摘要:In order to increase food production it is necessary to better understand all the factors underlying short term operations and long term strategies that lead to improve food security. In this regard any good effect deriving from agricultural research is strictly connected to a more accurate estimation of crops resources requirements, to major improvements in the use of irrigation and drainage systems, to a better understand of climatic variability. All the variables involved show strong dependency on both place and time. The failing of past, present and future systems can be essentially attributed to poor agricultural research planning, to incorrect agricultural systems design and resource allocation and to a not complete capacity to cope with short and long-term global climatic behavior.
