13. Assessing the current situation and proposing circular economy models in agricultural activities in Trinh Xa commune, Phu Ly city, Ha Nam province

Abstract

By methods of field survey and sociological investigation, the study showed that rice and pig farming households in Trinh Xa commune have been applying production methods related to the circular economy. The models related to the circular economy in Trinh Xa commune for rice farming activities include 2 models: Rice - Fertilizer; Rice - Cattle model and 3 models related to livestock production include the Pig - Fish Pond Model; Pig - Rice Model; Pig - Domestic fuel - Cultivation model. The models have been bringing economic, social and environmental benefits to local people, but the application rate is still very low, accounting for only 13.7 % for rice cultivation and 37.5 % for livestock feed. Through the results of the interview about the need for guidance and training on circular economy models applied in pig farming and rice farming, the study proposed activities that the local government of Trinh Xa commune needs to carry out to gradually build a circular agriculture, including building an incentive mechanism to promote the circular economy model, propagating and training people on steps to implement technical solutions of economic circular models in agriculture. As for the technical solution, in addition to the proposal to replicate the models currently being applied, the study also proposed the models of Straw - Growing straw mushrooms - Fertilizer for rice growing households to maximize the use of generated straw, minimize the environmental pollution impact caused by burning straw after harvest. For livestock production, research and propose the development of a Pig - Breeding model - Domestic fuel - Organic fertilizer in order to thoroughly treat waste generated in the pig industry, protect the environment and reduce cooking costs as well as in buying fertilizers for crops.
