Yielding fruits and palm hearts, peach palm (Bactris gasipaes) was a staple food crop for many pre-Columbian Amerindian communities in the lowland humid neotropics. The gene pool of cultivated peach palm and its wild relatives is rich in diversity but is subject to genetic erosion creating an urg...

A review]What is the relevance of smallholders' agroforestry systems for conserving tropical tree species and genetic diversity in circa situm, in situ and ex situ settings? A review

In this section we provide a more in-depth look at the role trees play in the provision of goods and services in multifunctional landscapes. Tree growth is, however, vulnerable to climate variability, depending on the physiological properties of the tree and characteristics of the site. A further...

This methodological guide was designed to help researchers and development workers to conduct a participatory analysis of vulnerability and adaptation to climate change (PAVACC) with rural communities, and to develop action plans that reflect the concerns of the rural communities. The approach he...

La vulnérabilité au changement climatique est un indicateur de sensibilité ou d’incapacité d’un système à faire face aux effets défavorables des variabilités et risques climatiques. Les communautés rurales connaissent mieux leurs situations. Elles ont leur façon de percevoir le phénomène de chang...

Providing a detailed picture of the values of trees for local people in the tropics is a difficult undertaking. Not only does this represent the difficulty in accounting for values outside formal markets, but it also reflects the multiplicity of the species involved and the many different ways in...

Understanding spatial variability of soil properties is essential to support land management decisions. However, despite the growing worldwide emphasis on integrated landscape management, soil variations resulting from land use changes have rarely been documented. The study used the land health s...

We investigated variation in age-adjusted fuelwood properties of Balanites aegyptiaca, Combretum glutinosum, Guiera senegalensis, Piliostigma reticulatum and Ziziphus mauritiana along latitudinal transects in five regions extending from eastern to western Mali. The objectives were to determine if...

Products and services provided by trees in forests and farmland support the needs and promote the wellbeing of hundreds of millions of people in the tropics. Value depends on managing both the diversity of tree species present in landscapes and the genetic variation within these species. The bene...

Anthropogenic climate change has significant consequences for the sustainability and productivity of agroforestry ecosystems upon which millions of smallholders in the tropics depend and that provide valuable global services. We here consider the current state of knowledge of the impacts of clima...
