A Global Meta-Analysis of the Effects of Greenspaces on COVID-19 Infection and Mortality Rates.

The COVID-19 outbreak in 2020 resulted in rapidly rising infection rates with high associated mortality rates. In response, several epidemiological studies aimed to define ways in which the spread and severity of COVID-19 can be curbed. As a result, there is a steady increase in the evidence linking greenspaces and COVID-19 impact. However, the evidence of the benefits of greenspaces or greenness to human wellbeing in the context of COVID-19 is fragmented and sometimes contradictory. This calls for a meta-analysis of existing studies to clarify the matter. Here, we identified 621 studies across the world on the matter, which were then filtered down to 13 relevant studies for meta-analysis, covering Africa, Asia, Europe, and the USA. These studies were meta-analyzed, with the impacts of greenness on COVID-19 infection rate quantified using regression estimates whereas impacts on mortality rates were measured using mortality rate ratios. We found evidence of significant negative correlations between greenness and both COVID-19 infection and mortality rates. We further found that the impacts on COVID-19 infection and related mortality are moderated by year of publication, greenness metrics, sample size, health and political covariates. This clarification has far-reaching implications for policy development toward the establishment and management of green infrastructure for the benefit of human wellbeing.

Towards Environmental Sustainability: Integrating RS and GIS for Ecology Assessment

The environment provides numerous benefits for human well-being, such as ecosystem services. These services directly and indirectly depend on the physical state of the ecosystem. However, the over-exploitation of natural resources along with socio-economic factors, i.e. economic growth, poverty, agriculture expansion, population growth and weak environmental governance and regulation for fulfilling the human needs for food, fuel, and shelter, is leading to the degradation of the ecological health of an area. Therefore, monitoring and assessment of spatial and temporal changes in the ecology of a region in terms of vital ecological services is very critical and would help the decision-makers to develop and plan appropriate adaptation and mitigation measures for the conservation of natural ecosystems at various scales to ensure environmental sustainability. The present study aimed to assess the ecological status of the Mahi Bajaj Sagar catchment area in Rajasthan (India) from the year 2000 to 2020, using remote sensing-based indices. Indicators such as greenness, dryness, and heat index have been selected as per the pressure-state-response (PSR) framework. Multi-spectral remote sensing data and image processing methods have been used to estimate these indicators, and a remote sensing-based Ecological Status Index (RSBI) has been generated by their integration using the principal component analysis (PCA) to assess the ecological status of the Mahi Bajaj Sagar catchment. Findings from the study indicate a consistent decline in the overall ecological status of the Mahi Bajaj catchment, where decreased forest areas have a pronounced effect on ecological health. Interestingly, approximately 43.6% of the area displayed resilience to changes in ecological status; however, 36.4% of the area exhibited signs of ecological degradation. Our study underscores the efficacy of a remote sensing-based approach in quantifying and detecting ecological changes, offering a promising methodology for monitoring and assessing the ecological health of large areas that can help promote environmental sustainability.

Motivation and perception of farmers on the benefits and challenges of agroforestry in Sweden (Northern Europe)

Agroforestry systems provide multiple benefits for human wellbeing and biodiversity; however, their diversity and spatial distribution has sharply declined across Europe. This study focuses on agroforestry farms in Sweden. The aim of the study was to explore farmers’ motivations to start agroforestry, what benefits farmers attributed to their agroforestry farms and perceived challenges to practising agroforestry in Sweden. In total, 13 farms that practise various agroforestry forms were selected as case studies. A focus group, semi-structured interviews and field observations were used for data collection. We identified four types of agroforestry systems such as silvopasture, silvoarable, forest farming and forest gardens established on different land such as forested or agricultural land. All studied agroforestry farms were small but had complex spatial and temporal arrangements of crops, trees and animals, which were crucial to generating multiple benefits. Our results show that the multifunctionality of agroforestry systems resulted from farmers’ desire to design such systems. Farmers’ intentions to get foods and materials from their farms were always intentionally unified with multiple ecosystem services. We argue that agroforestry farmers are designers of multifunctional landscapes, as they deliberately organised their farming activities to get a bundle of ecosystem services belonging to all four categories—provisioning, regulating, supporting and cultural. However, the complexity of agroforestry management, lack of technologies suitable for small-scale agroforestry farms, limited plant materials (including seedlings) and limited knowledge about how to do agroforestry challenged the scaling up of agroforestry practices.

