The National Center for Vegetation Development and Combating Desertification (NCVC) launched a major project to rehabilitate 620,000 hectares of degraded land in Saudi Arabia, reported the Saudi Press Agency on Tuesday.

The project will use rainwater harvesting techniques to improve vegetation cover in nine regions across the Kingdom.

It will involve studying the feasibility of implementing rehabilitation projects in three main climatic regions, continental, coastal, and mountainous, and identifying the target areas, the appropriate rainwater harvesting techniques, and the activities to be carried out in each region.

NCVC will also collect climate and hydrological data, study topographic and survey maps, and analyze satellite imagery. Field visits will be conducted to collect soil and water samples, carry out field measurements and laboratory analyzes, and identify the drainage network of the main basins in the study areas.

The project is expected to yield several outputs, such as uncovering the root causes and severity of land degradation, cataloging existing plant species and their numbers, recommending suitable plant types for restoration and their optimal propagation methods, calculating the seed or seedling needs for designated areas, identifying ideal planting times, establishing the desired ratio of plants not good for grazing to those good for grazing, and determining rainfall patterns, water requirements, and areas targeted for cultivation.

The project will also determine the most effective rainwater harvesting system for each site.

The project is part of NCVC's efforts to combat desertification and improve the environment in Saudi Arabia. It is aligned with the goals of Saudi Vision 2030, which aims to achieve sustainable development and protect the environment.

Rainwater harvesting is a technique used to collect and store rainwater for later use. The project will use a variety of rainwater harvesting techniques, including making use of dams, reservoirs, cisterns, and wells.

Scientists have identified a super resilient desert moss species in China's western region of Xinjiang that could help sustain possible colonies on Mars, a study by the Chinese Academy of Sciences showed.
When subjected to conditions that simulate the environment on Mars, the moss - Syntrichia Caninervis - was found to be able to withstand extreme dryness, ultra-low temperatures and radiation, the academy said in a research paper published in The Innovation journal last week.
The moss could serve as the "basis for the establishment and maintenance of the ecosystem by contributing to oxygen production, carbon sequestration, and soil fertility", the researched said in the study, published on July 1.
"(It) can help drive the atmospheric, geological, and ecological processes required for other higher plants and animals while facilitating the creation of new habitable environments conducive to long-term human settlement," the paper added.
In the research, scientists found that even after losing more than 98% of its cellular water content, the moss was able to recover photosynthetic and physiological activities within seconds after it was hydrated.
When intact, the plant can also tolerate ultra-low temperatures and regenerate after being stored in a freezer at minus 80 degree Celsius (minus 112 Fahrenheit) for five years or in liquid nitrogen for a month, Reuters reported.
The moss is found in Xinjiang, Tibet, a Californian desert, the Middle East and polar regions.
The race to place a larger footprint in space has spurred China and the United States to launch exploration plans in recent years.
Chinese missions include launching near-Earth asteroid probe Tianwen-2 next year, and Tianwen-3 around 2030 to bring samples back from Mars. China last month retrieved samples from the far side of the moon.
In the United States, NASA has formulated a 20-year plan for Mars, seeking answers to whether the red planet is habitable for humans.
