This paper details the importance of indigenous knowledge systems in developing countries around the world. Farmers, communities and households that live in risky environments, have developed intricate systems of diversification that help secure income and food consumption. An integral part of these systems are the knowledge systems that help households plan for future events and decrease uncertainty. Recently indigenous knowledge systems have been given more attention as their importance is addressed in development projects. Unfortunately acknowledgment and understanding of how knowledge systems are used is still not a basic part of all research. This is especially important in the recent advancement of climate and weather forecasting. Scientific advancements can aid poor countries only if knowledge systems are accessed and understood. Also forecast techniques will not improve welfare if they do not first address what households, farmers and communities need, want and lack.
