Spatio-Temporal Changes in Wildlife Habitat Quality in the Greater Serengeti Ecosystem

Peer-reviewed publication
Décembre, 2019
Global

Understanding habitat quality and its dynamics is imperative for maintaining healthy wildlife populations and ecosystems. We mapped and evaluated changes in habitat quality (1975–2015) in the Greater Serengeti Ecosystem of northern Tanzania using the Integrated Valuation of Environmental Services and Tradeoffs (InVEST) model. This is the first habitat quality assessment of its kind for this ecosystem. We characterized changes in habitat quality in the ecosystem and in a 30 kilometer buffer area.

Space-Time Analysis of Migrations, Employment, and Housing as A Basis for Municipal Sustainable Urban Planning

Peer-reviewed publication
Décembre, 2019
Global

A close relationship exists between population, the housing market and the level of employment at the local level. On the one hand, the housing market is influenced by local planning decisions and, on the other hand, that market is a significant factor in population and economic dynamization. Although there are studies on these variables, it is not common to include their spatial perspective by introducing Geographic Information System (GIS) tools in the analysis.

Bus Rapid Transit System: A Study of Sustainable Land-Use Transformation, Urban Density and Economic Impacts

Peer-reviewed publication
Décembre, 2019
Global

Bus Rapid Transit (BRT) has shown significant growth in recent years, particularly in developing countries because of its cost-effectiveness. However, empirical evidence on land-use and economic impacts of BRT is limited. This study measures the sustainable land-use transformation, urban density, and economic impact witnessed after the development of BRT. Spatial analysis shows that BRT has the potential to simulate land-use transformation, however, the extent of transformation is context-dependent. Population density has increased from 268 persons/acre to 299 persons/acre.

Probing Influence Factors of Implementation Patterns for Sustainable Land Consolidation: Insights from Seventeen Years of Practice in Jiangsu Province, China

Peer-reviewed publication
Décembre, 2019
China

Land consolidation is a key measure in the implementation of agricultural sustainability and has a strategic importance in farmland fragmentation reduction and rural revitalization. In order to understand spatiotemporal patterns of land consolidation implementation and their influences at a large scale, a comprehensive evaluation of 1046 land consolidation projects was conducted in Jiangsu Province, China.

Efficiency Impact of the Communal Land Distribution Program in Northern Ethiopia

Peer-reviewed publication
Décembre, 2019
Ethiopia

A rapid increase in population in sub-Saharan Africa has caused a decrease in farm size, an increase in the number of landless farmers, and soil erosion in communal forests due to increasing utilization. Ethiopia has addressed this problem by introducing an epoch-making privatization policy for the allocation of communal land to landless farmers. This policy promotes the economic utilization of the communal land while protecting natural resources. Hitherto, few studies have evaluated the impact of the policy.

Does Land-Use Policy Moderate Impacts of Climate Anomalies on LULC Change in Dry-Lands? An Empirical Enquiry into Drivers and Moderators of LULC Change in Southern Ethiopia

Peer-reviewed publication
Décembre, 2019
Global

The study set out to understand drivers of Land-Use Land Cover (LULC) changes in dry-land areas and investigate factors helping mitigate the adverse impacts of climate anomalies on LULC changes. By employing a mixed-methods design, it combined LULC data with socioeconomic and climatic data, to analyze the pattern of LULC changes and its socioeconomic and climatic driving forces along with moderating factors. It was found that rangeland decreased by 764 km2 (13% of total area) between 1986 and 2015.

Sustainable Land-Use Pathway Ranking and Selection

Peer-reviewed publication
Décembre, 2019
Global

The desire for refining status quo cost–benefit protocols to fully encompass econometric model uncertainty motivates the search for improved technology. Availability of unique Ethiopian highlands milk-market livestock data provides an ideal laboratory for investigation of alternative land-use pathway designs. In these contexts, we present novel methodology for ranking and selecting sustainable ‘land-use pathways,’ arguing that the methodology is central to sustainable-land-use-policy prescriptions, providing essential innovation to assessments hitherto devoid of probabilistic foundation.

Evaluation and Factor Analysis of the Intensive Use of Urban Land Based on Technical Efficiency Measurement—A Case Study of 38 Districts and Counties in Chongqing, China

Peer-reviewed publication
Décembre, 2019
China

Reasonable evaluation of the intensive urban land use has emerged as an important issue and hot topic for urban development. This paper aims to construct a unified framework for evaluating the intensive use of urban land and analyzing its influence channels. It combines the advantages of the approach of the indicator system and that of efficiency measurement, and provides an empirical test to apply this analytical framework using the panel data of 38 districts and counties in Chongqing, China, ranging from 2009 to 2018.

Reversing Uncontrolled and Unprofitable Urban Expansion in Africa through Special Economic Zones: An Evaluation of Ethiopian and Zambian Cases

Peer-reviewed publication
Décembre, 2019
Zambia
Ethiopia

Despite the growing attention on uncontrolled and unprofitable urban sprawling in many African countries, few pragmatic solutions have been raised or effectively implemented. While uncontrolled and unprofitable urban expansions happened primarily due to poor land use management and dysfunctional land market, the cost of land management enforcement and reform is high. This paper suggests that the recently re-emerging special economic zones (SEZs) in Africa could be a practical way of using government intervention to reduce uncontrolled urban expansion and optimize urban land use.

The Temporal Analysis of Regional Cultivated Land Productivity with GPP Based on 2000–2018 MODIS Data

Peer-reviewed publication
Décembre, 2019
China

The spatiotemporal change characteristics of Cultivated Land Productivity (CLP) are imperative for ensuring regional food security, especially given recent global warming, social development and population growth. Based on the hypothesis that the Gross Primary Productivity (GPP) is a proxy of land productivity, the Moderate Resolution Imaging Spectroradiometer (MODIS) data with 500-m spatial resolution and 8-day temporal resolution was employed by the Vegetation Photosynthesis Model (VPM) to calculate GPP in Jilin Province, China.

The Impact of Non-Agricultural Diversification on Financial Performance: Evidence from Family Farms in Italy

Peer-reviewed publication
Décembre, 2019
Italy

Diversification has been increasingly recognized as a rewarding farm strategy through which farmers produce on-farm non-agricultural goods and services. In doing so, farmers employ farm inputs (capital, labor, and land) in products other than agricultural goods, with the aim to sell them in the market and increase their income. While a significant body of literature has explored the drivers affecting the adoption of diversification activities, so far little attention has been given to the impact of such adoption on the technical and financial performance of farms.

Effectiveness of Polyacrylamide in Reducing Runoff and Soil Loss under Consecutive Rainfall Storms

Peer-reviewed publication
Décembre, 2019
Global

The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water. In this study, we determined the effective granular PAM rate that best reduces runoff and soil loss from Oxisols. Furthermore, the effectiveness of the selected PAM rate was tested by applying it in a mixture with gypsum (G) or lime (L).
