Indonesian food production depends highly on Java Island, which holds the most fertile soils in the country but had limited area. The objective of the research was to analyse the availability of suitable land for agriculture in Tuban Regency, an agricultural regency in Java Island. Land suitability was evaluated with spatial multicriteria analysis, integrating soil order, land capability, elevation, slope, slope direction, land use/land cover, accessibility, and climate. Land availability was analysed, integrating the forest area status designation and the spatial pattern of regional official land use plan. The results indicated that suitable land for agriculture corresponds to 91% of the total study area, confirming the high soil fertility. Analysis of land availability then indicated that 18% of the area was both suitable and available for agriculture. Considering the actual land utilization, the future development of agriculture in the region has less than 7% of the land area left for agricultural expansion. The overall results showed the importance of looking for land allocated for agriculture outside Java Island to anticipate the need for food of a country with a high population growth rate and also developing planning for food production.

Land use planning is an important task for every country in the world to ensure the sustainable use of land resources for economic and social development activities. However, many land use plans have not achieved their desired effectiveness due to a lack of consideration and evaluation of factors affecting the land use planning implementation process. This study was conducted to answer the following question: what are the main factors influencing the land use planning process in Vietnam? In this study, we use multivariate regression to identify the main factors influencing land use planning in Vietnam, including the economic factor group; institutional and policy factor group; urbanisation factor group; planning factor group; social factor group; environmental factor group; and organisational and implementation factor group. The results identified five groups of factors influencing land use planning in the Dan Phuong district through the influencing factor analysis method, including policy (Po), economy (Ec), society (So), environment (En), and others (Ot). In addition, the linear regression model obtained for land use planning in Dan Phuong district is as follows: land use planning = 0.408Po + 0.454Ec + 0.398So + 0.368En + 0.259Ot. In which the group of factors with the strongest influence was the Eco factors (β = 0.454), the second was the Po factors (β = 0.408), the third was the So factors (β = 0.398), the fourth was the En factors (β = 0.368), and lastly, there were the Ot factors (β = 0.259). The results of the analysis were used to plan land use effectively and according to local conditions. This can help managers to find solutions for the sustainable use of land resources in the future.

Landuse planning for food crop areas development using land resource evaluation approach and gis application (a case study of Pulang Pisau District, Central Kalimantan Province). Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 64-72.In order to promote sustainable landuse, the need of landuse planning is urgently required and it can be designed based on the result of spatial land resource data management. Land resource evaluation is main component for landuse planning which this procedure was applied to determine land allocation for arable lands for rice farming development. The use of geographic information system (GIS) technology was also employed not only for spatial data management, but they could also be applied to support decision making within establishing landuse planning. The objective of this study was to allocate the arable lands for extensification and intensification regions as main part of landuse planning for ...

Land use planning based on land resource evaluation and spatial orientation of planning as part of GIS may ensures appropriate land allocation in order to achieve sustainable agriculture. The combination of some land resource evaluation can provide final results on rational land allocation and land utilization based on land capability and suitability. Land capability evaluation (LCE) and land suitability evaluation (LSE) approach rooted from USDA and FAO was used in this study to allocated arable land as agricultural developed areas and determine prime commodities spatially. The principle of limiting condition was used for LCE to define land class and determine land availability for agriculture. While, for LSE, procedure of matching between land quality/characteristics and crop requirement will be scored according to limitation method and class criteria of land suitability in order to define the most suitable crop considered as prime commodity. The objective of this study was to det...

The study was conducted using existing soil data from Nawagaon and Maskara Rao watershed boundary in Shaharanpur district, India to assess land capability classes using Remote Sensing and GIS approach. Land sat image was integrated with SRTM DEM for delineation of landforms and analysis of land use/land cover data. The filled SRTM DEM of the study area was extracted at 30 m resolution to extract terrain parameters such as elevation, slope and aspect. SRTM DEM was visually interpreted. Three major landforms were identified, namely, 3 landforms-hills, piedmont plains and alluvia plains. These were further delineated according to slope and finally according to vegetation cover to give eight physiographic units. The slope map and aspect map were produced using filed Dem and were classified into nine and two classes respectively. Land use/land cover map was also generated using satellite image for the study area in India. The dominant land use was: dense forest, degraded forest, crop land I, crop land II, scrub/barren, settlement, river, canal and road. Based on the slope map, land characteristics of each physiographic unit and land capability criteria for land qualities, land capability classes were assigned and were translated into a land capability map. The soils were placed in seven classes (I, II, III, IV, VI, VII and VIII). Both the GIS approach and LCC evaluation using criteria rating of FAO gave the same classes for the mapped soil. The study revealed that soils from the study areas varied with different physiographic unit, therefore soils of the hilly areas should be put to use for nature conservation other than arable production while the lower portion should be cultivated with intensive care for arable crops. Land is one of the most important natural resources, which plays an important role in the economic life of a majority of people in the world. Land is a limited resource and with increasing population, the demands for land become more competitive. Any given area of land can have a multiple of potential uses and may need to be considered in planning land resources. Soil is also a product of interactions among parent material, relief, climate, organisms over

To support the goverment purpose to reach the food security, a land use study is needed. The aim of the research was to provide an information of characteristics of land resources through the identification and evaluation of potential landresources and that suitable for food crops in Mamuju District South Sulawesi. The research method used landscape approach to mapping land units as the basis for preparing the soil map unit/DEM compared with field data survey. A case study was done in Mamuju District, West Sulawesi the results showed that the land in Mamuju for paddy covering was suitable enough of 115,250 ha and 54,883 ha of marginal fit, while for dryland crops were 106 978 ha was quite suitable and appropriate marginal was 82,592 ha. However, for cocoa fit enough land was 153,397 ha and corresponding marginal was 485,743 ha. Biophysical constraints were the erosion of land use/steep slopes, drainage, seasonal flooding, toxicity and nutrient retention. Direction of land u...
Soil and Land Resources Evaluation Report of Calayan, Cagayan
The soil and land resources evaluation of Calayan was conducted as input to the comprehensive development town planning. The results were used in rating the suitability of the area to various crops that were thought to be economically important and relevant to the area. This report also served as input to the formulation of more appropriate agricultural and fisheries development zoning in accordance with Republic Act 8435 known as Agriculture and Fisheries Modernization Act.
