Book Description
This report outlines the development of new methods to assess land resource potential and agricultural pressure in Papua New Guinea. Land resource potential was derived through the classification of environmental data relevant to the growth and management of crops under village conditions. Parameters such as annual rainfall, rainfall seasonality, temperature, light, flooding, slope gradient and soil type were classified according to crop growth constraints. Information on land resource potential pressure is being used to guide and prioritise the research activities of the PNG National Agricultural Research Institute along with the rural development activities of international development donors and all levels of government within the country. While the work is specific to PNG, the methods presented are generic and applicable to most situations depending on data availability.

Book Description
Abstract: Food, water and energy form some of the basic elements of sustainability considerations. This ground-breaking book examines and decodes these elements, exploring how a range of countries make decisions regarding their energy and bio-resource consumption and procurement. The authors consider how these choices impact not only the societies and environments of those countries, but the world in general. 1. Sustainability - Clues for Positive Societal and Ecosystem Change2. Learning From the Past: Why Societies Collapsed or Survived3. Today: Decoding Country Resource Stories4. Fossil Energy Endowments and Externalities5. Forests - the Backbone and Circulatory System for Human Societies6. The Soil and Water Connection to Food: Adapt, Mitigate, or Die7. The Future: Climate Change as a Global Driver Impacting Sustainability8. Where the Past and Future meet: Soils or the Unseen Earth that Nurtures Societies9. The Ultimate Constraint to Human Sustainability: Solar IncomePART 2: Scientific Approach to Decoding SustainabilityPART 3: The Real Country StoriesPART 4. Climate and Soils: Unavoidable Constraints To Solar CapitalPART 5. Societies Adapt To a Quagmire of Resource ChoicesReferencesTo achieve this, the authors review the merits of various sustainability and environmental metrics, and then apply these to 34 countries that are ranked low, medium or high on the human development index. The book assesses their resource capacities and the environmental impacts, both within and outside their country boundaries, from consuming food, water, and energy. The final section uses the lessons derived from the earlier analyses of resource consumption to explore the importance of geography, climates and sustainable management of forests and other natural resources for building resilient societies in the future

Book Description
This topic is central to contemporary concerns for more sustainable agricultural development. This is a well-written and clear book, with excellent data, tables and illustrations, addressing issues of water use, climate change, poverty and small farmers. The authors are highly respected and complement each other's acknowledged international expertise.' Professor Jules Pretty, University of Essex, UK 'This useful guide shows that there is great potential for increasing the productive capacity of smallholder farms in the drylands via a range of water management techniques, from the simple to the more complex. Providing a theoretical grounding and a practical guide, Water and cereals in the drylands will appeal to workers on-location as well as students, researchers and policymakers.' New Agriculturalist Cereals are by far the most important source of food throughout the world, either directly for human consumption or indirectly in the form of animal feed for livestock products consumed as food. With world population set to rise to nine billion by 2050, there is an urgent need to examine ways to increase cereal production. Indeed recently the future of cereal production and consumption has been complicated by rising energy prices and the economics of biofuels, which are competing for the use of cereals. One way to increase cereal production is by the more effective use of marginal dryland areas. This book reviews the potential for increased cereal production in drylands across the world, from the USA, Australia and Southern Europe to Asia and Africa. It describes how improved water conservation, water harvesting and investment options can contribute to this, and suggests policies for the more efficient use of existing natural resources in order to lessen the dependence of agriculture on further irrigation development.

Book Description
Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.

Book Description
Soils play multiple roles in the quality of life throughout the world, not only as the resource for food production, but also as the support for our structures, the environment, the medium for waste disposal, water, and the storage of nutrients. A healthy soil can sustain biological productivity, maintain environmental quality, and promote plant and animal health. Understanding the impact of land management practices on soil properties and processes can provide useful indicators of economic and environmental sustainability. The sixteen chapters of this book orchestrate a multidisciplinary composition of current trends in soil health. Soil Health and Land Use Management provides a broad vision of the fundamental importance of soil health. In addition, the development of feasible management and remediation strategies to preserve and ameliorate the fitness of soils are discussed in this book. Strategies to improve land management and relevant case studies are covered, as well as the importance of characterizing soil properties to develop management and remediation strategies. Moreover, the current management of several environmental scenarios of high concern is presented, while the final chapters propose new methodologies for soil pollution assessment.

Book Description
It took a long time for humans to recognize the existence of a direct link between environmental pollution and health deterioration. In the 1990s, scientists demonstrated the existence of this link through epidemiological studies and new technical materials that can measure accumulation effects of small toxic quantities. Consequently, concerns about human health were accentuated, and the notion of environmental health has emerged. This book covers some practices for managing, controlling, and preventing environmental factors that may affect current and future generations' health. Topics relate to either the natural or the built environment and include air and water pollution, rainwater harvesting, climate change effects, marine pollution, and ecological indicators.

Book Description
This book examines the links between climate change and resource scarcity to violent conflict. Does climate change cause conflicts? This book analyses the economic, political and social conditions under which countries with low levels of freshwater or arable land experience armed conflict. There are strong theoretic arguments linking climate change and scarcity of livelihood resources to conflict. However, empirical accounts are contradictory. Using qualitative comparative analysis (fsQCA), this book compares 22 political, economic and social conditions across 30 countries experiencing scarcity of available freshwater or arable land. The results show that there are three types of resource-scarce countries that experience conflicts: (neo)patrimonial states, oil-rich states that are poorly integrated into the global economy and least developed states. In addition, the results reveal that there are two types of resource scarce countries that remain peaceful: non-agrarian countries with either even development between groups or high integration into the global economy with high levels of adaptive capacities. This explains the contradictory results of previous empirical studies and suggests that resource scarcity might contribute to conflict in least developed countries. This book will be of much interest to students of climate change, critical security, peace and conflict studies, and IR in general.
