Abstract. Lahan gambut telah menjadi target perluasan lahan pertanian/perkebunan, karena lahan pertanian/perkebunan yang sudah semakin menipis. Seperti yang terjadi di Kawasan Suaka Margasatwa Rawa Singkil, sudah banyak terjadinya deforestasi lahan gambut dan adanya kegiatan konversi lahan sehingga terganggunya fungsi gambut sebagai habitat untuk perlindungan keanekaragaman hayati sekaligus pengatur tata air. Tujuan dari penelitian ini adalah untuk mengetahui kondisi eksisting kawasan Suaka Margastwa Gambut Rawa Singkil . Penelitian ini menggunakan metode deskriptif melalui survei lapangan dan pengamatan lapangan. Tahapan awal yang dilakukan adalah analisis tutupan lahan dari hasil klasifikasi citra google earth 2019, selanjutnya Ground Check dan Meng-update/ memperbaiki/ memverifikasi peta yang telah dibuat. Berdasarkan hasil perbaikan peta gambut Suaka Margasatwa Rawa Singkil yang telah dibuat maka didapat  Hutan rawa sekunder seluas 15.313,53 ha (87,75%), semak belukar rawa seluas 2.066,25 ha(11,84%), telah terjadi deforestasi lahan  seluas 62,50 ha (0,36%) dan terjadinya konversi hutan menjadi perkebunan kelapa sawit seluas 8,51 ha (0,05%), dari luas kawasan Suaka Margasatwa gambut Rawa Singkil yaitu 17.450,79 ha.Study of Existing Condition of Rawa Singkil Peat Wildlife Reserve AreaAbstract. Peatlands have become a target for agricultural land, because agricultural land which dwindling. It was happened in the Rawa Singkil Wildlife Reserve Area, present day there is so many displacing peatland deforestation and land conversion so that the function of peat as a habitat for biological conversion as well as regulating the air system. The purpose of this study was to study the existing conditions of the Singkil Peat Swamp Margastwa Sanctuary. This research is using descriptive methods through field surveys and field observations. The initial stage is to analyze of land cover from the results of the 2019 google earth image classification, then ground check and updating / repairing / updating the maps that have been made. Based on the improvement of the Singkil Wildlife Reserve peat map that has been developed, a secondary swamp forest of 15,313.53 ha (87.75%), 2,066.25 ha (11.84%) of swamp shrubs has been successfully allocated 62,50 ha (0.36%) and conversion of forest to oil palm plantations of 8.51 ha (0.05%), from the area of the Rawa Singkil Peat Wildlife Reserve which is 17,450.79 ha.

The exploding demand for palm oil in the world market makes oil palm expansion in several tropical countries increasingly increasing, especially in Indonesia. The phenomenon of land conversion that occurred in Wajo Regency was caused by the entry of plantation companies which resulted in the shifting of livelihood systems and livelihood strategies. Changing agricultural land into an oil palm plantation area with a partnership system has an impact on the limited community in managing and accessing their land. Farming activities for both rice and other commodities such as cashew and others as well as cattle grazing activities cannot be done on agricultural lands that have been partnered for oil palm plantations. This condition triggered shocks to the farmer's household livelihood system. So that in the process the community carries out various adaptation of livelihood strategies. Therefore, this study aims to analyze the livelihood strategy of the community in meeting household needs before and after the conversion of agricultural land to oil palm plantations. This study uses snowball sampling and in-depth interviews conducted in the village of Taddangpalie, Penrang District. The results showed that the livelihood strategies of farmer households before conversion which had the largest percentage were survival strategies (53%), consolidation (30%), accumulative (17%) with the agricultural basis. After land conversion occurs there is a decrease in the survival strategy phase which is to be (48%) because some households switch the consolidation phase by (40%), and the accumulative phase still remains at the percentage, with the dominant basis being agriculture and non-agriculture. Vulnerability in the form of shock, trend, and equality is overcome by two types of strategies namely survival strategies and consolidation strategies by adopting human capital, social capital, natural capital, and financial capital.

