Agriculture plays a vital role in the socio-economic development of the world. For agricultural production, whether rainfed or using irrigation, water is a key requirement. Therefore, a thorough understanding of the hydrological processes in agricultural lands is essential to address a wide range of issues, including soil moisture condition, crop water requirement, agricultural productivity, water efficiency, soil erosion, and solute transport.
This Research Topic aims to address and advance our understanding of the role of hydrological processes in agricultural lands, including the modeling processes, impacts of climate change and human activities (e.g., irrigation, fertilization, mulching), the crop water productivity changes, cropping pattern changes, dynamics of water use efficiency, and the agro-ecosystem effects. The recent advances did not effectively link the field-based agricultural mechanism identification/detection and regional water-heat-carbon interactions/effects over the whole river basin.
Some of the topics and questions of interest are:
(1) Modeling the impacts of climate change on water balance and agricultural productivity at watershed scale;
(2) Identification of dominant hydrological factors and how they can be measured locally for improving water supply to crops;
(3) Effects of irrigation schemes on regional evapotranspiration and soil moisture content;
(4) Effects of artificial drainage on water regime and solute transport at different spatial scales;
(5) Aquifer vulnerability to high rates of fertilizer and pesticide applications;
(6) Multi-process and multi-scale water and energy transitions in agricultural lands;
(7) Water and energy responses of water-saving practice;
(8)Linking the hydrological issues with other environmental issues, including removal of natural vegetation, drought or flood events, and soil erosion.
