Abstract After New Yogyakarta International Airport (NYIA) opening, Kulon Progo continues to develop, one of which is The Bedah Menoreh route project which passes through the mountainous region. The development encourages agricultural land conversion, which impacts food security in Kulon Progo, especially in the mountainous region. This study aims to identify the conversion of agricultural land in the mountainous region of Kulon Progo Regency in 2005 – 2020 and analyze its impact on regional food security. The method used is a Normalized Difference Vegetation Index (NDVI) on Landsat Imagery using Machine Learning through Google Earth Engine (GEE) to identify land-use change and mathematical calculations in analyzing regional food security. The result of the supervised classification is a land cover map of the mountainous region of Kulon Progo Regency, which shows that every year the area of rice fields, in general, continues to decrease until 2020 the total area is 2,102.79 ha with a rate of agricultural land conversion -114.87 ha/year. It causes regional food security to be in a food-insecure condition, even though the availability of rice fields can be used for food self-sufficiency for up to 53 years. Other factors such as climate, rice seeds, soil, and water quality, in this case, are quite influential in rice production, not only productivity and agricultural land area.

Abstrak  Pertumbuhan  penduduk dan dinamika pembangunan telah menggeser pemanfaatan lahan yang akhirnya menimbulkan kompleksitas permasalahan lahan yang semula berfungsi sebagai media bercocok tanam (pertanian), berangsur-angsur berubah menjadi multifungsi pemanfaatan. Berubahnya pemanfaatan lahan pertanian ke non pertanian dapat disebut juga sebagai alih fungsi lahan. Kabupaten Aceh Besar adalah salah satu kabupaten yang terus menghadapi permasalahan alih fungsi lahan, khususnya lahan sawah. Alih fungsi lahan ini mengakibatkan luas lahan sawah di Aceh Besar terus menurun. Lahan yang paling banyak mengalami alih fungsi lahan adalah jenis lahan sawah yang menjadi lahan non pertanian. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang menyebabkan terjadinya alih fungsi lahan sawah dan mengidentifikasi dampak sosial dan ekonomi yang dialami petani mantan pemilik lahan akibat alih fungsi lahan sawah menjadi lahan non pertanian. Berdasarkan hasil regresi secara parsial dari analisis regresi faktor harga jual, kebutuhan hidup dan kondisi lahan berpengaruh nyata terhadap konversi lahan sawah di  Kecamatan Baitussalam Kabupaten Aceh Besar. Bedasarkan hasil regresi secara serempak dari hasil regresi didapatkan bahwa harga jual, kebutuhan hidup dan kondisi lahan secara serempak mempengaruhi konversi lahan sawah di Kecamatan Baitussalam Kabupaten Aceh Besar. Berdasarkan isu dampak sosial sebagai akibat alih fungsi lahan di lihat dari keinginan kondisi lama, meningkatkan rasa kerjasama dan kekeluargaan, serta kemampuan memenuhi kebutuhan keluarga mendapatkan hasil yang positif dengan nilai ≥ 50%. Berdasarkan isu dampak ekonomi sebagai akibat alih fungsi lahan di lihat dari peningkatan pendapatan mendapatkan hasil yang positif dengan nilai ≥ 50%.Impact Of Paddy Fields Function  On Community Socio-Economic Conditions Of Baitussalam District, Aceh Besar RegencyAbstract  Population growth and the dynamics of development have shifted land use which eventually led to the complexity of the problem of land that used to function as a farming medium (agriculture), gradually becoming a multifunctional use. Changing the use of agricultural land to non-agriculture can also be referred to as land conversion. Aceh Besar District is one of the districts that continues to face the problem of land conversion, especially rice fields. The conversion of this land function has caused the area of paddy fields in Aceh Besar to continue to decline. The land that has experienced the most land use change is the type of rice field that becomes non-agricultural land. This study aims to identify the factors that cause the conversion of paddy fields and identify the social and economic impacts experienced by farmers former landowners due to the conversion of paddy fields to non-agricultural land. Based on the partial regression results from the regression analysis, the factors of selling price, life necessity and land conditions have a significant effect on the conversion of paddy fields in Baitussalam District, Aceh Besar District. Based on the simultaneous regression results from the regression results, it was found that the selling price, life needs and land conditions simultaneously affected the conversion of paddy fields in Baitussalam District, Aceh Besar District. Based on the issue of social impacts as a result of land use change seen from the desires of the old conditions, increasing the sense of cooperation and kinship, as well as the ability to meet family needs get positive results with a value of ≥ 50%. Based on the issue of economic impact as a result of the transfer of land functions, it can be seen from the increase in income that has a positive result with a value of ≥ 50%.

