**Nicosia, Cyprus** – A welcome surge of water into Cyprus’s reservoirs in recent days has offered a temporary reprieve from drought concerns, pushing current storage levels to 19.8 percent of capacity. While this influx marks a significant improvement over preceding drought-stricken periods, experts caution that the island's water security remains a delicate balancing act, contingent on crucial late-season rainfall.
The past four days have witnessed approximately 3.3 million cubic metres (mcm) of water replenishing the island's dams. This has contributed to a total of 36.8 mcm flowing into reservoirs throughout the current hydrological year, which commenced on October 1st. This figure stands in stark contrast to the meagre 18.6 mcm recorded during the corresponding period of the 2023-2024 hydrological year, a season widely acknowledged as being severely affected by drought. The preceding 2022-2023 hydrological year also proved challenging, with only 24.7 mcm of runoff.
Kyriacos Kyrou, a former director at the Water Development Department (WDD), highlighted the positive trajectory, stating, "If rainfall in March is at normal levels, then overall precipitation will be around average this hydrological year." He further elaborated that the island is presently "almost average in terms of precipitation." This optimistic assessment, however, is tempered by the reality that the current storage figure of 19.8 percent is still lower than the 25.8 percent recorded at the same juncture last year.
The hydrological cycle in Cyprus, like in many Mediterranean regions, is heavily influenced by seasonal rainfall patterns. Historically, years with average precipitation typically see actual runoff into dams reaching approximately 80 percent of the average projected flow. Conversely, exceptional rainfall, such as precipitation 15 percent above the norm, can elevate runoff to as much as 130 percent of the average. The inverse is also true; periods of meagre precipitation, often registering between 50 to 60 percent of the average, result in minimal replenishment of water reserves, as evidenced by the recent drought years.
The immediate implication of the recent rainfall is a projected storage level of around 75 mcm if March precipitation adheres to historical averages. This would bring the dams closer to the levels observed last year, a scenario that, while not ideal, would alleviate immediate anxieties surrounding water scarcity. Nevertheless, the underlying vulnerability persists. The island's reliance on rainfall makes it susceptible to fluctuations in weather patterns, and a prolonged dry spell or a disappointing March could quickly erode the gains made in recent days.
The ongoing situation underscores the imperative for sustained water management strategies. While the recent influx offers a welcome respite, the long-term sustainability of Cyprus's water supply remains a pressing concern, necessitating continuous monitoring and proactive measures to ensure resilience against future climatic uncertainties. The coming weeks, particularly the rainfall patterns throughout March, will be critical in determining the island's water security for the remainder of the hydrological year.
