Irrigation in Brazil - Possible Climate Change Impacts

Possible Climate Change Impacts

Global climate change will affect the climate of Northeast Brazil. According to an assessment by Krol and Van Oel for the State of Ceara, the direction of precipitation changes cannot be determined with certainty. Both very significant precipitation losses and moderate precipitation increases should be considered plausible. The impacts of precipitation losses would cause large-scale reductions in the availability of stored surface water, leading to an increasing imbalance between water demand and water supply after 2025. Agricultural production would show negative tendencies after 2025 due to insufficiency of water supply to meet irrigation water demands.

Famous quotes containing the words climate, change and/or impacts:

    “Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
    —Anton Pavlovich Chekhov (1860–1904)

    “Wisdom is not just knowing fundamental truths, if these are unconnected with the guidance of life or with a perspective on its meaning. If the deep truths physicists describe about the origin and functioning of the universe have little practical import and do not change our picture of the meaning of the universe and our place within it, then knowing them would not count as wisdom.”
    —Robert Nozick (b. 1938)

    “We are no longer in a state of growth; we are in a state of excess. We are living in a society of excrescence.... The boil is growing out of control, recklessly at cross purposes with itself, its impacts multiplying as the causes disintegrate.”
    —Jean Baudrillard (b. 1929)
