Lessons to be learned in adoption of autonomous equipment for field crops
Autonomous equipment for crop production is on the verge of technical and economic feasibility, but government regulation may slow its adoption. Key regulatory issues include requirements for on-site human supervision, liability for autonomous machine error, and intellectual property in robotic learning. As an example of the impact of regulation on the economic benefits of autonomous crop equipment, analysis from the United Kingdom suggests that requiring 100% on-site human supervision almost wipes out the economic benefits of autonomous crop equipment for small and medium farms and increases the economies-of-scale advantage of larger farms.
Cap-and-trade of water rights: A sustainable way out of Australia's rural water problems?
Trading water rights is a tool for re-allocation of water resources in water-scarce regions such as Australia. Tradable water rights help farmers to act flexibly when facing high fluctuations in water availability and to use the water in a sustainable and environmentally friendly manner. A precondition is that the quantity of water rights is capped at an appropriate level. The institutional arrangements and market structures in which water-right trading is embedded are key factors for the success of such water management instruments. By analysing the structure of the water-right market and water caps as well as using results from explorative expert interviews, the article sheds light on potential problems with the Australian cap-and-trade scheme concerning sustainable water usage. It also asks whether the Australian scheme provides lessons to be learnt by other countries facing similar problems.
