Low crop yields due to low rains influenced by change in climate

Farmers rely on consistent rainfall for planning their planting and harvesting schedules. Unpredictable patterns can disrupt these plans, leading to lower yields and potentially failed crops. Extended periods of low rainfall create drought conditions, reducing soil moisture. Insufficient water availability affects germination, stunts crop growth, and decreases overall productivity.

 Heavy rainfall can lead to floods, damaging crops and infrastructure. Floodwaters can erode topsoil, affecting soil fertility, and the standing water can drown plants, causing significant losses.  Excessive moisture provides a breeding ground for various plant diseases, such as fungi and bacteria. Crop diseases can quickly spread in wet conditions, leading to crop failure.

 Heavy rains can wash away the topsoil, which is rich in nutrients. Erosion depletes soil fertility, making it less conducive for crop cultivation and reducing agricultural productivity. Intense rains can lead to flooding and landslides, damaging crucial agricultural infrastructure. Broken roads and disrupted irrigation systems hinder transportation of goods and water supply for crops.  Untimely rains can delay planting and harvesting seasons. Crops planted or harvested late may face unfavourable weather conditions, resulting in reduced yields.  Alternating periods of drought and heavy rainfall create stress on crops. Lack of water during critical growth stages can lead to stunted growth and poor yields.  Altered rainfall patterns may render certain areas less suitable for traditional crops. Farmers may need to adapt by selecting different crops or face challenges in finding suitable lands for cultivation.

 Many small-scale farmers depend on rain-fed agriculture. Insufficient or excessive rains can jeopardize their livelihoods, leading to food insecurity, economic hardships, and potentially forcing migration.

To address these challenges, sustainable water management practices, resilient crop varieties, and improved irrigation systems are crucial. Additionally, farmers and policymakers need to develop strategies for adapting to changing rainfall patterns and mitigating the impact of extreme weather events on food production.
