French Scientific Committee on DesertificationThe creation in 1997 of the French Scientific Committee onDesertification (CSFD) has met two concerns of the Ministries incharge of the United Nations Convention to Combat Desertification.First, CSFD materializes the will to involve the French scientificcommunity versed in desertification, land degradation, anddevelopment of arid, semi-arid and sub-humid areas, in generatingknowledge as well as guiding and advising the policy makers andactors associated in this combat. Its other aim is to strengthen theposition of this French community within the international context.In order to meet such expectations, CSFD is meant to be a drivingforce regarding analysis and assessment, prediction and monitoring,information and promotion. Within French delegations, CSFD alsotakes part in the various statutory meetings of the organs of the UnitedNations Convention to Combat Desertification: Conference of theParties (CoP), Committee on Science and Technology (CST),Committee for the Review of the Implementation of the Convention.It also participates in meetings of European and international scope.CSFD includes a score of members and a President, who are appointedintuitu personae by the Ministry for Higher Education and Research,and come from various specialities of the main relevant institutionsand universities. CSFD is managed and hosted by the AgropolisInternational Association that gathers, in the French town ofMontpellier and Languedoc-Roussillon region, a large scientificcommunity specialised in agriculture, food and environment oftropical and Mediterranean countries. The Committee acts as anindependent advisory organ; it has neither decision-making powersnor legal status.Its operating budget is financed by subsidies from the FrenchMinistries of Foreign and European Affairs and for Ecology andSustainable Planning and Development as well as the FrenchDevelopment Agency. CSFD members participate voluntarily to itsactivities, as a contribution from the Ministry for Higher Educationand Research.More about CSFD:www.csf-desertification.org

Long considered as a localproblem, desertification is now a global issue that affectsus all, including scientists, decision-makers, citizensfrom both the South and North. Within this setting, it isurgent to boost the awareness of civil society to convinceit to get involved. People must first be given the elementsnecessary to better understand the desertificationphenomenon and the concerns. Everyone should haveaccess to relevant scientific knowledge in a readilyunderstandable language and format. Within this scope,the French Scientific Committee on Desertification hasdecided to launch a new series entitled'Les dossiersthématiques du CSFD', which is designed to providesound scientific information on desertification, itsimplications and stakes. This series is intended forpolicy makers and advisers from the North and South,in addition to the general public and scientific journalistsinvolved in development and the environment. It alsoaims at providing teachers, trainers and trainees withadditional information on various associated fields.Lastly, it endeavours to help disseminate knowledge onthe combat against desertification, land degradation,and poverty to stakeholders such as representativesof professional, nongovernmental, and internationalsolidarity organisations.
A dozen reports are devoted to different themes suchas global public good, remote sensing, wind erosion,agroecology, pastoralism, etc, in order to take stock ofcurrent knowledge on these various subjects. The goalis also to set out ideological and new concept debates,including controversial issues; to expound widely usedmethodologies and results derived from a number ofprojects; and lastly to supply operational and intellectualreferences, addresses and useful websites.
These reports are to be broadly circulated, especiallywithin the countries most affected by desertification,by e-mail (upon request), through our website, andin print. Your feedback and suggestions will be muchappreciated! Editing, production and distribution of'Les dossiers thématiques du CSFD'are fully supportedby this Committee thanks to the backing of relevantFrench Ministries and the French Development Agency.The opinions expressed in these reports are endorsed bythe Committee.

Restoring Natural Capital in Arid and Semiarid Regions
Henvironmepollution emission due to the frantic tapping of theseresources are higher than the renewal and absorptionrate ofecosystems. Humanity, for the first time in itshistory, is devouring these reserves, which in turn isgiving rise to tightly linked ecological and humanitariancrises worldwide.An ecological crisis arising from an economic systemThe ecological crisis mainly involves loss ofbio-diversity, shrinkage of natural areas and degradationofecosystem functionality on local, regional andglobal scales (MEA, 2003). The new environmentalconditions created by this crisis have especially led toglobal warming and a reduction in readily accessibledrinking water (Vitouseket al.,1997; Wackernageletal., 2002).It is currently acknowledged that humans—via theeconomic, social and cultural systems and structuresto which they belong—are accountable for thisdegradation (Makhlouf, 1995), despite the directimpacts on humankind, including the worsening ofconflicts for resource access and the loss of naturalgoods and services (e.g. wood supplies, carbonsequestration, etc.). These goods and services providedby ecosystems are nevertheless essential for societies’survival and development. The ways we utilize anddistribute natural resources therefore have to bereshaped.In the current demographic and economic setting,preservation of natural resources alone is not enoughto fulfil humans’ fundamental needs for goods andservices.

However, it will befutile if such initiatives are not combined with settingup sustainable resource exploitation systems and ifour consumption habits are not thoroughly modified(Aronsonet al., 2007a). Experience has shown thatrestoration projects are bound to fail if they are notfocused also on rectifying the ways resources areutilized, i.e. the renewed resources will be overtappedand again degraded since the initial causes still persist(Makhlouf, 1995).In arid and semiarid regions, land degradationdue to overuse is often the result of the insecuresocioeconomic conditions that prevail—meeting thebasic food needs of humans and livestock herds is aprime concern.The humanitarian crisis: biosphere degradation dealsa heavy blow to the poorest peopleNatural goods and services are currently exploited anddistributed at the expense of the poorest populationgroups (MEA, 2005). The resulting unfair distributionof profits further accelerates massive ecosystemdegradation. The poorest people are often obliged touse highly environmentally destructive practices to
