Threats to Biodiversity io Arab Countries
s~Aj.i~ Samir I. Ghabbour
Abstract
Very linle thought has been given to threats facing biodiversity in the hot
arid regions of the world. llus type of cnvuonmcnt prevails m the largest part
of Arab countries, giving the false impression tha~ their b1ocLvers1ty must be
unimportant. Some people even say: "What IS mere lO deserts that is worth
conserving?". Nevertheless. many plant and arumal domcst1ca11ons took place
in Arab countries and many of the wild relatives of domesticated species still
exist in their centres of origin m semi-desert ;;.re.as However, these arc
gradually disappearing as a result of excessive resoJrce cxplo1tat1on. There arc
also substantial forests still remaining on the fnngas of the Arab World that arc
threatened with rapid destruction Many desert plants have mcd1cmal properties
that give them a high com.men.:1al value, the reason for their uncontrolled
collection by trad1t1onal herbalists. who know very well how to use them
Much less known is the extra--0rdmary physiolog1lf1 cLvers1ry of small desert

therefore of high potential value for med1cme, such as for the treatment of
diabetes and kidney trouble: Tiiey, too, are collectC(I by foreign phannaceut1cal
companies. but destrucuon of thcir habitats is even a greater threat for their
survival. The most serious threat to larger desert animals 1s the hunung
caravans conducted by West Asians who roam the deserts to shoot everything
on sight. The conservation movement 1s steadily growing. and the press is
trying to alert the public about the damage such erosion of b1ocLvers1ry may
cause to human welfare and to the sustai.nab1hry of development
National and international efforts for the management and conservauon of
b1od1versity in Arab countnc.:s include public awareness through the media..
