The COVID-19 pandemic has shocked people all over the world, including Indonesia. Various impacts have been felt due to the pandemic, including the many lives lost, obstacles to economic activity, limited community activities in general, to a decline in national tourism activities. The space for people to move at that time was limited, especially when they were infected with COVID-19. This study aims to identify the benefits of forests to improve public health recovery post-pandemic. Data collection was carried out in February-June 2023 by literature review and was analyzed qualitatively. Indonesia has successfully passed COVID-19 since December 2022, while health protocols are still being implemented. After going through a difficult period, people need health therapy to face their activities properly. The benefit of forests from environmental services in several countries is considered capable of being an alternative to increasing people’s enthusiasm with health therapy through healing forests. Many ecotourism activists in Central Java offered tourism services for beautiful landscapes, kind of waterfalls, mountainous landscapes, and the serenity of forests. Visitors welcome the opportunity to enjoy beautiful natural offerings and soothe the soul. It is in line with the high demand of ecotourism spots post pandemic, which form a close relationship between the triple bottom line from an ecological, social, and economic standpoint toward the environment sustainable development.

Planktonic organisms are the main biotic components of the food chain of aquatic ecosystems. Little is known about the impact of multiple stressors on plankton community response in mining areas. This study aimed to elucidate the alpha diversity of zooplankton and phytoplankton in different stream networks associated with mining activities in the Molore watershed, Southeast Sulawesi. The research was carried out by taking samples for water quality and plankton analyses in four streams in November 2021 and November 2022. A rarefaction curve approach was used to assess the species richness and diversity trends of the region. Streams were clustered using the Bray-Curtis similarity index of alpha diversity indices, such as the Shannon-Wiener, Simpson, Margalef, Pielou, and Berger-Parker indices. We found six species of zooplankton only in three sites and 21 species of Phytoplankton in the class of Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, and Euglenophyceae across the landscape gradient. The present study showed that the lowest value of the Shannon-Wiener diversity of the plankton community was 0.48, while the maximum expected value based on individuals’ rarefaction curve was 2.24. Species richness is in line with cluster analysis, which shows the similarity of stream groups according to the level of environmental pressure, indicating a valuable ecological indicator for stream management.

Published: December 2023

The tea plantation of Sri Lanka heavily relies on land suitability and proper cultivation practices. Although the High Grown Region (HGR) contributed a high proportion of tea production to the supply chain. This study evaluates the land suitability of tea plantations and potential challenges that hinder sustainable tea production of HGR selecting the GN divisions in the Kothmale DS division. In this study, Analytical Hierarchy Process and descriptive statistics were used as data analysis techniques. Results revealed that 6.33 sq km (45.6%) is very highly suitable, 7.02 sq km (50.7%) is highly suitable, 0.51 sq km (3.6%) is moderately suitable, and 0.11 sq km (0.07%) is unsuitable for tea plantations. However, despite the land suitability, tea production has been gradually declining due to various factors. soil erosion, old seedling tea bushes, the spread of disease, the government’s ban on chemical fertilizer and pesticides, the escalation of fertilizer and other input prices due to inflation, inadequate subsidy schemes for replantation, and labor scarcity. To address these challenges this study suggests that the tea smallholding authority and the government should implement subsidy schemes for replantation and introduce proper mechanisms for the use of fertilizer and other inputs in an affordable manner.

Published: December 2023

The degraded Lake Toba catchment has an impact on the quantity and quality of water in the lake. In addition, the large number of districts and parties involved in managing the Lake Toba catchment makes it hard to integrate management. The purpose of this study is to analyze the roles of the parties in the management of the Lake Toba catchment to provide alternative institutional management. Data covering regulations, activity plans, and issues of coordination and cooperation of the parties were collected using in-depth interviews with key informants from stakeholders in the Lake Toba catchment management and analyzed by qualitative descriptive analysis. Regulations related to the Lake Toba catchment management range from laws to regional regulations. The institutions involved in it include central and regional government agencies and several institutions established for the management of Lake Toba. Even though many programs and activities have been carried out to improve the Lake Toba catchment condition, it has not been successful, because the management has not been integrated among sectors and regions. Therefore, it is necessary to develop a single operational management plan that refers to existing spatial plans and has internalized existing plans, especially watershed management plans, without creating new institutions.

