Culture and Faith: Timbulsloko Community Adaptation and Strategy in Facing Tidal Flood Disaster
2025
Resilience reflects the ability to adapt effectively to challenges, constraints, and pressures. The community in Timbulsloko hamlet faces unique hardships, as daily life must be conducted on waterlogged land, including a submerged cemetery area. Understanding resilience in this context requires exploring not only infrastructural aspects but also the cultural and religious elements that support the community’s endurance in such challenging conditions. This study employs a qualitative approach to capture the dimensions of community resilience in Timbulsloko. Data was gathered through observation, in-depth interviews, and document analysis to provide a comprehensive view of community adaptation. The findings reveal that local cultural practices, such as the tradition of “punggahan,” along with religious gatherings like arwah jama’, manaqiban, and other rituals, are pivotal in fostering a sense of stability and community spirit. These activities help residents maintain resilience and make decisions to stay or adapt despite environmental challenges. This study illustrates that cultural and religious practices function as social capital, strengthening community resilience and supporting collective survival amidst adversity.

Climate change shifts forward flowering and reduces crop waterlogging stress
2021
Climate change will drive increased frequencies of extreme climatic events. Despite this, there is little scholarly information on the extent to which waterlogging caused by extreme rainfall events will impact on crop physiological behaviour. To improve the ability to reliably model crop growth and development under soil waterlogging stress, we advanced the process-basis of waterlogging in the farming systems model Agricultural Systems Production Systems sIMulator. Our new mathematical description of waterlogging adequately represented waterlogging stress effects on the development, biomass and grain yield of many commercial Australian barley genotypes. We then used the improved model to examine how optimal flowering periods (OFPs, the point at which long-term abiotic stresses are minimal) change under historical and future climates in waterlogging-prone environments, and found that climate change will reduce waterlogging stress and shift forward OFP (26 d earlier on average across locations). For the emissions scenario representative concentration pathway 8.5 at 2090, waterlogging stresses diminished but this was not enough to prevent substantial yield reduction due to increasingly severe high temperature stress (−35% average reduction in yield across locations, genotypes and sowing dates). It was shown that seasonal waterlogging stress patterns under future conditions will be similar to those occurring historically. Yield reduction caused by waterlogging stress was 6% and 4% on average across sites under historical and future climates. To adapt, both genotypic and management adaptations will be required: earlier sowing and planting waterlogging tolerant genotypes mitigate yield penalty caused by waterlogging by up to 26% and 24% under historical and future climates. We conclude that even though the prevalence of waterlogging in future will diminish, climate change and extreme climatic events will have substantial and perverse effects on the productivity and sustainability of Australian farms.

Waterlogging is a major abiotic stress affecting plant growth and productivity. Regardless of rainfall or irrigated environments, plants frequently face waterlogging, which may range from short-term to prolonged durations. Excessive precipitation and soil moisture disrupt crop growth, not because of the water itself but due to oxygen deficiency caused by water saturation. This lack of oxygen triggers a cascade of detrimental effects. Once the soil becomes saturated, oxygen depletion leads to anaerobic respiration in plant roots, weakening their respiratory processes. Waterlogging impacts plant morphology, growth, and metabolism, often increasing ethylene production and impairing vital physiological functions. Plants respond to waterlogging stress by altering their morphological structures, energy metabolism, hormone synthesis, and signal transduction pathways. This paper synthesizes findings from previous studies to systematically analyze the effects of waterlogging on plant yield, hormone regulation, signal transduction, and adaptive responses while exploring the mechanisms underlying plant tolerance to waterlogging. For instance, waterlogging reduces crop yield and disrupts key physiological and biochemical processes, such as hormone synthesis and nutrient absorption, leading to deficiencies of essential nutrients like potassium and calcium. Under waterlogged conditions, plants exhibit morphological changes, including the formation of adventitious roots and the development of aeration tissues to enhance oxygen transport. This review also highlighted effective strategies to improve plant tolerance to waterlogging. Examples include strengthening field management practices, applying exogenous hormones such as 6-benzylaminopurine (6-BA) and γ-aminobutyric acid (GABA), overexpressing specific genes (e.g.,
,
, and
), and modifying root architecture. Lastly, we discuss future challenges and propose directions for advancing research in this field.

