Changes In Land Utilization Research Articles

THE IMPACT OF THE SURFACE RUNOFF COEFFICIENT (C) ON LAND UTILIZATION

Transformations in land use from undeveloped to built-up land can increase large surface runoff. This research aims to assess runoff coefficient (C) on changes in land utilization over various periods and times. The method used in this research involves analyzing changes in land use to determine the area of each type of land use over a specific period and then analyze the C value due to land changes. The results reveal that land use in the Way Pubian sub-watershed consists of pond, forest, open land, settlements, plantations, and rice fields area. In certain periods, land use changes, so that different C total value results are obtained in 2012, 2017 and 2022 periods. The C value is significantly affected by the type of land use, because the type of particular land use has different surface runoff coefficient values. The C value obtained from the 2012, 2017 and 2022 periods are close to 0, indicating that all rainwater that falls in the sub-watershed area are infiltrating the soil properly and therefore, land use is classified as good. It can be concluded that the value of the surface runoff coefficient (C) affects the magnitude of changes in land use within a certain period of time.

The Grain for Green Program Promotes Soil Organic Matter Accumulation and Improves Soil Fungal Diversity in the Southwestern Karst Region

Soil microorganisms play pivotal roles in terrestrial ecological processes. However, how soil microbial biomass and community characteristics respond to changes in land utilization in karst regions remains largely unknown. The present study investigated the impacts of land-use change on soil chemical properties, microbial community structure, and biomass in a karst region of southwest China across four land-use types: shrubland (natural vegetation restoration), plantation forest (managed vegetation restoration), orchards, and croplands. Vegetation restoration increased microbial biomass carbon and microbial biomass nitrogen. Shrubland had the highest bacterial and fungal abundance and fungal diversity; in addition, the soil microbial community structure differed significantly among land-use types. The dominant bacterial phyla were Actinobacteria, Proteobacteria, Acidobacteria, and Chloroflexi, whereas Ascomycota was the predominant fungal phylum, with its abundance declining significantly following vegetation restoration. Soil properties, including soil organic matter and available phosphorus, were strongly associated with microbial community composition and diversity in karst areas. The findings of this study are essential for gaining a deeper understanding of how changes in land-use affect soil properties and microbial dynamics, and provide valuable insights for ecological restoration and agricultural management in karst regions.

Diversity and Ecology of Aquatic Insects

This paper presents current information on the variety, ecological characteristics, and preservation of aquatic insects. Although aquatic insects play vital roles in aquatic food webs, nutrient cycling, and serve as bioindicators of water quality, their numbers are currently under risk due to several human-induced stressors, such as habitat destruction, pollution, the introduction of exotic species, and the effects of climate change. This page provides an overview of the primary classifications of aquatic insects, their life cycles, their ability to adapt to aquatic environments, and their ecological roles. This analysis focuses on the conservation obstacles that aquatic insects encounter, such as the consequences of changes in land utilization, chemical pollutants, modifications to water flow patterns, and increasing water temperatures. There are still important areas of information that need to be filled in when it comes to understanding the classification and ecological behavior of aquatic insects in various regions. In addition, we need to better understand the various factors that are negatively affecting their populations, as well as develop efficient methods for conserving them. .

Spatiotemporal dynamics of geomorphology, landuse, and storm surge inundation of FDMN settled in Bhasan Char island using geo-spatial techniques

