Determining the value of water for rice production in Nam Dinh province under climate change conditions

Abstract

   In the field of providing irrigation services for rice production, irrigation water is still considered a public utility product and service with the support of the State's expenses to ensure food security, water security, and development of local socio-economic. However, the current price of irrigation water does
not fully reflect the value of irrigation water, which leads to the inefficient and economical use of water. The paper will present a cost-based approach to production and supplement the market price slippage of input materials in the management and operation of irrigation systems to determine the real value of
water for wet-rice production before and after considering the climate change scenario. The results of this paper will develop a method and process to determine the value of irrigation water as a basis for building a more reasonable irrigation price calculation mechanism to help the operating units calculate
the correct and sufficient costs manage and repair works and help people use water economically and efficiently. A case study in Nam Dinh province, which is the key agricultural production province of the Red River Delta
