    Introduction to Land Economics: Scope and Content Concepts of Land Economics Land Resources Supply and Demand The Valuation and Use of Land Farmland Preservation

  • Introduction to LandEconomica:Scope and Content

  • Land economics deals with the economic relationships people have with others respecting land

    it is always concerned with problems and situations in which land,its use,or its control are regarded as factors of strategic or limiting importance.

  • Land economics:a branch of political economy

    Land economics is an applied branch of economics

    Land economists often step beyond the bounds of economics to operate as social science land specialists in the broader field of political economy

  • Threefold framework affecting land useThreefold framework involves Technological and economic considerationsInstitutional arrangements3Physical and biological factors12

  • Concepts of land Economics

  • Now, land economics has been tools of analysis. At this part, emphasis is given to three basic ideas.

  • 1.The economic concept of land and land resources

    2.A classification of land uses by type

    3.The concept of land use-capacity

  • The economic concept of land and land resourcesThe economic of land include the question about finger of landland usedistribution of land etc revenue Economic relations and issues of economic theory

  • A classification of land uses by type

  • 3.The concept of land use-capacity How to make the land have the highest use-capacity? Efforts were intensified to land more economically and intensively, resulting in continued improvement in land - use efficiency.

  • Land Resources Supply and DemandThe adequacy of our land resource base call for frequent use of the terms supply and demand.

    We will follow popular usage in speaking of supply as the quantity of goods or resources available for use and of demand as the amounts of a commodity people want and are willing to buy.

  • When we speak of the physical supply of land,we are concerned with the physical existence of resources.The economic supply of land involves only that portion of total physical supply that people want and use.The concept of demand is analogous to that of suppy.As a physical concept,demand is associated with desires,needs,and wants for commodities and services.

  • Under real market conditions,supply and demand fanctors tend to follow the model of the perfect market.

    The amount of any given land resources supplied or demanded are usually responsive to price changes but in most situations,supply and demand reponses tend to be inelastic.

  • The valuation and use of land Land use and valuation was an important concern in the early decades of modern economices, beginning in the late eighteenth centuryIn a sense, the study of land economics was the beginning of the economics of natural resources . land is clearly an important input factor into many economic activities-agriculture and forestry; residential, commercial, and industrial uses; and mineral exploration. it also supports an enormous variety of ecosystems. Land ownership was also for many centuries the key to personal wealth and social power. Our focus is on the economic principles surrounding the efficient use of land as a natural resource, the determination of the value of land, an how different types of ownership of land affects land use and value.

  • Farmland Preservation

  • IntroductionMany states have adopted a variety of farmland presetvation measures that inhibit urban development.

  • Arguments:Threats to national food security;the unproductivecharacteu of housing compared with productiveagricluture; the risk of more environmentaldegradation from prsticides if a smaller agricultural land stock is used more intensively;

  • There are many arguments on the other side:Lands highest and best use to urban boundaries can change from rural to urban;when it does,elementary models of land use show that markets will reallocate that land to its most valued use.

  • Food,resources,and peopleThe proportion of the labor force engaged in agricluture has fallen dramaticallyContrary to popular impression,food production per capita has been increasing for the half-century since World War ,the only decades for which we have acceptable data.

  • Land economicsLand economics shows that free exchange within a systerm of private rights leads to dfficient resource allocation.

  • ConclusionsA key institution in this success story is the market mechanism which,in turn,rests on the foundation of laws and property rights.
