Land is the main resource in carrying out development. Reduction of land area, especially agricultural land for development also has an impact on the area of agricultural land in Bali, especially in Badung Regency. The construction of accommodation to support the tourism sector led to the conversion of agricultural land in Badung Regency, which is mostly found in South Badung. North Badung, which does not have as many attractions as those in South Badung, has in fact also experienced the conversion of agricultural land, especially rice fields, as was the case in the Abiansemal and Mengwi Sub-Districts. The purpose of this study is to determine the factors that cause the conversion of paddy fields in the North Badung sub-district and determine the strategy to control the conversion of wetland in North Badung. The technique for determining key informants was done by purposive sampling with a total of 20 people. The analysis technique used is the Interpretive Structural Modeling (ISM) analysis. The results showed that the factors that caused the conversion of paddy fields or wetland in North Badung were economic elements, namely rice farming income, harvest price stability, access to crop marketing and paddy land prices. Social elements, namely family participation in managing rice fields, the influence of modernization on agriculture, the number of family members who are covered and regeneration of rice field management. The third elements is the environment, namely the level of water irrigation of rice fields, pests and diseases and housing needs due to increasing population. The strategy of controlling wetland conversion in North Badung that can be done based on short-term management priorities in the independent sector is the Millennial Farmer program.

Abstract. Nitrous oxide (N2O) is a long-lived greenhouse gas with a large radiation intensity and it is emitted mainly from agricultural land. Accurate estimates of total direct N2O emissions from croplands on a country scale are important for global budgets of anthropogenic sources of N2O emissions and for the development of effective mitigation strategies. The objectives of this study were to re-estimate direct N2O emissions using localized emission factors and a database of measurements from Chinese croplands. We obtained N2O emission factors for paddy fields (0.41 ± 0.04%) and uplands (1.05 ± 0.02%) from a normalization process through cube root transformation of the original data. After comparing the results of normalization from the original values, Logarithmic and cube root transformations were used because the frequency of the original data was not normally distributed. Direct N2O emissions from Chinese croplands from 1980 to 2007 were estimated using IPCC (2006) guidelines combined with separate localized emission factors for paddy fields and upland areas. Direct N2O emissions from paddy fields showed little change, increasing by 10.5% with an annual rate of increase of 0.4% from 32.3 Gg N2O-N in 1980 to 35.7 Gg N2O-N in 2007. In contrast, emissions from uplands changed dramatically, increasing by 308% with an annual rate of 11% from 68.0 Gg N2O-N in 1980 to 278 Gg N2O-N in 2007. Total direct N2O emissions from Chinese croplands increased by 213% with an annual rate of 7.6% from 100 Gg N2O-N in 1980 to 313 Gg N2O-N in 2007, and were determined mainly by upland emissions (accounting for 67.8–88.6% of total emissions from 1980 to 2007). Synthetic N fertilizers played a major role in N2O emissions from agricultural land, and the magnitude of the contributions to total direct N2O emissions made by different amendments was synthetic N fertilizer > manure > straw, representing about 78, 15, and 6% of total direct N2O emissions, respectively, between 2000 and 2007. The spatial pattern of total N2O emissions in 2007 in China shows that high direct N2O emissions occurred mainly in the north and in the Sichuan Basin in the southwest. The provinces with the highest emissions were Henan (35.4 Gg) and Shandong (31.6 Gg) and Tibet had the lowest (0.65 Gg). High direct N2O emissions per unit of arable land occurred mainly on the North China Plain and the southeast coast. The mean value nationally was 2.52 kg N ha−1, with 18 provinces above this value and with emissions of >4.0 kg N ha−1 in Beijing, Tianjin and in Jiangsu, Shandong, Fujian and Henan provinces.

Suburban Developments

Denpasar City as the capital of Bali Province is attractive to regional development. The limited space of Denpasar City directs the development towards the periphery. The extension of physical urban form will be a significant factor of suburban developments. The study aims to examine the type of urban sprawl development in the Denpasar suburbs, and their relation to the existence of agriculture. The qualitative research method is used to analyze the type of urban sprawl with the following indicators of typical land uses covering rice fields, forest park, open land, and settlements. Remote sensing analysis of these four indicators applies GIS model drawn from three time-series data of 2005, 2010 and 2015. Spatial approaches are applied to examine the patterns and structures of urban sprawl types. The results find two main types of urban sprawl development in the city suburbs, that is, leapfrog type which is mostly scattered in the north, and the ribbon type mainly centered in the eastern part of Denpasar City. Both types of urban sprawl play a crucial role in decreasing the amount of agricultural land, especially rice fields, in the suburbs of Denpasar.

