RESUMEN

The landscape in southwestern Ghana faces rampant modification due to socio-economic activities, posing threats to ecosystem service provision and environmental sustainability. Addressing these threats involves empowering land-use actors to design landscapes that offer multiple benefits concurrently. This study employs a geodesign framework, integrating participatory ecosystem service assessment and spatial simulations. This geodesign framework aims to design the landscape in a collaborative manner in a way that supports multiple benefits concurrently, mitigating the threats posed by landscape modification. Reflecting on local land-use perceptions during a workshop, we developed land-use options and land management strategies based on selected land-cover types. We identified urban greens, open space restoration, rubber mixed-stands, mangrove restoration, selective-cutting land preparation, soil conservation, and relay cropping as land-use options to target selected land-cover types of shrubland, cropland, smallholder rubber, smallholder palm, wetland, and settlement. The land management strategies translated into landscape scenarios based on local need conditions. We generated the local need conditions which translated into the landscape scenarios by reflecting on the location of land-cover types, 'change-effect' conditions within rubber, settlement, and cropland, and 'no-change'conditions within cropland. Results indicate synergies between the created landscape scenarios and ecosystem service provisioning, with 'no-change' within cropland providing the highest synergy and 'change-effect' within rubber providing the least synergy. Spatial modeling of local perceptions forms the novelty of this study, as the fusion of participatory assessments and spatial modeling allows for a more holistic understanding of the landscape, its services, and the potential implications of different management strategies. The geodesign framework facilitated the design of the complex heterogeneous landscape to visualize possibilities of maximizing multiple benefits and can be used for future planning on the landscape.

RESUMEN

In the arid southwestern U.S., urban greening strategies have been promoted to alleviate ecosystem disservices associated with lawns, including the adoption of xeric yards with desert-adapted floras and gravel groundcover and wildlife-friendly yards with complex vegetation structure and composition. Scant studies have investigated the extent of different vegetation changes in urban greening practices and the complexity of associated human drivers. We addressed this gap by analyzing survey data from two survey periods (2017 and 2021) to answer the following questions: to what extent have residents from metropolitan Phoenix made different vegetation changes in their yards over the last decade, and how do multi-scalar human drivers affect different vegetation changes? We found a sustainable trajectory for residential vegetation changes in Phoenix since mid-2010s, with declining additions of grass and increases in trees and desert plants across residential neighborhoods. Esthetics was an influential driver of both tree planting and native gardening. Additionally, tree planting was associated with anthropocentric values (i.e., low-maintenance needs), while desert plant additions reflected the appreciation of nature (i.e., attitudes towards the desert) and environmental concerns (i.e., supporting wildlife). Institutions such as local government programs might shape residents' vegetation choices, as tree planting differed among municipalities. We also found counterintuitive influences of residential tenure controls on landscaping decisions. Specifically, renters were more likely to add yard trees compared to homeowners. Our results inform landscape sustainability by identifying potential pathways to residential yard changes that offer a multitude of services while being appreciated and maintained by residents.

RESUMEN

Ecosystem services (ESs) play vital roles in meeting the needs of human well-being and supporting sustainable development. However, there is limited research on how the types, amounts, interactions, and changes of the ESs collectively impact human well-being under the context of sustainable development goals (SDGs) of the United Nations. This study selected Qinghai Province of China as the study area and intended to make such an attempt to fill this gap in terms of the following aspects: (1) analyzing the spatial patterns and changing trends of ten ESs (food supply, water supply, carbon sink, soil retention, sand fixation, hydrological regulation, flood mitigation,cultural service,net primary productivity, and habitat quality) in Qinghai Province from 2000 to 2018; (2)constructing a multi-level index system of human well-being under the framework of the SDGs, and setting the criteria to assess the level of local human well-being; and (3) building a structural equation model to explore the direct and indirect impacts of the types, amounts, interactions and changes of the ESs on actual human well-being and the gaps between actual and targeted human well-being. The findings revealed that: (1) most of the ecosystem services fluctuated with significant downward or upward trends during 2000-2018, except for four ESs (i.e., carbon sink, soil retention, flood mitigation, and habitat quality); (2) only a few indicators of local residents' well-being such as meat production, milk production, the numbers of medical technical personnel in hospitals and health centers, and the numbers of scientific and technical personnel met the SDG criteria in most time, while other indicators remained at low levels and there were large gaps between them and the SDG criteria; (3) actual human well-being and the gaps between actual and targeted human well-being were affected by the types, amounts, interactions and changes of the ESs with different degrees directly or indirectly. The approaches and results in this study are instructive for other regions of the world to make certain the roles of ESs in promoting human well-being and substantiating the SDGs.

