The persistent climate crisis has directly affected the social system. In response to environmental changes, communities reconfigure their abilities by reshaping their everyday lives for sustainability and survival. This study’s main objective is to examine how social capital was utilized by selected community members of Brgy. San Antonio and Brgy. Tagumpay in Bay, Laguna, Philippines as a form of adaptation to flooding. Households from Purok 6 of Brgy. San Antonio and Brgy. Tagumpay were selected through purposive sampling and complete enumeration, respectively. Utilization of the means of association at 0.05% level of significance showed that specific socio-demographic variables had a direct association with social capital resources within the community. The adaptive capacity of the participants was strengthened through relationships with their support system and their active participation in group/association activities. For attachment to neighborhood, the variable that had the most significant relationship with most of the socio-demographic characteristics was the strengthening of the spirit of collective community through the existence of formal and informal organizations. Access to resources and services helped to enhance the adaptive capacity of the community members. Adaptability became more apparent when financial and social services were within one’s reach. The closeness of relationships between neighbors helped to strengthen their adaptive capacity. In community relationships, trustworthiness was considered as the most significant value. It is recommended that social capital be strengthened to enhance adaptive capacity.

The study quantified the recreational benefits of Consocep Mountain Resort for the current and hypothetical improvement of the area. Recreation sites revealed their economic value through the services that they provide. However, these services do not command a price, which leads to an underestimation of their value. The travel cost method is one of the methods for estimating recreational values by converting physical and social benefits into monetary terms. The travel cost method was used to estimate the economic use value of Consocep Mountain Resort in its present condition by using visitors’ actual expenditures. Contingent behavior was added to compute the change in welfare, assuming that an improvement will occur and an additional access fee will be implemented. Given the current site condition of the area, the consumer surplus of a single visit per tourist is PhP 2,136.75 (US$ 41.41), while the consumer surplus for an improved visit is PhP 3,539.82 (US$ 68.60). visitors give high value to the site. Therefore, these information can be used as guide for managing the area. Conservation of resources is also important so that the benefits received by the present population can be enjoyed by generations to come.

Potential toxic elements, such as Arsenic (As), Cadmium (Cd), Copper (Cu), Lead (Pb), and Zinc (Zn) are commonly left behind after mining operation. Being non-biodegradable, these elements serve as source of contamination for the soil and water ecosystems and create hazards to human health. This research work evaluated the phyto extracting ability for potential toxic elements by four endemic tree species, such as Betula pendula (Birch), Carpinus betulus (Hornbean), Fagus sylvatica (Beech), and Salix caprea (Goat willow). These tree species are predominantly growing in an abandoned mining spoil sites in Mátra Mountains, Hungary. Plant and soil samples were collected in the field and analyzed using inductively coupled plasma-atomic emission spectrometry (ICP-OES) method. The soil was highly contaminated with heavy metals, such as Pb, As, and Zn which were 10 to 60 times more than the typical non-contaminated Hungarian soil. Among the trees evaluated, Carpinus betulus showed the highest potential for Pb dendroremediation, with a mean concentration value of 4071.67±45.71 mg kgˉ¹ dry weight in roots, 439.05±1.06 mg kgˉ¹ dry weight in stems and 92.53±0.73 mg kgˉ¹ dry weight in leaves. Betula pendula and Salix caprea bioaccumulated 475.575±2.219 and 395.97±1.43 mg kgˉ¹ dry weight of Zn in their leaf biomass. Both trees had a Bio-concentration Factor (BCF) value of greater than 1.0 but less than 10 which classified them as potential phytoextractors of Zn. Salix caprea gave the highest Translocation Factor (Tf) for Cd while Betula pendula gave the highest Tf for Zn.

