Agricultural Land Conversion and Land Use Change Dynamics in North Bandung Area

Abstract

Agricultural land conversion is considered as one of an important issus in the developing areas. In spite of theimportance of informations on the quantity and the rate of land conversion as the basis of formulating the agricultural landconversion policy, those informations are limited. This research was conducted at Lembang and Parongpong Sub-District,Bandung District. The objectives of research are to identify the rate of agricultural land conversion and to measure thedynamic change of land use. Land use in 1992 and 2002 was evaluated by interpretating the result of 1992 and 2002 landsatimage using Geographic Information System (GIS) program. Shift Share analysis was conducted to know the dynamic changeof land use. Results of the study indicated that land conversion at Lembang and Parongpong Sub-District during the period of1992-2002 (ten years) about 3,134.49 ha (25%) or 313.5 ha (2,96%) per year. Forestland reduced the most, from 5,470 ha in 1992 to 1,746 ha in 2002 or reduced about 3,732.12 ha (68%) in ten years. While area of the bush was increased about2,780.20 ha (1,326%) during the same period, from 210 ha in 1992 to 2,990 ha in 2002. Low land was decreasedfrom 252 hain 1992 to 95 ha in 2002, up land was decreased from 3,856 ha in 1992 to 2,736 ha in 2002, mix farming was increasedfrom2,491 ha in 1992 to 4,358 ha in 2002, resettlement was increased from 359 ha in 1992 to 1,612 ha in 2002, bare wasdecreasedfrom 1,115 ha in 1992 to 217 ha in 2002, lake was decreasedfrom 52 ha in 1992 to 50 ha in 2002.

Karakteristik Kandungan Volumetrik Air Dan Konduktivitas Air Pori Tanah Lahan Pertanian Dan Bukan Pertanian Desa Ciwaruga Lembang Bandung Barat

“…Ciwaruga merupakan salah satu desa yang berada di wilayah Lembang dengan kondisi geologi tersusun oleh lapisan tufa pasir yang berasal dari erupsi Gunung Tangkuban Parahu, mencirikan lahan pertanian yang terbentuk dari tanah vulkanik yang disebut juga sebagai tanah Andosol [8]. Secara umum desa Ciwaruga merupakan desa dengan produksi utama bidang pertanian dan memiliki komoditas unggulan hortikultura [9]. Sifat listrik tanah yang diukur pada penelitian ini selanjutnya dianalisis menggunakan pendekatan kualitatif untuk meneliti karakteristik perubahan tanah akibat penggunaan tanah sebagai lahan pertanian dan perbandingannya dengan tanah yang belum digunakan sebagai lahan pertanian.…”

Modeling of land use and cover changes (LUCC) in Deli Serdang Regency, North Sumatra Province

“…This condition causes competition in land demand for particular needs and encourages changes in land use or land conversion. According to Rustiadi (2007), LUCC can be considered a logical consequence of the growth and transformation of changes in developing societies' social and economic structure. These developments are reflected in the presence of (a) the growth of land resource utilization activities due to the increasing population and (b) a shift in the contribution of the agricultural and natural resource processing sectors to the activities of the secondary (manufacturing) and tertiary (services) sectors.…”

“…In addition, administratively, Deli Serdang Regency is directly adjacent to Medan City and is a hinterland that supplies land needs, especially for residential and industrial areas. In addition, the issue of conversion of agricultural land is considered one of the primary issues in developing areas, even though the policy for controlling the conversion of agricultural land based on this information is still limited (Ruswandi et al 2007). Therefore, it is necessary to restrain the conversion of paddy fields amid massive development activities in various sectors, such as roads, industrial areas, and other public facilities.…”
