The accuracy of the CGMS-MAROC’s forecasts is constantly refined, as they depend on four<br />

parameters that are subject to continuous improvement: the historical data available, the number of<br />

meteorological stations covering the country, the availability of an agricultural mask, and the quality<br />

of the NDVI.<br />

The consistency of crop yield forecasting at national level improves as the growing season<br />

progresses (see Figure 3.8 below); the use of different indicators increases its precision<br />

(Table 3.7 below).<br />