The selection of forest trees as planting materials in reforestation projects or plantation development could be based on the existing needs of the wood-based industry, and in support of the National Greening Program. It is anchored on natural adaptation to ensure high survival rates considering suitability to prevailing site conditions; purpose for planting; availability of planting stocks; and commercial value. Thus, selection and mapping of plus and mother trees at the northeastern slope of Mt. Banahaw de Lucban, Philippines were conducted to determine potential seed production areas as sources of quality planting materials. Information materials were developed for dissemination. Twenty-two species with 65 individuals representing families of Annonaceae, Fabaceae, Fagaceae, Clusiaceae, Meliaceae, Myrtaceae, Podocarpaceae, Sapindaceae, Sapotaceae, Symplocaceae, Theaceae and Tiliaceae showed vigorous growth and superiority in height and diameter compared with the surrounding trees. Phenotypic characteristics are influenced by temperature, rainfall, soil and elevation. Highest population of plus trees was distributed in moderate to steep slope. Favorable soils for growth were found at lower elevations. Species diversity of 2.00 showed moderately diverse plus trees at 700 masl and 800 masl. However, 11 species were found threatened as listed on DENR Administrative Order (DAO) No. 11, s. 2017 and the International Union for Conservation of Nature (IUCN).

Phytoremediation of mine wastes is a promising approach for the restoration of contaminated soils. Miscanthus floridulus is a perennial herbaceous grass with high productivity and tolerant to a variety of heavy metals. Sixty-day pot experiments were carried out to investigate the effects of combined Pb-Cu contamination on some physio-biochemical markers of M. floridulus and rhizospheric soil enzyme activities. M. floridulus was tolerant to a combination of 200 mg kg-1 Pb and 100 mg kg-1 Cu stress as indicated by invisible foliar injury, increased contents of photosynthetic pigments (increased by 17.2% to 22.8% compared to the control), enhanced accumulation of soluble sugar contents by 33.5% to 52.8% in response to all treatments except the Pb100Cu50, decreased contents of malondialdehyde by 5.18% at 100 mg kg-1 Pb and 50 mg kg-1 Cu. As a response to combined Pb-Cu stress, the antioxidant enzymes (catalase, peroxidase and superoxide dismutase) activities in M. floridulus were reduced by any of the Pb-Cu treatments used in the present study. Although the growth parameters such as plant height, root number, maximal root length, and the dry biomass of aboveground parts and root were all lowered by Pb-Cu treatments, the rhizospheric soil invertase, catalase, urease and phosphatase enzyme activities of M. floridulus kept increasing when the concentration of Pb and Cu below 400 mg kg-1 Pb and 200 mg kg-1 Cu.

This research aims to reveal the extent on how governance culture is embedded in climate policy innovation processes in the Turkish context. In Turkey, the process deal with multilateral climate policies started in 2004, when the country announced to be a party of United Nations Framework Convention on Climate Change (UNFCCC). However, climate policies started to be developed in the 1990s, when the importance of governance began to gain considerable recognition. It is now possible to discuss to what extent governance-based approach has been followed in the processes of climate policy innovation until 2016, since it has been a quarter century from when the time both climate policies and governance began to take place on the public agenda in Turkey. In order to achieve its aim, the study focuses on the extent all related stakeholder groups participation in policy innovation processes in the case of the Coordination Board of Climate Change and Air Management (CBCCAM) through document analysis technique. The research reveals that governance culture has not been embedded in climate policy innovation processes in Turkish context. This study could help to provide a critical view of the embeddedness of governance culture in climate policy innovation processes through focusing on CBCCAM in Turkey.

Environmental regulation is not only an effective method to control pollutants and wastes, but also a vital factor that can be used to influence industrial structure. This study applies the panel data of 285 prefecture-level cities in China from 2004 to 2016 to verify spatial autocorrelation between industrial structure upgrading and regional environmental regulation and then uses dynamic spatial panel model (DSPM) to verify how regional environmental regulation both directly and indirectly influences industrial structure upgrading. There is a close spatial autocorrelation in Chinese cities between industrial structure upgrading and regional environmental regulation. The estimation results of DSPM show that regional environmental regulation only acts on that particular region’s industrial structural upgrading but not on the upgrading in other regions. The heterogeneity results show that from economic development, human capital, and foreign direct investment perspectives, regional environmental regulation is also able to reduce the negative impacts of industrial structure upgrading. The strengthening of both infrastructure and government intervention promotes industrial structure upgrading. This study provides effective empirical support for adjustments to China’s industrial structure and regional environmental regulation policy making.