Kabupaten Sleman memiliki banyak daya tarik yang memicu terjadinya urbanisasi yang dapat terlihat dari fenomeno perubahan penggunaan lahan . Perubahan penggunaan lahan di Kabupaten Sleman terjadi pada kawasan keamanan dan ketahanan pangan yang terdiri dari Kecamatan Moyudan, Minggir, Sayegan, Godean, Mlati, dan Tempel.  Fenomena perubahan penggunaan lahan penting untuk dikontrol dan dikendalikan karena kawasan tersebut memiliki peran penting bagi ketahanan pangan di Kabupaten Sleman. Metode penelitian yang digunakan adalah metode deskriptif. Di dalam metode deskriptif terdapat metode survey yang digunakaan untuk mengetahui kondisi eksisting penggunaan lahan di daerah penelitian. Sedangkan untuk perubahan penggunaan lahan pada kawasan keamanan dan ketahanan pangan di Kabupaten Sleman dari Tahun 2012 sampai Tahun 2018 diperoleh dengan metode overlay peta penggunaan lahan yang diperoleh dari Citra Quickbird pada tahun tersebut. Perubahan penggunaan lahan pada kawasan keamanan dan ketahanan pangan Kabupaten Sleman mencapai 57,33 km2 atau 33,93% dari luas total daerah penelitian. Perubahan penggunaan lahan didominasi oleh perubahan lahan sawah menjadi hutan produksi seluas 15,05 km2. Faktor pendorong adanya perubahan penggunaan lahan tersebut adalah produktivitas pertanian sawah yang semakin menurun tiap tahunnya.Sleman Regency has many attractions that trigger urbanization which can be seen from the phenomenon of land-use change.

Recently the strategic roles of paddy commodity at Poso Regency deal with serious challenges, one of them is the problem of agricultural land conversion as the consequences of rapid regional economic development. Land conversion associates with the fact that many people have not yet known and realized the concepts of economic value and the sustainability of paddy fields as well as the multifunctionality concept. Paddy fields are only considered as the tangible and marketable food products in the form of rice, whereas the another functions which relate to the aspects of environmental, social, and cultural are not much familiar even tend to be denied. Besides the producer of rice product, paddy field agriculture has another functions as to reduce the risk of flood downstream, to control erosion and sedimentation of waterways, to preserve water resources, to improve local climate, to decrease the accumulation of organic wastes, to become the habitat of flora and fauna, to maintain social and cultural values as well as rural attraction, to provide work field, and to support household and regional food security. There are some valuation methods to quantify the values of those functions. The valuation of agriculture multifunctionality indicates that paddy field has real economic value which is higher than that of conventional accounting results, so that paddy fields contributes to society economically, socially, culturally, and environmentally.

