A number of severe ecological problems, and the altered structure of urban spaces, are ascribed to rapid urbanisation. Hence, an analytical framework for urban spatial structure and functional optimisation is highly beneficial to balance the contradiction between developing urban areas and protecting their ecosystems. In this paper, the proposed analytical framework included three parts. We first delineated the ecological suitability zones (ESZs) of Beijing City by applying the minimum cumulative resistance (MCR) model.
The Return of Wooded Landscapes in Wales: An Exploration of Possible Post-Brexit Futures
Changes in agricultural policy may have a rapid impact, even on landscapes which have taken millennia to form. Here we explore the potential impact of the UK leaving the EU as a catalyst for profound changes in the pastoral landscapes of Wales. Impending change of the trading regime governing agricultural produce, concurrent with public pressure to use agricultural subsidies for environmental goals, may lead to unforeseen consequences for the Welsh natural environment.
Restructuring the State: Policy Transition of Construction Land Supply in Urban and Rural China
Encountering the articulation of the strongness of local authorities and market forces in China’s development, attention has been paid to the changing central state which recentralised the regulation capability of localities which has more discretional power on resources utilisation, land for example, in the post-reform era. Yet it is still not clear-cut what drives the state rescaling in terms of land governance and by what ways. After dissecting the evolving policies and practices of construction land supply in China with the focus on the roles of state, we draw two main conclusions.
Spatial Variations of Vegetation Index from Remote Sensing Linked to Soil Colloidal Status
Recent decades have seen a progressive degradation of soils owing to an intensification of farming practices (weeding and high trafficking), increasing use of pesticides and fertilizers, mainly nitrogen, resulting in a steady decline in soil organic matter, a key component to maintain soil fertility. The work has coupled the normalized difference vegetation index (NDVI) of wheat cultivation in Central Italy to soil properties where the wheat was grown to identify the properties linked to within-field variability in productivity.
Characterization of Soil Carbon Stocks in the City of Johannesburg
Soil organic carbon (SOC) is a crucial indicator of soil health and soil productivity. The long-term implications of rapid urbanization on sustainability have, in recent years, raised concern. This study aimed to characterize the SOC stocks in the Johannesburg Granite Dome, a highly urbanized and contaminated area.
