Preprint
Greenhouse gas emissions embodied in international trade have risen sharply over the last few decades because of the globalization of economies and countries’ productive specialization. We have built a model able to trace all agro-food emissions along global value chains for 1986–2013. The results show that while the domestic fraction of food emiss...
Article
In this paper, we examine the evolution of Spanish agriculture from 1992 to 2017, exploring the specific relationship between the agricultural population and the provision of agroecosystem services (AE-S). Traditionally, family farming has sustained the quality of the biophysical fund elements of agroecosystems through the work that family members...
Article
Climate change mitigation depends to a large extent on economic sectors modifying their production processes to significantly reduce their greenhouse gas emissions, particularly CO₂. However, greenhouse gas emission assessments are usually excluded from management of capture fisheries. Traditionally, hake (Merluccius ssp.) has been an important foo...

Incorporation of crop residues can increase SOC stocks, but the extent of this depends on their C:N ratio and soil nutrient availability. Traditional wheat varieties (TWV) typically produce high straw biomass with high C:N ratio. We hypothesised that C:N ratio of straw of TWV are higher than those of modern (MWV) ones, resulting in lower carbon (C)...
Article
Mechanization of agriculture drastically increases labour productivity in crop production, playing a major role in industrialization by freeing up workforce for industry and services. These historical processes are well studied, but there is much less knowledge on their environmental implications, particularly the carbon footprint. In this work, we...
