This report summarizes fieldwork done by members of the REAL project who are studying wetlands across Kenya to understand how these systems have evolved through time. We employ sedimentological and palaeoecological approaches to physically characterise the wetland basins and to gain a deeper understanding of how these wetlands have changed in response to past variability of climate and human land use practices. Multiple wetlands exist within the Mau Forests of Kenya that are ecologically and developmentally important to the region. Hydrologically, these swamps form significant surficial reservoirs of water that drain into extensive channel networks across East Africa and are an important component of the high elevation ‘water towers’ that are crucial to water management and the political imagining of nationally-important water resources. Historically, these wetlands have been key landscape features serving wildlife, livestock, and human populations with water particularly during dry periods. Few paleoenvironmental studies have been produced on the Mau Escarpment. The purpose of this study is to investigate these wetlands and examine how these ecosystems have responded to Late Quaternary climatic variability, large wildlife herbivory, and changes in human land use patterns. Continued scientific study is needed due to the diversity of wetland ecosystems across this landscape with strong environmental gradients and to analyse the varying spatial controls influencing the environmental conditions. This is especially true considering the multiple, recent, rapid and intense landscape transformations that have occurred. Some of these transformations include the industrial management of plantation forests, channelisation of wetlands, sediment infilling, road construction, increasing human populations, and conversion of forest to farmland. This document reports ongoing scientific study of the physical wetland systems and how the sites have evolved over geological time scales in response to climatic and land-use behavioural changes.

This report summarizes fieldwork done by members of the REAL project who are studying wetlands in Kajiado District, southern Kenya, to understand how these systems have evolved through time. We employ sedimentological and palaeoecological approaches to physically characterise the swamp basins and to gain a deeper understanding of how these swamps have changed in response to past variability of climate and human land use practices. Multiple wetlands exist upon the semi-arid landscape of southern Kenya within the boundaries of the previous extent of Amboseli Lake that are ecologically and developmentally important to the region. Hydrologically, these swamps are recharged through groundwater flows from Mt Kilimanjaro, which are sensitive to climatic change and extraction pressure by nearby populations. Historically, these wetlands have been key landscape features serving wildlife, livestock, and human populations with water particularly during droughts. The multiple stakeholders within the area have vested and often competing interests regarding how these critical ecosystems should be managed in a sustainable framework for the future of these communities. Previous studies have shown that these wetlands are sensitive to late Holocene climatic variability, large wildlife herbivory, and changes in human land use patterns. Continued scientific study is needed due to the diversity of wetland ecosystems across this landscape and varying spatial controls influencing the environmental conditions. This is especially true considering the multiple, recent, rapid and intense landscape transformations that have occurred. Some of these transformations include the creation of societal and physical enclosures around wetlands, increasing human population, land subdivisions and tenure changes, fluctuations within the conservation and tourism industry, drainage for conversion to croplands and increases in irrigated agriculture wildlife and livestock population changes in the Amboseli basin, poaching, and declining wet montane forest cover on the slopes of Mt Kilimanjaro, Tanzania. This document reports ongoing scientific study of the physical wetland systems and how the sites have evolved over geological time scales in response to climatic and land-use behavioural changes.

Human use of fire on the landscape has influenced vegetation composition, biomass abundance, and biodiversity in many ecosystems worldwide. Fire activity also has implications for carbon cycling and can result in a net carbon sink or source depending on the alteration of fire regimes and vegetation changes. The major controls of fire activity over centennial to millennial scales are dynamic and are further influenced by human land use and behavioral patterns and have shaped the modern ecosystems. It is often difficult to quantify the anthropogenic influence on biomass burning because the relative importance of natural controls of fire vary over multiple spatiotemporal scales and the analysis of detailed paleoecological data and human cultural information is necessary. Land use and burning practices have changed throughout the Holocene in East Africa and over the coming months we will be synthesizing multiple palaeoecological records of vegetation and fire activity to begin to disentangle the human influences on the environment. Modern biomass burning activity and rapid vegetation changes will be quantified using moderate-resolution imaging spectroradiometer (MODIS) land cover grids (500-m resolution).
Multiple records of biomass burning activity are needed to understand the natural controls on fire, such as climate, fuel types and abundance, and topography. The rise of pastoralist societies around 4000 cal yr BP represented a major shift in human impacts on vegetation, fuels, and ignition patterns. By analyzing the natural variability alongside archeological and historical data on human societies it may be possible to characterize the ecological impacts of human burning activities.
Demographic changes impacted the environment variably over space and reflected the intensity of land use and the values of those societies. Synthesis of multiple records of biomass burning can be used to understand the broad-scale controls of fire activity. Comparative analysis of fire records at sites across environmental gradients provides insights into the relative importance of natural and anthropogenic controls of fire. Examination of natural and anthropogenic variability on vegetation and disturbance regimes helps us understand the evolution of human-environmental interactions and the processes that have led to the present landscapes. This information is critical to developing sustainable trajectories for land management policy and conservation efforts crucial to the future of East African landscapes experiencing development pressure and rapid climate change.
