In this context, there are many potential adaptation options available for a marginal change of existing agricultural and other livelihood systems, often variations of existing climate risk management. According to Howden et al. , implementation of these options is likely to have substantial benefits under moderate climate change for some existing cropping systems. Apparently, there are limits to their effectiveness under more severe climate changes. Hence, more systemic changes in resource allocation need to be considered, such as targeted diversification of production systems and livelihoods. Howden et al.  further argue that achieving increased adaptation action will necessitate integration of climate change-related issues with other risk factors, which implies integrating non-climatic factors, such as climate variability and market risk, and with other policy domains, such as sustainable development. An increasing number of research programmes seek to support adaptation to climate change through the engagement of large-scale transdisciplinary networks that span countries and continents .
