Résumé : The slides were taken on collecting trips sponsored by the William L. Bryant Foundation, where books, music and art indigenous to the regions were gathered. The are organized by geographical location.
By 1755, the Good Hope Estate was formed through a land grant, given to Colonel Thomas Williams, who built the first great house on the site, which was a sugar estate. In 1767, the property and surrounding estates was purchased by John Tharp, then the largest land and slave owner in Jamaica. The plantation is close to the Martha Brae River and the Cockpit Mountains. The estate became a hotel in 1912 after it was purchased by an American banker.

Résumé : International audience
Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one of the greatest disturbances to coral reef ecosystems in the Indo-Pacific, affecting not only coral reefs but also the coastal communities which rely on their resources. While injection approaches are increasingly used in an attempt to control COTS densities, most of them display severe drawbacks including logistical challenges, high residual environmental impacts or low cost-effectiveness. We tested a new alternative control method based upon acidic injections of cheap, 100% natural products. We investigated the lethal doses, intra-and inter-specific disease transmission and immune responses of COTS when injected with fresh lime juice (extracted from local Citrus arantifolia) and white spirit vinegar. High COTS mortality was achieved with small volumes: 10–20 ml per seastar induced death in 89%/ 97% of injected specimens after an average 34.3 h/29.8 h for lime juice and vinegar respectively. Highest efficiency was reached for both solutions with double shots of (2 × 10 ml) in two different areas on the body: 100% mortality occurred within 12–24 h, which is similar or faster compared with other current injection methods. Multiple immune measures suggested that death was very likely caused by pH stress from the acidic solutions rather than a bacterial infection. Contagion to either conspecifics or a variety of other reef species was not observed, even at COTS densities 15 times higher than the highest naturally reported. 10 to 20 l lime juice/vinegar could kill up to a thousand COTS at a cost of less than 0.05 USD per specimen; no permits or special handling procedures are required. We conclude that injections of lime juice and vinegar offer great advantages when compared to current best practises and constitute a cheap and natural option for all reefs affected by COTS.

Résumé : Les objectifs de développement de systèmes de culture durables imposent aux acteurs du développement rural une reconception de ces systèmes. Les méthodes de conception actuelles conduisent souvent les chercheurs à être seuls concepteurs alors que parallèlement l'appropriation des innovations dépend fortement de l'implication des autres acteurs. En réponse, des approches participatives sont de plus en plus fréquentes pour pallier à cette difficulté d'appropriation. La méthode développée dans cette thèse -nommée DISCS pour 're-Design and assessment of Innovative Sustainable Cropping Systems' - met en oeuvre un processus de reconception des systèmes de culture par une approche participative tout en développant des outils d'évaluation multicritère. La méthode DISCS s'inscrit dans la lignée de la méthodologie du prototypage mais se différencie par une démarche itérative à trois échelles d'étude (parcelle, exploitation et territoire) afin de s'assurer que les innovations répondent bien aux attentes des acteurs. A chaque étape du processus une évaluation est réalisée à l'aide d'un jeu d'indicateurs. DISCS a été testée sur le système de culture agrumicole en Guadeloupe dans un but de réduire l'utilisation des pesticides. Cinq prototypes de gestion de l'enherbement ont été conçus collectivement puis testés selon les principes d'une approche systémique. Dans cette thèse, nous présentons les premières étapes de reconception du système agrumicole guadeloupéen basée sur la méthode DISCS. Notre travail nous permet de recommander des techniques de gestion de l'enherbement en jeunes vergers d'agrumes répondant aux contraintes actuelles de développement de systèmes de culture durable.
Re-designing sustainable cropping systems has become a major challenge for agricultural researchers and farmers. In most designing methods, researchers are the main, or sometimes the only designers. However, more and more attempts for involving different kinds of stakeholders in participatory approaches have been accounted for. The new method described in this thesis (DISCS for 're-Design and assessment of Innovative Sustainable Cropping Systems') implements a participatory re-designing process. Though founded on the common structure of prototyping methods, this five-step-method differs first by implementing three progress loops, at experimental field, farm then regional scale. Besides, an ongoing progress dynamic is set between research at the experimental station and crop management in farms, in order to ensure that innovative techniques actually match the farmers' expectations. Assessment at each step is performed using a scale-specific set of indicators. The DISCS method was tested on citrus production in Guadeloupe, to develop lower-pesticide sustainable cropping systems. Five weed management prototypes were collectively designed then tested at an experimental station based on the principles of a systematic approach. In this thesis, we present the first stages of citrus cropping system redesigning based on DISCS method. Our work enables us to recommend sustainable weed management techniques for young orchards that correspond to the current constraints facing orchards in Guadeloupe
