Towards sustainable agricultural land use in Nepal: The role of irrigation and fertilizer application

Abstract: <p>Rice, wheat, and maize are the most important staple food crops in Nepal. Due to the complex topography and climate of the country, and a lack of agricultural inputs, the productivity of the crops has remained low over the last decades, with only moderate increases in recent years. National production cannot meet the national demand for the three crops, and food imports are necessary to close the gap. Climate and demographic change will most likely exacerbate the problem. It is therefore an ob… Show more

“…Flooded rice is one of the major biogenic methane sources [93] and methane in the paddy soil is directly released to the atmosphere through rice plants. To meet the food demand, Nepal's agricultural practices has been dependent on the excessive use of fertilizers [97]. However, the use of fertilizers has resulted in the increased emission of nitrous oxide.…”

“…However, this study finds that it is associated with rising GHG emissions in Nepal's emission scenario. So, considering the trade-off condition between climate action and rising emission from Nepal's agricultural sector, this study recommends an adoption of policies that can enhance its agricultural productivity via stimulating green agricultural practices that minimize the use of chemical fertilizers to reduce the possible emissions from this sector [97].…”
