<br />el <br /> <br />to increase the feasibility of irrigation and both "economic crisis" <br /> <br /> <br />and "energy crisis" may tend to decrease the feasibility of irriga- <br /> <br /> <br />tion. Any combination of futures is likely to create either no change, <br /> <br /> <br />or a decrease in feasibility unless a "food crisis" is present to <br /> <br /> <br />offset the effects of the energy or economic crisis. Therefore, <br /> <br /> <br />there appears to be little basis for projecting significant changes <br /> <br /> <br />in crop values, irrigation costs, or water availability in irriga- <br /> <br /> <br />tion planning. <br /> <br />Alternative futures affect the feasibility of municipal and <br /> <br /> <br />industrial water supply planning through imposed changes in popu- <br /> <br /> <br />lation growth, per capita consumption, and industrial use. "Con- <br /> <br /> <br />trolled growth" may result in decreases in all three variables <br /> <br /> <br />especially if a resource conservation ethic is part of the "con- <br /> <br /> <br />trolled growth" future. "Economic crisis", "energy crisis", and <br /> <br />"food crisis" would cause some instability, slight decreases or no <br /> <br /> <br />change in the planning variables. If "sustained growth" is included, <br /> <br /> <br />significant decreases in each of the planning variables can be <br /> <br /> <br />expected. <br /> <br />Alternative futures affect water quality planning by imposing <br /> <br /> <br />changes on population growth, per capita wastes, quality standards, <br /> <br />value of effluent for agriculture, and available funds. "Controlled <br /> <br /> <br />growth" should result in decreased population growth, per capita <br /> <br /> <br />wastes, and higher quality standards. "Economic crisis", "energy <br /> <br /> <br />crisis", and. "food crisis" may all cause a reduction in standards <br /> <br /> <br />and a decrease in available funds. The value of effluent for <br /> <br /> <br />irrigation would increase significantly in a food crisis. Therefore, <br /> <br /> <br />water quality planning should proceed with consideration for various <br /> <br /> <br />levels of quality standards and funding.
