Colonization in urban areas of Pakistan has increased significantly in recent decades, converting large areas of agricultural land to residential and commercial use. Key factors driving this include rural-urban migration, low agricultural productivity, and lack of developed land for housing and industry. Both planned developments like Bahria Town and unplanned informal settlements have expanded. This has adversely impacted food security and the environment by reducing fertile land and vegetation. Weak government policies and the power of land mafias have further enabled unchecked urban encroachment on rural areas.
