Abstract Regionalization of food systems is a potential strategy to support environmental, economic and social sustainability. However, local preconditions need to be considered to assess the feasibility of such a transformation process. To better understand the potentials and perspectives of food self-sufficiency in urban and peri-urban areas, we determined the food self-sufficiency level (SSL) of a German metropolitan region, i.e., the percentage of the food demand that could be potentially provided on existing agricultural land. Main input parameters were actual food demand, agricultural productivity and its temporal variability and land availability. Furthermore, we considered changes in diet, food losses and land management. Based on current diets and agricultural productivity, the administrative region of Leipzig achieved a mean SSL of 94%, ranging from 77 to 116%. Additionally, an area of 26,932 ha, representing 12% of the regionally available agricultural land, was needed for commodities that are not cultivated regionally. Changes in food demand due to a diet shift to a more plant-based diet and reduced food losses would increase the SSL by 29 and 17%, respectively. A shift to organic agriculture would decrease the SSL by 34% due to lower crop yields compared with conventional production. However, a combination of organic agriculture with less food loss and a more plant-based diet would lead to a mean SSL of 95% (75–115%). Our results indicate the feasibility of food system regionalization in the study area under current and potential near future conditions. Addressing a combination of multiple dimensions, for example plant-based and healthier diets combined with reduced food loss and organic farming, is the most favorable approach to increase food self-sufficiency in urban and peri-urban areas and simultaneously provide synergies with social and environmental objectives.

Analysis of the carrying capacity of agricultural land is an analysis to determine the carrying capacityof land to the caloric needs of the population. Analysis of the carrying capacity of agricultural land canalso find out whether an area has or has not food self-sufficiency based on caloric needs of the population.The implication of this analysis is that it can find the optimal population that can be supported by existingagricultural land. From this analysis it can be seen that the area of crops and agricultural productivity aretwo factors that can increase the carrying capacity of agricultural land.

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.

The Impact

This paper investigates if the improvement of agricultural productivity will decrease rural to urban migration. Since rural to urban migration occurs due mainly to disparity between urban and agricultural wage, we assume that boosting agricultural income will reduce migration to urban areas. It is hypothesized that increase in agricultural productivity would result in a rise in agricultural wage, and hence income, ceteris paribus, reduces rural-urban migration. The data used in this study is the 2010 provincial statistics in West Java, Central Java, and East Java, Indonesia. The agricultural productivity and migration equations were estimated by using Ordinary Least Squares (OLS). The research findings may offer the suggestion to reduce rural to urban migration by boosting rural income through focusing the policy on agricultural productivity. Enhancing investment in agricultural sector such as increasing the number of subsidized fertilizer, adding agricultural labor and livestock, increasing education of rural people, and utilizing agricultural land resource are expected to increase agricultural output.Thus, it would also minimize the wage differential between urban and rural area.

Formed Part

Taxation of the agricultural sector is a major instrument for mobilization of the surplus to finance development projects within the agricultural sector and/or the rest of the economy. For many years, the need for a heavier taxation of agricultural land has formed part of the conventional wisdom regarding the ways of extracting agricultural surplus and increasing the tempo of agricultural development in poor countries. Land taxes have both equity and efficiency properties that gladden the hearts of both economists and vocal politicians belonging to urban areas. Taxes on land promote efficiency in the allocation of scarce resources by creating incentives for farmers to increase their effort and reduce their consumption, thus expanding the amount of agricultural produce available to the non-agricultural sectors of the economy. A tax on land has an important redistributive function because its incidence falls squarely on the landlord and is shifted neither forward to consumers nor backwards to suppliers of agricultural inputs; nor does it introduce distortions in the allocation of productive resources.

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.

