Environmental archaeology is a sub-discipline of archaeology which emerged in the 1970s<ref>Template:Cite journal</ref> and seeks to use archaeological data to reconstruct the relationships between past societies and the environments they lived in.<ref>Template:Cite web</ref><ref>Template:Cite book</ref> It utilizes approaches from paleoecology to study past environments through the methods of human paleoecology and other geosciences. Reconstructing past environments and past peoples' relationships and interactions with the landscapes they inhabited provides archaeologists with insights into the origins and evolution of anthropogenic environments and human systems. This includes subjects such as prehistoric lifestyle adaptations to change and how economic practices have affected the environment.<ref>Template:Cite book</ref>

Environmental archaeology is commonly divided into three sub-fields:

Environmental archaeology often involves studying plant and animal remains in order to investigate which plant and animal species were present at the time of past habitations, and how past societies managed and interacted with them. It may also involve studying the physical environment and how similar or different it was in the past compared to the present day. An important component of such analyses represents the study of site formation processes.<ref>Template:Cite web</ref>

This field is particularly relevant when artifacts may be absent from an excavated or surveyed site, or in cases of earth movement, such as erosion, which may have buried artifacts and archaeological features. While specialist sub-fields, for example bioarchaeology or geomorphology, are defined by the materials they study, the term "environmental" is used as a general template in order to denote a general field of scientific inquiry that is applicable across time periods and geographical regions studied by archaeology as a whole.<ref>Template:Cite journal</ref>

Subfields

Archaeobotany

Archaeobotany is the study and interpretation of plant remains. By determining the uses of plants in historical contexts, researchers can reconstruct the diets of past humans, as well as determine their Subsistence economy strategies and plant economy. This provides greater insight into a people's social and cultural behaviors.<ref name=":1">Template:Cite journal</ref> Analysis of specimen like wood charcoal, for example, can reveal the source of fuel or construction for a society. Archaeobotanists also often study seed and fruit remains, along with pollen and starch.<ref>Template:Cite web</ref> Plants can be preserved in a variety of ways, but the most common are carbonization, water logging, mineralization, and desiccation.<ref name=":1" /> A field within archaeobotany is ethnobotany, which looks more specifically at the relationship between plants and humans, and the cultural impacts plants have had and continue to have on human societies. Plant usage as food and as crops or as medicine is of interest, as well the plants' economic influences.<ref>Template:Cite web</ref>

Zooarchaeology

Zooarchaeology is the study and interpretation of animal remains and what these remains can tell us about past human diets, behaviors, and history.<ref name=":0">Template:Cite web</ref> Through the analysis of the physical features of animal remains, evidence of extractive behaviors such as hunting as well as domestication can be demonstrated.<ref name=":0" /> These data are interpreted as a reflection of the changes that humans have caused to the environment, such as the depletion or overharvesting of animal populations over time.<ref>Template:Cite journal</ref> As with other zooarchaeological applications, in environmental archaeology data gathered from faunal analyses can often be either species-specific or involve multi-species analysis.<ref>Template:Cite journal</ref> These primary data are obtained from the excavation of archaeological features, which can include both waste disposal areas as well as items made from modified animal materials.<ref name=":0" /> Additionally, faunal studies implement biomolecular methods such as stable isotopes, Zooarchaeology by Mass Spectrometry (ZooMS), and ancient DNA to provide insight into the lives of past animal populations.<ref>Template:Cite journal</ref> These methods have been leveraged to demonstrate anthropogenic environmental change via overhunting, habitat destruction, and declining genetic diversity.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>

Geoarchaeology

Geoarchaeology is the study of landscape and of geological processes. It looks at environments within the human timeline to determine how past societies may have influenced or been influenced by the environment.<ref name=":3">Template:Cite book</ref> Sediment and soil are often studied because this is where the majority of artifacts are found, but also because natural processes and human behavior can alter the soil and reveal its history.<ref name=":3" /> Apart from visual observation, computer programming and satellite imaging are often employed to reconstruct past landscapes or architecture.<ref name=":42">Template:Cite journal</ref>

Due to the multidisciplinary nature of archaeology in general, the range of research in the earth and environmental sciences, and possibility of methodologies, environmental archaeology has branched and connected with a number of other fields to include numerous cross and subfields such as:<ref>Template:Cite web</ref>

