Indicator of Agriculture Vulnerability to Climatic Extremes: A Conceptual Model with Case Study for the Northeast Brazil
2014
The Northeast Brazil (NEB)
is known for its temporal and spatial variability of precipitation. Several
studies have investigated this variability in order to understand the damaging
episodes such as droughts and floods. The phenomenon of drought in the NEB is a
complex topic due to affecting millions of people and being the
object of study in several fields of knowledge. One way to try to argue about
this phenomenon is through the concept of vulnerability. The “operability” of
this broad concept in natural disasters is a complex task. In order to measure
an indicator of vulnerability it is necessary large amount of data from
different areas of knowledge, among which include: meteorology,
socio-environmental, economic, public health, among other areas. The main
objective of this study is to create an index of vulnerability to climate
extremes (drought and flood) for the NEB and to compare this rate with those
found in the scientific literature. The data that will be used in this study
are from ANA (Agencia Nacional das aguas), IBGE (Instituto Brasileiro de
Georgrafia e Estatistica), and Ministry of National integration.
