The Association of Planters of Kerala (APK) has raised concern over intensifying heat wave conditions, warning that prolonged high temperatures and weak pre-monsoon rainfall could severely impact major plantation crops across the State.

APK Chairman T. R. Radhakrishnan said that the current climate stress—marked by abnormally high temperatures and moisture deficit—is already affecting plantation regions and may lead to substantial crop losses if it persists.

Based on field-level assessments, APK estimates that crop losses could range between 15 to 25 per cent in tea, 20 to 35 per cent in natural rubber, 20 to 40 per cent in coffee, and as high as 30 to 50 per cent in cardamom. Such losses will have far-reaching implications for the plantation economy, affecting farmer incomes, employment, and export earnings, he said.

No. of wet days low

He said that the State is experiencing a sharp decline in pre-monsoon rainfall, with only isolated and insufficient showers recorded so far. The number of wet days has been considerably lower than seasonal averages, resulting in extended dry spells and rapid depletion of soil moisture.

The impact of these conditions is now being felt across plantation crops. Tea estates are reporting reduced leaf flush, increased incidence of banjhi shoots, and deterioration in quality. Natural rubber plantations are witnessing a decline in latex flow and disruptions in tapping cycles due to moisture stress. Coffee plantations are facing failure of blossom and backing showers, leading to poor fruit set and increased berry drop. Cardamom plantations are among the worst affected, with widespread wilting, reduced capsule formation, and heightened vulnerability due to changes in microclimatic conditions.

The situation is further aggravated by increasing water stress. Most plantations in Kerala are rain-fed, and the absence of adequate rainfall has severely constrained irrigation. Reports of declining water availability and emerging drinking water scarcity in plantation areas are a cause for concern. In addition, restrictions on outdoor work during peak heat hours are affecting labour productivity and routine operations in estates.

Plea to government

The Association has urged the Government to take immediate and coordinated action by making provision for emergency irrigation support, augmentation of drinking water supply in affected areas, and ensuring uninterrupted power supply for irrigation purposes.

It also called for a scientific assessment of crop losses through commodity boards and research institutions, and the formulation of appropriate relief measures, including compensation mechanisms, if the situation persists.

APK emphasised that the current conditions underline the growing vulnerability of Kerala’s plantation sector to climate variability, and stressed the need for both immediate relief measures and long-term adaptation strategies to safeguard the sustainability of the sector.
