Identification of Potential Land Use Conflicts in Shandong Province: A New Framework

Land use conflicts (LUCs) have become a significant global issue. Accurately identifying potential LUCs is crucial for mediating these conflicts, optimizing land use structure, and enhancing land use function. The necessary conditions of LUCs are land use multi-suitability (LUMS), land resource scarcity (LRS), and diversity of demands (DD). However, few studies have approached LUC identification from these three dimensions simultaneously. In addition, when assessing the diversity of demand, only human needs are considered and wildlife needs are ignored. In order to address this gap in the research, this paper constructs a novel framework for LUC identification and proposes an induction-oriented governance path. LUMS was evaluated from three aspects: construction suitability, cultivation suitability, and ecological suitability. LRS is measured from three dimensions: construction land, cultivated land, and ecological land scarcity. The DD is expanded into human and wildlife demand diversity. By analyzing the combination of LUMS, LRS, and DD, LUCs are classified using the potential LUC identification Rubik’s cube model, and corresponding governance paths are suggested. In Shandong Province, potential LUCs are relatively high, with strong, medium, and weak conflicts accounting for 27.39%, 57.10%, and 13.06%, respectively. Potential strong conflicts are mainly distributed in the metropolitan suburbs and in the western plain of Shandong Province. Cultivated land is the main potential land use conflict space. The new framework of LUC identification proposed in this paper can effectively identify potential LUCs. Our research provides scientific reference for sustainable land use.

The adaptability of Garut sheep grazing on oil palm and rubber plantations in tropical conditions of Indonesia.

The productivity of sheep in humid tropical plantation areas relies on their ability to adapt. Oil palm plantations serve as potential grazing lands for livestock. This study aimed to identify Garut sheep adaptations in oil palm and rubber plantations of the Garut district, West Java, Indonesia. The total number of sheep used was 103 as the object of this study. Each individual of sheep was used for several different observations, including: Physiological assessment using 24 sheep of various ages, molecular analysis of heat stress using 31 sheep, worm egg count using 59 sheep, and for morphological assessment using 98 sheep. A general linear model was employed to analyze rectal temperature (RT), heart rate (HR), respiratory rate, number of eggs in each gram of sample feces, body weight (BW), body condition score, and morphometric measurements according to age and sex. Forage was compared between oil palm and rubber plantations during the vegetation analysis. RT, HR, and panting frequency were significantly (p < 0.05) affected by the age and sex of the sheep. The mutation was found in the coding region of the HSP70 gene, which is approximately 232 bp long. Fecal eggs were found in 99% of the fecal samples, consisting of 100% Strongyle eggs and 1.75% Moniezia eggs. BW, body condition score, shoulder height, body length, pelvic height, chest circumference, and number of eggs were significantly affected (p < 0.05) by the age and sex of the sheep. The average fresh matter of vegetation under the plantation was 248.69 ± 120.94 g/m2 and 718.15 ± 249.93 g/m2 for oil palm and rubber plantations, respectively. Garut sheep were adapted to oil palm and rubber plantations in the humid tropical region. Plantations are potential sources of sheep grazing and roughage. Further research is needed regarding the consumption of forages in oil palm and rubber plantations.

While the potential land suitability is quite suitable (S2tc.wa) for all land units in Moncongloe District, Maros Regency. The inhibiting factors are average temperature (tc) and water availability (rainfall).

Development and application of a simplified biophysical model to study deltaic and coastal ecosystems

Many coastal regions around the globe experience land loss due to high relative sea level rise rates, declining sediment supply, and a host of other anthropogenic factors. To evaluate possible restoration strategies, we developed a computationally efficient Simplified Biophysical Model (SBM). The SBM includes hydrodynamic, morphodynamic, and marsh inundation components. The hydrodynamic and mineral sediment processes of the SBM are based on open source Delft3D models. The marsh inundation MATLAB module is a simplified vegetation response to salinity and inundation used to estimate annual organic accretion rates. Organic accretion is added annually to the morphodynamic calculations of mineral sediment. The typical run time for the SBM for an area of 4500 km2 is ∼0.8, 2.5, and 4.7 days real time for one, three, and five decade simulations, respectively which is considered a computationally efficient for modeling decadal landscape evolution. The utility of the SBM was demonstrated through an application to assess the performance of a sediment diversion in the Barataria Basin in Louisiana, USA. The model results demonstrate the importance of incorporating the impact of salinity and inundation effects on the resilience of marshes subjected to high rates of relative sea level rise. Further, the sediment reduction analysis confirms the critical impact of the Mississippi River sediment decline on potential land building from sediment diversions where 1.5%, and 3% annual declining rates show a reduction in net land gain due to Mid-Barataria Sediment Diversion operation of 30% and 50 %, respectively. This highlights the importance of considering the Mississippi River sediment supply decline in restoration projects’ planning and specifically, sediment diversions.

