Given the increasing need for residential and economic development and also for the improvement of the living environment, for food and energy production, we should reflect on the use of agricultural lands. Even if the citizens and the regional government are rediscovering the multiple services provided by agricultural lands, we observe that the agricultural landscape in Wallonia (the southern part of Belgium) is in a precarious situation, especially at the edge of the cities.

Despite the efforts of developed countries to protect undeveloped land, development continues to expand beyond urban boundaries. High-quality land needed for food production is often consumed. This study aims to verify possible causes of undeveloped land and high-quality land consumption within regions (NUTS3) using a new approach to building growth monitoring. It investigates residential (RBs) and commercial buildings (retail and industrial buildings, RIBs). The development between 2006 and 2016 in the Czech Republic, a country in Central Europe, is used as a case study.

Urban agriculture is an important neighborhood revitalization strategy in the U.S. Rust Belt, where deindustrialization has left blighted and vacant land in the urban core. Immigrants and refugees represent a growing and important stakeholder group in urban agriculture, including in community gardens across the Rust Belt Midwest. Community gardens provide a host of social and economic benefits to urban landscapes, including increased access to culturally appropriate food and medicinal plants for refugee and immigrant growers.
