Recent advances in sustainable fruit production under climate change conditions

Introduction

Introduction Climate change is among the most powerful drivers influencing global agriculture in the 21 st century. This rise in atmospheric greenhouse gases has caused global warming, modified precipitation patterns, more intense extreme weather events, and evolving dynamics of pests and diseases (Luedeling et al., 2011; Deori et al., 2024). These are important determinants of yield, fruit quality, phenology and spatial distribution for fruit crops. Fruit crops also play an important role in nutritional security due to provision of vitamins, minerals, antioxidants, dietary fiber and phytochemicals. Hence, sustainable production of fruits is prerequisite for ensuring food security and strengthening the rural economy (Tubiello et al., 2021) [43,15,68] . The findings are consistent with earlier reports that high temperature conditions have resulted in early flowering and fruit maturation, fewer chill hours, more water stress and shifting pest populations in the majority of fruit production regions (Salama et al., 2021; Osorio-Marin et al., 2024) [57,51] . Sustainable fruit production in a climate change era calls for a new breed of integrated solutions that promote high productivity, natural resource conservation, and minimal environmental harm. Recent developments in precision horticulture technology, genomics, artificial intelligence, climate-resilient breeding, and regenerative agriculture provide exciting opportunities for climate adaptation (Jena et al., 2023; Gabay and Flaishman, 2024; Cembrowska-Lech et al., 2023) [30,22,11] . The increasing earth surface temperature: A geophysical threatening parameter that is currently increasing and is related to long-term global warming owing to its relation with a buildup of greenhouse gases in the atmosphere (Forster et al., 2023).  Heatwaves: A heatwave, also spelled heat wave, is a period of prolonged abnormally hot weather characteristic of a particular climate (Mora et al., 2017).  Irregular rainfall: Shifts in timing, intensity, and distribution of precipitation that make water availability unpredictable.  Occurrence of drought: Subnormal rainfall for a prolonged time causing water shortage and moisture stress to crops (Lisonbee et al., 2024).

Climate Change and Fruit Production 2.1 Major Climatic Changes Affecting Fruit Crops

 Flooding and waterlogging: is the over-abundance of water on or in the soil that limit root respiration and induce plant growth injury (Pais et al., 2022).  Elevated atmospheric CO2: An increase in the concentration of carbon dioxide in the atmosphere from human sources such as energy production and land use change.  Salinity intrusion: Penetration and accumulation of salts in agricultural lands or fresh water bodies, which impairs crop production (Schubert and Qadir, 2024).  Severe weather events: Strong climatic events such as tornados, storms, heavy rainfall, hail storms, droughts and heat waves that seriously affect agriculture (Sivakumar, 2020) [19,49,41,52,58,62] .

Decreased carbon fixation:

Unfavorable environmental situations inhibit the process of photosynthetic conversion of atmospheric carbon dioxide into the organic matter.

Diminished carbohydrate accumulation:

The inhibited photosynthetic activity leads to reduced synthesis and accumulation of sugar and carbohydrates, thereby influencing the growth of plant and development of the fruit (Jiang et al., 2025) [70,31] .

Respiration

Respiration rate is dramatically increased under high temperature in fruit crops, resulting in depletion of stored carbohydrates and energy reserves. Consequently, the plant's energy efficiency is reduced, with a greater proportion of assimilates being used for maintenance, rather than growth and fruit production (Medda et al., 2022; Raju et al., 2024). Inversion of sugar and water uptake is one cause for decrease in sugar accumulation, flavor, firmness and general marketability of fruit due to overbreathing. Moreover, high respiration rates speed up physiological, making fruits senescent and causing short shelf life and high postharvest losses (Batool et al., 2025) [47,54,6] .

Water Relations

Climate stress mainly heat and drought has a strong influence on the water relations of fruit crops. Higher temperatures lead to an increase in transpiration and water loss from plant tissues. Plants respond to conserve water, under moisture deficit by closing their stomata, which reduces water loss but also limits carbon dioxide entry needed for photosynthesis (Haghpanah et al., 2024). As a result, the efficiency of water use decreases as the plants are less efficient in transfding the water to biomass and fruit yield, and hence in their growth, productivity and fruit quality (Tonet et al., 2026; Nour et al., 2024) [27,66,50] .

