Повний текст джерелаThe witches’ broom disease (Crinipellis perniciosa) is a fungal infection which only affects the meristematic plant tissues of the cocoa tree. To date it has been restricted to the Latin American continent. The aim of this work was to examine scientifically the measures undertaken in the Alto Beni region in the humid tropical lowlands of Bolivia, to curb the witches’ broom disease (Crinipellis perniciosa) by phytosanitary pruning measures and by the use of various tolerant clones From 1994 to 97, the cocoa clones ICS 1, ICS 6, ICS 8, ICS 95 and TSH 565 were also studied under field conditions at the Sapecho location for witches’ broom tolerance and yield. In addition, various pruning frequencies were examined for their efficiency with regard to the yields of the clones and the effects on witches’ broom infection The results show a connection between rainfall levels and the formation of basidiocarps on the witches’ broom. However, over the whole of the investigation period, no causal connection was found between the intensity of basidiocarp production on the witches’ broom shoots and the number of witches’ broom infections on the trees under investigation. The five clones showed significant differences both in relation to their susceptibility to witches’ broom and in their yields. The different pruning frequencies, on the other hand, did not show any statistically provable differences in terms of the number of witches’ broom infections, nor did they influence the yields. It has become clear that neither the own studies nor the many research works undertaken at an international level were able to find a fundamental solution to the witches’ broom problem. Agriculture using the principles of successional agroforestry systems could represent a long-term perspective for land use in these areas, with the emphasis on more than short-term economic, social or structural objectives.

Повний текст джерелаIn Ivory Coast, where 40% of world cocoa beans are produced, most forests have been converted into cocoa plantations. After a century of expansion, this crop and its producers are facing with a new environmental situation, here called « post-forest conditions ». Firstly, forest cover has almost completely disappeared ; secondly, monocultures are showing their limits (pests attacks, productive lifelenght shortened) ; and finally recent climatic evolutions are less suitable to this crop (Bigot et al., 2005). The conjunction of these different elements has led to a « structural blockage » (Leonard and Oswald, 1996). In cocoa history, when such situation occurs another country or region would take over the area in crisis for cocoa production (Ruf, 1995). This PhD studies adaptation strategies, especially agroforestry ones, of cocoa farmers and depicts a possible bifurcation from the universal boom and busts model. It is based on botanic inventories, farmers interviews, multichronic land use maps (1956-2017) and two monographies. Farmers agroforestry practices are analysed at environmental and socio-political data crossroads on four sites representative of different stages of cocoa history (from East to West : Akoupé, Divo, Guéyo and Méagui). Main results are the following : 1.Studied cocoa plantations are very diverse from systems close to monocropping to dense and multi-stratified agroforests. In the sample studied, 22 % of the 137 studied plots have agroforestry caracteristics. 2.The assessed environmental contributions (biodiversity, aboveground carbon stocks, timber, food use, medicinal use and agronomic contributions to cocoa trees) differ from forest ones. However, farmers management of trees origins (remnant, recruited or planted) shapes agroforests capacity to provide these contributions. 3.Since a decade, there is a trend of densification and diversification of associated trees in cocoa plots. Through the comparison between speeches and practices one can consider that 67% of farmers have an attitude favorable to associated trees. 4.Farmers « post-forest » strategies are diverse, from abandoning cocoa to chemical inputs use or ecological intensification, they include several agroforestry systems and are witnesses of a general will to maintain cocoa production activities in post-forest conditions. 5.Adopting agroforestry strategies appears as an answer to land scarcity situation at household and village scale. 6.Finally, these evolutions of cocoa growing open the needs for new ressources. Governance conflicts about these ressources appropriation at local, regional and national scale are the main obstacle to agroforestry adoption and success. Through a transdisciplinary approach, this geography PhD illustrates the relationships that bounds cocoa producers and post-forest environment
