Organic agriculture is a holistic production management which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles and soil biological activity. It emphasis the use of management practices in preference to the use of off-farm inputs, taking into account conditions requiring locally adapted systems. Organic agriculture is not only a specific agricultural production system, it is also a systematic and encompassing approach to sustainable livelihoods in general, where due account is given to relevant factors of influence for sustainable development and vulnerability, be this on physical, economic or socio-cultural levels. Organic agriculture has a long tradition as a farming system and it has been adapted for many climatic zones and local conditions. Again, it is a recognized potential as a development strategy for rural communities. It reduces the vulnerability of the farmers to climate change and variability. Organic agriculture comprises highly diverse farming systems and this increases the diversity of income sources and the flexibility to cope with adverse effects of climate change and variability such as changed rainfall patterns. This lead to higher economic and ecological stability through optimized ecological balance and risk-spreading. Organic agriculture is an adaptation strategy that can be targeted at improving the livelihoods of rural populations and those parts of communities that are vulnerable to adverse effects of climate change and variability.
