salinity or by a combination of both salinity and sodium. Salinity Hazard Water with high salinity is toxic to plants and poses a salinity haz - ard. Soils with high levels of total salinity are call saline soils. High concentrations of salt in the soil can result in a “physiologi - cal” drought condition. That is, even though the field ...

dispersal, habitat preservation and soil fertility.17,18 While agroecological approaches strive to maximise synergies, trade-offs also occur in natural and human systems. For example, the allocation of resource use or access rights often involve trade-offs. To promote synergies within the wider food system, and best manage
