Climate Change and Global Agriculture: Addressing Challenges and Adaptation Strategies

Climate change poses significant challenges to global agriculture, affecting crop production, food security, and the livelihoods of millions worldwide. This paper reviews the current understanding of the impact of climate change on agriculture and explores adaptation strategies to mitigate its adverse effects. Climate change-induced phenomena such as rising temperatures, altered precipitation patterns, increased frequency of extreme weather events, and shifts in pest and disease dynamics threaten crop yields and agricultural productivity. To address these challenges, various adaptation measures are being implemented, including the development and adoption of climate-resilient crop varieties, improved water management techniques, agroforestry practices, and enhanced early warning systems. Furthermore, policy interventions and international collaborations are crucial for building resilience and promoting sustainable agricultural practices in the face of climate change. This review highlights the urgent need for concerted efforts at local, national, and global levels to safeguard agricultural systems and ensure food security in a changing climate.

Which contributes more in predictor of desert shrubs traits: Intra-annual or inter-annual precipitation change?

Considering the implications of future climatic shifts, mid-latitude desert ecosystems will experience pronounced changes in precipitation dynamics, as evidenced by the elevated inter-annual variability and escalated annual incidence of extreme rainfall events. Despite considerable research on vegetation response to intricate precipitation patterns at the community level, the physiological adaptations of individual plants within these assemblages are not well defined. This investigation employed simulations of diverse precipitation scenarios, utilising varying precipitation amounts (to simulate inter-annual variability) and intervals (to simulate intra-annual variability). A field-manipulated experiment was conducted to assess the responses of the leaf and stem hydraulic functional traits of Artemisia ordosica under different precipitation regimes. The results demonstrated that 1) the magnitude of inter-annual precipitation, rather than the intra-annual redistribution of precipitation, dominated the variability in the functional traits of A. ordosica, with diminished inter-annual precipitation inducing an array of functional trait alterations (e.g., specific leaf area, stomatal conductance, water use efficiency, and conduit diameter) to enhance water-use safety. Reallocating precipitation to low-frequency but high-intensity events during years with less inter-annual precipitation was more advantageous for the survival of A. ordosica. 2) A reduction in annual precipitation fostered a correlation between stem and leaf functional traits in A. ordosica (e.g., hydraulic conductance with photosynthetic rate, stomatal conductance, conduit diameter with transpiration rate, and water use efficiency), suggesting that under decreased precipitation, A. ordosica strengthens the coupling between hydraulics and photosynthesis to prevent hydraulic failure, demonstrating a safer survival strategy. Overall, the impact of global changes in precipitation patterns on the individual survival of A. ordosica primarily depended on the variation in inter-annual precipitation rather than the within-year redistribution. This study enhanced our understanding of the adaptability of dominant shrub species within desert shrub communities to altered precipitation patterns under climate change.

A Review on the Relationship of Climate Variability and Extremes with Crop Production

Risks are always present in agriculture for a variety of reasons. Climate-related risks are the most significant among them since they can occur unexpectedly and cannot be avoided. The main climatic factors influencing crop productivity are rising temperatures, altered precipitation patterns, and rising atmospheric CO2. The average global temperature is expected to rise by 2oC until 2100, which would result in significant global economic losses. The average global temperature is currently rising steadily. The concentration of CO2, which makes up a large amount of greenhouse gases, is rising alarmingly. Climate change, with rising temperatures and increased greenhouse gas emissions, impacts agriculture significantly, leading to varied crop yields and potentially catastrophic economic consequences. While some regions may experience favorable effects, overall, climate variability poses challenges such as reduced crop productivity, increased pest activity, and elevated food costs, particularly affecting underdeveloped nations. Environmental policies must be adaptable and flexible to mitigate these impacts effectively. Farmers' responses to climate change, influenced by perceptions and data accessibility, drive both mitigation and adaptation efforts. Sustainable agriculture, conservation practices, and technological innovations play key roles in mitigating climate change impacts and enhancing resilience in farming communities, though success depends on multiple factors including local perceptions, technical feasibility, and economic viability. This paper reviews the causes of climate change, the climate variables affecting crop production and the mitigation and adaptation strategies against climate change.

