“…The majority of very high levels of risk are in the maintenance stage, both the vegetative and the generative phase (growth, flowering and fertilization). Wind and rain during flowering can reduce rice production [12] the generative phase has the highest total RPN according to reference [13] The generative phase of rice is more susceptible to rain than the vegetative phase. The recommended recommendation in managing this risk is to transfer risk.…”

Climatic conditions continue to change, can be seen from various parameters such as rainfall, rainy days, wind speed and solar irradiation. Theoretically, it has an impact on the productivity and welfare of rice farmers and also poses a risk to production and directly or indirectly impacts the finances of rice farmers. The aims of this study were to analyze whether there are differences in rice farming productivity under different climatic conditions. Then to analyze the financial risk on farming rice due the climate change. The research location is in Hamparan Perak District, Deli Serdang Regency, Sumatra Utara Province. We involved 50 farmers as samples and three experts and experienced farmers in risk analysis. Analysis of productivity differences was carried out using the paired sample t-test method with the SPSS 26 tool. While risk analysis is carried out using failure mode effect analysis with Risk Priority Number calculation techniques. The results found that there were significant differences in rice farming productivity during planting periods with different climates. There are 22 financial risks that have the potential to occur in the rice farming process, from land preparation to harvesting stage. The highest level of risk is at the maintenance stage.

“…The lack of a relationship between typhoon wind speed and rice is possibly due to the stronger cyclones missing the vulnerable growing and harvesting periods for rice. Rice plants were the most vulnerable to wind speeds of between 8 and 70 km/h at the heading stage and 14-30 days after heading [5], and it was possible that most typhoons may have occurred when the rice plants were less prone to wind damage.…”

“…Crops like bananas, pomelos, and papayas are vulnerable to strong winds as fruits and branches are easily blown off, while the roots and leaves of melon crops and leafy vegetables are easily damaged by flooding and storm surges [4]. The growth stage of the plant is also another critical factor that may affect the extent of crop damage [4][5][6]. Rice plants at the heading stage are particularly prone to lodging induced by excessive wind and the weight of water on the canopy from the rain associated with a typhoon.…”

Typhoons are destructive multi-hazard events. To assess the relationship between typhoon intensity and agricultural loss, there is a need for accurate and standardized information on loss and damage, which is currently lacking. To address this, a database for Vietnam and the Philippines was created to provide aggregated information on the magnitude of rice damage and to highlight the rice-growing areas which were prone to being damaged by typhoons. Our study period was from 1970 to 2018, and we focused on Vietnam and the Philippines as these two countries experience frequent and intense typhoons. As different crops respond differently to wind and rain, we limit our research to a single crop. In this study, we focused on rice as it is a major staple food in Southeast Asia, and rice fields were often damaged by typhoons in the two countries. Of the 829 typhoon events recorded, only 15% of the events resulted in rice damage. The average area of rice damaged per typhoon event ranged from 42,407 ha in Vietnam to 83,571 ha in the Philippines. Meanwhile, the average production loss per typhoon event ranged from 190,227 metric tonnes in the Philippines to 539,150 metric tonnes in Vietnam. The monetary value of rice crops lost was only reported in the Philippines, and this amounted to an average of US$ 42 million per typhoon event. There was a weak relationship between landfall wind speed and the three indicators of rice damage, which suggests that rice damage was not primarily due to strong winds. Our results showed that the rice fields in the coastal provinces of Vietnam and the northern parts of the Philippines were more vulnerable to being damaged by typhoons.

“…This value is an indication of a strong relationship between rainfall and rice production, or, alternatively, a decrease in rice production as a result of an increase in rainfall. A study by [32] showed that high precipitation affected panicle filling and increased the number of unfilled grains. Although rainfall is beneficial in terms of increase in water availability, excessive amount of rainfall will be an abiotic stress on rice plants.…”

“…With a correlation value of 0.75, the results of the Pearson correlation analysis show that the vulnerability ratio has a significant impact on production. Based on the Seemingly Unrelated Regression (SUR) analysis conducted by [32], it was found that West Java Province was the area most affected by climate change. This result also supports a recent study conducted by [38], which found that agricultural intensification through mechanisation is a strategy to mitigate climate change, although it is still implemented by few farmers.…”

Climate change threatens the sustainability of the agricultural sector and has the potential to affect food availability in West Java, Indonesia’s rice production centre. This study aims to examine how agricultural infrastructure has developed over the past five years and how this has affected the vulnerability index. Climate, production, agricultural infrastructure and facilities data were collected from various sources, including the Central Statistics Agency, the Ministry of Agriculture, and the Directorate General of Agricultural Infrastructure and Facilities. The data were analysed to obtain Pearson correlation values and vulnerability levels based on the ratio of production inputs to harvested area. The results show that climatic elements affect rice production in West Java, especially rainfall (r = 0.82), which is negatively correlated with production. The increase in rainfall causes significant flooding, which leads to crop failure. Production inputs such as agricultural machinery, ponds and rehabilitated tertiary irrigation networks (RTIN) support production and mitigate climate impacts. Rice production has a high Pearson correlation with the vulnerability index (r =0.75). The vulnerability ratio for West Java in 2022 was 0.0015, which means it is classified as vulnerable.