Published: December 2023

The water use conflicts characterize the inefficiency of the lakes as common pool resources (CPR); therefore, consensus-based collaborative management is one of the best alternative solutions. Tropical lakes supporting multipurpose uses such as clean water sources and fisheries for rural people have diverse and unique characteristics which complicate their management. We engaged the Ecosystem-Based Management-Drivers Pressures States Ecosystem Services Responses (EBM-DPSER) framework to analyze the complex system of Lake Singkarak, Indonesia as a study case. The framework is also used to interlink the system with the Ecosystem Services Framework. This link is crucial to conduct economic valuation of the alternate management responses. We classified several management issues based on the perspectives of local stakeholders and researchers. We highlight our findings, that there are significant discrepancies among the focus and perception of local stakeholders and researchers. The differences result in inefficiency of research fund allocation. Current research activities are focused on biophysical aspects, which have different emphasize with stakeholders’ concerns. Therefore, they do not directly answer decision makers’ questions. The constructed framework aids to align these discrepancies by listing prioritized future research to aid solving the disputes and to promote evidence-based decision making in the lake. We expect that the use of the framework can aid the development of scientific-based consensus management and aid future monitoring and evaluation of various management responses.

Published: December 2023

The Ministry of Environment and Forestry Regulation No. 9 of 2021 concerning Social Forestry (SF) is the latest regulation that simplifies the provision of access to the community. The regulation states that SF is a sustainable forest management system implemented in state forest areas or private forests (customary forests) carried out by local communities or customary law communities as the main actors to improve their welfare, environmental balance, and sociocultural dynamics. This study aimed to evaluate the implementation of SF with new regulations. This study was conducted in a pine production forest in Ciamis Regency, West Java Province, Indonesia. Respondents, as many as 88, were members of forest farmer groups with an area of 108 hectares. The SF activities at this location used pine and coffee cropping patterns. Interviews with SF farmers were employed in this study to gather information about the impact of the regulation’s issuance on economic factors and changes in forest access. The study results show that the new regulation increases community access to the forest, including being allowed to plant various plants that were prohibited by the previous regulation. In addition, forest concession rights have a longer duration, from five to 35 years, giving farmers more opportunities to gain economic benefits.

Published: December 2023

Around 1.3 million rural poor individuals reside in Eastern Indonesia, where the government, via the Ministry of Environment and Forestry, aims to enhance the economy by granting access to forest management through social forestry (SF) programs. This study focuses on identifying challenges in implementing SF to alleviate poverty in the region, which remains understudied. Desk research through a literature review of secondary data was conducted to analyze in order to propose recommendations. The primary challenge faced by farmers is the marketing of forest products, due to geographical constraints and limited infrastructure. To address this, a strategy for developing export-oriented forest products is crucial to increase their value and offset high transportation costs. Empowering farmers with market knowledge and skills through training, technical assistance, and access to market information is urgently needed. Successful implementation of SF programs requires collaboration among the government, communities, companies, and other stakeholders. Additionally, improving transportation infrastructure is vital to overcome logistical barriers. Supportive policies from the government, such as simplifying export procedures, tax exemptions, and promotion of international trade, play a crucial role in facilitating the export of forest products. These collective efforts can contribute significantly to poverty alleviation in Eastern Indonesia through SF initiatives.

Directives for commodity development must take into account ideal land use. Land degradation will result from poor land management practices that go beyond the land’s carrying capacity. territory use planning for the growth of certain commodities is part of the direction of commodity development in a territory. The matching technique and the scoring method are the two main approaches that are typically used to evaluate land capabilities. The matching approach compares and matches land features with criteria for the land capacity classes to determine potential in each specific unit using tabular analytic techniques. The criteria for land suitability classes for food crops, namely rice, and horticulture crops, specifically snakefruit, were matched with climate data, data from observations in the field (physical environmental conditions), and data from laboratory study. The value of the Lumajang Regency’s land potential index was calculated and ranged from potential class II (high) to potential class V (extremely low). Potential class IV (low) covers an area of 21,852.20 ha or 12%, class V (very low) area of 883.13 ha, and class II (height) covers an area of 30,318.18 ha or 17% of the entire area of Lumajang Regency. Potential class III (middle) is the biggest class, encompassing 128,090.41 hectares or 70%. The Padang and Sumbersuko sub-districts include the majority of the potential class II regions, while Randuagung, Klakah, Kedungjajang, Gucialit, Senduro, Pasrujambe, Sukodono, and Pasirian sub-districts have part of the remaining class II areas.