A Spatiotemporal Assessment of the Precipitation Variability and Pattern and an Evaluation of the Predictive Reliability of Global Climate Models over Bihar

Climate change is significantly altering precipitation patterns, leading to spatiotemporal changes throughout the world. In particular, the increased frequency and intensity of extreme weather events, leading to heavy rainfall, floods, and droughts, have been a cause of concern. A comprehensive understanding of these changes in precipitation patterns on a regional scale is essential to enhance resilience against the adverse effects of climate change. The present study, focused on the state of Bihar in India, uses a long-term (1901–2020) gridded precipitation dataset to analyze the effect of climate change. Change point detection tests divide the time series into two epochs: 1901–1960 and 1961–2020, with 1960 as the change point year. Modified Mann–Kendall (MMK) and Sen’s slope estimator tests are used to identify trends in seasonal and annual time scales, while Centroidal Day (CD) analysis is performed to determine changes in temporal patterns of rainfall. The results show significant variability in seasonal rainfall, with the nature of pre-monsoon and post-monsoon observed to have flipped in second epoch. The daily rainfall intensity during the monsoon season has increased considerably, particularly in north Bihar, while the extreme rainfall has increased by 60.6 mm/day in the second epoch. The surface runoff increased by approximately 13.43% from 2001 to 2020. Further, 13 Global Climate Models (GCMs) evaluate future scenarios based on Shared Socioeconomic Pathways (SSP) 370 and SSP585. The suitability analysis of these GCMs, based on probability density function (PDF), monthly mean absolute error (MAE), root mean square error (RMSE) and percentage bias (P-Bias), suggests that EC-Earth3-Veg-LR, MIROC6, and MPI-ESM1-2-LR are the three best GCMs representative of rainfall in Bihar. A Bayesian model-averaged (BMA) multi-model ensemble reflects the variability expected in the future with the least uncertainty. The present study’s findings clarify the current state of variability, patterns and trends in precipitation, while suggesting the most appropriate GCMs for better decision-making and preparedness.

Policy strategies for managing food safety risks associated with climate change and agriculture

Managing food safety risks associated with climate change and agriculture necessitates comprehensive policy strategies to safeguard public health, ensure food security, and sustain agricultural productivity. This review delves into the multifaceted challenges posed by climate change on food safety and explores policy approaches aimed at mitigating these risks. Climate change presents a myriad of challenges to food safety, including altered patterns of precipitation, temperature extremes, and increased occurrences of extreme weather events. These changes impact various stages of the food supply chain, from production to consumption, exacerbating existing food safety risks and introducing new ones. Addressing these challenges requires proactive policy strategies that integrate climate adaptation and food safety management. Policy strategies for managing food safety risks associated with climate change encompass a range of measures aimed at enhancing resilience, promoting sustainable agricultural practices, and strengthening food safety systems. One key approach involves the implementation of climate-smart agriculture (CSA) practices, which aim to improve agricultural productivity while minimizing environmental impacts and enhancing resilience to climate change. CSA practices such as crop diversification, soil conservation, and water management can help mitigate the impacts of climate change on food safety by reducing the risk of contamination and enhancing the quality of agricultural products. Furthermore, policies aimed at promoting sustainable food production systems can contribute to mitigating food safety risks associated with climate change. These policies may include incentives for farmers to adopt sustainable farming practices, support for organic farming, and regulations to reduce the use of chemical inputs in agriculture. By promoting environmentally friendly farming practices, such policies can help minimize the occurrence of foodborne pathogens and chemical contaminants in food products, thereby enhancing food safety. In addition to promoting sustainable agricultural practices, policy strategies for managing food safety risks associated with climate change also focus on strengthening food safety systems and enhancing surveillance and monitoring mechanisms. This includes investing in infrastructure and capacity building to improve food safety testing and inspection capabilities, as well as enhancing early warning systems for foodborne disease outbreaks. By strengthening food safety systems, policymakers can better detect and respond to emerging food safety risks exacerbated by climate change, thereby reducing the likelihood of foodborne illness and protecting public health. Furthermore, international collaboration and knowledge sharing are essential components of effective policy strategies for managing food safety risks associated with climate change. Given the global nature of both climate change and the food supply chain, coordinated action at the international level is crucial for addressing shared challenges and exchanging best practices. International organizations such as the World Health Organization (WHO), the Food and Agriculture Organization (FAO), and the World Organization for Animal Health (OIE) play a critical role in facilitating collaboration and providing technical assistance to countries in developing and implementing effective food safety policies in the context of climate change. Managing food safety risks associated with climate change and agriculture requires a multifaceted approach that integrates climate adaptation, sustainable agriculture, and robust food safety systems. By implementing proactive policy strategies that promote sustainable practices, strengthen food safety systems, and foster international collaboration, policymakers can mitigate the impacts of climate change on food safety and ensure the availability of safe and nutritious food for all.

