미국에서의 콘도미니엄 관리

Like apartment buildings in Korea, condominiums in the United States are not a physical style or type of building, but rather a mode of ownership. In addition to the physical elements of private and common areas, condominiums in the U.S. also have an owner's association as a human element. However, unlike Korea, the human factor is much stronger than the physical factor. This is because the U.S. condominium law focuses on collective management of property. On the other hand, the Korean Collective Buildings Act has emphasized the right of separate ownership of the exclusive use part from the time of its enactment, as it originated from the modification of the sharing theory of the civil law to adjust the sharing relationship between the exercise of ownership of each exclusive use part and the common part or land, and to promote the survival of each unit owner with respect to the sharing relationship. However, collective buildings in Korea are becoming larger and larger, and large apartment complexes with many facilities are becoming more popular, and the proportion of common areas to the total area is increasing. Therefore, even in the Collective Building Act, it is necessary to strengthen the human factor through the community of residents to manage the common areas and control the interests of users of the common areas, such as noise between floors.

Research on Hyperspectral Surface Reflectance Dataset of Typical Ore Concentration Area in Hami Remote Sensing Test Field

Abstract. Surface reflectance data is the basic data source for the hyperspectral parametric remote sensing products and remote sensing quantitative application, which is widely used in various application fields such as natural resources and ecological environment monitoring. At present, multispectral data takes the leading role among the common land surface reflectance datasets and the reflectance data mainly involves the types of ground objects such as farmland, forest land, water body, soil, etc., while the datasets relatively less targets the types of rock and mineral surface objects, yet especially the reflectance datasets with the combination of time series and multi-scale satellite-earth are even more scarce. In order to better promote the application of hyperspectral surface reflectance and explore the advantages of joint application of satellite-earth multi-scale reflectance data, on the basis of field-measured rock and mineral target spectral, a comprehensive surface reflectance dataset was generated by using domestically produced hyperspectral satellite data as the data source in this study, mainly focusing on the typical ore concentration area in the Hami Remote Sensing test field in Xinjiang. The dataset includes multi-period hyperspectral satellite surface reflectance images, field measured rock and mineral spectral data, and multi-period sub-pixel spectral data collected based on ground spectral measured points, which can provide significant support for the research and development and accuracy verification as well as performance evaluation of algorithms such as surface reflectance inversion, mineral identification and ground object classification.

Development and preliminary validation of a land surface image assimilation system based on the Common Land Model

Abstract. Data assimilation is an essential approach to improve the predictions of land surface models. Due to the characteristics of single-column models, assimilation of land surface information has mostly focused on improving the assimilation of single-point variables. However, land surface variables affect short-term climate more through large-scale anomalous forcing, so it is indispensable to pay attention to the accuracy of the anomalous spatial structure of land surface variables. In this study, a land surface image assimilation system capable of optimizing the spatial structure of the background field is constructed by introducing the curvelet analysis method and taking the similarity of image structure as a weak constraint. The fifth-generation ECMWF Reanalysis – Land (ERA5-Land) soil moisture reanalysis data are used as ideal observation for the preliminary effectiveness validation of the image assimilation system. The results show that the new image assimilation system is able to absorb the spatial-structure information of the observed data well and has a remarkable ability to adjust the spatial structure of soil moisture in the land model. The spatial correlation coefficient between the model surface soil moisture and observation increased from 0.39 to about 0.67 after assimilation. By assimilating the surface soil moisture data and combining these with the model physical processes, the image assimilation system can also gradually improve the spatial structure of soil moisture content at a depth of 7–28 cm, with the spatial correlation coefficient between the model soil moisture and observation increased from 0.35 to about 0.57. The forecast results show that the positive assimilation effect could be maintained for more than 30 d. The results of this study adequately demonstrate the application potential of image assimilation system in short-term climate prediction.

