Data for: The Effect of Ownership on Ecosystem Management among Human Foragers

These are supplemental statistical data and the data used to conduct the analysis in the paper The Effect of Ownership on Ecosystem Management among Human Foragers. The variables in the data file Supp_data.csv are defined in the body of the paper (``Data and Methods") and below.

burn=presence of burning defined by Keeley (1995), 0=no burning, 1=burning for animals, 2=burning for plants
burnID=presence or absence of burning, 0=absence.

Sow=presence of planting and tending wild plants defined by Keeley (1995) 0=no planting, 1=planting tobacco/other non-food sources, 2=planting edible species of plant
SowID=presence or absence of planting, 0=absence

Owners=categorical variable of ownership defined by Binford (2001)
1 = no ownership
reported, but associations with a territory may be recognized.

2 = local groups claim exclusive use
rights over resource locations and households may claim exclusive
rights to particular resources (e.g., tree species)

3 =local groups claim ownership over hunting and fishing locations and
these rights are administered by leaders or smaller segments of local
groups (see \citealp[p.~426]{Binford2001}).

4 = Elite ownership of land and resources. In addition,
there may be family claims to particular resource locations. Resource
patches may be owned by a family and can be given away, inherited or
disposed of within the group

OWN=Collapse of the owners variable into 3 categories instead of 4.
0=No ownership
1=corporate ownership
2=Ownership with inheritance

DENSITY=Population density people.sq. km

CVRAIN=Coefficient of variation in rainfall

NPP2=Net primary productivity

Area=Area of ethno-linguistic group in 100 sq. km

Population=Population of an ethno-linguistic group.

War=Level of warfare defined by Binford (2001)

1= No organized competition.
Success in armed conflict is not an accepted male role in the overall life
of the people.
2= Conflict is continually present on an on-again/off-again
basis. Accelerated raiding (i.e., tit-for-tat raiding that becomes
progressively more encompassing) is not a normal condition.
3= Conflict is
more common than in category two and there are unprovoked attacks on
intruders. There is planned and tactically executed raiding on other groups
not necessarily in the context of revenge or feuding.
4= Conflict is common
in the region, but it may flare up to major proportions periodically. Goals
are more commonly to plunder and take land or resources.
5= All the
properties of category four but with the additional feature that such
conflict is sustained and results in long-term expansion of groups at the
expense of others.

War2=The above war variable collapsed into three
ordinal categories:
1= no warfare (corresponding to category 1),
2= low
warfare (corresponding to categories 2 and 3),
3 = high warfare (corresponding to categories 4 and 5).

geodist=mean distance of a group from other groups
avglldist=mean linguistic distance of a group from other groups
