RESUMO

Changing the course of Earth's climate is increasingly urgent, but there is also a concurrent need for proactive stewardship of the adaptive capacity of the rapidly changing biosphere. Adaptation ultimately underpins the resilience of Earth's complex systems; species, communities, and ecosystems shift and evolve over time. Yet oncoming changes will seriously challenge current natural resource management and conservation efforts. We review forward-looking conservation approaches to enable adaptation and resilience. Key opportunities include expanding beyond preservationist approaches by including those that enable and facilitate ecological change. Conservation should not just focus on climate change losers but also on proactive management of emerging opportunities. Local efforts to conserve biodiversity and generate habitat complexity will also help to maintain a diversity of future options for an unpredictable future.

RESUMO

The environmental issue has become a global problem that needs to be examined frequently, motivating researchers to investigate it. Thus, the present study has investigated the asymmetric impact of natural resources, technological innovation, and globalization on the ecological footprint in the presence of environmental Kuznets curve (EKC) in Belt and Road Initiative (BRI) economies. This research divided the BRI economies into high income, middle-income, and low-income levels to capture income differences. The study has used annual time series data from 1990 to 2018. The study applied a novel Augmented Mean Group estimators method to calculate the robust and reliable outcomes. The findings show that natural resources drastically damage the environment quality, whereas technological innovations are helpful in reducing environmental degradation. Moreover, the result of the interaction term (natural resources and technological innovations) negatively impacts the ecological footprint. Interestingly, these findings are similar in the three income groups. In addition, globalization improves environmental quality in the middle-income BRI economies but reduces in high-income, low-income, and full sample countries. Furthermore, the Environmental Kuznets Curve (EKC) concept has been validated across all BRI economies. In line with these findings, several relevant policies are recommended for a sustainable environment in the BRI economies.

RESUMO

Models that are both spatially and temporally dynamic are needed to forecast where and when non-native pests and pathogens are likely to spread, to provide advance information for natural resource managers. The potential US range of the invasive spotted lanternfly (SLF, Lycorma delicatula) has been modeled, but until now, when it could reach the West Coast's multi-billion-dollar fruit industry has been unknown. We used process-based modeling to forecast the spread of SLF assuming no treatments to control populations occur. We found that SLF has a low probability of first reaching the grape-producing counties of California by 2027 and a high probability by 2033. Our study demonstrates the importance of spatio-temporal modeling for predicting the spread of invasive species to serve as an early alert for growers and other decision makers to prepare for impending risks of SLF invasion. It also provides a baseline for comparing future control options.

RESUMO

SignificanceResearch on innovation has two strands: institutions undertaking innovation as a research and development process and companies commercializing innovative products. We combine these strands, analyzing a sequence going from an innovation supply chain to a product supply chain from laboratory to market. We argue that these supply chains are symbiotic, and the relationship between entities is affected by economic considerations. Our framework allows an understanding of how research, regulatory policies, and economic conditions affect the emergence of innovations, the creation of institutions (markets, firms, contracts) to carry out these innovations, and the diffusion of the resulting products. Our approach may improve the design of strategies to induce climate change and food security solutions.

RESUMO

Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown etiology that affects the colon and rectum. It has evolved into a global burden due to the high incidence in developed countries and the highly-increased incidence in developing countries. Non-starch polysaccharides (NSPs) from natural resources, as a type of functional carbohydrates, have a significant therapeutic effect on UC because of their good anti-inflammatory and immunomodulatory activities. Based on the etiology and pathogenesis of UC, this review summarizes the intervention effects and mechanisms of NSPs in the prevention and treatment of UC. The results showed that NSPs can improve UC by protecting the intestinal mucosal barrier, regulating the immune response of the intestinal mucosa, and remodeling the intestinal flora and metabolites. These contents provide theoretical basis for the application of polysaccharides in the prevention and treatment of UC.

