Abstract The use of biomass as a potential energy source has both advantages and disadvantages. Biomass is a potential source of fuel energy that provides economic and environmental benefits such as less expensive and less energy intensive production, carbon sequestration and soil preservation. However, the main concern associated with biofuels is that land needed for food will be used for biofuel crops. One potential solution is the use of marginal lands which are not suited for food production. Marginal lands generally refer to the areas not only with low production, but also with limitations that make them unsuitable for agricultural practices and ecosystem functions. This can be due to various forms of land degradation such as pollution, surface exploitation of mineral resources, erosion, overexploitation and others. We used remotely sensed data, environmental data and field survey data to identify possible marginal lands in Serbia. All gathered data was transferred to GIS in order to create maps and database of potential marginal lands which could be used for biomass production.

Full textAbstract:
Suitable lands for the steppe marmot are dry meadows and clear beams (without woody vegetation), which make up to 20 % of the territory of the steppe forest-hunting zone. Suitable lands for this species are large enough in area. It was found that with the excess of the optimal number, the intensity of reproduction of the species decreases, some animals move to less-suitable or even unsuitable lands causing increased animal mortality. Re-acclimatization of the species is carried out mainly by game husbandries, which have released more than 2330 individuals since 1991. The inclusion of the steppe marmot into the Red Book of Ukraine will destroy the possibilities of re-acclimatization.

Full textAbstract:
The existing Land Use Capability Classification for India is almost the true copy of United States Department of Agriculture Land Use Capability Classification system with very few minor changes; and thus it is mainly based on the Agro-economic structure of USA. As a result. many fertile and productive lands of India, which are highly economic to cultivate, comes under the class "Not Suitable for Agriculture", e.g. Tea Gardens of India and fertile cultivable lands on hill slopes. Further the factors considered in determination of Land Capability Class, have not been assigned specific weightage and contribution, and this might lead to subjectivity in determination of land class. Moreover the Indian Land Use Capability Classification divides the cultivable lands into two groups, suitable for cultivation and not suitable for cultivation, which is not justified under the existing cultivation conditions in India. The proposed Land Use Capability Classification system eliminates the dividing line between the land suitable and not suitable for cultivation; and recommends all lands which are economical to cultivate as Suitable for cultivation. In the proposed pattern of land classification, many factors have been considered and all these factors have been given a weighatge on marks basis and this helps in clear and distinct contribution of these factors in land class determination. In the proposed Land Use Capability Classification system, the class of land only denotes the relative productivity of land and not its suitability and unsuitability for cultivation.

Full textAbstract:
Understanding, analysis, monitoring and modelling of urban growth evolution as a major driving force of land use, especially in developed countries, is of great importance for land managers in the process of development. This research aims to analyse the spatial modelling of urban expansion using modern technologies - Delphi and Analytic Hierarchy Process (D-AHP) hybrid model and Geographic Information System (GIS) technique for Land-Use Assessment. These techniques are used to detect the most suitable and unsuitable areas in the Msila zone. By engaging residents and experts to choose criteria for analysing urban expansion, the study showed that 80.75% of total area represent suitable lands for expansion and around 19% represent unsuitable lands. By reading the results of the study, it is clear that the total suitable lands are located in the southwestern side of the city.

Full textAbstract:
Land evaluation for irrigation is the process of predicting land use potential on the basis of soil attributes. The Food and Agriculture Organization (FAO) framework for land suitability evaluation is the most commonly used and is based on the biophysical properties of lands. The FAO framework method for land suitability application Boolean approach that has been criticized by some researchers. Because the Boolean representations ignore the continuous nature of soil and uncertainties in measurement and also its inability for overcoming problems related to vagueness in definition and other uncertainties, fuzzy set methodologies have been proposed. In the present study, the qualitative land suitability evaluation for sprinkler irrigation using parametric-based FAO learning and fuzzy inference system was carried out in an area of 5175 ha in Northwest Iran. By overlaying the layers (soil texture, soil depth, lime, electric conductivity, drainage, and slope) and use of spatial data modeler in ArcGIS 9.3, land evaluation maps for sprinkler irrigation were provided for the area under study. Results showed that based on the parametric approach, 1598 ha of the study area were classified as highly suitable (S1 class) for sprinkler irrigation; the area of highly suitable lands in the parametric method was about five times the area of highly suitable lands obtained through the fuzzy method. In addition, the two methods were completely different in determining moderately suitable lands (S2). Accordingly, 787 ha in the area was moderately suitable using the parametric method, which was about two times that obtained through the fuzzy method. This showed the significant difference between two methods applied to evaluate the lands. Moreover, fuzzy approaches accommodate the continuous nature of some soil properties and produce more intuitive distributions of land suitability indexes.

