Rapid population growth is a global concern, particularly in developing countries.  It has become challengeable in the backdrop of the availability of agricultural land. The coastal areas of Ampara District are densely populated and that during the post tsunami and post war periods, the new settlements increased rapidly in these areas. This new phenomenon caused a series of problems including the demand for agricultural areas being increased and the lands filled for the purpose of re-settlement and constructions. This study explores a) to find the challenges of population growth on the availability of agricultural lands, b) to find the correlation between population growth and the loss of agricultural lands, and c) to provide strategies to manage the land use for the sustainable development. Both primary and secondary data were used in the study. For this purpose, by using GIS 10.5 software, land use map was created to delineate the contrasts between the agricultural areas and built up land. The finding of the study revealed that the rapid population growth in the coastal areas of Ampara District has negatively impacted on the availability of the agricultural land.

Agriculture is the mainstay of Pakistan’s economy. However, it has been noticed that farmers are increasingly giving up agriculture in favor of non-agricultural activities. This study was conducted in the Khairpur district of Sindh province, which is part of the Indus Plains in Pakistan. The main purpose of the study was to investigate the current and future land use change (LUC) trends and to study farmers’ perceptions of the causes and consequences of LUC and agricultural land abandonment (ALA) in the study area. The study used field survey data and secondary data obtained from the government sources. The results show that agricultural land in the region has decreased by about 9% in the past two decades. Survey data analysis confirms this because more than 80% of farmers believe that agricultural land in the area has declined over time. In addition, farmers believe that socioeconomic and environmental changes are the main reasons for LUC and ALA. We used a logistic regression model to determine the factors that influence farmers’ decisions to sell agricultural land for other uses. The results show that the age, income, land ownership, farm inheritance by successors, social networks and lack of basic facilities in the study area are the main determinants of farmers’ decisions to sell agricultural lands. In particular, farmers’ integration into the social network and their belief that the farm will be inherited by heirs reduces the possibility of selling land. As for the consequences of LUC and ALA, the results indicate that farmland prices, weeds infestation, urban diffusion, and pressure on existing infrastructure have increased in the study area. In addition, the results show that the prospects of farming in the area remain grim as most farmers indicated that they were willing to abandon agricultural lands in favor of other revenue generation activities. The study suggests that policymakers should pay close attention to controlling rapid LUC and ALA to keep lands green.

Abstract Background Urban areas are often built along large rivers and surrounded by agricultural land. This may lead to small tributary streams that have agricultural headwaters and urbanized lower reaches. Our study objectives assessed are as follows: (1) landscape, geomorphic, and water quality variables that best explained variation in aquatic communities and their integrity in a stream system following this agricultural-to-urban land use gradient; (2) ways this land use gradient caused aquatic communities to differ from what would be expected for an idealized natural stream or other longitudinal gradients; and (3) whether the impacts of this land use gradient on aquatic communities would grow larger in a downstream direction through the agricultural and urban developments. Our study area was an impaired coldwater stream in Michigan, USA. Results Many factors structured the biological communities along the agricultural-to-urban land use gradient. Instream woody debris had the strongest relationship with EPT (Ephemeroptera, Plecoptera, and Trichoptera) abundance and richness and were most common in the lower, urbanized watershed. Fine streambed substrate had the strongest relationship with Diptera taxa and surface air breather macroinvertebrates and was dominant in agricultural headwaters. Fish community assemblage was influenced largely by stream flow and temperature regimes, while poor fish community integrity in lower urban reaches could be impacted by geomorphology and episodic urban pollution events. Scraping macroinvertebrates were most abundant in deforested, first-order agricultural headwaters, while EPT macroinvertebrate richness was the highest downstream of agricultural areas within the urban zone that had extensive forest buffers. Conclusion Environmental variables and aquatic communities would often not conform with what we would expect from an idealized natural stream. EPT richness improved downstream of agricultural areas. This shows promise for the recovery of aquatic systems using well-planned management in watersheds with this agricultural-to-urban land use pattern. Small patches of forest can be the key to conserving aquatic biodiversity in urbanized landscapes. These findings are valuable to an international audience of researchers and water resource managers who study stream systems following this common agricultural-to-urban land use gradient, the ecological communities of which may not conform with what is generally known about land use impacts to streams.

The aim of the work was the landscape analysis of agricultural geographical landscapes in the Altai Territory and elaboration of measures aimed at the rational use of agricultural lands. Environmental and landscape (landscape) approach became the main method of scientific research used in the analysis of modern agricultural landscapes. The cartographic method, using GIS-technologies, made it possible to digitize the obtained materials. Synthesized maps of agro-ecological, natural and other zoning of territories are based on topographic, soil, geobotanical and other thematic maps made during land surveying during the field survey. Retrospective analysis, induction and deduction methods,analysis and synthesis, as well as the abstract-logic method were also used in the work. Our main result was the analysis of land use territory for agricultural enterprise in municipal district of Altai Krai. Exploration of lands indicates a pronounced plant-growing specialization of JSC “Pobeda” with a developed animal breeding direction. Limiting factors affecting the rational use of land are natural and climatic conditions, terrain,unsystematic anthropogenic activity and, as a result, the development of erosion processes. The degree of eroded and deflated arable land is more than 50%, hay and pasture lands are also very unstable. Landscapes have been typified, based on which eleven types of land have been identified and their geomorphological description has been carried out. The first five types of land can be used for agricultural production with limitations compensated by crop technology and erosion control measures, the sixth and seventh types require grassing and, in some cases,conservation, the eighth and ninth types can be partially used for pasture and area valorization; the remaining two are not suitable for agricultural use but should be potentially used for planting and forest management. As a result of the presented transformation of agricultural lands, the structure of cultivated areas has changed. The area of arable land decreased by 877 ha, and of pastures by 365 ha,while the area under hayfields, fallow lands, and forest lands increased by 295, 191, and 875 ha respectively. Low-productive lands were withdrawn from agriculture. We suggested that the sustainability of agricultural land use was mainly caused by the reduction of anthropogenic load and increase in ecological equilibrium of the territory.

