Understanding Human-Environment Interaction In Ancient Mongolia
- Lisa Jazz
Mongolia
- Btw Russian Federation and People’s Republic of China
- Climate: harsh extreme (-40 in winter to 100 in summer)
> Dramatic change - Population: 10 years ago 30% lives in cities > increase now
Agriculturalists, herders, and hunter-gatherers in East Asia
- Nomadic Pastoralists (beginning 3300 BC)
- Moving settlements seasonally (1-2 times / yr)
- Domesticated wheat + barley
- Domesticated cattle, sheep, goats, horses
- Milk + milk products
- Wild sheep, goats, gazelle, deer, rabbits, birds, fish
- Wild fruits, nuts, grains + tubers
- Gobi Desert Hunter-Gatherers (until 1500 BC)
- Moving settlements regularly
- Wild horses, cattle, deer, sheep, goats, gazelle
- Wild rabbits, birds, frogs ?
- Wild greens, fruits, nuts, grains + tubers
- Wild grass seeds
- Agriculturalists (beginning 6000BC)
- Large settlements in 1 place
- Domesticated millet + rice
- Domesticated pigs + chicken
- Wild cattle, gazelle, deer, rabbits, birds, fish
- Wild fruits, nuts, grains + tubers
> Know the environment > Diet choice + eating habit
Gobi-Steppe Neolithic Project
- Excavation include: burials, habitation sites
- Aim: how human adapt to environment change + how human change the environment as well
Mongolian Neolithic
Period | Dates | Tech | Land-use
Oasis 1 | 11500-6000BC | Pottery after 7700BC, microblades | High residential mobility, increasing use of wetlands
Oasis 2 | 6000-3000BC | Pottery, Microblades, grinding stones | Wetland-centric, logistic mobility
Oasis 3 / Bronze Age | 3000-1000BC | Pottery, microblades, bifaces, polished axes | Wetland-centric, mixed mobility?
Pleistocence (Ice Age) Ecosystems
- 2.5 million to 11700 years ago
- Fluctuation of climate since 120,000 years ago
- Mammoth, giant beaver, Irish elk
- Africa: covered by grassland > human = part of the grasslands (in the ecosystem)
Holocene (Post-Glacial) Ecosystems
- 11700 years ago to present
- Wetlands
> Change types of food ppl ate
Human environmental impacts
- Wild fire
- Harvesting (e.g. wild rice)
- Human produce garbage for raccoons to eat
- Landscape engineering: the intentional way human modifying lands
(E.g. coastal California landscapes were created by fire to suit the needs of indigenous hunter-gatherers; Australian indigenous gps use fire to improve environmental carrying capacity)
Anthropogenic (human modified) Landscapes
-
Human and landscape palaeoecology
3 important methods:
- Geoarchaeology
- Species identification
- Ecological modeling
Geoarchaeology
- Stratigraphy and soil types (e.g. river cut, wet-dry cycles)
- Dating sediments
- Microbotanical remains
- Mapping landforms
Zooarchaeology and Palaeoethnobotany
- Species (taxonomic) list (e.g. hare bones, grass seeds)
- Species identification
- Taphonomy
- Weights and counts
- In dry cave, only burned seeds can survive
GIS-Based Ecological Modelling
- Compiling NASA satellite imagery
- Creating GIS-based hydrological models
- Modelling species interactions (community ecology)
- Modelling species distributions (MaxEnt)
- Refining models based on field tests
- Mapping on archaeological data
* Many of them based on hydrology
Site: Zaraa Uul
- Getting bones in this landscape > Hunting animals that are extinct today > Suggest the environment is different > Wetlands + grasslands > grasslands > ? Former lake basin at Zaraa Uul > compared to HUla wetlands in Israel

***Site formation (VERY IMPORTANT!!)
= Product of: 1. Material deposited: A. Type of material B. Process of deposition - accidental, e.g. loss - intentional, e.g. burial or trash 2. Environment A. Climatic variables - Acidic, e.g. NE Woodlands - Arid, e.g. American SW; highland Andes - Wet, e.g. Submerged, frozen B. Depositional setting
Depositional environments
- Non-depositional (e.g. lakeshore)
- “Accretions” (e.g. rockshelter)
- Alluvial (e.g. floodplain)
- Non-deposition environment
Non-depositional (e.g. lakeshore)
E.g. typical non-depositional sole profile
- “O” horizon 0-5cm below ground surface = zone of organic (dark)
- “A” horizon 5-15cm = zone of leaching, organic breakdown
- “B” horizon 15-38cm = zone of accumulation, chemical alteration
> Iron ores (Colors)
- “C” horizon >38cm = zone of inactive sediment, “parent material”
> Most of the things wont get burial in depth > close to surface
> <10% artifact distribution 40cm below the ground surface
- Fire-cracked rock: heat up the rocks > put into water > rocks crack > disposal
- Postholes > how ppl are organized
- Accretional
Accretional (e.g. rockshelter)
- Little separation btw occupation
- Alluvial
Alluvial (e.g. floodplain)
- Winooski - Burlington bridge @1928 taken by a flood
- Anthropogenic: generally made by human / human activities
> e.g. dark lines in btw light soils layers > human activities
- Site: Milo, Maine, perfect floodplain per 5 hundred years
- Better preservation: preserved by sand layers
- Site Howe Farm, Winooski River Intervale: Logs down > erosion