Differential impacts of soil salinity and water logging on Eucalyptus growth and carbon sequestration under mulched vs. unmulched soils in south-western Punjab, India
2023
Aims To study the impact of salinity and water logging on Eucalyptus growth, carbon (C) sequestration in tree biomass and organic C pool under mulched and unmulched ridges.MethodsWe studied the performance of five Eucalyptus clones viz. C-413, C-2135, C-7, PE-8 and PE-11 on mulched and unmulched ridges, their impact on C sequestration in tree biomass and soil organic C pool, and soil properties.ResultsElectrical conductivity (E.C.) of soil under mulched ridges (3.54 ± 0.3 dS m−1) was decreased by ~ 3.9-times, compared with the unmulched ridges (13.9 ± 0.3 dS m−1) due to Eucalyptus plantation. Tree survival rate on mulched ridges was ~ 78.1%, while on unmulched ridges was ~ 63.4%; C-7 clone had the lowest (~ 55.0%), while the PE-8 had significantly (p < 0.05) higher (~ 89.5%) survival rate. Mulching increased the tree girth (~ 8.7%), height (~ 13.8%), timber wood (~ 18.4%), branches (~ 21.8%), twigs + leaves (~ 22.6%) and root biomass (~ 34.6%) after one year of plantation, compared with their plantation on unmulched ridges. Regardless of the plantation method, C-2135 clone had the lowest, while the PE-11 had the highest timber dry biomass, branches, twigs + leaves and root biomass. After 4-years of plantation, trees planted on mulched ridges had significantly higher C sequestration in timber dry biomass by 147.8 ± 18.4 Mg C ha−1 than those on unmulched ridges.ConclusionsEucalyptus plantation offers a low cost strategy for C sequestration in waterlogged saline soils. Plastic mulching has overwhelming significance in enhancing tree survival rate and decreasing soil salinity with co-benefits of increased biomass productivity of Eucalyptus.

The aim of this paper is to analyse changes in the physicochemical elements in groundwater in the vicinity of a small municipal solid waste landfill site located within the territory of the European Union on the basis of 7-year hydrochemical research. Samples of groundwater and leachate near the examined landfill were collected four times a year during two periods, between 2008 and 2012 during the use of the landfill and between 2013 and 2014 at the stage of its closure. The research results were analysed on the basis of general physicochemical properties: pH; total organic carbon (TOC); electrical conductivity (EC); inorganic elements: Cr, Zn, Cd, Cu, Pb, Hg; and one organic element—polycyclic aromatic hydrocarbon (PAH). The analysis was carried out in accordance with the EU and national legislation requirements regarding landfill monitoring. The assessment of the groundwater and analysis indicators of the leachate pollution allowed interpretation of the impact of the municipal solid waste landfill on the state of the water environment in the immediate vicinity
.
The results show that the increased values of Cd, EC, and TOC turned out to be the determinants of the negative impact of leachate on the groundwater quality below the landfill. The integrated water threat model determined the potential negative impact of a landfill site. The extent depended on local environmental conditions and the self-cleaning process. Deterioration of the chemical status in the quality of the groundwater within the landfill area was a consequence of the lack of efficiency of the existing drainage system, which may result from the 19-year period of its use. The applied correlation relationship between physicochemical elements between leachate and groundwater with a time shift due to the extended time of migration of contaminants or mass transfer in waterlogged ground can be an important tool to identify the threat of groundwater pollution in the area of landfill sites.

agro-ecological responses
2024
Sustainable food security and safety are major concerns on a global scale, especially in developed nations. Adverse agroclimatic conditions affect the largest agricultural-producing areas, which reduces the production of crops. Achieving sustainable food safety is challenging because of several factors, such as soil flooding/waterlogging, ultraviolet (UV) rays, acidic/sodic soil, hazardous ions, low and high temperatures, and nutritional imbalances. Plant growth-promoting rhizobacteria (PGPR) are widely employed in in-vitro conditions because they are widely recognized as a more environmentally and sustainably friendly approach to increasing crop yield in contaminated and fertile soil. Conversely, the use of nanoparticles (NPs) as an amendment in the soil has recently been proposed as an economical way to enhance the texture of the soil and improving agricultural yields. Nowadays, various research experiments have combined or individually applied with the PGPR and NPs for balancing soil elements and crop yield in response to control and adverse situations, with the expectation that both additives might perform well together. According to several research findings, interactive applications significantly increase sustainable crop yields more than PGPR or NPs alone. The present review summarized the functional and mechanistic basis of the interactive role of PGPR and NPs. However, this article focused on the potential of the research direction to realize the possible interaction of PGPR and NPs at a large scale in the upcoming years.

• Low oxygen availability often is associated with soil waterlogging or submergence, but may occur also as hypoxic niches in otherwise aerobic tissues. Experimental evidence assigns a role in Botrytis cinerea resistance to a group of oxygen-unstable Ethylene Response Factors (ERF-VII). Given that infection by B. cinerea often occurs in aerobic organs such as leaves, where ERF-VII stability should be compromised, we explored the possibility of local leaf hypoxia at the site of infection.
• We analyzed the expression of hypoxia-responsive genes in infected leaves. Confocal microscopy was utilized to verify the localization of the ERF-VII protein RAP2.12. Oxygen concentration was measured to evaluate the availability of oxygen (O₂).
• We discovered that infection by B. cinerea induces increased respiration, leading to a drastic drop in the O₂ concentration in an otherwise fully aerobic leaf. The establishment of a local hypoxic area results in stabilization and nuclear relocalization of RAP2.12. The possible roles of defence elicitors, ABA and ethylene were evaluated.
• Local hypoxia at the site of B. cinerea infection allows the stabilization of ERF-VII proteins. Hypoxia at the site of pathogen infection generates a nearly O₂-free environment that may affect the stability of other N-degron-regulated proteins as well as the metabolism of elicitors.

