The Market and Land Use
Why is a particular piece of land used in aparticular way ? One piece of land used for agricultural production, Another for an industrial site, and
A third piece of land used for office blocks.
QUALITY & LOCATION of a piece of land
KUALITAS LAHANKualitas lahan merupakan konsep “fungsional”, harus didefinisikan dalam kaitanhnya dengan aktivitas tertentu pemanfaatannya/penggunaannya.
Kualitas lahan untuk memproduksi tanaman tgt pd iklim, topografi, tipe tanah, dan kesuburannya; semua faktor ini berpengaruh pd pertumbuhan tanaman, biaya produksi dan biaya panen.
Setiap aktivitas penggunaan mempunyai persyaratan tertentu.
LOKASI LAHAN
Teori lokasi lahan ini pertama kali dikemukakan oleh von-Thunen dari Jerman.Teori ini berdasarkan pada biaya angkut hasil panen pertanian ke pasar.Nilai lokasi = f (biaya transportasi, jarak riil)
QUALITY OF LAND
A : lahan kualitasnya rendah unt memproduksi jagungB : lahan kualitasnya mediumC : lahan kualitasnya tinggi.

LOCATION OF LAND
Teori Lokasi ini pertama kali dikembangkan oleh von Thunen.Nilai lokasi sebidang lahan ditentukan oleh jaraknya dari pusat pasar; Jarak ini akan menentukan biaya transportasi hasil produksi lahan

Land Use Planning
Land use planning -------- Land Suitability Analysis (LSA)Tiga fase dalam LSA :1. Asses the requirements of potential activities2. Determine the capability of the land resources 3. Match land resources capability to the needs of society
Agricultural Land Use Planning (Teladan dari Young & Goldsmith)Enam alternatif penggunaan lahan adalah:1. Annual cropping 4. Natural forest2. Perennial cropping 5. Plantation forest3. Livestock 6. Tourism & Recreation.
(1). Asses requirements of potential activities

Suitability of land unit for arable cropping (Young & Goldsmith)
Land unit Drainase Bahaya erosi Zone perakaran Suitability
Lilongwe Mainly free drained Nil to Low Very good (deep Highly suitable (75% free, (Slope < 3%) well structured soil) (S1) 25% imperfect)
Thiwi Mainly free Low to medium Moderate Marginally(Slopes 6o) Soil depth < 100 cm suitable (S3)
Dedza Free Medium to high Poor (Shallow soils) Permanentlymountains (steep slopes) not suitable (N2)
Kesesuaian unit lahan untuk suatu aktifitas dinilai pd kisaran sekala:1. S1 : Highly suitable2. S2 : Moderately suitable3. S3: Marginally suitable4. N1: Currently not suitable 5. N2: Permanently not suitable.
Land Use Planning
(3). Match land resource capability to the needs of activitiesHasil LSA menyatakan “production possibility” untuk setiap land unit, belum mencerminkan “the best allocation”Alokasi penggunaan lahan lazimnya melibatkan kebijakan pembangunan daerah, sehingga seringkqali harus ada trade-off dalam pengambilan keputusan

Kelemahan LSA dari perspektif ekonomi:
1. Existing versus potential capability2. Location, biasanya berkaitan dengan biaya transportasi dan konservasi SDA3. External effects, biasanya berkaitan dengan pencemaran lingkungan
The Market and Land Use
An Introduction to Regional Economics ( Edgar M. Hoover and Frank Giarratani)http://www.rri.wvu.edu/WebBook/Giarratani/chaptersix.htm
The foundations for a systematic understanding of the principles of land use were laid more than a century and a half ago by a scientifically minded North German estate owner named
Johann Heinrich von Thünen.9 He set himself the problem of how to
determine the most efficient spatial layout of the various crops and other
land uses on his estate, and in the process developed a more general
model or theory of how rural land uses should be arranged around a market
town. The basic principle was that each piece of land should be devoted to the use in which it would yield the highest
rent.

What Is Land-Use Planning?
http://www.waterencyclopedia.com/La-Mi/Land-Use-Planning.html
As population and human aspirations increase, land becomes an increasingly
scarce resource, calling for land-use planning. Land-use
planning is important to mitigate the negative effects of
land use and to enhance the efficient use of resources with
minimal impact on future generations.
Land-use planning is defined as a systematic assessment of
land and water potential, alternatives for land use, and
the economic and social conditions
LAND-USE PLANNING
http://www.waterencyclopedia.com/La-Mi/Land-Use-Planning.html
Land and water resources are essential for farming, grazing, forestry, wildlife, tourism, urban development, transport infrastructure, and other environmental functions. The
increasing demand for land, coupled with a limitation in its supplies, is a major cause for more conflicts over land use throughout the world.
The Watershed Perspective Each type of land use has a varying effect on the hydrologic cycle , thereby affecting the people and the natural resources on a landscape. A watershed perspective can be used to
scientifically study the effect of land uses on water and downstream ecosystems . A watershed is defined as a topographically delineated area drained by a stream system; that
is, the total land area above some point on a stream or river that drains past that point. A watershed acts as a receiver, collector, and conveyer of precipitation on a landscape. Land uses affect these pathways by altering surface runoff and groundwater infiltration,
thereby changing the quantity and quality of water resources.

IMPACTS AND BENEFITS OF LAND USES
http://www.waterencyclopedia.com/La-Mi/Land-Use-Planning.html
Natural vegetation, such as forest cover, is usually the most benign of land uses, with higher infiltration and reduced runoff rates. The opposites of forest cover are urbanized areas, where large surface areas are impermeable, and pipes and sewer networks augment the natural channels. The impervious surfaces in urban areas
reduce infiltration and can reduce the recharge of groundwater. In addition, urban runoff contributes to poor water quality.
Agricultural activities are major forms of land use, including row crops, rangelands, animal farms, aquaculture , and other agribusiness activities.
Cropping activities involve soil and water manipulation through tillage and irrigation , thereby affecting runoff water and groundwater resources. If improperly used, fertilizer and plant protection chemicals in agricultural
operations can affect water resources and ecosystems.

LAND-USE PLANNING
http://www.waterencyclopedia.com/La-Mi/Land-Use-Planning.html
A typical planning process involves the following steps:
Establishing goals and a baseline; Inventorying and organizing resources;
Analyzing problems; Establishing priorities and alternatives;
Checking for land suitability; Evaluating alternatives and choosing the best option;
Developing a land-use plan; Consulting and implementing the plan; and
Revising the plan.

LAND USE, TRANSPORTATION, AND GROWTH
http://www.dot.ca.gov/ser/Growth-related_IndirectImpactAnalysis/gri_guidance.htm
The complex relationship between transportation, land use, and growth in a REGION context. It describes the causes of growth generally and the link
between transportation and growth specifically. Highway projects can affect the location, rate, type, or amount of growth in an area. Some types of development may be directly induced by a project (e.g., projects serving specific types of land
development). However, most land use changes in a REGION are not direct consequences of a highway project, but rather occur indirectly due to changes in
travel time and increased land accessibility in areas that may be ripe for development.
The result may be a change in spatial distribution of development over time, such as commercial development around a new highway interchange. These types of growth-land use-transportation relationships are more complex and
difficult to analyze than those for a project specifically designed to encourage or facilitate land use change and development.
