Background: While pesticides are essential for crop protection and food security, they pose serious risks to human health and the environment. Agro-input dealers can play an important role in mitigating pesticide risks, given that they are a major source of pesticides and plant health information for many developing-country farmers. In this article, we assess the willingness of agro-input dealers to offer integrated pest management-based advisory services and promote pesticide risk reduction through a voluntary certification scheme.

Despite the differential effect of climate events on activities along food supply chains and vice versa, most climate change perception studies in agriculture focus on producers, particularly crop farmers.