Bhasan Char has undergone noteworthy transformations in its geographical characteristics since its emergence in 2003. Driven by sediment transported by the Ganges-Brahmaputra-Meghna river system, the island has gradually transitioned from a stretched-out configuration to a more rounded shape primarily due to continuous accretion, while erosion has been minimal since 2012. Currently, the island is being prepared to accommodate over 1 million Forcefully Displaced Myanmar Nationals (FDMN) refugees. This investigation, conducted over the time frame spanning from 2003 to 2023, utilizes multi-temporal satellite imagery to scrutinize the altering geography of the island, encompassing the processes of erosion and accretion, modifications in the coastline, and changes in land utilization and coverage influenced by seasonal variations. By employing the Advanced Land Observing Satellite (ALOS)/Phased Array Type L-Band Synthetic Aperture Radar (PALSAR), the study pioneers an evaluation of storm surge risks that are specific to this island. Additionally, the research utilizes water indices to understand the seasonal geomorphic dynamics of the island and performs a supervised classification to assess land utilization and coverage alterations. The inundation map shows accretion in the north and erosion in the south and southeast. Southwest is the most stable area with the majority population. After the 'Ashrayan -3′ project, significant land use and land cover changes occurred, including urbanization, embankment construction, and agricultural modifications. The average elevation of the island is 2.84 m above sea level, with a risk of inundation from storm surges exceeding 3 m. Rehabilitated populations are particularly threatened if the embankment height of 4.8 m is surpassed. The study's outcomes indicate that other projects worldwide might use the island restoration efforts as a model. This emphasizes how crucial it is to keep an eye on changes in land cover and use for upcoming planning and adaptation initiatives. Moreover, it highlights the necessity of proper assessments of storm surge hazards to guarantee the security and longevity of island communities.

Moving towards plantation: The impact of non-burning agricultural policy on land use and farmers' income in Pulang Pisau Regency, Central Kalimantan

Farmers in Central Kalimantan are accustomed to using fire in a limited and controlled way to clear the land before cultivation. This slash-and-burn was initially legal under Governor's Decree No. 52/2008 until it was completely banned following the major fires in 2015. This study examines the effects of the fire ban on land use and farmers' revenue in the Pulang Pisau regency. Data was collected through interviews and field observations. Respondents were selected from two villages, namely Talio Muara (transmigration village) and Pangkoh Hulu (native village), with 15 respondents for each village. In Talio Muara, there was a remarkable change in land utilization: agricultural land decreased by -44%, plantation land increased by 20%, and unmanaged land increased by 24%. In Pangkoh Hulu, the agricultural land decreased by -20%, while the plantation land increased by 17% and the unmanaged land increased by 3%. Farmers' revenue from land utilization in Talio Muara village decreased by -8% in 2017 compared to 2014, while in Pangkoh Hulu village increased by 13% in the same period. These results indicate that local farmers have adapted better to the burning ban than the transmigrants.

Evaluating the impact of land-use change on Arbuscular Mycorrhizal Fungi (AMF) diversity and function

The ever-increasing change in land utilization has been acknowledged as a primary factor influencing ecological modifications. These alterations have reignited the interest in understanding the enduring consequences on different soil microorganisms, specifically arbuscular mycorrhizal fungi (AMF). This study investigates the effects of land-use changes (LUCs) on AMF diversity, highlighting the impact of forest degradation, intensified farming approaches, and urban growth on the structure of the AMF community and its mediated services. Research has found that deforestation leads to a decrease in AMF diversity, thereby intensifying the susceptibility of particular species to habitat degradation. The transformation of natural habitats into cultivated landscapes due to agricultural spiraling driven by the need for food production also impacts the diversity of AMF. Urbanization, an expeditiously advancing modification of land usage, has been found to have the potential to cause the fragmentation and degradation of habitats, thus impacting ecosystem benefits of AMF, such as nutrient cycling and water filtration. These changes can have far-reaching consequences for plant communities, nutrient cycling, and ecosystem functioning. Future research should prioritize the development of management strategies, investigating AMF-mediated ecosystem services, and comprehending fundamental mechanisms governing AMF responses to land-use change. This knowledge can guide sustainable land management practices emphasizing AMF diversity and function conservation.

Potential ecological risk assessment of land use structure based on MCCA model: A case study in Yangtze River Delta Region, China

