Abstract

The WATERAGRI concept aims to introduce a new framework for the use of small water retention approaches for managing excess and shortage of water as well as better recovery of nutrients from agricultural catchments (Fig. 1) applying a multi-actor approach. The objectives are to
(i) evaluate in dialogue with farmers the links between agricultural land and soil-sediment-water management for improved handling of situations with water excess and shortage, maximization of crop production and improving water quality and nutrient uptake by crops (work area (WA) 1 to 4);
(ii) undertake both socio-economic and sustainability analyses of proposed measures (WA 1 and 5);
(iii) develop a cloud-based simulation and data assimilation system based on a physically-based terrestrial systems model, which is able to assimilate in situ and remotely sensed observations of hydrological and plant variables and meteorological data in near-real time, and which gives feedback to control engineering structures such as drains and dams for improved farm-scale water management and retention (WA 2 to 7);
(iv) identify, develop and test affordable and easy-to-implement technical and operational farm solutions such as controlled drainage, regulated deficit irrigation, subsurface irrigation, groundwater recharge, farm constructed wetlands, soil management and nutrient recovery options (WA 3 to 5);
(v) assess the proposed techniques for their potential regarding adaptation to climate change and their impact on ecosystem services for different biogeographic regions using case studies (WA 6); and
(vi) disseminate long-term benefits for the farm, the local community and ecosystem from the implementation of specified sustainable innovations (WA 8)
