A Degrowth Scenario

This document discusses a hypothetical government scenario aimed at minimizing throughput by abandoning non-renewable extraction and optimizing agricultural technologies. It presents various water policy options to address the challenges posed by finite freshwater resources and local depletion. Key aspects include the relationship between sustainability and yield, the ecological footprint of different crops, and the importance of biodiversity. It emphasizes the need for effective, politically feasible policies that promote civil society participation and long-term solutions in agricultural and water resource management.

Presentation Transcript

  1. A Degrowth Scenario Hypothetical Government Minimize throughput Abandon non-renewable extraction Agricultural Technology Options Kealan Gell Agricultural Engineering, Wageningen University, Netherlands Water Policy Options Katherine Trajan Water Policy, Oxford University, England

  2. Agricultural Technology Define: Sustainability and Yield Medium Soil quality, biology, cover Use of waste Water retention Yield? Sustainability?

  3. Work Inputs – Machines, labour Yield ? Sustainability?

  4. 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)

  5. Use of Crops: Ecological Footprint, Current Biomass Flows, Adequate standard of life?

  6. Line represents theoretical maximum yield of 10 t dm/ ha

  7. 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

  8. Different policies can achieve the same objective The most effective policies are the least politically feasible A combination of policies is less offensive than a single regulation Produce National Resource Accounts Civil Society Participation Identify unique management options Interested in long-term solution Increase awareness Improve effectiveness Increase transparency
