DOWNLOAD EBOOKAgriculture dominates the rural economy of Papua New Guinea (PNG). More than five million rural dwellers (80% of the population) earn a living from subsistence agriculture and selling crops in domestic and international markets. Many aspects of agriculture in PNG are described in this data-rich book. Topics include agricultural environments in which crops are grown; production of food crops, cash crops and animals; land use; soils; demography; migration; the macro-economic environment; gender issues; governance of agricultural institutions; and transport. The history of agriculture over the 50 000 years that PNG has been occupied by humans is summarised. Much of the information presented is not readily available within PNG. The book contains results of many new analyses, including a food budget for the entire nation. The text is supported by 165 tables and 215 maps and figures.

DOWNLOAD EBOOKWide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

DOWNLOAD EBOOKA Place Against Time is an ethnographically focused environmental study of Montane, New Guinea, where people were among the world's first to cultivate crops some ten millennia ago, and where today an enduring agricultural condition continues. It arranges its account of climate, vegetation topography and geology according to their relationship with the soils of the region occupied by Wola speakers in the Southern Highlands Province of Papua New Guinea, in the Western Pacific. This book breaks new intellectual ground as an ethno-environmental investigation with a soils perspective, ethno-pedology being a little researched topic to date.
