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.

Abstract

The expansion of oil-palm plantations in Indonesia is often blamed as the driving causes of deforestation and impacts on environmental changes including the destructed biodiversity. Our understanding regarding environmental impacts on biodiversity is still limited. We address this issue by examining the diversity of butterfly and bird species under two type habitat conditions in Central Borneo. We calculated the butterfly and bird species number, richness, evenness, similarity, and composition inside the established oil-plantation area comprising four large-scale plantations and seven smallholding plantations, as habitat after plantation establishment.  In comparison, we did so similarly inside secondary forest and shrubs, as habitat before oil-palm plantation establishment.  Our results revealed that the habitat after plantation establishment exhibited a higher number of butterfly and bird species than the habitat beforehand.  However, the richness, evenness, and similarity indices for the species revealed variations, which were affected by dominant species in two habitats.  The establishment of oil-palm plantation brought about significant impacts on the composition of species and affected the species similarities between two habitats. The oil-palm plantation landscape and reserved forest vegetation were essential in supporting diversity and ecological role of species on habitat condition after oil-palm plantation establishment.

Abstract

Acacia nilotica is an invasive species in the Baluran National Park. The spread of A. nilotica is a serious threat that can disrupt the function of savanna ecosystems in providing food for herbivores and eventually led to a decrease in wildlife populations of herbivorous. The growth of A. nilotica invasive species is influenced by some environmental factors. In order to prevent the spread of A. nilotica, a model can be formed to prodict the species distribution based on the environmental factors namely generalized linear models. This research used the data from Siswoyo’s research in 2014, which consisted of environmental data and distribution of A. nilotica. The results showed that there were five environmental variables that significantly affect on the spread of A. nilotica invasive species. The variables included elevation, surface temperature, normalized difference vegetation index, normalized difference moisture index, and the distance from the river, with p-value less than 0.05. The accuracy of the prediction model on the spread of A. nilotica using GLM was 97.22% and the Area Under Curve (AUC) value was 0.981.

Abstract

Independent smallholders who manage their own oil palm plantations without receiving technical assistance and agricultural inputs from oil palm estates or government have been  increasing rapidly in Indonesia in recent years. However the magnitude of their impacts on tropical forest deforestation remains largely unevaluated.  The objective  of this study was  to explore the history of land use, and the changes in land cover and status since the onset  of  oil palm plantation activities. The study was conducted from March to April 2016. Surveys  were carried out in 30 ha of independent smallholder oil palm in  Kampar District, Riau Province.  To identify the land status, the Agreed functional forest classification (TGHK) and Provincial land use planning (RTRWP) maps were overlaid on images of the area of independent smallholder oil palm. Landsat images three years before oil palm was established were used to assess forest cover changes.  Furthermore, oil palm smallholders and elders of the local community in the research area  were  interviewed to identify land use prior to oil palm.  Our results showed that, based on land  status, 47% of  the area of independent smallholders’ oil palm derived from logged forest; that is the land  changed in status from forest to oil palm plantation.  The other 53% of oil palm area derived from non-forested land. The land use history before the establishment of independent smallholder oil palm mostly comprised general-purpose field activities and former forest-felling (forest concessions). The land cover  before conversion into oil palm comprised rubber plantation, secondary forest, and shrub cover. From the results of our survey, we conclude that most of the oil palm plantations planted between  1990 and 2002 have their origins not in primary forest, but rather in  degraded secondary forest, former fields, and shrub-land. These results imply that conversion of forest area into oil palm plantations is not the direct cause of deforestation in the tropical forests of Kampar, Riau Province.

Abstract

Wehea forest is a highland of tropical rain forest on East Kutai Regency in East Kalimantan. The community especially Wehea ethnic in Nehas Liah Bing Village is well known for their traditional wisdom in utilizing the forest resources. Wehea Forest Area is a cluster of Maput and Pendreh land systems, and both land systems are irregular hilly regions that have steep to very steep slopes. Because of the uniqueness of biodiversity, landscapes, and traditional wisdom of Wehea ethnic the forest has been declared as forest reserve. This study aimed to assess the natural resources, culture, and participation local community as potential for nature based turism development. The result showed that the Wehea forest has biodiversity of flora dan fauna. Species of flora which are often founded are families of Dipterocarpaceae, Annonaceae, Lauraceae, etc. Fauna potentials are not less important and interesting than flora ones. There are several species which have endangered and protected status. The uniqueness of natural forest landscape really supports to various ecotourism activities. Wehea forest wealth also comes from local community presence. Their awareness is relatively high about Wehea forest existence, especially communities in Nehas Liah Bing. Dayak ethnic of Wehea forest has unique culture to be developed as tourist attraction. Dayak ethnic communities in Miau Baru are Kenyah and then community in Makmur Jaya which was once a transmigration village of Java ethnic. Both communities in the village are familiar about the Wehea forest existence. Culture value diversity, awareness, and participation of local communities become strong capital to develop natural based turism and are expected to contribute to economic diversification region.

Abstract

The topic of social capital has been gaining many concerns from social researchers throughout the world, especially in collective action perspective. This study aimed to describe the organizational activities of the local forest management practices (parak and rimbo) as a social capital in collective action perspective. The research method is a case study of Koto Malintang and Simancuang people in West Sumatra. Collecting data was conducted by unstructured interviews, field observations, and document studies. Data analysis uses categorization and coding, document analysis, and historical analysis. Our findings were described in the context of decision-making, resources management and mobilization, communication, and conflict resolution. Collective action for decision-making involved the acquisition, allocation, and distribution mechanisms to divide land and forest product among local people. In the context of resources management and mobilization, they applied kinship relations among families, sub-clans, and clans to manage their resources. They then communicated their needs in any formal and informal meetings. When a conflict occurred in related to forest utilization, they applied an adat court to make a win-win solution. Nevertheless, the challenges of collective action are still about the resources availability, benefit equity, and external supports

Abstract

Utilization conflicts among users threatening the sustainability of forest management. This study is to determine the intensity of conflict and the sustainability of forest management in FMU Meranti by integrating the convergent parallel mixed method and Rapid Land Tenure Assessment. Data was collected through interviews with key informants, literatures, maps, documents, and histories studies; as well as focus groups discussions in eight villages around the FMU Meranti. The results showed that the people's bundle of right, the interaction and social capital, dispute against the coorporation's financial modal. Generally, the interaction and social capital elements are owned by the local community, while the financial modal is owned by the permit holder and the local elite. Based on the power analysis on each object, the power of both community and permit holders are equally strong. The conflict intensity is subdivided into three conflict categories, i.e.: open (31%), appear (44%), and latent conflicts (25%). The special area (wilayah tertentu) and open access area are highly prioritized, that need conflict resolution. The existence of the environmental damages, unclear ownership rights, lack of stakeholder supporting, and non-optimal institutional performance lead the sustainable forest management to bad category (40.6%).
