“…Studies in similar regions show that the livelihoods of the rural poor depend regularly on the use of natural resources and the provision of ecosystem services. They are therefore highly vulnerable to environmental degradation, especially if it limits their ability to sustain their consumption of goods and services over time [56].…”

Environmental history, as a field of analysis and transdisciplinary study, aims to explore the interactions between society and ecosystems from a deep understanding of how relationships between human groups and natural systems change over defined periods of time. This article seeks to delve into the environmental history of the savannahs of the Cesar department in Colombia, documenting the milestones in the privatization of the commons and the degradation of social–ecological systems. Methodologically, satellite images and aerial photographs are analyzed to determine the changes in land cover that reveal the state of the ecosystems, and an ethnographic approach is used to document the perception and valuation of local Afro-descendant communities in the region. The article shows how, over the last 60 years, land-use planning models have favored individual appropriation practices and agroindustrial models over collective forms of pastoralism and small-scale agrifood systems. It also documents the main socio-ecological impacts and the conflicts implicit in different tenure models that should be taken into account in the various public policies related to sustainability, peace building, and the recognition of territorial rights in the Colombian Caribbean.

The Cienaga Grande de Santa Marta Ramsar Site (CGSM) is the most important Caribbean estuarine wetland in Colombia. The site represents a strategically important ecosystem supporting the national and local economy. However, their ability to provide ecosystem services has been seriously affected mainly due to changes in land use, disturbances of water flows, man-made climate change and interannual climatic variability. These circumstances led to its inclusion in the Montreux Record, a register of wetland sites on the ‘List of Wetlands of International Importance’ where variations in ecological character have happened, are happening or are likely to happen as an outcome of technological developments, pollution or other human interference. This paper presents the first account of marine and coastal ecosystems developed in Colombia at the Cienaga Grande de Santa Marta. Following the principles for ecosystem accounting of the System of Environmental-Economic Accounting—Ecosystem Accounting (SEEA EA), we developed accounting tables of extent and condition of ecosystems, biophysical and monetary flows of climate regulation and fishing supply and the monetary account of ecosystem assets. Results of the ecosystem account allow visualising the importance of ecosystem services of the wetland, its capacity to provide economic benefits, social welfare and livelihoods at local and national level. Finally, we identify main gaps of information, highlight the applicability of ecosystem accounting to policy- and decision-making on economic and environmental issues and evaluate the challenges to implement it.
