Quy hoạch sử dụng đất bao gồm các quyết định về việc sử dụng đất và tài nguyên (Tổ chức Nông Lương 1993). Nó được thực hiện chủ yếu để đạt được việc sử dụng tốt nhất của đất, và thực hiện của nó thường được thúc đẩy bởi nhu cầu hiện tại và tương lai của người dân về năng suất và tính bền vững môi trường. Idand quy hoạch sử dụng có thể không quan trọng ở các nước và cộng đồng dân cư thưa thớt.

Looijen 11.1 INTRODUCTION Land use planning consists of making decisions about the use of land and resources Food and Agricultural Organization 1993 . It is conducted primarily to achieve the best use of land and its implementation is often driven by current and future people s needs in terms of productivity and environmental sustainability. Land use planning may not be as important in sparsely populated countries and communities. In sparsely populated countries or communities the land use planning is straightforward and is usually aimed at finding the best locations for each of the potential land uses at hand in other words it is reduced to a land evaluation FAO 1976 Rossiter 1996 . In highly populated communities however land use planning consists of a more elaborate analysis due to conflicts between competing uses Brinkman 1994 . In this case planning activities are tailored primarily to making the optimal uses of the limited land and associated resources. Land use planning may be conducted at different levels or scales of decisionmaking national district local farm or field level. The national level is concerned primarily with national priorities as driven by land use policy and legislation. In some countries land use planning consists of a multi-year program detailing goals at every step of the action plan. Land use planning at a district level often deals with development projects. Local planning may be carried out at the community or watershed level. Farm-level land use planning involves determining best management practices for different fields in the farm. The land use planning process differs from project to project depending on the goals and availability of data. Most projects involve sequential organization of thoughts evaluation and comparison of alternative land uses in terms of their suitability and impacts to .