Reproductive Processes

Reproductive processes of the fruit crops are also adversely affected due to climate stress resulting in a great loss in productivity. High temperature, drought and other environmental stresses may induce flower abortion, which causes loss of potential fruits prior to fertilization and it is the major reason for low fruit yield. These factors also affect pollinator foraging and pollen viability, resulting in reduced pollination and fertilization (Bacelar et al., 2024). As a result, the fruit set is poor, and only a small proportion of the flowers turn into fruits. Also, most stress conditions tend to induce higher rates of premature fruit drop, which further diminishes the yield (Jena and Pramanik, 2025). Various fruit crops (Apple, Mango, Citrus, Grape, Banana, Guava etc.) have shown considerable physiological & reproductive anomalies in changing climatic scenario, which leads to reduction in fruit yield and quality (Gelaye and Getahun, 2024; Ameen et al., 2023) [5,29,25,2] . [8,16] . Also, high temperature-tolerant genotypes are screened and used when growing under high temperature stress without serious loss of yield and fruit quality. The development and use of salinity-tolerant rootstocks is another key tactic known to significantly contribute to fruit plant establishment in salt-affected soils, through facilitation of water and nutrient acquisition and mitigation of the adverse effects of salt overload. These breeding processes are of great help in attainable fruit production under changing climate scenario (Afonso et al., 2025) [1] .

Marker-Assisted Selection

The fruit crop breeding has been greatly advanced due to MAS which allows the rapid identification of stress tolerant traits relating to drought, heat, salinity, and resistance to pathogens. Breeders can use molecular markers associated with genes of interest to screen plants at an early stage without having to wait until expression of those traits in field conditions (De Mori and Cipriani, 2023; Kumar et al., 2024). This speeds up the selection process, saving both time and money in breeding programs, and also increasing breeding efficiency. [14,38] .

Genomic-Assisted Breeding

Genomic breeding enables identification genes for drought, heat, salinity and other stress tolerances in fruit crops. Tools like Genome-Wide Association Studies (GWAS) allow for the identification of genetic variations associated with favorable traits and enhance the accuracy of breeding and the speed of generation of climate-resilient fruit cultivars (Li et al., 2024; Tyagi et al., 2024).

Gene Editing (CRISPR-Cas)

Gene editing tools, with CRISPR-Cas systems in the lead, allow targeted modifications for the enhancement of tolerance-related traits and for improving resistance against abiotic stress such as drought, heat, and salinity, which contribute to the formulation of climate-resilient fruit crops (Shelake et al., 2022) [61,53,36,39,69,60] .

Sustainable Orchard Management Practices 5.1 Canopy Management

Good canopy management improves light capture and distribution within the tree resulting in increased photosynthetic efficiency and fruit growth. It also reduces heat stress through canopy temperature control, enhances air flow to reduce disease pressure, and results in a more uniform fruit color, and size, and quality, which brings higher returns and better market potential (Brown, 2022) [9] .

Modern Techniques

Modern concepts of canopy and orchard management are based on the findings from the high-density planting, meadow orchard system, and ultra-high-density training systems, precision pruning, and other techniques. Such practices optimize land, light, water, and nutrient usage, and improve the fruit tree canopy and orchard productivity. They provide a higher light transmission, simplification in management, mechanization and harvesting, and they have a positive effect on fruit yield, quality and orchard sustainability in the face of global climate change.

Mulching

Mulching is a keyhole sustainable orchard management operation that consists of application of Mod. rock or fabric or paper or plastic or biodegradable mulches till the soil surface. It preserves soil moisture by decreasing evaporation, prevents weed proliferation, buffers soil temperature and enhances soil health. Organic mulches also play a role in carbon sequestration and increase soil organic matter, ultimately contributing to enhanced resilience and the sustainability of fruit production systems in a changing climate (Ramadhani et al., 2024) [56] .

Cover Cropping

Cover cropping is the cultivation of certain crops between tree rows, or during non-cropping periods, for the purpose of enhancing soil health and orchard sustainability. It changes soil structure through greater organic matter, facilitates N fixation with leguminous cover crops, enhances biodiversity by sheltering other organisms, and prevents soil loss by "anchoring" the soil against wind and water. These effects are associated with increased soil fertility, conservation of resources, and greater resilience to climate in fruit production systems (Girling et al., 2022) [26] .

