<p><strong>English</strong><br />The objective of this paper is to provide a comprehensive information on performance development and problems associated with land resource utilisation and its future management perspective. The coverage of discussion to identify such objectives could be divided as follows: (1) perception and concept of land resource, (2) the development of land resource, (3) the importance of land resource, (4) land resource and agricultural production stability, and (5) discussion on policy alternatives to overcome land resource problems. Some important findings could be described as follows: (1) various concepts and ideas on land resource have led to a thought that land resource has social, economic, political values, and a symbol at a certain level as a production factor in agricultural sector, (2) land resource development has changed land resource institutions, land fragmentation, land transfer to other non-agricultural utilization, land value improvement, and polarization and absentee practices, (3) various development activities has reflected the importance of land resource and the highly competitiveness of land utilization in line to the importance of each activity and each sector, (4) acting as a stabilizer in agricultural production, the land resource has faced many problems both in current time or in the future especially those associated with agricultural land degradation reducing land fertileness that ended in marginal land accumulation, in the mean time, food-self sufficiency should be continuously maintained, (5) although all problems on land affairs have been arranged in the UUPA since September 1960; Keppres No. 53/1989 or Keppres No. 33/1990, the problems continually appeared. In this regard, governor, based on Permendagri No. 15/1975, as an officer authorized to issue land utility permit, should launched policies which are very much expected to harmonize the central and local requests, the government and the people, agricultural and nonagricultural sectors, or individual/group requests and the society's needs on land resource.</p><p> </p><p><strong>Indonesian</strong><br />Tulisan ini bertujuan untuk memberikan informasi tentang perkembangan keragaan dan permasalahan pemanfaatan sumberdaya lahan serta perspektif penanganannya di masa datang. Identifikasi ke arah tersebut dilakukan melalui beberapa subpokok bahasan yang meliputi : (1) persepsi dan konsepsi terhadap sumberdaya lahan, (2) perkembangan sumberdaya lahan berdasarkan waktu, (3) kepentingan terhadap sumberdaya lahan, (4) sumberdaya lahan dan stabilitas produksi pertanian, dan (5) pemikiran terhadap kebijaksanaan dalam mengatasi permasalahan sumberdaya lahan. Beberapa temuan penting yang perlu dikemukakan adalah : (1) beragamnya konsep serta pandangan sumberdaya lahan dalam arti luas memberikan gambaran bahwa sumberdaya lahan mempunyai fungsi sosial ekonomi, politik, serta simbol status tertentu selain sebagai faktor produksi di sektor pertanian, (2) perkembangan sumberdaya lahan berdasarkan waktu telah membawa perubahan terhadap kelembagaan sumberdaya lahan dengan adanya kegiatan fragmentasi lahan, alih fungsi lahan pertanian ke nonpertanian, peningkatan nilai lahan, terjadinya polarisasi ataupun praktek-praktek absentee, (3) adanya berbagai kegiatan pembangunan menjadikan sumber daya lahan sebagai asset yang cukup penting, sehingga terjadi persaingan penggunaan yang cukup meningkat sesuai dengan kepentingan antar aktivitas maupun antar sektoral, (4) sebagai stabilisator bagi produksi pertanian, sumberdaya lahan dihadapkan pada persoalan yang cukup berat baik saat ini dan juga di masa yang akan datang terutama dengan meningkatnya degradasi lahan pertanian, penyusutan lahan produktif yang digantikan dengan lahan marjinal, sementara kebutuhan akan swasembada pangan tetap harus dipertahankan, (5) walaupun secara yuridis permasalahan pertanahan telah diatur dalam UUPA sejak September 1960, Keppres No.53/1989 ataupun Keppres No.33/1990, persoalan mengenai lahan tetap meningkat. Untuk itu kebijaksanaan dari gubernur sebagai pejabat yang berwenang dalam pemberian izin penggunaan lahan sesuai dengan keputusan Permendagri No.15 Tahun 1975 sangat diharapkan sekaligus mampu menselaraskan perbedaan kepentingan antara pusat dengan daerah, penguasa dengan rakyat, sektor pertanian dengan nonpertanian, ataupun kepentingan individu/golongan dengan masyarakat luas terhadap kebutuhan sumberdaya lahan.</p>

Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: practical guidelines on the soil physical measurements across a range of soils, climates and land uses; straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.

Income Stream

A use-value assessment tax requires a system by which agricultural land values may be established. Land value in agricultural use can in principle be determined from the land's income-generating ability. The value of agricultural land can be based upon the capitalized income stream, which implies that net income attributable to land resource, or more theoretically, its value of the marginal product, can be capitalized into economic value. A major weakness in the process of determining net returns to land is the requirement that returns to other production inputs can be determined accurately. To be exact, the marginal productivity of every input must be known.

