Managing salts while irrigating with wastewater por Qadir, Manzoor, Drechsel, Pay

“…Besides the off-farm interventions, on-farm management strategies may address (1) selection of crops or crop varieties capable of producing profitable yield with saline wastewater; (2) selection of irrigation methods reducing salt levels or crop exposure to salts; (3) application of wastewater in excess of crop water requirement to leach excess salts from the root zone; (4) irrigation of wastewater in conjunction with freshwater through cyclic and/or blending interventions; (5) use of different agronomic interventions; (6) the application - where possible - of calcium-supplying amendments while irrigating with highly sodic wastewater to mitigate sodium effects on soils and crops; and (7) potential use of saline wastewater, if containing adequate proportion of calcium, to ameliorate sodic and saline-sodic soils. …”

Urban agriculture por Gullers, Erik

“…The main drawbacks of food imports are contribution of greenhouse gas emissions. In contrast urban agriculture results in the following positive effects; • Shorter transports and decreased need of transports – as a result less emissions • Cities that are more energy efficient and therefore more sustainable • Money is spent locally which benefits the local economy • Gives employment The positive impacts urban agriculture has on a society is the main reason why the thesis is examining the economic factors influencing Swedish urban agriculture. …”
