摘要

粮食安全是国家安全话语中不可或缺的一部分,与土地、水、种子和肥料等农业投入直接相关。任何国家的粮食生产能力主要取决于投入是否充足。由于孟加拉国三分之一的人口仍处于粮食不安全状态,本研究考察了投入短缺对该国粮食安全的性质和影响。通过专题内容分析、时间序列数据和关键的解释方法,研究结果表明,尽管孟加拉国实现了粮食自给自足,但由于耕地减少、水资源短缺、肥料和种子市场治理不善以及银行贷款支持不足,该国面临着粮食生产大幅减少的威胁。该研究表明,由于化肥的过度和不平衡使用,孟加拉国的土壤肥力下降,由于种子市场的结构性弱点,三分之二的农民不能按时以公平的价格获得改良种子。这个南亚国家在灌溉方面也面临着严重的威胁,因为该国正在日益失去地表水和地下水。此外,每年有1%的农业用地因土地转用而遭到破坏。在此背景下,本文探讨了减少投入部门关键限制的一些政策选择,可以与现有的粮食和农业政策进行对话。

Bangladesh's food security under input problems: An analysis of constrains and policy response
Abstract Food security is integral to national security discourse directly related to agricultural inputs such as land, water, seeds, and fertilizers. The food production capacity of any country depends mainly on the adequacy of inputs. This study examines the nature and implications of input scarcity in Bangladesh's food security because the state's one‐third of people remain food insecure. With thematic content analysis, time series data, and a critical interpretive approach, the findings show that though Bangladesh achieved self‐sufficiency in food grains, the country faces a substantial reduction threat to food production due to declining cultivated land, water scarcity, poor fertilizer and seed market governance, and inadequate support of bank loans. The study reveals that Bangladesh's soil fertility decreases due to the excessive and imbalanced use of chemical fertilizers, and two‐thirds of farmers do not get improved seeds at fair prices on time because of structural weaknesses in seed markets. The South Asian country also faces a severe threat on the irrigation front as the country is losing surface and groundwater increasingly. Moreover, 1% of agricultural land is ruined yearly due to land conversion to other sectors. Against these backdrops, this article has explored some policy options for reducing the critical constraints in the input sector, which can create a dialogue with existing food and agriculture policies.
