Appendix 1: Disturbed forest

Brown, K. Pearce. 1994. The causes of Tropical Deforestation. University of British Colombia. Canada

Document availability: Photocopies of some articles are available in the FRA Library.
This document presents a compilation of studies with various hypotheses as to the causes of deforestation in tropical forests. It presents mechanisms that could provide incentives for the conservation and sustainable management of tropical forests (Data presented in the document are based on FRA 1990).

Participants adopted a set of recommendations (Annex II of the document). This was the final consultation meeting after several meetings in Asia, Africa and Latin America. There was no standard methodology for the conduct and reporting of case studies, so it is difficult to compare results. Conclusion are very general.

Indonesia: There have been several research efforts on the rate and causes of Indonesia's deforestation in recent years, but there is still no consensus in the research community on these causes. The paper reviews these areas of uncertainty and confusion, including the problem of imprecise and conflicting definitions; positive and negative effects of shifting cultivation; tree crop production (rubber, for example); migration, both encouraged and spontaneous; and population density. There is a correlation between population density and deforestation, but it is not clear whether it is causal or incidental. There is typical sequence whereby forests are first cleared by loggers and then occupied by agriculture. Logging takes place on from 77 000 to 120 000 ha annually. Little information exists related to management of logging concessions.

There is a need to study the recuperative capacity of forests following clearing, degradation or other poor management practices. Studies are also needed on the costs and returns of plantations, especially in comparison to agriculture.

Minde, I. et al. 1999. Agricultural Land Expansion and Deforestation in Malawi (draft). Unpublished material

Document availability: FRA Library.

Malawi: Literature on deforestation in Malawi points to a number of causes including high population in relation to available land, poverty, markets, policy failures, drought and the severity of structural adjustment policies. The prevalence of small land holdings leads to cultivation of marginal lands and forest encroachment. When macroeconomic structural adjustments tend to increase the prices of agricultural products the pressure on forest areas increases.

Human population impacts forests through demand for fuelwood and agricultural production, but it is important to know the proportion of material that is collected from the living forest as opposed to dead branches. This can help assess if the activity is driving deforestation or forest degradation.

Document availability: Indiana University (workshop@indiana.edu).
The author presents the problem of measuring social, political and economic variables that affect forest condition. It is difficult to determine the right scale for measurement and analysis. As an alternative, Ostrom presents human choices and the variety of adaptations that individuals may make when populations increase and resources become scarce.

Method and model: International Forestry Resources and Institute (IFRI) research methodology: micro-level, multiyear, multi-country study of demographic and institutional variables and these impacts on human incentives, behaviour and forest ecology.

This document presents population pressure as an important force leading to deforestation, but rarely acting alone to produce the outcome. The qualitative analysis in this study identified important social institutions that can create an environment where population pressure may or may not affect deforestation. Data was provided by the Center for Advanced Studies in the Behaviour Science for Latin America, Africa and Asia.

Method and model: Meta-analysis, a combination of statistical techniques designed to convert disparate statistics to a common system, and development of a coefficient of correlation.

Remarks: Different definitions were used in the countries studied. Each study used a different model or simplification. It was not possible to standardise the estimation procedures used in each study.

The author presents a summary and logic of the various explanations of the causes of deforestation. This review essay is an initial step in a project sponsored by the Beijer Institute of the Royal Swedish Academy of Science that will allow researchers to examine deforestation at multiple levels of analysis. The documents organises the causes of deforestation by (1) demographic factors; (2) agricultural factors (3) macroeconomic factors; (4) industrial factors; (5) forest accessibility; (6) political factors; and (7) land use constrains.

Africa, Asia: Underlying causes of deforestation meetings in Ghana and West Java. Participants mentioned that the structural adjustment programmes of the World Bank had affected the process of forest conservation. Adjustment programmes influenced governments to reduce public expenditures, resulting in the reduction of forest department staff. There are also contradictory strategies between agriculture and forestry. Other major causes were issues of governance, corruption, lack of transparency and participation in decision-making and the rise of militarism.

Asia: The document describes the impact that the poor have on forest degradation and deforestation and the impact that forest degradation/deforestation and various forest policies have on the poor. The draft document will be placed on the web site when it becomes available. The author points out that there is little information about degradation of ecosystems at the local level compared to the information available relating to the global and regional levels.

General: Consumption patterns contribute to the degradation of the earth. Wood fibre consumption and logging have increased during the last year. Changes in consumption habits and improvements in technology and efficiency (alternative products, recycling, etc.) are opportunities that could reduce the impact on ecosystems.

Method and model: No information available.
