In the context of heightened climate variability, thinking about ways to redesign our urban areas with more sustainable infrastructure solutions is becoming more and more important. Green infrastructure (GI) is emerging as an alternative approach to traditional (‘grey’) infrastructure in urban planning and development. Its emergence can be understood in terms of the growing demand for infrastructure and services, increased concerns over natural resource constraints and climate change, and the negative impacts associated with traditional approaches to designing and building cities. It has been proposed that GI can provide the same services as traditional infrastructure at a similar capita...
The aim of this occasional paper is to gain a better understanding of urban agriculture within the green infrastructure network in the City of Johannesburg and to identify the range of ecosystem services that could be delivered when maintaining and investing in these assets. The analysis in this paper adopts a multi-method approach to (1) identify the interlinkages between urban agriculture and social, economic and environmental systems in the City of Johannesburg; (2) validate these critical interlinkages with stakeholder input and ground-level experience of urban agriculture; and (3) visualise these interlinkages through a spatial analysis of food gardens in the City of Johannesburg.
This report presents three hypothetical case studies for how the AIDS epidemic in Africa could evolve over the next 20 years based on policy decisions taken today by African leaders and the rest of the world; and considers the factors likely to drive the future responses of African countries and the international community. The scenarios draw on the age-old tradition of story-telling, rather than using data projections, to explore the wider context of the AIDS epidemic, reflecting the complexity of the subject matter.
As the population, economy and urban built environment in the Gauteng City-Region (GCR) expand, government is increasingly under pressure to provide urban infrastructure to support growth. It is increasingly important that this infrastructure is sustainable, minimising the negative environmental impacts often associated with traditional forms of urban development. Green Infrastructure (GI) is the interconnected set of natural and man-made ecological systems, green spaces and other landscape features that provide services and strategic functions in the same way as traditional infrastructure. In harnessing the benefits of ecosystem services, GI has emerged as a more efficient, cost effective a...
In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.
"Peace Ecology" presents a cutting-edge exploration of an emerging paradigm that links the essence of peace and nonviolence with the tenets of ecology and the principles of environmentalism. Looking at issues including food justice, water sharing, climate change, peace zones, and the free economy, this book considers examples and illustrations from around the world where people, communities, and nations are employing the teachings of ecology as a tool for mitigating conflict and promoting peace. "Peace Ecology" presents an integrative perspective that bears directly upon the most pressing issues of our time, constituting both the ecological realm of peace and the peacemaking potential of eco...
