Policies without behavioral results or when environmental policy becomes robust

2025-08-12T23:34:36+00:00

The article focuses on changing individual attitudes and behaviors as key factors for resilient environmental policy. Through representative field studies using a specially designed questionnaire, the subjectively declared levels of ecological perceptions and pro-environmental behaviors of citizens at the national level in Bulgaria and residents of one of the country’s municipalities, which self-identifies as a “green municipality”, were compared. The main research question is whether citizens in a local community, where there is a sustainable agreement on broadly formulated environmental goals and corresponding active pro-environmental policies, demonstrate a greater personal commitment to the environment, materializing in increased levels of knowledge and individual pro-environmental behavior. The main conclusion is that active environmental policy does not necessarily change public attitudes and individual behavior following their goals.

An investigation of water quality index and health risks of fluoride and nitrate in the arid groundwater (India)

2025-07-11T10:21:34+00:00

Groundwater in arid regions such as Northwestern Rajasthan of India is under increasing pressure due to climatic extremes, excessive extraction, and contamination from both geogenic and anthropogenic sources. This study assesses the seasonal dynamics of groundwater quality in Bikaner, focusing on fluoride and nitrate contamination and their implications for drinking suitability and public health. Twenty samples were collected from tube wells during the monsoon (2019) and pre-monsoon (2020) periods and analysed for a suite of physicochemical parameters following standard protocols. Water usability was gauged using several parameters including pH, electrical conductivity, total hardness, total dissolved solids, and ions such as calcium, magnesium, potassium, sodium, bicarbonate, carbonate, chloride, fluoride, nitrate and sulphate, while overall quality was synthesized using the Water Quality Index (WQI). Spatial patterns of contamination were visualized through geostatistical mapping, and hydrochemical facies were interpreted via Piper diagrams. Results revealed that over 65% of pre-monsoon samples surpassed WQI thresholds for safe use, signalling deteriorating groundwater quality. Elevated concentrations of fluoride (up to 5 mg/L) and nitrate (up to 320 mg/L) were commonly detected, with several areas falling into unsuitable categories for drinking. A health risk assessment using the Hazard Index framework found that all demographic groups especially infants were exposed to non-carcinogenic risk, with HI values reaching beyond 12 in critical zones. These findings underscore the urgent need for localized groundwater management strategies in the arid regions where seasonal fluctuations and geogenic factors are intensifying fluoride and nitrate contamination. The spatial clustering of high-risk zones especially in central and southeastern areas suggests persistent vulnerability requiring targeted mitigation. Prioritizing seasonal monitoring, fluoride and nitrate treatment technologies, and community-level interventions to mitigate health hazards and secure water resilience in ecologically fragile region of northwestern Rajasthan.

Growth performance of lapnisan (Aquilaria malaccensis Roxb) seedlings in varying sand concentrations

2025-09-11T05:21:26+00:00

The International Union for Conservation of Nature (IUCN) Red List has categorized the Southeast Asian native species Aquilaria malaccensis as severely endangered due to the great demand for its agarwood. The purpose of the study was to assess the growth performance of Lapnisan (Aquilaria malaccensis) seedlings in varying sand concentrations. The study employed a Complete Randomized Design (CRD) method with four treatments, this include Treatment 1 (T1)-pure top soil, Treatment 2 (T2)- topsoil and sand soil (1:1 ratio), Treatment 3 (T3)- topsoil and sand soil (3:1 ratio), and Treatment 4 (T4)- topsoil and sand soil (1:3 ratio) with three replications per treatment. The effects of these treatments were evaluated based on percent survival, number of leaves, branches and stem diameter. Based on the study, there were significant differences among the treatments. Lapnisan seedlings in T2 produced more branches (3.78) and a greater number of leaves (39.56) compared to the other treatments. In contrast, Lapnisan in T3 developed a thicker stem diameter (6.89). Notably, Lapnisan seedlings in Treatment 4 achieved a 100% survival rate out of the four treatments. These results suggested that a high sand concentration is the most suitable for cultivating Lapnisan seedlings, as it significantly increased their chance of survival.

Landscapes connectivity in river Bregalnica watershed - determining the relative importance of rural landscapes for European wildcat conservation

2025-12-22T18:53:25+00:00

Maintaining and enhancing habitat connectivity in semi-natural and cultural landscapes is essential for preserving biodiversity, ecosystem health, and the well-being of both wildlife and human communities. In this regard, this study aims to assess landscape connectivity across different landscape types in Bregalnica watershed, with a specific focus on evaluating the role of rural landscapes as corridors for the European wildcat (Felis silvestris Schreber, 1777).
Connectivity analysis was conducted in Graphab 2.8, using 50x50m rasterised habitat map as a baseline. A minimum patch size of 300 ha was applied to define habitat nodes, and a 1,500 m dispersal threshold was used for species movement through unsuitable habitats.
Forest landscapes within the Bregalnica watershed were found to have the highest cumulative core patch value. Rural landscapes—while secondary to forests—also provide habitat for the wildcat and play a significant role in supporting habitat connectivity for the species. Three rural landscape types support European wildcat populations by providing suitable habitat and enabling connectivity between populations: Hilly rural landscape, Mountain rural landscape and Osogovo mountain rural landscape. Among these, the latter is the most critical for core area presence and connectivity. The Hilly rural landscape is the most valuable in terms of corridor presence.
The outputs of this study contribute towards wildlife conservation efforts and the integrated management of ecological networks in the Bregalnica watershed region.

Down dead wood in a montane beech forest stands on Deshat Mountain. 5. Impact of forestry management practices

2025-12-22T18:59:40+00:00

Down dead wood (DDW) is a crucial component of forest ecosystems contributing to decomposition, nutrient cycling, soil formation and biodiversity. Despite its ecological significance, historical and ongoing forest exploitation has led to a decline in DDW, particularly in coppice forests. This study was conducted in montane beech forests on the eastern slopes of Deshat Mountain, in the Mavrovo National Park in North Macedonia. Its aim was to assesse the impact of traditional forestry practices on the amount of down dead wood and other forest parameters. Five forest stands were selected based on differences in forest management and stand structure. In each stand, three sampling plots (15 in total) were established to assess tree density, diameter at breast height (DBH) and shrub presence. Down dead wood (DDW) biomass was estimated by recording all fallen tree logs and categorizing their decay into five classes. Tree density in the investigated beech forests on Deshat Mountain varied significantly, with the highest recorded in coppice forest (7817 trees/ha) and the lowest in old-growth forest (1356 trees/ha). DBH ranged from 3 to 85 cm, with smaller trees (DBH 3–17 cm) dominating across all stands. A significant negative correlation was observed between stand density and dead branch biomass, indicating that intensive forest use near villages has reduced DDW availability. The spatial gradient of DDW accumulation suggests that human impact, particularly firewood collection by the local community has shaped forest structure. Historical and ongoing anthropogenic influences, coupled with rural depopulation, have altered DDW dynamics, with remote stands retaining more deadwood due to limited accessibility. These findings highlight the need for forest management strategies that balance conservation with sustainable resource use.
