Earth is the home, mankind has been very concerned about their survival and development of the Earth's surface conditions, which sprouted out of a variety of geographical concepts. With the development of human society, the accumulation of geographical knowledge, and gradually formed a scientific study of nature and man and nature relationship, and is divided into physical and human geography. Simply put, the geography is to study the relationship between disciplines and the geographical environment, the aim of the study is to better development and protection of the natural resources of the earth's surface, to coordinate the relationship between the natural and human.
Geography is an old research project, has been called the mother of science. Ancient geography to explore the measurement method on the Earth's shape, size, or to describe the known regional and national. Traditionally, the geography in describing the situation in different regions and among the inhabitants of, on and history in close contact (such as Herodotus); in determining the size and location of the region of the Earth, astronomy and philosophy. German naturalist and geographer Alexander von Humboldt, a key figure in the rise of modern geography, because he made a precise measurement and careful observation record and the humanities and the natural features important regional types of mapping.
Geography refers only to the mapping and exploration of Earth's past, has become today a wide range of disciplines. Any type of spatial variation of the various phenomena on the surface of the Earth are subject to many factors affect the nature and human life, and thus the geographer must be familiar with the biology, sociology and to other disciplines. Desertification in Africa, for example, is often attributed to drought, but studies show, is due to overgrazing, agricultural over-expansion and deforestation, firewood exacerbated. Many phenomena of experts from other disciplines, but the special task of the geographer is a survey to study the distribution pattern of geographical cooperation network linking the various components, as well as its process of interaction.