Lahan gambut merupakan komponen ketahanan lingkungan yang diupayakan untuk menjamin keamanan publik dan munculnya bahaya lingkungan yang disebabkan secara alami oleh alam maupun disengaja oleh perbuatan manusia. Lahan gambut di Desa Teluk Empening telah mengalami konversi menjadi lahan usahatani seperti lahan sawit, karet dan jahe, sedangkan lahan sekunder yang ada pada daerah penelitian sebelumnya pernah mengalami kebakaran pada tahun 2017. Penelitian ini dilakukan dengan mengidentifikasi keanekaragaman jenis pada lahan gambut dengan melakukan pengukuran biodiversitas lahan dengan analisis vegetasi. Kemudian menganalisis pengaruh konversi lahan gambut dengan pengukuran sifat fisik tanah, pengukuran Tinggi Muka Air tanah, pengukuran dimensi saluran dan pengujian kualitas air. Perubahan dinamika tutupan lahan yang dipengaruhi oleh kondisi sosial ekonomi masyarakat, data diperoleh dengan menggunakan observasi, wawancara dan kuesioner sebanyak 30 sampel. Hasil analisis menunjukkan lahan jahe, karet dan sawit memiliki nilai indeks keanekaragaman (H’) ±0 dikategorikan biodiversitas rendah. Lahan sekunder memiliki nilai indeks keanekaragaman (H’) 2,001 masuk kategori biodiversitas sedang. Konversi lahan gambut mempengaruhi sifat fisik tanah gambut seperti parameter porositas, permeabilitas, kadar serat dan kadar air. Konversi lahan gambut menjadi lahan karet memengaruhi penurunan muka air tanah yaitu setinggi 68 cm. Pengaruh konversi terhadap kualitas air pada lahan, ditandai dengan parameter pH berkisar 3,3 - 4,6, TSS berkisar 6-440 mg/l dan DO berkisar 0,89-3,4 mg/l yang tidak sesuai dengan baku mutu yang ditetapkan yaitu Kelas 2 PP No.82 Tahun 2001. Konversi lahan gambut semakin meningkat tiap tahun dan mempengaruhi kondisi sosial ekonomi masyarakat dengan fungsi sosial penyerapan tenaga kerja serta fungsi ekonomi pendapatan dari hasil produksi usahatani. Lahan gambut memberikan keunggulan dan kapasitas bagi kawasan lokal untuk kekuatan alam seperti lingkungan, ekonomi dan sosial yang dapat dilakukan sambil tetap menjaga daya tahan lingkungan. AbstractPeatlands are a component of environmental resilience that strives to ensure the safety and security of environmental hazards caused naturally or intentionally by human actions. Peatland in Teluk Empening Village has undergone conversion to agricultural land such as oil palm, rubber and ginger, while the secondary land in the previous study area experienced fires in 2017. This research was conducted by identifying the diversity of species on peatland by measuring biodiversity land with vegetation analysis. Then analyze the effect of peat land conversion with physical measurements of soil, measurement of groundwater level, measurement of channel dimensions and testing of water quality. Changes in land cover dynamics obtained from socio-economic conditions, data obtained using observations, interviews and questionnaires as many as 30 samples. The analysis showed that ginger, rubber and oil palm land had a diversity index value (H ') ± 0 which was categorized as low biodiversity. Secondary land has a diversity index value (H ') of 2,001 in the medium biodiversity category. Peat land conversion affects the physical properties of peat soil such as parameters of porosity, permeability, fiber content and air content. The conversion of peatlands to rubber lands has an effect on the decrease in the water table, which is 68 cm long. The effect of conversion on water quality in land, fear with pH parameters ranging from 3.3 to 4.6, TSS ranging from 6-440 mg / l and DO ranging from 0.89-3.4 mg / l which are not in accordance with the specified quality standards namely Class 2 PP No. 82 Year 2001. Conversion of peatlands is increasing every year and affects the socio-economic conditions of the community with the social function of absorption of labor and the economic function of income from agricultural production. Peatlands provide advantages and capacities for local areas for natural forces such as environment, economy and social that can be done while maintaining environmental resilience.

Abstract. Continuous agricultural land conversion poses threat to food security but this has not been monitored due to ineffectual policies. One of the Philippine provinces with a high rate of conversion is the rice-producing province of Cavite. To assess the spatiotemporal dynamics of agricultural land conversion in Cavite, this study aims to develop an operational methodology to produce Land Use and Land Cover (LULC) change maps using a multi-sensor remote sensing approach for decision making and planning. LULC maps were generated using Random Forest Classification of Landsat 8 and Sentinel-1 image collections. Spectral indices, combinations of radar polarizations (VV, VH), and their principal components were included to improve its accuracy. Conversion maps were generated by taking the bi-annual difference of LULC maps from 2016 to 2019. Accuracy was assessed using visual inspection with Google Earth Pro. Classification was carried out using single-sensor (optical or radar) and multi-sensor (optical and radar) approach in combination with three feature selection algorithms, namely, Sandri and Zuccolotto (2006), Liaw and Wiener (2015), Kursa and Rudnicki (2010). Multi-sensor and single sensor yielded similarly high overall accuracies (OA = 96%) with the exception of single-sensor radar approach (OA = 53%). Multi-sensor approaches exhibit high accuracies (Cumulative Accuracy = 91%) in detecting agricultural to built-up LULC change up to 5,000 square meters unlike single-sensor optical approach (Cumulative Accuracy = 76%). Among the multi-sensor approaches, the method of Liaw and Wiener (2015) remains to be superior as it only uses eight (8) variables.

