The Philippines usually incurs severe crop losses caused by drought and typhoon-induced flooding. Much of these losses could have been avoided through effective water management and social mobilization for efficient irrigation systems operation and maintenance (O&M). Building the capacity of irrigators’ associations, which are tasked to manage irrigation systems, is therefore crucial. Within the context of managing irrigation systems under normal as well as adverse conditions, this project aimed to improve farmers’ awareness and skills in irrigation water management and application of climate forecast in their decision making. It engaged water management specialists and agronomists to bridge the gap between science-based and more efficient water management techniques and farmers’ traditional practices.