RESUMO

Ecotourism contributes to conserving natural resources and promoting natural and cultural resources stewardship. However, without the strong support and involvement of local people, it is not easy to achieve the stated goals. This study aimed to understand the local people's perception of the impacts and importance of ecotourism. We conducted a semi-structured interview of 167 respondents from Chitwan National Park (CNP), Nepal's prime center for ecotourism. The result revealed that more than 70% of respondents are interested in ecotourism activities, and their interests are significantly affected by their age, academic qualification, and occupation. Local people from the study area perceived that infrastructure development and increase in the knowledge base are significant impacts of ecotourism. The study showed that local people's socioeconomic and demographic characteristics significantly influenced their perceived impacts of ecotourism. Detailed understanding and consideration of socioeconomic and demographic characteristics can contribute to effective outreach and planning process, potentially resulting in the higher promotion of ecotourism.

RESUMO

In the Colombian context, disputes over natural resources, mainly over land, and poor governance are intertwined with armed conflict. Although efforts to address this situation, including the 2016 peace agreement signed between Colombian government and the Revolutionary Armed Forces of Colombia (FARC, by Spanish acronym) are underway, these disputes continue, affecting land use dynamics. Understanding the complexity and trends in land use conflicts, as well as the specific regional characteristics underlying differing land use changes across regions, is critical. This article aims to systematically understand land use dynamics in two contrasting and conflict-affected territories in Colombia, Caquetá and Cesar, thus identifying entry points to address land-use conflicts at the regional level. To address the complexity of each regional case, we apply a methodology based on system thinking to capture the interconnections between socio-economic and environmental system components and their land use dynamics. Results depicted through causal loop diagrams not just show the cascade of environmental, social, and economic failures resulting from land use changes in these two conflict-affected territories but also suggest that land tenure systems innovations and the promotion of sustainable land use interventions at the regional level can reverse the consequences of the land use changes. Thus, future actions addressing land use conflicts must be context-dependent, tackling the root and structural causes.

RESUMO

Deliberative processes are increasingly advocated as means to handle intractable natural resource management (NRM) conflicts. Research shows that disputing actors can deliberate and achieve higher degrees of mutual understanding and working agreements under ideal conditions, but the transferability of these findings to real-world intractable NRM conflicts can be questioned. This paper explores the possibilities of designing and realizing deliberation and its expected outcomes in real-world NRM conflicts. We used recommended design principles to set up deliberative processes in two intractable mining conflicts involving indigenous peoples in Northern Sweden and assessed the actors' communication and outcomes using frame analysis. The results show that the recommended design principles are hard, but not impossible, to fully implement in intractable NRM conflicts. Both conflicts proved difficult to deliberate and resolve in the sense of reaching agreements. However, the findings suggest that deliberation, as well as meta-consensus, or structured disagreement, is possible to achieve in settings with favorable conditions, e.g. good and established inter-group relations prior to the conflict. In the absence of these conditions, where relations were hostile and shaped by historical and institutional injustices, deliberation was not achieved. In both cases, polarization among the participants remained, or increased, in spite of the deliberative activities. The study highlights the importance of understanding deliberation as embedded in place specific historical and institutional contexts which shape both process and outcomes in powerful ways. More efforts should focus on alternative, or complementary, ways to handle intractable NRM conflicts, including how contested experiences of history, institutions and Indigenous rights can be addressed.

RESUMO

Our study explores the impact of financialization on carbon emissions by utilizing diverse financialization proxies, particularly for China. We examine the impact of financialization, institutional quality, globalization, natural resources, trade openness, and renewable and nonrenewable energy consumption on environmental pollution over the period 1996-2017 by utilizing dynamic autoregressive distributed lag (ARDL) simulations. The empirical findings of the study indicate that institutional quality, trade, globalization, natural resources, and renewable energy consumption significantly decrease environmental pollution in the long run, while foreign direct investment and financialization have neutral effects on carbon emissions. Our findings demonstrate that a 1% increase in institutional quality, trade, IFDI, renewable energy, and globalization leads to a decrease in CO2 emissions by 0.198, 0.016, 0.075, 0.010, and 0.072%, respectively. Even though financialization indexes contributed insignificantly to environmental degradation, other explanatory variables significantly affected carbon emissions through indirect effects of financialization. Financialization indexes behave in a similar context, and these proxy indicators are good parameters to understand the complex nature of financialization. Moreover, in order to achieve low carbon emissions and sustainable development, countries need viable financial institutions that focus on green growth by promoting clean production process strategies to ensure the reduction of CO2 emissions.

