Impact of human land-use and rainfall variability in tropical dry forests of southwest Madagascar during the late Holocene by Razanatsoa, Estelle

“…Therefore, it provides a perfect setting to generate new palaeoecological records and investigate vegetation response to changes in human land-use and rainfall variability. The aim of this thesis is to understand how and when land-use changed, and rainfall variability impacted the landscape in the southwest region, using dendroclimatological and palaeoecological approaches. …”