Development at the cost of unsustainable degradation of wetlands: Unraveling the dynamics (historic and future) of wetlands in the megacity Dhaka

Despite the recognized role of wetlands in providing ecological benefits for human wellbeing, ∼70% of global wetland ecosystems have been destroyed since the 1990s. Further intensive studies revealed that 3.4 million km2 of natural wetland has declined since 1700. In particular, wetland habitats in the world's megacities have been replaced unsustainably by faster economic, urban, and population growth, and have received less attention in research and policy. However, wetlands degradation in the megacities of developing countries is not quantified and the trends of Land Surface Temperature (LST) are not well understood. Therefore, we are making our first attempt to unravel the historical and future spatiotemporal dynamics of wetlands and the trends of LST in the megacity of Dhaka. The results show that Dhaka lost ∼69% of wetlands and LST has increased between 3.44°C and 9.35°C from 1990 to 2020. An environmental Kuznets curve analysis implies that the point has not yet been reached for wetlands when economic development feeds back to the sustainability of the environment. This assumption coincides with our model-based prediction, as respectively ∼74% and ∼90% of wetlands area of Dhaka city will be decreased by 2050 in Business as Usual (BAU) and development scenarios, whereas, ∼66% of wetlands area will be decreased under conservation scenario over the time period of next 30 (2020 to 2050) years. Our findings suggest that it will be incredibly challenging to restore wetlands to their 1990s condition. Efforts to preserve them should be made, as they potentially provide a nature-based alternative for coping with wetland sustainability and climate change.

Street trees provide an opportunity to mitigate urban heat and reduce risk of high heat exposure

Climate change is exacerbating the need for urban greening and the associated environmental and human well-being benefits. Trees can help mitigate urban heat, but more detailed understanding of cooling effects of green infrastructure are needed to guide management decisions and deploy trees as effective and equitable climate adaptation infrastructure. We investigated how urban trees affect summer air temperature along sidewalks within a neighborhood of Tacoma, Washington, USA, and to what extent urban trees reduce risks of high summer temperatures (i.e., the levels regulated by state outdoor heat exposure rules intended to reduce heat-related illnesses). Air temperature varied by 2.57 °C, on average, across our study area, and the probability of daytime temperatures exceeding regulated high temperature thresholds was up to five times greater in locations with no canopy cover within 10 m compared to those with 100% cover. Air temperatures decreased linearly with increasing cover within 10 m, suggesting that every unit of added tree cover can help cool the air. Our findings highlight the value of trees in mitigating urban heat, especially given expected warming with climate change. Protecting existing urban trees and increasing tree cover (e.g., by planting street trees), are important actions to enhance climate change resilience of urban areas.

Knowledge influences perceptions and values of nature-based solutions: The example of soil and water bioengineering techniques applied to urban rivers

Soil and water bioengineering (SWBE) is a nature-based solution (NBS) that can be used to stabilize riverbanks with living vegetation. Aside to protecting property and people, SWBE provides benefits for human well-being and biodiversity. Its use remains modest in cities, where the presumed benefits are important in a context of biodiversity crisis and warming. Negative public perceptions have been identified as one barrier to the dissemination of NBS. This article studies how environmental expertise influences perceptions and values associated with SWBE, and how the possible differences in perceptions and values induced by knowledge contribute to hindering or promoting the dissemination of these solutions. We carried out an original interdisciplinary study based on a sociological survey and ecological field measurements to characterize: (1) the perceived value that actors associate with several riverbanks equipped with different protection structures (green, hybrid, or gray) according to their level of expertise in the aquatic environment; (2) the interactions between these perceived values and the ecological values measured by restoration ecologists; and (3) the perceived benefits and drawbacks of SBWE techniques. Our results show that the ecological and social benefits provided by NBS are recognized by all, whatever their level of knowledge. Despite this consensus, we observed different hierarchies of value associated with bank protection structures among the surveyed actors, depending on their level of environmental expertise (some prioritising ecological values, others relational values), and these could hinder the dissemination of NBS. The most tangible obstacle to the dissemination of NBS in urban areas relates to the risk perceptions of lay people, who experience a higher sense of vulnerability than they do with traditional gray solutions.

