Assessing Agricultural Systems Using Emergy Analysis: A Bibliometric Review
Marinheiro, Joana; Serra, João; Fonseca, Ana; Marques-dos-Santos, CláudiaSustainable intensification requires metrics that are able to capture both economic performance and the often-hidden environmental inputs that support agriculture. Emergy analysis (EmA) meets this need by converting all inputs—free environmental flows and purchased goods/services—into a common unit (solar emjoules, sej). We conducted a PRISMA-documented bibliometric review of EmA in agroecosystems (Web of Scien...
Nitrogen inputs by irrigation is a missing link in the agricultural nitrogen cy...
Serra, João; Marques-dos-Santos, Cláudia; Marinheiro, Joana; Aguilera, Eduardo; Lassaletta, Luis; Sanz-Cobeña, Alberto; Garnier, Josette; Billen, GillesIrrigation, one of the 28 agri-environmental indicators defined in the European Common Agricultural Policy, is often neglected in agricultural nitrogen (N) budgets, while it can be a considerable source of N in irrigated agriculture. The annual N input from irrigation water sources (NIrrig) to cropping systems was quantified for Europe for 2000–2010 at a resolution of 10 × 10 km, accounting for crop-specific gr...