Published: December 2023

Omnibus law of the Republic of Indonesia No.11 of 2020 on Job Creation has changed many regulations in the forestry sector. The policy narrative being discussed regarding these changes is Multi-business Forestry (Mb-F). Set against a timber-oriented governance background that has been practiced for almost 5 decades, ambiguity about what objectives and roles of Mb-F are debated. Through the use of content and institutional analysis, this study aims to define its. Content is sourced from 30 national news and journals as well as audio data from in-depth interviews with 36 experts transferred to text form. Text data was processed using NVivo software after highlighting, condensing, coding, categorizing, and theming. This process defines the objectives, which are then further analysed to define the alliances and roles using Mactor software. This research found three main themes, namely performance & governance, forest land-use & productivity, and social-economy impact & environmental concern. These three themes are rooted in 10 objectives, namely land-use, timber, food, NTFP, employment, state revenue, corporate benefit, biodiversity, climate change, and soil/water conservation. The key stakeholders that have the highest influence and independence in implementing Mb-F are the Ministry of Environment and Forestry, which is relayed by Experts, Regions Forestry, Environmental, and Food & Horticulture Services, as well as the Business World. Employment is the objective that gets the highest weighting, and timber gets lowest. This indicates that the Mb-F Policy narrative will encourage a change in the orientation of Indonesia’s forest governance harshly.

Published: December 2023

The Indonesian government has implemented various policies to meet the population’s need to raise staple food. Global food crises and malnutrition issues arise from several factors including population growth, uncontrolled conversion of rice fields, shifting consumption patterns, and climate change. Therefore, efforts to maintain and increase domestic rice production have become crucial to reduce potential food vulnerabilities and dependence on other countries for food. This study aims to analyze the dynamics of domestic rice sufficiency in the Banyumas Regency, analyze key related variables, and formulate policies to maintain it. The research methods used were visual image interpretation, building dynamic models, and conducting prospective analysis using the MICMAC method. The results show that domestic rice sufficiency is decreasing, resulting in a widening gap between the population’s rice needs and the domestic rice supply. The domestic rice supply in the study area can meet the rice needs of the local population by 2025, and in 2026, a deficit will begin to occur. Policies that can be implemented include increasing the planting index, improving rice productivity, food diversification, and implementing regulations to protect the rice fields. Critical variables in its implementation include the Regent’s Regulation on Rice Field Protection, detailed spatial information on rice fields, irrigation water availability, and the active role of farmer groups.

Published: December 2023

As a class of broad-spectrum antibiotics, tetracyclines find extensive use in human, veterinary, and aquacultural applications. Releasing tetracycline in the form of parent or derivative compounds into the aquatic environment is extremely dangerous to human health. This study investigates the ability of silica (SiO2) extracted from Beureunut beach sand to remove tetracycline in an aqueous solution by combining adsorption and Fenton-like oxidation. The beach sand was used as a precursor, and it was reacted with a sodium hydroxide solution at 80 °C before being precipitated with sulfuric acid and dried. The extraction yielded 9.22 g of silica, which was then further characterized using Fourier transform infrared (FT-IR) spectroscopy. Prior to the adsorption test, the stability of tetracycline solution was evaluated at two different temperatures (11 °C and 30 °C). The findings of a 6-day stability test performed in water showed that tetracycline was more stable at 11 °C than at 30 °C. The adsorption capacity of silica was found to be 1.68 mg/g (17.00%) at 50 mg/L tetracycline concentration after 3 hours of contact time. Meanwhile, the adsorption method combined with the Fenton-like process increased the percentage of tetracycline removal from 17.00% to 56.32%. In conclusion, combining adsorption and Fenton-like processes provides an option for greatly increasing the ability of beach sand-based silica as a potential adsorbent to remove tetracyclines from water.

Published: December 2023

The high population of Central Java Province has become a factor triggering the dynamics of land cover change and regional development. Uncontrolled urban expansion and development threatens sustainability. This study aims to identify the types and patterns of land cover change, the level of regional development, the index of sustainable development in environmental, social, and economic dimensions, and the typology of regencies/cities based on the index of sustainable development. This research was conducted in Central Java Province from January to April 2023 using land cover data, village potential data, provincial statistics, and administrative maps. Land-cover changes were identified using overlay analysis in QGIS. The level of regional development was determined using the scalogram. The index of sustainable development was constructed using factor analysis, while the regional typology was identified using cluster analysis. The results showed a dynamic change in forest cover, with a significant decrease from approximately 1 million hectares to 550,000 ha from 2014 to 2019. Agricultural land and built-up areas increased by 312,000 ha and 164,000 ha, respectively. A scalogram analysis indicated an improvement in the regional development index. Sustainability analysis reveals that the sustainability index in the economic dimension is lower than that in the social and environmental dimensions. The cluster analysis indexes that approximately 60.31% of the areas had a low sustainability index. All urban areas have a high sustainability index in the economic and social dimensions, otherwise in the environmental dimension.