Smart Nanomaterial for Environmental Remediation towards Sustainable Solutions for Water and Soil Pollution

This research explores the transformative potential of nanomaterial developments in tending to water and soil contamination through economical natural remediation procedures. Three unmistakable nanomaterials, Nanoparticle A, Nanocomposite B, and Nanotube C, were synthesized and efficiently assessed for their adequacy in poison expulsion. In adsorption tests, Nanocomposite B showed remarkable lead expulsion capacity, outperforming Nanoparticle A and Nanotube C with values of 30 mg/g. Catalytic debasement tests illustrated Nanocomposite B’s predominant proficiency in corrupting phenol, accomplishing a noteworthy 68%, outflanking Nanotube C and Nanoparticle A. A comprehensive natural compatibility appraisal uncovered decreased ecotoxicity and cytotoxicity files for Nanocomposite B, situating it as a naturally inviting choice for remediation. Comparative investigations with related works exhibit the importance of fitting nanomaterial properties focused on poison expulsion. The promising results emphasize Nanocomposite B’s potential as a maintainable and multifunctional arrangement for water and soil remediation. This investigation contributes profitable insights to the developing field of nanotechnology-enabled natural administration, emphasizing the requirement for the capable sending of nanomaterials to attain long-term environmental and human well-being benefits.

How Rearing Systems for Various Species of Flies Benefit Humanity

Flies (Diptera) have played a prominent role in human history, and several fly species are reared at different scales and for different beneficial purposes worldwide. Here, we review the historical importance of fly rearing as a foundation for insect rearing science and technology and synthesize information on the uses and rearing diets of more than 50 fly species in the families Asilidae, Calliphoridae, Coelopidae, Drosophilidae, Ephydridae, Muscidae, Sarcophagidae, Stratiomyidae, Syrphidae, Tachinidae, Tephritidae, and Tipulidae. We report more than 10 uses and applications of reared flies to the well-being and progress of humanity. We focus on the fields of animal feed and human food products, pest control and pollination services, medical wound therapy treatments, criminal investigations, and on the development of several branches of biology using flies as model organisms. We highlight the relevance of laboratory-reared Drosophila melanogaster Meigen as a vehicle of great scientific discoveries that have shaped our understanding of many biological systems, including the genetic basis of heredity and of terrible diseases such as cancer. We point out key areas of fly-rearing research such as nutrition, physiology, anatomy/morphology, genetics, genetic pest management, cryopreservation, and ecology. We conclude that fly rearing is an activity with great benefits for human well-being and should be promoted for future advancement in diverse and innovative methods of improving existing and emerging problems to humanity.

What evidence exists on the performance of nature-based solutions interventions for coastal protection in biogenic, shallow ecosystems? A systematic map protocol

