Desertification indicators for the European Mediterranean region. State of the art and possible methodological approaches
Desertification indicators for the European Mediterranean region: state of the art and possible methodological approaches [= Indicatori di desertificazione per il Mediterraneo europeo: stato dell'arte e proposte di metodo]
The Italian Environment Protection Agency (ANPA), and the Desertification Research
Centre at the University of Sassary have worked jointly to provide decision-makers
with an in-depth analysis of the state of the art and methodologies applicable to the
evaluation of the desertification phenomenon.ANPA has promoted this important research activity, within the wider and more
dynamic framework of actions it conducts in the Italian National Committee,
providing its support to the definition and start up of the National Plan to Combat
Desertification and Drought.The complexity of the phenomena and their causes leads to the individuation of a
plurality of “actors” who might take the responsibility to carry out actions aimed at
combating Desertification and Drought.Indicators represent a crucial link in the chain that, from knowledge, leads to taking
decisions and promoting responsible behaviours: starting from an evaluation of the
various, physical, biologic, socio-economic processes that contribute to land
degradation and desertification, the goal is to individuate indicators that might prove
useful in territorial planning and public information activities, and that might be a
suitable answer to the request for direct knowledge of the status and evolution of the
phenomenon, as well as the opportunity to take actions aimed at mitigating and,
above all, preventing the occurrence of the phenomenon
Influenza del regime pluviometrico e delle pratiche agropastorali sull'erosione del suolo
Utilización de indicadores de desertificación en los países del Anexo IV
Por más de un decenio la Comisión Europea ha individualizado en la Desertificación uno de los mayores problemas de Europa meridional. Varios proyectos han contribuido a individualizar y describir los principales procesos de desertificación operantes en la Región, sus causas y sus fuerzas arrastrantes.
Los estudios de los años ’90 apuntaban sobre todo a la comprensión y modelización de los procesos de degradación. A partir de los años ’97 y ’98 se afirma la necesidad de desarrollar un estudio más aplicado y detallado en la individuación de indicadores en tan que instrumentos operativos para el gobierno del territorio, valorizando todos los conocimientos adquiridos.
Este trabajo presenta una síntesis de los desarrollos institucionales y científicos en tema de indicadores de desertificación en los Países del Anexo IV
Ranking desertification indicators using TOPSIS algorithm
Desertification is the result of natural and anthropogenic processes, leading to
degradation or loss of the land’s productivity and complexity. To assess the desertification
status, integrated set of indicators must be identified. Indicators must provide synthetic
information on threshold levels, status and evolution of relevant physical, chemical, biological
and anthropogenic processes. Multi-criteria decision-making (MCDM) is a collection
of methodologies to compare, select, or rank multiple alternatives that involve
incommensurate attributes. Technique for order preference by similarity to ideal solution
(TOPSIS) method is a multiple criteria method to identify solutions from a finite set.
TOPSIS is an algorithm for determining the most preferable choices among the possible
indicators that can be developed. The aim of this paper is to introduce TOPSIS as a
decision-making method for the selection and integration of desertification indicators. The
simulation case study presented here is related to the selection of the best set of indicators
to monitor land degradation by remote sensing in three different countries (Brazil,
Mozambique and Portugal), within the framework defined by the DesertWatch Extension
project
