The aim of this book is to demonstrate how environmental factors have caused an evolution in the landscape of national security since the end of the Cold War. Through relevant case studies, the scope of the problem on the national security landscape due to environmental stressors is illuminated, examined, and synthesized with climate-related data. Human variables such as governance, GDP, and vulnerability are taken into account, and are compared against environmental factors to more accurately determine the causative agents of regional conflicts which threaten national security. These case studies comprise the majority of the text, and they show how individual conflicts are uniquely influenced by environmental stress with variations from situation to situation. This book will be of interest to government and military professionals, and may serve as a resource for college courses in the areas of military geography, international affairs, and sustainability studies.

Nowadays it is hard to find areas of human activity and development that have not profited from or contributed to remote sensing. Natural, physical and social activities find in remote sensing a common ground for interaction and development. This book intends to show the reader how remote sensing impacts other areas of science, technology, and human activity, by displaying a selected number of high quality contributions dealing with different remote sensing applications.

As Africa urbanises and the focus of poverty shifts to urban centres, there is an imperative to address poverty in African cities. This is particularly the case in smaller cities, which are often the most rapidly urbanising, but the least able to cope with this growth. This book argues that an examination of the food system and food security provides a valuable lens to interrogate urban poverty. Chapters examine the linkages between poverty, urban food systems and local governance with a focus on case studies from three smaller or secondary cities in Africa: Kisumu (Kenya), Kitwe (Zambia) and Epworth (Zimbabwe). The book makes a wider contribution to debates on urban studies and urban governance in Africa through analysis of the causes and consequences of the paucity of urban-scale data for decision makers, and by presenting potential methodological innovations to address this paucity. As the global development agenda is increasingly focusing on urban issues, most notably the urban goal of the new Sustainable Development Goals and the New Urban Agenda, the work is timely.

The main goal of this book is to put urbanization and its challenges squarely on Africa’s development agenda. Planned urbanization can improve living conditions for the majority, help in the expansion of the middle class, and create conditions for economic transformation. However, many African cities have developed haphazardly, resulting in the decline of public services, in slum proliferation, and increases in poverty. African cities thrive on activities characterized by easy entry and low productivity, generally referred to as the "informal sector". Indeed, today some urban dwellers are poorer than their cousins in the countryside. In spite of reform attempts, many governments have not been able to create an enabling environment, with adequate infrastructure and institutions to sustain markets for easy exchange and production. This study argues that with careful policies and planning, the situation can be changed. If the recent natural resource-led economic boom that we have seen in many African countries is used for structural reforms and urban renewal, African cities could become centers of economic opportunity. The challenge for African policymakers is to ensure that urban development is orderly and that the process is inclusive and emphasizes the protection of the environment, hence green growth.