Full textAbstract:
In any region of the globe, the cultivation of industrial crops, including hemp, imposes certain conditions related to relief, climate, hydrology, or soil. The interrelations between these factors lead to differentiations regarding the establishment of cultivation zones and implicitly in terms of productivity. This study aimed to identify suitable areas for hemp cultivation and generate favorability maps in western Romania, based on GIS and MCDA techniques. Ten factors, significantly important for hemp cultivation, related to relief, climatic conditions, soil, and human intervention were considered. Following spatial analyses using the Weighted Overlay Analysis (WOA) method, the territory was classified into four zones: Zone I, with highly suitable lands (26%), located in the western half, overlapping with plain areas and river valleys; Zone II, with moderately suitable lands (28%), located in regions of high plains and hilly areas; Zone III, with marginal lands (3%), located in some depression areas, hilly areas, or at the contact with pre-mountainous areas; Zone IV, with unsuitable lands for hemp cultivation, in mountainous areas, under restrictive environmental conditions. The obtained results can be used in land management strategies or by farmers for estimating available land resources.

Full textAbstract:
Background Essential oils are natural products of aromatic plants with numerous uses. Essential oils have been traded worldwide and utilized in various industries. Indonesia is the sixth largest essential oil producing country, but land degradation is a risk to the continuing extraction and utilization of natural products. Production of essential oil plants on degraded lands is a potential strategy to mitigate this risk. This study aimed to identify degraded lands in Indonesia that could be suitable habitats for five wild native essential oil producing plants, namely Acronychia pedunculata (L.) Miq., Baeckea frutescens L., Cynometra cauliflora L., Magnolia montana (Blume) Figlar, and Magnolia sumatrana var. glauca (Blume) Figlar & Noot using various species distribution models. Methods The habitat suitability of these species was predicted by comparing ten species distribution models, including Bioclim, classification and regression trees (CART), flexible discriminant analysis (FDA), Maxlike, boosted regression trees (BRT), multivariate adaptive regression splines (MARS), generalized linear models (GLM), Ranger, support vector machine (SVM), and Random Forests (RF). Bioclimatic, topographic and soil variables were used as the predictors of the model habitat suitability. The models were evaluated according to their AUC and TSS metrics. Model selection was based on ranking performance. The total suitable area for five native essential oil producing plants in Indonesia’s degraded lands was derived by overlaying the models with degraded land locations. Results The habitat suitability model for these species was well predicted with an AUC value >0.8 and a TSS value >0.7. The most important predictor variables affecting the habitat suitability of these species are mean temperature of wettest quarter, precipitation seasonality, precipitation of warmest quarter, precipitation of coldest quarter, cation exchange capacity, nitrogen, sand, and soil organic carbon. C. cauliflora has the largest predicted suitable area, followed by M. montana, B. frutescens, M. sumatrana var. glauca, and A. pedunculata. The overlapping area between predictive habitat suitability and degraded lands indicates that the majority of degraded lands in Indonesia’s forest areas are suitable for those species. Conclusion The degraded lands predicted as suitable habitats for five native essential oil producing plants were widely spread throughout Indonesia, mostly in its main islands. These findings can be used by the Indonesian Government for evaluating policies for degraded land utilization and restorations that can enhance the lands’ productivity.

<p><strong>Abstract.</strong> The ever-increasing development of the cities and the growth of population have led to an uncontrollable sprawl of spatial structure of the cities. Hence, sustainable development and organizing of land-use planning are always an important concern of decision makers. Zanjan city, due to the existence of physical limitations and environmental issues, needs precise planning regarding city development. The aim of this study is to determine the sustainable development direction of urban development while taking the social, economic, and environmental perspectives into account. To determine suitable lands for future developments, totally 10 criteria in three groups, specifically social, economic and environmental were employed. In order to analyse the considered criteria in this study, experts’ opinions were gathered to be used in determining the weights of the criteria using the analytical hierarchical process (AHP). Then, the yielded weights were applied to the criteria in a geographical information system (GIS) through spatial analyses. Finally, the technique for order of preference by similarity to ideal solution (TOPSIS), as a multi-attribute decision making (MADM) method, was utilized to extract the priority of suitable lands for city development. The results show that the most suitable lands for the purpose of future developments are located in the north-eastern and eastern parts, after which are the lands located in the north-western parts. In addition, 15 percent of city development since 2005 has occurred in unsuitable lands. Moreover, to evaluate the results, TOPSIS outcomes were compared with the weighted sum model (WSM) approach.</p>

Full textAbstract:
This study spatially estimated degraded lands in Indonesia that have limited functions for food production, carbon storage, and conservation of biodiversity and native vegetation and examined their suitability to grow biodiesel species (Calophyllum inophyllum, Pongamia pinnata, and Reutealis trisperma) and biomass species (Calliandra calothyrsus and Gliricidia sepium). Results showed ~3.5 million ha of degraded lands potentially suitable for these species in Indonesia. With the all-five-species scenario, these lands had the potential to produce 1105 PJ year−1 of biomass and 3 PJ year−1 of biodiesel. With the biodiesel-only-species scenario, these lands showed the potential to produce 10 PJ year−1 of biodiesel. Despite this energy potential, however, the land sizes were too small to support economies of scale for biofuel production. The study findings contribute to identifying lands with limited functions, modeling the growth of biofuel species on regional lands, and estimating carbon stocks of restored degraded lands in Indonesia.

