摘要

现代农业严重依赖土壤。由于侵蚀、土壤养分枯竭和气候变化,土壤的承载能力正在下降。再生农业是一种种植植物和动物的方式,它能丰富和恢复表层土壤,进而改善水循环。尼泊尔还面临着传统农业系统的不良影响。因此,这篇评论文章试图强调一些适合尼泊尔的替代生产系统。研究结果表明,再生农业技术通过最少的耕作、较少的农业投入、较少的劳动力、较少的灌溉消耗来降低生产成本,通过作物残茬、作物轮作、土壤覆盖来保持土壤水分、持水能力和养分价值,减少土壤侵蚀和顶层土壤径流,并通过土壤固碳来提高土壤肥力,减轻气候变化的影响。再生农业的主要制约因素是缺乏适当的信息和技术。对于政策制定者、农民以及食品加工和销售公司来说,再生农业是一种对环境影响较小的替代生产系统。因此,为了促进确定和发展的再生农业实践,在农民的领域进行参与性研究,并在全国的生态领域进行大规模示范。

Regenerative Agriculture and its Prospects in Nepal: A Review
Modern agriculture is heavily dependent on soil. Soil’s carrying capacity is being decreased these days due to erosion, depletion of soil nutrients and climate change. Regenerative agriculture is a way of farming both plants and animals that enriches and restores topsoil, and in turn, improves the water cycle. Nepal is also facing the ill effects of the conventional agriculture system. Therefore, an attempt has been made in this review article to highlight some of the alternative production systems suitable for Nepal. The findings of this review paper were about regenerative agriculture technology reduced the cost of production through minimum tillage, less use of agriculture inputs, less labor, consumption of less irrigation, maintaining soil moisture, water holding capacity and nutrient value through crop residue, crop rotation, soil cover, reduced soil erosion and run off top layer soil and increases the soil fertility through soil carbon sequestration that mitigates the climate change effects. The major constraints of regenerative agriculture are the lack of appropriate information and technologies in hand. For policymakers, farmers and food processing and marketing companies, regenerative agriculture has been an alternative production system with lower impacts on the environment. Therefore, to promote the identified and developed regenerative agricultural practices, participatory research in the farmer’s field with large-scale demonstration across the egro-ecological domains of the country.
