Degradation, however, releases that carbon into the atmosphere. Conserving and restoring soil biodiversity is a critical component of this quest, as it ensures that vegetation for agriculture and farming is maintained all year round, including in the critical dry seasons. Making the most of existing water resources, such as by applying specialized water harvesting techniques and using treated wastewater for irrigation, are also key.
Managing livestock mobility and stocking rates also plays an important role. Traditional practices like Al Hima in Jordan — under which livestock is moved around seasonally to take account of grass life cycles — can provide useful starting points. In recent years, many migratory pastoralists have had such traditional practices limited or outlawed: governments can contribute to positive change by updating policies to grant pastoralist communities the rights and enabling factors to continue these practices.

Alluvial fans are fan-shaped piles of sediment that form where a rapidly flowing mountain stream enters a relatively flat valley. As water slows down, it deposits sediment alluvium. As the stream migrates back and forth in the open valley, the sediment gradually builds a fan. Bajadas are are aprons of rocky debris that form when alluvial fans coalesce to form a ramp that spreads out toward the valley floor.
A bajada or piedmont slope partially buryies the range front in its own sediment. Stream terraces are long bench-like surface bordering a stream or wash. A terrace is a level or near-level area of land above a water course and separated from it by a steeper slope.
A stream terrace is made by the stream at some time in the past when the river flowed at a higher level. A terrace may be made of stream deposits such as gravel or sand, or it could be an erosional cut by the stream on bedrock.
Playas are shallow, short-lived lakes that form where water drains into basins with no outlet to the sea and quickly evaporates. Playas are common features in arid desert regions and are among the flattest landforms in the world.
Rock particles that wash down from mountain sides collect in adjacent basins, in some places burying the bedrock under thousands of feet of rock debris. Show 10 40 per page.

Erosional processes in arid and semi-arid regions include: mass wasting surface creep, landslides, mud and debris flows, and rock topples and falls , water-driven or fluvial processes , and wind-driven or aeolian processes dust, loess, sand dunes. Erosional Features and Landforms Mesas and Buttes Mesas are broad flat topped mountains with at least one steep side.
