摘要

人口增长和落后的农业生产方式要求提高粮食生产的效率。城市水培作物是应对这一挑战的潜在解决方案。然而,将饮用水用于城市农业并非当务之急。因此,雨水收集可以减少饮用水在人类消费之外的其他用途上的使用。本研究评估了雨水收集用于安第斯城市水培作物生产的效率。我们开发了一个雨水收集模型,用于分析两种水培生产方案的效率和优化:(1) 家庭生产(30 株)和 (2) 小型商业生产(200 株)。我们发现,方案 1 和方案 2 的效率分别为 99.71% 和 75.79%。75.79% 的效率是由于存在低降水期,而在研究地区,低降水期是零星的。此外,如果屋顶收集面积增加到 40 平方米,方案 2 的效率可达到 100%。安第斯城市全年降水持续不断,雨水收集足以为家庭和小规模商业水培生产供水,只需对家庭进行基本改造即可。我们通过将雨水收集与水耕作物相结合来改善城市粮食和水安全,取得了可喜的成果。

Rainwater harvesting as a sustainable solution for the production of urban hydroponic crops
Population growth and poor agricultural practices demand an improvement in the efficiency of food production. Urban hydroponic crops represent a potential solution to this challenge. However, the use of drinking water for urban agriculture is not a priority. Consequently, rainwater harvesting can reduce the use of drinking water for other purposes than human consumption. This study evaluated the efficiency of rainwater harvesting for the production of hydroponic crops in an Andean city. We developed a rainwater harvesting model to analyze the efficiency and optimization of two hydroponic production scenarios: (1) domestic production (30 plants) and (2) small-scale commercial production (200 plants). We found an efficiency of 99.71 and 75.79%, for scenarios 1 and 2, respectively. The 75.79% efficiency is given by the presence of low precipitation periods, which in the case of the study area are sporadic. Furthermore, scenario 2 could reach efficiencies of 100% if the roof capture area increases up to 40 m2. Rainwater harvesting in Andean cities, with sustained precipitation throughout the year, is enough to supply water for domestic and small-scale commercial hydroponic production with basic household modifications. We show promising results by combining rainwater harvesting and hydroponic crops for improving urban food and water security.
