Urbanization is an effect of population growth. Increasing population contributed to the expanding of urban areas as cities try to accommodate more people within a minimal landscape. Urbanization takes up valuable land, sometimes productive agricultural land that feeds the population. The objectives of this paper are to investigate the connection between urban sprawl and its impact on agricultural productivity, and ultimately whether it affects food security in Malaysia. For this qualitative exploratory review exercise, a Systematic Literature Review (SLR) of secondary data was employed as the base for this study. Data mining techniques were used to gather relevant literature that included archival data, academic writings, and publications. The data are then dissected, analysed, and clustered using Atlas ti 8 software, focusing on thematic analysis. Urbanisation did affect the self-sufficiency level (SSL) of Malaysian food security, especially on landintensive food products such as vegetables and livestock. Recent government initiatives such as urban farming, land use policies were promoted to reduce the differences in food imports, ensuring Malaysian food security to be at an acceptable level. Significant development of this population dense proximity has created urban sprawl beyond the city limits, taking up valuable land space. Land-use conversion from agricultural land in Malaysia has been studied regarding its adverse effects on agricultural production. Urbanization therefore does affect food security through the land conversion of agricultural lands.

In certain cases, the conversion of paddy fields is unavoidable. Nevertheless, the change in land use must consider various aspects of the feasibility of development, both legal aspects, physical aspects of the area, the environment and others.The objectives are to, analyze the implementation of the policy on the transfer of agricultural land into residential areas, and analyze the factors that support and hinder the implementation of the policy. The type of research used is descriptive qualitative, using primary and secondary data. Data collection methods are interviews, in-depth (Indep interview) and direct discussion or Focus Group Discussion (FGD), observation and literature review. The results of the study indicate that the activity of land conversion into a residential area in West Lombok Regency has been guided by the Regional Regulation and Regional Spatial Planning (RSP) No. 11 / 2011. The use of agricultural land for residential areas has been regulated in the determination of the spatial pattern of residential areas in urban areas. and rural areas, the inhibiting factor in implementing the land use change policy is the absence of a detailed regional spatial planning plan and the limited number of field officers. The supporting factors are the Regional Spatial Planning Coordination Team, which is coordinated by the Regional Secretary. The recommendation given is to immediately issue a Detailed Spatial Plan so that there is an even distribution of housing areas. It is necessary to make a regional regulation that specifically examines and regulates the conversion of land functions.

Land use change is contributing to the emergence of zoonotic diseases in the community. And can cause an increase in the spread of the virus through arthropods. This study aimed to determine the association of land use factors and dengue hemorrhagic fever in Kolaka District, Southeast Sulawesi Province, Indonesia. The secondary data obtained from various governments of Indonesia were used for this study. Data of dengue hemorrhagic fever from Ministry of Health of Republic Indonesia. Land use data is derived from the classification of Citra Landsat 8 on a scale of 1: 250,000 from 2010 to 2020. The Spearman rank correlation test was used to examine the relationship between land-use change and the incidence rate of dengue hemorrhagic fever. The results of this study In Period 2010-2015 is a correlation between Agriculture with dengue hemorrhagic fever ( α = 0.812, p <0.05), and water bodies with α =0.812. The area of agricultural land is increasing every year; in 2010, only 3.32% increase to 51.08% in 2015. Furthermore, in period 2016-2020 is a correlation between Forest with dengue hemorrhagic fever (α = 0.900, p <0.05), and Settlement (α = -0.900, p <0.05). Our findings could be used to improve the understanding of land-use change and dengue hemorrhagic fever in the Kolaka district and provide information on land use that does not damage the environment.

During the last decades, pastoralist, and agropastoralist populations of the world’s drylands have become exceedingly vulnerable to regional and global changes. Specifically, exacerbated stressors imposed on these populations have adversely affected their food security status, causing humanitarian emergencies and catastrophes. Of these stressors, climate variability and change, land-use and management practices, and dynamics of human demography are of a special importance. These factors affect all four pillars of food security, namely, food availability, access to food, food utilization, and food stability. The objective of this study was to critically review relevant literature to assess the complex web of interrelations and feedbacks that affect these factors. The increasing pressures on the world’s drylands necessitate a comprehensive analysis to advise policy makers regarding the complexity and linkages among factors, and to improve global action. The acquired insights may be the basis for alleviating food insecurity of vulnerable dryland populations.

