INTRODUCTION

Climate change poses a significant threat to agricultural systems worldwide, with developing countries like India being particularly vulnerable due to their reliance on climate-sensitive crops. Maize (Zea mays) is a crucial staple in the Indian agricultural landscape, contributing to food security and the livelihoods of millions of farmers. As one of the major cereal crops in India, maize production has been influenced by various factors, including climate variability, land use changes, and technological advancements (Kumar & Choudhary, 2020).

Recent studies have indicated that rising temperatures and erratic rainfall patterns are adversely affecting crop yields and production stability (Ghosh & Singh, 2021). In India, maize is cultivated across diverse agro-climatic zones, making it essential to understand how local climate impacts production trends. This study employs Compound Annual Growth Rate (CAGR) analysis to quantify changes in the area, production, and yield of maize in relation to climate change. By identifying trends over recent decades, this research aims to elucidate the relationship between climatic factors and maize production dynamics, thereby providing insights for developing adaptive agricultural strategies.

Understanding the implications of climate change on maize production is critical for formulating effective policies and interventions. As India strives to enhance food security amid a growing population, recognizing the challenges posed by climate change will be vital for sustaining agricultural productivity (Rathore & Bhattacharya, 2019). This study not only aims to fill the existing knowledge gaps but also seeks to inform policymakers and stakeholders about necessary adaptations to mitigate the impacts of climate change on maize production.

LITERATURE REVIEW

Climate change has emerged as a critical factor influencing agricultural productivity globally, with significant implications for food security. In India, maize plays a vital role in the agricultural sector, both as a staple food and a cash crop. Understanding the interaction between climate change and maize production is crucial for developing effective strategies to mitigate adverse impacts and enhance resilience.

Numerous studies have documented the effects of climate change on agriculture, highlighting changes in temperature and precipitation as primary drivers of crop yield variability. According to Lobell et al. (2011), rising temperatures can directly affect crop physiology, leading to decreased yields in heat-sensitive species such as maize. In India, the increasing frequency of extreme weather events such as droughts and floods has exacerbated the vulnerability of agricultural systems (Rathore & Bhattacharya, 2019).

Maize production in India has experienced significant fluctuations over the years, influenced by both climatic and non-climatic factors. Kumar and Choudhary (2020) examined trends in maize production and identified a correlation between changing climatic conditions and production levels. Their research indicates that while some regions have adapted through improved practices and technology, others have faced declining yields due to climate variability.

The use of Compound Annual Growth Rate (CAGR) as a metric for analyzing agricultural trends has gained traction in recent research. CAGR provides a clear picture of growth rates over time, allowing for the evaluation of the impacts of various factors, including climate change. Singh and Singh (2022) utilized CAGR to assess the long-term trends in maize production in India, highlighting significant regional disparities influenced by climatic factors. Their findings suggest that understanding these trends is essential for developing targeted agricultural policies.

The literature emphasizes the importance of adaptation strategies to mitigate the effects of climate change on maize production. Several studies advocate for the adoption of climate-resilient agricultural practices, such as improved irrigation techniques, drought-resistant varieties, and integrated pest management (Sharma et al., 2020). These strategies are essential for enhancing the adaptive capacity of farmers in the face of changing climatic conditions.

The existing literature underscores the critical role of climate change in shaping maize production trends in India. Through CAGR analysis, researchers can gain valuable insights into the relationships between climate variables and agricultural productivity. The findings call for immediate policy interventions and adaptive strategies to safeguard maize production, ensuring food security for the growing population in India.

Assess the Effects of Climate Change

Maize is a crucial crop in India, grown both for human consumption and as fodder. However, changing climate conditions, including shifts in temperature, rainfall patterns, and extreme weather events, have had significant impacts on maize production across different regions in the country.

Temperature Shifts

• Optimal Temperature Range: Maize requires a temperature range of 18°C to 32°C for optimal growth. Any deviations from this range—particularly extreme heat—negatively affect the crop. Higher temperatures, especially during sensitive growth periods like pollination and grain filling, lead to reduced yields due to heat stress.
• Impact of Rising Temperatures: In regions such as northern India (e.g., Punjab, Haryana), increasing temperatures have caused heat stress during the growing season, which shortens the growing period and reduces yields. Particularly in summer and early monsoon planting seasons, maize has become vulnerable to unseasonal heatwaves.
• Regional Variation: While northern states are more affected by heat, southern states like Karnataka and Andhra Pradesh have seen relatively less impact from heat stress, but rising temperatures still threaten productivity.

