Jaunissement Mortel du Cocotier et Mutations Sociales à Grand-Lahou, Côte d’Ivoire

Coconut farming is an important part of the Ivorian economy and governs the lives of people who grow it. However, the Lethal Yellowing Disease (LYD), occurring in the Ivoirian plantations of Grand-Lahou has undermined the foundations of the social economy and the social dynamics by their perverse effects. In order to identify the social implications of the fatal yellowing of the coconut tree, a study was conducted in ten villages in GrandLahou subject to this epidemic. The collection of quantitative data was carried out among 101 people determined by quota sampling. Qualitative survey was conducted among 10 women and 10 men all involved in the production and processing of coconut. For data managment, S.P.S.S for quantitative data and MaxQDA for qualitative data were used. The results attest to the respondents' sufficient life experience to appreciate the impact of the LYD. The consequences of the Lethal Yellowing Disease relate to the disruption of the traditional customary designation system (81.8%), the lack of local development resulting from the loss of income (15.8%) and areas of plantation plantations (83.2%), the relaxation of intergenerational relations between seniors and cadets. Despite its weak impact on polygamy as a cultural construct, the LYD participates in the transformation of gender relations which promote women's access to land and their autonomy. Ultimately, the JMC is presented as a social fact participating in the development of women but laying the foundation for a weakening of the collective consciousness.La culture du coco constitue un pan important de l’économie ivoirienne et régente la vie des populations qui la cultivent. Cependant le jaunissement mortel du cocotier (JMC), intervenu dans les plantations ivoiriennes de Grand-Lahou a sapé les fondements de l’économie sociale et la dynamique sociale par leurs effets pervers. Afin de cerner les implications sociales du jaunissement mortel du cocotier, une étude a été conduite dans une dizaine de villages de Grand-Lahou sujets à cette épidémie. La collecte de données quantitatives a été effectuée auprès de 101 personnes déterminées par l’échantillonnage par quotas. Celles qualitatives ont été réalisées auprès de 10 femmes et 10 hommes tous impliqués dans la production et la transformation de la noix de coco. Pour le traitement et l’analyse des données quantitatives, il a été mobilisé le logiciel Statistical Package for Social Sciences (S.P.S.S) tandis que l’usage de MaxQDA a été fait pour les données qualitatives. Les résultats attestent d’une espérance de vie suffisante des répondants pour apprécier l’impact du JMC. Les implications du jaunissement mortel du cocotier portent sur le bouleversement du système traditionnel de désignation de l’autorité coutumière (81,8%), l’absence de développement locale conséquence de la perte de revenus (15,8%) et des superficies de cocoteraies (83,2%), ainsi que le relâchement des relations intergénérationnelles aînéscadets. Malgré son faible impact sur la polygamie comme construit culturel, le JMC participe à la transformation des relations de genre favorisant l’accès de la femme à la terre et son autonomie. En définitive, le JMC se présente comme un fait social participant à l’essor de la femme mais jetant les jalons d’un affaiblissement de la conscience collective

Field schools and plant clinics : effective agricultural extension approaches to fight the coconut lethal yellowing disease and improve livelihoods of smallholder farmers in Grand-Lahou, Côte d’Ivoire

Annex 19 of 48 for CIFSRF-IDRC/GAC Final technical reportThis work was carried out with the aid of a grant from Canada’s International Development Research Centre (IDRC), and with financial support from the Government of Canada, provided through Global Affairs Canada (GAC)Field schools and plant clinics are key extension tools to fight Côte d’Ivoire lethal yellowing disease (CILY) that severely impacts the livelihoods of thousands of smallholder farmers in Grand-lahou, Côte d’Ivoire. This paper describes the processes in establishing and organizing field schools, plant clinics, Women Coconut Fairs and Women Groups in CILY-affected villages of GrandLahou. Land acquisition is one of the main issues that affect women within the coconut value chain in Grand-Lahou: women are denied access and control over farmland, and work at their husband’s plantations

First report of a phytoplasma affecting cassava orchards in Cote d'Ivoire

The findings suggest that cassava may be a potential alternative host for the Côte d'Ivoire lethal yellowing (CILY) phytoplasma, which poses a serious threat for the food security of smallholder coconut and cassava farmers, especially women, in Grand-Lahou, Côte d’Ivoire. Leaf samples were collected at random from 12 symptom-bearing and two symptomless cassava plants from two villages. Illustrations/ figures depict the symptoms of yellowing. Cassava (Manihot esculenta) is one of the staple foods in Africa, cultivated in 40 countries and producing more than three million tonnes per year

This detailed paper is part of a larger study “Fighting lethal yellowing disease for coconut farmers (CIFSRF Phase 2)” and was carried out with surveys in eight coconut-growing villages of Grand-Lahou to assess the differential detection of the CILY phytoplasma in the stem, inflorescences and leaves of affected palms, as well as to render a phylogenetic analysis. Disease stages one, two and three were present throughout all the coconut plantations of the surveyed villages

CIFSRF final technical report : Fighting lethal yellowing disease for coconut farmers (CIFSRF Phase 2)

Annexes cataloged separatelyThis work was carried out with the aid of a grant from Canada’s International Development Research Centre (IDRC), and with financial support from the Government of Canada, provided through Global Affairs Canada (GAC)Côte d'Ivoire lethal yellowing (CILY) has impacted farmers' family nutrition and limited women’s income in Grand-Lahou. It was anticipated that CILY would decimate the Ivorian coconut grove by 2020 if prompt actions were not taken. Therefore, the general objective of the research was to provide and communicate new needed information to allow authorities, policy makers, stakeholders and farmers to better control CILY. The overall progress of project implementation and outcomes contributed to provide that information, which became innovative knowledge contributions and gender-responsive solutions to engage famers, stakeholders and policy makers in addressing the disease problem

Without urgent action, the disease will decimate coconut crops by 2020. CILY is associated with phytoplasmas, insect-transmitted organisms that devastate various crops worldwide. Through field schools, plant clinics, and workshops, the research team will transmit innovations to farmers, government organizations, coconut processors, and business groups. Training and support for women will help them protect their crops and strengthen their role in coconut production and processing

The phytoplasma identified was further characterized based on the sequences of the 16S rRNA and secA genes. Results support possibility of disease spread from the neighbouring Ghana, posing a threat for the Ivorian coconut industry

Detection and identification of the coconut lethal yellowing phytoplasma in weeds growing in coconut farms in Côte d’Ivoire

Annex 4 of 48 for CIFSRF-IDRC/GAC Final technical reportThis work was carried out with the aid of a grant from Canada’s International Development Research Centre (IDRC), and with financial support from the Government of Canada, provided through Global Affairs Canada (GAC)Given the high prevalence of weed species on most coconut farms, plants growing within and in the periphery of five selected farms were assessed for the presence of the Côte d'Ivoire Lethal Yellowing disease (CILY) phytoplasma to identify potential alternative hosts. Phytoplasmas are cell wall-less prokaryotic intracellular plant pathogens belonging to the class Mollicutes, and have induced the decimation of thousands of coconut groves. This paper outlines collection, gene analyses and identification of plant families that may carry the phytoplasma, suggesting these contribute to disease spread in coconut farms in Grand-Lahou, Cote D’Ivoire
