Environmental activists in Karnataka have issued a stark warning about the escalating impact of deforestation on the state’s climate, directly linking the loss of tree cover to increasingly severe heat waves and climate-induced disasters during the monsoon season. The call for urgent, large-scale afforestation efforts comes amidst growing concerns over the region’s ecological health and its implications for biodiversity and water security.
Deforestation’s Grip on Karnataka’s Climate
Environmentalists argue that the reduction in forest cover is a primary driver behind the altered weather patterns observed across Karnataka. They point to recurring heatwaves and other extreme weather events as direct consequences of this ecological degradation. Shailendra Kavadi, president of Bidar Parisara Vani, emphasized the need for extensive tree plantation drives, particularly in districts like Kalaburagi, to combat rising temperatures and protect the region’s biodiversity. Kavadi highlighted that the current climate-induced events underscore the critical need for ecological conservation.
Studies have indicated that rainfall patterns in parts of Karnataka have been significantly altered over the decades, with North Interior Karnataka and the state’s coastal regions witnessing a reduction in annual rainfall since 1960. Experts attribute these changes to the loss of forest cover, which affects heat and weather processes. The Western Ghats, a region known for its rich biodiversity and crucial role in regulating climate, has experienced a significant decline in evergreen forest cover due to human pressures and unplanned developmental activities. This loss of forest cover is believed to have modified local rainfall regimes, leading to more extreme weather conditions such as droughts and floods.
Monsoon Disruptions and Water Scarcity
The monsoon season in Karnataka, vital for agriculture and water supply, is also showing signs of instability. El Niño events have been identified as a contributing factor to deficient rainfall in many parts of the state, leading to drought-like conditions and impacting reservoir levels. Deputy Chief Minister G. Parameshwara has stated that available water must be reserved strictly for drinking purposes, and the state is preparing to seek assistance from the Centre to address the worsening drought situation. The Malnad region, in particular, has recorded one of its weakest monsoons in recent years. This erratic rainfall pattern not only affects crop cycles but also poses risks to drinking water availability and groundwater recharge, potentially impacting the next summer’s water supply.
The timing of rainfall is increasingly becoming as critical as the quantity. Delayed onset of the southwest monsoon, coupled with uneven distribution and prolonged dry spells, can compress crop cycles, disrupt agricultural practices, and increase reliance on groundwater. This disruption in the monsoon’s rhythm is becoming a defining climate risk for the country, impacting food security and the livelihoods of millions.
Afforestation Efforts and Policy Neglect
In response to these challenges, the Karnataka government and various organizations have initiated tree plantation drives. The state has an ambitious target of planting 100 crore trees by 2030. Programs like Krishi Aranya Protsaha Yojane aim to incentivize farmers to participate in afforestation, while urban forest schemes focus on increasing green cover in cities like Bengaluru. However, despite these efforts, issues such as the felling of thousands of trees for infrastructure projects in cities like Bengaluru continue to exacerbate the problem. Experts warn that the unchecked urbanisation and concretisation are pushing trees to the brink, leading to increased incidents of tree falls during monsoon storms, sometimes with tragic consequences.
Research in the Western Ghats has also revealed that the leaves of many tropical forest and agroforestry species are reaching temperatures that could cause irreversible heat damage. This indicates that these plants may already be living close to their thermal tolerance limits, raising concerns about their ability to adapt to future climate scenarios with increased extreme temperatures. The scientific community stresses the vulnerability of tropical species to rising global temperatures and the urgent need for sustainable land-use practices, afforestation, and strengthened environmental policies to mitigate the climatic consequences of deforestation.
The continuous loss of green cover, coupled with inadequate maintenance and policy neglect, has created a precarious environmental situation. Experts emphasize that protecting the city’s green canopy and ensuring ecological balance requires a collective effort towards sustainable urban planning and robust environmental conservation measures.
