确保国家粮食系统有能力承受波动和冲击是一个日益令人关切的问题。考虑到涉及的复杂过程，需要对关键食品系统进行多标量、多应激源分析。本文对墨西哥玉米系统进行了多标度分析，以洞察该部门的演变。文献表明，在过去30年里，气候趋势、国内和国际市场动态以及国内政策变化影响了墨西哥的玉米部门。相比之下，这项研究没有发现玉米被广泛抛弃的确凿证据。此外，虽然经济全球化和气候变化往往被认为是墨西哥玉米部门变化的主要驱动力，但这项研究的结果表明，国内政策对该部门的发展具有同等或更大的影响。与国际市场一体化相比，相对较近的商业供应在墨西哥境内的地理集中度增加了国家对影响主要供应区域的特殊冲击的敏感性。从这个角度来看，墨西哥各地小农的坚持可能是加强国内粮食安全和国家一级复原力的政策努力中一项未得到充分利用的战略资产。墨西哥的情况说明了积极的国内政策在塑造国家粮食系统对内部和外部冲击的敏感性方面的潜在作用。(C)2018爱思唯尔有限公司。保留所有权利。
Ensuring that national food systems have capacity to withstand volatility and shocks is a growing concern. Given the complex processes involved, multi-scalar, multi-stressor analyses of critical food systems are needed. This paper presents a multi-scalar analysis of the Mexican maize system to provide insight into the sector's evolution. The literature suggests that, over the last 30 years, climate trends, domestic and international market dynamics, and domestic policy changes have affected Mexico's maize sector. In contrast, this study finds no conclusive evidence of wide-spread abandonment of maize. In addition, while economic globalization and climatic changes are often presented as the primary drivers of change in Mexico's maize sector, results of this study show that domestic policy has been equally, if not more, influential in the sector's evolution. More than international market integration, the relatively recent geographic concentration of commercial supplies within Mexico has increased national sensitivity to idiosyncratic shocks affecting the dominant supply region. In this light, smallholder persistence across Mexico may represent an underutilized strategic asset in policy efforts to enhance both domestic food security and national-level resilience. The Mexican case illustrates the potential role for proactive domestic policy in shaping sensitivities in the national food system to both internal and exogenous shocks. (c) 2018 Elsevier Ltd.