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.

Uncontrolled urban expansion resulting from urbanization has a disastrous impact on agricultural land. This situation is being experienced by the densely populated and fertile island Java in Indonesia. Remote sensing technologies have developed rapidly in recent years, including the creation of Google Earth Engine (GEE). Intensity analysis (IA) is increasingly being used to systematically and substantially analyze land-use/land-cover (LULC) change. As yet, however, no study of land conversion from agriculture to urban areas in Indonesia has adopted GEE and IA approaches simultaneously. Therefore, this study aims to monitor urban penetration to agricultural land in the north coastal region of West Java Province by applying both methods to two time intervals: 2003–2013 and 2013–2020. Landsat data and a robust random forest (RF) classifier available in GEE were chosen for producing LULC maps. Monitoring LULC change using GEE and IA has demonstrated reliable findings. The overall accuracy of Landsat image classification results for 2003, 2013, and 2020 were 88%, 87%, and 88%, respectively. IA outputs at interval levels for all categories showed that the annual change-of-area rate was higher during 2013–2020 than during 2003–2013. At the category level, IA results showed that the area of agricultural land experienced net losses in both periods, with net loss in 2013–2020 being 2.3 times greater than that in 2003–2013 (∼1,850 ha per year). In contrast, the built-up area made net gains in both periods, reaching almost twice as much in the second period as in the first (∼2,030 ha per year). The transition-level IA performed proved that agricultural land had been the primary target for the expansion of built-up areas. The most extensive spatial distribution of land conversion from agriculture to built-up area was concentrated in the regencies of Bekasi, Karawang, and Cirebon. These findings are intended to provide stakeholders with enrichment in terms of available literature and with valuable inputs useful for identifying better urban and regional planning policies in Indonesia and similar regions.

This study aims to explore information on improving community welfare after converting agricultural land to oil palm land. Many of the villagers carry out land conversion to increase income as a means of fulfilling their daily needs, although in reality not all of them get welfare. The method used in this research is descriptive qualitative. Data mining was carried out by interview and documentation. Interviews were conducted with smallholders who converted land to oil palm, stakeholders and local government. The results of the interview were then triangulated with documentation obtained from library searches in the form of books, articles and previous research. The results of this study indicate an increase in the welfare of the community after land conversion but with very binding rules both from the state and from the prevailing market rules.

The massive expansion of oil palm plantations for the benefit of the palm oil industry and its derivatives has an impact on ecosystem and environmental damage as well as large demands for land conversion that threaten agricultural land for food crops, which also threatens food security on it. Jebus Village, Kumpeh District, Muaro Jambi Regency, Jambi Province which has peat soil type for most of its land, in this case is one of the villages facing the problem of oil palm plantation expansion and land conversion which is starting to threaten agricultural land for food crops. Therefore, the Jebus Village Regulation No.1 of 2017 concerning the Protection of Peatlands for Sustainable Food Crops and Plantations was made to protect food land in Jebus village. This study aims to analyze the implementation of peatland protection for sustainable food crops in Jebus village. This research uses descriptive qualitative methods. The collection of various data is carried out with a combination of in-depth interview and observation techniques and is supported by data from research results or reports. Data processing uses coding to obtain meaning which is presented in narrative form. This study found that the implementation of the Village Regulation was able to reduce the threat of damage to peatlands, restrain the rate of conversion of food agricultural land into plantations that were not environmentally friendly. However, the implementation of this policy has not been able to guarantee the availability of staple food (rice) for the Jebus village community. In addition, policy implementation faces challenges that cannot be resolved at the village scale.

Economic Agglomeration

Urbanization involves expansion of the amount of land covered by urban uses. Rural to urban land conversion (RULC) can satisfy demand for the additional space that growing cities require. However, there can be negative consequences, such as the loss of productive agricultural land and/or the destruction of natural habitats. Considerable interest therefore exists among policy makers and researchers regarding how the efficiency of RULC can be maximized. We used the Gini index and a data envelopment analysis to quantify the relationship between RULC and economic development for 17 metropolitan areas in China. We did this from two perspectives: (i) coordination; and (ii) efficiency. We found that economic agglomeration fosters the coordination of the amount of rural land that is allocated to be converted to urban uses. Similarly, economic agglomeration increases the efficiency of RULC in terms of the processes of socio-economic production. Through production technology innovation and readjustment in the scale of input factors, the productive efficiency of RULC can be promoted. Our findings suggest a need to strictly limit the amount of RULC, design differential land management policies according to location and development level, and adjust RULC allocation between different cities. Further, in harnessing the potential of intensive urban land use and restructuring, production factors, including land, can be enhanced through technological innovation. Research presented in this paper provides insights for areas of the world which are yet to undergo the rapid urbanization that China has experienced, but where it is projected to occur over the coming decades.
