Résumé : Vegetation phenology is the study of the timing of seasonal events that are considered to be the result of adaptive responses to climate variations on short and long time scales. In the field of remote sensing of vegetation phenology, phenological metrics are derived from time series of optical data. For that purpose, considerable effort has been specifically focused on developing noise reduction and cloud-contaminated data removal techniques to improve the quality of remotely-sensed time series. Comparative studies between time series composed of satellite data acquired under clear and cloudy conditions and from radiometric data obtained with high accuracy from ground-based measurements constitute a direct and effective way to assess the operational use and limitations of remote sensing for predicting the main plant phenological events. In the present paper, we sought to explicitly evaluate the potential use of MODerate resolution Imaging Spectroradiometer (MODIS) remote sensing data for monitoring the seasonal dynamics of different types of vegetation cover that are representative of the major terrestrial biomes, including temperate deciduous forests, evergreen forests, African savannah, and crops. After cloud screening and filtering, we compared the temporal patterns and phenological metrics derived from in situ NDVI time series and from MODIS daily and 16-composite products. We also evaluated the effects of residual noise and the influence of data gaps in MODIS NDVI time series on the identification of the most relevant metrics for vegetation phenology monitoring. The results show that the inflexion points of a model fitted to a MODIS NDVI time series allow accurate estimates of the onset of greenness in the spring and the onset of yellowing in the autumn in deciduous forests (RMSE <= one week). Phenological metrics identical to those provided with the MODIS Global Vegetation Phenology product (MDC12Q2) are less robust to data gaps, and they can be subject to large biases of approximately two weeks or more during the autumn phenological transitions. In the evergreen forests, in situ NDVI time series describe the phenology with high fidelity despite small temporal changes in the canopy foliage. However, MODIS is unable to provide consistent phenological patterns. In crops and savannah, MODIS NDVI time series reproduce the general temporal patterns of phenology, but significant discrepancies appear between MODIS and ground-based NDVI time series during very localized periods of time depending on the weather conditions and spatial heterogeneity within the MODIS pixel. In the rainforest, the temporal pattern exhibited by a MODIS 16-day composite NDVI time series is more likely due to a pattern of noise in the NDVI data structure according to both rainy and dry seasons rather than to phenological changes. More investigations are needed, but in all cases, this result leads us to conclude that MODIS time series in tropical rainforests should be interpreted with great caution. (C) 2013 Elsevier Inc.

Description : Ce document recense toutes les interventions qui ont eu lieu lors de la réunion annuelle de la Caribbean Food Crops Society. Ces interventions ont pour objet le développement des cultures vivrières, la lutte contre les nuisibles, le compostage, les systèmes d'agro-écologie, l'utilisation des ressources biologiques tropicales... Elles s'appuient sur des expérimentations effectuées dans différents pays de la Caraïbe (voire d'autres pays tropicaux). Les changements météorologiques, la dépendance alimentaire, la croissance démographique obligent la Caraïbe à se lancer dans la transition agroécologique et énergétique, en lien avec les nouveaux défis adressés par l?émergence de la bioéconomie.

In Trinidad and Tobago, cocoa production is monitored by the Cocoa and Coffee Industry Board, which was established in 1961. Cocoa, used to make chocolate, is a traditional export crop in the country. Buildings like those pictured would be used for processing, drying, sorting, and storing cocoa beans. In this image, several children and adults can be found in the yard near buildings on the cocoa plantation. The buildings are made with wood and have zinc paneled roofs, some of the steps are made of concrete. The level flat area between the buildings on the far right would be used to dry cocoa beans. The beans would be spread out evenly on this area, then raked and turned so that beans were exposed to the sun for adequate drying. Slide labeled Cocoa Plantation Trinidad.
