Abstract

The recovery of land cover/use after the disaster is sometimes disorderly, especially in developing countries. It is necessary to continuously monitor the progress of land cover/use recovery after disaster in order to sustain vegetation around estuarine and coastal areas. The purpose of this study was to assess the recovery progress of vegetation around estuarine and coastal areas after the Indian Ocean tsunami using a simplified method which consisting Google Earth and visual photo interpretation. Vegetation areas were able to be detected with high accuracy (80%−100%) using simplified method which consisting Google Earth and visual photo interpretation. We were able to show that all most of area including mangrove forests recovered relatively smoothly. However, the area which has a large vegetation areas have not enough recovered, which reached to half or less than half compare with before tsunami. This may be significant in affecting the role of the coastal ecosystem and bioshield. A large number of small mangrove patches (less than 0.1 ha) were able to found around ponds, a number that rapidly increased after the tsunami. Some site in 2013 was double that in 2004. Fish farmers might have planted them for supplying nutrients to ponds and maintain the water quality. Dozen years have passed since the 2004 tsunami, and it might be time to more focus on the recovery of large vegetation area.

Abstract

Line intersect method (LIM) emerged as one of the effective and efficient post-harvesting assessment methods. LIM was being widely used to estimate logging residue of plantation forest in the temperate zone. This method has not been used in tropical forest plantations, including teak forests. The study was carried out to determine the best design of LIM for assessing logging residue in the teak plantation. The circular and rectangular plot was used in this study.  A hundred percent logging residue inventory was carried out on each plot.  Then, one and combination of two and three line intersects per plot were placed on each plot. Bias, precision and accuracy criteria were calculated in order to compare the designs. The study found that estimation of logging residue volume using LIM was biased and tended to overestimate. LIM design with two lines combination per plot was the best design for assessing logging residue of the teak plantation.

Abstract

This study aimed to analyze policy effectiveness of loan for delaying timber harvesting for smallholder private forest business (Pinjaman Tunda Tebang Hutan Rakyat; hereinafter will be referred as PTT-HR). The analysis will be used to provide recommendations for improving PTT-HR scheme included scaling out and scaling up of the scheme for improving economic benefits and supporting smallholder private forest business as well as for strengthening farmer’s welfare. Field survey was conducted in October–November 2013 in two districts in Central of Java, Indonesia namely Blora and Wonosobo District as recipient of PTT-HR from Public Service Agency for Forest Development Financing Center (BLU Center of P2H) Ministry of Forestry, Republic of Indonesia. The results showed that PTT-HR policy has implemented effectively based on evaluation parameter derived from the objectives of policy namely the age of the stands for loan collateral, the capabilities for improving farmer’s welfare, utilization of loan, perception of the farmers regarding to the ease of the process and purpose of loan utilization, and the capability of loan repayment. However, this research has not been answered the aspect of PTT-HR policy implementation efficiency.

Abstract

The Indonesian Government has empowered communities that are living adjacent to forests, but at the same time, protection forests are highly encroached by the local community. In response, our study aims at formulating strategies of community empowerment in protection forest management. Data collection through participatory observation, questionnaire surveys, interviews, and focused group discussions were conducted in the surrounding communities of protected forest areas in Sumbawa District, Indonesia. A combination of descriptive, participatory, and explorative approaches were used for data analysis. The knowledge of local communities on protection forest conservation was found to be on an average level, while their attitudes towards conservation were assessed as being on a higher level. Community empowerment programs implemented by the government were shown to have no significant effect on knowledge improvement, but they were more effective in changing the community's attitudes regarding protection forest management. Local communities were shown to be willing to conduct conservation activities as well as looking for cash income. Therefore, our study suggested that community empowerment programs should link forest conservation with income opportunities for local people, such as implementing conservation agriculture (e.g. agroforestry), partnerships in the production and sale of non-timber forest products, and be conducting clearly reward and punishment for communities.

Abstract

This study analyzes the pattern and change of land use and land cover (LULC) during 2000−2015 and its relation to population and poverty in the semi-arid region of Indonesia in Timor Island, on the country border to Republic Dominica Timor Leste (RDTL). The analyzes employ visual interpretation using GIS to aid classification of Landsat imagery and find 14 classes of LULC.  The matrix of LULC change for the 15 years period indicates a substantial deforestation in which 1,309 ha or 13% of the forest in year 2000 has disappeared. In detail, 2 ha (7%) of primary mangrove forest has became mixed farming and 1,307 ha (19%) of secondary forest has become shrub. Within the nonforest classification, 1,288 ha (17%) of shrub in 2000 has turned into savannah, and 15 ha (10%) of shrub swamp has turned into bare land, while at the same time human settlement has expanded by 118% from the settlement area in year 2000. Spatial pattern of LULC changes in the study area for 15 years are dispersed, and tend to remained in the middle area that dominated by mix agriculture. The forest cover is weakly associated with level of poverty and rural population in the study area. However, the two latter variables were not significantly associated with deforestation.

Abstract

Forest is an ideal ecosystem for a hydrological cycle, however converting forests to agroforestry or rainfed agriculture is inevitable.  This study elaborates a hydrological response of infiltration, runoff, and soil moisture in three land uses at Renggung watershed.  Field measurements were conducted in 2014−2015 in those system with soil types of entisols at upstream, inceptisols at the middle, and vertisols at downstream.  Results showed that constant infiltration rate at upstream in forest was 55.6 cm hr-1, in 15−30 years agroforestry was 32.4 cm hr-1 on average and in rainfed was 26.4 cm hr-1.  Infiltration in agroforestry at the middle and downstream was 16.8 cm hr-1 and 11.2 cm hr-1, respectively, while in rainfed was 2.4 cm hr-1 and 4.8 cm hr-1.  Runoff at upstream with 29.3 mm hr-1 rainfall in forest was zero, in agroforestry was 0.026 mm hr-1 and in rainfed was 0.071 mm hr-1.  Runoff in agroforestry at the middle and downstream with 37.1 mm hr-1 and 23.8 mm hr-1 rainfall were 0.045 mm hr-1, and 0.026 mm hr-1.  There was a half and one third of that in rainfed.  Soil water content in successive order from high to low was in forest, agroforestry, and rainfed.  So, capacity of agroforestry in sustaining the hydrology cycle was in between forests and rainfed agriculture.

Abstract

Indonesia's natural forest has been persistently declining, even with the fastest rate in the world, regardless of various efforts to stop the decline or at least to reduce the rate significantly. At the same time, development of plantation forest has been very slow. Amongst the various causes of the natural forest loss that have been identified, financial nonprofitability was not one of them. That being said, the fundamental reason as to why utilization of natural forest for timber production will not survive in the long run is because of financial nonprofitability.   In order for a business to stay in the industry of the natural forest utilization, the government should provide financial incentives using public's money. Hence, the public support for the forestry is vital for the survival of the industry?. However, improper implementation of forestry laws can have damaging impacts to the public's perception and support.   Moreover, the five policies, namely forest land establishment, fees, and royalties, log export ban, certification, and forest management unit establishment, which have failed to deliver sustainable natural production forests, are shortly discussed. Finally, the more appropriate approach of natural forest utilization is basically not as a sustainable forest management but rather as the optimal timber mining, which consequently requires different set of policies.
