAKALA and BOUNA respectively. The test of FISHER has justified the variation of the dryness apprehension in the space. Thus, the dryness can be grasped by different ways (four ways) according to the inquired places. However, the peasant populations cannot distinguish the differences between meteorological and agricultural dryness clearly.

The Impact

The objective of this research is to evaluate the impact of the orientation of a building, built in clay brick, on the temperatures of its faces, to determine the best orientation that maximizes building ventilation and minimizes overheating. We first performed a climate analysis of the site using the consultant climate software, then we have evaluate the temperatures of each face using a dynamic thermal simulation. The analysis indicates that in order to benefit from good ventilation, the building should be oriented along the Southwest face; and that an orientation along the South face would reduce the exposure of the building to sunshine. Also, numerical evaluation shows an overheating of about 4° C between the South and North faces; and about 2° C between the East and West faces. In addition, the South, North, East and West faces reach maximum temperatures of 34.75° C, 38.5° C, 40.25° C and 42° C respectively. The choice of an orientation can induce overheating from the wall, up to 7.25° C. A joint analysis of these two results leads to the conclusion that the best orientation for a building in Côte d'Ivoire is the South direction.

AbstractSweetpotato is cultivated in all the regions of Côte d’Ivoire for consumption and as a source of income. Only varieties with white or yellow flesh are grown. Production of nutritious orange-fleshed sweetpotato (OFSP) is hampered by the lack of genetic resources and planting material. To evaluate and release OFSP varieties, on-farm demonstration tests were conducted with women farmer groups in Bondoukou, Nassian, Korhogo and Bondiali in the north and northeast Côte d’Ivoire. Six varieties- ‘Kabode’, ‘Kakamega7’ (‘Irene’), ‘Tacha’, ‘Bela Bela’, ‘Vita’ and TIB-440060-were evaluated in comparison with locally grown varieties. The on-farm demonstration was laid out in a randomised complete block design with replicated three times per location. Assessments were made on yield, disease and pests; and consumer preference on attractiveness of skin color and flesh of the root (fresh and boiled), taste, texture and starchiness. Results showed that introduced varieties have generally recorded higher yields than the local varieties: Yields of about 25 t/ha have been recorded on the sites. The best average yield of about 15 t/ha, was recorded for TIB-440060 and ‘Irene’ varieties. Farmers’ acceptance of OFSP varieties based on the attraction of their color, the dry matter content and taste was more than 90%. At the end of the sensory tests, ‘Irene’, which achieved the best compromise between all observed and measured parameters, was most appreciated and was the farmers’ first choice, followed by varieties TIB-440060 and ‘Bela bela’.
