From conducting a review of the scientific, peer-reviewed literature, we have identified the following major world challenges related to soil and water conservation:• Climate change is occurring, and the implementation of sound conservation practices will be key for each country's health, social stability, and security.There are a large number of peerreviewed publications that report on the effects of a changing climate.The potential role of conservation practices in contributing to food security is shown in figure 1, which illustrates the relationship between climate change, soil and water resources, and food security.• Extreme weather events are creating environmental problems, accelerating the rate of erosion, and threatening agricultural production needed for food security.Increases in erosion rates due to climate change will result in lower productivity.Additionally, Hugh Hammond Bennett suggested that without conservation of natural resources, environmental problems such as accelerated erosion could negatively impact society and threaten national security (USDA NRCS n.d.).• Population growth and the development of new, stronger economies, such as those of China and India are increasing the demand for world resources.