Since land resources are essential to human survival, the over-exploitation and unreasonable utilization of land threatens the sustainability of human society. This paper uses the well-developed Yangtze River Delta (YRD) region as a case study, and adopts an improved Mixed-cell Cellular Automata Model (MCCA) to simulate the potential utilization of land resources in 2025 and 2035. Then, the paper attempts to construct a comprehensive assessment system that integrates multiple indicators, and evaluates regional risk changes at a micro patch-cell level and a macro city. The results suggest that (1) The utilization of land resources varies greatly in the YRD region from 2020 to 2035. While Shanghai will continue to make use of available built up land resources, the majority of land resources in Jiangsu Province will shift away from being agricultural in nature. Since forests make up a majority of the land resources in Zhejiang Province, and forests and agricultural land make up a majority of land resources in Anhui Province, the change in land utilization in these two provinces will be more gradual. (2) Changes in land utilization are also likely to cause ecological risks. The risk level in Shanghai is the highest, it is relatively high in Zhejiang but is likely to decrease, relatively low in Jiangsu but likely to increase, and Anhui has the lowest risk level. (3) The K-means clustering method obtained three ecological risk zones of the YRD, and the overall risk level is the highest in the central-eastern zoning ③, followed by the southern zoning ②, and the lowest in the northern zoning ①. Furthermore, the agglomeration pattern of the three zones transforms from L-L to H-H. (4) This paper puts forward corresponding suggestions and countermeasures for four aspects, including the strengthening of agricultural land protection, the regulation of built-up land use expansion, the coordination of an all-rounded approach of urban development, and the fostering of regional sustainable development, in hopes of optimizing land usage and alleviating ecological risk levels. Scientific estimations of potential ecological risks are critical to avoiding future ecological crises thus contributing to more sustainability.

Land utilization types impacted the species diversity and population distribution of nodulating and non-nodulating rhizobia in the Philippines

The influence of three land utilization types (LUT) on the diversity and population of soybean-nodulating rhizobia indicated how human activities affect the ecology of these microorganisms. This report revealed that based on LUT (LUT1-rice-based; LUT2-soybean-based; LUT3-legume-rice), different species of rhizobia can be more abundant than the other species. Targeting the 16S rRNA gene and the 16S-23S rRNA gene ITS region through Polymerase Chain Reaction - Restriction Fragment Length Polymorphisms (PCR-RFLP), it was found out that a majority of the nodulating rhizobia was classified under the genus Bradyrhizobium and the non-nodulating rhizobia was classified under the genus of Sinorhizobium. The species diversity of nodulating rhizobia on the LUT2 showed the lowest at 0.00 whereas the LUT1 showed the highest diversity at 0.87. Similarly, the lowest species diversity of the non-nodulating rhizobia was found on the LUT2 at 0.00 but the highest was obtained from the LUT3 at 0.69. These results suggest that the nodulating rhizobia in this study may have preference with rice-based cropping pattern than with the two cropping systems. On the other hand, the diversity of rhizobia observed on LUT2 indicated that soybean monocropping may have resulted to a lesser diversity of both nodulating and non-nodulating rhizobia.Thus, it can be stated that the change in land utilization even in an agriculture land-use, species diversification and population dominance of certain rhizobia may occur.

Dynamic monitoring and prediction of ecosystem service value (ESV) under land utilization change is of great significance to maintaining regional ecological security. In order to enrich the study of ESV changes in plateau region by using the improved equivalent factor method of unit area value, the western Sichuan Plateau was taken as the research object. In this paper, given the land use data of the western Sichuan Plateau in 2000, 2010 and 2020, efforts have been made to construct the suitability image collection of the study area and to amend the CA-Markov model as to predict the land use pattern in 2030. In addition, the improved ESV evaluation model was constructed to study the spatial and temporal dynamic variation features of ESV. The results showed that: Woodland and grassland are the main types of land utilization in the study area. There are frequent interchanges between various land utilization types. The overall reduction of ESV, decrease of 3.4917 × 109 yuan/a, mainly due to the conversion of woodland to other land types. The high-value areas of ESV in the study area are closely tied to rivers. Two areas with high ESV value were formed in the study area. The findings of the study enriched the research system of land use and ecosystem service value in the plateau region, provided basic data for the construction of regional ecological security pattern, and enhanced regional sustainable development.

