Elephant Grass Cultivar BRS Capiaçu as Sustainable Biomass for Energy Generation in the Amazon Biome of the Mato Grosso State

Sustainable biomasses are vital to ensure preservation of the Amazon biome within the Mato Grosso State whilst enabling energy generation for the region and its population. Here, the potential of the elephant grass cultivar BRS Capiaçu as an alternative to replace native forest wood as biomass for energy generation is investigated, considering the whole process from plant cultivation to biomass characterisation in terms of productivity of green and dry mass per hectare; density, moisture, ash, volatile and fixed carbon content, as well as higher heating value (HHV). MANOVA indicates that the effects of plant parts and age on density and proximate analysis parameters are influenced by the plant parts and age interaction, whereas HHV can be considered similar between them. The cultivar BRS Capiaçu showed suitable energetic values (17,922 < HHV < 18,918 kJ.kg−1) compared to that of native Amazon wood. Energetic results combined with cultivation outputs of high productivity (dry mass production of 44.1 tonnes.ha−1 at 180 days) with a short cutting interval (3 months), adaptation to the region’s climate and soil, and the possibility of cultivation in areas currently consolidated for agriculture demonstrate the potential of BRS Capiaçu as biomass to reduce native wood usage and deforestation rates.

The Bionomic Equilibrium Model for Balancing Forest Conservation and Economic Growth: Empirical Evidence from Indonesia

Abstract: The objective of this study is to balance forest conservation with economic growth while accounting for the rate of deforestation. The methodology employed in this research utilizes a mathematical modeling approach, specifically adopting the logistic model to represent forest growth rates. In addition, numerical analysis is applied to illustrate the impact of economic activities on forest areas. The data used in the study consist of deforestation rates in Indonesia from 2000 to 2021. The findings indicate that the rate of economic activity in forested areas is directly proportional to the reduction in forest area. If the rate of deforestation due to economic activity approaches the forest growth rate, the likelihood of forest area reduction increases, and forest depletion will occur if the two rates become equal. To resolve the dilemma between forest conservation and economic growth, this study proposes a solution consisting of three key steps: (1) establishing a minimum forest area that is strictly protected from economic exploitation; (2) setting the ratio between forest growth rates and economic activity rates as a primary foundation for ensuring sustainable forest conservation and economic development; and (3) calculating environmental costs, such as reforestation, based on the proportional relationship between deforestation rates and forest growth rates.

Co-Management Effects on Forest Restoration in Protected Areas of Bangladesh: A Remote Sensing and GIS-Based Analysis

Co-management is a promising forest governance strategy that integrates local communities’ traditional rights and forest dependencies while aiming to improve forest cover and ecosystem health. Bangladesh, facing high deforestation rates and limited per capita forest area, has implemented co-management initiatives since 2003 to restore forest cover and support the livelihoods of forest-dependent communities. While the socio-economic impacts of co-management are well studied, its effects on forest cover remain underexplored. This study addresses that gap by using three common spectral vegetation indices (NDVI, EVI, and MSAVI), calculated from Landsat 7 data, to analyze forest cover changes in five major protected areas under co-management. The results indicated that dense forest cover (41–71%) was initially prevalent in these areas, but a significant decline occurred between 2004 and 2015, with slope values ranging from −3.7 to −0.96. In contrast, the non-co-managed control site exhibited a much smaller decline (slope: −0.48 to −0.62) across all indices. Notable increases in agricultural land and forest–agriculture mosaics were also observed in the protected areas under co-management. Global Forest Watch data further confirmed substantial forest cover loss, particularly in CWS (158.77 ha) and SNP (0.49 ha). These findings highlight the need to reassess co-management strategies to address ongoing forest degradation.

All Deforestation Matters: Deforestation Alert System for the Caatinga Biome in South America’s Tropical Dry Forest