The appropriateness of agricultural land necessitates regular accurate assessment and evaluation of fertility. Land Suitability Analysis (LSA) is one of the accurate evaluations to maintain & monitoring quality of the agricultural land. It is a necessary procedure to investigate the site suitability for any agricultural purpose. This study evaluates the land quality and rice production capacity in the Sivasagar District of Assam, India. This study used a multi-criteria Analytical Hierarchy Process (AHP) in remote sensing & Geographic Information System (GIS) software ArcGIS to evaluate the major factors influencing rice cultivation, including soil type, water availability, and meteorological parameters. This study classifies the suitability classes into four categories as per the procedure set by the Food and Agricultural Organization (FAO); highly suitable, moderately suitable, marginally suitable, and not suitable. Due to the differences among the rice crop conditioning agro-ecological parameters, only 13 km2 of lands accounting 0.81% of total lands are highly suitable for the cultivation of rice, which is primarily determined by water availability considerations, land use and land cover (LULC), and the Normalized Difference Vegetation Index (NDVI). With 21.66 km2 of available waterbodies, good groundwater prospects, an annual average precipitation of 185 cm to 214 cm, and a land surface temperature of 27.32°C to 32.63°C, projected production and suitability are declining due to inefficient management practices. Farmers in the study area must use more advanced strategies to gain greater accessibility to water resources, particularly those agricultural lands that are classified as moderately or marginally suitable.

Land suitability assessment is essential for planned land management strategies aimed at preserving soil and increasing productivity while ensuring sustainable agricultural production. Land degradation resulting from poor land management and fallowing practices typically leads to low land productivity in Iraq. To maintain agricultural productivity in the targeted area, agricultural requirements must align with available resources through land suitability analysis. In the northern region of Basrah Governorate in Iraq, the study focused on integrating GIS-based land suitability analysis with the fuzzy-analytical hierarchy process (F-AHP) approach. The analysis revealed varying suitability categories throughout the study area, with the largest proportion of unsuitable areas found in category N2, covering 31,202.36 hectares (37.76%), and category N1, currently unsuitable, covering an area of 19,956.24 hectares (24.15%). On the other hand, the moderately suitable category (S3) covered 8,297.26 hectares (10.04%), while the moderately suitable category (S2) covered 23,177.79 hectares (28.05%) of the total study area. No highly suitable lands were identified. The key determining factors for the suitability of lands for wheat cultivation were high values of electrical conductivity, carbonate minerals, bulk density, and low organic carbon content. Most agricultural lands are being used in a manner that contradicts their suitable potentials in the study area. Therefore, the pattern of agricultural land use needs to be adjusted based on their current potentials to reduce soil degradation.

Full textAbstract:
Optimizing soil—crop—landscape occurrence is essential for sustainable intensification and food security, but little work has been done to evaluate these parameters on Tribal lands. The objective of this study was to develop first ever high-resolution crop suitability maps and compare two established crop suitability models for their ability to optimize soil resource management of the Quapaw Tribal lands. We built on previously developed continuous soil properties maps for 22,880 ha of Quapaw Tribal lands that used a digital elevation model and a fuzzy-logic based data mining approach to calculate and evaluate the Dideriksen and Storie crop suitability indices. Suitability index results were evaluated against observed yield (n ≥ 130,000) within the study area. Results showed that the observed yield was positively correlated with the Storie suitability index (Spearman rho = 0.16, p < 0.01), but not the Dideriksen index, suggesting the Storie index is more appropriate than the Dideriksen for modeling crop suitability in this area. Additionally, very little (<13%) of the highly suitable soils in the Quapaw Tribal lands are currently used for crop production, suggesting potential yield gaps from the underutilization of highly suitable soils. Future research could improve estimates through the development of novel suitability indices for closing yield gaps and further improved sustainable intensification.

Background: Tea is an important economic crop in Yunnan, and the market price of premium teas such as Lao Banzhang is significantly higher than ordinary teas. For planting lands to promote, the tea industry to develop and minority lands’ economies to prosper, it is vital to evaluate and analyze suitable areas for premium tea cultivation. Methods: Climate, terrain, soil, and green cropping system in the premium tea planting areas were used as evaluation variables. The suitability of six machine learning models for predicting suitable areas of premium teas were evaluated. Result: FA+ResNet demonstrated the best performance with an accuracy score of 0.94 and a macro-F1 score of 0.93. The suitable areas of premium teas were mainly located in the southern catchment of LancangJiang River, south-central part of Dehong, a few areas in the mid-west of Lincang, central scattered areas of Pu’er, most of the southern western part of Xishuangbanna and the southern edge of Honghe. Annual mean temperature, annual mean precipitation, mist belt, annual mean relative humidity, soil type and elevation were the key components in evaluating the suitable areas of premium teas in Yunnan.