The Robustness of Common-Pool Resource Governance in the Gulf of Mottama Ramsar Wetland, Myanmar under Pre- and Post-Political Crisis Conditions

This study examines the role of communities, local institutions, conservation organizations and government agencies in the governance of large-scale common-pool resources (CPR) at the Gulf of Mottama Ramsar wetland, Myanmar before and one year after the 2021 coup d’état. The research employed a mixed method approach in two villages in the GOM on common alluvial land, waterbirds, and fisheries CPRs. The robustness of CPR governance is evaluated with Ostrom’s eight design principles. We found that pre-coup the formation of local user associations, livelihood incentive strategies, and co-management approaches were increasingly effective to conserve fisheries and waterbirds CPRs, while land conflicts over new common alluvial land persisted. One year following the coup, offshore fisheries especially faced challenges from illegal practices by outsiders, due to significantly weakened co-management practices and accountability of local authorities and large-scale commercial fishers to the fishing communities.

STRATEGY FOR IMPROVING THE COMMUNITY ECONOMY THROUGH ENVIRONMENTALLY BASED TOURISM AND SOCIAL MEDIA IN NAGARI SUNGAI PINANG, WEST SUMATRA PROVINCE

This research aims to identify strategies to improve the community’s economy through environmentally based tourism and social media in Nagari Sungai Pinang, Pesisir Selatan Regency, West Sumatra. This study used qualitative methods with observation, in-depth interviews, utilization of documentation, and FGD. As an analytical tool, this research used Anthony Giddens’ structural theory of observation practice which is not only determined by the agent but also by structure. According to the research findings, the strategy for improving the community’s economy through environmentally based tourism and social media can be seen in the utilization of the community’s diverse tourism business potential, which includes tourism beaches, tourism mangrove forests, tourism nautical (sea), and tour island. Homestay, Manjuto Beach, and attractive islands such as Pamuntusan Island, Pagang, Marrak, Karanggo, and Erong Bay have all contributed to the growth of business tourism. Its development is aided by local institutions and local expertise from an environmental standpoint. There are other opportunities for enterprises that may be established without damaging natural beauty, including tourist firms that involve underprivileged people. The strategy for enhancing the economy of the public is to include all components from the outset, given that the location is common land in line with the customs that apply in the community of Minangkabau West Sumatera. Apart from that, social media is also used as a promotional tool by involving the younger generation.

Optimizing Parameters in the Common Land Model by Using Gravity Recovery and Climate Experiment Satellite Observations

Terrestrial water storage (TWS) is pivotal in understanding environmental dynamics, climate change, and human impacts. Despite the utility of land surface models, uncertainties persist in their parameterization schemes. This study employs GRACE (Gravity Recovery and Climate Experiment) satellite data to optimize the runoff parameterization scheme within the Common Land Model by a data assimilation and parameter optimization method. The optimization algorithm sets an adjustment factor that varies with time and space for runoff simulation and updates it along with the running of the land surface model. The evaluation reveals that there are improved correlation coefficients and reduced root mean square errors compared to GRACE observations. Independent assessments by using in situ river discharge observations demonstrate enhanced model performance, particularly in mountainous regions such as western North America. This study underscores the efficacy of integrating GRACE data to improve land surface model parameterization, offering more accurate predictions of TWS changes.

Enabling Spatial Data Interoperability through the Use of a Semantic Meta-Model—The Peatland Example from the JRC SEPLA Project

Numerous geographic data on peatland exist but definitions vary, and the correspondent classes are often neither harmonized nor interoperable. This hinders the efforts to employ the available national datasets on peatlands and wetlands for policy monitoring and reporting. The existing meta-languages, such as ISO-Land Cover Meta Language (LCML) and EAGLE, offer the possibility to “deconstruct” the relevant nomenclatures in an object-oriented manner, allowing the comparability and interoperable use of related information. The complex nature of peatlands calls for a dedicated and structured vocabulary of keywords and terms, comprising the biotic substrate and the soil. In the SEPLA project, a semantic meta-model has been developed, combining the hierarchical ontology of the LCML with the matrix structure of the EAGLE model. The necessary elements were provided to describe peatland bio-physical characteristics, while representing the definitions in a concise and user-friendly manner (semantic passports). The proposed semantic meta-model is innovative as it enables the documentation of the spatial distribution of peatland characteristics, considering also their temporal dimension, their intrinsic relation with land use, and the soil. It has been successfully implemented for the translation of the national peatland nomenclature into common land categories relevant for reporting under LULUCF regulation, as part of the EU Climate Law.

