In October 2008 there was an international workshop on this topic, held in Bangkok and sponsored by the Netherlands Development Organisation (SNV).

Several past Ashden Award winners were at the workshop, including:

• Grameen Shakti
• SKG Sangha
• BSP Nepal
  

The proceedings, hosted by the HEDON website, are now available, click here to download them.

The conclusion notes that the provision of transparent and direct financial incentives to rural farmers is a key factor in the uptake of biogas plants in SNV projects, where the finance is only available for plants that meet the required quality standards. The provision of subsidies and/or credit specifically for biogas plants is needed because they don't offer a way of earning income, but instead offer the user a chance to reduce costs, so allowing them to afford to repay the money loaned.
