Agroforestry as an old approach to a new challenge of combating climate change: a critical analysis of the cocoa sector

Abstract Climate change is the greatest challenge to developing countries, especially where rain-fed agriculture is the main source of livelihood and revenue. Agroforestry provides an opportunity for farmers to adapt and reduce the carbon footprint. We conducted an exploratory review on the role of cocoa agroforestry for climate change mitigation and adaptation of smallholders by applying combinations of keywords that include climate change, agroforestry, stakeholders, Paris agreement, INDCs/NDCs, mitigation and adaptation. The paper combined data sources covering reports on past and on-going cocoa sustainability projects and policy interventions in Ghana as well as the output of exploratory review that utilized relevant key words to identify appropriate literature for investigation and analysis. We established that, there is low adoption of pro-environmental interventions introduced by both Government and NGOs in the cocoa sector. In addition, there is a shift in cocoa farming from expansion into forest areas to adoption of intensive cocoa monoculture. Despite the importance of shaded trees in cocoa production such as the benefits gained from agroforestry system, cocoa farmers have low appreciation of their environmental, soil, nutrients and other ecological benefits. We recommend that cocoa farmers should be involved in the formulation and implementation of pro-environmental interventions that affect their cocoa production practices. This will make farmers take ownership of the innovation instead of it being introduced to them. In addition, since our review of the literature established that the surge in yield is the impetus for cocoa monoculture adoption, there is the need to introduce cocoa varieties with higher yields under agroforestry system. Finally, there should be monetary valuation of shade trees used in cocoa agroforestry systems for payment to farmers to help improve agroforestry adoption. We argue that cocoa agroforestry though considered an old practice, remains one of the most appropriate land-use systems that is climate-smart with great potential to contribute to sustainable cocoa production.
