Worldwide, many people consume a large portion of carbohydrates for their daily diet. Wheat is one of the major corps that helps to meet the world demand for carbohydrates. Globally, due to rising population, there is demand for food and it will continue to rise. The United States relies on wheat for carbohydrates. North Dakota is known as being a major producer of wheat in the United States such that wheat plays a major role in North Dakota’s economy. Global temperature and precipitation patterns are changing, and this is a regional issue in North Dakota affecting wheat production. The effects of temperature and precipitation change in North Dakota already has been observed such as shorter and milder winters. The research questions are: Do temperature and precipitation variability influence North Dakota spring wheat production; and what are the impacts on yield for spring wheat in the period of 1986-1990 compared to period of 1991-1995? The study area is the state of North Dakota and its 9 counties which are selected from 9 agricultural districts determined by the United States Department of Agriculture. For this study, my methodology includes excel data entry for temperature and precipitation creating maps in ArcGIS and producing statistical analysis to present tables and graphs. I anticipate to find with an increase in temperature spring wheat yield will decrease, but an increase of precipitation provides increased spring wheat yield. I expect to find that the State of North Dakota wheat yield is impacted differently by temperature and precipitation.
