Abstract

Land use and management must be carried out in a way that ensures the sustainability of land ecological function. The presence of natural enemies that suppress pest populations is an important component of the ecological function. Monitoring the presence of natural enemies and avoiding silvicultural activities that threaten the presence of natural enemies are important aspects of land management. This study investigates the presence of natural enemies on three different lands: agroforestry, community forests, and pioneer lands. Monitoring was carried out during three months at three types of land use by using observation plot in the square form of 20 x 20 m2. Insect collection in the field uses pitfalls and sticky traps which are placed using a grid and a diagonal method, respectively. Phytophagous insects, such as leafhopper, flies, thrips, aphids were surveyed. Hymenoptera natural enemies, predators (Formicidae) and parasitic wasps (Trichogrammatidae and Scelionidae) were obtained. The results show that community forests and pioneer lands are support the existence of Formicidae. This study indicates that in the agroforestry there are variations in population of Formicidae based on the period of on-going land management. Agroforestry provides a more suitable place for the existence of Trichogrammatidae and Scelionidae.

Abstract

The controling of forest sustainability and preforest ecosystems in achieving stability of forest ecosystem require the identification of biophysical indicators, anthropological, and technological. The significant degradation of Quercus suber formations in forest massif of Tlemcen (Algeria) are imposed by both climatic factors, the fires, the overgrazing land, anthropogenic aggression as well as by ineffective management. The making of a reference matrix would make possibility the identification of probable hazards and risks. This study aimed to identify the understanding how the mode of operation of a system to identify failures and treat, and the create the intention of eliminating or minimizing the associated risks. This matrix will consist of relevant indicators which easy guide to estimate and following the understanding of the forest degradation process in Algeria. The FMECA method allowed identification of 20 main defective targets which be grouped into 3 categories namely: technical, ecological, organizational, and facilitate of remediation. Each error can be scored and action plans can be prioritized, allowing different with all forest sector players to better understand the degradation of this natural space in order to implement efficient and appropriate remediation plans.

Abstract

This article aims to describe the livelihoods of communities around the mining area through cases in Mulawarman Village, Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan Province, Indonesia. This research uses a qualitative method with a case study approach. These findings show that the vegetation index value in Mulawarman Village degraded from 2014 (0.35) until 2019 (0.33). It shows forest degradation, which affects the livelihoods of rural communities that depend on agriculture or forestry. The leading cause of the decline in the vegetation index value is the expansion of coal mining activities. Indirectly, coal mining activities have limited the ability of the Mulawarman village community to access natural resources. Some residents of Mulawarman village have decided to sell agricultural land and move to other places. However, residents still survive to live in Mulawarman village by starting livestock and trading businesses to maintain their livelihoods.

Abstract

The application of carrying capacity has the potential to protect tourist areas, both natural and cultural, and it is also related to the lifestyle of the local community, as well as the potential of tourist destinations. The condition of the people of the Kei Islands who are still experiencing conflicts of interest in several areas causes a development that is not according to plan or can even change or destroy the character of natural and cultural resources. The purpose of this study was to analyze the condition of social values ​​related to current social carrying capacity with conditions 10 years ago. The number of respondents was 600 people who come from 10 community groups. Primary data were obtained through filling out a list of questions by respondents using a closed-ended questionnaire by applying the “one score one indicator scoring system”. Data analysis was carried out in a quantitative descriptive manner based on the average value of each indicator. To find out the difference between the current condition and the condition 10 years ago, a paired t test was conducted. The results showed that the local community's response to tourism development activities both now and 10 years ago felt positive and negative impacts. The conditions of social situations that produce positive impacts are condusive situations, associations, cooperative situations, and productive collaborations, while the negative ones were dissociation, conflict, and war. Communication and economic aspects must be the attention of the parties so that conflicts of interest can be reduced so that the development of ecotourism in the Kei Islands can be more optimal.

Abstract

The sustainability of tourism-based livelihoods can be threatened when a crisis occurs. Thus, people’s resilience during crisis is a significant factor for people to maintain livelihoods as it is a contributing mechanism for people to escape from crisis. This research examines how the Nglanggeran community sustains their livelihoods by utilizing their natural resources as a strategy to survive Covid-19 pandemic between 2020 to 2021. This study uses an ethnographic approach. The data collection process was carried out through participant observation and in-depth interviews with 14 former migrant workers and who now live in Nglanggeran village. The focus of the analysis in this study is the strategy of the Nglanggeran community in maintaining their livelihoods by utilizing their land. The analysis process uses thematic analysis. People who own paddy fields are more likely to survive than those who plant trees for timber on their land. What the Nglanggeran community does is important in maintaining their resilience and as a survival strategy for the local community. Tourism activities do not have to displace traditional livelihood activities on local people's land, rather land use can be optimized to support sustainable livelihoods. While they can optimalise land use, this does not increase their quality of life. They have survived but their livelihoods remain vulnerable.

