World population, which is currently 6.5 billion, is growing at 76 million annually, with an expected peak at 9.5 billion by 2070.
For the first time, global population estimates this year show that more people live in cities than in rural areas. The Food and Agriculture Organization of the United Nations projects that almost all of the population growth between 2000-2030 will be urban.
By 2020, according to the International Resource Centre for Urban Agriculture and Forestry, some 75 percent of the world’s city dwellers will live in developing countries – many of them in poverty. Already in parts of sub-Saharan Africa, according to the UN, almost three-quarters of city residents live in rapidly growing slums. And this isn’t a migration of rural poor to the cities. These are groups impoverished by living conditions within the urban setting which prevents access to basic needs such as clean water, sewers, education and food production or the availability of fresh foods. 
This is a scenario which will become more common I feel in days and months ahead. And living in the United States does not mean we are exempt. Residents of inner cities and marginal income areas have suffered from a lack of access to quality fresh foods for decades. It’s just that more of us may become aware of this problem in the months ahead.
One answer to over-crowding in our cities and to the wasted space atop business building, schools, hospitals and yes, parking garages (while we still have them) is to create garden oases. And one of the quickest and most cost-effective ways to do that is with childrens’ wading pools. Back in the mid-1990’s, Dr. Job Ebenezer was then Director of Environmental Stewardship and Hunger Education for the Evangelical Lutheran Church in Chicago, Illinois. Dr. Job (as I refer to him) initiated an experiment in food growing on the rooftop of the church’s parking garage. Practical, compassionate, inventive and determined, Dr. Job is a true hero in service to hi
s community.
The hope was that the roof top garden would serve as a role model for creative use of urban space throughout the country. Dr. Job proved the feasibility of growing vegetables in plastic wading pools, used tires and feed sacks. Urban gardeners at the ELCA offices in Chicago harvested nearly 1,000 pounds of vegetables from approximately 40 wading pools and a dozen of used tires and feed sacks. Here are his figures from those years: (more…)
