Building an effective coalition to improve forest policy: Lessons from the coastal Tripa peat swamp rainforest, Sumatra, Indonesia

Peer-reviewed publication
Novembre, 2020
Indonésie

In recent history, Indonesian forest policies have been dominated by deforestation in the name of economic progress. Many actors have expressed concerns about this trend and have tried to reverse it in favour of a more sustainable pathway. From 2004–2017, non-governmental environmental organisations fought for the case of the coastal Tripa peat swamp rainforest in the province of Aceh, Sumatra. Unique in Indonesian history, they managed halting and reversing the deforestation of an area.

Strategic use of land policy instruments for affordable housing – Coping with social challenges under scarce land conditions in Swiss cities

Peer-reviewed publication
Novembre, 2020
États-Unis d'Amérique

For decades, many cities have introduced densification policy objectives to stop urban sprawl or to promote efficient use of natural resources. In the urban housing sector, however, densification projects often intensify social challenges. Due to rising rents after modernization of existing housing stocks as a consequence of densification, low-income tenants are forced to leave their apartments. Risks of social exclusion and segregation increase simultaneously.

Land tenure security for women: A conceptual framework

Peer-reviewed publication
Novembre, 2020
Norvège

While strengthening women’s land rights is increasingly on national and international agendas, there is little consensus on how to understand women’s tenure security. Analyses of women’s land rights often use very different definitions of land rights, from formal ownership to women’s management of plots allocated to them by their husbands. This paper identifies aspects of women’s tenure that should be included in indicators. It then provides a conceptual framework to identify the various dimensions of women’s land tenure security and the myriad factors that may influence it.

Forests cover about 40 % of the European Union (EU), providing a wide spectrum of invaluable ecosystem services to more than half a billion people. In order to protect and harness this crucial asset, EU policies are advancing multifunctional management. This study lays a basis for such an effort by mapping the supply of key forest ecosystem services (FES) across the entire EU: wood, water supply, erosion control, pollination, habitat protection, soil formation, climate regulation and recreation.

Barrier identification framework for the implementation of blue and green infrastructures

Peer-reviewed publication
Novembre, 2020
Global

Blue-green infrastructure (BGI) is becoming a more popular means of dealing with climate change and climate change-related events. However, as the concept of BGI is relatively new, many urban and rural planners are unfamiliar with the barriers they may face during the lifecycle of a BGI project. As a result, some have been hesitant to adopt BGI solutions. The literature has unveiled many of the barriers that inhibit the successful development of BGI, however, this information has yet to be presented in a manner that allows for easy identification.

Measuring environmental incomes beyond standard national and ecosystem accounting frameworks: testing and comparing the agroforestry Accounting System in a holm oak dehesa case study in Andalusia-Spain

Peer-reviewed publication
Novembre, 2020
Global

The standard System of National Accounts (SNA) omits the costs of the environmental inputs from nature and the environmental fixed asset degradation from the national/sub-national natural working landscapes. The United Nations Statistic Division (UNSD) is currently drafting the standardization of the Experimental Ecosystem Accounting (EEA), as part of the System of Environmental-Economic Accounting (SEEA).

Farm size and smallholders’ use of intercropping in Northwest China

Peer-reviewed publication
Novembre, 2020
China

Intercropping, i.e. the cultivation of crop species mixtures, can potentially reduce pressure on land resources by generating higher yields through exploitation of complementarities between crop species. Although intercropping is practiced on a non-negligible proportion of China’s arable land, little is known about the factors that influence farmers’ decisions to use intercropping. In this study we develop a theoretical framework that distinguishes exogenous factors from endogenous factors in farmers’ activity choices in general and the use of intercropping in particular.

Cost-Benefit Analysis of Landscape Restoration: A Stocktake

Peer-reviewed publication
Octobre, 2020
Global

With the increase in demand for landscape restoration and the limited resources available, there is need for economic analysis of landscape restoration to help prioritize investment of the resources. Cost-benefit analysis (CBA) is a commonly applied tool in the economic analysis of landscape restoration, yet its application seems limited and varied. We undertake a review of CBA applications to understand the breadth, depth, and gaps. Of the 2056 studies identified in literature search, only 31 met our predefined criteria.

Developing a UML Model for the 3D Cadastre in Poland

Peer-reviewed publication
Octobre, 2020
Poland

The UML model of a land and building cadastre is defined in current Polish legal regulations. Its main part is the UML application schema that defines relationships between the main cadastral objects in sixteen diagrams. These objects—cadastral parcels, buildings and (independent) premises—are essentially 2D objects. Their relationships with other cadastral objects are compared and analysed in this paper.

A Regression-Based Procedure for Markov Transition Probability Estimation in Land Change Modeling

Peer-reviewed publication
Octobre, 2020
Norway

Land change models commonly model the expected quantity of change as a Markov chain. Markov transition probabilities can be estimated by tabulating the relative frequency of change for all transitions between two dates. To estimate the appropriate transition probability matrix for any future date requires the determination of an annualized matrix through eigendecomposition followed by matrix powering. However, the technique yields multiple solutions, commonly with imaginary parts and negative transitions, and possibly with no non-negative real stochastic matrix solution.

Effect of Vegetation Removal on Soil Erosion and Bank Stability in Agricultural Drainage Ditches

Peer-reviewed publication
Octobre, 2020
Hungary
Germany

Maintenance of agricultural drainage ditches can be difficult to optimize if farmers have no guidelines on where to target their maintenance efforts. A main concern is whether ditch banks will experience soil erosion or mass movement (failure). In order to help identify sites that are more likely to experience soil erosion and/or mass movement, soil susceptibility to detachment was assessed in this study using a cohesive strength meter (CSM) and measurements of shear strength in unsaturated direct shear tests.