Abstract

This study analyzes the vegetation index and mangrove forest utilization through ecotourism development in Guraping and Dodola Island of North Maluku Province. This research uses a remote sensing approach through Landsat 8 Operational Land Immaginer (OLI) from 2013 and 2021, calculated based on the Normalized Difference Vegetation (NDVI) algorithms. This study indicates that ecotourism development can preserve the mangrove forest and generate the economic and social benefit of the local community. Otherwise, the vegetation index in mangrove areas from 2013-2021 needs to be considered seriously as the primary data to optimize the management of tourism destinations. Through the case of Dodola Island, the increased number of vegetation in 2017 experienced significant changes and threatened the sustainability of mangrove ecotourism. Thus, the mangrove monitoring needs to be optimized to anticipate the unsustainability of mangroves, which determines the sustainability of tourism in North Maluku Province. This study offers an idea to involve the local community in conserving the mangrove area through a controlled and sustainable rehabilitation program instead of economic activity purposes. The findings indicate that the existing condition of the Guraping mangrove forest in 2021 is classified as moderate compared with mangrove ecotourism in Dodola Island with sparse criteria based on the Decree of the Minister of State for the Environment in 2004, This research suggests adopting the community-based ecotourism mangrove development through collaborative advantages of all tourism stakeholders.

Abstract

Bajakah and akar kuning are known as traditional medicine from peatlands, which are usually extracted from their natural habitats. Over extraction and illegal cutting have become a threat to the extinction of both species. Therefore, propagation and cultivation of those medicinal plants are necessary to be conducted outside forest areas to meet the demand of raw materials of traditional medicine and minimize the risk of species extinction. The experiment of stem cutting propagation of two bajakah species (Uncaria acida and Salacia sp.) and akar kuning (Fibraurea tinctoria) were conducted separately in two different nurseries. The results showed that stem cuttings of woody liana could produce more than one new shoot. The new shoots of U. acida and Salacia sp. grew after eight weeks, with a survival rate of 96% and 50%, respectively. The survival rate of F. tinctoria stem cutting after six weeks was 83.3%. These indicate that bajakah and akar kuning can be propagated and cultivated to support the bioprospecting of traditional medicinal plants. Despite some challenges, such as limitation of akar kuning and bajakah population at the pole stage in their habitats, it is an initial step of a long process of bajakah and akar kuning bioprospecting.

Abstract

Fuelwood commercialization activities provide a source of livelihood in Nigeria. Despite its economic significance, the industry has been kept out of the formal economies due to a lack of supportive data on the structure and characteristics of the industry. This study investigates the structure of the supply chain and examines the chain actors' roles and functions to understand the issues within the supply chain activities. Data were collected through key informants' interviews and observations. The study found that fuelwood business activities were conducted formally by licensed actors and informally by non-licensed actors. Benefits received and issues experienced by actors were related to the formality of the business. Heavy reliance on natural forests for fuelwood production among chain actors can add pressure on the forest resources and ecosystem. Therefore, significant intervention is needed for the industry which includes policy and programs related to fuelwood plantation and management, government support, licensing education, and collaborations among all stakeholders to improve supply chain activities.

Abstract

Human activities, which have interfered with the ecological system, have led to global warming. This has led to the release of carbon stocks into the atmosphere, thereby reducing the function of carbon sinks in places with vegetated land. With increased human activities, vegetated land will soon become non-vegetated. This is because the increased human activities have led to the absorption of higher amounts of carbon in the atmosphere than the required level. Therefore, this study aimed to estimate land cover on carbon stocks in Prabumulih City, South Sumatera Province, Indonesia. The study employed a random field survey using a dynamic system, with the results showing that land cover consisted of oil palm plantations, mixed plantations, grass, swamp shrubs, and rivers. However, the area was dominated by rubber plantations, and as a result, the carbon stocks continued to decline. For instance, in 2008, the level of carbon stock was 2,438.72 Gg and fell to 2,190.85 Gg in 2020, indicating a 4.8% decrease. It is projected that by 2030, the carbon stock in land cover will be 1,988.07 Gg.

Abstract

The success of forest rehabilitation initiatives depends on community engagement; thus, it is important to understand community opinions toward forest rehabilitation initiatives. However, the available literature is sparse, as most research focuses on forest rehabilitation research, frequently only on planting performance. We scrutinized residents' opinions of the forest rehabilitation initiative using the extended Theory of Planned Behavior framework variables, i.e., behavior (B), behavioral intention (BI), attitude toward behavior (ATB), perceived behavioral control (PBC), subjective norm (SN), moral norm (MN), perceived risk (PR), and self-identity (SI). Those factors were used to cluster residents into various groups using the k-means clustering method. 307 completed questionnaires were obtained. We found that residents were clustered into two distinctive groups: active supporters (AS) and passive supporters (PS). PS was dominant in the community (61.9%). They were characterized by less agreement in perceiving the adverse impacts of forest degradation, less intent and engagement in forest rehabilitation programs. In contrast, AS was more receptive to forest rehabilitation initiatives. These results confirm that residents are heterogeneous in opinions and interest in forest rehabilitation initiatives. Therefore, forest managers should design effective policies and alternative approaches to ensure the success of forest rehabilitation programs based on those distinctive groups.
