Forests as safety nets for mitigating the impacts of HIV/AIDS in southern Africa

BACKGROUND

70% of the people infected with HIV/AIDS are in Southern Africa, and the disease is perpetrating the already existing poverty in the continent. The impacts of the disease have led to livelihood change, as more funds in households are channeled to health care.

Distribution and genetic diversity of five invasive pests of Eucalyptus in sub-Saharan Africa

BACKGROUND

Plantation forestry in Sub- Saharan Africa has been characterized by an introduction of several Eucalyptus species because of their socio- economic benefits. However, these Eucalyptus trees have been affected by non- native foliage feeding insect pests, which have been accidentally introduced, resulting in stunted growth and in some cases mortality. The rate of introduction of non-native eucalypt-feeding insects globally has increased nearly five-fold between the 1980s and 2010s.

Research on Indigenous Knowledge and its Application: A Case of wild food plants of Zimbabwe

BACKGROUND

There has been so much emphasis on the documentation of Indigenous Knowledge due to the fear that it is getting lost. However, little attention has been given to the application of this knowledge and how it should benefit indigenous communities.

Livelihoods diversification and gender in Malawi

BACKGROUND

More than 50% of the population of Malawi lives in rural areas, in extreme poverty. Women and men have significantly different roles in the making of livelihoods.

A tree-based approach to biomass estimation from remote sensing data in a tropical agricultural landscape

Introduction

Due to increasing agricultural landcover throughout the world, it is critical to develop methods that estimate above ground biomass and carbon in order to accurately monitor terrestrial carbon stocks and predicting carbo dynamics. This paper claims that while active remote sensing data may be a means to achieve these estimates, the plot-based methods may not be suitable for these agricultural areas. Thus, the authors seek an alternative.
