Abstract

Twelve eucalyptus hybrid clones (6 grandis-camaldulensis i.e. GC and 3 grandis-urophylla i.e. GU hybrids) and 3 local landraces (E. camaldulensis, E. tereticornis, and E. urophylla) were established in Gede, Sokoke, and Msambweni in the Coast Province of Kenya in 2002, to compare growth, survival, and adaptability in the 3 sites.  By the end of the 1st year, trees in Sokoke were more than 3 times the mean height of those in Gede and Msambweni. However, these growth advantages during the 1st year in Sokoke were not maintained and by year 2 Gede had caught up, although Msambweni still lagged behind. By age 5 there were significant growth differences between clones. Of the tree sites, Msambweni had the lowest tree growth.  GC167, GC14, GC581, and GC584 proved themselves as the better clones, while E. camaldulensis and E. urophylla were the better local land races. Overall, the “local land races” performed poorly in all sites.  Survivals were over 80% in all sites for the best performing clones. However, in Sokoke, 1 clone died (GU7) while another (GU8) had a survival of less than 20%, while EC and ET had survivals less than 35%. GC796 died in Msambweni and had 8% survival at Gede. The poor survivals in Sokoke may have been due to a severe drought in the 3rd year.  The initial outstanding growth performance in Sokoke may have been due to the fact that Sokoke was a ‘virgin’ forest site and presumably more fertile than the other two sites. These results show that recommendations on outstanding clones or new germplasm for planting or sale to farmers are best done at the end of the rotation for a particular intended product or use.

Abstract

Furniture is a major export commodity in Indonesia with a total value of USD 1.96 million in 2007.  Jepara District is one of the key location for wood furniture production with 15,271 furniture related business units employing 176,469 workers.  However, inefficiencies and power imbalances throughout the furniture value chain have resulted in overharvesting and uneven distribution of gains among the industry’s actors.  In contrast to price-setting international furniture retailers, small-scale producers enjoy the least value from their products.  In order to increase added value and competitiveness, small-scale furniture producers have made efforts to upgrade by harnessing their social network and institutions.  This paper describes small-scale furniture producers’ efforts to upgrade by utilising their social network and institutions in Jepara.  Data was collected through in-depth interviews with members of the small-scale furniture producers’ association.  The research provides insight into the nature of social networks and information flow and develops future scenarios to upgrade.  The scenarios will not only benefit the furniture industry in Jepara, but may also be adopted for similar industries throughout Indonesia and the world, and potentially improve many people’s economies and livelihoods.

Abstract

Peat swamp forest is an important pool of terrestrial carbon stock (C-stock). Therefore, research on change of C-stock and its economic value of peat swamp forest conversion to pulpwood industrial plantation forest is important. The objectives of this research are to know the change of C-stock on peat swamp forest conversion to pulpwood industrial plantation forest, and to get the carbon economic value of peat swamp forest and pulpwood industrial plantation forest. The result showed that conversion from logged over and secondary forest causing the decrease of C-stocks of 103.53 and 61.02 t ha-1 year-1, while conversion from degraded forest causing the increase of C-stocks of 22.47 t ha-1 year-1. REDD project on pulpwood industrial plantation forest from degraded land causing the increase of NPV of 20.21% and 51.13% for compensation prices US$ 9 and 12 tCO2-e-1. REDD project with conservation on secondary forest gave lower economic value than pulpwood industrial plantation forest at all compensation prices simulation, and REDD project with preservation logging gave higher economic value than pulpwood industrial plantation forest at compensation price US$ 12 tCO2-e-1. REDD project on logged over forest gave higher economic value than pulpwood plantation at compensation prices US$ 9 and 12 tCO2-e-1 (both on conservation and preservation logging scenarios).

Abstract

The paper describes economic valuation for the Cidanau watershed area of West Java in Indonesia. In this area natural resources deterioration has occurred even faster after the Asian Financial Crisis. The deforestation area and pronounced soil erosion seems to go unhindered because of land use competition among the residents for agricultural space, housing, etc. In order to prevent the area from further degradation, the purpose of this paper is to carry out quantitative evaluation which also attempts to raise the environmental awareness of residents, as well as visitors to the area. Questionnaire surveys were conducted and analyzed according to the Contingent Valuation Method (CVM) and the Travel Cost Method (TCM). The results show all respondents held good attitudes towards the efforts of environmental conservation, but responded negatively if they had to contribute to the environmental service payment. Visitors to the Anyer Beach acted differently because most of them come from faraway locations and have little knowledge of the watershed. However, the Anyer Beach recorded an environmental valuation of about Rp840 billion, which is a potential source for the service payment of Cidanau watershed.

Abstract

One effort in improving productivity and regaining the function of forest and land which have been degraded is national movement on forest and land rehabilitation (Gerhan). This movement constitutes an investment. In general, an investment should always involve the expectation for obtaining benefit/profit, either directly or indirectly. The objective of this research was to estimate the magnitude of total benefits value resulting from Gerhan in Sub Watershed of Tirto located in Central Java Province. Benefits value was calculated by using market price approach, replacement cost, procurement cost, and contingency valuation methods. Economic value which was calculated consisted of direct use value, indirect use value, and non use value (option value and existence value). From rehabilitated land, as large as 1,463 ha (planting year 2003–2008) in the Tirto sub watershed, the present worth total economic value resulted from was Rp331,223,929,621 with analysis period of 15 years (cutting cycle of woody crop) at interest rate of 15% or Rp15,093,367 ha-1 year-1. Such value consisted of direct use value 92.21%, indirect use value of 6.64%, and non use value of 1.15%. These benefit value was calculated on the basis of planting success rate, namely 88% for woody crops and 85% for multi purpose tree species.

Abstract

This paper aims to analyze the impact of non-forestry policy, especially energy related macro policy decisions, on poverty and use levels of natural resources. As core indicators, this analysis employs ‘number of households below the poverty line’ and ‘area of deforestation’. Impacts are analyzed in an agent-based simulation model for 6 districts of East Kalimantan, one of the Indonesian natural-resource rich provinces on the Island of Borneo. Simulation results partly suggest that the policy decision of June 2008-politically known as decreasing fuel price-had nearly no impact on deforestation amplifying that the dominating driver of deforestation is large scale logging and mining operations, as well as potentially illegal activities. While, it reduced the number of poor people-those mostly living within and around forest area-by about 5.4%. Due to seasonal income, this policy-related impact is likely to be periodically lower. During the harvest related period, many households are able to lift their income above the poverty line. This seasonal fluctuation in poverty could help optimize public funding by spreading it over longer periods and by pausing direct transfers during such natural periods of poverty reduction. There is no significant implication for forestry or forest management since the model could only deal with small scale forestry.
