The most negative impacts of drought for humans include crop failure, food crisis, famine, malnutrition, and poverty, which lead to loss of life and mass migration of people. [27] There are negative effects on the health of people who are directly exposed to this phenomenon (excessive heat waves).
People displaced as a result of desertification can lead to increased competition for scarce resources and conflicts, worsening economic issues. [39] Desertification's detrimental effects on ecosystems and biodiversity can have far-reaching consequences for industries like tourism and ecotourism, which rely on healthy ecosystems to attract ...

But if the nations involved in the Paris talks stay on their current emissions track and don’t reduce greenhouse gas emissions, temperatures could go up by almost 6 degrees Celsius this century, according to the Committee on Climate Change, an independent body that advises ...
Effects of climate change could have different impacts on groundwater storage: The expected more intense (but fewer) major rainfall events could lead to increased groundwater recharge in many environments. [64]: 104 But more intense drought periods could result in soil drying-out and compaction which would reduce infiltration to groundwater. [67]
Valerie Amos, UN Humanitarian Chief during 2012, released a statement during the year stating that over 15 million people were malnourished in West Africa and the Sahel region.
