摘要

背景气候变化日益要求采用气候适应性强的替代作物和可持续管理方法。为解决这些问题,越来越多的人建议用黍和高粱替代玉米,但目前还没有研究比较地中海地区可持续管理下的粮食作物黍和高粱与玉米对环境的影响。本研究首次考察了在意大利艾米利亚-罗马涅大区具有挑战性的气候条件下,雨水灌溉种植的糙米、高粱和玉米在三年期间对环境和经济的影响以及农艺表现。第一项试验旨在比较糙米、高粱和玉米在低投入系统中的农艺表现和水分利用效率。第二个试验旨在比较两种不同的农艺管理系统(低投入和高投入)对土壤肥力和生物多样性的影响。对土壤基本肥力参数进行了监测,并使用坑式陷阱收集和分析了地栖节肢动物。这项研究的最后一项试验旨在运用生命周期评估(LCA)和生命周期成本计算(LCC)方法,评估以往在低投入和高投入系统中种植的谷类作物在环境和经济方面的表现。结果表明,有机高粱和小米作为可行的夏收作物替代品,不仅在产量、用水效率、抗病性和杂草竞争方面具有替代有机玉米的巨大潜力,而且在减少环境和经济影响方面也具有替代传统玉米的巨大潜力。有机管理对土地的积极影响显而易见,包括提高了有益节肢动物的数量和保持了土壤肥力。事实上,利用意大利中北部地区传统种植的玉米和高粱以及所调查的有机实验田的原始数据进行的生命周期评估和生命周期成本比较显示,有机种植作物的全球变暖潜势和富营养化潜势相当,明显低于传统玉米和高粱。在本研究的可持续实践中,高粱和小米在产量和WUE稳定性方面优于玉米,在单位面积产量和潜在收入方面也比玉米节省了成本。

Millets and sorghum as promising alternatives to maize for enhancing climate change adaptation strategies in the Mediterranean Basin

Context

Climate change is increasingly requiring the adoption of both climate-resilient alternative crops and sustainable management practices. Millets and sorghum are increasingly recommended as alternatives to maize in addressing these issues, yet there are no studies comparing the environmental impacts of food-crop millets and sorghum with maize, under sustainable management in Mediterranean area.

Objective

The present study examined for the first time the environmental and economic impacts, as well as agronomic performances, of rainfed cultivated proso millet, sorghum and maize over a three-year period under challenging climatic conditions in Emilia-Romagna region, Italy.

Methods

Different kinds of trials were realized during three years of experimentation in one location in Ravenna province. The first trial aimed to compare proso millet, sorghum and maize agronomical performances and water use efficiency in a low-input system. The second trial aimed to compare soil fertility and biodiversity impacts of two different agronomical management systems (low-input and high input) for the summer crops previously described. Soil basic fertility parameters were monitored and ground dwelling arthropods were collected and analyzed using pitfall traps. The last trial of this study intended to evaluate the environmental and economic performances of the previous cereal crops cultivated in the low-input and high-input systems, applying the Life Cycle Assessment (LCA) and the Life Cycle Costing (LCC) methodologies.

Results

Both organic sorghum and millet showed high potential as viable summer-crop alternatives, not only to organic maize, based on yield, water use efficiency, disease tolerance and weed competition, but also to conventional maize, based on reduced environmental and economic impacts. Positive land impacts including improved beneficial arthropod abundances and preserved soil fertility were evident under organic management. In fact, the comparative LCA and LCC, carried out with primary data from conventionally cultivated maize and sorghum within central-north Italy and the organic experimental field under investigation, showed that the Global Warming and Eutrophication Potential, were comparable between the organically cultivated crops and significantly lower than conventional maize and sorghum.

Conclusions

The results highlighted the potential of sorghum and millet cultivation as rainfed summer-crop alternative to maize in climate-change context, especially in low-input agronomical systems. In particular, under rainfed, organic management over three years, proso millet yielded consistently.

Implications

Under the sustainable practices of the present study, proso millet outperformed maize for yield and WUE stability, as well as potential costs saved, related to the production amount per unit area and potential revenue.