Rainfall Patterns

• Monsoon Dependency: Maize cultivation in India largely depends on the monsoon season, especially in regions like Maharashtra, Madhya Pradesh, and Uttar Pradesh. Variability in monsoon onset, distribution, and intensity has significantly impacted maize production.
• Delayed or Erratic Rainfall: Changes in monsoon timing have delayed planting in rainfed maize regions, leading to shorter growing seasons and lower yields. For instance, erratic rains in the Deccan Plateau (Andhra Pradesh, Karnataka) have disrupted traditional farming patterns.
• Excess Rainfall and Flooding: Excessive rainfall during critical growth stages can damage crops, as seen in eastern India (e.g., Bihar, Odisha), where monsoon floods frequently destroy maize fields. Waterlogging and soil erosion also contribute to reduced productivity.

Droughts

• Water Scarcity: Droughts are particularly detrimental to maize because the crop requires sufficient water during key stages like germination and tasseling. In drought-prone regions like Rajasthan and parts of Maharashtra, reduced water availability has significantly lowered maize yields.
• Rainfed Agriculture: Since maize is predominantly grown under rainfed conditions, droughts lead to a major decline in production. Farmers in regions with inadequate irrigation infrastructure, such as Central India, face acute crop losses during drought years.

Extreme Weather Events

• Cyclones and Storms: In coastal states like Odisha and Andhra Pradesh, cyclones and heavy storms during the monsoon season frequently damage standing maize crops, reducing yields and causing post-harvest losses.
• Hailstorms: Hailstorms are an intermittent yet destructive phenomenon in northern states like Punjab and Himachal Pradesh. These storms, often occurring during the pre-monsoon season, can destroy entire fields within hours.

Pests and Diseases

• Pest Proliferation: Warmer temperatures and increased humidity create favourable conditions for pest infestations, such as the spread of the fall armyworm (Spodoptera frugiperda), a pest that has devastated maize crops across many states since it was first detected in India in 2018. The pest thrives in warmer, wetter climates, which have become more prevalent due to changing climate patterns.
• Disease Prevalence: Similarly, diseases like maize rust and leaf blight have increased due to the changing climate, further reducing yields in susceptible areas.

Regional Overview

• Northern India (Punjab, Haryana): Rising temperatures, erratic rainfall, and increased risk of hailstorms have caused significant fluctuations in maize productivity.
• Eastern India (Bihar, West Bengal, Odisha): Flooding, delayed monsoons, and cyclonic activity are the primary threats to maize production.
• Central India (Madhya Pradesh, Maharashtra): Droughts and erratic rainfall patterns have significantly reduced rainfed maize yields.
• Southern India (Andhra Pradesh, Karnataka): Cyclones and uneven rainfall distribution affect coastal regions, while interior regions suffer from drought and high temperatures.

Adaptation Strategies

• Drought-Resistant Varieties: Development of drought-tolerant maize hybrids, particularly in dry regions like Rajasthan and Maharashtra, helps to mitigate the impact of water scarcity.
• Irrigation Expansion: Expanding irrigation systems in rainfed maize regions such as Madhya Pradesh and Karnataka can help stabilize production during erratic monsoon periods.
• Climate-Resilient Cropping: Farmers in cyclone-prone coastal areas are beginning to adopt shorter-duration maize varieties and alter planting schedules to avoid the peak storm seasons.
• Integrated Pest Management: Addressing pest problems through integrated pest management (IPM) strategies, including biocontrol and monitoring, is crucial to protect crops from climate-driven pest outbreaks.

Climate change poses a complex challenge to maize production in India, with regional variations in the intensity and type of impacts. Temperature extremes, erratic rainfall, and extreme weather events have directly affected yields, with droughts and heat stress posing significant threats in rainfed regions. Adaptation efforts, such as the adoption of drought-tolerant varieties, improved irrigation, and pest management, are key to ensuring the resilience of maize production in the face of these changing climate patterns.
