As an ecological consequence of intensified anthropogenic activities, more frequent extreme rainfalls have resulted in significant increases in water levels and discharge in southwestern China. This phenomenon presents a significant challenge in flood risk and ecological management. Land use is one of the major factors significantly affecting the flooding process, and it is inextricably tied to the ecological risk of floods. Hence, flood risk estimates based on land use are essential for flood control and land use planning.
The Constellation of Plans: Toward a New Structure of Comprehensive Plans in US Cities
The comprehensive plan is a fundamental planning document to direct growth and change in land use in US cities. This paper investigates whether US cities are structuring comprehensive plans to resemble a ‘constellation’ of functional, special topic, and neighborhood subplans tied to a central guiding plan. A traditional comprehensive plan features a central plan with few, if any, subplans. We analyzed the comprehensive plans of 39 cities and identified 20 cities that are using the constellation structure with at least four subplans.
To What Extent Is Hydrologic Connectivity Taken into Account in Catchment Studies in the Lake Tana Basin, Ethiopia? A Review
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.
Relationship between Land-Use Type and Daily Concentration and Variability of PM10 in Metropolitan Cities: Evidence from South Korea
Since urban areas with high air pollution are known to have higher mortality rates compared to areas with less air pollution, accurately understanding and predicting the distribution of particulate matter (PM) in cities is important for urban planning policies that seek to emphasize the health of citizens. Therefore, this study aims to investigate the relationship between PM and land use in metropolitan cities in South Korea using the land-use regression model. We use daily data from the air quality monitoring stations (AQMS) in seven cities in South Korea for the year 2018.
How Does Land Tenure Security Affect Farm Succession? Evidence from Apple Growers in China
The security of farmland property rights is an important factor that affects farmland investment and succession, and farm succession is highly significant for achieving sustainable agricultural development. In this study, based on survey data obtained from 1012 apple growers in Shandong and Shaanxi Provinces, we analyzed the impact of land tenure security on the farm succession willingness of farmers and related paths by constructing binary logistic regression and mediating effect models.
