The rise of population in urban areas makes it ever more important to promote urban agriculture (UA) that is efficient in terms of water and nutrients. How to meet the irrigation demand of UA is of particular concern in urban areas where water sources are often limited. [...]

Seagrass meadows store globally significant organic carbon (Corg) stocks which, if disturbed, can lead to CO2 emissions, contributing to climate change. Eutrophication and thermal stress continue to be a major cause of seagrass decline worldwide, but the associated CO2 emissions remain poorly understood. [...]

El fosfat és un nutrient imprescindible per a la producció primària, igual que els nitrats, tot i que sovint és menys abundant i més limitant. Però, com tot paràmetre, si supera unes concentracions determinades es converteix en un risc de contaminació pel medi natural. [...]
Phosphate, as nitrates, is an essential nutrient for primary production, although it is often less abundant and more limiting. However, like any parameter, if it exceeds certain concentrations, it becomes an environmental risk by causing eutrophication (excess of nutrients, mainly nitrogen and phosphorus). [...]

Organic farming is a key approach to reconcile food production, biodiversity conservation and environmental sustainability. Due to reduced inputs of agrochemicals, the success of organic farming is heavily dependent on the ecosystem services provided by the soil microbial community, and in particular by arbuscular mycorrhizal fungi (AMF).