BackgroundAnthropogenic pressures and climate change threaten the capacity of ecosystems to deliver a variety of services, including protecting coastal communities from hazards like flooding and erosion. Human interventions aim to buffer against or overcome these threats by providing physical protection for existing coastal infrastructure and communities, along with added ecological, social, or economic co-benefits. These interventions are a type of nature-based solution (NBS), broadly defined as actions working with nature to address societal challenges while also providing benefits for human well-being, biodiversity, and resilience. Despite the increasing popularity of NBS for coastal protection, sometimes in lieu of traditional hardened shorelines (e.g., oyster reefs instead of bulkheads), gaps remain in our understanding of whether common NBS interventions for coastal protection perform as intended. To help fill these knowledge gaps, we aim to identify, collate, and map the evidence base surrounding the performance of active NBS interventions related to coastal protection across a suite of ecological, physical, social, and economic outcomes in salt marsh, seagrass, kelp, mangrove, shellfish reef, and coral reef systems. The resulting evidence base will highlight the current knowledge on NBS performance and inform future uses of NBS meant for coastal protection.MethodsSearches for primary literature on performance of NBS for coastal protection in shallow, biogenic ecosystems will be conducted using a predefined list of indexing platforms, bibliographic databases, open discovery citation indexes, and organizational databases and websites, as well as an online search engine and novel literature discovery tool. All searches will be conducted in English and will be restricted to literature published from 1980 to present. Resulting literature will be screened against set inclusion criteria (i.e., population, intervention, outcome, study type) at the level of title and abstract followed by full text. Screening will be facilitated by a web-based active learning tool that incorporates user feedback via machine learning to prioritize articles for review. Metadata will be extracted from articles that meet inclusion criteria and summarized in a narrative report detailing the distribution and abundance of evidence surrounding NBS performance, including evidence clusters, evidence gaps, and the precision and sensitivity of the search strategy.

The role of ethics in technology acceptance: analysing resistance to new health technologies on the example of a COVID-19 contact-tracing app

ABSTRACT New health technologies promise enormous benefits for human wellbeing, yet their diffusion is often inhibited by potential users’ uncertainty about their consequences. Since ethics help individuals to cope with uncertainty, this study investigates the potential of ethics to promote technology acceptance. To this end, we test the influence of typical acceptance predictors (perceived health threat, privacy attitudes, and technology readiness) and two new ethics-related variables (‘ethical optimism’ and ‘perceived governmental responsibility’) on resistance to a government-issued COVID-19 contact-tracing app. Using structural equation modelling, we find significant effects of the typical acceptance predictors, and that ethical optimism and perceived governmental responsibility interact in determining the resistance to the tracing app. The paper highlights the relevance of ethics for the acceptance of new (health) technologies and suggests that the role of ethics is not confined to being a ‘moral watchdog’ but can serve as a powerful lever to promote their acceptance.

Does experimental seaweed cultivation affect benthic communities and shorebirds? Applications for extensive aquaculture.

Extensive seaweed aquaculture is a growing industry expected to expand globally due to its relatively low impact and benefits in the form of ecosystem services. However, seaweeds are ecosystem engineers that may alter coastal environments by creating complex habitats on previously bare mudflats. These changes may scale up to top-consumers, particularly migratory shorebirds, species of conservation concern that regulate trophic webs at these habitats. Understanding how habitats are transformed and how this affects different species is critical to direct ecological applications for commercial seaweed management. We experimentally assessed through a Before-After Control-Impact design the potential changes exerted by Gracilaria chilensis farming on bare mudflats on the abundance, biomass, and assemblage structure of benthic macroinvertebrates, and their scaled-up effects on shorebirds' habitat use and prey consumption. As predicted, experimental cultivation of G. chilensis significantly affects different components of biodiversity that scale-up from lower to upper trophic levels. The total biomass of benthic macroinvertebrates increased with seaweed cultivation and remained high for at least 2 months after harvest, boosted by an increase in the median size of polychaetes, particularly Nereids. Tactile-foraging shorebirds tracked these changes at the patch level increasing their abundance and spending more time foraging at seaweed cultivated plots. These results suggest that seaweed farming has the potential to impact shorebird populations by favoring tactile-foraging species which could lead to a competitive disadvantage to species that rely on visual cues. Therefore, the establishment of new seaweed farms in bare mudflats at key sites for shorebirds must be planned warranting habitat heterogeneity (i.e., cultivated and non-cultivated areas) at the landscape level and based on a previous experimental approach to account for local characteristics. Fostering properly designed extensive seaweed farming over other aquaculture industries with greater negative environmental impacts would provide benefits for human well-being and for ecosystem functions.