Spatio-temporal analysis of river flow master recession curve characteristics over Ardabil province rivers

The Master Recession Curve (MRC) is a crucial tool for evaluating, managing, and utilizing rivers, particularly under low-flow conditions. Analyzing changes in the MRC of river flow is useful for water resource planning, surface water utilization, and estimating and allocating environmental flow. This study utilized daily flow data from rivers in Ardabil province, Iran over a 48-year statistical period (1970–2015). The Visual Basic program was utilized to estimate the equations and coefficients of recession curves. The trends of the constant and slope coefficients of the MRC equations were determined using the Mann-Kendall test and linear regression. Higher constant coefficient values were attributed to main rivers with higher discharge (e.g., Borran, Mashiran, and Samian, having 17.98, 13.79, and 5.64 cms, respectively. The slope of the MRC in most of the rivers in the central part of the study area exhibited a decreasing trend (p-value<0.05), which attributed to climate change, alterations in precipitation patterns, reduced rainfall/snowmelt, and water abstraction leading to less water input during non-flood periods. Additionally, most rivers in different climatic regions and areas of the study region exhibited an increasing trend (p-value<0.05) in the MRC constants, indicating reduced groundwater recharge or increased groundwater abstraction, as a common issue in the Ardabil province. Moreover, human water use and reservoir regulation (Yamci, Sabalan, Saghezchi, Givi, and small regulating reservoirs) can influence river flow patterns during non-flood periods. The occurrence of droughts and intensified surface water use by farmers, as well as unauthorized extraction of water from wells, have exacerbated this trend.

Climate change and broiler production.

Climate change has emerged as a significant occurrence that adversely affects broiler production, especially in tropical climates. Broiler chickens, bred for rapid growth and high meat production, rely heavily on optimal environmental conditions to achieve their genetic potential. However, climate change disrupts these conditions and poses numerous challenges for broiler production. One of the primary impacts of climate change on broiler production is the decreased ability of birds to attain their genetic potential for faster growth. Broilers are bred to possess specific genetic traits that enable them to grow rapidly and efficiently convert feed into meat. However, in tropical climates affected by climate change, the consequent rise in daily temperatures, increased humidity and altered precipitation patterns create an unfavourable environment for broilers. These conditions impede their growth and development, preventing them from reaching their maximum genetic influence, which is crucial for achieving desirable production outcomes. Furthermore, climate change exacerbates the existing challenges faced by broiler production systems. Higher feed costs impact the industry's economic viability and limit the availability of quality nutrition for the birds, further hampering their growth potential. In addition to feed scarcity, climate change also predisposes broiler chickens to thermal stress. This review collates existing information on climate change and its impact on broiler production, including nutrition, immune function, health and disease susceptibility. It also summarizes the challenges of broiler production under hot and humid climate conditions with different approaches to ameliorating the effects of harsh climatic conditions in poultry.

The analysis encompasses hydrological responses to climate change, including alterations in precipitation patterns, temperature fluctuations, and changes in water availability. Additionally, the study examines the impact of land use changes on streamflow dynamics. Comparative insights from neighboring countries and river basins further illuminate the broader regional implications of climate change on water resources. According to the previous research reviewed in this paper, climate change, land use change, and increment in extreme events (drought) have affected the stream flow over the last decades. The findings underscore the urgent need for adaptive strategies and sustainable water management practices to mitigate the adverse effects of climate change on streamflow and ensure water security in Ethiopia and beyond.

Context‐dependent impact of changes in precipitation on the stability of grassland biomass

Abstract Community stability plays a crucial role in ensuring the consistent provision of ecosystem services despite environmental changes, including alterations in precipitation patterns. Over the past decades, significant progress has been made in understanding the responses of the stability of grassland plant communities and underlying mechanisms, defined as the ratio of the temporal mean biomass to the standard deviation. However, a crucial knowledge gap remains regarding whether the impacts of precipitation on the stability of grassland biomass are contingent upon specific contextual factors. Here, we examined the stability of above‐ and below‐ground biomass in adjacent grass‐ and shrub‐dominated communities through a 7‐year manipulation experiment involving seven precipitation levels: 20%, 40% and 60% decrease, as well as 20%, 40% and 60% increase in natural rainfall, in addition to ambient precipitation. We found that the stability of community biomass was influenced by three contextual factors including the magnitude and directionality of precipitation, above‐ and below‐ground biomass and the type of vegetation. In particular, higher and more intense precipitation resulted in higher stability of above‐ground biomass in both grass‐ and shrub‐dominated communities. Conversely, higher precipitation intensity led to decreased below‐ground biomass stability in grass‐dominated communities but increased below‐ground biomass stability in shrub‐dominated communities. Species stability and species asynchrony consistently played a positive role in explaining the stability of above‐ground biomass in both grass‐ and shrub‐dominated communities. However, species asynchrony negatively influenced below‐ground biomass stability in grass‐dominated communities without a comparable effect in shrub‐dominated communities. The preeminent contribution to the total community biomass was identified in the stability of below‐ground biomass, evident in both grass‐dominated and shrub‐dominated communities. Synthesis. This study highlights that while the specific effects of changes in precipitation may vary depending on the context, the fundamental processes governing biomass stability are consistent. These findings elucidate the desert steppe ecosystems' adaptive response to precipitation variations and emphasize their pivotal role in maintaining ecosystem functions under climatic perturbations.