Landslides in geothermal areas are one of the environmental challenges that are attributed to their volcanic and hydrothermal systems. However, the inventory of landslides in geothermal areas remains considerably limited. This may implicate pitfalls, where characterisation of historical events is an essential practice in disaster risk management. Accordingly, this exploratory study aims to characterise landslide events in 19 geothermal areas with historical landslides. This introductory study was sourced from electronic news, scientific publications, and authoritative institutions. The collected records were cross-examined and integrated into comparable attributes. The resulting characteristics display the physical features, environmental factors, and mitigation measures as follows: (1) landslides commonly occur in small to extremely large volumes. However, serious tolls may be caused even by small-to modest-sized landslides. (2) Landslides may not be preceded by triggering factors but by their gradually weakened environment. (3) Although there are scattered sources and unclear information related to underreported landslides and understudied mitigation, respective authorities conduct rapid measures following the landslide event. Correspondingly, it is highly recommended to further improve and establish a landslide inventory database in geothermal areas that constitutes a more comprehensive overview for better risk management.

Published: December 2023

The most widely produced agricultural commodities in Indonesia are oil palm and paddy crops, which contribute the most to national income in the agricultural sector. On the other hand, in 2020, the agricultural sector contributed 9% to national greenhouse gas (GHG) emissions. This study aims to determine the effect of agricultural crop production, namely oil palm and paddy on GHG emissions in Indonesia’s agricultural sector from 2000-2020. Data for the study were obtained from the Directorate General of Climate Change, the Ministry of Environment and Forestry and BPS-Statistics Indonesia. The GHG effect of agricultural crop production were analyzed using multiple linear regression. The findings showed that the production of oil palm and paddy crops significantly affects the agricultural sector’s GHG emissions. Oil palm and paddy production have a significant level of 5% with a regression coefficients of 0.4958 and 0.0003, respectively. From the findings, it can be implied that an increase in oil palm and paddy production will raise Indonesia’s agricultural sector GHG emissions. The government can draw up regulations related to (1) protecting forest areas and peatlands close to community residential areas so that land conversion does not occur in oil palm plantations and (2) a sustainable agricultural system to increase paddy productivity, hoping that the agricultural sector’s GHG emissions will decrease.

Published: December 2023

Emissions from transportation activities can cause GHG effects, which cause an increase in city air temperature. The city of Bogor is working on processing BisKita as mass transportation, which is considered more environmentally friendly than public transportation (Angkot). This study aimed to analyze the basic conditions of climate-related transport emissions before and after BisKita and formulate good practice options for reducing emissions. The research was conducted in Bogor, West Java Province, focusing on public transportation and BisKita, which had not yet operated on the K3 (Ciparigi – Ciawi) and K4 lines (Bubulak – Sukasari Bus Terminal via Surya Kencana). The resulting emission value is obtained by calculating the vehicle emission value with the factors of route length, number of fleets, and total fuel consumption. The formulation of good practice options is generated for implementing low-emission transportation that is more environmentally friendly by analyzing various transportation policy literature that originates from literature studies. The analysis showed that angkot emissions could be reduced by 18.6% on the K3 route and by 14.8% on the K4 route as a reduction strategy (three angkot:1 bus) with BisKita as mass transportation. Bogor can implement various green transportation transitions and operational plans from other countries and cities in Indonesia.

Flash floods are catastrophic phenomena known for their rapid and unpredictable occurrence. They frequently display precursory indicators, which, when comprehensively studied, serve as vital clues for effectively anticipating and preparing for these events, thus reducing their adverse effects. This study aimed to investigate the key trigger factors contributing to a flash flood event in the upper Ciliwung Watershed in January 2021. Data collection involved various parameters, including morphology, precipitation patterns, land use, hydrological characteristics, and soil conditions collected from the affected area. These data were subsequently analyzed using geospatial methods and enriched with information from local community members. The analysis found multiple contributing factors to flash floods, including high soil moisture content due to prolonged precipitation, geological characteristics, and steep topography. The local community recognized landslides, creating a natural dam about a month before the flash flood. Unfortunately, inadequate measures were taken to address the flood due to limited understanding and resources. The heavy rainfall before the flash flood put immense pressure on the natural dam, causing it to fail and carry debris downstream. The steep banks of the surrounding river worsened the situation. The study’s findings can provide valuable insights for local authorities, leading to better resource allocation.

