Humanity has reached a planetary saturation

point

The Human ability to do has vastly outstripped our

ability to understand

A resilient biosphere the basis for humen

development

Fierce urgency of now

A great transformation to global sustainability

necessary, possible, and desirable

Goal 1: Ending Extreme Poverty

Goal 2: Achieving Development within Planetary Boundaries

Goal 3: Achieve Gender Equality, Human Rights and the Rule of Law

Goal 4: Achieving Food Security and Rural Prosperity

Goal 5: Empowering Inclusive, Productive and Resilient Cities

Goal 6: Achieving Health and Wellbeing at all Ages

Goal 7: Ensure Effective Learning for Every Child for Life and Livelihood

Goal 8: Curbing Human-Induced Climate Change

Goal 9: Securing Ecosystem Services and Biodiversity

Goal 10: Transforming Governance for Sustainable Development

Operationalising a Paradigm Shift

Elements of a Paradigm Shift

• Integrated reform of irrigated and rainfed agriculture (participation; watershed management; blue-green integration)

• Nexus approach to land-water-ecosystems; agriculture-energy-water

• Landscape and water restoration• Rural water and sanitation – resource reuse• Water and wastewater use • Integated land, water ecoystem management• Institution reform (national water framework)

IrrigatedRainfed

A triply Green Revolution– 2-3 X production– Social-Ecological Resilience– Green water management

Meeting the Global food challenge

Strategies to upgrade rainfed agriculture

• Increase Crop water uptake capaciy

• Increase Crop water Availability

Feeding the world in the Anthropocene within a safe operating space of Planetary Boundaries requires a major global transformation of Agriculture

Sustainable Intensification for food security and rural prosperity the only possible strategy

TitleOur vision:

A world in which agriculture thrives within vibrant ecosystems, where communities have higher incomes, improved food security and the ability to continuously improve their lives
