Regionalization of land use (LU) impact in life cycle assessment (LCA) has gained relevance in recent years. Most regionalized models are statistical, using highly aggregated spatial units and LU classes (e.g. one unique LU class for cropland). Process-based modelling is a powerful characterization tool but so far has never been applied globally fo...
Article
Agroforestry landscapes provide multiple benefits, including the capacity for storing carbon, thus contributing to climate change mitigation. In Portugal, the agroforestry system known as Montado (Dehesa in Spain) is heavily dependent on national and European financial incentives. Lack thereof, or insufficient level, often results in abandonment or...
Article
Full-text available
This research explains what happened to agricultural soil fertility during the "Campanha do Trigo" (Wheat Campaign) in Portugal, which began in 1929. It is commonly understood that the excessive expansion of wheat crops during the fascist "Estado Novo" (New State) regime led to the degradation of soils in the southern half of Portugal. This relatio...
Chapter
As Action 5 of the EU Biodiversity Strategy for 2020 called on EU member states to map and assess ecosystems and evaluate their services (MAES) in national territories, a pilot-project was created to set up a straightforward method for survey and evaluation of ecosystem types in the south of Portugal. The project’s primary aim was to produce ecosys...
Article
Sustainable food systems face trade-offs between demands of low environmental pressures per unit area and requirements of increasing production. Organic farming has lower yields than conventional agriculture and requires the introduction of nitrogen (N) fixing legumes in crop rotations. Here we perform an integrated assessment of the feasibility of...

Following the adoption of the GI strategy by the EU Commission, in 2013, a large number of green infrastructure (GI) initiatives have been planned and implemented in European city-regions. However, until recently, very few studies have integrated urban and periurban agriculture as part of a GI framework, and food system localisation objectives have...
Article
A good understanding of the sources of economic growth is fundamental. Total factor productivity (TFP) – frequently taken as synonymous of technical change but computed as a residual – is credited as a major driver of growth. Despite considerable efforts, the sources of TFP growth are still poorly understood. As all economic processes necessarily e...
Article
Full-text available
The Montado is an agro-silvo-pastoral ecosystem characteristic of the Mediterranean region. Pasture productivity and, consequently, the possibilities for intensifying livestock production depend on soil fertility. Soil organic matter (SOM) and phosphorus (P2O5) are two indicators of the evolution of soil fertility in this ecosystem. However, their...
Article
Livestock production is one of the main contributors to global greenhouse gas (GHG) emissions. The tools provided by the Intergovernmental Panel on Climate Change to estimate GHG emissions (Tier 1 and Tier 2) cannot be used as a tool for advising farmers or national policy on how to minimize GHG emissions because these estimates are not explicitly...
Article
Full-text available
Realistic predictions of climate change effects on natural resources are central to adaptation policies that try to reduce these impacts. However, most current forecasting approaches do not incorporate species-specific, process-based biological information, which limits their ability to inform actionable strategies. Mechanistic approaches, incorpor...