Research Highlights: Forest conservation policies can drive land-use change to other land-use types. In multifunctional landscapes, forest conservation policies will therefore impact on other functions delivered by the landscape. Finding the best pattern of land use requires considering these interactions. Background and Objectives: Population growth continues to drive the development of land for urban purposes. Consequently, there is a loss of other land uses, such as agriculture and forested lands. Efforts to conserve one type of land use will drive more change onto other land uses. Absent effective collaboration among affected communities and relevant institutional agents, unexpected and undesirable land-use change may occur. Materials and Methods: A CLUE-S (Conversion of Land Use and its Effects at Small Scales) model was developed for the Deep Creek watershed, a small sub-basin in the Okanagan Valley of British Columbia, Canada. The valley is experiencing among the most rapid population growth of any region in Canada. Land uses were aggregated into one forested land-use type, one urban land-use type, and three agricultural types. Land-use change was simulated for combinations of two forest conservation policies. Changes are categorized by location, land type, and an existing agricultural land policy. Results: Forest conservation policies drive land conversion onto agricultural land and may increase the loss of low elevation forested land. Model results show where the greatest pressure for removing land from agriculture is likely to occur for each scenario. As an important corridor for species movement, the loss of low elevation forest land may have serious impacts on habitat connectivity. Conclusions: Forest conservation policies that do not account for feedbacks can have unintended consequences, such as increasing conversion pressures on other valued land uses. To avoid surprises, land-use planners and policy makers need to consider these interactions. Models such as CLUE-S can help identify these spatial impacts.

Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.

Sub-Saharan Africa (SSA) land use changes are primarily influenced by agriculture and its population. The region faces various challenges ranging from rainfall variabilities to poverty and insecurities, which further hampered food supply and production. The spatial analysis identified six land uses—agriculture, forest, grassland, wetland, urban, and others (i.e., bare land, water, and sparse vegetation), showing relative percentage changes. Additionally, information collected and analyzed shows that the Millennium Development Goals period witnessed increased agricultural land use changes in the environment to improve food supply, and farmers adopted local methods and native experiences to mitigate environmental particularities facing the region. Farmers’ landholdings are fragmented, and food supply per capita is low albeit rich in calories, and nutrition is still unbalanced, while bushmeat consumption is popular and serves as an alternative to animal-sourced protein. Concerted efforts should be made to improve food security and edge closer to the sustainable development goal during this decade.

This study focuses globally on the effects of desertification and drought on agricultural lands. Desertification, which shows more its effects from region to region all over the world and particularly on certain continents, contains factors that will disturb the human future. One of these negative factors is the risk of creating food vulnerability by directly damaging agricultural areas. The risk of desertification reducing the quality of human life and threatening other living plants and habitats is a very important issue that should be highlighted by the international system. In this context, the study draws attention to the negative impact of global desertification, as well as the reduction of agricultural and arable land and the risks of declining crop yields. Among other problems caused by desertification, the study emphasizes socio-economic instability due to migration and climate-related conflicts, world hunger and lack of grain and food. In the study, the literature on global desertification, drought and arable agricultural land was searched and selected source information from the literature is included in the study. In addition, the study was supported by maps, graphs, and tables, as well as desertification researches and analyzes. Due to the limitation of the pages, other factors, such as global warming triggering desertification, have not been addressed, and environmental issues, which are directly damaged by desertification other than arable agricultural areas, are excluded from the field of this study.

The paper studies the issue of the use of disposed agricultural land through the example of LLC “Alliance-agro in Sengileevsky district of the Ulyanovsk region. The authors consider the grounds for cultural and technical work and provide the results of a survey of unused arable land on the farm. A technology for the development of disposed agricultural land is proposed. Everyone knows that agricultural land is of particular importance as a means of agricultural production and is the second largest category of land in the unified land fund of the Russian Federation in terms of area, which includes the best and fertile lands making up the heritage of the country. Despite the fact that the schemes for the use of agricultural land are developed, many questions of a theoretical, methodological and applied nature need to be improved, since this is associated with incessant changes in the legal and organizational systems of land use. As a result of irrational use of land, degradation, littering, overgrowing with trees and shrubs of agricultural areas occurs. These processes lead to the fact that fertile lands are withdrawn from circulation. Our research is aimed to solve the problems in the field of the improvement of the cadastral registration of lands, the process of the organization of rational land use, as well as the most effective use of unused lands overgrown with trees and shrubs. The solution to this problem will help the rational transformation of the agricultural land use system and increase in their efficiency. Moreover it will help to solve the problem of the involvement of unused land in agricultural production and increase the efficiency of cadastral registration of agricultural land. As a result of the land clearing proposed by the authors, the sites of this object will be put into agricultural circulation, where any zoned agricultural crop can be grown from the first year of development in case of a favorable water-air regime in the root layer and complex agrochemical cultivation.
