Farm management adaptation options to climate change include changing sowing and harvest dates, changes in cultivars and irrigation, and selecting alternative crops . Irrigation is effective at reducing yield loss from heat stress and drought, for example, for wheat and maize , but it increases demand for water withdrawals . Where sufficient water and infrastructure is available, irrigation of wheat reverses yield losses across Europe at 2°C GWL to become gains, while yield losses in maize in SEU are reduced from as much as 80 to 11% . Extensive droughts during the past two decades have caused many irrigated systems in SEU to cease production  indicating limited adaptive capacity to heat and drought . Water management for food production on land is becoming increasingly complex due to the need to satisfy other social and environmental water demands  and is limited by costs and institutional coordination . Agricultural water management adaptation practices include irrigation, reallocating water to other crops, improving use efficiency and soil water conservation practices . In- season forecasts of climate impacts on yield were successfully used for European wheat during the 2018 drought .
