Evolution of Environmental Information Systems in Africa

چکیده
Man’s largely uncontrolled use and exploitation of the natural environment and the ever increasing needs of an – arguably overpopulated world have lead to a situation in which only scientific assessment, planning and management can provide some measure of sustainability of the use of natural resources. Especially in the developing world with its limited access to technology, funds and expertise, excessive exploitation of natural resources has caused severe environmental degradation and there are communities which appear to be entirely dependent on an exploitative use of natural resources for their survival. Decision-makers and planners require reliable and current environmental information, to arrive at effective, realistic and sustainable management plans. Environmental Information Systems (EIS) provide a technology by which such environmental information can be combined, structured, managed and made available to planners and decision makers. This technology is an expansion of Geographic Information Systems (GIS). The paper will examine EIS in the context of environmental management and outline the role GIS plays in this discipline. The paper will report on the evolution of EIS in Africa in the context of Nolan’s four-stage model. Problems such as technical constraints, institutional barriers and limited human resources that have characterised the implementation of EIS will be noted. The paper will outline some benefits of introducing EIS and conclude by looking at the future of EIS as well as suggesting some possible ways of overcoming some of the inhibiting factors. * Corresponding author.

Influence of environmental factors on the sap flux density of mango trees under rain-fed cropping systems in West Africa
Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...
متن کاملNon-physician Clinicians – A Gain for Physicians’ Working in Sub-Saharan Africa; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”
The changing demands on the health sectors in low- and middle-income countries especially sub-Saharan African countries continue to challenge efforts to address critical shortages of the health workforce. Addressing these challenges have led to the evolution of “non-physician clinicians” (NPCs), that assume some physician roles and thus mitigate the continuing shortage of doctors in these count...

متن کاملEvaluating the Growth and Evolution of Facility Management in Innovating Integrating and Aligning Business Strategies to Achieve a Competitive Advantage
The South African Facilities Management (FM) industry has seen increased operational strategy complexity from single-site contractors providing basic janitorial services to highly integrated and bundled FM service providers. Despite these major changes, very little research has been conducted on evaluating the effectiveness of FM in innovating, integrating and aligning business strategies to a...
متن کاملClimate-Human interaction over the Iranian Plateau during the Upper Pleistocene-Holocene: A review
During the past two decades an array of studies have shed light on potential links between the evolution of Hominids as well as Human dispersal out of Africa and episodes of abrupt climate change. Although archaeological evidences suggest that anatomically modified humans appeared in Africa between 200 and 150 ky ago, the timing of the early humans migration out of Africa remained unclear.
