This paper presents: 1. An overview of ecosystem services (ES) and payment for ecosystem services (PES) schemes. 2. Explores which ES are important in northern Ghana and potential PES schemes for the region. 3. Discusses the next steps to supporting an ES valuation and the PES schemes best suited for northern Ghana. Ecosystem Services and PES Schemes The Millennium Ecosystem Assessment defines ecosystem services as the provisioning (e.g., water resources), regulating (e.g., climate regulation, water quality), cultural (e.g., aesthetic), and supporting (e.g., soil formation) benefits that people obtain from ecosystems (Millennium Ecosystem Assessment, 2005). Although there are intrinsic values to ecosystem services, the impact that economic development has on them is usually considered an externality. Payment for ecosystem services (PES) schemes provide a market mechanism to internalize these externalities, so that a monetary cost can be associated with the carbon that would be emitted and the decrease in water quality that would occur. Factors that ensure the viability of a PES are 1) To define ES well so that it can be valued, measured, and monitored, 2) To identify a buyer (e.g., private company or government program), and 3) To identify the provider (e.g., land owner). Ecosystem Services in northern Ghana Northern Ghana and all of Sub-Saharan Africa are among the most vulnerable areas in the world to losses of ES and impacts of global climate change. This is partially due to the seasonal and drought-prone semi-arid climate that forms the transition between savanna and the more arid Sahel region, combined with a growing population dependent on subsistence livelihoods (Sheffield et al. 2014; Herrmann et al. 2005). Currently, two primary reports have been published on ES of northern Ghana. One was compiled by the Ghanaian Ministry of Environment, Science, Technology and Innovation (MESTI) in 2015 and focused on the feasibility of sustainable land and water management activities that could be supported by a PES system. The second was published by Boafo et al. in 2014 and reviewed ES in the rural savanna landscapes of northern Ghana. Using these reports, other studies, and preliminary spatial analysis, we will analyze the most important ES for northern Ghana, to be combined with information from local stakeholders and other experts. This paper reviews a number of ecosystem services: water-based ecosystem services; ecosystem services to support crops, game and fodder; timber and non-timber forest products; regulation of greenhouse gases; and recreation, tourism and biodiversity. 1 Potential PES schemes in northern Ghana While all the ES mentioned above are important for northern Ghana, not all are viable as a PES. For a PES scheme to be viable, there must be a well-defined environmental service, a buyer, a provider, and in many cases, some type of third party regulator. This analysis will review those that are potentially appropriate for PES in northern Ghana (Table 1) based on existing literature and staff expertise. Table 1.