This study provides a comprehensive overview of Phase I of the deforestation dryland alert system. It focuses on its operation and outcomes from 2020 to 2022 in the Caatinga biome, a unique Brazilian dryland ecosystem. The primary objectives were to analyze deforestation dynamics, identify areas with highest deforestation rates, and determine regions that require prioritization for anti-deforestation efforts and conservation actions. The research methodology involved utilizing remote sensing data, including Landsat imagery, processed through the Google Earth Engine platform. The data were analyzed using spectral unmixing, adjusted Normalized Difference Fraction Index, and harmonic time series models to generate monthly deforestation alerts. The findings reveal a significant increase in deforestation alerts and deforested areas over the study period, with a 148% rise in alerts from 2020 to 2022. The Caatinga biome was identified as the second highest in detected deforestation alerts in Brazil in 2022, accounting for 18.4% of total alerts. Hexagonal assessments illustrate diverse vegetation cover and alert distribution, enabling targeted conservation efforts. The Bivariate Choropleth Map demonstrates the nuanced relationship between alert and vegetation cover, guiding prioritization for deforestation control and native vegetation restoration. The analysis also highlighted the spatial heterogeneity of deforestation, with most deforestation events occurring in small patches, averaging 10.9 ha. The study concludes that while the dryland alert system (SAD-Caatinga—Phase I) has effectively detected deforestation, ongoing challenges such as cloud cover, seasonality, and more frequent and precise monitoring persist. The implementation of DDAS plays a critical role in sustainable forestry by enabling the prompt detection of deforestation, which supports targeted interventions, helps contain the process, and provides decision makers with early insights to distinguish between legal and illegal practices. These capabilities inform decision-making processes and promote sustainable forest management in dryland ecosystems. Future improvements, including using higher-resolution imagery and artificial intelligence for validation, are essential to detect smaller deforestation alerts, reduce manual efforts, and support sustainable dryland management in the Caatinga biome.

Evaluating the barriers to adoption of improved biomass cookstoves in Benue state, Nigeria

The prevalent use of inefficient traditional stoves for biomass cooking energy in Nigeria contributes to high rates of biomass consumption, deforestation, and harmful pollutant emissions. This study aimed to assess the constraints hindering the adoption of improved biomass cookstoves (IBCS) in Benue State, Nigeria. Data were randomly collected from 135 households and analyzed using descriptive (frequency, mean and percentage) as well as inferential statistics (binary probit regression). Findings revealed that 88% of households rely on fuelwood for cooking, with approximately 35% still using traditional stoves. However, 46% of households have adopted IBCS and recognized its advantages, including improved cooking speed, fuel economy, time savings in fuelwood collection, cost savings, and reduced smoke emissions. Additionally, various factors such as age, household size, access to credit, location, distance to market, membership of women's associations, fuelwood collection distance, and fuelwood sources were identified as constraints to IBCS adoption. To promote IBCS adoption, we recommend that development planners and extension officers raise awareness among households and provide them credit incentives through government and NGO support. This research significantly contributes to pertinent knowledge by shedding light on the challenges and opportunities associated with IBCS adoption in Nigeria, thereby informing policy and development initiatives in the country.

Reptile Diversity Patterns Under Climate and Land Use Change Scenarios in a Subtropical Montane Landscape in Mexico

ABSTRACTAimMountainous regions are rich in reptile biodiversity but face threats from climate and land use changes. Understanding how these factors affect reptile diversity in these regions can highlight key conservation hotspots that require effective conservation actions. Here, we explored reptile taxonomic and functional diversity patterns along the Sierra Madre del Sur region in southeast Mexico, and potential changes in future years caused by different climate and land use change scenarios.LocationSierra Madre del Sur, México.TaxonReptiles.MethodsWe used species distribution models and information on species traits to estimate taxonomic and functional diversity throughout the Sierra Madre del Sur (SMS) region under current and future climate and land use change scenarios.ResultsGreater taxonomic and functional diversity was observed in both temperate and tropical forests. Taxonomic diversity was higher in more drier areas at high elevations while higher functional diversity was observed in wetter areas at intermediate‐to‐high elevations. Lower diversity for both dimensions was associated with anthropic land uses. In future scenarios, both dimensions of diversity are expected to increase in temperate forest in highlands of central Oaxaca and decrease in the southcentral portion of the SMS, particularly for the worst scenarios due to increased deforestation rates.Main ConclusionsHigher taxonomic diversity in more drier areas at high elevations could be due to historical and evolutionary factors, while higher functional diversity in wetter areas at intermediate‐to‐high elevations may be explained by a higher environmental heterogeneity in forests within these conditions. Larger diversity losses in the southcentral portion of the SMS are probably due to larger predicted deforestation rates in those areas. Our results are valuable not just for informing conservation actions, such as the creation of protected natural areas but also to understand the underlying processes behind the patterns of reptile diversity.

