  • Who Counts Most? Assessing Human Well-Being in Sustainable Forest Management
    FA-CIFOR-Tool8Cover 6/15/99 8:25 AM Page 1 8 Who Counts Most? Assessing Human Well-Being The Grab Bag: Supplementary Methods for Assessing Human Well-Being Human Assessing for Methods Bag: Supplementary Grab The in Sustainable Forest Management Who Counts Most? Assessing Human Well-Being in Sustainable Forest Management presents a tool, ‘the Who Counts Matrix’, for differentiating ‘forest actors’, or people whose well-being and forest management are intimately intertwined, from other stakeholders. The authors argue for focusing formal attention on forest actors in efforts to develop sustainable forest management. They suggest seven dimensions by which forest actors can be differentiated from other stakeholders, and a simple scoring technique for use by formal managers in deter- mining whose well-being must form an integral part of sustainable forest management in a given locale. Building on the work carried out by the Center for International Forestry Research (CIFOR) on criteria and indi- cators, they present three illustrative sets of stakeholders, from Indonesia, Côte d’Ivoire and the United States, and Who Counts Matrices from seven trials, in an appendix. 8The Criteria & Indicators Toolbox Series FA-CIFOR-Toolbox8-11.05 6/15/99 7:51 AM Page A2 ©1999 by Center for International Forestry Research Designed and Printed by AFTERHOURS +62 21 8306819 Photography Gorilla g. beringei by Tim Geer (WWF) Waterfall, Indonesia by Susan Archibald Kenyah hunter, Tanah Merah, Indonesia by Alain Compost Dendrobium sp.

  • Introduction -- History and Conceptual Framework
    INTRODUCTION History and Conceptual Framework Carol J. Pierce Colfer and Yvonne Byron, with Ravi Prabhu and Eva Wollenberg Confusion and dismay are rampant among those concerned about human and environmental issues in the tropics, and with good reason. Forests are being degraded at apparently ever-increasing rates, and human welfare in for- ested areas is remaining at a constant level at best, more often deteriorating. Many people—researchers, environmentalists, and policymakers of various hues—are trying to address these problems. This book represents the evolu- tion of one cooperative effort to understand and develop mechanisms for dealing with these interrelated problems, and the authors propose some sug- gestions for improving our future efforts. In our research, we have asked ourselves one fundamental question: how can we create conditions that allow local people who live in and around for- ests to maintain the valued aspects of their own way of life and to prosper while still protecting those forests on which they, and perhaps the rest of us, depend? To answer that question, we needed first to identify the conditions that contribute to sustainable forest management (SFM) in general and to the well-being of forest-dwelling people in particular. Satisfied that we had a good grasp of the most important conditions (see later), we set out to exam- ine their relationship to sustainability. This examination is the central theme of this book. Central issues of concern include the identification and roles of relevant stakeholders (including gender and diversity, discussed in Section 1, and the relevance of a “conservation ethic,” discussed in Section 2), security of intergenerational access to forest resources (Section 3), and rights and responsibilities to manage forests cooperatively and equitably (Section 4).

The availability of favourable conditions for carbonate sedimentation around Borneo was related to a combination of factors, including tectonic setting, the formation of large basinal areas, dierential subsidence providing shallow marine areas, a tropical climate and a range of local factors, such as currents or limited clastic input. A detailed sedimentological and diagenetic study was undertaken of middle Eocene to Plio±Pleistocene carbonates which developed in the north Kutai Basin and the Mangkalihat Peninsula, northeast Kalimantan. Carbonate sedimentation in this area occurred in a range of depositional environments, from mixed carbonate clastic shelves, localised and transient shoals or reefs, a variety of platform top settings to deep water redeposited carbonates. An understanding of carbonate depositional environments, spatial facies relationships, and diagenesis is essential in order to develop models for these carbonates which can be used as predictive tools in the subsurface.

  • Local Forest Management in Indonesia: a Contradiction Between National Forest Policy and Reality
    International Review for Environmental Strategies Vol.1, No.1, pp. 175 – 191, 2000 ©Institute for Global Environmental Strategies All rights reserved. Article Local Forest Management in Indonesia: A Contradiction Between National Forest Policy and Reality Martinus Nanang*a and Makoto Inoueb Received October 31, 1999, accepted April 21, 2000 Local Forest Management (LFM) is an important alternative strategy for conserving the for- est, and for allowing both forest dwellers and larger stakeholders to benefit from the forest. However, in many cases national policies do not favor LFM. This article critically reviews Indonesia’s national forest policies and indicates how they contradict the principles and prac- tices of Local Forest Management. For this purpose, an excerpt from a research report on forest management by a local community in East Kalimantan is provided. This includes natural re- source tenure, land classification and utilization, forest product utilization and the negative impact of industrial tree plantations. A review of LFM policies, land and forestry laws and the prospect of forestry reform in the future is provided after a discussion of the local situation. This article argues that local people are able to manage the forest in a sustainable way based on their traditions. Accordingly, it is important to have a fair evaluation of customary laws, to avoid uniform application of forest development and to recognize the reality of land use and the socioeconomic conditions as criteria for forest land classification. The involvement of local people and NGOs should be clearly defined in the form of decrees or laws. Keywords: Local forest management, Forest policy, Forest utilization, Natural resource tenure, Participation.

    Berita Sedimentologi [Pick the date] Tracing the Provenance of the Devonian Limestone of Telen River, East Kalimantan Herman Darman PT. Eksindo Pratama, Jakarta, Indonesia (currently with Petronas Carigali, Kuala Lumpur, Malaysia) INTRODUCTION H. Witkamp found an outcrop with Devonian Limestone in East Kalimantan in 1925. In 1989, an expedition run by Institute of Technology Bandung (ITB) reinvestigated the outcrop and concluded that the Devonian Limestones in Telen River were boulders within a Permian formation (Arief et al., 1989). This paper gives a wider overview on the distribution of Devonian rocks in Asia Pacific region and discusses their possible origin. Based on the distribution map of Devonian rocks in the region, the Devonian limestone in Borneo is very isolated. The closest Devonian limestones are about more than 2000 km away (Figure 1). Probably the Devonian limestone in Telen River has been separated away from its origin by significant tectonic movement. There are several theories and models related to the formation history of this area, which makes it very complex. To understand the origin of these limestones, the geology needs to be restored to their time and place of deposition of the Devonian limestone. Figure 1: Distribution map of Devonian Rocks in Asia-Pacific region, in the vicinity of Telen River, East Borneo (based on several sources e.g. IHS, Tellus etc.) Number 47 – May 2021 Page 57 of 82 Berita Sedimentologi [Pick the date] DEVONIAN ROCK DISTRIBUTION IN ASIA penetrated a metamorphic basement which is PACIFIC interpreted as Devonian in age.
