“…This type of urban sprawl brings the most harmful to ecology [Anjarsariningtyas et al, 2016;Dupras et al, 2016] because it disrupts vegetation coverage that functions as the lungs of the outskirts and maintains the stability of microclimate. Furthermore, it also causes immediate negative impacts on agricultural activities due to the encroachment of productive and technically irrigated agricultural lands [Harini et al, 2014;Sriartha and Giyarsih, 2015;Sudrajat, 2016].…”

This research was conducted in the surrounding areas of a university, Universitas Muhammadiyah Yogyakarta (UMY), which is administratively located in Tamantiro Village, Kasihan District, Bantul Regency, the Special Region of Yogyakarta, Indonesia. It aims to formulate the regional management of the surrounding areas as they have been presenting the indications of urban sprawl. It used a qualitative method with research data obtained from in-depth interviews to 22 informants including governmental agencies (7 informants), academics (6 informants), entrepreneurs (5 informants), and villagers (4 informants). The informants were sampled using purposive sampling method. Data processing and analysis were conducted using qualitative descriptive method, i.e. (1) data reduction, (2) data presentation, and (3) data conclusion. Data validation and reliability tests were conducted using source triangulation method. The results show that the stakeholders proposed various management strategies to improve the positive impacts and, at the same time, reduce the negative impacts of urban sprawl. These management strategies include (1) consistency in implementing spatial planning regulation, (2) spatial synergism in development planning, implementation, and monitoring, (3) assistance to the native people and the migrants, and (4) integration between the university and the village.

“…Il peut être utile de tirer des leçons des expériences d'autres pays pour éviter de répéter les erreurs, notamment en réduisant le financement du développement urbain non durable. Pour lutter contre les effets du changement climatique sur les villes, les urbanistes et les habitants de la ville de Montréal travaillent désormais à mieux relier entre eux les espaces naturels de la ville (6,10). Cela pourrait contribuer à réduire l'effet d'îlot thermique urbain et à maintenir la densité des espèces vectrices et hôtes dans des limites raisonnables grâce à l'équilibre dynamique qui se crée dans les communautés écologiques (c'est-à-dire que les relations prédateur-proie des réseaux alimentaires se feraient dans tout un réseau d'espaces naturels plutôt que dans des zones isolées).…”

“…This also showed the conflicts of land use allocation in the urban-rural system. Studies on urban expansion have received increasing attention on consequential issues such as population growth, land scarcity and environmental pollution [53,54]. Land use competition has been much more intensely reflected in aspects of food production, urban-rural settlement and infrastructure construction [55].…”

Rapid urbanization in China has increased the demand of land resources for urban areas and caused a series of environmental problems. Ecological security under the pressure of urban sprawl has become one typical indicator for illustrating regional environmental conditions and thus inform urban development. As an important farming area and one of the core economic development regions in northeast China, Changchun City is now confronted with severe contradictions between economic growth, habitat conservation and food security. Therefore, with the aim of developing an approach to optimize a regional ecological security pattern and land use structure, this study built a comprehensive ecological security pattern taking into account regional ecological processes including water regulation, soil and water conservation, species protection and recreation. Three patterns of ecological security were identified responding to different levels of ecological conservation: the basic security pattern, the buffer security pattern and the optimal security pattern. Based on the constraint of the ecological security pattern, the preservation area of prime farmland was added to an urban expansion suitability pattern as an additional constraint to simulate scenarios of urban expansion. The results indicate that the basic security pattern covers an area of 374.23 km 2 , accounting for 19.27% of the total area of Changchun City. This pattern is considered as the ecological baseline that maintains the basic ecological functions, and it is the area where ecological land cannot be occupied for construction purposes. Furthermore, co-constrained by the preservation area of prime farmland, the ecological conservation area, the ecological restriction area and the suitable development area are 190.34 km 2 , 384.75 km 2 and 152.83 km 2 , respectively, accounting for 9.80%, 19.80% and 7.87% of the total area. It can be concluded that the suitable expansion area for the city is relatively limited when the conservation of farmland and regional ecological environment is considered. Therefore, positive actions such as industrial structure transformation and land use efficiency improvements should be perceived as a preferable pathway for urban development to balance economic growth, and regional ecological and food security.