Evaluating land suitability for kemiri (Aleurites moluccana) as a multi-purpose tree species in community agroforestry land within Langkat District, North Sumatra

Evaluating land suitability for Aleurites moluccana in community agroforestry land within Langkat District, North Sumatra, is crucial for promoting sustainable development, enhancing livelihoods, and preserving ecosystems while honoring local traditions and cultures. The primary objective of this research was to evaluate and map the land suitability for A. moluccana within Langkat District, located in North Sumatra, Indonesia. To gather the necessary data, this study employed a survey method, involving the collection of soil samples from ten distinct land units within the field. The assessment of land suitability was carried out using the matching method. Geographic Information System (GIS) technology was utilized to create maps illustrating the distribution of land suitability, while a Global Positioning System (GPS) was employed to accurately record the coordinates of the collected soil samples. The findings revealed that within Gunung Ambat, Simpang Kuta Buluh, Rumah Galuh, and Telagah Village, the actual land suitability classes for A. moluccana were classified as moderately suitable (S2) and marginally suitable (S3). The prevailing limiting factors in this region were temperature (tc) and the characteristics of the root zone medium (rc). Consequently, this influenced the potential land suitability classes for A. moluccana, resulting in classifications ranging from highly suitable (S1) to moderately suitable (S2) and marginally suitable (S3). By implementing land suitability evaluation for A. moluccana in community agroforestry land, promoting sustainable land use, enhancing livelihoods, and conserving natural resources.

Tef [&amp;lt;i&amp;gt;Eragrostis tef (Zucc.) Trotter &amp;lt;/i&amp;gt;L.] is a most important cereal crop in Ethiopia in terms of production, consumption and cash. The study was carried out to investigate grain yield stability and genotype by environment interaction for 18 genotypes conducted in the potential high land areas of Western Oromia, Ethiopia for two consecutive years (2020 to 2021) using Randomized Complete Block Experimental Design with three replications. The study of variance for grain yield using the AMMI model indicated highly significant variation for genotypes, environment, and genotype-environment interactions. Environment accounted for 18.7% of the variance in grain yield, 17.9% for genotypes, and 61.5% for genotypes. The first IPCA component accounted for 47.9% of the interaction effect and revealed the two models were fit. Genotypes G15, G10, G4, G1, and G3 had the lowest AMMI stability value (ASV), indicating stability; genotypes G16, G14, G9, G7, G2, and G5 had the highest ASV value, indicating instability. From over all analysis genotype G1 and G3, showed a high mean grain yield, lowest GSI, ASV and stable compared to other genotypes in the study. As a result, G1 and G3 were identified as the best genotypes for future breeding programs and potential release in Western Oromia, Ethiopia&amp;apos;s highlands.

Modelling land and water based movement corridors in the Western Mediterranean: a least cost path analysis from chalcolithic and early bronze age ivory records

The transportation of Chalcolithic and Early Bronze Age ivory raw materials and artefacts across the Mediterranean has been in the focus of archaeological research for over a century now. However, tracing the flow of ivory has mostly been restricted to traditional theoretical models of raw materials distribution deriving from socio-culturally centred considerations. Environmental conditions, potential transportation networks and dissemination routes have not yet been considered decisive for the spread of ivory raw material from the African shores and the eastern Mediterranean towards the Iberian Peninsula. Implementing computational environmental and archaeological modelling, we present a fully reproducible quantitative approach to estimate potential communication and transportation networks based on environmental covariates. We deploy a Network Analysis model and a predictive model based on Least Cost Path density to propose a potential land- and sea-based movement corridor for the western Mediterranean Basin that could have enabled the cultural spread of resources during the 3rd and 2nd millennia BC. Using the presented model and the open-source data underlying the analyses, distribution patterns of multiple material resources from different chronological subsets or regions can be developed, which will contribute to understanding prehistoric human patterns across the Mediterranean.

