Tropical peatlands are found mostly in South East Asia, but also in Africa and in Central and South America. They and peat-swamp forests store large amounts of carbon and their destruction, particularly through the development of plantations for oil palm and other forms of agriculture, releases large quantities of greenhouse gases which contribute to climate change. They are also complex and vulnerable ecosystems, home to great biodiversity and a number of endangered species such as the orang utan.The aim of this book is to introduce this little known but important and vulnerable ecosystem in a way that explains its long standing interaction with the global carbon cycle and how it is being destroyed by deforestation and inappropriate development. The authors describe the origin and formation of peat in the tropics, its current location, extent and amount of carbon stored in it, its biodiversity and natural resource functions and key ecological functions and processes. Appropriate hydrology is the key to the development and maintenance of peatlands and the unique aspects of tropical peatland water supply and management are also explored. In the same vein the nutrient dynamics and budgets of this ecosystem are explained in order to show how complex habitats can be maintained mainly by rainwater containing very low concentrations of essential chemical elements. Past and present impacts on tropical peatlands in SE Asia are discussed and the need for restoration and wise use highlighted. Finally, projections are made about the future of this ecosystem as a result of continuing human impacts and climate change.

Set in West Kalimantan, Indonesian Borneo, this study explores the shifting relationships between border communities and the state along the political border with East Malaysia. The book rests on the premise that remote border regions offer an exciting study arena that can tell us important things about how marginal citizens relate to their nation-state. The basic assumption is that central state authority in the Indonesian borderlands has never been absolute, but waxes and wanes, and state rules and laws are always up for local interpretation and negotiation. In its role as key symbol of state sovereignty, the borderland has become a place were central state authorities are often most eager to govern and exercise power. But as illustrated, the borderland is also a place were state authority is most likely to be challenged, questioned and manipulated as border communities often have multiple loyalties that transcend state borders and contradict imaginations of the state as guardians of national sovereignty and citizenship.

This groundbreaking book describes the emerging field of theoretical immunology, in particular the use of mathematical models to describe the spread of infectious diseases within patients. It reveals fascinating insights into the dynamics of viral and other infections, and the interactions between infectious agents and immune responses. Structured around the examples of HIV/AIDS and hepatitis B, Nowak and May show how mathematical models can help researchers to understand the detailed dynamics of infection and the effects of antiviral therapy. Models are developed to describe the dynamics of drug resistance, immune responses, viral evolution and mutation, and to optimise the design of therapy and vaccines.

Breadfruit has been cultivated by people for thousands of years in highly productive plantings together with numerous other crops. This book was written for commercial and home growers looking to combine modern horticultural techniques with traditional growing methods similar to those successfully employed by Pacific Islanders over many centuries. This groundbreaking guide is being released as the prolific Pacific Island staple breadfruit enjoys a resurgence in planting and growing across Hawai'i and around the tropical world. Noted for its high nutritional value, gluten-free status, and moderate glycemic index, breadfruit (called 'ulu in Hawaiian) can be prepared similarly to a potato or yam but has greater versatility and qualities well suited for main dishes, desserts, baked goods, and even beverages. Breadfruit trees are abundant producers and require far less labor compared with other starchy crops such as taro and sweet potato. The guide presents techniques that can sustain productivity for long periods of time, while regenerating land degraded by erosion, compaction, overgrazing, and loss of organic matter. It covers subjects that include recognizing breadfruit varieties; agroforest planning, planting, and maintenance; selection of suitable accompanying crops; value-added products; and economic evaluation. The guide provides a range of growing scenarios from backyard gardens to large farms in the tropics. Using detailed design examples, species tables, and design descriptions and 95 photos and illustrations, this handbook breaks new ground in showing growers how to plan and implement agroforestry that emphasizes breadfruit production. In so doing, growers can design their production to be resilient to changes in weather and market prices-and build a stronger local food system in the process.
