Mangrove stands in the Western and Central African countries especially that of Cameroon are declining due to diverse drivers. Actually, Rhizophora racemosa stands in the Cameroon Estuary have been degraded through over-exploitation for fish smoking, pole-wood extraction and fuel wood harvesting by local people in the midst where there is no specific law protecting this ecosystem. Recently, community-based mangrove... Read more.

Anthropogenic activities have the potential to thwart efforts towards enhancing the full carbon (C) sink potential of savannas in the context of mitigating the effects of global warming. The understanding of the induced effects of human pressures on the carbon budget of forest˗savanna ecosystems is therefore a valuable tool to better evaluate and predict the current and future effects of human activities on the...

Increasing effects of climate change has led to an urgent need for reliable estimates of the soil carbon pool (SOC) which is one of the carbon sinks in the world. This is especially true in Africa where there is lack of basic data. This study conducted in the southern part of Mount Cameroon National Park (MCNP) seeks to determine SOC patterns and estimate CO2 equivalence from SOC pool following land-use changes. Nine...

This study sought to establish an inventory of plant species established at three gravel borrow pits around Gaborone, Botswana. At each, plant data were collected from randomly selected 10 x 10 m quadrats within and up to 30 m away from the borrow pits. Species of Acacia were the most numerous in the pits, while more non-woody than woody species were established within the pits. Most woody species within the pits were... Read more.

This paper reviews several studies on the impacts of climate change on developing countries in Africa, one of the most vulnerable continents due to lack of financial, technical and institutional capacity to cope with the impacts of climate change. Due to various anthropogenic activities, greenhouse gases are increasing in the atmosphere at an alarming rate which leads to extreme temperature and flooding, loss of soil... Read more.