History

Environmental archaeology has emerged as a distinct discipline since the second half of the 20th century.<ref name="Murphy Fuller 2017 pp. 1–10">Template:Cite journal</ref><ref>Template:Cite web</ref> In recent years it has grown rapidly in significance and is now an established component of most excavation projects. The field is multidisciplinary, and environmental archaeologists, as well as palaeoecologists, work side by side with archaeologists and anthropologists specialising in material culture studies in order to achieve a more holistic understanding of past human livelihood and people-environment interactions, especially how climatic stress affected humans and forced them to adapt.<ref>Template:Cite journal</ref>

In archaeology in the 1960s, the environment was seen as having a "passive" interaction with humans. With the inclusion of Darwinism and ecological principles, however, this paradigm began to shift. Prominent theories and principles of the time (oasis theory, catastrophism, and longue duree) emphasized this philosophy. Catastrophism, for instance, discussed how catastrophes like natural disaster could be the determining factor in a society's survival.<ref name=":02">Template:Cite book</ref> The environment could have social, political, and economic impacts on human communities. It became more important for researchers to look at the direct influence the environment could have on a society. This gave rise to middle range theory and the major questions asked by environmental archaeology in the 20th and 21st centuries. Research has since led environmental archaeology to two major conclusions: humanity originated in Africa and agriculture originated in south-west Asia. Another important shift in thinking within the field centered around the notion of cost-effectivity. Before, archaeologists thought that humans usually acted to maximize their use of resources, but have since come to believe that this is not the case. Subsequent theories/principles include sociality and agency, and the focus on relationships between archaeological sites.<ref name=":02"/> Government research audits and the 'commercialisation' of environmental archaeology<ref>Template:Cite journal</ref> have also shaped the sub-discipline in more recent times.<ref>Template:Cite journal</ref>

Methods

Environmental archaeologists approach a site through evaluation and/or excavation. Evaluation seeks to analyze the resources and artifacts given in an area and their potential significance. Excavation takes samples from different layers in the ground and uses a similar strategy to evaluation. The samples typically sought after are human and faunal remains, pollen and spores, wood and charcoal, insects, and even isotopes.<ref>Template:Cite journal</ref> Biomolecules like lipids, proteins, and DNA can be revelatory samples.<ref>Template:Cite book</ref> With respect to geoarchaeology, computer systems for topography and satellites imaging are often used to reconstruct landscapes. The Geographic Information System (GIS) is a computer system that can process spatial data and construct virtual landscapes.<ref name=":42"/> Climate records are able to be reconstructed through paleoclimatology proxies, which can provide information on temperatures, precipitation, vegetation, and other climate-dependent conditions.<ref>Template:Cite web</ref> These proxies can be used to provide context for present climate and compare past climate against the present.<ref>Template:Cite web</ref>

Significance

Each focus within environmental archaeology collects information about a different aspect of humans' relation with their surrounding environment. Together these components (along with methods from other fields) are combined to fully understand a past society's lifestyle and interactions with their environment.<ref> Environmental archaeology: theoretical and practical approaches. Place of publication not identified: Routledge, 2016. </ref> Past aspects of land use, food production, tool use, and occupation patterns can all be established and the knowledge applied to current and future human-environment interactions. Through predation, agriculture, and introduction of foreign biota into new environments, humans have altered past environments. Understanding these past processes can help us pursue conservation and restorative processes in the present.<ref>Template:Cite journal</ref>

Environmental archaeology provides insight on sustainability and why some cultures collapsed while others survived. Societal collapse has occurred many times throughout history, one of the most prominent examples being the Maya civilization. Using lake sediment core and climate reconstruction technology discussed earlier, archaeologists were able to reconstruct the climate present at the time of the Mayans.<ref>Template:Cite web</ref> Although the Yucatán Peninsula was found to have extreme drought at the time Mayan society collapsed, many other factors contributed to their demise. Deforestation, overpopulation, and manipulating wetlands are only a few theories as to why the Maya civilization collapsed, but all of these worked in tandem to negatively impact the environment.<ref>Template:Cite web</ref> From a sustainability perspective, studying how the Mayans impacted the environment allows researchers to see how these changes have permanently affected the landscape and subsequent populations living in the area.<ref>Template:Cite web</ref>

Archaeologists are increasingly under pressure to demonstrate that their work has impact beyond the discipline. This has prompted environmental archaeologists to argue that an understanding of past environmental changes is essential to model future outcomes in areas such as climate change, land cover change, soil health and food security.<ref>Template:Cite journal</ref>
