The problem of water scarcity and clean water in sub-Saharan Africa is a growing concern. This study aims to quantify the water quality on a temporal scale in the Doorndraai dam site in sub-Saharan Africa to design possible management options. Here, an integrated approach using both in-situ measurements of water quality parameters and remote...

The aim of this two-volume book series is to highlight some of the most pervasive sustainability challenges that Sub-Saharan Africa faces. The two volumes contain 20 chapters that illustrate very diverse sustainability challenges throughout the continent, adopting interdisciplinary and problem-oriented research approaches, and methods from the...

Droughts and floods are some of the major climatic hazards in the semi-arid areas of Sub-Saharan Africa (SSA). Climate change affects the periodicity and severity of such hazards, and eventually the well-being of many rural communities in the region, including semi-arid Ghana. Enhancing the resilience of local communities to droughts and floods...

Although it is widely acknowledged that forests provide critical ecosystem services for human survival and well-being, in the Asia-Pacific region forests are being converted to other land uses and degraded at alarming rates. One underlying factor for this destruction of forests is market failure. Forests are cleared for other land uses or degraded...

Operational monitoring of vegetation and its response to climate change involves the use of vegetation indices (VIs) in relation to relevant climatic data. This study analyses the temporal variations of vegetation indices in response to climatic data (temperature and precipitation) to better understand the phenological changes in the Wa -West and...

To classify Very-High-Resolution (VHR) imagery, Geographic Object Based Image Analysis (GEOBIA) is the most popular method used to produce high quality Land-Use/Land-Cover maps. A crucial step in GEOBIA is the appropriate parametrization of the segmentation algorithm prior to the classification. However, little effort has been made to automatically...

Recognising the importance of markets to sustainable forest management, this document provides guidance to timber buyers on the steps that they can take to responsibly purchase Papua New Guinean export timber. Log exports have been a major foreign exchange earner for PNG, but weak enforcement of forest laws means that the forest estate is mostly...

This report aims to contribute to the management of PNG’s forests as a renewable natural asset for the collective benefit of all Papua New Guineans. It argues that to achieve these ends, illegalities in the forest sector need serious attention. The report aims to (i) provide a review of the illegal logging issue in PNG, (ii) identify the potential...
