Assessment of the Relationship between Land Use and Flood Risk Based on a Coupled Hydrological–Hydraulic Model: A Case Study of Zhaojue River Basin in Southwestern China

Peer-reviewed publication
December, 2021
China

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.

Obstacles to the Development of Integrated Land-Use Planning in Developing Countries: The Case of Paraguay

Peer-reviewed publication
December, 2021
Paraguay

Land-use planning identifies the best land-use options by considering environmental, economic, and social factors. Different theoretical land-use plan models can be found in the literature; however, few studies focus on its practical application and particular challenges in different contexts, especially in the Global South. We use expert surveys to explore the feasibility and relevance of integrated land-use planning and data acquisition in developing countries using Paraguay as an example.

Scale Effects and Regional Disparities of Land Use in Influencing PM2.5 Concentrations: A Case Study in the Zhengzhou Metropolitan Area, China

Peer-reviewed publication
December, 2021
Global

Land use has been demonstrated to have an important influence on PM2.5 concentrations; however, how the scale effects and regional disparities in land use influence PM2.5 concentrations remains unclear. This study investigated the scale differences in spatial variations in PM2.5 concentrations, in spatial associations between PM2.5 concentrations and land use, and explored the effects of the spatial heterogeneity and action scale of land use on PM2.5 concentrations. The main findings indicated greater intra-unit variation at small scales and greater inter-unit variation at large scales.

The Constellation of Plans: Toward a New Structure of Comprehensive Plans in US Cities

Peer-reviewed publication
December, 2021
Global

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.

Exploring the Potential of Soil Salinity Assessment through Remote Sensing and GIS: Case Study in the Coastal Rural Areas of Bangladesh

Peer-reviewed publication
December, 2021
Bangladesh

Soil salinity is a negative impact of climate change, and it is a significant problem for the coastal region of Bangladesh, which has been increasing in the last four decades. The issue of soil salinity substantially limits the agricultural crop production in coastal areas. Therefore, a soil salinity assessment is essential for proper land-use planning in agricultural crop production. This research was carried out to determine the soil salinity area with different salinity levels in Barguna Sadar Upazila (sub-district).

A Multi-Scenario Land Expansion Simulation Method from Ecosystem Services Perspective of Coastal Urban Agglomeration: A Case Study of GHM-GBA, China

Peer-reviewed publication
December, 2021
Hong Kong
Macao S.A.R

Balancing urban development and ecosystem conservation in the context of natural resource scarcity can provide scientific guidance for land use planning. We integrated research methods, such as ecosystem services (ES) assessment, coastal vulnerability assessment, multi-objective linear planning, and land use change simulation, to develop a new model framework for multi-scenario urban land expansion simulation based on ecosystem services.

Response of Ecosystem Service Value to Spatio-Temporal Pattern Evolution of Land Use in Typical Heavy Industry Cities: A Case Study of Taiyuan City, China

Peer-reviewed publication
December, 2021
Global

Ecosystem services value (ESV) has been one index of quantitative evaluation for the ecological livability of heavy industry cities in the new era, which is intimately relevant to patterns of spatio-temporal changes in land use. This study aims to reveal the response of ecosystem service value in heavy industrial cities to the spatial-temporal evolution structure of land use and to analyze the cold and hot spots and sensitivity. In this study, Taiyuan was taken as an example, and Landsat images were adopted as the basic data.

To What Extent Is Hydrologic Connectivity Taken into Account in Catchment Studies in the Lake Tana Basin, Ethiopia? A Review

Peer-reviewed publication
December, 2021
Ethiopia

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.

Land Suitability Analysis as a Tool for Evaluating Soil-Improving Cropping Systems

Peer-reviewed publication
December, 2021
Global

Agricultural land use planning is based on the capacity of the soil to support different types of crops and is a prerequisite for better use of cultivated land. Land Suitability Analysis (LSA) is used to measure the level of suitability of growing a specific crop in the area and can also be used to evaluate future scenarios as a means for sustainable agriculture.

Evaluating Sustainability of Tourism Projects in Rural Land Development Base on a Resilience Model

Peer-reviewed publication
December, 2021
Global

The underutilisation or overutilisation of various interdependent and interacting factors poses a challenge to sustainable development and requires the development of an appropriate methodology to evaluate the sustainability of tourism development projects in rural Land (TDPRL). However, most previous evaluations of TDPRL sustainability are macro-oriented and ignore the entire project life cycle.

Improving Hill Farming: From Maize Monocropping to Alternative Cropping Systems in the Thai Highlands

Peer-reviewed publication
December, 2021
Thailand

Lately, the Hill Pond Rice System (HPRS) is being promoted as a form of alternative farming systems in selected northern provinces of Thailand, in which the land conversion is designed to maximize rainwater harvesting in farmland consisting of forest trees, water reservoirs, paddy fields, and high-value crop cultivation to serve environmental and livelihood needs.

Land Preservation Uptakes in the Escarpments of North-Eastern Ethiopia: Drivers, Sustainability, and Constraints

Peer-reviewed publication
December, 2021
Ethiopia

Agricultural land is an indispensable resource for agrarian communities worldwide. There is a growing awareness that the world’s arable land supplies are limited and finite. For the last five decades, the Government of Ethiopia (GoE) and other development organisations have carried out land preservation uptakes intended to curb the effects of land degradation and improve agricultural productivity through various soil and water conservation practices (SWCPs). The study assessed the sustainability, drivers, and constraints of SWCPs in Dessie Zuria and Kutaber Woredas of South Wollo.
