“…In addition, research on the causes of drought in the rubber ecosystem [17] and the mechanisms of drought resistance [9] are considered in depth, and systematic progress has been made. However, there are few findings on the vulnerability of rubber ecosystems to drought [18,19]. The term vulnerability refers to the frangible nature of a system threatened by different disasters [20] with different intensities and duration.…”

Rapidly developing droughts, including flash droughts, have occurred frequently in recent years, causing significant damage to agroforestry ecosystems, and they are expected to increase in the future due to global warming. The artificial forest area in China is the largest in the world, and its carbon budget is crucial to the global carbon sink. As the most prominent plantation plant in the tropics, the rubber (Hevea brasiliensis (Willd. ex A. Juss.) Muell. Arg.) ecosystem not only has important economic significance, but also has the potential to be a major natural carbon sink in hot areas. Frequent drought events have a significant impact on rubber ecosystem productivity, yet there have been few reports on the vulnerability of rubber productivity to drought. The objective of this study is to evaluate the vulnerability of rubber ecosystem gross primary production (GPP) to short-term flash drought (STFD) in Hainan Island, utilizing the localized EC-LUE model (eddy covariance–light use efficiency) validated by flux tower observations as the research tool to conduct the scenario simulations which defined by standard relative humidity index (SRHI), in a total of 96 scenarios (timing × intensity). The results show that, in terms of time, the rubber ecosystem in Hainan Island has the highest vulnerability to STFD during the early rainy season and the lowest at the end of the rainy season. From the dry season to the rainy season, the impact of STFD gradually extends to the northeast. Spatially, the vulnerability of the northern island is higher than that of the southern island and that of the western part is higher than that of eastern Hainan Island. With the increase in STFD intensity, the spatial distribution center of the vulnerability of rubber ecosystem GPP in Hainan Island gradually moves southward. The spatiotemporal pattern of the vulnerability of the rubber ecosystem GPP to STFD over Hainan Island plotted by this study is expected to provide decision makers with more accurate information on the prevention and control of drought disaster risk in rubber ecosystems.

“…The temperature rises, changes in rainfall patterns, high carbon dioxide (CO2) concentration emissions, and extreme climatic events, including droughts, floods, heatwaves, and landslides have all favorable and detrimentally impacted agricultural commodities, creating vulnerability in the food supply. Unfortunately, there are limited previous studies involving Malaysia that have been carried out in modeling the impact of several climates' numerical variables such as temperature [7][8], rainfall amount [7][8], and the occurrence of extreme climatic events such as drought, flood, and sea-level rise [9] towards the agricultural production yields.…”

“…Hazir et al [9] carried out a preliminary study on projecting the effect of drought, flood, and sea-level rise on rubber production yields focusing on Peninsular Malaysia. Their study indicated that the occurrence of these hydrometeorological events may not severely affect rubber production yields in Peninsular Malaysia.…”

The occurrence of climate change is attributable to anthropogenic emissions of greenhouse gases (GHG) which have affected the C3 plants’ agricultural production yields in past decades. Therefore, this article aims to model the linear association among these C3 plants’ agricultural production yields with several climatic and non-climatic explanatory variables using one-way random-effects error components regression model. To be congruent with the main objective of this study, the balanced longitudinal dataset period 1980 to 2018 under big data was acquired. The analysis results revealed that merely maximum temperature (

“…In the case of rubber yield for the first, second and third year after tapping that were experiencing moderate to severe drought conditions, the yield reduced between 43 to 55% compared to the irrigated trees (Devkumar et al, 1998). Additionally, projection on drought frequency for 2024 showed that in the next 3 to 10 years would foresee about 27.6% of rubber planted areas being prone to drought (Mohd Hazir et al, 2018). Thus, screening and evaluation at the immature stage are important measures to gauge the level of adaptation of Hevea clonal seedlings to water stress.…”

Water stress has been identified as one of the most critical environmental factors that will affect crop productivity in the coming years. Since the propagation of Hevea brasiliensis uses the bud-grafting method, selecting a good rootstock is crucial to withstand water stress conditions. This is due to the rootstock scion interaction accounting for about 20% contribution to the scion growth. In this study, four Hevea clonal seedlings namely RRIM 2002, RRIM 2020, RRIM 2023 and RRIM 2024, were observed for their intrinsic tolerance to water stress conditions. Two to three whorls of plants in polybags were grown in the glasshouse and subjected to two water treatments which were well-watered and water stress by withholding irrigation for 14 days. Physiological traits (chlorophyll pigments, membrane stability and epicuticular wax content), relative water content, and proline and sucrose contents were observed. After commencing the water stress condition for 14 days, all four clonal seedlings showed significantly decreased leaf relative water content. In addition, variation was discerned in leaf cell membrane stability that coincided with significantly lower membrane injury. An increasing trend in proline content from day seven to 14 and a comparable sucrose content in leaf tissue throughout the experiment were also observed. RRIM 2023 exhibited the highest membrane stability, whilst RRIM 2020 was severely affected, which reflected on their low ability to withstand water stress. A similar trend was observed for epicuticular wax content, chlorophyll b and total chlorophyll of RRIM 2023 compared to RRIM 2020. Hence, membrane stability supported by epicuticular wax content and chlorophyll levels revealed RRIM 2023 as the most resilient to water stress.
