ThesisIn the past, the Ogallala has been a seemingly infinite supply of water however, current research has put an end to that as indicators of declining water levels are prompting a reexamination of farming conditions as well as a range of irrigation strategies to meet conservation goals.

Subtopic 1: Water DepletionTake-away: However, depleting at rates that are still being disputed one thing for certain is water usage must slow to preserve the life of the aquifer for years to come.Rate of declineV.L. McGuire, Terrell and JohnsonDiscussion on need for change in water usageTerrell and Johnson, Hornbeck

Subtopic 2: Irrigation MethodsTake-away: Modern irrigation techniques must be adopted as well as development of new ones for the overall goal of conserving the aquifer.Need for adoption of modern methods, due to inefficient old technologiesHornbeck, Keskin, Lamm and Obrian , Call for development of technologiesLittle, Lamm and Obrian , Verchick

Subtopic 3: Farming techniquesFarming habits are also crucial to alter if conservation will succeedReliance on irrigation Pfeiffer and Lin, LittleUsing farming techniques to conserve waterLittle, Castellazzi

ConclusionCurrent research indicates regardless of how fast, the Ogallala is depleting and it is the human responsibility to preserve it.Not only must water efficient irrigation methods be used more wide spread but also farming methods must change. Low-tillage farming and crop rotations are excellent alternatives.Continued research and adaption to the growing situation must continue to progress at a rapid pace to give the aquifer the best chance to be preserved.