Root Cortex Provides a Venue for Gas-Space Formation and Is Essential for Plant Adaptation to Waterlogging
2019
Lysigenous aerenchyma, which develops by death and subsequent lysis of the cortical cells in roots, is essential for internal long-distance oxygen transport from shoot base to root tips of plants in waterlogged soil. Although many studies focus on the amounts of aerenchyma in roots, significance of the size of the root cortex in which aerenchyma forms has received less research attention. In the present study, we evaluated the cross-sectional area of each root tissue in adventitious roots of upland crops, wheat (
) and maize (
ssp.
), and the wetland crop, rice (
) under aerated or stagnant deoxygenated conditions; the latter can mimic the changes in gas composition in waterlogged soils. Our analyses revealed that the areas of whole root and cortex of the three species increased under stagnant conditions. In rice roots, cortex to stele ratio (CSR) and aerenchyma to cortex ratio (ACR), which is associated with the areas of gas spaces, were much higher than those in wheat and maize roots, suggesting that these anatomical features are essential for a high capacity for oxygen transport along roots. To test this hypothesis, rates of radial oxygen loss (ROL), which is the diffusive flux of oxygen from within a root to the external medium, from thick and thin adventitious roots of rice were measured using a cylindrical (root-sleeving) oxygen electrode, for plants with shoots in air and roots in an oxygen-free medium. As expected, the rate of ROL from thick roots, which have larger cortex and aerenchyma areas, was higher than that of thin roots. The rate of ROL was highest at the apical part of rice roots, where aerenchyma was hardly detected, but at which cuboidal cell arrangement in the cortex provides tissue porosity. We conclude that high CSR in combination with large root diameter is a feature which promotes oxygen transport from shoot base to root tips of plants. Moreover, we propose that CSR should be a useful quantitative index for the evaluation and improvement of root traits contributing to tolerance of crops to soil waterlogging.

Soil flooding is a compound abiotic stress that alters soil properties and limits atmospheric gas diffusion (O
and CO
) to the roots. The involvement of abscisic acid (ABA) in the regulation of soil flooding-specific genetic and metabolic responses has been scarcely studied despite its key importance as regulator in other abiotic stress conditions. To attain this objective, wild type and ABA-deficient tomatoes were subjected to short-term (24 h) soil waterlogging. After this period, gas exchange parameters were reduced in the wild type but not in ABA-deficient plants that always had higher
and
. Transcript and metabolite alterations were more intense in waterlogged tissues, with genotype-specific variations. Waterlogging reduced the ABA levels in the roots while inducing PYR/PYL/RCAR ABA receptors and ABA-dependent transcription factor transcripts, of which induction was less pronounced in the ABA-deficient genotype. Ethylene/O
-dependent genetic responses (ERFVIIs, plant anoxia survival responses, and genes involved in the N-degron pathway) were induced in hypoxic tissues independently of the genotype. Interestingly, genes encoding a nitrate reductase and a phytoglobin involved in NO biosynthesis and scavenging and ERFVII stability were induced in waterlogged tissues, but to a lower extent in ABA-deficient tomato. At the metabolic level, flooding-induced accumulation of Ala was enhanced in ABA-deficient lines following a differential accumulation of Glu and Asp in both hypoxic and aerated tissues, supporting their involvement as sources of oxalacetate to feed the tricarboxylic acid cycle in waterlogged tissues and constituting a potential advantage upon long periods of soil waterlogging. The promoter analysis of upregulated genes indicated that the production of oxalacetate from Asp
Asp oxidase, energy processes such as acetyl-CoA, ATP, and starch biosynthesis, and the lignification process were likely subjected to ABA regulation. Taken together, these data indicate that ABA depletion in waterlogged tissues acts as a positive signal, inducing several specific genetic and metabolic responses to soil flooding.

Evaluating the Impact of Increased Precipitation on UK Grassland Ecosystems and Soil Carbon Sequestration
2025
Climate-driven alterations in precipitation patterns increasingly threaten the sustainability of temperate grasslands, yet the ecological impacts of sustained rainfall increases remain poorly understood. This review addresses the core question: how do prolonged increases in precipitation influence soil carbon sequestration, plant community structure, and ecosystem functioning in UK grasslands? Through a systematic synthesis of recent experimental, observational, and modeling studies, we clarify the mechanisms underlying grassland responses to persistent wetter conditions, define critical ecological thresholds, and identify varied ecosystem sensitivities across different landscapes. Our findings demonstrate that while moderate increases in rainfall can enhance soil carbon storage and plant productivity, excessive and sustained precipitation often leads to soil waterlogging, shifts toward anaerobic microbial processes, reduced biodiversity, and diminished ecosystem resilience. We propose targeted strategies for adaptive management, including improving drainage infrastructure in vulnerable regions, selecting plant species with diverse functional traits to maintain resilience, and establishing robust long-term monitoring programs. This integrative analysis provides essential guidance for land managers and policymakers to sustain grassland ecosystem services under future climate scenarios.
