Applying Biodiversity Metrics as Surrogates to a Habitat Conservation Plan

Peer-reviewed publication
декабря, 2020
Global

Unabated urbanization has led to environmental degradation and subsequent biodiversity loss across the globe. As an outcome of unmitigated land use, multi-jurisdictional agencies have developed land use plans that attempt to protect threatened or endangered species across selected areas by which some trade-offs between harm to species and additional conservation approaches are allowed among the partnering organizations.

Empirical Modeling of Stream Nutrients for Countries without Robust Water Quality Monitoring Systems

Peer-reviewed publication
декабря, 2020
Global

Water quality models are useful tools to understand and mitigate eutrophication processes. However, gaining access to high-resolution data and fitting models to local conditions can interfere with their implementation. This paper analyzes whether it is possible to create a spatial model of nutrient water level at a local scale that is applicable in different geophysical and land-use conditions. The total nitrogen and phosphorus concentrations were modeled by integrating Geographical Information Systems, Remote Sensing, and Generalized Additive and Land-Use Changes Modeling.

An Integrated Economic, Environmental and Social Approach to Agricultural Land-Use Planning

Peer-reviewed publication
декабря, 2020
Australia

Agricultural land-use change is a dynamic process that varies as a function of social, economic and environmental factors spanning from the local to the global scale. The cumulative regional impacts of these factors on land use adoption decisions by farmers are neither well accounted for nor reflected in agricultural land use planning. We present an innovative spatially explicit agent-based modelling approach (Crop GIS-ABM) that accounts for factors involved in farmer decision making on new irrigation adoption to enable land-use predictions and exploration.

Forests to the Foreigners: Large-Scale Land Acquisitions in Gabon

Peer-reviewed publication
декабря, 2020
Gabon

For the past decade, the land rush discourse has analyzed foreign investment in land and agriculture around the world, with Africa being a continent of particular focus due to the scale of acquisitions that have taken place. Gabon, a largely forested state in Central Africa, has been neglected in the land rush conversations, despite having over half of its land allocated to forestry, agriculture, and mining concessions. This paper draws on existing evidence and contributes new empirical data through expert interviews to fill this critical knowledge gap.

Changes in Land-Use and Ecosystem Service Value in Guangdong Province, Southern China, from 1990 to 2018

Peer-reviewed publication
декабря, 2020
China

Land-use/cover is one of the major factors that affect the ecosystem and the services it provides. The impact of land-use change on ecosystem service value is a hotspot in developing countries, especially China—a region with rapid economic development and rapid population growth. As the leading area of China’s reform and opening-up, Guangdong province in southern China is subjected to land-use conversion that significantly alters the capacity of natural ecosystem to provide ecosystem services supporting human well-being.

Key Challenges for Land Use Planning and Its Environmental Assessments in the Abuja City-Region, Nigeria

Peer-reviewed publication
декабря, 2020
Global

Land use planning as strategic instruments to guide urban dynamics faces particular challenges in the Global South, including Sub-Saharan Africa, where urgent interventions are required to improve urban and environmental sustainability. This study investigated and identified key challenges of land use planning and its environmental assessments to improve the urban and environmental sustainability of city-regions.

A Comparison of Approaches to Regional Land-Use Capability Analysis for Agricultural Land-Planning

Peer-reviewed publication
декабря, 2020
Niger

Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought and increasing scarcity of arable land, more accurate land-use planning tools are needed to allocate land resources to support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements from 1305 field sites in the Dosso region of Niger. Based on these, we developed 250 m gridded maps of LCC values across the region.

The Benefits of Fit-for-Purpose Land Administration for Urban Community Resilience in a Time of Climate Change and COVID-19 Pandemic

Peer-reviewed publication
декабря, 2020
Global

The major global pressures of rapid urbanization and urban growth are being compounded by climate impacts, resulting in increased vulnerability for urban dwellers, with these vulnerabilities exacerbated during the COVID-19 pandemic. Much of this is concentrated in urban and peri-urban areas where urban development spreads into hazard-prone areas. Often, this development is dominated by poor-quality homes in informal settlements or slums with poor tenure security.

Assessing Matching Characteristics and Spatial Differences between Supply and Demand of Ecosystem Services: A Case Study in Hangzhou, China

Peer-reviewed publication
декабря, 2020
China

Ecosystem services (ESs) is a term used to describe the foundations of the well-being of human society, and several relevant studies have been carried out in this area. However, given the fact that the complex trade-offs/synergy relationships of ESs are a challenging area, studies on matching mechanisms for ES supply and demand are still rare.

Drivers of Land Use Conflicts in Infrastructural Mega Projects in Coastal Areas: A Case Study of Patimban Seaport, Indonesia

Peer-reviewed publication
декабря, 2020
Indonesia

Coastal areas are particularly sensitive because they are complex, and related land use conflicts are more intense than those in noncoastal areas. In addition to representing a unique encounter of natural and socioeconomic factors, coastal areas have become paradigms of progressive urbanisation and economic development. Our study of the infrastructural mega project of Patimban Seaport in Indonesia explores the factors driving land use changes and the subsequent land use conflicts emerging from large-scale land transformation in the course of seaport development and mega project governance.

Sources of and Control Measures for PTE Pollution in Soil at the Urban Fringe in Weinan, China

Peer-reviewed publication
декабря, 2020
China

The environment of the urban fringe is complex and frangible. With the acceleration of industrialization and urbanization, the urban fringe has become the primary space for urban expansion, and the intense human activities create a high risk of potentially toxic element (PTE) pollution in the soil. In this study, 138 surface soil samples were collected from a region undergoing rapid urbanization and construction—Weinan, China. Concentrations of As, Pb, Cr, Cu, and Ni (Inductively Coupled Plasma Mass Spectrometry, ICP-MS) and Hg (Atomic Fluorescence Spectrometry, AFS) were measured.