RESUMO

BACKGROUND: Local ecological calendars are ecocultural frameworks that link temporal and spatial scales, contributing to resilience and adaptive management of natural resources and landscapes. They also facilitate management, access and withdrawal of provisioning ecosystem services. In this article, we describe how the ecological calendar of the Kedayan people of Brunei Darussalam links skyscape and biodiversity with sociocultural aspirations to foster adaptive management of landscape, and provide an understanding of the transmission of calendric knowledge in the community. METHODS: In 2018, we collaborated with sixteen purposively sampled knowledge keepers from the Kedayan community of Brunei Darussalam to document the Kedayan local ecological calendar, and develop a calendrical pictogram. Using a structured questionnaire, we then interviewed 107 randomly selected community members, to understand the contemporary relevance and popularity of the Kedayan calendar, and the transmission of calendric knowledge in the community. RESULTS: Our findings reveal that very few respondents (n = 27, 25.3%) are aware of the existence of Kedayan ecological calendar; majority (n = 80, 74.7%) were not aware of its existence. There is no statistically significant correlation between consulting healers, knowledge on appropriate time requisite to consult healers, and awareness and self-professed knowledge of Kedayan calendar. Only 14 (13.1%) of the respondents reported to have received some form of calendric knowledge, while the majority (86.9%; n = 93) never received any calendric knowledge. Only a negligible 1.9% reported to have transmitted calendric knowledge to others indicating a breakdown in transmission of calendric knowledge. CONCLUSION: The calendric pictogram would help the community in revitalizing their calendar. However, the community will have to invest on enhancing transmission of calendric knowledge.

RESUMO

Linking human behavior to environmental quality is critical for effective natural resource management. While it is commonly assumed that environmental conditions partially explain variation in visitation to coastal recreation areas across space and time, scarce and inconsistent visitation observations challenge our ability to reveal these connections. With the ubiquity of mobile phone usage, novel sources of digitally derived data are increasingly available at a massive scale. Applications of mobile phone locational data have been effective in research on urban-centric human mobility and transportation, but little work has been conducted on understanding behavioral patterns surrounding dynamic natural resources. We present an application of cell phone locational data to estimate the effects of beach closures, based on measured bacteria threshold exceedances, on visitation to coastal access points. Our results indicate that beach closures on Cape Cod, MA, USA have a significant negative effect on visitation at those beaches with closures, while closures at a sample of coastal access points elsewhere in New England have no detected impact on visitation. Our findings represent geographic mobility patterns for over 7 million unique coastal visits and suggest that closures resulted in approximately 1,800 (0.026%) displaced visits for Cape Cod during the summer season of 2017. We demonstrate the potential for human-mobility data derived from mobile phones to reveal the scale of use and behavior in response to changes in dynamic natural resources. Potential future applications of passively collected geocoded data to human-environmental systems are vast.

RESUMO

Scenic resources can serve as symbols of a region's natural resources and culture and are often the stimulus for the development of national parks. Thus, careful scientific planning and effective management based on the identification and evaluation of scenic resources are key for the sustainable development of national parks. In this study, one object-oriented and three pixel-based (maximum likelihood classification, neural network, and support vector machine) classification methods were applied to identify scenic resources in Yesanpo National Park using high-resolution Gaofen-2 images. The classification accuracy of these scenic resources was evaluated through systematic sampling, which improved the objectivity and accuracy of the classification precision evaluation. All methods met the precision requirements of scenic resource identification, and the accuracy of object-oriented classification was the highest. The application scope of the different methods varies, and suitability can be determined according to the needs of scenic resource recognition. Collectively, this study has proposed an effective and practical method for the identification of scenic resources within Yesanpo National Park, which is of significance for its future planning and management. Moreover, this strategy can be applied by other national park planners to select areas for tourism development, formulate sustainable development strategies, and provide technical support and decision-making guidance for national park planning and management.