Ecosystem Service Concept as a Rationale for Urban Green Space Conservation- A Systematic Review Report

Urban Green Space (UGS) is recognized as vital to modern infrastructure development worldwide. While the conventional method of urban planning has long prioritized built structures over UGS, an increasing number of scientific studies have demonstrated that UGS not only supports biodiversity but also provides numerous essential benefits for humans, such as clean air, water, weather regulation, food, and a place for respite for urban residents. This points to a need for an interdisciplinary synthesis of recently published research to document the ecological and social benefits and present comprehensive recommendations. We conducted an in-depth review of existing scientific literature to explore supporting, regulating, cultural, and provisioning ecosystem services benefits, major factors enhancing them, and management recommendations to optimize those benefits. The results indicate that optimizing heterogeneous UGS coverage as an essential part of urban design benefits natural as well as human communities in the form of enhanced wildlife habitat, clean air and water, weather regulation, and livability. Findings highlight the multifaceted contributions of UGS in maintaining natural ecosystems to provide essential benefits for human wellbeing and environmental health, which are integral components of sustainable development. We discuss evidence-based recommendations for policy and planning for optimum UGS suitable for different environmental, geographic, ecoclimatic, and socioeconomic statuses worldwide. The availability of comprehensive information on the enhanced benefits of UGS renders new directions and impetus for UGS conservation in the era of expanding urbanization and climate change.

Assessment of the Interactions between the Landscape and Natural Resource Social Values within the Framework of the Social-Ecological Landscape System

Landscape and natural resource social values (e.g. wilderness and aesthetic) provide essential benefits for human wellbeing. Understanding such community values are essential to predict human behaviours towards nature and also to develop relevant policies and management strategies. Accordingly, the purpose of this theoretical paper was to examine the cross-scale interactions between the landscape and natural resource social values within the framework of the social-ecological landscape system. In doing so, the objectives of the study were (i) to explore the concept and major landscape social values, (ii) to examine the theory and major natural resource social values, (iii) to evaluate the cross-scale interactions between both value systems, and (iv) to design a relevant theoretical framework. The method of the study was based upon the in-depth literature review concerning the landscape and natural resource social values, their typologies, and the potential valuation techniques. The assessment showed that the landscape and natural resource social values are important guiding principles to address a variety of ecological, economic, and socio-cultural benefits for human wellbeing. The typology of the landscape and natural resource social values comprised 16 and 13 major values respectively. However, the types and degrees of both value systems may vary based upon the characteristics of landscapes, ecosystems and associated natural resources, and social systems. The assessment also showed that the landscape and natural resource social values are interconnected through three value scales: spatial, temporal, and social scale. The results of this study can help landscape, land, and natural resource managers to better understand the major landscape and natural resource social values and their cross-scale interactions, which should be integrated into relevant policies and strategies to develop win-win solutions in terms of landscape and natural resource management.

Influences of climate change and land use change on the interactions of ecosystem services in China’s Xijiang River Basin

Ecosystem services (ES) emerge from the complex interactions of diverse ecosystem components. In turn, the provision of ES is influenced by how they are put to use and environmental drivers such as climate change and land use change (CC-LUC). Researches into CC-LUC impacts on ES have so far focused on biophysical supply rather than ES interactions, making it difficult to design appropriate strategies for natural capital investment and the consequent ecosystem benefits for human well-being. In this study, we built networks from correlations among climatic forcing, land-use intensity and ES for the Xijiang River Basin in southern China, a rapidly urbanizing region with rich endowments of ecosystem assets. The variations in network structure were evaluated under different climate and land use projections up to 2035. We found that the CC-LUC-ES networks were more sensitive to land use change which affected the network structure either by directly influencing biophysical ES supplies or indirectly through altering ES interactions. Sustainable land-use management (i.e., ecological protection priority scenario) coupled with the RCP4.5 emission scenario showed higher improvements for both water-erosion prevention and regulating services. Whereas increasing land-use intensity (i.e., economic development priority scenario) with RCP8.5 resulted in losses of ES synergies and a more heterogenous network of greater integrity. Our approach provides a comprehensive view of the relationships among multiple ES and how they respond to CC-LUC, which can be applied to advance mechanistic hypotheses for ES variations. The results of this study can inform sustainable management strategies by regulating ES interactions in watersheds.

