“…Key phenological variables are derived from the analysis of FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) data from SPOT-VEGETATION instrument for the period of 1998-2012. The cumulative FAPAR value (CFAPAR) over the growing season is used as an indicator of biomass production, as CFAPAR appears to be a suitable proxy of GPP, biomass production [38,[45][46][47][48][49][50] and of crop yield (e.g., [51][52][53]). The correlation between CFAPAR and the key phenological variables and an indicator of the maximum productivity attained during the growing season is then mapped over the Sahel.…”

“…As population increases and food supplies become more constrained, the need to monitor agricultural production even in the least productive regions will grow (Funk & Brown, 2009;Funk & Budde, 2009). The amount of food produced locally often interacts with global commodity prices to determine the price of food on the market, affecting the ability of millions of poor urban and rural Africans to access food (Brown et al, 2006).…”

“…The studies of Kogan (1997), Unganai and Kogan (1998), and Ramesh et al (2003) concluded that AVHRR NDVI is one of the best tools to monitor/assess the large area agricultural droughts. Wan et al (2004), Knight et al (2006) and Funk et al (2009) used NDVI derived from MODIS to understand the crop stages and long term disasters at finer resolution level. MODIS TERRA provide NDVI at 250 m resolution level from which one can make studies from a particular location point where ever required.…”