Urban agglomeration in Butuan City led to issues on solid waste management (SWM). The socioeconomic profile and effectiveness of SWM programs were assessed and evaluated through a survey questionnaire. Using a 5-point Likert scale to measure the knowledge, attitude, and practices towards SWM. Key informant interviews and focused group discussions were also conducted. On the average, respondents showed very high SWM knowledge (3.80) and attitude (4.52) which was attributed to high educational attainment and income. Majority of the respondents practice waste segregation (97.9%), reusing (83.8%), recycling (70.4%) and composting (61.3%). However, low knowledge on the location (35.6%), functionality (33.7%), and utilization (51.3%) of the materials recovery facilities was noted, an indication of non-compliance by local government units to SWM laws and policies. A significant number of respondents do not practice composting (38.7%) due to lack of facilities and available space. Clustered materials recovery and composting facilities, and adjustments on waste collection, storage, and disposal systems must be established and implemented. Incentive programs, awareness campaigns, and public participation are key elements of an efficient SWM system.

Air pollution is a major concern worldwide with human activities being the main contributor and causing serious health impacts. The present study was designed to monitor the amount of gaseous pollutants (CO2, CO, SO2, NOX) and total suspended particulates (TSP) from different industrial boiler’s exhaust using three fuel types (coal, natural gas and heavy furnace oil/diesel). These five parameters were measured and compared with the National Environmental Quality Standards (NEQS) of Pakistan. Coal and diesel boilers were emitting more SO2 (22x) as compared to natural gas. The natural gas boilers were producing more CO (7x) due to inefficient combustion and low mixing of air into gaseous fuel. The concentration of NOx from all boiler types were within the standard value. TSP values ranged from 82.3 mg m-3 to 245.7 mg m-3, which were within the NEQS limits due to the presence of control devices. Workers’ health (n=42) was assessed using a questionnaire and health of many workers was found to be compromised (34 %), while most of them were either unaware or were not provided PPEs (37.5%). Consequently, the workers were being exposed to large amounts of hazardous emissions in the industry.

The present study was designed to monitor the amount of gaseous pollutants (CO2, CO, SO2, NOX) and total suspended particulates (TSP) from different industrial boiler’s exhaust using three fuel types (coal, natural gas and heavy furnace oil/diesel). These five parameters were measured and compared with the National Environmental Quality Standards (NEQS) of Pakistan. Coal and diesel boilers were emitting more SO2 (22x) as compared to natural gas. The natural gas boilers were producing more CO (7x) due to inefficient combustion and low mixing of air into gaseous fuel. The concentration of NOx from all boiler types were within the standard value. TSP values ranged from 82.3 mg m-3 to 245.7 mg m-3, which were within the NEQS limits due to the presence of control devices.

Catchment classification is one approach in natural resource management that is widely adopted in taking efficient steps towards implementing suitable soil and water conservation measures across a basin or region. Catchments have unique characteristics emerging from the heterogeneity and complexity of the systems and classifying them paves way to achieve order and simplicity. However, some constraints related to data availability could be a problem in a region where only few rivers are gauged and with only one type of climate data available. This study presents a way to decrease complexity by grouping these catchments based on their biophysical characteristics extracted from readily available datasets and using simple statistical approaches. Principal component analysis was first conducted to twenty-four biophysical variables which were reduced to eight factor components. A hierarchical clustering method was then performed to define the number of clusters and K-means clustering procedure was followed for the final grouping. Nine watershed clusters were formed with watershed size having the greatest contribution. Grouping catchments into clusters with similar biophysical characteristics does not only promote simplicity but also facilitates understanding of the nature of not only one watershed but also its relationship with other watersheds in a bigger landscape. The study also confirmed that spatially close watersheds exhibit similar characteristics.
