Degraded lands—lands that have lost some degree of their natural productivity through human activity—account for over 20 percent of forest and agricultural lands in Latin America and the Caribbean. Some 300 million hectares of the region’s forests are considered degraded, and about 350 million hectares are now classified as deforested. The agriculture and forestry sectors are growing and exerting great pressure on natural areas. With the region expected to play an increasingly important role in global food security, this pressure will continue to ratchet up.
Swidden agriculture in tropical Asia is a diverse practice, making it difficult to draw general conclusions on trends of the development of swidden fallow secondary forests (SFSF). There is, however, sufficient evidence to recognise trends of a gradual intensification often through the incorporation of extensive tree crop production in SFSF, or a direct conversion to intensive tree cash cropping. Factors contributing to the changes include emerging markets for cash crops or timber and pulp wood production, government policies and development projects, fire, and population pressures.
Planted oil palm areas increased 20-fold and crude palm oil (CPO) production had a 12% average annual increase from 1967-1997. This conferred important economic benefits but threatened Indonesia's natural forest cover. Large-scale plantations displaced local communities and social conflict resulted. Early in the economic crisis, it was expected the boom would continue, and be propelled by currency depreciation and lifting of foreign investment constraints. However, there was a slowdown in area expansion and CPO production.
This paper examines the conversion of Indonesia’s natural forests to timber and tree crop plantations, notably oil palm. The principal aims are to understand the impact of this process on natural forest and on forest-dwelling people, and to establish whether past and present policies governing this process are meeting their objectives.
Land use changes in East Africa have transformed land cover to farmlands, grazing lands, human settlements and urban centers at the expense of natural vegetation. These changes are associated with deforestation, biodiversity loss and land degradation. A synthesis of results of long term research by an interdisciplinary team reveals the linkages between land use change, biodiversity loss and land degradation. The results indicate that as native vegetation is lost, indigenous plant and animal biodiversity and plant cover are lost.
Rapid land transformation driven by large scale investments is one of the big trends defining this century. In a virtual briefing for the Global Donor Platform members CIAT agriculture expert Deborah Bossio dismisses the cry for more investments often heard in development circles. From her perspective a lack of investments is not the problem. The more pressing question is whether these large scale investments could be sustainable and socially inclusive. How are they going to play out in the end?
Loggers, miners and rural communities all exploit forests in unsustainable ways in search of profits and means of subsistence. They are the primary actors in forest decline and their immediate motivations are the direct causes of deforestation and degradation. However, these motivations are determined, through complex causation chains, by deeper and much more fundamental forces: the underlying causes of deforestation. Effective action against forest decline requires an understanding of these underlying causes and their distant impacts on forests.
The methods used to value tropical forests have the potential to influence how policy makers and others perceive forest landsforestlands. A small number of valuation studies achieve real impact. These are generally succinct accounts supporting a specific perception. However, such reports risk being used to justify inappropriate actions. The end users of such results are rarely those who produced them and misunderstanding of key details is a concern. One defence is to ensure that the ultimate users appreciate shortcomings and common pitfalls.
