<p>Professor <strong>Sera Young</strong> explains that water security depends on <strong>availability, accessibility, quality, and reliability</strong>. A household may have water, but if access is restricted, unsafe, or unreliable, they still face <strong>water insecurity</strong>. To measure this, she developed the <strong>Household Water Insecurity Experiences (HWISE) and Individual Water Insecurity Experiences (IWISE) scales</strong>, now used in over 50 countries. Her research highlights why <strong>measuring water insecurity is key to solving it</strong>.</p>
