The agricultural sector plays a critical role in food security, poverty reduction and economic growth, especially in developing countries, where agriculture is fundamental to sustainable development. As part of International Institute for Sustainable Development’s Food Security and Climate Change Initiative, this paper provides an overview of the potential options for increasing smallholder agriculturalists’ access to financing that will help them achieve the triple dividend of enhanced food security, increased resilience to climate change and reduced emissions of greenhouse gases (GHGs). It concludes by providing a number of suggestions for mobilising additional investment that will enable further progress towards the realisation of a ‘triple benefit’ in agriculture activities, with a particular focus on the unique needs of smallholders.
