In a groundbreaking study published in ‘Environmental Research Communications’, Charles Cachipuendo from the Environmental Science Research Group at Universidad Politécnica Salesiana in Quito, Ecuador, has unveiled an innovative approach to enhancing rose cultivation while addressing pressing water scarcity issues. This research, conducted in the Pisque River basin over a span of seven years, highlights the significant potential of rainwater harvesting in agricultural practices, particularly within the context of greenhouse floriculture.
The study reveals that the area dedicated to rose production has surged by an astonishing 70% since 2016, a trend that accelerated notably after the COVID-19 pandemic. This increase is not merely a statistic; it represents a shift in agricultural practices that could have far-reaching implications for the water, sanitation, and drainage sectors. “By capturing and utilizing rainwater, we can significantly reduce the reliance on conventional water sources, which are becoming increasingly scarce,” Cachipuendo noted.
Through advanced remote sensing techniques, the research quantified the expansion of greenhouse areas and evaluated the efficiency of rainwater capture systems. The findings are striking: a total of 5,473.54 hectares of greenhouses have been identified, capable of capturing rainwater with an impressive efficiency of 93%. This capability allows for rainwater to meet 35% of the annual water needs for crop irrigation, presenting a viable solution to the challenges posed by traditional linear agricultural practices that often exacerbate water scarcity and pollution.
The implications of this research extend beyond the immediate benefits to rose production. It suggests a transformative shift from a linear economy, which prioritizes maximum crop yield and resource consumption, to a circular economy that emphasizes sustainability and resource efficiency. As Cachipuendo explained, “This approach not only conserves water but also promotes a more sustainable agricultural model that can be replicated in other regions facing similar challenges.”
As the global agricultural sector grapples with the dual pressures of increasing demand and diminishing water resources, Cachipuendo’s findings could serve as a blueprint for future developments. The integration of rainwater harvesting systems into greenhouse operations could lead to enhanced water management practices, ultimately fostering resilience against climate variability and ensuring food security.
This research underscores the critical intersection of agriculture and water management, highlighting how innovative practices can contribute to sustainable development. As the world moves towards more sustainable agricultural practices, the insights gained from this study could inspire similar initiatives globally, reshaping how we think about water use in agriculture.
