Rice water requirements: local assessment based on remote sensing data in the Lower Mondego (Portugal)

Autor: Isabel de Lima, João L. M. P. de Lima, Romeu G. Jorge

Irrigated rice agriculture, which is traditionally conducted applying continuous flooding, requires much more irrigation water than non-ponded crops. This can be a constraint in areas facing water scarcity issues, where the pursue for water resources

Estimating rice water requirements in the Lis Valley (Portugal) using remote sensing platforms: preliminary results for the 2020 cultivation season

Autor: João L. M. P. de Lima, Romeu G. Jorge, Isabel de Lima

In irrigated agricultural areas, where the availability of water for irrigation does not rely on any water storage, water management requires special attention, in particular under large annual and inter-annual variability in the hydrological regime

Autor: Isabel de Lima, Romeu G. Jorge, João L. M. P. de Lima

Publikováno v: Proceedings of the 1st International Conference on Water Energy Food and Sustainability (ICoWEFS 2021) ISBN: 9783030753146

Rice, which is strategic for food security in some countries, is traditionally grown under continuous flooding, thus requiring much more irrigation water than non-ponded crops. Fresh water shortage issues and steadily increasing competition for water

A contribution to the sustainable use of water in rice production in the Mediterranean region: the Lower Mondego case study (Portugal)

Autor: João L. M. P. de Lima, José P. L. de Almeida, Isabel de Lima, José Abreu, Romeu G. Jorge

The water use in agriculture has been the focus of special attention, particularly in regions where the pressure on water resources has increased and the prospect of climate change suggests that the temporal and spatial distribution of rainfall will
