Q1: What is the grey water footprint?
The grey water footprint is the relation between the amount of freshwater and its ability
to meet water quality standards. This is because freshwater is used to assimilate pollutants that
thus meet the specific standards (Water Footprint Network, n.d.).
Q2: What impact does virtual water trade have on global water use?
The impact virtual water trade has on global water use relies on the importer and exporter
factors, that influence the virtual water content, however, the challenges are that there are high
uncertainties in water-saving estimates and incorporating water pollution in water-saving
accounting. These come as important as the impact comes as if the exporter is less than the
importer there is regional water savings, and if the exporter is greater there is a loss in the
regional water savings towards the global water use (Virtual water trade, n.d.).
Q3: Climate change will produce changes in temperature and precipitation patterns. How will
this affect crop production?
Climate change is currently producing changes in the temperature and precipitation
patterns, in a distinguished matter of the threat of droughts along
California, and the Middle
East. With the interconnected measure, the effect of crop production is an international
component, in such the availability of water will become scarce. This is because crop production
is only useful through freshwater, and we are only seeing 3% on earth, and that is slowly
decreasing (TEDxTalks, 2016).
Q4: What agricultural technology was at the heart of the Green Revolution?
The agricultural technology that was labeled the heart of the green revolution was
identified in 1970 by the US agency for international development thanks to the work done by
Norman Borlaug, with the dramatic improvements in food production. This was first introduced
as a high-yielding semi-dwarf line for the Mexican breeding program, for solving the lodging
problem, this such allowed Mexico to become self-sustaining, and building this program to help
develop other countries like Pakistan and India, which were producing up to 20 million tonnes
(ndsubeancap, 2012).
Q5: How does the Aral Sea situation relate to the Water, Food, Energy nexus?
Water, Food, and Energy are all essential to human life and are interconnected, and with
one being the most basic element needed to grow crops and reproduce our energy, directly
impacts regions under distress, and that is what happened to the Aral Sea (CCTVNEWSbeijing,
2018). The Aral Sea was the fourth-largest lake, until massive irrigation in the 1960s diverted
water elsewhere, causing it to dry up, but northern parts are seeing light at the end of the tunnel
due to a large-scale restoration project (IIEA1, 2013).
