Red Three


"Examining water, agriculture, and wet waste"

In the year 2050 it is projected that there will be 9.1 billion human beings on the planet, each person requiring 13.2 gallons of water a day to assure survival and meet basic needs; sanitation, bathing, cooking. Currently 884 million people lack access to safe water, mostly in developing countries. These countries lack the large scale infrastructure necessary to distribute water adequately and will be burdened with almost all of the projected population increases. These countries also lack infrastructure systems adequate to deal with wet waste disposal and to support agriculture. Large scale infrastructure is expensive and it is extremely unlikely that it will see significant developments. For this reason a move to on site methods of water and wet waste treatment will be necessary to support the growing population, in terms of sanitation, availability of potable water, and agriculture. This group blog will identify strategies for water conservation and reuse as well as how theses systems and methods can be combined with more effective wet waste disposal and efficient agricultural practices. Irrigation practices are evaluated and compared to real world irrigational issues in Jordan. Water reuse and wet waste disposal issues are also studied providing methods of effectively treating waste water for reuse agriculturally; real world applications in Peru are discussed. Additionally, Biogas digesters are an alternative waste treatement method that is investigated illustrating opportunities to dispose and reuse waste efficiently, applicable once again agriculturally. Finally, water supply and agricultural issues in mexico city are evaluated and possible solutions are investigated.