RESUMEN

Ecological restoration is an important approach to improving landscape sustainability. However, ecological restoration in drylands is strongly limited by water resources. Therefore, a technical route for ecological restoration in drylands that creates sustainable landscapes based on those water constraints is needed. In this study, we develop a spatially explicit framework named "Constraint-Pattern-Benefit" to plan ecological restoration patterns in Inner Mongolia, China. Based on a prediction of the ecosystem service (ES) increase under limited evapotranspiration as a water constraint, we constructed 5 landscape sustainability-related strategies with 100 ecological restoration scenarios, which considered fragmentation of restoration locations, distance to city, water consumption, and the allocation scale to determine the spatial arrangement of ecological restoration. Results show that the ES increase potential of ecological restoration under water constraints is distributed in the center of Inner Mongolia. The multi-objective scenario simultaneously achieves 59.1% water yield, 74.2% soil conservation, 57.2% sand fixation, and 52.8% carbon sequestration with 50% restored landscape. Considering the indicators of fragmentation, water consumption, and distance to city decreases the restored landscape fragmentation from 0.44 to 0.26, improves the restoration efficiency by 14.41%, and increases the beneficiary population by 35.5%, respectively. Small-scale allocation can further increase the ES realization efficiency, which is on average 4.8% higher at the city scale than at the provincial scale. Moreover, this approach focuses on the sustainable effect of the spatial arrangement on dryland landscapes at different scales, which provides methodological support for improving the sustainability of drylands.

RESUMEN

Urban ecosystem services (UES), as an important concept in nature-based solutions, can effectively mitigate adverse environmental burdens and have great potential in addressing environmental justice issues. However, few studies linking UES with environmental justice have considered both supply and demand sides of UES, particularly at the spatial scale of residential walking space. Against this backdrop, we investigated the distributional justice of supply and demand for urban cooling, flood mitigation, air purification, and outdoor recreation in residential walking spaces in Shanghai among socially vulnerable groups (i.e., elderly residents, children, females, low-income residents, no-hukou residents, and ethnic minorities). We found that (1) the UES supply of residential walking space was much lower than that of non-residential walking space, while the UES demand was much higher than that of non-residential walking space. (2) Higher proportions of ethnic minorities, no-hukou residents, and females in Shanghai were positively correlated with several UES demands but were not positively correlated with ES supply, indicating a higher possibility of unsatisfied UES demand for these disadvantaged groups. Future urban blue-green space planning should pay more attention to the spatial allocation of blue-green space, especially placing more blue-green space around residential walking spaces with high UES demand and with a high proportion of socially disadvantaged groups.

RESUMEN

Globally, shifting cultivation is known to be an important driver of tropical deforestation. However, in this paper, we argue that it can be sustainably managed if the environmental boundary conditions, laid by the traditional customs and practices, are fully respected. We narrate an empirical study from the Zunheboto district of Nagaland, India, where we deployed a mixed research method to explore the Indigenous and Local Knowledge and Practices (ILKPs) associated with shifting cultivation (aka Jhum), particularly concerning farm-level practices, forest and biodiversity conservation, and disaster risk reduction measures. The research method included analysis of primary data obtained through Focus Group discussions (FGDs), key informant interviews (n = 21), and a questionnaire survey (n = 153) with Jhum farmers from two different age groups, i.e., below 50 years (middle-aged farmers) and above 50 years (older farmers). From the qualitative inquiry, we identified 15 ILKPs, which were then validated from survey responses. We used the Mann-Whitney U test to examine differences in agreement between two groups of framers. Based on this analysis, we conclude that upholding of the ILKPs holds strong potential for the local implementation of several Sustainable Development Goals (SDGs), particularly, SDG-1(No poverty), SDG-2 (Zero hunger), and SDG-15 (Life on land). However, eight of the identified ILKPs showed a statistically significant difference between older and middle-aged farmers, underlining a declining trend. Finally, we suggest suitable policy measures to mainstream ILKPs to balance the trade-offs in food production and biodiversity conservation, and to ensure the future sustainability of Jhum cultivation in the region and beyond.