Cultivated reserved land resources are pivotal for achieving food security and sustainable agricultural development. However, existing research on these resources often grapples with issues such as the lack of current data and underutilization of available data. This study focuses on Haishu District in Ningbo City of China, an economically developed area, and uses the third national land survey data to identify potential agricultural and construction lands suitable for conversion to cultivation. Through the application of the limiting factor method and the Analytic Hierarchy Process (AHP), the results indicate that the potentials of reserved cultivated land and the reclamation potential of construction land in Haishu District are estimated at 503.07 and 1527.50 ha, respectively. These lands are primarily rated as generally suitable and marginally suitable for agriculture, suggesting a moderate overall quality of reserved cultivated resources. This study emphasizes the practice of surveying reserved cultivated land, to boost effective land management and strategic development.

Rapid and unplanned urbanization and haphazard infrastructure development causes pressure on the finite land resource and there is urgent need to preserve the arable land for food security. Land suitability analysis is a technique in which the land quality assessment is performed through interpretation of land properties for allocation of lands for particular use. The present paper attempts to conduct a land suitability analysis to determine the potential sites for agriculture land use in Sambhunath municipality of Saptari district. The criteria/ factors for the land suitability analysis were identified through literatures and modified in the local context through expert opinions and focus group discussions. The evaluation of agriculture land is accomplished using Analytic Hierarchy Process (AHP), Multi-Criteria Evaluation (MCE) and Geographic Information System (GIS). Agriculture suitability index was developed and optimized qualitatively through the strength, weakness, opportunity, and threat (SWOT) analysis. Finally, potential agriculture suitability index map is prepared. The analysis shows almost 3139 ha (29%) lands as 14 highly suitable and 3001 ha (28%) of moderately suitable agriculture land within the municipality. Almost all the suitable agriculture land is located at low land with flat terrain to gentle slope having high natural fertility and mainly in land capability classes I and II. The unsuitable and poorly suitable agriculture land is occupied in the undulating areas and hilly terrain of the Siwalik hill. The study found the GIS tool integrated with MCE-AHP useful in land suitability evaluation process and anticipated that it could act as the planning tool to allocate lands in land use planning for sustainable agricultural practices.

In the nineties of the last century due to the known economic stress experienced in this time in Russia there were more than fifty million hectors of arable lands withdrawn from the Russian agricultural turnover. There are more than one million hectors of such arable deserted lands in the Amur Region of the Russian Federation (The Far Eastern part of Russia). These arable lands have turned into deteriorating lands in abeyance being colonized by weeds and periodically attacked by fires. As a result of this, these promising agricultural lands, being used for the food supply and forage resources production, have lost their primary purpose of use. It has become a serious national economic problem. Nowadays there is a gradual inclusion of such arable lands into soya and wheat production. The conduction of agrochemical and geo-botanical research needed for suitability evaluation of such arable lands for soya and wheat species cultivation is to a certain degree very expensive and time-consuming procedure. Our research work suggests implementing resources-evaluating method which implies one-time route study in the period of mass flowering of plants and identifying the plants of the arable lands that have resource value. If the number of these plants exceeds eighty percent in relation to the whole species composition, then such arable lands are considered to be suitable for crop rotation. If this ratio is less than sixty percent, then it is necessary to take extra measures in order to reduce the number of weeds and woody plants on such arable lands.

Full textAbstract:
Porang (Amorphophallus oncophyllus L.) stands as a prominent agricultural product in Indonesia. As the demand for porang continues to grow, it becomes crucial to balance it with the expansion of suitable land for cultivation. The selection of appropriate land for crop planting requires a thorough analysis of land feasibility, commonly known as land suitability assessment. This study aims to evaluate land feasibility, identify limiting factors, and explore potential solutions for sustainable cultivation of porang in Sumberejo Village, Pasuruan, East Java. The research was employed by a matching method for land suitability assessment based on climatic, physical, and chemical data. The development of a land suitability map was achieved through the overlay of various stages using land characteristic information. The findings reveal that the residents' lands fall within the actual land classes of S3 (suitable marginal) and N (not suitable), with base saturation (nr3) and slope (eh) identified as the primary limiting factors. To improve the suitability of the selected lands, several recommendations were proposed, including the implementation of cover crops, terracing practices, and the addition of potassium-rich organic matter derived from bamboo waste. These recommendations have the potential to elevate the land class to S2 (suitable) and S3 (suitable marginal), thereby addressing the identified limitations and promoting sustainable porang cultivation.

Indonesia, besides being the country with the largest nickel reserves in the world, also holds the largest tin reserves globally in 2023. Meanwhile, in terms of production, Indonesia ranks second after China. Tin mining in Indonesia has led to serious environmental damage, illustrated by the numerous open pits and inadequately restored tin mining sites. The characteristics of soil in these post-mining lands generally include sandy texture, low pH, nutrient deficiencies, low organic carbon content, and low water holding capacity. This study aims to improve the soil chemical properties in post-mining lands by utilizing the KOMFABA technology, which consists of a mixture of compost and fly ash-bottom ash with appropriate dosages tailored to the type of crops to be planted, along with revegetation strategies involving suitable plant selections. The research methodology consists of field experiments to test the application of KOMFABA with various dosages and crop types, as well as a literature review to identify suitable revegetation strategies. The research result show that Indonesia holds tin reserves of 800,000 tons, making it the largest in the world, with a production of 74,000 tons, placing it second after China. Additionally, the results of KOMFABA testing demonstrate its effectiveness in improving soil chemical properties such as soil pH, organic carbon content, cation exchange capacity (CEC), nutrient content, and soil base saturation. The success of reclaiming post-mining lands also dependent on proper fertilization dosages and suitable plants selection.

