The zone between the soil surface and the groundwater, is a complicated system governed by highly non-linear processes and interactions. Flow processes can alternatively be described by means of physical-mathematical models. According to Bastiaansen et al. (2004), unsaturated-zone models can be used to simulate the timing of irrigations and irrigation depths, drain spacing and drain depth, and system behaviour and response. The models have increased our understanding of irrigation and drainage processes in the context of soil–plant–atmosphere systems.
The ENSEMBLES EU-funded proposal (Hewitt, 2005) is an important recent effort to improve the skill of seasonal forecasts and to make them available to stakeholders. The ENSEMBLES proposal uses the collective expertise of 66 institutes to produce a reliable quantitative risk assessment of long-term climate change and its impacts. Particular emphasis is given to probable future changes in climate extremes, including storminess, intense rainfall, prolonged drought, and potential climate ‘shocks’ such as failure of the Gulf Stream.
2005) showed that WOFOST simulations of winter wheat yields, based on the available seasonal forecasts, departed significantly from the recorded data. However, using spatial and temporal aggregated data, as usually done by JRC when providing recommendations to the EU Commission of Agriculture, might be not the right approach to capture the relationships between weather variables and crop growing. Hansen et al. (2006) provided an insight view of current advances and challenges while translating climate forecasts into reliable agricultural decision-making.
