Peri-urban agriculture potentially serves as an essential green infrastructure, facilitating sustainable transitions within cities by providing crucial local food ecosystem services to urban populations. This study centers on L’Horta de València, a historically significant agricultural area surrounding the city of Valencia, Spain, which has been operational for an extended period. Legislative protection for the area was established in 2018, followed by the approval of a management plan in 2019, both formulated to regulate land use and stimulate agricultural activities. While it remains premature to assess the outcomes of these measures, an evaluation of the ongoing positive and negative transformations is feasible. This paper presents research aimed at addressing this objective and poses the question: To what extent are the newly implemented tools rectifying the originally identified issues? The study employed a semi-structured survey, administered to key specialists who were directly involved in the formulation process of the approved plans and represent a diverse array of stakeholders. The survey concentrated on a SWOT analysis, with the results organized along the following themes: governance of the agricultural area, behavior of major powers, social agent behavior, agricultural profitability, agrarian policy, market knowledge, farmer-society communication, environmental concerns, technical innovation, new transport infrastructure and urban development, and cultural services.

This study aimed to examine the effect of environmental awareness on attitudes and intentions to reduce food waste, as well as the impact of intention to reduce food waste on behavior to reduce food waste among Generation Z in Indonesia. Given this generation's critical role in shaping sustainable practices for the future, understanding their attitudes and behaviors toward food waste is vital. By addressing this gap in the literature, the research aims to contribute to more effective strategies for promoting environmentally conscious behaviors among Gen Z, ultimately leading to a reduction in food waste and its associated environmental impacts. This study applies the convenience sampling technique. The questionnaires were distributed online via a google form. The respondents came from several big cities on the island of Java, such as Jakarta, Tangerang City, South Tangerang City, Bekasi City, Depok, Bogor City, Bandung, Yogyakarta, Semarang, and Surabaya. The total population on the island of Java is 151.6 million, which means 55 percent of Indonesia's 273.5 million total population. The total sample collected and analyzed in this study was 1,000 samples. The study's results prove that environmental awareness has a positive and significant effect on attitude (the T-statistics value of 14,286 > 1.96, and the p-value is 0.00 < 0.05) and intention to reduce food waste (the T-statistics value of 3.845 > 1.96 and the p-value is 0.00 < 0.05). Then, the attitude was also proven to have a positive and significant effect on the intention to reduce food waste (the T-statistics value of 11.579 > 1.96, and the p-value is 0.00 < 0.05). Finally, the intention to reduce food waste is proven to have a positive and significant effect on behavior to reduce food waste (the T-statistics value was 14,000 > 1.96, and the p-value was 0.00 < 0.05). This study contributes to the literature by investigating the relationship between environmental awareness, attitudes, intentions, and behavior toward food waste reduction among Gen Z in Indonesia. The findings highlight environmental awareness's positive and significant effects on attitudes, intentions, and subsequent behaviors to reduce food waste, providing valuable insights for developing targeted interventions and campaigns to promote sustainable practices among Gen Z.

Sustainable development is growth that respects, without compromising, the needs of present and future society. Such sustainability is currently implemented in our society, which has absorbed and processed resources unconsciously for decades. The main objective of this research is to evaluate water sustainability in Panama through the Multi-Scale Integrated Analysis of Social and Economic Metabolism (MuSIASEM) or MuSIASEM scheme, which allows interrelating aspects of Panamanian society to create a metabolic pattern from 2004 to 2019. This methodology analyzes the country's economic, water and demographic variables, studying their interrelation to generate the socioeconomic metabolism. Thus, water consumption, Gross Domestic Product (GDP), and the Panamanian population were studied for the selected period. From the database, Panamanian demography has grown linearly during the period studied with a service economy mostly. Concerning the interrelation of the variables, except for the government sector, all sectors showed a correlation between the variables. This correlation reveals the influence between economic growth and water consumption. In conclusion, we emphasize the influence of the State in water sustainability, implementing measures to make efficient use of resources and enhance the economy-also the capacity of the MuSIASEM grammar as a holistic tool for such analysis.

Disposal of solid waste is a major challenge in towns and cities due to waste being dumped at an unacceptable site. The designation of a landfill site is a challenge in Thohoyandou town. The purpose of this study was to determine a user-friendly landfill site location for Thohoyandou town. The study also intended to examine the social implications of the existing landfill site location on the communities. Data was gathered using both qualitative and quantitative methods. Data was acquired using questionnaire surveys, interviews, field survey, observations, and secondary sources. The data was analyzed using the Statistical Package for Social Scientists, and the Chi-square test. Geographical Information Systems (GIS) and Remote Sensing (RS) constitute the major methods used to determine an acceptable site for the disposal of solid waste generated in study area. The existing landfill site in the study area is not in line with environmental and social standards due to waste being dumped at an unacceptable site. The study revealed social problems such as bad smell, diseases, noise, dust and decline of standards of living in which all have emerged because of the Thohoyandou Block J landfill site. To overcome these challenges, this study incorporated six environmental parameters, including: proximity to road networks, slope, soil, land use/land cover, and built-up areas; surface water, to determine the best suitable landfill site in the study area. According to the findings of this study, out of five potential landfill sites, the site which had the highest rankings following the Analytical Hierarchy Process (AHP) was selected as the most suitable landfill site. As a result, the research recommends that Thulamela Local Municipality contemplate terminating its existing landfill site to relocate to one of the alternative acceptable sites identified by this study.

