Abstract

Abstract The Canary Islands are a Spanish archipelago, where the greatest water demand comes from agriculture. Being an outermost European region that receives a large number of tourists per year, the need for greater food sovereignty becomes more important. It is vital to undertake studies on the water footprint (WF) of the main crops, in order to identify the irrigation practices of local farmers and establish recommendations for water saving through improvement of these practices. The results of this study show that the average WF for bananas in the Canary Islands is 340.80 m3 t−1 ± 34.07 and for avocadoes is 1741.94 m3 t−1 ± 286.16. The WF models proposed can explain 92 and 86% of the total variance of the WF for banana and avocado crops, respectively. The WF of both crops can be reduced, and this work can be a starting point for improvement. Farmers will face a change in temperature and water availability due to climate change; useful water saving strategies for local farmers can now be made based on estimation of the WF with yield and net needs data.

火山岛上代表性农作物的水足迹:以加那利群岛为例

加那利群岛是西班牙的一个群岛，其最大的用水需求来自农业。作为欧洲最外围的地区，每年接待大量游客，对更大的粮食主权的需求变得更加重要。至关重要的是对主要作物的水足迹进行研究，以便确定当地农民的灌溉做法，并通过改进这些做法提出节水建议。本研究结果表明，加那利群岛香蕉的平均WF为340.80 m3 t−1±34.07，鳄梨的平均WF为1741.94 m3 t−1±286.16。所提出的WF模型可以分别解释香蕉和鳄梨作物WF总方差的92%和86%。这两种作物的WF都可以降低，这项工作可以作为改进的起点。由于气候变化，农民将面临温度和水资源供应的变化;现在可以根据产量和净需求数据估计世界水流量，为当地农民制定有用的节水策略。

期刊介绍： Renewable Agriculture and Food Systems (formerly American Journal of Alternative Agriculture) is a multi-disciplinary journal which focuses on the science that underpins economically, environmentally, and socially sustainable approaches to agriculture and food production. The journal publishes original research and review articles on the economic, ecological, and environmental impacts of agriculture; the effective use of renewable resources and biodiversity in agro-ecosystems; and the technological and sociological implications of sustainable food systems. It also contains a discussion forum, which presents lively discussions on new and provocative topics.