Urban expansion is a dynamic and complex phenomenon, often involving adverse changes in land use and land cover (LULC). This paper uses satellite imagery from Landsat-5 TM, Landsat-8 OLI, Sentinel-2 MSI, and GIS technology to analyse LULC changes in 2000, 2005, 2010, 2015, and 2020. The research was carried out in Opole, the capital of the Opole Agglomeration (south-western Poland). Maps produced from supervised spectral classification of remote sensing data revealed that in 20 years, built-up areas have increased about 40%, mainly at the expense of agricultural land. Detection of changes in the spatial pattern of LULC showed that the highest average rate of increase in built-up areas occurred in the zone 3–6 km (11.7%) and above 6 km (10.4%) from the centre of Opole. The analysis of the increase of built-up land in relation to the decreasing population (SDG 11.3.1) has confirmed the ongoing process of demographic suburbanisation. The paper shows that satellite imagery and GIS can be a valuable tool for local authorities and planners to monitor the scale of urbanisation processes for the purpose of adapting space management procedures to the changing environment.

The intensified use of cultivated land is essential for optimizing crop planting practices and protecting food security. This study employed a telecoupling framework to evaluate the cultivated land use intensification rates in typical Chinese villages (village cultivated land use intensifications—VCLUIs). The pressure–state–response (PSR) model organizes the VCLUI indexes including the intensity press, output state, and structural response of cultivated land use. Empirical analysis conducted in Baiquan County, China, indicating that the cultivated land use intensification levels of the whole county were low. However, the intensifications of villages influenced by physical and geographic locations and socioeconomic development levels varied significantly. This paper also found that variations in the VCLUIs were mainly dependent on new labor-driven social subsystem differences. Thus, the expanding per capita farmland scales and increasing numbers of new agricultural business entities were critical in improving the VCLUI. Overall, the theoretical framework proposed in this study was demonstrated to be effective in analyzing interactions among the natural, social, and economic subsystems of the VCLUI. The findings obtained in this study potentially have important implications for future regional food security, natural stability, and agricultural land use sustainability.

Worldwide urban areas are having increasing influence over the surrounding landscape. Peri-urban regions of the world are facing challenges which results from sprawl with increasing problems of social segregation, wasted land and greater distance to work. This study seeks to examine the trends in land use dynamics, urban sprawl and associated development implications in the Bamenda Municipalities from 1996 to 2018. The study made use of the survey, historical and correlational research designs. The purposive and snowball techniques were used to collect data. Spatiotemporal analyses were carried out on Landsat Images for 1996, 2008, and 2018 obtained from Earth Explorer, Erdas Image 2014 and changes detected from the maps digitized. The SPSS version 21 and MS Excel 2016 were used to analyze quantitative and qualitative data. The former employed the Pearson correlation analysis. Analysis of land use/land cover change detection reveals that built-up area has increased significantly from 1996 to 2018 at the detriment of forest, wetland and agricultural land at different rates within each municipality. These changes have led to invasion of risk zones, high land values, uncoordinated, uncontrolled and unplanned urban growth. The study suggests that proactive planning, use of GIS to monitor land use activities, effective implementation of existing town planning norms and building regulations, are invaluable strategies to sustainably manage urban growth in Bamenda.

Rapid Pace

With the rapid pace of urbanization, land-use change is essential for economic and social progress; however, it does not come without costs. With such rapid urbanization, there comes pressure on the land and its resources, like that of food and timber production with a significant impact on the livelihood of millions of people. With the loss of agricultural land due to developmental activities, future agriculture would be very intensive. Therefore, it is likely with the existing pattern of allocating land uses for future development that we may lose the ecosystem services and highly productive agricultural lands. The value of these ecosystem services to agriculture is enormous and often underappreciated. The study focuses on identifying underlying causes of the land-use change, ecosystem services affected due to land-use change in peri-urban areas of Chandigarh using spatial mapping of affected ecosystem services and suggesting proposals for promoting agricultural ecosystem values using economically-informed policy instruments.
