Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle ) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
Grassland in Europe. Grassland degradation, also called vegetation or steppe degradation, is a biotic disturbance in which grass struggles to grow or can no longer exist on a piece of land due to causes such as overgrazing, burrowing of small mammals, and climate change. [1]
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. [2]
"The grass roots can suffocate due to a lack of oxygen in overly wet soil, weakening the lawn," says McCausland. "Standing water can compact the soil, reducing drainage and harming root ...

Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
Papyrus plant (Cyperus papyrus) at Kew Gardens, LondonThis tall, robust aquatic plant can grow 4 to 5 metres (13 to 16 ft) high, [5] but on the margins of high altitude lakes such as Lake Naivasha in Kenya and Lake Tana in Ethiopia, at altitudes around 1,800 m (6,000 ft) the papyrus culms can measure up to 9 m (29 + 1 ⁄ 2 ft) in length, with an additional 46 centimetres (18 in) for the ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