RESUMEN

The Mongolian Plateau, home to the world's largest contiguous temperate grasslands, has been known for its vast steppe landscapes and legendary history of the Mongol Empire. However, like temperate grasslands elsewhere around the world, the Mongolian steppe landscapes have been severely degraded by increasing human activities during the past several decades. The main objective of this study was to assess the landscape and ecosystem changes in the Wulagai River Basin (WRB) in Inner Mongolia, where China's last intact steppe ecosystem reportedly resides. Using remote sensing data and landscape metrics, we found that, during 1979-2016, WRB lost about 55 % of wetlands, 76 % of shrublands, and 46 % of sandy-land vegetation, with its most dominant vegetation type shifting from meadow steppe to dry steppe for the first time in history. Human land uses continued to intensify: cropland expanded by about 40 %; impervious surface area increased by almost 34 times; and surface coal mining rampaged through the heartland, tearing up vegetation and sucking up water near and far. The WRB landscape became more diverse compositionally (increasing land cover types), more fragmented ecologically (habitat loss and isolation), and more complex geometrically (anthropogenic and natural landscape elements entangled). Damming, mining, and overgrazing were the major direct drivers for the observed environmental changes. Government-sponsored restoration programs have had positive ecological changes across China, but landscape destruction and fragmentation in the Wulagai River Basin have continued. This dire situation demands urgent government policy intervention and stakeholder-involved governance actions to promote the sustainability of this legendary landscape.

RESUMEN

Local regulations on residential landscapes (yards and gardens) can facilitate or constrain ecosystem services and disservices in cities. To our knowledge, no studies have undertaken a comprehensive look at how municipalities regulate residential landscapes to achieve particular goals and to control management practices. Across six U.S. cities, we analyzed 156 municipal ordinances to examine regional patterns in local landscape regulations and their implications for sustainability. Specifically, we conducted content analysis to capture regulations aimed at: 1) goals pertaining to conservation and environmental management, aesthetics and nuisance avoidance, and health and wellbeing, and 2) management actions including vegetation maintenance, water and waste management, food production, and chemical inputs. Our results reveal significant variation in local and regional regulations. While regulatory goals stress stormwater management and nuisance avoidance, relatively few municipalities explicitly regulate residential yards to maintain property values, mitigate heat, or avoid allergens. Meanwhile, biological conservation and water quality protection are common goals, yet regulations on yard management practices (e.g., non-native plants or chemical inputs) sometimes contradict these purposes. In addition, regulations emphasizing aesthetics and the maintenance of vegetation, mowing of grass and weeds, as well as the removal of dead wood, may inhibit wildlife-friendly yards. As a whole, landscaping ordinances largely ignore tradeoffs between interacting goals and outcomes, thereby limiting their potential to support landscape sustainability. Recommendations therefore include coordinated, multiobjective planning through partnerships among planners, developers, researchers, and non-government entities at multiple scales.

RESUMEN

Enhancing crop diversification in intensive fields has the potential to increase crop yield and reduce environmental footprint. However, these relationships at the landscape scale remained unclear in intensive farming. Addressing this gap, this paper aims to elucidate how crop yield, resources use efficiency (RUE), and environmental footprint (EF) vary with crop diversification levels in the North China Plain. Management practices, including crop pattern, field size, and agronomic inputs, were collected for 421 landscapes of 1 × 1 km subplots using Sentinel-2 and Landsat-8 images and survey. The results showed that, at the landscape scale, energy and fertilizer contributed over 53 %, and 37 % of the carbon footprint, respectively. N fertilizer constituted >98 % of the nitrogen footprint. P fertilizer accounted for over 80 %, while electricity comprised >13 % of the phosphorus footprint. Compared with simplified landscapes, diversified landscapes exhibited several significant features: 1) 56 % reduction of the area ratio of winter wheat-summer maize double crop pattern (WM), 2) a significant decrease in field size, 3) the decreased use of total NPK fertilizers at 32 %, 30 %, and 30 %, respectively, 4) the increased inputs of irrigation water, diesel, electricity, pesticide and labour at 21 %, 19 %, 21 %, 77 %, and 92 %, respectively. Although yield could be reduced at 33 % when transforming simplified landscapes into moderately diversified ones, they increased with the further promotion of crop diversification. Thus, the diversified landscapes could achieve a balance in yield, RUE, and EF to enhance sustainability, whereas simplified landscapes can similarly achieve a balance to benefit productivity. We emphasize the viable potential of diversified landscapes to enhance sustainable agricultural development by optimizing crop composition. This analysis offers pioneering evidence of landscape-scale agronomic and environmental performances of crop diversification.

