Berbagai kontroversi hadir dalam menentukan definisi yang layak mengenai istilah

[[Padang pasir]] yang diketahui saat ini terbentuk melalui proses alami dalam waktu yang sangat panjang. Selama waktu tersebut, padang pasir telah meluas dan menyusut tanpa peran campur tangan manusia. Padang pasir prasejarah berukuran lebih besar dibandingkan padang pasir terluas saat ini, yaitu Sahara, hingga dapat disebut sebagai [[lautan pasir]], yang kini stabil karena vegetasi.<ref name="Desertification">United States Geological Survey, [http://pubs.usgs.gov/gip/deserts/desertification/ "Desertification"], 1997</ref>

Mitigasi dan pencegahan umumnya fokus pada dua aspek dasar, yaitu penyediaan air dan menyuburkan tanah. Penumbuhan vegetasi rintisan sedikit membantu kedua hal tersebut, yang pada akhirnya akan diikuti oleh vegetasi lain yang lebih besar dan memberikan manfaat lebih.
Memperbaiki kondisi tanah dapat dilakukan dengan penggunaan vegetasi [[pemecah angin]]. Pemecah angin dibangun dari tegakkan pepohonan dan semak yang digunakan untuk mencegah [[erosi|pengikisan]] dan [[evapotranspirasi]] tanah yang tinggi.
Beberapa jenis tanah seperti [[tanah liat]] akan ter[[konsolidasi (tanah)|konsolidasi]] (tersatukan) (penurunan volume curah tanah) akibat minimnya keberadaan air. Pembajakan mampu mengembalikan [[porositas|keporosan]] dan volume tanah.<ref>[http://ngm.nationalgeographic.com/2008/09/soil/mann-text.html Arid sandy soils becoming consolidated; zai-system]</ref>