Integrated approaches to nature-based solutions in Africa: Insights from a bibliometric analysis

The recognition of nature-based solutions (NbS) is on a growing trend worldwide in an era of climate change, and intensified demand for improved human health, better preparedness for disasters, food and water security. The solutions seek to restore, protect and sustainably manage natural and modified ecosystems to optimize biodiversity and human wellbeing benefits. In this study, a scientometric analysis of works indexed in Web of Science database until April 2022 was carried out to analyze 123 studies on NbS in Africa. The most active institutions, authors, and countries involved in publication on the topic and their evolution with time was assayed. African countries with exception of South Africa conducted limited research on the topic. About 38.2% of total searched outputs were affiliated to South African institutions. Most research output on the search query was in the environmental sciences and ecology subjects. A sluggish growth in research on the topic was established from the bibliographic coupling of authors and countries as well as keyword analysis. The study recommended for institution and policy overhaul, creation of NbS awareness and better financing of related projects to enhance the documentation and research on the topic in Africa by African researchers to supplement research already conducted by developed countries.

Linking human wellbeing and urban greenspaces: Applying the SoftGIS tool for analyzing human wellbeing interaction in Helsinki, Finland

This article reviews a study into the relationships between greenspaces and the benefits to psychological, social, and physical aspects of human wellbeing achieved through interaction in the Helsinki urban region in Finland. This relationship is theorized, analyzed, and measured through the transactional paradigm of affordance theory and is operationalized through the use of a public participation geographic information system (PPGIS) questionnaire, SoftGIS, which activated the urban greenspace–human wellbeinginteraction throughits map-based data collection. Over 1800 unique place–based relationships were statistically analyzed. Findings revealed that Helsinki’s greenspaces provided, overall, mostly physical and social wellbeing benefits; the psychological benefits such as reduction in stress and mental relaxation were not as frequent in these urban greenspace interactions. The results indicate multiple aspects of human wellbeing are supported by interaction with urban greenspaces of varying characteristics within the region but the urban greenspaces which provided the most human wellbeing benefits included large size, woodland typology, moderately maintained with loose or ‘wild’ vegetation, and few amenities such as benches and structures. The study’s implications include urban planning, public policy, and human health as well as insight into the multifunctional design and strategic management of greenspaces in urbanizing regions to provide continued and improved ecosystem services and benefits to humans and nature.

Bioactive Compounds and Therapeutics from Fish: Revisiting Their Suitability in Functional Foods to Enhance Human Wellbeing.

Global public awareness about fish-based diet and its health/nutritional benefits is on the rise. Fish nutritional profile projects promising bioactive and other compounds with innumerable health benefits for human wellbeing. As various reported researches involving fish/marine-derived molecules reveal promising attributes, and as the position of fish-based nutrients as nutraceuticals continue to strengthen, health challenges still confront communities worldwide, from cardiovascular disease, diabetes, and obesity to hypertension. Thus, further understanding of fish-based nutrient impact as functional foods remains crucial given the diverse prevailing compositional/nutraceutical merits. In this review, therefore, we provide important information regarding bioactive compounds and therapeutics obtained from fish, specific to the context of their suitability in functional foods to enhance human health. This contribution is hereby constructed as follows: (a) fish nutraceutical/therapeutic components, (b) constituents of fish-based nutrients and their suitability in functional foods, (c) fish antioxidant/bioactive compounds to help alleviate health conditions, (d) common human ailments alleviated by fish-based nutrients, and (e) role of fish in mental health and immune system. As increased fish consumption should be encouraged, the potential of the quality proteins, omega-3 fatty acids, and other compounds inherent in fish should steadily be harnessed.