Full textAbstract:
In the history of irrigated agriculture there are many cases when due to severe soil salinity the yield was so low that it did not justify the costs incurred for cultivation of crops. Such lands were classified as unsuitable and were left without use for crops. Lands from suitable ones turned into unsuitable ones and were also often left out of use for irrigated crops, thus, among the old irrigated land masses there were many fallow lands, fallow fields and other vacant lands. The growth of salinity of irrigated soils in the Central Asian republics in the last 30-35 years has become almost ubiquitous. Both old and new irrigation systems bear heavy losses from growing soil salinity. More often secondary salinization in irrigated soils begins to appear even at relatively deep groundwater (3.5-4) in the form of seasonal (during summer) spot salinization of soils on microrelief elevations, on spots of irrigated fields bare from cultural vegetation.

Full textAbstract:
Land evaluation is important for assessing environmental limitations that inhibit higher yield and productivity in tea. The aim of this research was to determine the suitable lands for sustainable tea production in the northeastern part of Bangladesh using phenological datasets from remote sensing, geospatial datasets of soil–plant biophysical properties, and expert opinions. Sentinel-2 satellite images were processed to obtain layers for land use and land cover (LULC) as well as the normalized difference vegetation index (NDVI). Data from the Shuttle Radar Topography Mission (SRTM) were used to generate the elevation layer. Other vector and raster layers of edaphic, climatic parameters, and vegetation indices were processed in ArcGIS 10.7.1® software. Finally, suitability classes were determined using weighted overlay of spatial analysis based on reclassified raster layers of all parameters along with the results from multicriteria analysis. The results of the study showed that only 41,460 hectares of land (3.37% of the total land) were in the highly suitable category. The proportions of moderately suitable, marginally suitable, and not suitable land categories for tea cultivation in the Sylhet Division were 9.01%, 49.87%, and 37.75%, respectively. Thirty-one tea estates were located in highly suitable areas, 79 in moderately suitable areas, 24 in marginally suitable areas, and only one in a not suitable area. Yield estimation was performed with the NDVI (R2 = 0.69, 0.66, and 0.67) and the LAI (R2 = 0.68, 0.65, and 0.63) for 2017, 2018, and 2019, respectively. This research suggests that satellite remote sensing and GIS application with the analytical hierarchy process (AHP) could be used by agricultural land use planners and land policy makers to select suitable lands for increasing tea production.

Abstract The U.S. Fish and Wildlife Service (USFWS) is responsible for reviewing the biological status of hundreds of species to determine federal status designations under the Endangered Species Act. The longleaf pine Pinus palustris ecological system supports many priority at-risk species designated for review, including five species of herpetofauna: gopher tortoise Gopherus polyphemus, southern hognose snake Heterodon simus, Florida pine snake Pituophis melanoleucus mugitus, gopher frog Lithobates (Rana) capito, and striped newt Notophthalmus perstriatus. To inform status decisions and conservation planning, we developed habitat suitability models to 1) identify habitat features that best predict species presence and 2) estimate the amount and distribution of suitable habitat across each species' range under current conditions. We incorporated expert judgment from federal, state, and other partners to capture variation in ecological settings across species' ranges, prioritize predictor variables to test in models, mitigate data limitations by informing the selection of pseudoabsence points, qualitatively evaluate model estimates, and improve the likelihood that experts will trust and use model predictions for conservation. Soil characteristics, land cover, and fire interval strongly influenced habitat suitability for all species. Suitable habitat was distributed on known species strongholds, as well as private lands without known species records. Between 4.7% (gopher frog) and 14.6% (gopher tortoise) of the area in a species' range was classified as suitable habitat, and between 28.1% (southern hognose snake) and 47.5% (gopher frog) of suitable habitat was located in patches larger than 1 km2 (100 ha) on publicly owned lands. By overlaying predictions for each species, we identified areas of suitable habitat for multiple species on protected and unprotected lands. These results have direct applications to management and conservation planning: partners can tailor site-level management based on attributes associated with high habitat suitability for species of concern; allocate survey effort in areas with suitable habitat but no known species records; and identify priority areas for management, land acquisitions, or other strategies based on the distribution of species records, suitable habitat, and land protection status. These results can aid regional partners in implementing effective conservation strategies and inform status designation decisions of the USFWS.