The Influence of Land Subsidence on Risk of Constructing 150 kV Transmission Tower for South Sumatra – Bangka Belitung Interconnector

Transmission system is one of the national essential objects and should be reliable when functioning. Moreover, disturbances in transmission system can lead to disruption of the service function. A common risk to the reliability of electric distribution is land subsidence on transmission tower. Furthermore, the 150 KV interconnector of South Sumatra-Bangka Belitung (Sumsel-Babel) is located in the coastal area of Banyuasin Dua sub-district, South Sumatra. This area is a river delta with peat and clay soil structures and is prone to land subsidence. Therefore, this research aimed to identify environmental factors that affect land subsidence and cause risk to transmission tower. In the context of this research, Copras (Complex Proportional Assessment) and MCSA (Multi Criteria Spatial Analysis) were used for parameter weighting and risk assessment of tower location, respectively. The results of an expert survey to assess risk of potential land subsidence at tower location showed five parameters, namely, land use, distance to waters or potential flooding, land slope factor, soil type, and conus value. Individual parameters were weighted quantitatively and qualitatively based on the opinions of construction experts. Specifically, the qualitative method was performed by weighting based on criteria and sub-criteria, which were analyzed using Analytic Hierarchy Process (AHP). On the other hand, spatial analysis of locations at risk of land subsidence was conducted using GIS software. Based on the assessment results obtained, land use criteria had the largest weighting influence of 0.340 and the smallest weighting on the cone value was 0.08. Finally, tower location that are most at risk of land subsidence are on peatland, near water, and clay soil.

Algorithm for Evaluating the Difficulty of Land Consolidation Using Cadastral Data

Optimum planning and effective land consolidation, widely discussed by contemporary authors, is a response to the perceivable need to modernise global agriculture to ensure the community’s food security and create steady, sustainable development in rural areas. Adequate leveraging of agricultural policy instruments requires setting a correct strategic direction, including allocating available funds and considering the technical feasibility of the adopted assumptions. The selection of relevant methods to ensure the efficient and complete accomplishment of the anticipated results should follow a rational analysis of the actual work complexity. This paper presents an innovative, proprietary method for evaluating the difficulty of potential land consolidation using a standardised cadastral data set. The designed tool, which relies on automated algorithms applied in a GIS environment, provides accurate data describing the expected land consolidation complexity at individual stages of the procedure. Detailed and current information on land ownership, use, and farm geometry processed using efficient spatial and statistical analysis methods provides transparent and unambiguous results. The proposed solution was used in developing the difficulty assessment of land consolidation in 58 villages of the Strzyżów district in southeastern Poland.

On the macroecology of rarity and vulnerability to extinction in terrestrial mammals

Understanding the interplay between rarity and vulnerability in the decline and extinction of species is a major challenge for modern conservation biology. In addition to traditional approaches, answering this question necessarily requires integrating new methodologies and information on species' life-history traits and responses to environmental stressors. Here we use data for over 4000 mammal species to: (1) assess which forms and levels of rarity are most represented across current IUCN threat categories; (2) test whether interspecific variation in vulnerability is more closely linked to intrinsic traits related to their rarity, or to extrinsic factors related to anthropogenic pressures; and (3) identify geographical areas where species with high potential vulnerability are particularly common and assess their overlap with forecasts of land cover change. To achieve these goals, we model the directional influence of life-history traits related with rarity and extrinsic correlates on vulnerability. Our results confirm the strong link between rarity and vulnerability within mammalian orders. A model encompassing the three main rarity traits (i.e. range size, population density, and habitat breadth) correlates with vulnerability, despite not being directly correlated with population density. Recent habitat changes (within the past 35 years) did not show a direct relationship with vulnerability, but the contractions in range size reveal a more complex long-term effect on species vulnerability. Given the current scenario of limited conservation resources, we anticipate that knowledge about the characteristics most associated with vulnerability, coupled with mapping species possessing these traits and facing potential future land changes, can facilitate the development of more precise and effective conservation strategies aimed at preventing species extinctions.