Conversion of agricultural land to non-agriculture is an unavoidable phenomenon, therefore efforts are needed to regulate land use. The purpose of this study is to analyze the rate of conversion of paddy fields by identifying patterns and spatial changes in land and the factors that influence it, as well as analyzing the suitability and availability of lowland rice fields and the suitability of existing lowland rice fields with spatial pattern plans. The study used primary data in the form of semi-detailed soil maps, and secondary data in the form of supporting data and reports. The analytical tools used are Geographic Information Systems, and binary logistic regression. Based on the results of the analysis, it shows that the overall pattern of land use change is 26 patterns of change with a total change area of 127,154 ha (25.81 %), where the area of rice fields is reduced by 1,241 ha in the period 2010-2018. The locational rent factor that has the greatest chance of causing rice field conversion is the distance to the center of the kelurahan/village with a negative coefficient (-3.25461631). The most dominant actual land suitability for existing lowland rice is S1 (74.58%) then S3rf (13.86%) and S3r (10.83%), S3e (0.55%). Evaluation of the alignment of the actual land suitability of the existing rice fields with the spatial pattern plan obtained in the aligned category (67.65%) and potentially aligned (28.16%) with the proposed recommendation that existing rice fields can be one of the considerations for sustainable food land allocation by carrying out strict control on the conversion of paddy fields as well as increasing management efforts to obtain more optimal rice production results and as a material for consideration in reviewing the spatial planing in the RTRW.

Agricultural land conversion (ALC) is economically profitable, but what the community does not pay attention to is the losses caused by the ALC. Economic valuation is one way to calculate the multifunctionality of paddy fields that have overall economic value, including the production function, provider of environmental products/services and socio-culture. This study aims at determining the economic value of paddy fields as employment services providers for farmers. The analytical method employed was the economic valuation. Research result: It shows that the conversion of paddy fields in Pasuruan Regency in 2014-2019 is quite high, averaging 777.7 Ha per year. The economic value of rice fields as an employment services provider in 2019 is IDR 1,922,772,319,000. This value tends to decline due to land conversion since 2014.

Negative Impacts

Unlicensed gold mining (PETI) is rife in the community, especially entrepreneurs / capital owners since the last ten years in Merangin Regency. Lack of awareness of negative impacts is a problem that needs serious attention from the government. There are miners who come from outside and from the community itself. Even though PETI is difficult to overcome, many of the people who own the land have processed it to be planted with rice again. In other places or areas in Indonesia, many ex-PETI lands cannot be planted with rice anymore because they have already contaminated with mercury. Due to the fact that many ex-PETI lands have been re-processed into paddy fields in Merangin Regency, a research was conducted which took place in Pangkalan Jambu District. The reason for choosing Pangkalan Jambu sub-district as the research location is because in this sub-district the largest area of ​​land in Merangin Regency is being mined by the community. The research was conducted with a case study qualitative approach with data collection techniques, observation, interviews and documentation. The purpose of this study was to examine the processing of ex-PETI rice fields into reclamation. The results of the study concluded that the reclamation activity was carried out after several landowners tried to plant rice on the ex-PETI land which was successful and did not encounter any significant obstacles. Starting from here, other residents did the same thing and it turns out that it continues to grow until now. As the reason why rice plants can thrive, it turns out that in this place the miners do not use mercury when mining. Previously, the area of productive rice fields was 1202 ha and now, of the eight villages, the number of rice fields that have been reproducing (reclaimed) is 139 ha. There are 804 ha of rice fields damaged by PETI and there are 259 ha of land that are not damaged but have not yet operated or have not recovered and need to be reclaimed again.

In general, the development of agricultural land usage change was illustrated through linear trend analysis without comparing it first with other trend analysis. As a consequence, it was assumed that the data will be in a straight line with a tendency for constant numbers over a period of time. However, the facts on the ground proved that the area of ??agricultural land converted into non-agricultural land was not always the same from year to year. The novelty of this research was to do a comparison between linear and non-linear trends to predict the development of rice fields, so that an accurate forecasting model was obtained. The aim of this research were: 1) knowing the development of rice fields area in the Special Region of Yogyakarta, 2) determining the appropriate forecasting model for the development of rice fields area in the Special Region of Yogyakarta, and 3) forecasting the area of ??rice fields in the Special Region of Yogyakarta. The data that used came from BPS (Central Bureau of Statistics) from 1996 to 2017. The trend models being compared were linear trends, quadratic trends, and exponential trends. The results showed that the area of ??rice fields in the Special Region of Yogyakarta tended to decrease from year to year. The best forecasting model was an exponential trend. In 2017 to 2021, it was estimated that there will be a decrease in rice field area of ??221 hectares or 0.41 percent per year.

National Food Security

The availability of agricultural land, especially paddy fields, is an inseparable part of efforts to maintain national food security and engage SDGs’ second goal. Changes in land cover/land use can occur due to social, political, economic, cultural, natural, and technological factors. Geographic Information Systems (GIS) operate as a tool to comprehend the changes related to the driver’s factors. The purpose of this study was to examine the spatial dynamics of paddy land cover in the Banyuasin Regency for more than 2 decades using the Markov Chain approach and to analyze the inhibiting and supporting factors in developing paddy farming in the region. The inhibiting factor discussed in this study is the potentiality of floods in paddy fields. The results showed that paddy fields in Banyuasin Regency experienced the widest decrease of 2,863.80 hectares and encountered the largest increase of 14,463.45 hectares in 1990-2003. The threat factor also influenced changes in the area of agricultural land in the form of inundation. The flood inundation crisis peaked in 2010, where 832.58 hectares out of 164,562.37 hectares of paddy field were flooded. However, the potency in developing lowland rice farming on swamps in Banyuasin Regency is considerably beneficial. This can be examined from the value of Revenue-Cost Ratio (R/C Ratio), averaging 3.65, and BenefitCost Ratio (B/C Ratio) of 2.65 with an average production of 5-7 tons/hectares/season.
