“…In respect to spatial scales in agricultural research, small plots usually serve to test separate agronomic practices and the farm is often used as a research entity to consider management decisions from different perspectives (e.g., Ref. [ 43 ]), e.g., for the evaluation of nitrogen dynamics and balances [ 44 , 45 ]. Such approaches, however, miss spatio-temporal changes and further environmental consequences at a larger scale [ 41 ].…”

“…The salinity intrusion into cultivated land has threatened food production mainly because it reduces the available harvested area (Takama et al 2021). Another study also indicates that the impact of salinity in several countries causes the loss of agricultural land and has created risks and uncertainties to agricultural activities (Dam et al 2019a). In general, decreased growth due to salinity in the short term affects osmosis because of lower water availability.…”

Climate change has negatively affected agricultural productivity in Indonesia. This study aimed to conduct a bibliometric analysis of the literature on soil salinity caused by climate change, discuss the impact of soil salinity on Indonesian agriculture, examine various strategies for adaptation to salinity, and deliver some ideas for future research. An analysis of 39 identified Scopus articles related to farmers' vulnerability, adaptation, and practices was carried out. This study was performed in November 2022 and employed Bibliometrix R-package and VOSviewer software. Findings show that salinity has left Indonesia's agriculture vulnerable to reduced food production, especially for small-scale farmers losing crop yields and land. Various adaptation measures have been initiated, such as restoring soil fertility and using saline-resistant varieties. Irrigation facilities improvements have also been carried out to reduce the risks of soil salinity expansion. Farmers also try social action measures, such as selling assets, borrowing money for daily needs, and even changing jobs. However, farmers to survive and sustain their businesses, any any such measures need to produce satisfactory results. A review of the existing literature reveals a lack of soil salinity studies in Indonesia which simultaneously points to research gaps not only on the issue of the impact of salinity on income and the vulnerability of small farmers but also on the development of adaptation strategies to address salinity due to climate change.

“…According to Takehisa et al (2004) almost 30% of the world's paddy cultivation area is affected by salinity and 50% of paddy production reduced because of saline water (Ma et al, 2018). As the second largest of world rice exporter, Vietnam faced the problem of the sea level rise which had a significant impact on rice production (Dam, Amjath-Babu, Bellingrath-Kimura, & Zander, 2019). This phenomenon causes seawater penetration to occur more frequently and loss of the paddy growing land (Dam et al, 2019;Smajgl et al, 2015).…”

Water salinity variability mapping for flooded paddy plots at Kuala Kedah, Malaysia

Salinity is an essential parameter in rice cultivation activity. It has a significant impact on paddy growth and also the yield of paddy. However, the level of salinity concentration in paddy plots depends on the surrounding conditions. The distance of the paddy area from the coastline, the temperature and intensity of rainfall should be considered in studies involving water quality. Additionally, the tide of events is also included in this study because of the position of the study area near the coastline. Therefore, this study was conducted to assess the level of salinity in two different rice cultivation seasons and describe the level of salinity concentration using a salinity variability map using the Inverse Distance Weighted (IDW) interpolation method. The data collection activities involved water sampling at 44 water inlets for each paddy plot in 30 hectares of the study area by referring to the Day After Sowing (DAS) as the paddy's growth stage. These water samples were collected on 10 DAS, 40 DAS, and 60 DAS and subsequently tested using a portable conductivity meter namely EC500 Exstick II pH/Conductivity/Temperature Meter. Parallelly, georeference data which is latitude, longitude and elevation were gathered using Garmin GPSMAP 64s. Then, these data were analyzed using the IDW interpolation method in ArcGIS software and comes with salinity variability maps. The produced maps give an overview of the salinity concentration distribution by color scale range. Based on these salinity variability maps, the highest salinity concentration was recorded on 10 DAS and 60 DAS during Season 1 2019 and Season 2 2019, respectively for both tidal events. This result shows that the salinity concentration trend for both seasons is different due to the amount of rainfall received and the position of the paddy plot compared to the mean temperature factor.