The escalating impacts of anthropogenic activities and natural disasters, aggravated by economic crises, have amplified the vulnerability of environmental and territorial systems, leading to significant urban planning and social implications. Consequently, numerous public and private buildings have been abandoned, necessitating crucial reorganizations or repurposing to prevent degradation and obsolescence due to disuse. The imperative goal is to foster resilience within territories, primarily by enhancing the adaptability of urban assets to altered conditions induced by both natural and anthropogenic disturbances, thereby increasing their inherent flexibility to offer functional responses to disruptions. This approach aims to mitigate adverse effects, expedite restoration of the status quo or augment the adaptability of structures, particularly public and strategic ones, during extraordinary phases. The proposed methodology for fortifying solidity and fostering resistance to change in the built environment involves digital cataloguing of heritage through the creation of three-dimensional models of structures. This process, known as Building Information Modelling (BIM), is predicated on a preliminary analysis of structural, architectural, and plant engineering data, which is beneficial for both ordinary and atypical management. The result is an efficient system that offers facility management opportunities for structures throughout their lifecycle and facilitates optimization of resource use. It aids in evaluating the extraordinary use of assets, examining various performance hypotheses for each scenario, understanding the time required for system setup, and determining relative economic indicators until the restoration of the preceding state.

Management of municipal solid waste (MSW) is a serious environmental challenge that many nations, particularly developing ones are currently experiencing. As a result, information about the amount and type of MSW is needed to establish an effective waste management strategy. In addition, the amount and type of MSW may change from place to place and season to season. Thus, the purpose of this study was to determine the amount of MSW recovered in the O.R. Tambo District Municipality, Eastern Cape, South African. The first objective of this study was to determine the effect of season on the amount of each waste type (aluminium cans, bottles, cardboards and plastics) recovered. The second objective was to compare the amount of each waste type recovered among the five local municipalities (Ingquza Hill, King Sabatha Dalindyebo, Mhlontlo, Nyandeni and Port St. Johns (PSJ)). The study, which focused on MSW recovered over a two-year period (September 2019 to August 2021), revealed that there were no statistically significant differences in the amount of MSW recovered among the four seasons. However, the type of waste recovered mostly varied significantly across the local municipalities. For example, PSJ had the highest recovery of bottles, while Mhlontlo had the highest recovery of other types of waste. We can conclude that solid waste recovery is crucial since it reduces the amount of waste that must be disposed of in landfills and saves more natural resources.

The following paper is intended to characterize microlitter occurrence in resident fish, bivalves and crustaceans collected from multiple sites NE Baltic Sea-Gulf of Finland, NE Gulf of Riga (Pärnu Bay), and western Estonia (including eastern Baltic Proper, archipelago area, and western coastal area of mainland) according to regionally coordinated Helsinki Commission (HELCOM) methodology. Marine litter and microplastics in gastrointestinal tracts from 11 fish and 6 benthic invertebrate species collected during the period 2019-2020 were evaluated. Analyses of microlitter were based on the suggestions given in Guidance on Monitoring of Marine Litter in European Seas and Monitoring Micro-Litter Ingestion in Marine Fish: a harmonized protocol for Marine Strategy Framework Directive (MSFD) and Regional Sea Conventions (RSCs) areas. All species contained microlitter (over 30% of samples from all individuals, N=1332). Highest microlitter concentrations were found in perch Perca fluviatilis (44%, N=106) and blue mussel Mytilus trossulus (42%, N=241). For Harris mud crab Rhithropanopeus harrisii the percentage was 23% (N=123). Among the three litter categories found, fibers accounted for the highest percentage - 46-100% for fish, 88-91% for bivalves and 75% for crabs. On average the abundance of recorded items was as follows: 0.54 (fish), 0.47 (bivalves) and crabs (0.33) per individual. In majority of analysed bivalves (69.6%, N=675) and fish (61%, N=524) that contained microlitter one microparticle per individual was detected. In case of most fish species, higher number of microlitter was associated with larger size (0.3-5mm) of the ingested particles. Our results reveal the ubiquitous presence of microplastics or other microlitter in organisms across multiple habitats in the NE Baltic Sea. The study identifies potential bioindicator species and provides an important baseline to monitor microplastic pollution in accordance with the MSFD. Among studied species, blue mussel (M. trossulus), Baltic macoma (M. balthica), Harris mud crab (R. harrisii), perch (P. fluviatilis), flounder (P. flesus), and Baltic herring (C. h. membras) were proposed as target species for assessment of ingested litter among invertebrate and fish in NE Baltic Sea.
