Livelihood Security: Climate change, conflict and migration in - UNEP

Livelihood security Livelihood security refers to the absence of objective threats to livelihood
preservation and/or subjective fears that livelihood preservation may be
undermined. It requires maintaining the conditions under which each
livelihood group can live from their activities. (UNEP, 2011)
Migration A process of moving, either across an international border, or within a state.
It is a population movement, encompassing any kind of movement of
people, whatever its length, composition and causes; it includes migration
of refugees, displaced persons, uprooted people, and economic migrants.
(IOM, 2004)
Natural resources Natural resources are actual or potential sources of wealth that occur in a
natural state, such as timber, water, fertile land, wildlife, minerals, metals,
stones, and hydrocarbons. A natural resource qualifies as a renewable
resource if it is replenished by natural processes at a rate comparable
to its rate of consumption by human or other users. A natural resource
is considered non-renewable when it exists in a fixed amount, or when
it cannot be regenerated on a scale comparable with its consumption.
(UNEP, 2009)
Resilience The ability of a social or ecological system to absorb disturbances while
retaining the same basic structure and ways of functioning, the capacity for
self-organization, and the capacity to adapt to stress and change. (IPCC,
2007)
Scarcity Scarcity describes a situation where renewable resources – such as water,
forests or productive land – are degraded or decreasing, in the sense that
the resource is used faster than it is replenished. (UNEP, 2011)
Vulnerability Vulnerability is the degree to which a system is susceptible to, and unable to
cope with, adverse effects of climate change, including climate variability
and extremes. Vulnerability is a function of the character, magnitude, and
rate of climate change and variation to which a system is exposed, its
sensitivity and its adaptive capacity. (IPCC, 2007)
