In 2021, a paper which used an ensemble of 21 climate models estimated that under the most intense climate change scenario used at the time, RCP8.5, global yields of these four crops would decline by between 3–12% around 2050 and by 11–25% by the year 2100. The losses were concentrated in what are currently the major agricultural producers ...
Flood-recession cropping may be seriously affected by the upstream interception of river water for irrigation purposes. In Baluchistan , Pakistan , the development of new small-scale irrigation projects depleted the water resources of nomadic tribes traveling annually between Baluchistan and Gujarat or Rajasthan , India [ 15 ]
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...
The 1862 flood has been used as a key data point in creating the "ARkStorm Scenario," originally projected as California's once-in-a-thousand-years catastrophic flood event, but now some ...
Research into desertification is complex, and there is no single metric which can define all aspects. However, more intense climate change is still expected to increase the current extent of drylands on the Earth's continents: from 38% in late 20th century to 50% or 56% by the end of the century, under the "moderate" and high-warming ...
Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience .
Flooding is a natural process, which maintains ecosystem composition and processes, but it can also be altered by land use changes such as river engineering. Floods can be both beneficial to societies or cause damage. Agriculture along the Nile floodplain took advantage of the seasonal flooding that deposited nutrients beneficial for crops ...
Over 82% of Thai agricultural land relied on rainfall. Thai farmers were not able to grow crops for lack of water. Although scientific evidence seems to suggest that cloud seeding does not ameliorate droughts, [ 3 ] [ 4 ] the Royal Rainmaking Project debuted on 20 July 1969 at the king's behest, when the first rainmaking attempt was made at ...