Multi‐scenario simulation of land use change based on MCR‐SD‐FLUS model: A case study of Nanchang, China

AbstractModeling land use/cover change (LUCC) is a helpful approach to simulate land use changes, analyze land use driving mechanisms, and support territorial spatial planning. However, there is no single model that comprehensively represents spatiotemporal changes, impact mechanisms, and ecological conservation of land use. This article focuses on Nanchang City and how the minimum cumulative resistance (MCR) model, the system dynamics (SD) model, and the future land use simulation (FLUS) model can be combined and applied to simulate the trends of land utilization change in different future scenarios. This allows us to explore the environmental protection policies and constraints, as well as to assess the socioeconomic regulation mechanisms and dynamic spatial patterns of land use. The results proved that the integrated model is competent in monitoring and projecting the dynamics of LUCC. The areas suitable for ecological protection are mainly located in the southeast, northeast and Meiling Scenic Area of Nanchang. By 2030, the scale of cultivated land will decrease, while the scale of forestland, grassland, water area, and total construction land will increase. Spatially, some cultivated land will be occupied due to the expansion of urban land, while the rural settlement land will be converted into other construction land. The interconversion of ecological lands also encroaches on part of the cultivated land. This scenario simulation based on the coupled MCR‐SD‐FLUS model provides decision‐making options for land resource planning and ecological environment assessment not only in the study region but also in other similar cities.

Determinants of net primary productivity: Low-carbon development from the perspective of carbon sequestration

Net primary productivity, which reflects vegetation's carbon sequestration capacity, should not be ignored in the process of low-carbon development. To explore the paths of achieving low-carbon development goals from the perspective of carbon sequestration, this study takes net primary productivity as the study object and uses the logarithmic mean Divisia index decomposition model to analyze the influences of urbanization and land utilization change on net primary productivity in China. The results show that urbanization is the driving factor of the net primary productivity increase, and land utilization change is the main determinant of its decrease. This study argues that making reasonable land utilization planning is essential to reduce the net primary productivity loss caused by land utilization changes in the process of urbanization.

In short, the change in land utilization has a direct impact on hydrological behavior.

Quantitative assessment of water level regime alterations during 1959–2016 caused by Three Gorges Reservoir in the Dongting Lake, China

Abstract Water level is considered as the key factor affecting the structure and function of lake ecosystems. The Mann-Kendall technique and range of variability approach (RVA) were used to quantitatively evaluate the hydrologic alteration due to Three Gorges Reservoir (TGR) in Dongting Lake. Results indicate the following. (1) The average annual water levels at Chenglingji station showed increasing trends (p < 0.05), while that at Nanzui station showed a decreasing trend (p < 0.05). The turning year occurred in 2003, which reflects the significant effects of the TGR on the water level regime. (2) The highly altered parameters were 1-, 3-, and 7-day minimum water levels both at Chenglingji and Yangliutan, and in October both at Nanzui and Yangliutan, with the degree of hydrologic alteration being larger than 80%. However, 1-, 3-, 7-, and 30-day maximum water levels at three stations had relatively small alteration, with the degree of hydrologic alteration being smaller than 41%. (3) The hydrologic alteration degrees at Chenglingji, Nanzui and Yangliutan station were all moderate, with changes of 50, 46 and 49%, respectively. (4) Water level regimes at Dongting Lake were mainly jointly affected by reservoir operation, land utilization change and river channelization. These changes in water level regimes have a negative impact on aquatic and terrestrial ecosystems. This study provides a scientific reference for the protection of lake ecosystems under hydrologic alteration.

Land Use Change Along Lebih Coastal Line, Entailing Its Designation as A Zone for Tourist Development

The coastal area is a physically productive area, but is easily degraded which may be due to the lack of planning or even natural factors. The coastal area in Gianyar has experienced a drastic physical development, especially after it is declared as Lebih Tourist Zone or Lebih Tourist Zone (LTZ) and the construction of the arterial road between Tohpati and Kusamba. The study documented in this paper discusses: (i) the form in which the coastal area in Gianyar are utilized post the recognition as the LTZ; (ii) the factors that influence the changes in land utilization in this region; and (iii) how does this condition affect the sustainability of the LTZ. Fundamentally, this study applies the conception of sustainable development and the descriptive qualitative research method. The data were collected through field surveys and in-depth interviews with the land owners, land users, and the authority. The research results showed that the LTZ has experienced a significant change, both physically and non-physically. The factors that influence this change in function is the physical condition of the land, economy, institutional factors, and accessibility. This change has implications for the environment, economy and social culture. This study concludes to develop the sustainability of the LTZ some fundamental actions must be made, namely: evaluate the usage of land, establish clear and restricting zoning law to anticipate any land use violation; consistency in the layout plan; the active participation in the control of land use by the government, the people and private sectors; providing incentives and disincentives in utilizing the space.

