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.

Garden Plants in Zimbabwe: Their ethnomedicinal uses and reported toxicity

BACKGROUND

In Zimbabwe, there are several plants that have been grown in homes for primary survival and for aesthetic reasons, both exotic and indigenous species. The properties of some of these plants is unknown yet some have been discovered to be poisonous to humans and livestock. Some cases of plant poison have been accidental, hence there is need to protect the public from the toxicity of these plants.

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. Hence this study drew its research on wild food plants of Zimbabwe and attempted to show how indigenous knowledge can be applied in education and community settings.

Assessment of causes that contribute to the occurrence of plantations forests fires in Niassa Province, North of Mozambique

BACKGROUND

The government of Mozambique started to promote exotic forest plantations (pine & eucalyptus) because of low natural forest productivity, population growth and land use pressure. Niassa province was one of the provinces for this plantation program. However, fires in these commercial plantations have brought an enormous risk for companies, yet these companies provide the greatest source of employment for the local people.

A comparative study of medicinal plants used in rural areas of Namibia and Zimbabwe

BACKGROUND

Despite the adoption of Western pharmaceutical drugs in developing countries, traditional medicine produced from wild plants is still the source of primary health care. In some countries up to 90% of the people rely on traditional medicines. Few studies have done a comparative analysis of the herbal medicines in Africa.

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. The country’s economy is based on agriculture which is vulnerable to many shocks, forcing the people to diversify to other economic activities. Male headed and female headed homes respond differently to these shocks. Malawi’s gender policy is aiming at reducing the current gender of disparities.

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.

Multiple successional pathways in human-modified tropical landscapes: new insights from forest succession, forest fragmentation and landscape ecology research

Introduction

With the rise of deforestation, secondary forests and human-modified tropical landscapes (HMTL) have become an important source of ecosystem services yet there is limited knowledge concerning the successional process of these ecosystems. 

Goals & Methods

The goal of this study is to identify the main drivers of successional pathways In HTML and secondary forests at multiple scales. The authors draw on tropical forest succesion, forest fragmentation, and landscape ecology research to achieve this.

Traditional agroforestry practices in Zimbabwe

BACKGROUND

There has been little attention being given to the significance of trees in household economies of Zimbabwe. Most focus has been on crops, livestock, softwood species of trees in commercial plantations and indigenous species that under state management. Extension officers used to encourage people to remove trees from arable land. However, after the country’s independence a Rural Afforestation Program was established resulting in agroforestry engagements.
