ELRHA – (Enhancing Learning and Research for Humanitarian Assistance) is launching a series of challenges where they are looking for specific products/processes that address particular water, sanitation and hygiene problems. For instance, the first challenge is to find a solution for latrine lighting in camp settings. If you think you may have a solution for this please read the challenge scope and apply online at www.innocentive.com/hif. In the coming weeks a second challenge in solid waste management will be released – you can check for updates on www.humanitarianinnovation.org