ET cool home: innovative educational activities on evapotranspiration and urban heat

Abstract. Teaching evapotranspiration (ET) in university courses often focuses on either oversimplified process descriptions or complex empirical calculations, both of which lack grounding in students' real-world experiences and prior knowledge. This calls for a more applied approach to teaching about ET that connects concepts to experience for improved educational outcomes. One such opportunity exists at the intersections between ET and heat in cities, where a growing majority of the world's population lives, including many of our students. In this work we describe an ET educational activity that integrates theory with practical design, taking advantage of the close link between ET processes and urban heat patterns. In a benchtop experiment, students measure ET variations across common land surfaces (e.g., asphalt, grass, and mulch) through water and energy balance approaches. The experiment is paired with an “urban heat tour” in the campus environment, facilitated by portable infrared cameras, offering firsthand observation of urban heat patterns. These two activities, together, provide context in which students can understand the difference in ET across various land covers, describe the relationship between ET and land surface temperatures, and explain the impacts of urban design on heat dynamics. The activities are adaptable to serve a diversity of student backgrounds and to different educational contexts, including public demonstrations and pre-university classrooms.

The farce of the commons? Corporate rights, political wrongs and common-pool resources in English towns, 1835–1870

ABSTRACT The 1832 Reform Act and the 1835 Municipal Corporations Act reconfigured political representation in English towns from a ‘franchise’ system (based on rights of corporate freedom) to a property-based ratepaying electorate. This shift also undermined the rights of freemen to urban common lands and resources, which were linked to pre-existing forms of representation. This issue links directly to debates in economic history about use-rights and the preservation of common-pool resources (CPRs). Supporters of Nobel laureate Elinor Ostrom argue that such common resources could be preserved because this was the most rational economic choice facing their users. Critics have asserted that the fate of such economic resources was dictated by the historically contingent social, economic and political forces within them, not abstract economic rationality. This article assesses these arguments through a micro-study of the commons in the Yorkshire borough of Beverley between 1835 and 1870. New legislation ensured that these lands were managed in line with Ostrom’s principles of transparency and accountability. Despite this, they became entangled in wholesale, organised political corruption, exposed by a detailed Parliamentary enquiry in 1868. The article investigates this contradiction to explore how far ‘institutions’ could remain autonomous within a highly contested political ‘space’.

An optimal ensemble of the CoLM for simulating the carbon and water fluxes over typical forests in China

Stomatal conductance (gs) and compensatory water uptake (CWU) are crucial processes in land surface models, as they directly influence the exchange of carbon and water fluxes between terrestrial ecosystems and the atmosphere. In this study, we integrated a new stomatal scheme derived from optimal stomatal theory (Medlyn's gs model), and an empirical CWU scheme into the Common Land Model (CoLM). Assessing the impacts on modeling gross primary productivity (GPP) and latent flux (LE) through observations obtained from eddy covariance (EC) measurements at three forest sites in China. Our results show that replacing the Ball-Berry's gs model (termed BB) with Medlyn's gs model (termed MED) did not bring about significant changes (had neutral impacts) in the performance of CoLM simulations at three forest sites. Considering the climate factors of annual mean precipitation to optimize key fitting parameters in gs exhibited improvement in model simulations. The average coefficient of determination (R2) achieved to 0.65 for GPP and LE at three sites, and the normalized root mean squared error (NRMSE) decreased from 0.83 to 0.77 at those sites. Besides, incorporating CWU into the model improved its performance. The R2 increased to 0.84 and RMSE decreased to 4.84 μmol m−2 s−1 for GPP, and the R2 increased to 0.62 and RMSE decreased to 55.64 W m−2 for LE. Therefore, modifying the model process of both contributed more to enhancing the model simulations than relying solely on one of these functions. Our study highlights that the response of plant functional types (PFTs) to water stress can be effectively represented in gs models when coupled with biochemical capacity to quantify carbon and water fluxes in forest ecosystems or other ecosystems.

