Sustainable land use and management research: a scientometric review
ContextThe study of sustainable land use reflects the interdisciplinary characteristics of land science, geography, ecology and sustainability science. In recent years, research on sustainable land use has rapidly increased in scope and speed around the world.ObjectivesTo discuss the trends, research power distribution, key areas, research hotspots and international cooperation in sustainable land use research in the past 20 years.MethodsThis paper used the Bibliometrix and Biblioshiny software packages to entire process of bibliometric analysis and visual display of sustainable land use research papers from 1990 to 2019 (data update time is May 10, 2019).Results(1) The amount of publications in the field of sustainable land use from 1990 to 2019 increased with time and entered a period of rapid growth after 2013. (2) From the perspective of research power, the influence of developed countries in the field of sustainable land use is significantly stronger than that of developing countries. (3) Through high-frequency keyword analysis, land use change, land degradation, and sustainable land management are hotspots in the field of sustainable land use. (4) The themes of sustainable land use have changed greatly in various periods, and some of the themes have strong continuity.ConclusionsIn order to promote the development of sustainable land use, this paper proposes to integrate strong sustainability theory, landscape ecology theory, and geographical design concepts into this field, thereby greatly expanding the theoretical space. Also, this paper proposes to improve the scientificity of the evaluation indicators and use emerging technologies to timely monitor the status and evolution of land use, which can provide scientific basis and decision-making reference for the formulation of sustainable land use strategies, policies, and countermeasures.

Suprarural : architectural atlas of rural protocols of the American Midwest and the Argentine Pampas
The Atlas of rural protocols in the American Midwest and the Argentine Pampas is structured along eight systems of organization: transport and infrastructure, land subdivision, agricultural production, water management, storage and maintenance, human habitation, animal management, land management. Each of these systems possesses a number of organizational types, material components, normative relationships, and spectra of performance, which become available through a manual of instructions for a Suprarural architectural environment. The research is based on a realistic-overriding ethics towards design that operates by abstracting and intensifying unexplored territorial phenomena.

Land-use intensity alters networks between biodiversity, ecosystem functions, and services
Land-use intensification can increase provisioning ecosystem services, such as food and timber production, but it also drives changes in ecosystem functioning and biodiversity loss, which may ultimately compromise human wellbeing. To understand how changes in landuse intensity affect the relationships between biodiversity, ecosystem functions, and services, we built networks from correlations between the species richness of 16 trophic groups, 10 ecosystem functions, and 15 ecosystem services. We evaluated how the properties of these networks varied across land-use intensity gradients for 150 forests and 150 grasslands. Land-use intensity significantly affected network structure in both habitats. Changes in connectance were larger in forests, while changes in modularity and evenness were more evident in grasslands. Our results show that increasing land-use intensity leads to more homogeneous networks with less integration within modules in both habitats, driven by the belowground compartment in grasslands, while forest responses to land management were more complex. Land-use intensity strongly altered hub identity and module composition in both habitats, showing that the positive correlations of provisioning services with biodiversity and ecosystem functions found at low land-use intensity levels, decline at higher intensity levels. Our approach provides a comprehensive view of the relationships between multiple components of biodiversity, ecosystem functions, and ecosystem services and how they respond to land use. This can be used to identify overall changes in the ecosystem, to derive mechanistic hypotheses, and it can be readily applied to further global change drivers.

