摘要

农业是一个复杂的系统,在一段时间内,它的多个组成部分之间存在着持续的相互作用。农业实践所涉及的一系列活动为确保人类的粮食安全作出了巨大贡献。随着时间的推移,农业部门面临着多样化的挑战,如快速增长的人口对粮食的高需求、可用资源的稀缺以及气候变化的不利影响。在孟加拉国这样的发展中国家,粮食自给主要是通过集约化农业实现的,这对自然资源、周围环境和整个生态系统都有不利影响。该审查试图发现保护性农业做法对孟加拉国小农的可持续作物生产力和经济盈利能力的潜力。研究表明,保护性农场管理实践是一种具有成本效益的现代化技术,能够通过最低限度地利用农业投入来提高作物生产力和农民收入。尽管保护性农业的概念在世界其他地区得到了广泛的实践,但在过去几年中,孟加拉国的采用速度很慢。该研究的政策含义表明,政府应采取包括公共和私营部门组织在内的协调和联合倡议,将这一概念纳入孟加拉国的主流农业系统。

Conservation Agriculture for Sustainable Crop Productivity and Economic Return for the Smallholders of Bangladesh: A Systematic Review
Agricultural farming is a complicated system that involves continuous interactions among its multiple components over a period of time. The series of activities involved in farming practices have enormous contributions to ensure food security for the humanity. With the passage of time, agriculture sector faces diversified challenges like high food demand of rapidly growing population, scarcity of available resources and adverse effect of climate change. In developing countries like Bangladesh, food sufficiency is mostly achieved through intensive farming which has detrimental effects on natural resources, surrounding environment, and the whole ecosystem. The review attempts to discover the potentials of conservation agriculture practices for sustainable crop productivity and economic profitability of smallholder farmers in Bangladesh. This study revealed that conservation farm management practice is a cost-effective modernized technique that has the ability to accelerate crop productivity and farmers income through minimum utilization of agricultural inputs. Although the concept of conservation agriculture is widely practiced in other parts of the world, Bangladesh is experiencing a slow rate of adoption during the last few years. The policy implication of the study suggests that the government should take coordinated and combined initiatives involving both public and private sector organizations to incorporate this concept into the mainstream agricultural system of Bangladesh.