Suitability for pepper plants are S3 nfx. While the actual land suitability on the type of Typic Sulfaquents (SPT 2) inhibiting factor is the low pH, nutrient availability, and the depth of the actual land sulfidik. Suitability for pepper plants are N-x. Recommendations for improvements in SPT 1 and SPT 2 is water regulation, liming and fertilizing N, P, and K with the processing level is medium to high, then the suitability of potential land for pepper plants in SPT 1 to be fit while on SPT 2 appropriate to marginal

Promoting equity in the Conservation Reserve Program across the southeastern US

Black and female landowners, two of the largest groups of underserved landowners in the southeastern US, have considerably less land enrolled in the US Department of Agriculture's Conservation Reserve Program (CRP) than White and male landowners. The reasons for this discrepancy are complex and interrelated. Previous studies approached different facets of this problem using a variety of methods and analyses. Here, we conducted a synthetic literature review that demonstrates how the intertwined ecological, economic, and cultural concerns of underserved landowners influence their decisions about potential land conversion in the context of CRP requirements. Other studies have rarely considered such relevant factors as the sociocultural importance of land to underserved populations or the links between the limited participation of these groups in the CRP and historical racism and sexism in land management industries and agencies. Explicitly addressing these issues will help promote conservation equity in the CRP and other conservation programs.

Optimization of land-use pattern based on suitability and trade-offs between land development and protection: A case study of the Hohhot-Baotou-Ordos (HBO) area in Inner Mongolia, China

Determining comprehensive land-use suitability is crucial for effective zoning management. However, limited research on land-use multi-suitability and the trade-offs between land development and protection hinder optimal environmental management. This study focuses on the Hohhot-Baotou-Ordos (HBO) area in Inner Mongolia, China, known for its unique geographical attributes, including abundant energy resources, potential arable land, and vulnerable ecological environment. The objective is to determine comprehensive land-use suitability for ecological protection, agricultural production, and urban construction, while addressing the trade-offs involved in land-use multi-suitability. Multi-scenarios were conducted based on multi-suitability using quantitative indicators, such as per capita space occupancy, patch density, and conductance index. The most suitable scenario, identified through these comparisons, was subsequently optimized for the HBO area by addressing land conflict zones using the InVEST model. The results revealed that: (1) Extremely suitable areas for ecological protection, agricultural production, and urban construction accounted for 47.75%, 18.19%, and 8.61% of the HBO area, respectively, indicating significant potential for ecological conservation. (2) Trade-offs were categorized into six scenarios based on land-use multi-suitability. The ecological-agricultural priority scenario demonstrated reasonable space allocation, the highest landscape agglomeration and connectivity, making it the most suitable option for optimizing the land-use pattern. (3) The optimized zoning delineated the ecological protection red line (EPR), which accounted for the highest percentage at 40.71%, while the urban reserve area (URA) was minimal, constituting only 1.28%. The primary goal of zoning management is to curb urban expansion and alleviate ecological degradation through effective strategies. Consequently, regulatory strategies focusing on management zoning were proposed. Overall, this study developed a comprehensive index system for land-use suitability, providing a method for balancing land development and protection. The findings offer a scientific reference for sustainable development in the HBO area and other regions with similar natural environmental backgrounds.

Land tenure conflicts in forest areas: obstacles to rejuvenation of small-scale oil palm plantations in Indonesia

Purpose This study aims to investigate the problems small-scale oil palm plantations in Indonesia’s forest areas face and the government policies addressing them. Design/methodology/approach Survey and data collection were used to determine the socioeconomic, environmental, legal and governance problems related to the development of smallholder plantations. Information was obtained from the respondents via a rapid rural appraisal approach. Findings The potential land for potential participants in the community oil palm rejuvenation programme is a forest area of 1,628,749.60 ha. Owing to its legal dimensions and unsustainable land management, the rejuvenation regulatory programme has not reached independent farmers. Research limitations/implications The use of plantation space beyond its designation hinders the government’s goal of accelerating the rejuvenation programme. The problems regarding the accumulation of forest area result in low achievement of the annual rejuvenation target in Riau Province (21%–25%). The authors present solutions to resolve land ownership conflicts and implement strategic policies to ensure the sustainable development of such plantations. Originality/value The authors introduce a conflict–resolution model for small-scale smallholder oil palm plantations to resolve the problems of forest area claims unaddressed in the Indonesian Job Creation Law. Land conflict resolution is categorised into five typologies: oil palm plantations with business permits; those without a forestry permit and subject to administrative sanctions; business activities in forest areas without forestry permits; resolving non-conformities in the progress of land or management controlled and used in forest areas prior to their designation by removing land parcels through modifying the forest area boundaries; and the settlement for farmers without cultivation registration certificates but have established plantations and whose land tenure can be proven.