Land is becoming scarce resource due to population growth and industrialization. Rapid growth of human activities can also be attributed as one of the reasons. Thus, it becomes an important task to regulate land resource for sustainable development and environmental protection. LULC change studies have become a central component in current strategies for managing and planning land resources and monitoring environmental changes. In this paper an attempt has been made to bring out spatio-temporal dynamics of LULC patterns of NTPCRamagundam and its surrounding environment by using multi-temporal satellite data of Landsat-4, IRS P6 LISS-III and IRS 2 LISS-IV and GIS techniques for the years 1984, 2005, 2011, 2015, 2018. The methodology includes base map preparation having features like Road (SH), Rail, Canal, River, Stream, Tanks, Forest boundary and other administrative boundaries from SOI topo sheet and the features digitized are updated on satellite images. Interpretation of study area for LULC feature extraction on satellite imageries of respective years is carried with Nrsc’s standard LULC classification system. Change detection statistics can be generated out of 5 LULC thematic layers obtained and analysed specially with respect to NTPC environs. Results from this study shows the percentage of geographical area occupied by built-up land, agricultural land, forests, wasteland and waterbodies of level-I LULC features were 10.27%, 60.68%, 6.61%, 11.81%, 10.63% respectively in 1984 and were changed into 21.41%, 48.51%, 5.97%, 12.77%, 11.34% respectively in 2018. This analysis shows a rapid growth in built-up land and fall in agricultural land between 1984 and 2018. There is a considerable change in the remaining features from 1984 and 2018.

<p class="Isi"><strong>Abstrak.</strong> <span>Permasalahan pupuk, lahan terdegradasi, dan pencemaran, pengelolaan sumberdaya lahan rawa, dan pengelolaan sumberdaya air yang terbatas di lahan pertanian, merupakan isu atau permasalahan mendesak yang harus dicari pemecahannya. Untuk mengatasi permasalahan tersebut, Balai Besar Litbang Sumberdaya Lahan Pertanian (BBSDLP) telah menghasilkan beberapa teknologi yang siap diaplikasikan. Dalam dua tahun terakhir, output hasil penelitian BBSDLP tersebut dalam bentuk produk teknologi dan rekomendasi anjuran teknologi sumberdaya lahan telah diaplikasikan dan dimanfaatkan dalam mendukung program prioritas sektor pertanian. Program prioritas dimaksud, adalah: (1) program selamatkan rawa dan sejahterakan petani disingkat SERASI, (2) program penurunan pencemaran lingkungan, (3) program peningkatan produktivitas pertanian dan (4) program antisipasi perubahan iklim. Terdapat opini yang paradoks, institusi lembaga riset menganggap bahwa banyak teknologi hasil penelitian yang siap diaplikasikan, tetapi menurut sebagian petani sangat terbatas teknologi hasil penelitian yang siap dimanfaatkan petani. Untuk itu perlu analisis secara seksama sehingga memperoleh gambaran yang akurat dan dimana letak permasalahannya serta bagaimana cara mengatasinya agar teknologi hasil penelitian tersebut efektif. Hasil evaluasi awal beberapa teknologi yang dimanfaatkan dalam program prioritas tersebut telah menunjukkan nilai tambah atau nilai indeks efisiensi teknis dalam bentuk meningkatkan produktivitas hasil (sekitar 30%) atau efisiensi penggunaan input produksi (contohnya mengefisiensikan penggunaan pupuk N,P sebesar 20%), walaupun masih perlu kajian lebih lanjut, apakah teknologi tersebut berpotensi memberikan dampak potensial (<em>potential impact</em>). Sebagian besar teknologi unggulan tersebut menunjukkan dampak awal (<em>initial impact</em>) yang positif dalam bentuk penyebaran dan aplikasi teknologi oleh petani di wilayah pengembangan</span>. </p><p class="Isi"> </p><p class="Isi"><em><span lang="EN-ID"><strong>Abstract.</strong> The problem of fertilizer, degraded land, and pollution, management of swampy land resources, and management of limited water resources on agricultural land, are urgent issues or problems that have to be resolved. To overcome these problems, ICALRD has produced several technologies that have been and are ready to be applied. In the last two years, it has been shown that some of the outputs of research results in the form of technological products and recommendations for land resource technology have been applied and utilized in supporting the priority programs in the agricultural sector. The priority programs referred to are: (1) safe the peat swamp and increased farmer’s welfare program abbreviated as SERASI, (2) environmental pollution reduction program, (3) agricultural productivity improvement program and (4) climate change anticipation program. There is a paradox opinion between beween research institute and farmers; where many technologies have been resulted by research institute and ready for application but according to some farmers only few technologies are available and applicable. For this reason, a careful analysis is needed to assess what the problems are and how to overcome them so that the research technology is more effective. Initial evaluation results of several technologies utilized in the priority program have shown the added values or technical efficiency index values in the form of increasing yield productivity (around 30%) or efficient use of production inputs (eg efficient use of N, P fertilizers up to 20%). However, there is still a need for further study to determine whether the technology is promishing to have a potential impact. Most of the leading technologies show positive initial impacts in the form of technological dissemination and application by farmers in development areas.</span></em></p><p align="center"><strong><br /></strong></p><p align="center"><strong> </strong></p><p> </p>

Enterprise Budgets

Spatial linear programming studies in agriculture require establishment of a land resource base so representative enterprise budgets can be constructed to reflect productivity and limitations of each region's agricultural land. To relate the land base to budgeting procedures requires an economic classification of agricultural soils. Ideally, this classification would group together those soils requiring similar cultural practices and having the same yield capabilities. Costs and returns can then be computed for selected agricultural enterprises within each classification. Technical information on agronomically based soil classifications is available through agricultural experiment station reports and the Soil Conservation Service. These reports give an abundance of detailed physical and chemical soil data on a county basis.Because technical data are extensive, a problem exists in translating this information into economic groupings suitable for use in constructing budgets. Economic classification of soils for a spatial study should be pragmatic but detailed enough to ensure a meaningful linkage of enterprise budgets to the soil.
