Earth building is a sustainable, environmentally friendly and economical method of construction that has been used worldwide for many centuries. For the past three decades, earth has seen a revival as a building material for a modern construction method due to its benefits in terms of low carbon...

Decision support tools based on multi-attribute analysis involve the use of different types of variables. These variables are aimed at providing a framework that allows preferences to be quantified. This is particularly useful in the field of sustainability, where variables with different units...

How we know, is at least as important as what we know: Before educationalists can begin to teach sustainability, we need to explore our own views of the world and how these are formed. The paper explores the ontological assumptions that underpin, usually implicitly, the pedagogical relationship...

Groundwater is increasingly relied on as a source of potable water in developing countries, but factors such as population growth, development, and climate variability, pose potential challenges for ongoing sustainable supply. The effect of these factors on the groundwater system was considered...

Disaster plans almost always do not benefit from the knowledge and values of disadvantaged people who are frequently underrepresented in disaster planning processes. Consequently, the plans are inconsistent with the conditions, concerns, and capabilities of disadvantaged people. We present an...

In the contemporary world, a revolution in digital technologies has changed our way of life—for better. The role of women is expanding in socio-economic, political and physical spaces; hence their empowerment will contribute toward resilience and capacity building that contributes to...

A study of sustainability needs to consider the role of all forms of capital—natural, biological, social, technological, financial, cultural—and the complex ways in which they interact. All forms of capital derive their value, utility and application from human mental awareness, creativity...

Agricultural biodiversity has hitherto been valued almost exclusively as a source of traits that can be used in scientific breeding programs to improve the productivity of crop varieties and livestock breeds. We argue that it can make a far greater contribution to increased productivity. In...

Severe watershed degradation continues to occur in the tropical regions of southern Africa. This has raised interest to harness and manipulate the potential of the watershed resources for human benefit as the populations grow. Songwe River is one such degrading watershed causing biennial...

A literature review was undertaken to identify methods being used to handle and treat hatchery waste. Hatchery waste can be separated into solid waste and liquid waste by centrifuging or by using screens. Potential methods for treating hatchery waste on site include use of a furnace to heat the...
