The problem is inefficiency of land use.  The extinction of species due to habitat loss necessitates the creation of an effective system of protected areas, including restoration of degraded land.  Land currently used for agriculture is at the pressure of development meaning less land to produce food on.  Land in urban areas is underutilized being generally used only for aesthetic purposes and often requiring large inputs of water and toxic chemicals such as fertilizer and pesticides.  If this land were to be used for agriculture there would be a multitude of benefits.  Furthermore, if a permaculture system and a well designed business model were in place more benefits would occur.

Urban lands, including residential yards, business properties, federal, state county and city owned landscapes could be converted to an organic permaculture system of food production with a CSA business model.  A landscape company skilled in the art of permaculture, with considerations not only for optimizing food production with the lowest use of inputs but also creating a beautiful aesthetic, would charge a standard fee for putting in the landscape.  They would also be paid by the homeowner to maintain the landscape.  A CSA would be in charge of harvesting the crop.  The homeowner would get a share of the CSA's sales from their property's harvest.  The share would be based on a percentage of the harvest.  It would be adjusted with a small percentage in the beginning and then plateauing at a larger rate in the course of several years.  In order to encourage the growth of skilled Permaculture landscape companies the government could give a subsidy to homeowners for putting in the system.  This would create a higher demand and thus more businesses.  The subsidy would only be for a few years, giving Permaculture Landscape Companies time to payback there initial investments and, also prevent inflation of the market, and lastly.

A side benefit to the system would be a reduction in the carbon footprint of agriculture.  Because food would be grown within communities the transportation length would be much less than the miles conventional food travels (an average of 1600 miles).   To cut back on transportation costs and carbon emissions the CSA would create areas for production and distribution.  This would depend on the concentration of "farms" and consumers.  Ideally, transportation would be less than three miles.  Given the production size