Spatial Analysis of Regional Planning Related to Moratorium Right to Cultivate (Plantation) in Indonesia

Indonesia is a country that is blessed by Allah Swt with a very large expanse of space and territory and is located on the equator surrounded by the sea. This is a natural resource that is very rarely owned by other countries, where the sun shines every year with high humidity. These resources are controlled by the state and used as much as possible for the welfare of the community. One of the related natural resources is plants that can grow well in the area. Oil palm is a plant originating from West Africa that is very suitable for growing in the equatorial area. Currently, Indonesia is the largest producer of palm oil in the world. The greatest utilization of this blessing are for the welfare of the community and based on sustainable Regional Spatial Planning. On its implementation the Regional Spatial Planning has been divided according to its function and sustainability. This condition is contrary to the current government policy, where the government has implemented a moratorium policy on new business use rights for the Plantation sector. The regulation was Presidential Instruction (Inpres) Number 8 of 2018. The purpose of the Moratorium is to control the deforestation of Primary Forests and also improve the Governance of Oil Palm Plantations. In its implementation, there are indeed successes and weaknesses. Successes are mainly in holding back the rate of deforestation or forest encroachment. The weakness is that in terms of Regional Spatial Planning, there should still be many areas that can be used for developing plantation land, especially unproductive and non-forest areas. So that the ideals of improving the welfare of the community can be truly realized.

Long-term changes of mangrove distribution and its response to anthropogenic impacts in the Vietnamese Southern Coastal Region

Human activities related to land use and land cover (LULC) conversion have been the primary factor driving changes to mangrove distribution over recent decades. In order to quantify the anthropogenic influences associated with LULC changes on mangroves in the Vietnamese Southern Coast (VSC), we investigated the variations and trends in mangrove distribution between 1988 and 2023. We used a time-series of Landsat spectral indices from Google Earth Engine and applied hot spot analysis and machine learning algorithms to analyse mangrove variations and LULC classification, respectively. Our findings revealed that over the past 36 years, approximately half of the mangrove area has been lost due to LULC conversions. The most significant losses in mangrove cover occurred during the 1998–2011 period, with a decline of 46.79% in total area (an average of 3.6% per annum). The rate of mangrove deforestation more than halved to 17.49% (1.5% per annum) in the period between from 2011 to 2023. We attribute the reduction in mangrove loss to conservation efforts and natural regeneration processes. The emerging hot spot analysis indicated that the most significant restoration of new mangrove areas occurred between 1988 and 1998, totalling 1795 ha (1.4%), while the highest rate of mangrove deforestation was observed between 1998 and 2011, amounting to 2249 ha (2.0%). The primary causes of these variations in mangrove distribution were the conversion of mangrove areas to shrimp farming (38.91%), followed by other agricultural land use (5.82%) and the expansion of impervious surfaces (3.34%). In contrast, a result of enhanced conservation efforts and natural regeneration was associated with a 17.91% of mangrove area gain in the 2011–2023 period. Despite the regeneration potential of mangroves, our study highlighted the ongoing need to manage and protect mangrove forests to facilitate their expansion in the VSC. The analytical approach adopted in this study is applicable to other coastal areas when assessing changes in mangroves and land use practices.

Deforestation and Children: Consequences for Paediatric Malaria and Educational Attainment in Indonesia

This study examines the effect of forest loss on child health and educational outcomes in Indonesia, a country that has experienced one of the highest deforestation rates in the world. In line with the findings in the medical and biological literature that deforestation can encourage the breeding of malaria-carrying mosquitoes through changes in local ecosystems, our estimation results show that deforestation significantly increases child fever but not other infectious diseases, implying an increased incidence of malaria infection due to deforestation. In addition, the results from the education analysis show that children exposed to larger-scale deforestation in early childhood are afterwards more likely to fall behind academically in terms of years of education. Various robustness checks suggest that these adverse health and educational effects are driven by forest loss but not by other possible preexisting trends or confounders.

Revisiting the Narrative of Deforestation in Central and Southern Mainland Early Modern Portugal as a ‘Ruined Landscape’: The Case of Shipbuilding in Lisbon

AbstractScholars have largely blamed shipbuilding for maritime expansion for being the main driver of deforestation in early modern Portugal. This article sets out to revisit the origins and reproduction of this narrative by analysing three interconnected elements in a case study of Lisbon's shipyards. Firstly, it studies the claims of forestry policies from the 1400s to the mid‐1600s. Secondly, it addresses Portuguese writers and foresters of the nineteenth century. Thirdly, it surveys the calculations of deforestation rates provided by Portuguese and foreign authors and foresters. Three main conclusions can be drawn: (1) scholars’ arguments that shipbuilding was chiefly responsible for deforestation are based on the claims set out in Portuguese forestry policies, (2) nineteenth‐century authors and writers stated multiple causes to explain the significant deforestation in early modern Portugal, and (3) it is very likely that the high deforestation rates that nineteenth‐ and early twentieth‐century authors reported are partially due to shifts in the meaning of ‘woodland’.