A Study on the Spatio - Temporal Trend in the Pattern of Land Utilisation with Respect to Temperature and Rainfall in the Southern Districts of Tamil Nadu

Land and water are the two main physical parameters of the earth. The earth contains 78% of water and 21% of land and remaining 1% with gases. Even though, water is in large volume, land is more utilised. So, the proper utilization of land is necessary for sustainable development and growth. The land utilisation is defined as the way by which each piece or part of the earth is used by the human for development. The production in agriculture increases with proper utilization of the land. The wider fluctuations in agricultural production are experienced due to improper utilisation of land. Therefore, for high agricultural production, a systematic and scientific plan of land utilisation is essential. Climate is one of the main parameter determining the regional and global pattern of land utilization. The utilisation of land depends on the climatic variables such as temperature and rainfall. The study of the trend and temporal dynamics in the utilization of land with respect to climatic variables is an emerging problem and it is the need of the hour to determine the changes in the earth. In this study, attention is focused to analyse the changes in the utilization of land with respect to climatic variables for a particular time period. The climatic variables such as temperature and rainfall are analysed for 20 years (viz. 1990 - 2010) using the trend analysis, whereas land utilisation is analysed for the recent decade (viz. 2000 - 2010). The analysis is done at block level for the 40 blocks of the southern three districts of Tamil Nadu, the area lying in varying agro-climatic conditions. The trend analysis of climatic variables shows variation for each block viz. nearly 14 blocks shows positive trend and 26 blocks shows negative trend. The utilisation of the land in the study area is classified based on nine-fold classification, and the temporal changes are identified. The maps are generated in Arc GIS for understanding the spatial distribution. The data collected from the statistical department pertaining to the land utilisation is compared with the changes in climatic variables. The results of the present study emphasize the spatial and temporal change in land utilization using trend analysis, and the usefulness of relating the climatic parameters with land use / land cover change.

Effects of the land use change on ecosystem service value

The impacts of land utilization change on the ecosystem service values in Daqing during 1995 to 2015 were analyzed based on unit area ecosystem service value of Chinese territorial ecosystem from Mr. Xie Gaodi and ecosystem service value calculation formula from Costanza. Results showed that the ecosystem service value of Daqing decreased from US $4343.1559m in 1995 to US $3824.327m in 2015, with the ecological value of US $518.8289 m decreased during the past 20 years. Wetland and water body were the two main land utilization types with the greatest contributions to the ecosystem service value. Ecosystem services value of per capita decreased 23.52%. The sensitivity coefficient of eco-service values of all types of land utilization to their value coefficients were all less than 1 in Daqing area. The sensitivity coefficients followed that wetland > water body > woodland > unutilized land > pasture land> cultivated land in 2015, which indicating that the changes of the land utilization are lack of flexibility to the changes of the ecosystem service value.

DPSIR MODEL AS A TOOL TO ASSES LAND CONVERSION TARIFF POLICY IN YOGYAKARTA

Land use change from agricultural land to non-agricultural purposes in Yogyakarta Special Province (DIY) is the main factor leading to the decrease of agricultural land. The increasing population growth has led to a higher demand for land, which is contributing to the rapid land use changes. Land scarcity has led to a change in land utilization within the city and in the surrounding area. The DPSIR Model is used as the basis for the impact assessment analysis on the tariff policy implementation regarding to the controlling of the land use change. Driving force in this model is migration and the pressure is land use change. The state is divided into three categories, state of economic dimension, environmental dimension, and social dimension. These have caused impacts on land degradation, threats to food security, and pollution. As the response to this, the government introduced the policy PERDA No. 53 Year 2007 about authorizing land use in DIY. This paper is intended to explain how the DPSIR model is used to assess the policy implementation.Keywords: DPSIR, Assessment, Land Use Change, Land Use Policy.
