With the tightening of resource and environmental constraints and the increasing manifestation of land use conflicts, construction land reduction has become an important way to optimize land resource allocation and improve resource use efficiency. Taking the towns of Zhuqiao and Zhujiajiao in Shanghai as research subjects, this paper uses field research and case studies to summarize the main practices and completion of the land reduction and analyzes the interest preferences of different stakeholders.

Access to land is crucial for food systems to address the challenges caused by habitat and biodiversity loss, land and water degradation, and greenhouse gas emissions. Sustainable food production requires land security upstream for agricultural production. Land security emanates from the land law implemented in-country by government policy. In the span of a decade (2007–2017), three different land reforms have been adopted in Benin.

Knowledge of hydrologic connectivity is important to grasp the hydrological response at a basin scale, particularly as changes in connectivity can have a negative effect on the environment. In the context of a changing climate, being able to predict how changes in connectivity will affect runoff and sediment transport is particularly relevant for land-use planning. Many studies on hydrology, geomorphology and climatology have been conducted in the Lake Tana Basin in Ethiopia, which is undergoing rapid development and significant environmental changes.
