Spatial distribution and uncertainties of nitrogen budgets for agriculture in the Tagus river basin in Portugal – Implications for effectiveness of mitigation measures

Peer-reviewed publication
Abril, 2019
Mônaco
Portugal

The present study describes a methodology to quantify the gross soil nitrogen balance (SNB) for agricultural land use in the Tagus Nitrate Vulnerable Zone (TVZ) between 1989 and 2016, including effects of implementation of the EC Nitrates Directive (ND, 91/676/EEC) since 2004. The study uses decadal information from National Agricultural Census at parish level and is supported by a Geographical Information System (GIS). The average SNB of the TVZ decreased significantly (p 

The effect of irrigation service delivery and training in agronomy on crop choice in Tajikistan

Peer-reviewed publication
Janeiro, 2019
Tajiquistão

The aim of this paper is to analyze the effect of irrigation delivery services and agricultural extension services on crop choice in southern Tajikistan. This analysis is motivated by the government’s recent efforts to address the country’s severe malnutrition problem by supporting changes in irrigation service delivery and agronomy to increase diversity in agricultural production and consumption, in an environment where the cultivation of cotton had, until recently, been mandatory.

Classification of farmland ownership fragmentation as a cause of land degradation: A review on typology, consequences, and remedies

Peer-reviewed publication
Outubro, 2016
Estados Unidos

Farmland ownership fragmentation is one of the important drivers of land-use changes. It is a process that in its extreme form can essentially limit land management sustainability. Based on a typology of land degradation and its causes, this process is here classified for the first time as an underlying cause which through tenure insecurity causes land degradation in five types (water erosion, wind erosion, soil compaction, reduction of organic matter, and nutrient depletion).

Green infrastructure planning: Unveiling meaningful spaces through Foursquare users’ preferences

Peer-reviewed publication
Setembro, 2020
Espanha
Estados Unidos

The design of efficient Green Infrastructure —GI— systems is a key issue to achieve sustainable development city planning goals in the twenty-first century. This study’s main contribution is the identification of potential GI elements to better align the environmental, social and economic perspectives in the GI design by including information about the use, activities, preferences and presence of people. To achieve this, user generated content from Location Based Social Network —LBSN— Foursquare is used as a complementary data source.

Barrier identification framework for the implementation of blue and green infrastructures

Peer-reviewed publication
Novembro, 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.

The local costs of biodiversity offsets: Comparing standards, policy and practice

Peer-reviewed publication
Agosto, 2018
Madagáscar

Biodiversity offsets seek to counterbalance loss of biodiversity due to major developments by generating equivalent biodiversity benefits elsewhere, resulting, at least in theory, in ‘no net loss’ (or even a ‘net positive gain’) in biodiversity. While local costs of major developments themselves receive significant attention, the local costs of associated biodiversity offsets have not.

Design of a decision support tool for visualising E. coli risk on agricultural land using a stakeholder-driven approach

Peer-reviewed publication
Junho, 2017
Global

Enabling knowledge exchange between scientists and decision-makers is becoming increasingly necessary to promote the development of effective decision-support tools (DSTs) for environmental management. Participation of stakeholders in the design process beyond a basic level of consultation is essential for promoting trust in modelled outputs and accelerating eventual uptake of resulting tools and models by end-user communities. This study outlines the development of a DST to visualise and communicate the spatial and temporal patterns of E.

Missed opportunity? Framing actions around co-benefits for carbon mitigation in Australian agriculture

Peer-reviewed publication

Austrália

França
Estados Unidos

Agriculture around the world is one of the industries most affected by, and faced with responsibility to mitigate, climate change. Through improvements in technology and efficiency as well as changes to land use management, agriculture can make an important contribution to meeting global commitments such as the Paris agreement or the Sustainable Development Goals. Yet international carbon markets have not resulted in sufficiently high financial returns to motivate the full potential of land sector changes in Australia and globally.

Local biophysical effects of land use and land cover change: towards an assessment tool for policy makers

Peer-reviewed publication
Janeiro, 2020
Noruega
Estados Unidos

Land use and land cover change (LULCC) affects the climate through both biogeochemical (BGC) and biophysical (BPH) mechanisms. While BGC effects are assessed at global scale and are at the heart of climate treaties such as the Paris Agreement, BPH effects are totally absent despite their increasingly recognized impact, especially at local scale. This stems from the complexity in characterizing their climate impacts both at local and global scale, which makes it impractical to offer clear advices for the development of climate policies.

Mapping hotspots and bundles of forest ecosystem services across the European Union

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.

Modelled impacts of policies and climate change on land use and water quality in Austria

Peer-reviewed publication
Junho, 2018
Áustria

Climate change is a major driver of land use with implications for the quality and quantity of water resources. We apply a novel integrated impact modelling framework (IIMF) to analyze climate change impacts until 2040 and stakeholder driven scenarios on water protection policies for sustainable management of land and water resources in Austria. The IIMF mainly consists of the sequentially linked bio-physical process model EPIC, the regional land use optimization model PASMA[grid], the quantitative precipitation/runoff TUWmodel, and the nutrient emission model MONERIS.