Conservation and Avoided Deforestation: Evidence from Protected Areas of Tanzania

Tanzania dedicates a substantial proportion (38%) of its territory to conservation, with a large number of Protected Areas (PAs) managed under various regimes. Nevertheless, the country still experiences high rates of deforestation, which threaten the ecological integrity and socio-economic benefits of its forests. We utilized the Global Forest Change Dataset (2012–2022) and implemented a Propensity Score Matching (PSM) approach followed by a series of binomial logit regression modeling. Our objectives were to evaluate (1) the likelihood of PAs in avoiding deforestation compared with unprotected forest landscapes, (2) the variability in effectiveness among the different PA management regimes in avoiding deforestation, (3) evidence of leakage, defined here as the displacement of deforestation beyond PA boundaries as a result of protection inside PAs. Our findings reveal that, despite ongoing deforestation within and outside of PAs, conservation efforts are, on average, three times more likely to avoid deforestation compared with unprotected landscapes. However, the effectiveness of avoiding deforestation significantly varies among the different management regimes. National Parks and Game Reserves are nearly ten times more successful in avoiding deforestation, likely because of the stringent set of regulations and availability of resources for implementation. Conversely, Nature Forest Reserves, Game Controlled Areas, and Forest Reserves are, on average, only twice as likely to avoid deforestation, indicating substantial room for improvement. We found little evidence of the overall leakage as a consequence of protection. These results highlight the mixed success of Tanzania’s conservation efforts, suggesting opportunities to enhance the effectiveness of many less protected PAs. We conclude by proposing potential strategic pathways to enhance further the climate and ecosystem benefits of conservation in Tanzania.

Charting the future of high forest low deforestation jurisdictions

High forest low deforestation jurisdictions (HFLDs) contain many of the world's last intact forests with historically low deforestation. Since carbon financing typically uses historical deforestation rates as baselines, HFLDs facing the prospect of future threats may receive insufficient incentives to be protected. We found that from 2002 to 2020, HFLDs (n = 310) experienced 44% higher deforestation rates than their historical baselines, and 60 HFLDs underwent periods of high deforestation (deforestation rate > 0.501%) at 0.983 ± 0.649% (mean ± SD)-a rate 7.5 times higher than the 10-y historical baseline of all HFLDs. For HFLDs to receive sufficient carbon finance requires baselines that can better reflect future deforestation trajectories of HFLDs. Using an empirical multifactorial model, we show that most contemporary HFLDs are expected to undergo higher deforestation from 2020 to 2038 than their historical baselines, with 72 HFLDs likely (>66% probability) to undergo high deforestation. Over the next 18 y, HFLDs are expected to lose 2.16 Mha y-1 of forests corresponding to 585 ± 74 MtCO2e y-1 (mean ± SE) of emissions. Efforts to protect HFLD forests from future threats will be crucial. In particular, improving baselining methods is key to ensuring that sufficient financing can flow to HFLDs to prevent deforestation.

Evaluating mangrove community forestry outcomes: a mixed synthetic control and field-based approach

Abstract Contemporary evaluations of outcomes in human-managed systems have been constrained by a lack of counterfactual analysis. Community forestry (CF), a widely adopted strategy to achieve both conservation and management in coupled human-environment systems, is no exception, and counterfactual analysis would greatly enhance CF research. We used a mixed method approach incorporating quantification of deforestation and forest regrowth rates, synthetic control analysis, and focus groups discussions to evaluate mangrove CF outcomes in the Ayeyarwady Delta, Myanmar, from to 1990–2021. CF resulted in an overall increase in net forest gain and reduction in net forest loss across sites. More than two-thirds of CF sites had superior outcomes relative to synthetic controls for at least one metric (deforestation or forest regrowth); however, CF tended to perform better for only one outcome while avoiding underperformance in the other. The annual rate of forest regrowth in CFs accelerated beginning three years prior to certification and peaked two years after certification, likely related to pre-certification engagement with the Forest Department or non-government organizations. Moreover, control sites near CFs experienced more rapid forest regrowth than controls further from CFs, suggesting spillover effects. The predominant challenge facing successful CF management was illegal extraction and overharvesting, and poor performing CFs experienced a complex array of challenges facing forest regrowth, likely related to the private nature of individual land claims within the CFs. Most supporting factors for CF were related to community management capacity, strongly indicating a need for extended close engagement with competent government and non-government actors to develop long-term management and governance capacities, which are sustainably funded. Our mixed-method approach can be replicated in other human-managed systems to evaluate the biophysical impacts of policies and gain insights into the underlying drivers of outcomes.