Detecting, Analyzing, and Predicting Land Use/Land Cover (LULC) Changes in Arid Regions Using Landsat Images, CA-Markov Hybrid Model, and GIS Techniques
Understanding the change dynamics of land use and land cover (LULC) is critical for efficient ecological management modification and sustainable land-use planning. This work aimed to identify, simulate, and predict historical and future LULC changes in the Sohag Governorate, Egypt, as an arid region. In the present study, the detection of historical LULC change dynamics for time series 1984–2002, 2002–2013, and 2013–2022 was performed, as well as CA-Markov hybrid model was employed to project the future LULC trends for 2030, 2040, and 2050. Four Landsat images acquired by different sensors were used as spatial–temporal data sources for the study region, including TM for 1984, ETM+ for 2002, and OLI for 2013 and 2022. Furthermore, a supervised classification technique was implemented in the image classification process. All remote sensing data was processed and modeled using IDRISI 7.02 software. Four main LULC categories were recognized in the study region: urban areas, cultivated lands, desert lands, and water bodies. The precision of LULC categorization analysis was high, with Kappa coefficients above 0.7 and overall accuracy above 87.5% for all classifications. The results obtained from estimating LULC change in the period from 1984 to 2022 indicated that built-up areas expanded to cover 12.5% of the study area in 2022 instead of 5.5% in 1984. This urban sprawl occurred at the cost of reducing old farmlands in old towns and villages and building new settlements on bare lands. Furthermore, cultivated lands increased from 45.5% of the total area in 1984 to 60.7% in 2022 due to ongoing soil reclamation projects in desert areas outside the Nile Valley. Moreover, between 1984 and 2022, desert lands lost around half of their area, while water bodies gained a very slight increase. According to the simulation and projection of the future LULC trends for 2030, 2040, and 2050, similar trends to historical LULC changes were detected. These trends are represented by decreasing desert lands and increasing urban and cultivated newly reclaimed areas. Concerning CA-Markov model validation, Kappa indices ranged across actual and simulated maps from 0.84 to 0.93, suggesting that this model was reasonably excellent at projecting future LULC trends. Therefore, using the CA-Markov hybrid model as a prediction and modeling approach for future LULC trends provides a good vision for monitoring and reducing the negative impacts of LULC changes, supporting land use policy-makers, and developing land management.

Assessing the homogenization of urban land management with an application to US residential lawn care
Changes in land use, land cover, and land management present some of the greatest potential global environmental challenges of the 21st century. Urbanization, one of the principal drivers of these transformations, is commonly thought to be generating land changes that are increasingly similar. An implication of this multiscale homogenization hypothesis is that the ecosystem structure and function and human behaviors associated with urbanization should be more similar in certain kinds of urbanized locations across biogeophysical gradients than across urbanization gradients in places with similar biogeophysical characteristics. This paper introduces an analytical framework for testing this hypothesis, and applies the framework to the case of residential lawn care. This set of land management behaviors are often assumed—not demonstrated—to exhibit homogeneity. Multivariate analyses are conducted on telephone survey responses from a geographically stratified random sample of homeowners (n = 9,480), equally distributed across six US metropolitan areas. Two behaviors are examined: lawn fertilizing and irrigating. Limited support for strong homogenization is found at two scales (i.e., multi- and single-city; 2 of 36 cases), but significant support is found for homogenization at only one scale (22 cases) or at neither scale (12 cases). These results suggest that US lawn care behaviors are more differentiated in practice than in theory. Thus, even if the biophysical outcomes of urbanization are homogenizing, managing the associated sustainability implications may require a multiscale, differentiated approach because the underlying social practices appear relatively varied. The analytical approach introduced here should also be productive for other facets of urban—ecological homogenization.

Simulating land use change for sustainable land management in rapid urbanization regions: a case study of the Yangtze River Delta region
ContextThe rapid urbanization in China has led to acute land use conflicts between urban expansion and the protection of cropland and ecological land, which have also threatened the sustainable use of land resources and regional sustainable development. However, most current land management policies for solving these conflicts focus on short-term economic benefits, neglecting sustainable land management.ObjectivesThe goal is to propose sustainable land management strategies for balancing the coordinated relationships among urban expansion, cropland protection, and ecological protection in the Yangtze River Delta region (YRDR).MethodsWe used a newly proposed patch-generating land use simulation model to determine the key driving factors and to simulate future land use changes under multiple development scenarios in the YRDR. Additionally, we analysed the evolution process of land use dynamics in the YRDR from 2000 to 2050.ResultsFuture urban expansion was projected to be spatially unevenly distributed under different topographic conditions and among different economic development regions, indicating that more consideration should be given to platform regions and less economically developed areas to meet the demand for future construction activities. Additionally, driving factor analysis suggested that governments should take measures to guide the population to economically underdeveloped areas and that the governments of newly developed areas should focus on extending the local road network first.ConclusionsThe methodological framework for integrating future land use simulations with analyses of driving forces and land use evolution processes can alleviate or eliminate land use conflicts to achieve sustainable land management in rapid urbanization regions.