Full textAbstract:
Afforestation of agricultural lands may be a positive action in many cases. Especially, it is a beneficial feature for waterlogged soils, stony soils or for soils which are less fertile for any other reason and thus unsuitable for farming. Afforestation can be a very important action even in the agricultural landscape – afforested belts of agricultural land divide large farm blocks into smaller ones, or act as windbreakers and biological corridors. The value, quality and fertility of soil can be assessed in different ways. The study aims to determine the identification soil criteria of agricultural land which is suitable for afforestation. This evaluation process is based on Evaluated Soil Ecological Units (ESEU), in the Czech Republic known as BPEJ, database which is available for all agricultural land in the Czech Republic. The results are represented by a complete list of ESEU codes suitable for afforestation. The list of codes is supplemented by an explanation why such an ESEU code, representing a soil group with similar properties, is suitable to afforestation.

Full textAbstract:
The prairies and savannahs historically found in the Mixedwood Plains Ecozone have been largely converted into farmland, the dominant present-day land cover. Consequently, many species native to these grasslands have shifted to inhabiting suitable agricultural lands. More recently, agricultural intensification has led to the conversion of pastures and hay fields to annual crops, further removing habitat suitable for the persistence of grassland species. We quantified the shift from pasture and forage to annual crops as well as the dynamics among agricultural lands and other land covers in the Mixedwood Plains Ecozone, predicting biodiversity implications by providing a case study on Eastern Meadowlark ( Sturnella magna (Linnaeus, 1758)). The total agricultural land area changed little over the study period, but area of pasture and forage decreased while row crop area increased. The loss of agricultural lands to urbanization was partly offset by the conversion of forests and wetlands; however, the farmland gained was of lesser agricultural quality than the farmland lost. Declines in Eastern Meadowlark abundance correlated significantly with carrying capacity loss, suggesting that habitat availability is a limiting factor for this species. We highlight the importance of land management policies to minimize the impacts of land conversion on biodiversity and agricultural production.

Agricultural land is the most valuable resource of today because the issue of food security in the world community now comes first. Unfortunately, the ecological condition of lands suitable for agricultural use in Ukraine and the situation in the field of their use is constantly deteriorating. The quality of land resources is declining and approaching catastrophic levels. In this regard, the purpose of the study is to explore the main aspects of legal and environmental regulation of fertile land protection and to suggest ways to improve the protection and preservation of agricultural land. The main research method is the method of analysis, thanks to which the world experience in the field of environmental protection in general and the protection of agricultural lands was comprehensively analysed. The normative-legal acts of Ukraine, which regulate the issues of land use, as well as protection and preservation of agricultural lands, were analysed. The proposed mechanisms of environmental protection on the example of agricultural lands can be used to form targeted government programs.

The paper examines the concept of agricultural land as the main category of land in Ukraine, reveals the peculiarities of the legal regime and composition of the specified category. The composition of agricultural lands has been established. A general description of agricultural land and its area in Ukraine is given. The negative consequences that affected the legal regime of use and protection of agricultural lands are indicated. It was also established that the concept of land plot for agricultural purposes is absent in the legal framework, on the basis of which a proposal was made to supplement the Land Code of Ukraine with such a concept. It was established that the very concept of the legal regime of agricultural lands has a number of features that are inherent only to agricultural lands. In the process of the analysis and research of the regulatory legal framework of the main legislative acts of land law and the research of scientists, we proposed our vision of the concept of agricultural land, namely: "Agricultural land is land that, by its properties, is suitable for cultivation, production, storage, processing and sale of agricultural products, and can also be provided for scientific research and educational activities of interested subjects". The mentioned concept is proposed to be included in Article 22 of the Civil Code. It is clear that such a definition is complex but short, and for its further understanding it is also possible to add the Article, part 2 of Article 22 of the Civil Code of Ukraine, for the purpose of greater understanding. Also proposed is the following version of the concept of a plot of land for agricultural purposes - it is a plot on which agricultural activity is carried out or can be carried out, has appropriate boundaries, area and an owner (tenant) who has a document confirming the right of ownership. In order to eliminate the gap in land legislation, we propose to add part 3 of Article 22 of the Civil Code, which specifically establishes the concept of agricultural land.

The assessment of land suitability for a specific use is a vital part of land use planning and agricultural development. The basic feature of land suitability evaluation is the comparison of the requirement of land uses with resources offered by the land. A study was conducted to evaluate the land suitability for coconut cultivation in southern Karnataka with a prime focus on increasing the productivity of coconut by way of promoting its cultivation in areas which show high and moderate suitability, and restricting at marginally suitable areas. For this seven soil pedons were selected on the map of coconut-growing areas, delineated with the help of land resource map and report of Karnataka state, generated at 1: 2,50,000 scale by ICAR-NBSS & LUP, Bangalore and were located at Krishnarajapete, Arasikere, Beltangadi, Brahmavara, Hosadurga, Turuvekere and Gubbi representing the density of coconut-growing areas in different agro-climatic zones. Land suitability was evaluated following FAO [1] guidelines. Land suitability assessment of major coconut-growing areas of southern Karnataka indicated that Krishnarajapete and Arasikere have moderately suitable lands with moderate limitations while others have marginally suitable lands with severe limitations for coconut cultivation.