Water scarcity has put pressure on city development in China. With a particular focus on urban and rural effects, logarithmic mean Divisia index decomposition (LMDI) was used to analyze the water footprint per capita (WFP) of food consumption in five East China cities (Beijing, Tianjin, Shanghai, Qingdao, and Xiamen) from 2008 to 2018. Results show that the WFP of food consumption exhibited an upward tendency among all cities during the research period. Food consumption structure contributed the most to the WFP growth, mainly due to urban and rural residents’ diet shift toward a livestock-rich style. Except in Beijing, the food consumption level mainly inhibited the WFP growth due to the decrease in food consumption level per capita in urban areas. Urbanization had less influence on WFP growth for two megacities (Beijing and Shanghai) due to the strictly controlled urban population inflow policy and more positive effects for other cities. The water footprint intensity effect among cities was mainly due to uneven water-saving efficiency. Meanwhile, Beijing and Tianjin have achieved advancement in water utilization efficiency.

The European Union (EU) has undergone significant economic crises in recent years. Therein, young people were amongst the hardest hit groups, with youth unemployment rising as high as 50% in some member states. Particularly high rates of youth unemployment were often observed in rural areas, where labour market supply in relation to demand were notably divergent. One of the core pillars of the EU’s agenda is to tackle the persistent problem of youth unemployment. Since the recent crisis, this has been via the “Youth on the Move” initiative, which involves the promotion of intra- and international mobility of young adults in order to gain access to job opportunities. However, what has received little attention so far is the question of what the general willingness of young adults to move is like, and to what extent this varies, for example, depending upon the area they live in. This paper therefore asks if rural youth differ from youth in urban areas in relation to their willingness to move for a job within their country or to another country. Moreover, what influences the general willingness to be mobile? Based on the Cultural Pathways to Economic Self-Sufficiency and Entrepreneurship (CUPESSE) Survey, which includes data on 18–35-year-olds in a sample of 11 European countries, it is shown that living in a rural area is strongly associated with the willingness to move. Furthermore, it shows that rural youth are more willing to move within the country but less willing to move to another country. Based on the presentation of the various factors, which promote or curb mobility readiness, the results make it clear that the success of EU initiatives depends on the preferences and willingness of the target group in question.

Urban Green Infrastructure

This study evaluates people’s preferences regarding the proximity of their residence to agricultural urban green infrastructure (UGI), such as agricultural land and satoyama, and discusses the availability of these types of land as UGI. UGI is vital for reducing the negative environmental impacts of urban areas, as these impacts are too large to ignore. In this study, we conducted an online survey and a choice experiment to investigate people’s perceptions regarding the proximity of their residence to agricultural UGI (AUGI). The respondents of the choice experiment were 802 inhabitants of Ishikawa Prefecture, Japan, which has rich agricultural resources. To examine explicitly the spatial autocorrelation of people’s preferences, in this study, we used the spatial econometrics method. The main empirical findings are that people prefer agricultural land far away from their residence—more than 1000 m, not within 1000 m—which reflects the not-in-my-backyard phenomenon. Meanwhile, people’s preferences regarding proximity to satoyama are complicated and their preferences are positively spatially autocorrelated. The results indicate that policymakers and urban planners should manage and provide AUGI far away from residential areas; otherwise, they must address people’s avoidance of neighboring AUGI.

The process of urbanization is taking place fast and vigorously in large urban and peri-urban areas in Vietnam. According to national forecasts, the rate of urbanization nationwide will reach 39.3% by 2020 and 50-55% by 2035. Thai Nguyen is a province in the midland and mountainous region. The province is located at the northern gateway and bordered with Hanoi capital. In recent years, the agricultural land area of Thai Nguyen province has narrowed due to the urban-industrial development. Urban agriculture development is an inevitable direction, creating safe and high quality food products, protecting the ecological environment, and increasing people's income. Thai Nguyen is one of the provinces promoting sustainable urban agricultural development. Secondary and primary data sources are analyzed and synthesized by descriptive statistical methods. The article will analyze five groups of factors affecting urban agricultural development in Thai Nguyen province in the period 2015-2018, including Socio-economic; Natural conditions and infrastructure; Policy factors; Planning factors; Links and integration.
