The books are works in progress and subject to further editing and lesson additions dependent on future funding. We welcome funding sponsors. This initiative is part of the Sustainable Agriculture Kits for Nepal (SAKNepal) project, generously funded (2014-2017) by the International Development Research Centre (IDRC, Ottawa, Canada) and Global Affairs Canada. You can learn more about SAKNepal by browsing the SAKNepal website or watching a mini-documentary available on YouTube.