An Unstructured Mesh Generation Tool for Efficient High‐Resolution Representation of Spatial Heterogeneity in Land Surface Models

AbstractThis study develops an unstructured mesh generation tool for land surface modeling using a multi‐scale hexagon discrete mesh. The tool can automatically determine the required mesh resolution for different regions based on multi‐objective criteria such as elevation, slope, land cover, and land use. The refined unstructured meshes demonstrate significant enhancement in the representation of spatial heterogeneity. The tool is coupled with the Common Land Model (CoLM) to enable land surface simulations using unstructured meshes. Evaluations focused on runoff, river discharge, and inundation indicate improved model performance compared to traditional structured mesh‐based CoLM simulations under the same computational cost constraints. This tool provides new capabilities for more efficiently capturing localized land surface processes and extreme events.

Wégoubri, an innovative agroforestry solution for rain-fed agriculture in the Sahel

The Sahelian rural environment has been deteriorating due to local agricultural practices, threatening rural populations. Terre Verte, an NGO, was established in 1989 to address this environmental degradation, by supporting the Guiè pilot farm in Burkina Faso, wherein they promoted bocage. Bocage involves creating a landscape of meadows and fields surrounded by living hedges, to form a continuous network - a linear forest - where trees, crops and livestock are integrated. These hedges store rainwater during the monsoon season, which reduces runoff and soil erosion, improving soil fertility. The hedges also prevent the problems associated with extensive agriculture including overgrazing, slash-and-burn farming and excessive firewood cutting. Bocage areas are established at the request of landowners and are managed collectively by a land-owning group, combining individual plots and common land. The implementation of bocage at the Guiè pilot farm involved experimentation with new techniques, training in these new techniques, and providing advice and support to farmers. Maintenance is managed by the land-owning group who ensure compliance with the control of livestock, of fire and of wood cutting. Early planting of crops is made possible by Zaï cultivation, a traditional cereal-growing technique that concentrates water and nutrients around cultivated plants. This regenerates the soil and ensures crops survive changes in the weather. Trees in the bocage play a crucial role in encouraging biodiversity and their fertilising functions enrich soil, desalinate it, and produce good compost. The hedges provide firewood and fodder, and the trees provide fruit for consumption, while their leaves and roots are used for local medical practices and cultural traditions. The bocage also creates a microclimate favourable to flora and fauna, conserving species on the verge of extinction. By integrating principles of agroforestry, the bocage approach has successfully increased biodiversity and agricultural productivity, making it a genuine solution for restoring degraded land in the Sahel and improving the livelihoods of rural populations.

Analysis of Management Practices and Breeders' Perceptions of Climate Change's Impact to Enhance the Resilience of Sheep Production Systems: A Case Study in the Tunisian Semi-Arid Zone.

Global climate change inflicts unambiguous risks on agricultural systems and food security. Small ruminants are known for their ability to adapt to changing environmental conditions. This paper aims to characterize sheep production systems in a vulnerable agricultural zone and the breeders' perceptions of climate change to apprehend challenges that they are confronting, and formulate resilience actions. The data analysis is based on 94 semi-structured surveys of sheep farmers carried out in the Tunisian semi-arid region. The PCA analysis results revealed three main sheep production systems. The agro-pastoral rain-fed system (AGPRF) is dominant (55%), with large farms and common pastures integrating cereals and fodder. The agro-pastoral irrigated system (AGPI: 20%) is characterized by small-area and forage irrigation (1.8 ha) and a smaller number of ewes but a greater use of animal feed supplementation. The agro-sylvo-pastoral system (AGSP: 25%) is a system where grazing is based on common lands and using tree sub-products, while the agricultural area is exclusively used to cultivate cereal crops. Sheep breeders' climate perceptions are summarized as unpredictable climate events, a decrease in precipitation, and an increase in temperature. Resilience actions principally consist of reducing flocks' numbers, using alternative local feed, fodder, and water resources, and building more shelters and planting more trees in the grazing areas. Nevertheless, cost-effectiveness should be considered in such vulnerable zones to insure the sheep production systems' sustainability.