RESUMO

While knowledge of the ecological impacts of marine debris is continually advancing, methods to evaluate the comparative scale of these impacts are less well developed. In the case of costly environmental restoration in marine and coastal environments, quantifying and comparing the ecological impacts of diverse forms of ecosystem injuries can facilitate a more efficient selection of restoration projects. This article proposes evaluating marine debris removal projects in an ecological service equivalency analysis framework that can be used to compare marine debris removal to other types of environmental restoration. Drawing on existing spatial and temporal data with respect to marine debris impacts on habitats and resources, we demonstrate how resource managers and organizations involved in marine debris removal can quantify the ecological service benefits of a removal project and use it to comparatively select between projects based on present value ecological benefits. This valuation can be useful in natural resource damage assessment restoration selection, and for directing limited funds to marine debris removal projects which produce the greatest gains in ecological services. This ecological scaling framework is applied to a seagrass injury case study to demonstrate its application for scaling marine debris removal as compensatory restoration.

RESUMO

Trust is a key variable for successful natural resource management and is commonly the focus of conceptual and methodological development. Distrust, on the other hand, is frequently cited as an obstacle to management, but appears to be rarely defined, conceptually underdeveloped, and inconsistently examined. This systematic review protocol (OSF preregistration https://doi.org/10.17605/OSF.IO/GKUAW) was developed to answer two primary questions in relation to protected area and natural resource management: 1) How is distrust conceptualized, and 2) What methods are used to gather evidence of distrust? The aim is to provide a comprehensive overview of how distrust is theoretically developed and what questions are used to uncover distrust. Also, it will summarize findings on what leads to and results from distrust. Four academic and eight gray literature databases will be searched using Boolean keyword searches. Articles eligible for inclusion are those that present original research, gather and present evidence of distrust, and focus on protected areas and/or natural resource management. The review will result in a narrative synthesis that summarizes approaches to distrust within protected area and natural resource management.

RESUMO

Hyperlipidemia is a chronic metabolic disease caused by the abnormal metabolism of lipoproteins in the human body. Its main hazard is to accelerate systemic atherosclerosis, which causes cerebrovascular diseases such as coronary heart disease and thrombosis. At the same time, although the current hypolipidemic drugs have a certain therapeutic effect, they have side effects such as liver damage and digestive tract discomfort. Many kinds of polysaccharides from natural resources possess therapeutic effects on hyperlipidemia but still lack a comprehensive understanding. In this paper, the research progress of natural polysaccharides on reducing blood lipids in recent years is reviewed. The pharmacological mechanisms and targets of natural polysaccharides are mainly introduced. The relationship between structure and hypolipidemic activity is also discussed in detail. This review will help to understand the value of polysaccharides in lowering blood lipids and provide guidance for the development and clinical application of new hypolipidemic drugs.

RESUMO

Over the past decades, wildfire has imposed a considerable cost on natural resources and human lives. In many regions, annual wildfire trends show puzzling oscillatory patterns with increasing amplitudes for burned areas over time. This paper aims to examine the potential causes of such patterns by developing and examining a dynamic simulation model that represents interconnected social and natural dynamics in a coupled system. We develop a generic dynamic model and, based on simulation results, postulate that the interconnection between human and natural subsystems is a source of the observed cyclical patterns in wildfires in which risk perception regulates activities that can result in more fire and development of vulnerable properties. Our simulation-based policy analysis points to a non-linear characteristic of the system, which rises due to the interconnections between the human side and the natural side of the system. This has a major policy implication: in contrast to studies that look for the most effective policy to contain wildfires, we show that a long-term solution is not a single action but is a combination of multiple actions that simultaneously target both human and natural sides of the system.

RESUMO

Globalization as well as the ratio of ageing people in the group of 11 (G-11) countries has seen a rapid increase in recent years. Therefore, this study aims to provide effective policy recommendations for sustainable development goals 13, 8, and 7, for the G-11 countries. This work estimates the impact of natural resources and the ageing population on the emission of carbon dioxide (CO2) in G-11 countries using panel data from 1990-2020. For empirical results, second-generation methods were applied. The Westerlund co-integration test that assesses co-integration confirms the firm association among the parameters, and the values of coefficient of the cross-sectional autoregressive distributed lag (CS-ARDL) approach show that a 1% increase in the ageing population will lower the emissions of CO2 by 13.41% among G-11 countries. Moreover, the findings show that there exists an environmental Kuznets curve (EKC) among natural resources, globalization, economic growth, ageing people, and the emission of CO2. Based on the findings, this work presents some important policy implications for achieving sustainable growth in the G-11 countries. These countries need to lower the amount of energy obtained from fossil fuels to improve air quality.

