Karst peaks along the Gui (locally Li) River — Guangxi These towering karst formations near Guilin form one of China's most iconic natural landscapes, having long inspired Tang dynasty poets, Song-era painters, and contemporary travelers alike.

In the Guangxi autonomous region, irrigation and terracing are essential strategies for maximizing agricultural productivity in challenging terrain.

Since the 1950s, the government has expanded the region's cultivated land and increased crop yields by implementing extensive irrigation systems, including the construction of dams, canals, and reservoirs to supply water to dry lands. These efforts have been instrumental in helping Guangxi achieve self-sufficiency in rice production.12

Terracing is employed wherever feasible on hillsides to expand the available arable land. This method involves planting crops on graduated levels built into slopes, which serves two primary purposes:1
* Maximizing Land Use: It allows for cultivation in variable, mountainous terrains that would otherwise be unsuitable for farming.3
* Resource Management: Terracing helps reduce soil erosion and minimizes water loss, ensuring that the land remains productive.3

By combining these water-control projects with the strategic use of terraced slopes, farmers in Guangxi are able to cultivate crops effectively across the region's diverse landscape.12