The Role of Siyāsah Shar'iyyah in Analyzing and Addressing Land Disputes

Disputes are often reported from complexities related to land ownership, particularly when multiple parties lay claim to a specific plot acquired through gifting or inheritance. Public objections predominantly center around preventing inaccuracies in the transfer of ownership rights during the recording of land blocks at National Land Office (BPN) concerning blocking of ownership rights. Therefore, this study aims to examine the prevalent issues encountered during the recording of land title certificate, with a specific focus on the common land disputes that lead to legal proceedings. An analytical framework of siyāsah shar'iyyah is adopted with empirical juridical methodology using a socio-juridical perspective. The data-gathering method comprises three distinct stages, namely reduction, presentation, and conclusion. The results show that the submission of a plot of land for registration cannot be executed by any arbitrary party. A clear understanding of applicant's status and the rationale behind the request is necessary to restrict the use of land effectively. In this context, the registration of land blocks has diverse effects in terms of economic, socio-cultural, and legal assurance. The challenges encountered in the act of obstructing are predominantly rooted in the administrative procedure. Therefore, the proposed remedy includes the use of technology based on electronic systems to effectively disseminate information to the public. In this jurisdiction, land ownership is primarily governed by Sharia law, which views documenting property rights as a method of promoting good governance. Meanwhile, zoning arrangements serve as an alternative for documenting land blocking, mitigating potential ownership issues in the future.

A Review of the Sediment Production and Transport Processes of Forest Road Erosion

Forest roads are a common land use feature with a significant impact on sediment yield and the water sediment transport processes within a watershed, seriously disrupting the safety and stability of the watershed. Previous studies have focused on the sediment production processes within the road prism. However, there has been limited attention given to the transport processes of road-eroded sediment at various scales, which is crucial for understanding the off-site effects of road erosion. This paper reviews research conducted on forest road erosion over the past two decades. It summarizes the mechanisms of sediment production from road erosion and provides a detailed analysis of the transport mechanisms of eroded sediments from roads to streams at the watershed scale. The paper also examines the ecological and hydrological effects, research methods, and control measures related to sediment transport caused by forest road erosion. It identifies current research limitations and outlines future research directions. The findings of this review highlight several key points: (1) Most research on forest road erosion tends to be specific and unilateral, often neglecting the broader interaction between roads and the watershed in terms of water–sediment dynamics. (2) Various research methods are employed in the study of forest road erosion, including field monitoring, artificial simulation experiments, and road erosion prediction models. Each method has its advantages and disadvantages, but the integration of emerging technologies like laser scanning and fingerprint recognition remains underutilized, hindering the simultaneous achievement of convenience and accuracy. (3) The transport processes of forest road-eroded sediment, particularly on road–stream slopes, are influenced by numerous factors, including terrain, soil, and vegetation. These processes exhibit significant spatial and temporal variability, and the precise quantification of sediment transport efficiency to the stream remains challenging due to a lack of long-term and stable investigation and monitoring methods. The establishment and operation of runoff plots and sedimentation basins may help offer a solution to this challenge. (4) Both biological and engineering measures have proven effective in reducing and limiting sediment erosion and transport. However, the costs and economic benefits associated with these regulation measures require further investigation. This review provides a comprehensive summary of relevant research on sediment erosion and transport processes on unpaved forest roads, enhancing our understanding of sediment yield in watersheds and offering valuable insights for reducing sediment production and transport to streams.