RESUMO

Enzyme catalysts are an integral part of green chemistry strategies towards a more sustainable and resource-efficient chemical synthesis. However, the use of biocatalysed reactions in retrosynthetic planning clashes with the difficulties in predicting the enzymatic activity on unreported substrates and enzyme-specific stereo- and regioselectivity. As of now, only rule-based systems support retrosynthetic planning using biocatalysis, while initial data-driven approaches are limited to forward predictions. Here, we extend the data-driven forward reaction as well as retrosynthetic pathway prediction models based on the Molecular Transformer architecture to biocatalysis. The enzymatic knowledge is learned from an extensive data set of publicly available biochemical reactions with the aid of a new class token scheme based on the enzyme commission classification number, which captures catalysis patterns among different enzymes belonging to the same hierarchy. The forward reaction prediction model (top-1 accuracy of 49.6%), the retrosynthetic pathway (top-1 single-step round-trip accuracy of 39.6%) and the curated data set are made publicly available to facilitate the adoption of enzymatic catalysis in the design of greener chemistry processes.

RESUMO

Under the pressure of environmental crisis caused by production and economic development, a policy for Leading Officials' Accountability Audit of Natural Resources (LOAANR) was issued in 2014 to reduce the environmental risks and gain high-quality economy. Taking LOAANR policy as the research object, and based on 2011 to 2018 panel data from Chinese heavy-polluting enterprises, this paper employed a two-way fixed difference-in-differences (DID) model to explore the relationship between the LOAANR, environmental costs (ECs) and green innovation (GI). It was found that the implementation of the LOAANR significantly promoted enterprise GI, with the regulating impact mechanism, EC. GI efficiency was measured by continuous DID method. A heterogeneity analysis revealed that non-state-owned enterprises (NSOEs) were more eager to environmentally innovate. A corporate life cycle heterogeneity analysis of the GI policy effect found that the policy effect was negative in the decline stages. Compared with the eastern Chinese enterprises, enterprises in other regions were found to be more prone to positively adopting GI to maximize benefits in the face of the LOAANR. The policy was observed to have inhibited GI in central Chinese enterprises. It was also demonstrated that the policy effect has time and regional dynamic effect. Common trend, placebo, PSM-DID tests, and another robustness regressions were applied to support the conclusions. All the findings are expected to provide basic theoretical guidance for more environmental policies and high-quality production.

RESUMO

Depletion of natural resources and population aging are the two most critical challenges for environmental sustainability. However, the research that integrates natural resources and population aging in the same environmental policy framework is still scant. Therefore, this study investigates the linkage between natural resources, population aging, green technologies, and ecological footprint (EF) of G7 countries. In addition, this study also explores the moderating effects of green technologies on the relationship between natural resources and EF. Drawing on the panel times series data from 1970 to 2017, we employ a cross-sectional autoregressive distributed lags (CS-ARDL) model for short- and long-run empirical estimation. Our empirical analysis indicates that natural resource use exacerbates ecological degradation by increasing EF. By contrast, population aging and green technologies present positive ameliorative effects on EF. Interestingly, the interaction effect of green technologies and natural resources indicates that the damage to ecological quality from natural resources can be effectively improved by means of green technologies, thus maintaining environmental sustainability. Furthermore, the results of panel quantile regression show that the effects of population aging and green technologies on the overall ecological footprint distribution in G7 countries are heterogeneous, while the effects of natural resources on the distribution of all conditions of the ecological footprint are positive. In addition, this paper verifies the causal relationship between the variables using the Dumitrescu and Hurlin test. The findings reveal that the relevant changes in all explanatory variables are bilaterally causally associated with EF. Based on these results, this paper provides some feasible policy recommendations.
