Pests are a significant cause of crop losses globally. According to the FAO, pests are estimated to destroy around 20-40% of global crop production annually. These losses not only affect food availability but also result in financial hardship for farmers. Crop losses can vary depending on the type of pest, crop, and region, but the overall impact is substantial.

4.2 Cost of Pest Management

Managing pests in agriculture involves implementing various strategies, including pest surveys, monitoring, prevention, and control measures. The cost of pest management can be significant, as it encompasses expenses related to labor, materials, equipment, and pest control products. Additionally, farmers may need to invest in training and education to stay updated on the latest pest control techniques and regulations.

4.3 Price Increase

The economic impact of pests extends beyond the agricultural sector. When crop losses occur due to pest damage, the reduced supply of certain crops can lead to a price increase in the market. This price increase affects consumers, especially those in low-income communities who may already struggle to afford nutritious food. Additionally, rising food prices can have detrimental effects on national economies and contribute to inflation.

4.4 Reduced Agricultural Productivity

Pest infestations and crop losses ultimately result in reduced agricultural productivity. When farmers are unable to produce crops to their full potential, their incomes decline, and overall agricultural output decreases. Diminished agricultural productivity can have a cascading effect on employment, rural development, and food security. Consequently, addressing the economic impact of pests becomes crucial for sustainable agricultural practices and national economies.

5. Global Scenario

5.1 Developing Countries

Pests have a disproportionate impact on agriculture in developing countries.