Analysis of land use change on flood discharge of Bengawan Solo Upstream sub-basin

Abstract This study investigated land use changes of Bengawan Solo Upstream sub-watershed impact toward flood discharge between year 2015 and year 2019. The daily rainfall intensity was calculated statistically by using analysis frequency, and effective rainfall was acquired by compensation of potential storage and land use. Runoff discharge was calculated using the Nakayasu and the Soil Conservation Service method, while base flow discharge calculated using equation suggested by Hydrograph Synder Synthetic Gama-1. Land use change is represented by curve number (CN) value for year 2015 and year 2019 at values of 78.11 and 78.07, respectively. Decline of CN value was caused by surge of vegetation land area. Agricultural land CN value was not much different from settlement CN value. Overall, flood discharge that occurred plummeted between year 2015 and year 2019, although it was not significant. Decrease in flood discharge corresponds to decrease in CN value. Decline of CN value as much as 0.05 % yielded decrease of flood discharge as much as 0.16 % until 0.22 % related to return period.

Changes of physiological traits on red chili pepper (Capsicum annum L.) exposed by short-term waterlogging

Abstract Tropical riparian wetland known as non-tidal lowland is potential land for agriculture, especially for vegetable cultivation such as red chili pepper (Capsicum annum L.). Transitional period (dry to rainy season) has a chance for red chili pepper cultivation in the field (at low tide conditions), but has risk of experiencing dynamic water table to waterlogging in early rainy season. The aim of this research was to determine the effects of physiological traits of red chili pepper exposure on short-term (4 days) waterlogging. This study was done at the Tropical Crop Science Laboratory, Kagoshima University, Japan. The experiment was designed as a completely randomized factorial design. The first factor was control/field capacity and waterlogging (entire growing media was submerged). The second factor was chili variety, consisting of Laris and Romario. Treatments began 14 days after transplanting, lasted four days, then followed by seven days of recovery. The results of this study showed that there were changes in photosynthetic characters between before waterlogging, after waterlogging and after recovery time, between control and waterlogging, and also between Laris and Romario. Photosynthetic and transpiration rates decreased sharply under waterlogging in after waterlogging, but increased in after recovery period on Laris, opposite on Romario. Changes occur were associated with the decline in stomatal conductance and chlorophyll fluorescence as a response to waterlogging stress. Laris as a resistant variety has the ability to recover under short-term stress conditions, so it needs to be further developed for cultivation in tropical riparian wetlands.

Application of GIS &amp;amp; RS in Rainwater Harvesting for an Arid Region

In dry areas with variable rainfall, water shortages severely affect the livelihoods of local populations. Rainwater harvesting from land sites and roof-tops is a readily available solution to this problem. This study presents a GIS &amp; RS-based methodology to identify potential land sites and roof-top rainwater harvesting potential using easily obtainable and freely available data. Slope, land cover, soil, and drainage maps were used to identify suitable rainwater harvesting land sites, which were further analyzed for surface runoff using the curve number method. This research also incorporated obtainable socio-economic factors in identifying the suitable locations of dams considering the implementation stage. Based on the proposed criteria, 44 suitable locations for dams were identified and validated using a validation map and Google Earth images. CROPWAT model analysis revealed that paddy water demand in Batticaloa would increase threefold if all available land for paddy cultivation was utilized. Therefore, abandoned lands can be utilized by erecting dams at those identified locations. Analysis of Google Earth images also revealed that roof rainwater harvesting would be sufficient to meet the basic water demand in the area. This study demonstrates that rainwater harvesting can be an effective strategy for addressing water scarcity in dry areas.
