What makes decisions about urban water infrastructure forward looking? A fuzzy-set qualitative comparative analysis of investment decisions in 40 Dutch municipalities

Peer-reviewed publication
Fevereiro, 2019
Global

Municipalities worldwide are confronted with the need to take long-term decisions about ageing water infrastructure in the face of unpredictable future developments. Previous studies on long-term decision making have proposed solutions targeted at the domain of either politics or planning. This study combines insights from the domains of policy, politics, and planning by using the Multiple Streams Framework to explain what enables municipalities to take forward-looking investment decisions.

Alternative use of wheat land to implement a potential wheat holiday as wheat blast control: In search of feasible crops in Bangladesh

Peer-reviewed publication
Fevereiro, 2019
Bangladesh

The first occurrence of wheat blast in Bangladesh was confirmed in wheat (Triticum aestivum) fields in February 2016 and re-occurred in the subsequent years. This study explores the potential of alternative use of current wheat land as a strategy to combat the disease. Economically feasible alternative crops would need to be cultivated in the current wheat area by implementing a potential ‘wheat holiday’ – that is discontinuing wheat cultivation for a few years – be it in the 10 blast affected districts, in blast vulnerable districts or the entire country.

Effects of historical land use and land pattern changes on soil erosion – Case studies from Lower Austria and Central Bohemia

Peer-reviewed publication
Fevereiro, 2019
Áustria
República Checa
Estados Unidos

This paper addresses changes in land use and in the spatial distribution of land units and their influence on the soil erosion risk in two areas with a different geomorphology and a different historical and political development: an intensively-used lowland agricultural watershed in central Bohemia, Czech Republic, and a partially hilly agricultural and wine-producing municipality in northern Austria.

Application of land-use simulation to protected area selection for efficient avoidance of biodiversity loss in Canada’s western boreal region

Peer-reviewed publication
Fevereiro, 2019
Canadá

Avoided ecological loss is an appropriate measure of conservation effectiveness, but challenging to measure because it requires consideration of counterfactual conditions. Land-use simulation is a well suited but underutilized tool in this regard. As a case study for the application of land-use simulation to assess the impact of protected areas, we present a scenario analysis exploring conservation options in Canada’s western boreal forest.

Do farmers care about rented land? A multi-method study on land tenure and soil conservation

Peer-reviewed publication
Fevereiro, 2019
Áustria

Does ownership status of agricultural land determine farmers’ soil use behaviour? Why (not)? We investigate this old question using multiple methods and data. We apply econometric analysis to plot-level data to determine whether planting decisions differ between rented and owned plots. In addition, we analyse interviews with Austrian farmers with the aim of explaining (a lack of) differences. We find a very small influence of tenancy on crop choice in the quantitative part of the study, and qualify these findings in the qualitative part.

Key landscape features in the provision of ecosystem services: Insights for management

Peer-reviewed publication
Fevereiro, 2019
Canadá
Estados Unidos

Whereas ecosystem service research is increasingly being promoted in science and policy, the utilisation of ecosystem services knowledge remains largely underexplored for regional ecosystem management. To overcome the mere generation of knowledge and contribute to decision-making, scientists are facing the challenge of articulating specific implications of the ecosystem service approach for practical land use management.

How Community-Based Rangeland Management Achieves Positive Social Outcomes In Mongolia: A Moderated Mediation Analysis

Peer-reviewed publication
Fevereiro, 2019
Mongólia

Evidence-based policy guidance necessary for addressing mixed outcomes of community-based rangeland management (CBRM) is limited, dominated by case studies, and lacking coverage of diverse ecological settings. In remedy, we studied 65 traditional neighborhoods and 77 formally-organized CBRM groups across four ecological zones and investigated how and when CBRM obtains greater social outcomes than non-CBRM neighborhoods.

Analysis of High Temporal Resolution Land Use/Land Cover Trajectories

Peer-reviewed publication
Fevereiro, 2019
Global

In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequences, the entropy and the turbulence of the land trajectories, and the average time of permanence were computed. Clusters of similar sequences were determined using different dissimilarity measures.

Predicting Land Use Changes in Philadelphia Following Green Infrastructure Policies

Peer-reviewed publication
Fevereiro, 2019
Estados Unidos

Urbanization is a rapid global trend, leading to consequences such as urban heat islands and local flooding. Imminent climate change is predicted to intensify these consequences, forcing cities to rethink common infrastructure practices. One popular method of adaptation is green infrastructure implementation, which has been found to reduce local temperatures and alleviate excess runoff when installed effectively. As cities continue to change and adapt, land use/landcover modeling becomes an important tool for city officials in planning future land usage.

A Citizen-Contributed GIS Approach for Evaluating the Impacts of Land Use on Hurricane-Harvey-Induced Flooding in Houston Area

Peer-reviewed publication
Fevereiro, 2019
Global

Hurricane Harvey (2017) caused widespread flash flooding by extremely heavy rainfall and resulted in tremendous damage, including 82 fatalities and huge economic loss in the Houston, Texas area. To reduce hazards, loss, and to improve urban resilience, it is important to understand the factors that influence the occurrence of flooding events. People rely on natural resources and different land uses to reduce the severity of flood impacts and mitigate the risk. In this study, we focused the impacts of land use on Hurricane-Harvey-induced flooding inside and outside the Houston city center.

Agroforestry Systems of the Tehuacán-Cuicatlán Valley: Land Use for Biocultural Diversity Conservation

Peer-reviewed publication

México
América do Norte

The Tehuacán-Cuicatlán Valley, Mexico, is the semiarid region with the richest biodiversity of North America and was recently recognized as a UNESCO’s World Heritage site. Original agricultural practices remain to this day in agroforestry systems (AFS), which are expressions of high biocultural diversity. However, local people and researchers perceive a progressive decline both in natural ecosystems and AFS.
