There was much discussion at the annual Women's Food and Farming Conference about whether the natural resources (capital) that we have will meet the demands of a growing population.
Water security is a key factor and the Independent reports that between Pakistan and India there is growing concern over water rights and water availability and how to tackle the current problems we have with rain fall versus demand. Farmers in Pakistan's food growing regions have accued India of reducing one of the subcontinent's most important rivers the Chenab to " little more than a trickle". The water table in the region has dropped from 50 feet below ground level to 100 feet. The lowering of the water table is an issue not only seen here but in many regions of the world. What do you do if your well doesn't reach the water?
