E-raamat: Practical Applications of Agricultural System Models to Optimize the Use of Limited Water: Transdisciplinary Research, Synthesis, and Applications [Wiley Online]

The 15 papers in this collection propose crop system models to help optimize the use of water and nutrients, and explore adaptations and mitigations to climate change under a variety of conditions. The contributors simulate evapotranspiration and corn yield under growth-based irrigation schedules, circular planting in a dryland cropping system, the impact of cover crops on the water balance within olive orchards, and the amount of forage production available for livestock. Other topics include a mobile irrigation management app, a vineyard soil water model, determination of irrigation depths, and food security in India under climate change.

Completely devoted to applicati on of models to opti mize the use of limited water and nutrients in various climates, this collecti on will inspire confi dence in the capacity of modeling to tackle the biggest threats to secure agriculture. To obtain the most producti on from available water while maintaining natural resources, we need whole system–based quanti tati ve knowledge and tools to help select appropriate crops and manage water and associated inputs on a site-specifi c basis under changing climate. Site-specifi c experimental results are available for limited locati ons, limited periods of ti me, and limited management opti ons. Well-tested process models of cropping systems can extend fi eld research results to long-term weather conditi ons, as well as other climates and soils, allowing us to explore new management opti ons. The case studies in this volume are promising examples of these kinds of soluti ons.