Precision Horticulture and Digital Agriculture Components

GPS and GIS

GPS and GIS systems provide spatial orchard mapping through precise location of soil, crop health, and environmental differences within an orchard. Such information enables site-specific management, thus the producers have the possibility to adjust the application of water, fertilizers and other inputs in response to the specific needs of different orchard areas, increasing productivity and resource-use efficiency and sustainability (Dainelli and Saracco, 2023) [13] . [17,21] .

Remote Sensing

Drones

Drones (Unmanned Aerial Vehicles, UAVs) are gaining popularity in fruit production to quickly and accurately evaluate canopy, monitor for pests, and diagnose nutrient deficiencies. With sophisticated imaging sensors, drones generate high resolution information, allowing growers to monitor the health of their orchards, detect problem areas at early stages and apply management practices in a focused manner, resulting in increased productivity, decreased input costs and improved sustainability (Ma, 2024) [45] .

Artificial Intelligence

Artificial Intelligence (AI) is revolutionizing the fruit industry with contribution in the accurate yield prediction, early disease detections, enhanced irrigation scheduling, and precise harvesting forecasting. Through processing a massive amount of data, such as data collected by sensors, drones, weather stations, and field surveys, AI enables growers to make better decisions, increase resource use efficiency, mitigate production risks, and improve productivity under a changing climate ( [40,34,35] .

Internet of Things (IoT)

The Internet of Things (IoT) makes it possible to monitor the orchard conditions in real-time with the help of connected sensor nodes and smart devices. It supports soil moisture and crop water requirement-based irrigation scheduling, and environmental sensors monitor temperature, humidity, soil moisture, light intensity continuously (Ashitha et al., 2026). These functions contribute to the efficiency of resource use, decision-making, productivity, and climate resilience of fruit production systems (Jaiswal et al., 2025) [4,28] .

Deficit Irrigation

Deficit irrigation is an approach of irrigation that contributes to water saving by under-irrigating at certain growth stages, under the full crop water demand, without reduction in crop yield or with minimum yield reduction. This approach promotes the tactical management of water and conservation of limited water resources, and it may positively affect fruit quality through increased sugar, fruit firmness or flavor. Thus, deficit irrigation represents an appropriate climate-smart strategy to achieve sustainable fruit production in dry environment (Calabritto, 2025) [10] .

Sensor-Based Irrigation:

Sensor-based irrigation system allows the soil moisture to be monitored in real time with soil moisture sensors and soil water status can be directly observed which can be used to estimate soil water status, and then the water can be applied only according to soil water needs. This precision management enhanced irrigation efficiency, lowered water losses, maximized crop water use, and contributed to the sustainability of fruit production under such climate scenario (Torres-Quezada et al., 2025) [67] .

Rainwater Harvesting:

Harvesting of rainwater how to collect rainwater on your land is done by storing surplus rainwater using farmyard bunding and with water retention structures like farm ponds, reservoirs and groundwater recharging structures at the field level. These systems contribute to water conservation, better groundwater recharge, offer supplementary irrigation in drought periods, and increase robust fruit production systems in facing climate variation and water shortage (Chachar et al., 2026) [12] . [33,48] .

Practices

Regenerative agriculture in fruit production is based on a range of different practices, such as application of compost, biofertilizers, agroforestry, organic amendments, as well as overall soil health management through integrated nutrient management (INM), to rehabilitate the soil and the system. Compost and organic amendments increase soil aggregation, water retention, and availability of nutrients, biofertilizers enhance beneficial microbial communities and nutrient availability. Agroforestry systems promote biodiversity, provide microclimatic regulation, and sequester carbon. Organic and synthetic nutrient sources are used in tandem in integrated nutrient management (INM) to maximize nutrient-use efficiency and to maintain long-term productivity. These practices collectively enhance orchard resilience, mitigate environmental degradation, and facilitate sustainable fruit production in the face of climate variability (Gaeta et al., 2025) [23] .

Benefits

Transitioning to regenerative agricultural systems results in increased soil organic matter content that generates cobenefits including improved soil fertility, structure, and water retention. These practices also trigger beneficial microbial activity, resulting in enhanced nutrient cycling and overall soil quality. Consequently, systems of fruit production are more resistant to climate stresses, such as drought, heat and unpredictable rainfall, allowing for greater sustainability and long-term production.

