It is nearly three years now since my "Eureka" moment during my Nuffield when I contemplated water footprints. In my final presentation, I spoke about the fact that 80% of the UK's water footprint for the goods and food that it uses is outside our national boundaries i.e. we totally rely on water belonging to someone else for our food, our clothes, cars etc etc.
Is this a good thing for the UK? Are global supply chains becoming more brittle? Volanic ash has demonstrated that they can be vulnerable to risks that we do not control within those supply chains but those risks are assessed, managed and where possible mitigated on a daily basis by many organisations.
In the developing world water is seen as key natural capital that can be used to create products that can be sold to create cash income and develop lives and communities and that is the juxtaposition that we face. Switching natural capital into financial capital whether it is water or forest is good in the short to medium term for an economy but natural capital can take generations to replenish if it can be replenished at all and is the ultimate foundation of our survival.
Who does water belong to will be the mantra of the present and the future.
