The Food and Agriculture Organization of the United Nations developed the term Climate-Smart Agriculture as an approach to transform agricultural systems to support development and ensure food security in a changing climate. This paper analyses whether climate-smart agriculture policy meets the demands of climate justice and respects the rights of smallholders; and if not, how it could be amended. The study is based on a literature review supplemented by four interviews with climate-smart agriculture actors from diverse backgrounds: a consultant, a small-holder farmer, a practitioner, and a scientist. To examine the climate-smart agriculture concept and its implementation, the following ethical positions are considered: maximalist, minimalist, Pogge ́s intermediate position, Nussbaum's capability approach, Kantian, and Altruist. The study finds that current climate-smart agriculture approaches are not being fairly implemented because there is the unjust sharing of benefits of income and burdens of emission reduction costs, among smallholders and agro-industries. According to the principles of climate justice, this sharing proportion should be equally distributed based on an individual's capacities and poverty should be taken into consideration as well. Climate-smart agriculture should be fair for the farmers; it should not only push and promote agribusiness expansion. The power of multinational corporations has substantially altered global agrifood chains to the detriment of small farmers and the environment. The mandatory inclusion of local, regional and national level civil society organisations and networks holds the potential for a more fair implementation of climate-smart agriculture. Climate-smart agriculture policy could be more successfully implemented if state and non-state/private sector actors would support such collaboration, allowing for decision making at local levels and a deep and honest reflection on development narratives.
