Which plains are important agricultural regions in Morocco?

Morocco’s coastal plains and plateaus are the primary centers for the country's modern commercial agriculture. Several key regions are particularly important for their agricultural productivity:1

• Gharb Plain: Located in the northwest, this major alluvial plain is a significant citrus-growing region.23
• Chaouïa, Doukkala, and Abda Plains: Situated south of Casablanca, these plains feature tirs (dark clay-marl) soil, which is highly productive for wheat and barley when moisture levels are sufficient.43
• Saïs Plain: Surrounding the cities of Fès and Meknès, this region is characterized by hamri soil, which supports productive vineyards and cereal crops.43
• Tadla and Haouz Plains: Located in the interior, these are key high plains that contribute to the agricultural output of the Moroccan Plateau.3
• Sous River Valley: Positioned between the High Atlas and Anti-Atlas ranges, this fertile alluvial basin is a vital agricultural area where fruits, vegetables, cotton, sugar, and olives are cultivated, often for export.35

These regions benefit from diverse soil types, such as the silt-rich dhess found in the Sebou basin, which serves as a foundation for much of the country's irrigated agriculture.4