RESUMEN

Nature-based solutions (NBS) have great potential for achieving urban sustainability. While several reviews have comprehensively examined NBS, few have focused on its role in addressing urban sustainability challenges. Here we present a systematic review of 142 case studies selected from English papers published in SCI journals (i.e., indexed by Web of Science) during 2016-2022, whose titles, abstracts or keywords contain both urban-related terms and NBS-related terms. Using multiple methods, including statistical analysis, deductive content analysis, and inductive content analysis, we found that: (1) NBS have primarily been utilized to address urban flooding (43 %) and heat stress (21 %), with green roofs (24 %) and urban forests (16 %) being the most extensively studied NBS for tackling these challenges. (2) The ecosystem services (ES) capacity of NBS has been heavily researched (57 %), while studies addressing ES flows (7 %) and ES demand (18 %) are limited. (3) Most studies involved at least one NBS implementation process (83 %), but primarily focused on selecting and assessing NBS and related actions (66 %), with fewer studies on designing and implementing NBS and transferring & upscale NBS. We suggest that future research should contribute to the establishment of a checklist to assist in identifying which NBS types are effective in addressing specific urban sustainability challenges in varying contexts. Integrating the science and practice of NBS for urban sustainability is also crucial for advancing this field.

RESUMEN

There is an urgent demand for substantial reforms in the governance of coastal regions. Recent research advocates for a transformative shift in European coastal governance system towards a landscape governance approach. This perspective, informed by a narrative literature review on coastal and landscape governance, explores the potential value of coastal landscape governance, drawing on the Council of Europe Landscape Convention. Our results, presented in the form of a manifesto, underscore the need to move beyond political administrative boundaries and address all coastal landscapes as socio-ecological systems. It emphasises the necessity for the State to recognise them as a public and common good, establishing a specific governance arena with dedicated actors and institutions. The manifesto also advocates for landscape justice through knowledge co production, urging transformative change and landscape based regional design to envision alternative futures. Additionally, it calls for regionalising coastal landscape governance and invites scholars from other transdisciplinary and interdisciplinary perspectives to contribute to this research agenda.

RESUMEN

Context: Urbanization is rapidly increasing worldwide, with about 60% of the global population currently residing in cities and expected to reach 68% by 2050. In Latin America's tropical Andes region, managing these changes poses challenges, including biodiversity loss and vulnerability to climate change. Objectives: This study assesses urban growth and agricultural intensification impacts on the ecological functionality of metropolitan green infrastructures and their capacity to provide ecosystem services using a landscape sustainability and sociometabolic approach. Specifically, it aims to identify landscape configurations promoting socio-ecological sustainability amidst rapid urbanization. Methods: A landscape-metabolic model (IDC) was applied to evaluate the interactions between land use changes and ecosystem functions in the metropolitan region of Cali. Results: Agricultural intensification and industrialization, coupled with uncontrolled urban growth, have significantly transformed the landscape, posing threats to its sustainability. The prevailing biocultural landscapes hold a substantial potential to provide essential ecosystem services to the metropolis. The IDC offers an approach that utilizes a land cover map and agricultural production/metabolism data to calculate an indicator closely related to ecosystem services and multifunctionality. Conclusions: The IDC model stands out for efficiently capturing landscape dynamics, providing insights into landscape configuration and social metabolism without extensive resource requirements. This research highlights the importance of adopting a landscape-metabolic and green infrastructure framework to guide territorial policies in the tropical Andes and similar regions. It stresses the need for informed land use planning to address challenges and leverage opportunities presented by biocultural landscapes for regional sustainability amidst rapid urbanization and agricultural expansion.

RESUMEN

Context: Zoos are a unique landscape with fascinating connections to the principles of landscape ecology. These 'zooscapes' have a focus on managing wild species. Objectives: This article examines the multiple scales of zoos as urban green spaces, exhibit landscapes, and resources for resilience. I identify that landscape ecology can inform zoo evolution and note how zoos may provide a novel research site for landscape ecology. Methods: I provide a brief history of American zoos and insight into lingering questions within zoos, including their representations of animals and humans. Additionally, I note conceptual overlap between zoo design/function and landscape ecology literature. Results: Zoos provide habitat for native species and valued cultural ecosystem services. Zoo exhibits developed a landscape focus as modern landscape ecology emerged in the 1980s. Patches, corridors, and matrices exist within a zoo, and these facilities have value for the genetic support of fragmented populations. Zoos' strategies for disease management are increasingly relevant for global health. Simultaneously, zoos must exhibit sustainable landscapes, not just ecological simulacrums for threatened species. Conclusions: Zoos must promote humanity's continued coexistence with other species. A landscape view is essential to achieving this goal. Zoos need to model sustainable landscapes of our present and future.