Rootstock Innovations for Climate Resilience:

Rootstocks have a vital role in improving climate resilience of fruit crops affecting water and nutrient uptake, growth, productivity and stress tolerance. Climate resilient rootstocks are identified for desirable characters such as drought tolerance, salt tolerance, high temperature tolerance and disease resistance to equip fruit plants to survive under unfavourable environments. Adoption of appropriate rootstock gives better performance of the orchard, preserves fruit yield and quality under the climatic strain and has a great implication to sustainable fruit production systems (Srivastava et al., 2026) [63] . [44] .

Examples

Rain Shelters

Rain shelters adequately protect from the damaging effect of too much rain since fruit crops are not directly exposed to heavy rain. They reduce damage to flowers and fruits, as well as fruit cracking and waterlogging, and also the incidence of fungal and bacterial diseases related to high humidity. Offering a semi-controlled growing environment, rain shelters enhance fruit quality, yield stability, and total orchard productivity under diverse weather conditions (Garcia et al., 2024) [24] .

Polyhouses

Polyhouses climate controlled production broadly control temperature, humidity, light and ventilation among other factors. This system of protected cultivation enables fruit crops to be shielded from harsh weather conditions such as high or low temperature, heavy rain, strong winds and even frost. Consequently, polyhouse provide environment for best plant growth, fruit quality and yield, longer production season and better resource use efficiency, and are thus considered as suitable means for sustainable fruit production in the scenario of climate change (Tiwari et al., 2025) [65] .

Insect-Proof Structures

Insect-proof structures (such as net houses and screen houses) serve as a physical barrier for insect pests, hindering their access to the production field. This has a great impact on pest population and insect-borne diseases, resulting in reduced application of chemical pesticides. Therefore these structures have enabled environmentally sustainable production of orchard fruits with reduced cost of production and improved quality of fruits and safe produce with minimum pesticide residue (Kumar et al., 2025) [37] .

Biological Approaches for Climate Adaptation Plant Growth-Promoting Rhizobacteria (PGPR)

Plant Growth-Promoting Rhizobacteria (PGPR) are soil bacteria found in the root zone that can promote the growth of plants by a number of different mechanisms. They promote the availability of nutrients and their uptake through the roots, such as nitrogen, phosphorus, and potassium and the like. PGPRs-mediated enhancement of drought tolerance in fruit crops through increased root growth, water use efficiency and induced physiological and biochemical mechanisms to mitigate the detrimental effects of water stress in fruits and maintained sustainable fruit production under changing climatic conditions (Lone at al., 2026) [42] .

Mycorrhizal Fungi

The mycorrhizal fungi establish a symbiosis with the roots of plants, extending the root system by means of their own hyphae (instead of root hairs) and increasing the amount of soil exploited for water and nutrients. This symbiosis stimulates water absorption and mineral nutrition, in particular phosphorus and micronutrients. Moreover, mycorrhizal fungi enhance adaptation to environmental stresses, such as drought, salinity and extreme temperatures, and thus fruit crop resistance and yield in climate change scenario (Formenti et al., 2026) [18] .

Biostimulants

Biostimulants are derived from natural sources or living organisms and they promote plant growth, nutrient uptake and stress resistance. Typical biostimulants are seaweed extracts, humic acids, and protein hydrolysates. Plant growth regulators and some bioactive compounds and other beneficial compounds, like growth stimulants and antistress agents, can be found in seaweed extracts, while humic substances increase soil fertility, availability of nutrients, and root growth. Protein hydrolysates contain amino acids and peptides that stimulate physiological activities and mitigate the impact of abiotic stress on plants. Biostimulant application has been proven to boost fruit crop growth, yield, and sustainability even in hostile environments (Franzoni et al., 2022) [20] .

