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 ...
These techniques may be used in the identification of flood dynamics, [22] [23] storm characterization, [24] [25] and groundwater flow in karst systems. [26] Regression analysis is used in hydrology to determine whether a relationship may exist between independent and dependent variables.
There are some regions in which flooding is expected to become rarer. This depends on several factors. These include changes in rain and snowmelt, but also soil moisture. [59]: 1156 Climate change leaves soils drier in some areas, so they may absorb rainfall more quickly. This leads to less flooding. Dry soils can also become harder.
Recessional agriculture, also known as flood retreat agriculture, is a form of agricultural cultivation that takes place on a floodplain. Farmers practice recessional agriculture by successively planting in the flooded areas after the waters recede. [1] Seeds are scattered on the fertile silt deposited by the receding flood.
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 ]
long-term population dynamics; global environmental change; the prevalence and persistence of hunger; sustainability science [7] Following the devastation of New Orleans after Hurricane Katrina, Kates returned to his earlier work on hazards and published a research perspective on the reconstruction of New Orleans (Kates et al., 2006).
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 ...
Spate irrigation (from the English word spate, meaning: a. a flood or inundation. b. a river flooding its banks) uses seasonal floods of rivers, streams, ponds and lakes to fill water storage basins. It is an ancient method of irrigation in arid and semi-arid climates in the Middle East, North Africa, West Asia, East Africa and parts of Latin ...
