Causes and Triggers of Landslides in Wayanad
Wayanad, a picturesque district in northern Kerala, has faced recurrent landslides, primarily due to a combination of natural and anthropogenic factors. A primary natural catalyst is the area’s heavy monsoon rains. These torrential downpours, typical of the region, significantly increase soil moisture levels, reducing soil cohesion and stability. When soil saturates to its limit, the resulting fluid pressure can cause slopes to fail, culminating in landslides.
Additionally, deforestation stands out as a critical anthropogenic trigger. The large-scale removal of trees destabilizes the soil, as tree roots play an instrumental role in binding and reinforcing the ground. The absence of this natural reinforcement exacerbates soil erosion and increases the susceptibility of slopes to collapse during heavy rainfall.
Agricultural practices further compound the issue. Traditional methods such as terracing and shifting cultivation disturb the natural slope equilibrium. Over-cultivation, especially on steep terrains, removes the protective vegetative cover, rendering the soil loose and prone to slippage. Moreover, unplanned and excessive use of chemical fertilizers can alter soil structure, further diminishing its stability.
Construction activities, spurred by rapid urbanization, also form a significant part of the problem. Infrastructure developments, including road building and housing, often occur without adequate geotechnical assessments. Such constructions increase pressure on weak slopes, disrupting the natural drainage patterns and making soil and rock masses more vulnerable to movement.
Ultimately, the interplay of these natural and human-induced factors precipitates the frequent landslide events in Wayanad. Heavy monsoon rains, deforestation, agricultural practices, and construction activities each contribute uniquely, yet their combined effect significantly destabilizes the region’s steep slopes. Understanding these causes and triggers is crucial for devising effective mitigation and adaptation strategies to protect this vulnerable landscape from recurrent landslides.