RESUMEN

Recent studies have shown that the relationships between ecosystem services (ES) and human wellbeing (HWB) can be positive, negative, or non-existent, but the underlying causes and processes remain unclear. This study aimed to investigate how and why the local level ES-HWB relationship would change geospatially and manifest on broad regions. Using data for Mainland China, we first calculated seven ES and Human Development Index (an indicator of HWB), then used geographically weighted regression and cluster analysis to quantify the county-level ES-HWB relationship, and finally adopted Wilcoxon test and random forest to investigate key influencing factors. We found that (1) the local-scale relationship between ES and HWB exhibited a great deal of spatial heterogeneity, varying from positive to negative or no correlations across broad regions; (2) the varying relationships merged spatially into three general types of regions: Positive Correlation-Dominant Region, Negative Correlation-Dominant Region, and No Correlation-Dominant Region; and (3) the variations and spatial patterns of the ES-HWB relationships were influenced by a number of social-ecological factors (e.g., population density and land cover compositions), and generally corresponded to different stages of land use transition and socioeconomic development: a positive ES-HWB relationship was found mainly in socioeconomically underdeveloped (rural or agricultural) regions with low ES production levels; a negative ES-HWB relationship occurred mostly in intermediately developed regions with abundant non-food ES; and ES and HWB had no relationships in socioeconomically well-developed (intensive agriculture/urbanized) societies with ample provisioning ES. These findings suggest that neither the "environmentalist's paradox" nor the "environmentalist's expectation" adequately accounts for the complexity of the ES-HWB relationship.

RESUMEN

In regional sustainability evaluation and policy analysis, the paradigm of safe operating spaces (SOS) has been widely applied. Yet, SOS is not readily useful for informing policy interventions toward sustainability transition. This study reports on a methodological framework that operationalizes SOS at the regional scale for designing spatially targeted sustainability interventions. In particular, this framework accounts for teleology by integrating policy orientations of the place-variant "major function" of development, and provides early-warnings by integrating long-term social-environmental trends. The framework we proposed has been applied by the Chinese government in a coastal province (Liaoning) for a landscape sustainability project, which is introduced here step-by-step. The four main steps include: (1) Quantifying SOS status across multiple "what to sustain" dimensions, e.g., land scarcity, water scarcity, pollutant discharge, and ecosystem health for the inland, and coastal exploitation intensity, marine environmental quality, and marine ecosystem biodiversity for the sea. (2) Quantifying SOS status in terms of the place-variant "what to develop" dimensions, e.g., urbanization-oriented, agriculture-stock-oriented, versus conservation-oriented development. (3) Integrating the two as a composite indicator of three ordinal levels to classify the current SOS status. (4) Developing a multi-level sustainability early-warning system by cross-analysis of the SOS status and social-environmental interaction trends (e.g., changes in, e.g., resource utilization efficiency, pollutant discharge, and eco-environmental quality). The potential use of the framework is demonstrated through the case of Liaoning Province, China, which helps policy-makers to identify priority areas for sustainability interventions. Methodological robustness and future directions of applying this multi-level sustainability early-warning system are further discussed.

RESUMEN

The provision of ecosystem services is inherently spatial. Landscape structure affects service provision through multiple landscape-level processes, such as fragmentation, edge and connectivity effects. These processes can affect areas of ecosystem service supply and demand, and the flows linking those areas. Despite the emergence of sophisticated spatial ecosystem service assessments in the last two decades, we show through a literature review that landscape-level processes are still rarely considered in a comprehensive way. Even when they are considered, landscape effects are mostly limited to landscape composition, and configuration effects are underrepresented. Furthermore, most studies infer ecosystem service provision by only evaluating supply, ignoring demand and flows. Here we present a simple conceptual framework that illustrates how to incorporate landscape-level processes in the assessment of the different components of the service provision chain (supply, demand and flows). Using simulations, we evaluated how estimations of ecosystem service provision change when considering different landscape processes and discussed the implications of disregarding landscape effects. However, to fully implement the framework, a series of challenges linked to mapping and quantifying supply and demand, defining adequate scales of analysis, measuring flows, and parameterizing models for different types of services, still need to be overcome. To promote an adequate use and management of ecosystem services, it is essential to better incorporate landscape processes in ecosystem service assessments. This will lead to more quantitatively accurate and spatially precise estimates.
