Empowering the Rainwater Harvesting Movement
The International Rainwater Harvesting Alliance (IRHA) was created in Geneva in November 2002 following recomendations formulated during the World Summit for Sustainable Development in Johannesburg two months earlier. The mandate called for federation and unification of the disparate rainwater harvesting (RWH) movement around the world, to promote rainwater as a valuable water resource and to build on achievements in this field for the fulfilment of the Millennium Development Goals.
In partnership with the most eminent organisations and individuals in the field, the IRHA provides a lobbying and advocacy platform for RWH. It supports the growth of RWH solutions to water supply problems. It also provides a forum for its members to work together or share experiences, and thus for the benefit of people living with water scarcity.
The IRHA Vision and Mission
The IRHA vision is a large use of rainwater in every field of life.
The IRHA promotes the use and management of rainwater as part of:
• Soil and water conservation for food security
|
These strategies the IRHA Secretariat implements through four activities:
• Project implementation
The IRHA Objectives
• To promote Rainwater Harvesting and management as a strategic and sustainable way of achieving the Millennium Development Goal for freshwater. |
