With current scenarios from the CBD, all regions of the world spective Unit (2008), at present 228 million ha of arable land
will continue to experience loss in biodiversity, with Africa, are in use in Sub-Saharan Africa. Potentially, this area can be
followed by Latin America and the Caribbean, experiencing increased to over 1 billion ha of suitable land for rainfed crops
the highest losses as a result of major land use changes (es- in Africa by 2030. Likewise, in South America similar sce-
pecially in increases in pastures and biofuel production) com- narios project the present 208 million ha in agricultural use
bined with increasing land degradation. Large areas of Africa to be increased to over 1 billion ha by 2030 at the expense of
are projected to lose more than 25% of mean species abun- natural ecosystems. These expansions will have huge costs to
dance by 2050 (UNEP, 2007). According to FAO’s Global Per- biodiversity.
