Tropical rainforests are disappearing at an alarming rate, causing unprecedented losses in biodiversity and ecosystem services. This book contributes to an improved understanding of the processes that have destabilizing effects on ecological and socio-economic systems of tropical rain forest margins, as well as striving to integrate environmental, technological and socio-economic issues in their solution.

This international symposium featured three interconnected thematic foci of interdisciplinary research. They focussed on the changes in the extent and intensity of agricultural and forest land use in tropical forest margins and their implications for rural development and for conservation of natural resources such as biodiversity, soils and water. The symposium took place in Goettingen. Almost 130 international authors have contributed a short abstract and their adress.

Tropical ecosystems are exceptionally rich in biodiversity, containing most terrestrial biodiversity. However, rapid and extensive forest degradation, which causes modifications of ecosystems and fragmentation of habitats, is leading to an alarming loss of biodiversity (Laurence 1999). Most of the 25 “biodiversity hotspots”, as defined by Myers et al. (2000), are in the tropics and characterized by high levels of endemism and habitat loss. Two of these are partly in Indonesia: the Sundaland (western Indonesia) and the Wallacea (eastern Indonesia). Environmental degradation in Indonesia has been severe during recent decades (Sodhi et al. 2004). From 1990 to 2005, Indonesia lost 21.32 million ha of forest (17.56% of its forest cover); however, the mean rate of deforestation in Indonesia for the period 1990–2000 (1.78 million ha/year) was three times that for 2000–2005 (0.58 million ha/year) (Hansen et al. 2009). Yet despite this decrease in deforestation, forest loss in Indonesia remains high, with more than 500,000 ha lost each year during 2005–2010 (FAO 2010). The main direct causes of these high rates of deforestation are: conversion of forest to agricultural lands, commercial logging, fire and mining (Sodhi et al. 2004).

Fifteen years ago, approximately half the world population was estimated to live in continental and insular South-East Asia (Burma, Thailand, Kampuchea, Vietnam, Laos, Indonesia, Philippines). Then the region had a population growth of four million people every month, and the problem of malnutrition was acute for the rural population. International agricultural development organisations decided that their primary aim would be to double existing levels of agricultural production and, taking account of population growth, to double it again by the end of the century (Whyte 1976). Today, while global issues have greatly affected the parameters of the problem, the situation remains both serious and difficult. Despite impressive efforts in education and health, Indonesia for example, where population (179 millions) growth eased off only slightly between 1980 and 1990 (from 2. 3 percent to 1. 9 percent), is having to cope with increasing difficulties in managing natural resources and particularly its evanescent forest assets which, until 1986, were the second largest source of national revenue. Indonesia has the second largest surface area of tropical rain forests in the world (after Brazil) and thus all the problems linked with management and disappearance of those forests. The latest estimate gives a figure of 109 million hectares of forest in 1990, of which 40. 8 million hectares are production forests (Anon. -F AO 1990).

Since the collapse of Soeharto’s New Order regime in May 1998, Indonesia’s national, provincial, and district governments have engaged in an intense struggle over how authority and the power embedded in it, should be shared. How this ongoing struggle over authority in the forestry sector will ultimately play out is of considerable significance due to the important role that Indonesia’s forests play in supporting rural livelihoods, generating economic revenues, and providing environmental services. This book examines the process of forestry sector decentralization that has occurred in post-Soeharto Indonesia, and assesses the implications of more recent efforts by the national government to recentralize administrative authority over forest resources. It aims to describe the dynamics of decentralization in the forestry sector, to document major changes that occurred as district governments assumed a greater role in administering forest resources, and to assess what the ongoing struggle among Indonesia’s national, provincial, and district governments is likely to mean for forest sustainability, economic development at multiple levels, and rural livelihoods. Drawing from primary research conducted by numerous scientists both at CIFOR and its many Indonesian and international partner institutions since 2000, this book sketches the sectoral context for current governmental reforms by tracing forestry development and the changing structure of forest administration from Indonesia’s independence in 1945 to the fall of Soeharto’s New Order regime in 1998. The authors further examine the origins and scope of Indonesia’s decentralization laws in order to describe the legal-regulatory framework within which decentralization has been implemented both at the macro-level and specifically within the forestry sector. This book also analyses the decentralization of Indonesia’s fiscal system and describes the effects of the country’s new fiscal balancing arrangements on revenue flows from the forestry sector, and describes the dynamics of district-level timber regimes following the adoption of Indonesia’s decentralization laws. Finally, this book also examines the real and anticipated effects of decentralization on land tenure and livelihood security for communities living in and around forested areas, and summarizes major findings and options for possible interventions to strengthen the forestry reform efforts currently underway in Indonesia.
