Editor,While addressing the 2012 conference at Oxford University London last week, President Paul Kagame explained that it was time to globally re-think the optimal use of vital resources such as land, water and energy to ensure food security – for the rapidly growing population.The President was spot on.  It’s true that the question of food security is not about shortage per se, but rather other issues such as distribution, markets, management and use of potential and available resources.Resource management is the cornerstone of effective population control – and not turning our bodies into toxic wastelands.Margaret S.
