Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management options, it is important to understand the vegetation dynamics and the major drivers governing the observed conditions. This study uses data from 29 sentinel landscapes (4640 plots) across the southern Africa. We used T-Square distance method to sample trees.

Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

Achieving cooperation in natural resource management is always
a challenge when incentives exist for an individual to maximise her short term
benefits at the cost of a group. We study a public good social dilemma in water
infrastructure provision on land reform farms in Namibia. In the context of the
Namibian land reform, arbitrarily mixed groups of livestock farmers have to share
the operation and maintenance of water infrastructure. Typically, water is mainly
used for livestock production, and livestock numbers are subject to high fluctuations
