Agricultural Technology
Define: Sustainability and Yield
MediumSoil quality, biology, coverUse of wasteWater retentionYield?Sustainability?
Work Inputs – Machines, labour Yield ? Sustainability?
Choice of Crops• Biodiversity
– Yield?– Sustainability?
• Yield– 20t dm/ha tropical NPP– 8-15t dm/ha root crops– 10t dm/ha temperate NPP– 5t dm/ha fruit– 3t dm/ha US maize– 0.8t dm/ha India no irrigation(FAOSTAT)
Use of Crops: Ecological Footprint, Current Biomass Flows, Adequate standard of life?
Line represents theoretical maximum yield of 10 t dm/ ha
Water Policy Options
Fresh water is a finite resource
It keeps us alive
It is over-exploited
Local depletion does and will continue to occur
Supply augmentation options are limited
The “somewhere else” to get water from is getting harder to find
1. Different policies can achieve the same objective2. The most effective policies are the least politically
feasible3. A combination of policies is less offensive than a
single regulation4. Produce National Resource Accounts5. Civil Society Participation
1. Identify unique management options2. Interested in long-term solution3. Increase awareness4. Improve effectiveness5. Increase transparency
