Enhancing agricultural productivity through improved fertilizer accessibility: insights from a contingent valuation study in Eastern Nepal
摘要
The use of chemical fertilizers in paddy farming is necessary to address the issues of food insecurity and low total productivity in agriculture. In regions like Nepal, agricultural productivity often faces constraints due to insufficient access to chemical fertilizers, prompting a critical need for governmental intervention. This study examines the factors affecting farmers’ WTP for chemical fertilizers and identifies the obstacles to timely and adequate chemical fertilizers. This study employs a rigorous contingent valuation method to explore the Willingness to Pay (WTP) among paddy farmers in the Sunsari district of Eastern Nepal for chemical fertilizers. A multistage sampling technique was implemented to select the sample of 407 paddy farming households systematically. A meticulously structured questionnaire was administered, and a Tobit Model was deployed to discern the determinants influencing WTP. Respondents were asked the maximum amount they were willing to pay for chemical fertilizers available in a timely and adequate quantity. The findings expose a significant gap between the actual receipt of chemical fertilizers and farmers' expressed willingness to pay a higher cost for timely and adequate supplies. Astonishingly, despite the willingness of a majority of farmers (81.82%) to pay an additional average price of USD 3.55/ton (ranging from USD 0.86/ton to USD 13.22/ton), only 56.8% receive fertilizers on time, and merely 55.8% obtain an adequate level. Interestingly, the study suggests that the government could potentially increase the fertilizer cost by USD 4.13/ton, constituting a 12% increment over the prevailing market price, thereby addressing the expressed WTP and enhancing agricultural output. These findings present a compelling case for immediate policy interventions aimed at refining fertilizer distribution channels, improving accessibility, fortifying agricultural productivity, subsidy adjustment according to their ability to pay, and bolstering regional food security in Eastern Nepal.