The role of blue carbon in reversing mangrove degradation trends in Mexico

Blue carbon projects in Mexico, or the conservation and restoration of tidal wetlands such as mangroves, can reduce carbon emissions while providing additional ecosystem services for local communities. However, at the national scale, the “additionality” (or added project benefits) of mangrove projects is difficult to demonstrate due to recent slowing deforestation rates. While deforestation in Mexico decelerates, mangrove degradation is pervasive and spreading. Reversing or ending mangrove degradation could rapidly protect the carbon stored and reduce future greenhouse gas emissions. Here, we explore Mexico's conceptual, methodological, and social challenges for tackling mangrove degradation and achieving successful rehabilitation outcomes. We identified that the first challenge is establishing an accepted national definition of mangrove degradation compatible with earlier methods and measurable with spatial imaging techniques. Other challenges are aligning on-ground monitoring with remotely sensed degradation assessments, including reference sites, harmonizing national programs with global datasets, and standardizing information to meet blue carbon project accreditation requirements. Finally, knowledge sharing, collaboration, and reporting failed and successful projects are crucial for fast-forwarding reliable and verifiable blue carbon projects that effectively contribute to reversing mangrove degradation trends in Mexico.

Impactos das Atividades Agrícolas em Área de Amazônia Legal: Análise Espaço-Temporal das Mudanças de Cobertura do Solo entre 1985 e 2022

The Brazilian Forest Code stipulates the conservation of 80% of forested areas on rural properties as legal reserves. However, in recent decades, the expansion of agricultural areas has resulted in significant alterations to land use and cover. The objective of this investigation is to analyze the changes and transformations that have occurred in land use and coverage in the city of Sinop-MT, which is derived from the occupation of the Brazilian Legal Amazon. The spatio-temporal change between the years 1985 and 2022 was investigated. The methodology employed to obtain the maps was through the MapBiomas Platform. Socioeconomic reports were collected from the Brazilian Institute of Geography and Statistics (IBGE) database. The results indicated that agriculture in the region advanced significantly between 1995 and 2005, corresponding to the economic boom under the Real Plan. This period saw a surge in territorial expansion in the northern region of Mato Grosso, which was encouraged by the federal government. This expansion led to high rates of deforestation. Nevertheless, in 2004, monitoring programs were initiated with the objective of containing deforestation in the Legal Amazon. This resulted in the cessation of agricultural expansion between the years 2005 and 2022.

An environmental Kuznets curve for global forests: An application of the mi-lasso estimator

In this study, we employ a Moran's i based Lasso (Mi-Lasso) methodology to address the spatial dependence of an unspecified functional form, investigating the association between a country's economic growth and the rate of deforestation. Our aim is to explore the existence of a forestry environmental Kuznets curve (EKC). Our approach to handling spatial dependence overcomes limitations identified in existing EKC literature. We estimate a series of cross-sectional data models spanning the period from 1990 to 2020 for 146 countries. Our findings indicate a non-linear relationship, revealing a change peak rate of deforestation over time. Additionally, we observe that the income threshold at which the deforestation rate begins to decrease changes over time with differences observed between model specifications. Crucially, our results highlight that failing to account for spatial dependence leads to a significant absolute upward bias in ordinary least squares (OLS) estimates of income and worse model fit.

Protected area creation and its limited effect on deforestation: Insights from the Kiziba-Baluba hunting domain (DR Congo)

The study examines the spatiotemporal dynamics of landscape anthropization in the Kiziba-Baluba Hunting Domain (KBHD), near Lubumbashi in southeastern Democratic Republic of Congo, facing increasing human threats. It assesses these dynamics from 1989 to 2023 using remote sensing, Geographic Information Systems (GIS), and landscape ecology principles. The results reveal a significant decrease in forest cover, declining from 70.33 % in 1989 to 26.22 % in 2023, with an annual deforestation rate of -1.84 %. This deforestation has led to the expansion of savannas (63.93 %), agriculture (5.76 %), and built-up and bare soil (0.93 %) through patch creation and aggregation. The level of landscape disturbance has increased sixfold over 34 years, from 0.42 in 1989 to 2.81 in 2023. The reduction in the size of the largest forest patch and increased spatial isolation show rising fragmentation and dissection, often followed by the attrition of residual patches. These findings highlight the inefficiency of current conservation measures in KBHD, indicating a need for restructuring management, redefining protected area boundaries, developing a suitable management plan, implementing reforestation programs, strengthening enforcement of environmental laws, and actively involving local communities.

