Agricultural Education, Science and Modern Technology's Role in Solving the Problems of Global Food Resources in the 21st Century

Reports & Research
Policy Papers & Briefs
Diciembre, 1998

The growth of agriculture output over the past 200 years has been phenomenal. When Malthus wrote in 1798, he perceived limits on agricultural production as serious and imminent. Since then world population has increased by six-fold and global agricultural production has more than kept pace. Falling real grain prices for most of the 20th Century are cited as evidence. The sources of the increase in food production, however, have been quite different and have come in distinct waves. For most of the 19th century, increased output came from expanded land area in production.

A review of dipterocarps: taxonomy, ecology and silviculture

Journal Articles & Books
Diciembre, 1998
Asia

Dipterocarps are one of the best known and commercially important groups of tropical trees. They preside over some of the most magnificent forest formations in the world. Exploitation of dipterocarp-dominated tropical rain forests has expanded rapidly in the past 20 years. Efforts to develop and implement sustainable management practices are being intensified and there is a pressing need for high quality information on which to base management decisions and reorient research.

Economic models of tropical deforestation: a review

Journal Articles & Books
Diciembre, 1998

As international concern over tropical deforestation has grown over the last ten years, researchers have sought to understand the causes of deforestation and possible solutions using quantitative economic models. This book reviews the results and methodology of over 150 of these models and synthesizes the main lessons that can be learned from them. Higher agricultural prices, lower wages, less off-farm employment, and more roads generally lead to more deforestation. Major doubts remain on the impact of technological change, agricultural input prices, household incomes, and tenure security.

Ganadería y deforestación en América Latina Tropical: Qué podemos hacer?

Reports & Research
Diciembre, 1998
América central
América del Sur

Short-term trends show that livestock production is becoming an increasingly important factor in regional development, possibly because of the combined effect of increasing the forages on offer and planting crops better adapted to the environmental and economic conditions of marginal areas and the decreasing interest of the State in expanding the agricultural frontier. Overall planning of land use should be improved, but to do so, a more detailed characterization and monitoring of deforestation are essential.

Incomes from the forest: methods for the development and conservation of forest products for local communities

Journal Articles & Books
Diciembre, 1998

In the last two decades, there has been increasing interest in the potential of small-scale non-timber forest product collection and other low-impact uses of the forest for achieving forest conservation. Experience suggests however that such uses do not guarantee conservation and economic outcomes. This book documents and compares methods to assess options for forest-based livelihoods and their outcomes.

Rational exploitations: economic criteria & indicators for sustainable management of tropical forests

Journal Articles & Books
Diciembre, 1998

If one is of the mindset that the world is fundamentally chaotic and irrational, then the discpline of economics probably has little to offer. But if one accepts the notion that there is some method to the apparent madness of individuals, governments and organizations, then economic inquiry does have no some contributions to make. In this excercise, we argue that economic criteria and indicators of sustainable forest management should reflect the dimensions of efficiency, equity and sustainability, and need to look beyond the forest stand to institutional and policy issues.
