Local weather change is inflicting “hazard flips”, the place areas that was once liable to drought expertise flooding, and vice versa.

In northern Italy, the variety of intense dry spells has greater than doubled since 2000 – however these have been punctuated by excessive flooding, together with deadly floods in May and June this year.
Earlier than that, a winter of little snowfall left a walkway in Lake Garda exposed and Venice battling dry canals.

The analysis examined flooding and drought hazards over the past 41 years throughout six nations: Pakistan, Ethiopia, Uganda, Burkina Faso, Ghana and Mozambique. Italy was included as a European comparability.
On the whole, the nations that used to expertise frequent droughts that at the moment are extra liable to frequent flooding, whereas others traditionally liable to flooding now endure extra frequent droughts.

“From drought-stricken farmlands to flood-ravaged settlements, communities in Pakistan, Burkina Faso, Ghana and Ethiopia are all experiencing alarming local weather whiplash results; Uganda is experiencing ever extra catastrophic flooding and Mozambique a chaotic mixture of each extremes.
“Whereas we’ll all pay a value for world water stress, it is these dwelling on the frontline of the local weather disaster who’re paying for it now – their lives hanging within the steadiness.”

WaterAid spoke to retired main college trainer Okecho Opondo, 70, who stated the change in climate patterns was creating “complete confusion”.
“The months that was once wet at the moment are dry. When the rains come, they are often brief but heavy, resulting in floods.
“On different events the wet durations are too lengthy, resulting in destruction of infrastructure and crop failure. After which the dry durations could be very lengthy, additional resulting in crop failure and starvation.”
