The intensity of events varied vary across the region, events interacted across the region. The intensity plot showed that events are more concentrated at latitude-12.00 and longitude 35.00. Ripley's k-function revealed that events are clustered up to a distance of 14 km. We tested hypothesis that Higher amounts of dry mass productivity (DMP) and the normalized difference vegetation index (NDVI) result in more fire occurrences and more biomass burning, we also hypothesized that dry woodlands in savannah ecosystems result in more fire occurrences as compared to other land cover types in MaxEnt. Results showed DMP, NDVI and land cover types can be used to model fire occurrences with an ACU of 0,760.It also showed that as DMP and NDVI increased fire occurrence probability also increased. More fires are concentrated (0.79) in crop land with woody vegetation and closed grass land cover types. All the countries in Southern Africa have a high fire risky .

Waste is one of the major environmental factors affecting sustainability. South Africa produces millions of tons of waste per year. The main aim of the study was to identify the nature and quantity the waste and identify most effective ways of disposal.The study was conducted using both the qualitative and quantitative research. The overall number of the industries that were given survey questionnaires and 19 responded and some are on the waiting list. The idea behind interviews was to find out what managers and supervisors of industries think about EIP, looking at the managers’ perceptions and attitudes towards the idea. It was noted that Waste reduction and minimization efforts need to be increased and the problem clearly calls for going a step further by initiating an industrial ecology approach. Was...

It is based on an extensive literature study, taking into account recent major reviews, and considering a wide range of different views from eminent experts worldwideMost research has focused on trying to implement and introduce humanitarian logistics and supply chain management to Humanitarian organizations in trying to make their efforts quicker, efficient and cost effective such researchers include, Clark and Culkin , Thomas, Van Wassenhove, Kleindorfer and Van Wassenhove, Thomas and Mizushima, Tomasini and Van Wassenhove , Qiang and Nagurney , Thompson . Some even further suggest Supply Chain Analytics for Humanitarian Logistics Transformation focuses on the important role of humanitarian logistics, Networks for Africa in support for the implementation of the Millennium Development Goals. Some research has also focused on comparing the l...

Supply interruption will increase the risk of treatment failure and development of ARV resistance, hence there is a need to strengthen the current supply chain and logistics so as to reduce the risk of stock outs and to also strengthen the capacity of the government of Zimbabwe to absorb the high volumes of HIV/ AIDS commodities from the global fund and other donors. The study mainly used primary data collection method including a survey and interview. Secondary data from the literature review, was also complimented by semi-structured interviews with management and personnel in the organizations studied. Solutions and recommendations were then identified in order to attend to the identified deficiencies, problems and challenges. .

Cooperatives have being receiving the support from government, but there is very little success. The study used qualitative research methods, data was gathered from 200 cooperative that were situated in Limpopo and Gauteng province, through focused group interview, one on one interviews and observations. Secondary data was gathered through an extensive literature review. The research recommends that responsi...
