AgroHyd - Aims
The objective of the project is to increase productivity in agriculture by raising water-use efficiency on the basis of the following questions:
How can the water demand for food production be balanced according to the standard of the Life Cycle Assessment?
What measures raise water use efficiency substantially within plant production?
What measures raise water use efficiency substantially in livestock farming?
How high is the water demand of entire chains of production in agricultural food production?
To what extent will water demand for food production increase due to growing global population, climbing incomes, rising urbanization and the associated increase in shares of food production of animal provenance and other water-intensive food products?
What agricultural measures to increase water use efficiency are the most suitable for counteracting increasing exploitation of water resources for food production?
national and international
literature provides different
interpretation and use of the
term “water use efficiency”.
scientific disciplines use the
term interchangeably or
reciprocally as "water
our engineering dominated
understanding the water use
efficiency is the utilization
rate of a certain degree of
water use. A theoretical optimum
of 100 percent would be achieved
in the field of irrigation, if
the whole irrigation water was
used for the construction of the
plant dry matter.
