    This chapter spells out the theoretical framework for the discussion and case studies of the book. First, it provides precise definitions of technological change and classify technological change into different types based on their factor intensities. The discussion starts off with a single farm household. Two key concepts for understanding how that household will respond to technological changes are economic incentives and constraints. The former relates to how new technologies influence the economic return of different activities.

    Bolivia, Brazil

    This paper looks at the impact of the introduction of new soybean technologies on the clearing of natural vegetation (forest and savanna) in southern Brazil, the Brazilian Cerrado, and Santa Cruz, Bolivia. The paper looks at how technological change interacted with other government policies and examines general equilibrium effects on product and labor markets as well as the direct on-farm effects. In southern Brazil new technologies made large-scale mechanized soybean production more profitable.

    This conference proceedings contains 26 papers based on the activities of partner institutions that the Center for International Forestry Research (CIFOR) has facilitated. There are 4 sections: (i) evaluation of forest harvesting and fire impacts on forest ecosystems; (ii) development of methods to rehabilitate logged-over forests and degraded forest lands; (iii) development of silvicultural techniques on degraded forest lands; and (iv) network of the rehabilitation of degraded forest ecosystems.

    This final chapter of the book offers a set of policy recommendations. It presents some typical win-win outcomes, including technologies suited for forest poor areas, labour intensive technologies promoting intensification to replace land extensive farming practices, and promoting agricultural systems that provide environmental services similar to those of natural forests.

    Ethiopia, Africa, Eastern Africa

    Land degradation is a great threat for the future and it requires great effort and resources to ameliorate. The major causes of land degradation in Ethiopia are the rapid population increase, severe soil loss, deforestation, low vegetative cover and unbalanced crop and livestock production. Inappropriate land-use systems and land-tenure policies enhance desertification and loss of agrobiodiversity. Utilization of dung and crop residues for fuel and other uses disturbs the sustainability of land resources. The supply of inputs such as fertilizer, farm machinery and credits are very low.

    This introductory chapter sets the scene for the discussion in the edited volume on how new agricultural affects tropical forests. It critically reviews four hypotheses that have been central in the claim that better technologies help protect forests: the Borlaug, the subsistence, the economic development and the land degradation-deforestation hypotheses. Each of them appears to be valid only under certain restrictive conditions. The chapter then gives the aims and scope of the book, the key conclusions, as well as a summary of each of the chapters.

    What policy lessons derive from the half-century of banana expansion in the coastal region? For that whole period bananas had a catalytic role in promoting coastal deforestation. At first, this was mostly through direct banana frontier expansion. Later the gradual settlement effects proved key. Modest credit subsidies, the large-scale construction and improvement of roads and ports, and a devalued exchange rate were probably the most important policies that contributed to the expansion of banana production, though they varied in importance during the different periods.

    Do improvements in agricultural technology protect or endanger tropical forests? This book examines this controversial issue. It includes both theoretical frameworks for analysing the issue as well as case studies covering a wide range of geographical regions, technologies, market conditions and types of agricultural procedures. The authors identify technologies, contexts and policies that are likely to be beneficial to both farmers and forests.

    This chapter summarises the key insights from the case studies included in the book. First, it discusses the technology-deforestation link in six different types of cases: developed countries, commodity booms, shifting cultivation, permanent upland (rainfed) agriculture, irrigated (lowland) agriculture, and cattle production. Next, it returns to the hypotheses presented in the book, and discusses the key conditioning factors in the technology-deforestation link. A number of factors determine the outcome.

    In this paper, we present an intensification model based on the intensity of exploitation and use of forests and forest lands as a relevant framework for analysing the appearance, dynamics, and evolution of different types of secondary forests. The systematic driving forces responsible for the disturbances and subsequent secondary forest re growth tend to change and evolve along this continuum.
