“…Karawang was regionally divided into two major landscapes: lowland and coastal areas on the northern part with elevations ranging from 0 to 50 m and a hilly area on the southern part with elevation from 50 to 1,291 m above mean sea level. [8] stated that Up 95% of low land areas which classified as the S1 category (very suitable) for planting the paddy…”

“…Such heterogeneous landscapes of Karawang included 11 land use classes and three land cover classes based on the (SN176 451:2014) Indonesian National Standard. Yet, due to the difficulties in identifying some classes by a medium-resolution image of Landsat, they categorized all classes into seven land use classes based on this previous study [8]. The identified classes were 1) Forests, 2) Open Water Bodies, 3) Build-up Areas, 4) Fishponds, 5) Drylands/mixed gardens, 6) Bare lands, and 7) Paddy fields (Table 2).…”

“…The regency experienced massive land-use change over the land for three decades. Its lost 18460.8 ha of its paddy farmlands between 1994 -2015 [8]. The regency paddy farmlands had been reduced from 120,371 ha in 2000 to 98.462 ha in 2015, and it's projected to be just 95.556 ha in 2031 [9] [10].…”

Paddy fields are the most crucial agricultural land-use in Indonesia that supporting national food security. Such lands have been experienced a massive change in their dynamics, specifically in rice production home, West Java. Karawang paddy fields notably become the major victim of land-use change along with rapid economic growth, development, and population pressure. This study aimed to assess paddy fields’ conversion dynamic and how land-use change contributes to this issue in Karawang. Remote sensing techniques and satellite images were used for investigation across the Karawang Regency. Three kinds of satellite image datasets of Landsat 5 TM, Landsat 8 OLI, and Sentinel 2 during the periods of 2009, 2014, and 2019 were analyzed. The results revealed that land-use change impacted paddy fields conversion significantly. Karawang regency lost 16346.77 ha or 8.54 % of its paddy fields throughout the study period. Such farmlands declined by 8639.84 ha (4.51%) and 7706.93 ha (4.02%) between 2009 -2014 and 2014 to 2019, respectively. The conversion of paddy fields to build areas, including road infrastructures, is approximately 14536.21 ha, representing 57.98% of the total paddy fields converted. It concluded that paddy fields had faced massive conversion over the last ten years driven by conversion into buildup areas due to the increased land demand, i.e., residential, commercial, and industrial activities.

“…Agriculture area conversion phenomenon in Indonesia has progressively become a matter of concern over the time and it is expected to be a major threat for the sustainability of food production in the future (Franjaya et al, 2017; Utami and Ahamed, 2018). In this respect, government has decided to address the issue with the enactment of Presidential Regulation Number 59 Year 2019, which consists an instruction of land conversion control by provisioning detailed spatial data related to paddy field area in Indonesia.…”

Coastal inundation that is getting farther inland year by year has given a serious problem to the sustainability of farming activities in Pekalongan, but it has rarely been exposed more detail to the public. The aim of this research is to investigate the present effects of seawater inundation to the agriculture sector in Pekalongan coastal area. We focused on the study of coastal inundation dynamics, agriculture area reduction and rice production. Time series remote sensing imageries from google earth satellite were used to analyze the seawater run up between 2003 and 2018. This result revealed that the farthest distance of the inundation in 2018 reached 4.4 kilometers from the coastline in the west part of the city. For the last fifteen years, saline water has reduced almost 380 ha of farm land in the coastal area. That phenomenon has contributed to the rice production lost by almost 173 tons/year during 2003 and 2018. This result has showed a critical condition of agriculture sector in study area, thus some mitigation actions become a necessity thing in order to protect our land as well as food security on the next future.

“…However, up 25% of regency agricultural land use has been converted to residential, commercial, or industrial use to meet the increasing land demand due to massive urbanization [6]. Karawang lost 18,460.8 ha of its PFs between 1994 and 2015 [7]. On the other hand, the Regency population has increased by 10.76% between 2010 -2019, representing an average growth of 1.19% per year [8][9][10].…”

Paddy field conversions (PFCs) in Indonesia have become a major threat facing agricultural lands on the local, province, and national levels causing a reduction in rice production and leading to food insecurity. Hence, information on the impacts of PFCs on rice supply is crucial for future policy planning and management. This paper aimed to simulate four policy scenarios to view the impact of paddy fields' conversion on rice production to enhance the planning of future food security-related policies. Based on system dynamics modelling (SDM), the study used primary and secondary data to develop a quantitative Stock Flow Diagram from the qualitative Causal Loop Diagram. Available historical data; paddy cultivated area, population, and harvested areas have been used to test and validate the SDM. The study indicated that the overall maximum relative errors, coefficient of determination, and mean absolute error of tested variables were 1.33%, 0.760, and 1.49, respectively. Under the Business-as-usual scenario, it was found that the population of Karawang will reach 6.1 million people, and the paddy fields will be reduced to only 169 thousand ha by the end of the century. Thus, Karawang rice Availability Per Person, Surplus, and Self-sufficiency will be reduced by 66.20, 50.55, and 359%, respectively. Consequently, the obligation of 1.5 million tons a year cannot be met. Besides that, the Rice demand scenario indicated the Regency will be out of rice surplus in 2094 and 2085 when the demand for rice increases by 80% (SNO#3.3) and 100% (SNO#3.4), respectively. It's been concluded that paddy field conversion is the main threat that may undermine future rice production for Regency. The study recommended that proposed possible interventions should be considered along with formulating and implementing upcoming Regional Short, Medium, and long-term Development Plans.
