Insights and Implications—High annual rainfall, with its variability and potential for extremes, underscores the need for water management, erosion control, and effective drainage systems in farming practices.
The high annual rainfall provides ample water, beneficial for irrigation, water catchment systems, and supporting robust plant growth. However, the occurrence of both heavy rainfall and significant dry spells necessitates effective water capture and storage systems to manage these extremes.
Planning for heavy rainfall events is crucial to prevent soil erosion and manage runoff effectively, ensuring that water benefits the farm without damaging the infrastructure or landscape.
Design and maintain drainage systems that can effectively manage runoff during heavy rainfall events. This could include the use of permeable surfaces, the construction of swales or French drains, and the use of detention basins to slow down and control the flow of runoff, preventing damage to the farm's infrastructure or landscape.
Actions: Implementing rainwater harvesting, preventing soil erosion, and managing runoff effectively to optimise water use and enhance land resilience
Construct rainwater harvesting systems, such as ponds or swales, to capture and store water during periods of high rainfall. This can provide a water source for irrigation during drier periods, ensuring consistent plant growth and soil moisture levels.