Management dampens seasonal variability in soil microclimates and alters its chemical and physical properties in a semi-arid region

Abstract The urbanization process substantially alters every aspect of the soil environment. In this study, we compared soil microclimate, chemistry, and physical characteristics of unmanaged natural soils with managed soils of three common urban land uses (stormwater natural treatment systems, ornamentally landscaped areas, and lawns) across three University of California campuses. Over the course of 1-year, average monthly soil temperatures among land uses showed fewer than expected differences. Average monthly soil moisture reflected wet and dry seasonal changes, but this pattern was muted in managed land uses compared to natural soils due to irrigation. From April through December, lawns and landscaped areas were significantly wetter than natural soils (e.g. 1.5–3 times higher in August and September). Soil organic matter, total carbon, and total nitrogen were significantly higher in lawns compared to other land uses, while their bulk density was significantly lower. Principle component analysis confirmed that natural and lawn soil properties were distinct from each other. These differences in the managed soils, particularly lawns, are attributable to typical urban land management practices such as fertilization, irrigation, and the installation of organic-rich sod. As urbanization continues to change the native landscape of semi-arid regions, these changes to soil microclimate, chemistry, and physical characteristics are important to consider for urban best practices and sustainable development.

Erode Ground Gecko Cyrtodactylus speciosus (Beddome, 1870) (Squamata: Gekkonidae) from peri-urban common-lands of Coimbatore, India, with comments on habitat associations

We report the Erode Ground Gecko Cyrtodactylus speciosus (Beddome, 1870), a rare, hill forest-dwelling species, from two sites in the northern periphery of Coimbatore city. These two sites, viz., Nallusamy checkdam (Site–1) and Sarkar Sama Kulam (Site–2) are lakes with remnant vegetation belts, surrounded by pastures, farmlands, and villages. From 100 hours of observations during a six-month period (April–September 2023) in these two sites, we report 14 sightings of C. speciosus including gravid females, juveniles, and subadults indicating a persistent breeding population. The encounter rate estimates ranged from 5 h (in Nallusamy checkdam; n = 10/50 h) to 12½ h (in Sarkar Sama Kulam; n = 4/50 h), averaging at about 7 h (pooled; n = 14/100 h) to get one sighting of C. speciosus. Our sightings of C. speciosus in peri-urban common lands abutting a city, calls for intensified biodiversity surveys and enhanced protections of such remnant vegetation belts, often presumed to have low or marginalised conservation values.

Soil Water in Different Management Systems of Coffee-Pine Agroforestry and Its Relation to Coffee Bean Yields

Coffee-pine agroforestry is a common land use system in Indonesia, that provides several benefits, including increased soil fertility, biodiversity, and economic returns. However, the management of coffee-pine agroforestry systems can significantly impact on soil water dynamics, affecting coffee bean yields. This study investigated the effects of different management systems on soil water dynamics and coffee bean yields in a coffee-pine agroforestry system in UB Forest, Malang East Java, Indonesia. Five different management systems were evaluated: (i) no management, (ii) pruned coffee with no fertilizer, (iii) pruned coffee with added organic fertilizer, (iv) pruned coffee with added organic-inorganic mix fertilizer, with a planting distance of pine trees of 3 x 2 m, and (v) pruned coffee with added organic-inorganic mix fertilizer under pine trees with a planting distance of 6 x 2 m. The soil water dynamics were measured at depths of 0-0.2 m with a soil moisture sensor and connected with a data logger measured within a year, started in April 2022. Coffee bean yield was measured with 100 coffee plants, then converted to production on ton ha−1. The results showed that the different management systems significantly impacted soil water dynamics and coffee bean yields. The combination of pruning and fertilization is a promising management strategy for increasing coffee bean yields in coffee-pine agroforestry systems. The consequent better growth of coffee plants impacts increasing soil water extraction. This study provides valuable insights for farmers and forest managers who are interested in improving the productivity of coffee-pine agroforestry systems and conserving soil water or sometimes needing water addition through irrigation.
