Spatial Patterns and Regional Specialization of Plantation Crops Across Tropical and Subtropical Regions

Plantation crops represent distinctive agricultural systems characterized by large-scale, monocultural cultivation of cash crops for export rather than local consumption[1][2]. These crops display clear patterns of regional specialization determined by specific climatic requirements, historical colonial legacies, economic structures, and global market integration. Understanding the spatial distribution of plantation agriculture reveals how geographic factors, economic development, and international trade patterns create distinct regional concentrations of specific crops worldwide.

I. Definition and Characteristics of Plantation Crops
