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...

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...

In this final section we will discuss the interrelationships among people, trees and local climate (the inner circle of the diagram), and all the surrounding issues at national and international levels, and then relate our current understanding and knowledge of these interrelations to opportuniti...

Partly due to severe lack of instrumental climate data, the drivers of the African climate, their interactions and impacts are poorly understood. The paper demonstrates the prospects and applications of dendroecological and stable isotope techniques, such as to reconstruct climate variability, tr...

The relationships between annual wood stable carbon isotope composition (δ13C), dry season midday plant water potential, and annual growth rate were investigated to asses the ability of agroforestry species to adapt to climate changes. 6–8 stem disks from four co-occurring species (Acacia senegal...

Tree rings and stable isotopes in tree rings provide evidence of past climate variability. Given the short instrumental climate records that exist in Africa, dendrochronology adds an essential longer-term perspective on climate change and variability and on the adaptation of agroforestry landscap...
