💔Africa has a MAJOR Cabro / impervious paving problem and it is causing all sorts of #ClimateAdaptation, #WaterPollution, #WaterScarcity, #UrbanFlooding and #drainage problems.

The 'Nouvea Riche' and contractors in Kenya, Nigeria and Ghana are especially notorious for this! ImageImageImageImage
Someone, somewhere lied to us that never seeing soil is the ultimate sophistication.

Now everyone has covered everything in hideous cabro and plastic turf 😭

Impervious surfaces like Cabro do not allow water to seep into the ground.

And that causes SEVERAL issues:
1. Water scarcity.
Cabro makes water flow fast into drains.
When water does not seep into the ground, it means that natural groundwater is not recharged.

The water we use, our rivers, boreholes, wells, depend on rainfall slowly seeping into the soil for recharge.

Forests are important. Here’s why🧵 1/n

Forests
- make shade & cool the surface
- capture CO2
- purify the air
- make clouds & rain
- prevent drought
- prevent flooding
- prevent erosion

2/n. Forests act as stabilisers for earth’s climate. They’re essential for our survival. And they’re under extreme threat.

3/n. Our ecosystem, the one we rely on survival for, relies heavily on forests. Our farmers rely on the steady rains forests bring.

Ironically agricultural expansion drives almost 90 percent of global deforestation.

-Request @cleanganganmcg @CPCB_OFFICIAL to also look into changes in riparian biodiversity in addition to conventional chemical analyses. Apart from good #rainfall, halt in sand mining hs helped #Yamuna with lean season flows. @RajivRanjanMis5
