Abstract

The payment for ecosystem services (PES) scheme in the Cidanau Watershed, Banten Province, Indonesia has not yet quantified and reviewed its livelihood impacts on its providers after two decades of implementation. Therefore, this study maps the livelihood sustainability of PES farmers and non-PES farmers in the Cidanau Watershed using capital indexes based on the five livelihood capital assets of the DFID’s sustainable livelihood framework. The research used a quantitative method to formulate the livelihood capital indexes (LCI) as approximates to the subjects’ livelihood sustainability based on their livelihood information and draws implications from the results thereof. A total of 168 agroforestry farmers both from PES and non-PES groups were interviewed across 12 villages in the upstream area. The results show that both PES and non-PES groups share the same pattern of capital assets sustainability with the PES group having a slightly higher human capital asset. The overall LCI calculated for the PES and non-PES groups are 0.445 and 0.48, respectively. The livelihood of both groups is deemed as not yet sustainable. The farmers would have to develop their financial and human assets to attain more sustainable livelihoods and prepare themselves for adopting new types of PES in the future.

Abstract

Agroforestry is a cropping pattern that is commonly applied to private forest management in Indonesia. Agroforestry based private forest is a land-based silviculture that incorporates forestry plants with agricultural crops, plantation crops, and multi-purpose plants. One of the felling techniques used in agroforestry based private forests is the sandat-felling technique (SFT), which is a rope-assist felling technique. The felling technique was used to protect the remaining stand of the agroforestry based private forest. This technique is an innovation in the harvesting of agroforestry based private forests in Indonesia. The time consumption and productivity of this technique are not yet known. This study aims to assess the working time and productivity of SFT in agroforestry based private forests in Probolinggo, East Java, Indonesia. The observed tree-felling technique included rope installation and tree-felling operations. The performance of the SFT was evaluated by analyzing its working time and productivity. The results of the study showed that the total working time of the SFT was 8.65 minutes tree-1, which consisted of 33.34% for rope installation and 66.66% for felling operation. The productivity of the SFT was 2.02 m3 hour-1.

Abstract

This study analyzes the roles and positions of stakeholders in decision-making processes within the National Forestry Council (Dewan Kehutanan Nasional, DKN), a forest-related multistakeholder platform in Indonesia. It considers stakeholders’ power, legitimacy, and urgency. The research employed a qualitative case study, centered around in-depth interviews with 27 key informants with diverse backgrounds involved in the DKN. The study found that despite being designed to facilitate democratic and inclusive decision-making, the engagement of stakeholders in the DKN is heavily dominated by powerful government actors. Several stakeholder groups, such as NGOs and academics, may actively participate in decision-making processes, but they do not meaningfully influence and capacity to determine the organizational policy directions. This is related to an imbalance in the distribution of power among stakeholders in DKN. Even though this organization promotes the principle of inclusivity, the reality is that the presence and influence of the government are still the dominant factors in determining policy directions. This study confirms the importance of the stakeholder salience analysis approach in the context of multistakeholder initiative organizations such as the DKN, which allows recognition of power dynamics and domination among stakeholders within the DKN so that decisions made truly reflect the common interests of all parties involved.

Abstract

Felling and skidding are essential in the timber extraction process. But on the other hand, residual stand damage can’t be avoided. This study aimed to analyze the impact of conventional and improved felling and skidding techniques on residual stands in natural forests. Three observation plots were developed to identify the types, numbers, and criteria of residual stand damage due to both techniques. The criteria were categorized as a) minor damage (<25%), b) moderate damage (25–50%), and c) major damage (>50%). It showed that the conventional felling and skidding technique caused damages of 14.92% dominated by tree crown damage and 16.70% dominated by stem wounds, respectively. The residual stand damage due to conventional felling and skidding technique was 31.62% categorized as medium damage. Meanwhile, improved felling and skidding techniques caused damage of 9.89% dominated by broken trees, and 10.27% dominated by stem wounds, respectively. The residual stand damage due to improved felling and skidding technique was 20.16% categorized as minor damage. The improvement techniques can minimize residual stand damage by 36.24%. Therefore, a good understanding of forest concessionaires regarding RIL principles is necessary for achieving sustainable timber harvesting

Abstract

Forest and land fires in Indonesia have serious impacts on many aspects, including the environment, health, economy, politics, and international relations. They cause haze pollution that extends to neighboring countries and peatland degradation. Despite extensive research and mitigation efforts, forest and land fires continue to occur and cost lives. Therefore, effective management and mitigation strategies are required. This research developed a web-based knowledge management system (KMS) using the Laravel framework as an effective forest and land fire mitigation platform. The KMS aims to support decision-making, facilitate knowledge exchange, improve coordination between stakeholders, and expand access to relevant information, while maintaining the sustainability of forest and land resources in Indonesia. The KMS evaluation results cover two important aspects: blackbox evaluation and performance evaluation. The blackbox evaluation showed that KMS provides knowledge retrieval features based on expert knowledge. The performance evaluation revealed that the KMS provides easy and quick access to information on forest and land fire prevention and management. Thus, this research has great potential to help overcome the problem of forest and land fires in Indonesia and protect the environment and society from their adverse effects.

