Soil Management And Smallholder Development In The Pacific Islands

The Pacific is the last major world region to be discovered by humans. Although small in total land area, its numerous islands and archipelagoes with their startlingly diverse habitats and biotas, extend across a third of the globe. This revised edition of a popular text explores the diverse landforms, climates, and ecosystems of the Pacific island region. Multiple chapters, written by leading specialists, cover the environment, history, culture, population, and economy. The work includes new or completely revised chapters on gender, music, logging, development, education, urbanization, health, ocean resources, and tourism. Throughout two key issues are addressed: the exceptional environmental challenges and the demographic/economic/political challenges facing the region. Although modern technology and media and waves of continental tourists are fast eroding island cultures, the continuing resilience of Pacific island populations is apparent. This is the only contemporary text on the Pacific Islands that covers both environment and sociocultural issues and will thus be indispensable for any serious student of the region. Unlike other reviews, it treats the entirety of Oceania (with the exception of Australia) and is well illustrated with numerous photos and maps, including a regional atlas.

Large areas of the warm, humid tropics in Southeast Asia, the Pacific, Latin America, the Caribbean, and Africa are hilly or mountainous. Jackson and Scherr (1995) estimate that these tropical hillside areas are inhabited by 500 million people, or one-tenth of the current world population, many of whom practice subsistence agriculture. The region most affected is Asia which has the lowest area of arable land per capita. Aside from limited areas of irrigated terraces, most of the sloping land, which constitutes 60% to 90% of the land resources in many Southeast Asian countries, has been by-passed in the economic development of the region (Maglinao and Hashim, 1993). Poverty in these areas is often high, in contrast to the relative wealth of irri gated rice farms in lowland areas that benefited from the green revolution. Rapid population growth in some countries is also exacerbating the problems of hillside areas. Increasingly, people are migrating from high-potential lowland areas where land is scarce to more remote hillside areas. Such migra tion, together with inherent high population growth, is forcing a transforma tion in land use from subsistence to permanent agriculture on fragile slopes, and is creating a new suite of social, economic, and environmental problems (Garrity, 1993; Maglinao and Hashim, 1993).

The Australasia-Pacific Region supports approximately 50% of the world's population. The last half-century has witnessed a rapid increase in the regional population, agricultural productivity, industrial activities and trade within the region. Both the demand for increased food production and the desire to improve the economic conditions have affected regional environmental quality. This volume presents an overview of the fate of contaminants in the soil environment; current soil management factors used to control contaminant impacts, issues related to sludge and effluent disposals in the soil environment; legal, health and social impacts of contaminated land, remediation approaches and strategies to manage contaminated land, some of the problems associated with environmental degradation in the Australasia-Pacific Region and steps that we need to take to safeguard our environment.
