Plants play an e.se.tial role.in m.tte. and e.e.gy transform.tions and are.ke. m.0}se.ge.s in the.carbon and e.e.gy cycle. Ne. prim.ry productivity (NPP) re.le.ts the.capability of plants to transform.solar e.e.gy into photosynthe.is. It is ve.y se.sible.for factors affe.ting on ve.e.ation variability such as clim.te. soils, plant characte.istics and hum.n activitie.. So, it can be.use. as an indicator of actual and pote.tial tre.d of ve.e.ation. In this study we.use. the.actual NPP which was de.ive. from.m.DIS to asse.s the.re.ponse.of NPP to clim.te.variable. in Gadarif State. from.2000 to 2010.
