Assessing the economic and nutritional value of pollination services in Nepal

Abstract

Abstract Pollination is a key agroecosystem service crucial for agriculture production and integrates economic growth, social inclusion, and environmental protection. Understanding the economic value of pollination and its impact on human health and nutrition is essential for effective pollinator conservation and management. This study evaluates the economic and nutritional value of pollination and assesses changes in reliance on pollination over the decades in Nepal. We estimate the economic value of pollination services in Nepal at US $477 million, representing 9% of total agricultural revenue. Pollinator-dependent crops, particularly fruits and vegetables are the source of essential nutrients; 40% of plant-based vitamin A and 14% of vitamin C are directly attributable to insect pollination. The cultivated area of these pollinator-dependent crops has increased by 91% in Nepal during the two decades – 3.7 times faster than equivalent increases in non-pollinator-dependent crops. However, the decline in wild pollinators poses a threat, leading to potential pollination deficits and crop losses. Therefore, our study underscores the importance of conserving and managing pollinators to ensure sustainable agriculture, food security, and nutrition. Targeted efforts, including policy interventions and conservation strategies, are needed to safeguard pollinator populations and enhance pollination services.