The article discusses ways to convert unsuitable saline lands into suitable ones using the “Carbon Dioxide Forming Utility Model” and the integrated use of desalinating biocomposites. A three-year study proved that among the 10 options studied, the best desalinating and restoring soil fertility turned out to be 10-9-8 and 7 options. In these options, the savings in wash water, respectively, were according to the option: 1.46 times; the amount of chloride and sulfate ions decreased: 55-54.2-52.4-51.5 %; cotton yield: 15.8-15.214.4-14.1c/ha yield increase was higher than the control variant. It was also determined on a scientific basis through the use of the “Carbon Dioxide Forming Utility Model” and the complex use of biostrains and immunocomposites for the successful origin of the neutralization process, the amount of harmful salts in the soil decreased, the absorption of phosphorus fertilizers by plants improved and the number of beneficial microorganisms in the soil increased, its structure improved. Also, the uniform distribution of macro and microelements in plants was balanced. By improving the neutralization and structure of the soil, degraded land was restored to fertile. The laws of balance were restored.

In Roman agrimensura, starting from the archaic period, there was a division of land areas: culta - meant fields suitable for tillage; inculta - unsuitable for grain crops. Culta were subjected to divisio, forming the category agri divisi. Inculta retained the status of Publicus, so they were not divisi. But the importance of these lands was important when organizing Ager Colonicus, since they created an opportunity for settlers to engage in farming and cattle breeding in addition to farming. Roman surveyors identified categories of such public lands. They could be used by the owners of nearby plots. Such lands were provided to new settlers for rent for vectigal. These were the relic lands (agri relicti) and the massif that made up the colony’s reserve (extra clusa). In addition, the remnants of the surveying - subsecivi (unoccupied centuries or its fragments) were also provided to the colonists for temporary lands. A “joint pasture” (compscuus) was often created on the segments. Also, on lease terms, the new settlers used the forest and pasture (silva et pascua). On all categories of land, ownership relations were formed within the boundaries of Ager Colonicus. As a result, the colonist’s economy acquired a complex character, which contributed to the prosperity of this new settlement.

According to the National Inventory of Anthropogenic Emissions, agriculture is one of the largest sources of greenhouse gas emissions, while the proper use of its potential can help mitigate climate change. The article provides a scientific basis for the models of climate projects that can be implemented on agricultural lands. It has been determined that the greatest complementarity to the baseline is provided by such climate solutions on agricultural lands as agroforestry, zero-tillage technologies, and restoration of degraded pastures. It has been established that among all resource-saving methods of managing agricultural lands, agroforestry has the greatest sequestration potential. A quantitative assessment of the areas on agricultural lands in the constituent entities of the Russian Federation suitable for the implementation of climate projects has made it possible to determine that the greatest potential for the implementation of climate projects on agroforestry will be in areas of arable land that have not been used for their main purpose for a long time, including those overgrown with trees and shrubs. A classification of the subjects of the federal districts of the Russian Federation was carried out from the position of favorable and unsuitable conditions formed in them on unused agricultural lands for the implementation of climate projects.

Vacant and abandoned land are important sources of endogenous urban development. Ahvaz, one of the largest cities in southern Iran, has undergone significant physical expansion. Consequently, identifying suitable land for new development is essential for urban authorities. This research aimed to identify vacant urban land in Ahvaz using UAV images. The identification process was based on two criteria: "Urban Morphology" and "Distribution Pattern," which guided the extraction of urban vacant lands. The methodology included standardized image processing, categorization of vacant spaces, and statistical analysis to ensure accuracy and reliability. The first step was to identify the location of vacant lands in Ahvaz using images. Next, suitable locations for infill development were categorized into 6 groups based on their number and area. The density and distribution of these spaces were then examined using the index of the shape of the vacant plots and the Kernel function. The findings revealed that the largest area of vacant land was categorized as "barren with vegetation." In terms of distribution patterns, zones 2 and 1 of Ahvaz city exhibited the largest and smallest vacant land areas, respectively. This indicates a correlation between urban development levels and the availability of vacant spaces, suggesting that more developed areas tend to have fewer vacant lands. Moreover, zone 2 had the largest amount of vacant land in the town, followed by zones 8 and 6.