Despite previous reports of contamination from domestic waste, agricultural runoff, and fertilizers, shallow groundwater (GW) within Bandung Regency remains a clean water source. Nitrogen is one of the most common contaminants identified in the region. This study aims to assess nitrogen concentrations and determine the groundwater pollution index (GWPI) caused by nitrogen. The GWPI categorizes water as excellent water (GWPI <0.5), good (0.5< GWPI <0.75), moderately polluted (0.75< GWPI <1), and highly polluted (GWPI >1). Twenty-seven GW samples were collected during the wet season in October 2022, and physicochemical parameters were analyzed, including pH, dissolved oxygen, GW temperature, electrical conductivity, total dissolved solids, oxidation-reduction potential, dissolved iron and manganese, ammonium, nitrate, and nitrite. According to the analysis, there was a significant variation in the dissolved inorganic nitrogen (DIN), with 12 samples dominated by ammonium and 15 samples dominated by nitrate. The GWPI calculation ranges from 0.96 to 3.52, indicating that 33% of the samples exhibit excellent water quality, 19% show good water quality, 22% demonstrate moderately polluted water, and 26% demonstrate highly polluted water. Based on the spatial distribution analysis, it was found that the settlement exhibited the most substantial levels of GW pollution due to DIN.
Forest fires social and climate change in Cyprus

Published: December 2023

Forest fires and wildfires are increasing in many regions of the world and give the big impact on the environment, local economies, livelihoods, and societies. Cyprus is an island member of the European Union in the south-eastern Mediterranean and it is severely affected by wild fires. The aim of this paper is to review the pertinent, recent literature (which although not exhaustive, identifies the main contributing factors) mostly in the Mediterranean region and to identify the variables that affect the rise in the number and intensity of forest fires, wildfires and how these variables are affecting Cyprus. This research was conducted by using statistical data made by the Cyprus Statistical Service. By compiling the data of climatology, demography, agricultural production, and forest fire incidents, some results were found. The increased forest fires were caused by the rise of the average annual mean temperature in the period of 1990-2021, the change in social conditions and agricultural land use with the urbanization of people living around the forest areas, and the conservative policies adopted by successive administrations with reference to forest management and conservation.
Studies on flood disaster causes in DKI Jakarta Province

Published: December 2023

Flood is a disaster that occurs in almost regions of Indonesia, including DKI Jakarta province. From 2016 to 2020, there were more than 50 flood events in DKI Jakarta province. Several previous studies mentioned various factors that could cause flooding in DKI Jakarta province, including rainfall intensity, sea surface level, land surface level, and land use changes. This study aims to analyze and find out the main factors that cause floods in DKI Jakarta province. The data obtained from processing the interpretation of satellite imagery and literature review were then analyzed using a quantitative descriptive method with the Pearson correlation test to determine the coefficient value and the level of correlation/relationship between variables. The results showed that the rainfall intensity has a value of 0.968, the land use changes factor is 0.138, the land surface level factor is 0.095, and the sea surface level factor has a value of 0.051. Rainfall intensity has the highest value, with a strong correlation/relatedness to flood events. Land use changes, land surface level, and sea level have a shallow correlation/relationship to flood events. Thus, the rainfall intensity is the main factor causing flooding in DKI Jakarta province.
Delonix regia as a climate bio-indicator: The effect of climate change on flowering time in Kupang, East Nusa Tenggara
Authors: Fanggidae Y R , Ramadhani F
Published: December 2023

The study of climate bio-indicators, such as the flowering time of plants, can provide valuable insights into the effects of climate change on the environment. In this study, we investigated the impact of climate change on the flowering time of Delonix regia in Kupang, East Nusa Tenggara. Delonix regia trees at 50 points were observed, and their flowering time was determined in monthly time series between 2013 and 2022 using the Normalized Difference Vegetation Index (NDVI) technique with Landsat 8 satellite imagery. The NDVI criteria for determining flowering were verified through real-time observations during the flowering season in 2021 – 2022 and confirmed using Google Earth imagery. The study’s findings indicate that Delonix regia trees in Kupang previously mass-flowered (> 75% of the population with 65 – 100% closure of the canopy area) once a year in November – December over the past decade, but the flowering time is now changing. Some observed trees in 2021 and 2022 flower twice a year, in April – May and November – December, causing flowering not to close the canopy as in previous years fully. Changes in temperature and rainfall affect the timing of flowering. Increased rain in February-March-April 2021 and 2022 (> 65 mm from the climatology 1990 – 2020) and warmer annual average temperature conditions are thought to trigger flowering initiation, which suggests that climate change significantly impacts the local environment. Our results demonstrate the potential of Delonix regia can be one of the climate bio-indicators and emphasize the importance of monitoring the flowering times of plants.