Climate-Smart Pest and Disease Management Emerging Challenges

The dynamics of pest and disease in fruit production systems are also affected by climate change, which tends to support the development of new pest outbreaks and the invasion of new areas by those of invasive species. Climate warming and changes in humidity could lead to an increase in plant diseases, and thus in losses in crop yield. Also warmer winters and longer periods of warmth prolong the survival of pests, and their reproduction, as well as their activity during all the year which can add up to intense pressure on fruit crops, due to higher populations of pests. These recommendations are thus of paramount importance for the future fruit production and the implementation of environment-friendly and climate-smart pest and disease management. [55] .

Sustainable Approaches

AI-Based Disease Detection: AI-based disease detection systems are based on more advanced image processing algorithms to detect disease symptoms on leaves, fruits and other parts of a plant with the high precision. Through images taken with mobile phones, drones or sensors, AI is able to detect diseases early, often before they manifest severe symptoms that can be seen with the naked eye. They also facilitate early warning systems by monitoring crop health on an ongoing basis and alerting farmers to the likely onset of a disease, allowing them to take pre-emptive action to reduce crop losses and enhance orchard productivity (Sharma et al., 2026) [59] .

Predictive Modeling

Predictive modeling employs weather data, crop information, and pest or disease monitoring reports to predict outbreaks and the risk thereto. By evaluating environmental conditions that favor the development of pests/diseases and dissemination of pathogens, these models offer early warnings and help timely management decisions. This allows producers to take preventive actions, to minimize crop loss, pesticide use and to increase the sustainability of fruit production systems in the face of changing climatic conditions (Maddeden, 2025) [46] .

Sustainable Post-Harvest Management Recent Innovations

Current advances in post-harvest handling have made it possible to better store, transport, and maintain the quality of fruits. Smart cold storages are equipped with real-time monitoring and control technologies to ensure best storage conditions; Pacif products control atmosphere (CA) storages for fruit slow down fruit respiration with predefined oxygen, carbon dioxide, and temperature levels and extend the shelf life. Modified atmosphere (MA) packaging changes the gaseous environment surrounding the fruit so as to retard spoilage and maintain fruit quality during storage and shipping. IoT-enabled cold chains, such as fresh produce cold chain, are hopping on this trend to enable remote sensing and real time monitoring of temperature, humidity and product condition across the entire supply chain, quality assurance and post-harvest loss mitigation. The traceability systems based on blockchain also improve transparency and food safety in fruit products production to consumption, through enhancing consumer confidence and the efficiency of supply (Thakur et al., 2025) [64] .

Benefits: High-quality postharvest processing is essential for minimizing postharvest loss and ensuring good quality of fruits and vegetables. These technologies enable a longer shelf life of fresh produce, allowing them to maintain nutritional value, color and quality for a longer time by spurring minimal spoilage, as a result of controlled environmental conditions. As a result, fruit is delivered in better condition to consumers, which enhances marketability, provides greater returns to growers, and improves efficiency and sustainability throughout the fruit supply chain.

Future Perspectives

The fruit production systems of the future are anticipated to take advantage of high technology and be more climate resilient through incorporation of cutting-edge technology and sustainable practices. Artificial intelligence, robotics and automation will improve the decision-making process, labor efficiency and precision management, and climateresilient genomics and CRISPR-based breeding will expedite the creation of stress-tolerant fruit cultivars. Digital orchard platforms and autonomous sensing drones will enable real-time crop characterization and data-driven crop management. Smart irrigation techniques will ensure water efficiency in the wake of water competition, whereas carbon-neutral orchestras and circular bio-based economy strategies would help to improve environmental sustainability by means of carbon emission abatement and agricultural resource recovery. In addition, climate-smart policy regimes will create an enabling environment for the scaling out of these innovations to bring about resilient, productive and sustainable fruit production systems that contributed towards building future climate-ready orchards (Khan, 2025) [32] .

Conclusion

Climate change results in severe strain on both the abiotic and biotic factors in the global fruit production system. Sustainable fruit production is expected to be ensured through integrated climate-smart solutions based on resilient cultivars, precision horticulture, regenerative farming, water management, protected cultivation, digital tools and advanced breeding. The latest advances in genomics, artificial intelligence (AI), Internet of Things (IoT), remote sensing, and climate-resilient orchard management provide tremendous potential to improve productivity and sustainability. It is recommended that future research efforts should be aimed at merging technological developments with ecological concepts to build resilient fruit production systems that can fulfill the needs of global food and nutritional security under a backdrop of changing climatic conditions.