The recultivation of the agricultural land has the character of a planning event, inasmuch as its nature and normative justification corresponds to the established technological standard for carrying out such. In a specific aspect related to the peculiarities of this process on agricultural lands, the legal regulations focus mainly on some details related to potential construction on these lands, while at the same time preserving, respectively improving their productivity. Within the meaning of Article 12, paragraph 3 of the Law on the Protection of Agricultural Land, the use of recultivated agricultural land for non-agricultural purposes is possible by changing its purpose. According to the text of Article 14, Paragraph 1 of the Law on the Protection of Agricultural Land, the construction of agricultural land from first to sixth category is carried out only after removal of the humus layer, which, according to the provisions of Article 15, paragraph 1 of the Law on the Protection of Agricultural Land, is used for reclamation of disturbed terrains. If the terrains do not have the characteristics of disturbed, the humus layer is used to improve the productive qualities of the low-productive lands. The normative requirements regarding the disturbed agricultural terrains and the necessity to carry out recultivation measures on them are regulated in the text of Article 3, paragraph 1 of Ordinance No 26 on rehabilitation of damaged terrains, improvement of low-productive lands, seizure and utilization of humus layer. Reclamation is necessary and feasible: a / where the affected terrain will be used for agricultural purposes; b/ when the surface elevation is equal to the height of the neighboring properties; c / when road accessibility to the land subject to recultivation is ensured. Besides the above mentioned requirements, the requirement for ensuring the sustainability of the recultivated terrain is regulated. This resistance is associated with ignoring the possibility and the danger of collapsing, sliding and sliding, and when creating terraces, their slope must ensure the stability of the earth masses. The text of Article 4 of Ordinance No 26 regulates the two-stage process of recultivation, which differentiates two groups of reclamation: technical and biological. Technical recultivation covers a set of events that start with cleaning and preparation of disturbed terrain, seizure and transport of earth masses, alignment and landscaping. When the terrain has acquired a final appearance, the norm requires the actual, subject of the recultivation activity - transportation and spreading of the humus layer. According to the regulation of art. 2, para 3, item 2 and item 3 of Ordinance № 26, suitable materials for the creation of an upper layer for reclamation of damaged terrains, which must have a humus layer thickness of 30/35 cm, are also, the appropriate horizon of the soil profile, which is inhabited by small microorganisms and the deeper layers to be treated. The use of such materials is the subject of the second stage of the reclamation process - the stage of biological recultivation, which is classified in the text of Article 4, item 2 of Ordinance No 26 as a complex of agro-technical, agrochemical, technological and meliorative activities for restoration of the productivity of reclaimed areas for a 5-year period after the technical reclamation.

Abstract. The cultivation of bioenergy plants in fertile, arable lands increasingly results in new land use conflicts with food production and cannot be considered as sustainable. Marginal lands have been frequently considered as potential alternatives for producing bioenergy from biomass. However, clear definitions and assessment methods for selecting marginal lands and for calculating potentials are still widely missing. The project “SEEMLA” aims at triggering the exploitation of currently underused marginal lands for biomass production for energy purposes. Study sites have been selected in different European countries: Germany, Greece, and Ukraine. The selected sites represent a wide variety of different types of marginal lands. Based on a soil assessment set given by the Muencheberg Soil Quality Rating (SQR) system potentially “marginal” sites have been investigated. The SQR system allows for clearly distinguishing between soils of higher and lower quality. Soils with SQR scores below 40 are regarded as “marginal”. They can be classified into different groups with regard to the importance of soil hazard indicators as evaluated by the SQR approach. The calculated SQR scores correlate significantly with biomass yields of bioenergy plants. Further, the SQR method was adapted for use in a GIS study on marginal-land potentials in Europe. Thus, 46 % of the investigated European area could be classified as “marginal” with SQR scores below 40. From that area 22.6 % can be considered as potentially suitable for producing renewable resources after eliminating protected sites or other places not suitable for any kind of land use. Taking the ecological demands of selected bioenergy plants into account it is possible to give first preliminary recommendations for regional crop cultivation. It can be concluded that Europe offers a large potential for renewable resources from marginal sites. However, the implementation into practice is often impeded by missing or varying policies and regulations. A proper implementation needs clear regulations and also incentives for farmers at the European level.

Full textAbstract:
The high productivity and quality of the harvested prawn are the main objectives of the intensive giant freshwater prawn (GFP) culture. Therefore, the breeding program to create a superior strain of the prawn has been conducted in several countries to support prawn farming. The purpose of this study was to evaluate the productivity and female reproductive performance of the GFP superior strains, namely the selected GI Macro (GI) and Siratu (SR) in the three farming conditions. The GI has resulted from an individual selection program based on standard length and maturation level characters. The multi-location test was conducted in the grow-out phase for 90 days at the three locations based on altitude, namely low-lands (in Subang, 10-25 m above the sea level, asl), medium-lands (in Ciamis, 70-100 m asl), high-lands (in Kuningan, 700-800 m asl). The growth characters consisting of total length/TL, standard length/SL, and body weight/BB of GI and SR were not significantly different, both on the Low, medium, and high lands ponds. The survival rate of the GI (87,3±7.26%) was significantly higher than the SR (71.0±0.08%) in the medium-land pond. In the high-lands pond, the survival rate of the SR (72.33±0.32%) was significantly higher than the GI (55.8±6.27%). Meanwhile, the productivity and percentage of the gravid female in the low-lands pond were not significantly different. The data suggested that the selected GI Macro is a location-specific genotype, more suitable to be cultured in the low and moderate-lands pond with warm temperature characteristics. Keywords: freshwater prawn, growth, multi-location, reproduction