Uncontrolled deforestation and population growth threaten a tropical island's water and land resources in only 10 years.

Rapid demographic growth in tropical islands can exacerbate conflicts and pressures on natural resources, as illustrated by the French island of Mayotte where resources are limited. In only 10 years, uncontrolled migration and population growth (+80% of population between 2002 and 2021) have led to a pronounced 3600% increase in deforestation rates (2010-2014) and an intensification of agricultural practices, escalating conflicts over limited land, water, and biodiversity resources. Implementing an original multi-proxy approach to sediment cores, our study reveals a staggering 300% acceleration in erosion during the first wave of migration (2011-2015), followed by a further 190% increase (2019-2021) under sustained migratory and demographic pressures. Sedimentary DNA analysis provided insights into increased connectivity and community changes. By 2050, the population of this region will increase by 74 and 103%, in Comoros and Madagascar islands, respectively. Urgent conservation measures are needed to avoid major socio-environmental crises and to protect resources for future generations.

Fire is associated with forest degradation and economic land concessions, but not land conversion in the rapidly transforming Cambodian landscape

Abstract Cambodia is beset by high deforestation rates and fire frequencies. From 2001–2020, forest cover declined by 34%, and cropland and rubber expanded by 31,401 km2 and 4,530 km2, respectively; meanwhile nearly 8.7 million fires burned 41.6% of the land. Fires may be associated with deliberate land change, stable land management systems, and unplanned forest degradation. We integrated annual land cover and monthly burned area data from 2001–2020 to test three hypotheses. First, if fire is used during land conversion, there would be a detectable pulse in fire activity in the year immediately prior to, and the year of land cover change. Our temporal analysis found statistically elevated burn rates in five of 16 transition tests, however, they were typically <1% outside the predicted range, indicating no practical significance in the association of fire with land cover change. Second, fire prevalence would be lower in land managed for conservation or agricultural production than unclassified or unmanaged land. persistent forest and shrubland burned at significantly higher rates than expected, cropland burned significantly less, burning was almost absent from rubber plantations, and forests in protected areas (PAs) exhibited lower total burn percentages than unclassified land or industrial economic land concessions (ELCs), thus supporting the fire-land management hypothesis. However, total burned area in ELCs was greater than unclassified land for several persistent land cover classes, suggesting that local landowners may prevent fire in commercially valuable private agricultural land, but there may be no such prevention measures in industrial ELCs. Anti-fire policy enforcement in ELCs should be enhanced. Third, forests that converted into (degraded) shrublands would experience increasing fire frequency in the years leading up to transition, a hypothesis we found strong support for through our temporal analysis. Cambodia’s 2013 Law on Fire Prevention and Fire Fighting deputizes the public to enforce its provision, however given that the vast majority of fires occur in persistent forest in state-owned land, collective action problems are likely to hinder its effective implementation.

PRELIMINARY MONITORING OF WATER QUALITY AT BANTURUNG VILLAGE, BUKIT BATU DISTRICT, PALANGKA RAYA CITY

Water is a vital necessity for human and living things in general. It is undeniable that the decline in water quality today is the result of human activities that overexploit the environment. People's lifestyles that pay less attention to environmental aspects such as throwing garbage out of place, disposing of hazardous waste, and changing the function of forest areas that can increase the potential for erosion and often cause sedimentation at the bottom of the waters have a negative impact both directly and indirectly on the natural environment, especially water sources. High rate of forest degradation and deforestation has a significant impact on changes and decreases in water quality. In this study, water quality monitoring was conducted using several parameters as an initial step to understand the condition at the Dam and Clean Water Facility in Banturung Village, Bukit Batu District, Palangka Raya City. The results obtained from the analyzed parameters include odorless, pH 5.9, turbidity 1.0 NTU, temperature 28.1 °C, color 3.63 TCU, total dissolved solids (TDS) 10.2 mg/L, nitrate (NO3-) 0.608 mg/L, nitrite (NO2-) 0.002 mg/L, iron (Fe) 0.038 mg/L, and manganese (Mn) 0.006 mg/L.