 AbstrakKabupaten Sukoharjo merupakan kota satelit yang memberi daya dukung bagi kota utamanya (Kota Solo). Pembangunan Kawasan Solo Baru dan Kartasuro sebagai kota satelit mandiri dengan konsep permukiman yang didukung oleh ketersediaan fasilitas penunjang akan berimbas pada perubahan pemanfaatan lahan. Kabupaten Sukoharjo sebagai salah satu lumbung beras nasional justru perlu diperhatikan dan dijaga. Keberadaan lahan pertanian (pangan) di Kabupaten Sukoharjo menjadi terancam oleh intensitas pembangunan kota yang mengarah pada alih fungsi lahan non terbangun (lahan pertanian) menjadi terbangun. Penelitian ini bertujuan: (1) menganalisis kebutuhan dan ketersediaan pangan, (2) menganalisis daya dukung (Carrying Capacity) lahan pertanian dalam mendukung ketahanan pangan, dan (3) melakukan estimasi kebutuhan lahan pertanian pangan di Kabupaten Sukoharjo. Sebesar 44,16% (20.617 ha) lahan di Sukoharjo diperuntukkan untuk sawah. Daya dukung pangan secara keseluruhan di Kabupaten Sukoharjo mampu tercukupi ditunjukkan dengan nilai 1,62 yang berarti bahwa kebutuhan pangan mampu dicukupi dengan luas lahan pertanian dan produksi padi yang dihasilkan saat ini. Kebutuhan lahan pertanian pangan berkelanjutan (KLP2B) menurut kecamatan di Kabupaten Sukoharjo yang masih belum dapat dipenuhi kebutuhan pangan di wilayahnya adalah Kecamatan Kartasura. Hingga 20 tahun ke depan (2031), KLP2B yang tinggi di Kabupaten Sukoharjo masih berada di Kecamatan Grogol, Kecamatan Kartosuro, Kecamatan Mojolaban dan Kecamatan Sukoharjo.Kata kunci: ketahanan pangan, daya dukung, pembangunan wilayah AbstractSukoharjo Regency is a satellite city that provides support for its main city (Solo City). The development of Solo Baru and Kartasuro areas as self-contained satellite cities with the concept of settlements supported by the availability of supporting facilities will impact on land use change. Sukoharjo Regency as one of the national rice granary precisely needs to be considered and maintained. The existence of agricultural land (food) in Sukoharjo Regency becomes threatened by the intensity of urban development that leads to the conversion of non-built land (agricultural land) to be built. This study aims to: (1) analyze the need and availability of food, (2) analyze the carrying capacity of agricultural land in supporting food security, and (3) estimate the needs of food agriculture land in Sukoharjo Regency. A total of 44.16% (20,617 ha) of land in Sukoharjo is reserved for rice fields. The food carrying capacity in Sukoharjo Regency as a whole is sufficiently indicated by a value of 1.62 which means that food needs can be satisfied with the existing area of agricultural land and rice production. The need for sustainable agricultural land (KLP2B) in Sukoharjo Regency that has not been fulfilled by the needs of food in its area is Kartasura District. Until the next 20 years (2031), high KLP2B in Sukoharjo Regency is still in Grogol District, Kartosuro District, Mojolaban District and Sukoharjo District.Keywords: food security, carrying capacity, regional development

The change in land-use over a certain period of time is inevitable. This paper investigates the issue of land use change on agricultural land that has become a phenomenon affecting the economy and environment in Kabul, the capital city of Afghanistan. Agriculture is the main economic source of Afghan cities, however, due to rapid population growth, population densification, and inability to apply Kabul city’s master plan and regulations, a large portion of land cover transformed from agricultural areas to unplanned developments and have shifted the function of communities from productive societies into consumer and dependent societies. The study sheds light on Yakatoot as a study farmland area in Kabul city to present an alive example of what is happening in the reality of agricultural land in Kabul. Therefore, approaches for sustainable conversion of agricultural land in Kabul city is a vital quest that needs to be followed seriously. The study illustrates Afghanistan's land laws. It identifies the social, economic and environmental impacts of land-use change. This paper applies qualitative methods, where data and analysis worked by using field surveys, aerial photographs from Google Earth and data collected from CRIDA. It also investigates international experience regarding land-use change and sustainable solutions. Therefore, due to positive implications of urban agriculture practice as a feasible and sustainable approach to tackle the ongoing challenges related to land-use change in Kabul city, this paper suggests inducing this approach in Kabul city’s master plan and other urban initiatives because it will not only lead to environmental protection, but also, it will re-establish economic stability, enhance social welfare, revive city’s historic identity.
