The rapid growth of China’s economy since the reform in 1978 should be largely attributed to urbanization. Nonetheless, in terms of farmland productivity, urbanization may lead to perverse incentives and thus threaten food security.
The research presented in the paper intends to overcome an information gap on the evolution of urbanized surfaces in Italy which in the studies carried out so far have never been available. The only historical data on this form of land use date back to the 1950s, and were extracted from a national cartography created by the Military Geographic Institute.
Papua New Guinea is a country in Oceania that hosts unique rain forests and forest ecosystems which are crucial for sequestering atmospheric carbon, conserving biodiversity, supporting the livelihood of indigenous people, and underpinning the timber market of the country.
Worldwide urban spatial expansion has become a hot topic in recent decades. To develop effective urban growth containment strategies, it is important to understand the spatial patterns and driving forces of urban sprawl.
Ghana is urbanising rapidly, and over half of the country’s population have lived in urban areas since 2010.
In this study, a knowledge-based fuzzy classification method was used to classify possible soil-landforms in urban areas based on analysis of morphometric parameters (terrain attributes) derived from digital elevation models (DEMs).
Peri-urban agriculture (PUA) has been widely regarded as a sub-field of multifunctional agriculture for improving the sustainability of urban environments. However, urban sprawl has both negative and positive effects on peri-urban farming, and the research on this issue in Japan is insufficient.
The complexity of spatial use has an impact on poverty and the development of slum settlements towards a decrease in environmental quality.
In the face of ongoing habitat loss and fragmentation, maintaining an adequate level of landscape connectivity is needed to both encourage dispersal between habitat patches and to reduce the extinction risk of fragmented wildlife populations.
Informal settlements in areas that are already disaster prone are an increasing problem. Climate adaptation is also often used as an excuse fo evictions to redevelop sites in a more climate-proof manner in what is often referred to as ‘climate gentrification.
