6 FAQs about [Chad water storage]
What is the variation total water storage of Lake Chad?
The variation total water storage (TWS) of Lake Chad is the sum of SWS, groundwater and root zone soil moisture (called subsurface water storage; SSWS). The spatial temporal variation of TWS and root zone soil moisture are estimated using GRACE and GLEAM dataset, respectively, and the variation of SWS is estimated using Eq. (2) 64, 67.
Does Lake Chad still have water?
With the supply of groundwater and tropical water sources, the water level and area of Lake Chad, as observed by altimetry and satellite images, have gradually recovered over the past two decades (Pham-Duc et al., 2020).
Why does Lake Chad have more groundwater?
Moreover, since the 2000s, groundwater, which contributes to ~70% of Lake Chad’s annual water storage change, is increasing due to water supply provided by its two main tributaries.
Can Lake Chad be a solution to the water crisis?
Given time and cooperation, the people who rely on Lake Chad for water, fishing and daily life may be able to achieve a solution to the water crisis they face. With the natural disasters, sustainable tactics will be vital for restoring Lake Chad. Unfortunately, over the last few decades, Lake Chad’s water supply has been diminishing.
Why does Chad have a low water supply?
Increased water extraction for irrigation is estimated to be responsible for at least 50 per cent of this decrease, although repeated severe drought is also to blame . Chad has the third-lowest level of access to safe water and the lowest level of access to adequate sanitation in all of Africa.
Why is Lake Chad so dangerous?
Since they can no longer find food or clean water, competition for these needs has created conflict in the region and the lack of water has also led to unsanitary conditions. The conditions of Lake Chad are not only hostile because of nature. Lack of water has an extreme effect on the human body and children can be among the most vulnerable.