Abstract

Forests once deforested through mining losses its rich biodiversity. The re-opening of open-pit mining corporation in 2011, in the small village of Bato-Bato, Narra, Palawan had caused deforestation, floods, and low rice harvest. This study determined the nickel content in topsoil and native dominant plants in mine-tailings. Field data collection and laboratory analysis methods were used in this study. Nickel content in topsoil (2 kg replication-1 site-1) was analyzed using X-ray Flourescence (XRF). Inductively Coupled-plasma–Optical Emission Spectrometry (ICP-OES) determine nickel in dominant plants (200 g replication-1 site-1). Normality of data was determined by Pearson coefficient of skewness test. Significant difference on the nickel content in plant tissues was analyzed using Kruskal Wallis test, analysis of variance, and Tukey post hoc test for nickel in soil. Native dominants are National Seed Industry Council Rice cultivar 218, Philippine Seed Board Rice cultivar 18, and carabao grass. The nickel content in native dominant plants is higher in comparison with the average nickel content in plant tissues and the nickel content in topsoil is high in comparison with the average nickel content a topsoil should contain. Prevention of leaching of nickel during flood is recommended.

Abstract

Waqf-based forests can conserve the forest ecosystem by applying waqf principles. This initiative has been implemented in several places in Indonesia. The limited funds available for waqf-based forest development require nazhir to carefully choose the best location so that the asset can function optimally. However, no specific research has been conducted to guide the selection of the best location for this purpose. This study aimed to identify potential criteria to help determine the best site for developing a waqf-based forest. Several methods were used to collect the necessary data, including literature reviews, in-depth interviews, field observations, and focus group discussions. This study identifies four crucial criteria when selecting the best locations: a) legal, b) physical and biophysical, c) high conservation value and benefits, and d) management. In addition, each criterion has sub-criteria. Among all, legal issues receive the highest highlight as unresolved regulations can affect a forest's ownership and function. This study was the first to discuss these criteria. Future research should quantify the criteria suggested using GIS and conduct more field observations in existing waqf-based forests in Indonesia.

Abstract

The success of rehabilitation has altered environmental conditions from critical land to new habitats for living organisms. One of the representative and sensitive mesofauna to environmental changes is Collembola. Various vegetation cover almost all of the rehabilitation area, which has impacts on microclimate and soil quality as important factors to Collembola existence. This study investigated the diversity and abundance of Collembola and its relation to environmental factors on various land covers, including teak, grass, and mixed stand land cover. Data were collected in an observation plot of 20 m × 20 m using purposive samples, including environmental measurements, Collembola collection, and soil samples for physical and chemical analysis. The results showed that different land covers affected the abundance and diversity of Collembola, even though the statistical analyses of TLC, GLC, and MLC were not significantly different. However, TLC has a higher litter thickness and organic material than the other land cover types. A few families of Collembola, such as Cyphoderidae, Brachystomellidae, Katiannidae, Isotomidae, Oncopoduridae, and Isotogastruridae, show their correlation to climatic and edaphic factors in a certain land cover.

Abstract

As a soil-living organism, soil mite presence is important for ensuring the sustainable land. Intensive management practices in forest land drive a change in its community structure. A field study was conducted in Wanagama Education and Research Forest I, Gunungkidul District, Yogyakarta Special Region Province, Indonesia, to assess the role and impact of the different forest management practices on the soil mite community. Soil samples from 15 representative soil sites were taken from the agroforestry, mixed-forest, and pioneer community forest. Collected individuals from August to October 2021 were taken by Berlese-Tullgenn Funnel and identified to morphospecies level. A total of 758 individuals of soil mites were recorded during the study period. Out of these, 21 individuals from agroforestry, 288 individuals from mixed-forest, and 449 individuals from pioneer community forest. Results of the study revealed the occurrence of 3 taxa from 36 morphospecies of oribatid mites occurred in the areas. The Shannon diversity indices of oribatid mites were 1.831, 1.424, and 0.867 in mixed-forest, agroforestry, and pioneer community, respectively. The similarity indices showed there was a similar diversity in agroforestry and mixed-forest, either in pioneer community. Through one-way ANOVA analysis, we stated that differences between of three management practices significantly affected soil mites, especially oribatida rather than prostigmata and mesostigmata.

Abstract

An understanding of the local traditional ecological knowledge (TEK) of a region is crucial to understand the interactions between indigenous societies and their ecosystems. To understand the TEK of Indonesian indigenous people and its influencing factors, we evaluated the Tengger people’s knowledge and conservation awareness regarding culturally important plants (Javanese edelweiss). We interviewed 641 people from seven Tengger villages located adjacent to Bromo Tengger Semeru National Park (BTS), Indonesia. We developed 31 models to examine factors affecting edelweiss knowledge and calculated the Akaike information criterion values to select the best model. Sex, education, and residency duration were significant predictors of edelweiss knowledge. Men, individuals with higher levels of education, and those who had lived in the area for a longer period of time had higher levels of edelweiss knowledge. Our findings confirm that communication within the community and external information sources, such as media and formal education, are involved in knowledge transmission related to edelweiss. Educational activities for local people can be used to disseminate TEK through formal education in schools and informal education programs conducted by the national park managers.
