Hållbara Konsumtions- och Produktionsmönster • Varför Jordbruk - Vatten?? • 70% av uttaget av vatten från sjöar/vattendrag/grundvatten för jordbruksbevattning- “Blue Water” Men: • Dubbelt så mycket vatten går åt inom regnbevattnat jordbruk - “Green Water” • Fler floder kommer att vara tomma 2025 om en växande befolkning skall få mat!
Closing the Productivity Gap • In rainfed agriculture and irrigated agriculture. • Will require combination of agronomic, plant breeding, economic, social and institutional measures. • Will involve better land and water management, better irrigation management, establishing water rights and institutional frameworks.
Facilitate the diffusion and use of new technologies • Requires attention to water flow patterns: achieve “real” water savings, reduce unproductive evaporation, eliminate flows that cause salinization and high water tables. • Includes both high-tech and low tech, with social marketing and micro-credit as important as technology. • Scrutinize the potential of biotechnology.
Identify and influence unsustainable consumption patterns • Food basket needs to achieve food and nutritional security – calories alone is not enough – micro-nutrient deficiencies are crucial in developing countries, and increasingly obesity too. • What policy tools are available?
Identify minimum ecological service criteria • Understand environmental goods and services produced by ecosystems. • Assess water requirements to sustain these. • Co-manage water for agriculture and ecosystems. • As IUCN says: environmental flows – a negotiated approach.
Identify unsustainable agricultural subsidies and trade barriers • Importance of virtual water will grow. • WTO negotiations should take into account impact on trade in virtual water. • Agricultural subsidies and trade barriers are affecting trade – reducing them will have far reaching impacts on where food is produced and water is used.
