Anthracnose disease is one of the main major biotic constraints to the marketing of mango in Côte d'Ivoire. The objective of this work is to report on the distribution of mango anthracnose disease in the mango production basin in northern Côte d'Ivoire. This study focused on 740 mango trees spread over 20 orchards, consisting mainly of the Kent variety. These orchards are located in three (3) study locations, namely the Bagoué, Tchologo and Poro regions. The study consisted of evaluating the incidence and severity of anthracnose in leaf, fruit and branch organs of 740 mango trees in 20 orchards in the three study regions.

In Côte d’Ivoire, agriculture is mostly rain-fed. As a result, changes and variations of climate have considerable impacts on crops production including cotton production. This paper focuses on analyzing the effects of rainfall variations on the cropping season (useful rain season) of cotton in cotton production area of Côte d’Ivoire. A set of stationarity tests was applied to the Nicholson index using rainfall data of the period 1950-2000. Then, from a frequency analyses, the variability of rainfall and characteristic parameters of the cropping season was evaluated in terms of risks. The result shows a general downward trend of rainfall in the cotton growing area with years of breaks between 1964 and 1975. Moreover, spatial evolution of the cropping season parameters is a function of latitude. After the years of breaks, the beginning and the end of the cotton cropping season, which became respectively later and earlier, indicated that the length of useful rain season became shorter. The deficits of seasonal rainfall accumulations vary up to 60%. It is therefore necessary to update the crop calendar by taking into account variability of parameters of the useful rain season.

The tchapalo, traditional Ivorian beer, formerly produced in northern Côte d'Ivoire, has overflowed the geographical limits of its production. Its consumption is becoming more momentum in Abidjan. For a better knowledge of actors and a valorization of this beverage, this work was conducted through a survey of 385 brewers and 77 tchapalo consumers selected in 3 areas of Abidjan. Results showed that tchapalo is produced exclusively by Burkinabe women (45.5%) and the Ivorian women came from northern part of Côte d'Ivoire (53.2%), mainly women of the Lobi ethnic group (90.2%). Tchapalo production was a significant source of income for these women. The biggest consumers of tchapalo came from the Akan ethnic group which represented 52.5% of respondents. Because of its financial accessibility (300 CFA francs per liter), tchapalo is consumed by all socio-economic and professional groups, particularly foremen (41%) and laborers (31.7%). Consumers who found therapeutic principles to the tchapalo represented 54.3% of respondents. Furthermore, over 95% of respondents preferred to consume into tchapalo production area to meet friends and also to maintain fraternity links with brewers. However, 25.7% of consumers chose to consume in a specific tchapalo production area for the taste of the beverage and 25.5% due to welcome that their reserves the producer. Favorite consumption moments were afternoons and evenings.

The Sassandra Basin, like most regions of Côte d'Ivoire, is increasingly affected by droughts that involve many environmental, social and economic impacts. This basin is full of several amenities such as hydroelectric dams, hydraulic and agricultural dams. There is also a strong agricultural activity. In the context of climate change, it is essential to analyze the occurrence of droughts in order to propose mitigation or adaptation measures for water management. The methodological approach consisted initially in characterizing the dry sequences by the use of the SPI (Standardized Precipitation Index) and secondly in determining the probabilities of occurrence of successive dry years using by Markov chains 1 and 2. The results indicate that most remarkable droughts in terms of intensity and duration occurred after the 1970s. A comparison of Markov matrices 1 and 2 between the period considered 1953–2015 with the periods 1953–1970 and 1971–2015 shows a profound change in the distribution of droughts at the different station. Thus, the probability of having two successive dry years is greater over the period 1970–2015 and is accentuated to the Southern and Northern regions (probabilities ranging from 71% to 80%) of the basin. Over the 1970–2015 period, the probability of obtaining three successive dry years is significantly high in this watershed (between 20% and 70%).

As in all cashew producing areas, anthracnose causes enormous production losses in cashew agroforestry farms in Côte d'Ivoire. To overcome this problem, the use of anthracnose-resilient production plant material in cashew forest agrosystems is becoming a necessity for sustainable development. Thus, this study was carried out with the aim of evaluating the behavior of genotypes of cashew trees cultivated in peasant agroforestry systems in the north of Côte d'Ivoire. To do this, peasant agroforestry cashew orchards were prospected, cashew trees were marked, codified and geolocated. The incidence and severity of anthracnose were then assessed on the marked and geotagged cashew leaves, twigs, inflorescences and fruits. Descriptive analysis of the incidence and severity data revealed that more than 50% of the genotypes studied are resilient to anthracnose with an incidence on nuts in the order of 0.00 ± 5.75%. The ACP explained 52.96% of the total variability observed with the first two axes. The CAH made it possible to structure these genotypes into four groups. MANOVA showed that genotypes in groups 2 and 4 exhibited traits of resilience against anthracnose disease. Group 2 was characterized by a relative absence of disease in the fruits (0.00 ±0.00) and by very severe infections in the twigs (88.19 ± 2.98). Groups 4 were differentiated by low fruit infections (1.32±0.32) and low incidence on fruits (2.17±1.09). These results should help promote the agroecological management of anthracnose disease, enhance and intensify agroforestry practices in Côte d'Ivoire.

Using Data

The rainfall and temperature conditions are evaluated for the first time during the 1989–2006 period, in six main cocoa production areas (Abengourou, Agboville, Daloa, Dimbokro, Guiglo, and Soubre) of Côte d’Ivoire using data from SODEXAM (ground-based observation) and the ex-CAISTAB. Statistical analysis shows an important sensitivity of cocoa production to rainfall conditions in all regions. It is worth noting that only the major rainy season from April to July and the rainfall amount of the little dry season from August to September affect the cocoa production for an 80% confidence level. This influence varies from one cacao production area to another. Moreover, the effects related to temperature on the cocoa yield seem to represent a smaller contribution of climate impact than those related to precipitation during the studied period. The temperature change remains in the acceptable range of values, between 25°C and 29°C, which is a favorable condition for cocoa growing. These findings are obtained despite the significant contributions from nonclimatic factors, to year-to-year variability in cocoa production.

Cashew Tree

Cashew cultivation faces several health problems. Among these problems, anthracnose causes extensive damage to twigs, leaves and fruits and causes loss of yield. The spread of this disease is thought to be determined by certain agromorphological features of the cashew tree. The objective of this study was to search for these agro-morphological determinants that influence the spread of anthracnose disease in agroforestry systems in Côte d'Ivoire. To achieve this objective, 30 cashew trees spread across 26 agroforestry cashew orchards in the Korhogo, Sinématiali and Boundiali departments were chosen and geolocated. The factor studied was the clone, consisting of 30 cashew genotypes, with 15 modalities. The collected data was subjected to descriptive analysis, correlation test, PCA and hierarchical ascending classification (CAH). The results showed that the wingspan, leaf area and size of cashew trees are determinants that promote the spread of anthracnose disease. Following this result, the CAH made it possible to screen the genotypes into three groups. These results could contribute to management of anthracnose disease in agroforestry, to enhance and intensify this cropping systems.