Modeling the natural vegetation dynamic under climate change scenarios in coastal protected dryland of southeastern Tunisia

According to the Intergovernmental Panel on Climate Change (IPCC), climate change is mainly manifested by severe droughts and rainfall decrease. These effects are multiple and vary from one region to another around the world including rising temperatures, altered precipitation patterns and degradation of the natural flora. The Zarat region (Gulf of Gabes) is notable for its climate variation, shallow waters, high levels of temperature and salinity. Understanding the vegetation dynamics in this coastal protected region under climate change scenarios is important for projection to the whole ecosystems. The Maxent model is used to predict the potential distribution of plant groups and Soil Adjusted Vegetation Index (SAVI) classes for many future time-periods (2021-2040, 2041-2060, 2061-2080 and 2081-2100) under different climate change scenarios in the Zarat region. Main results indicate that variables related to precipitation and temperature are more significant for predicting plants and SAVI classes distributions. Our findings can provide scientific basis for the dryland sustainable management and for plant community’s behavior under climate change.

Genome-wide analysis of PvMADS in common bean and functional characterization of PvMADS31 in Arabidopsis thaliana as a player in abiotic stress responses.

Changing climatic conditions with rising temperatures and altered precipitation patterns pose significant challenges to agricultural productivity, particularly for common bean crops. Transcription factors (TFs) are crucial regulators that can mitigate the impact of biotic and abiotic stresses on crop production. The MADS-box TFs family has been implicated in various plant physiological processes, including stress-responsive mechanisms. However, their role in common bean and their response to stressful conditions remain poorly understood. Here, we identified 35 MADS-box gene family members in common bean, with conserved MADS-box domains and other functional domains. Gene duplication events were observed, suggesting the significance of duplication in the evolutionary development of gene families. The analysis of promoter regions revealed diverse elements, including stress-responsive elements, indicating their potential involvement in stress responses. Notably, PvMADS31, a member of the PvMADS-box gene family, demonstrated rapid upregulation under various abiotic stress conditions, including NaCl, polyethylene glycol, drought, and abscisic acid (ABA) treatments. Transgenic plants overexpressing PvMADS31 displayed enhanced lateral root development, root elongation, and seed germination under stress conditions. Furthermore, PvMADS31 overexpression in Arabidopsis resulted in improved drought tolerance, likely attributed to the enhanced scavenging of ROS and increased proline accumulation. These findings suggest that PvMADS31 might play a crucial role in modulating seed germination, root development, and stress responses, potentially through its involvement in auxin and ABA signaling pathways. Overall, this study provides valuable insights into the potential roles of PvMADS-box genes in abiotic stress responses in common bean, offering prospects for crop improvement strategies to enhance resilience under changing environmental conditions.

Ultra-fine bubble irrigation promotes coffee (Coffea arabica) seedling growth under repeated drought stresses

ABSTRACT Coffee plants are likely to be highly susceptible to changes in climate, and several statistical studies based on projections of altered precipitation patterns have predicted negative effects on coffee growth including the loss of suitable cultivation areas in most coffee-producing countries. Increased drought occurrences owing to climate change are expected to be a new challenge for stable coffee production, because coffee production relies heavily on stable rainfall conditions. In recent years, ultra-fine bubble (UFB) water has been reported to be effective in alleviating environmental stresses for plant growth, especially drought stress. The objective of the present study was to determine the effect of UFB water irrigation on the growth of coffee seedlings to mitigate the stress of repeated droughts. To simulate an environment with frequent droughts, six pot experiments were conducted over 3 years by applying repeated drought stress to coffee plants in a greenhouse. The results showed that UFB water had a remarkable growth-promoting effect on coffee seedlings under drought conditions. In contrast, no significant effect on coffee growth was observed in the environment with sufficient nutrients, in which additional fertilizer was used. UFB water significantly increases the root length and surface area of coffee plants, which may promote water absorption and prevent leaf senescence (leaf cell collapse) under drought conditions. This leads to coffee plants adapting to drought conditions. Therefore, UFB water irrigation may be an effective measure to promote coffee growth in drought conditions.
