[World Meteorological Association] Deforestation in Brazil's Amazon rain forest declined by 27 percent in the year ending July 31 — the lowest level in nearly a quarter century.
Emissions of sulfur dioxide, a top priority in China in recent years because of its role in acid rain, have declined across China but particularly in Guangzhou, a city of 15 million people, including migrants.
Over the last three decades, as thousands of acres of trees, bushes and other vegetation in New York have been paved over, the land's ability to absorb rain has declined significantly.
Surface temperatures are rising, rainfall and stream flow has generally declined, rain intensity has increased, sea level and sea surface temperatures have increased, and the ocean is acidifying.
Then the rain of dust declined over a period of about 1.5 million years to near-normal levels.
The results revealed that Ethiopian summer rainfall (long rain season) has been declined by 70.51 mm in the past four decades (1971 2010); while the best performed models having similar trends to the historical observed rainfall data analysis predicted that the future summer mean rainfall amount will decline by about 60.07 mm (model cccma) and 89.45 mm (model bccr).
Due to decreased surface water flows from limited rain and snowpack, hydropower declined during the drought and most substantially in 2015.
Our previous work has shown that in abandoned fields the abundance and species diversity of regenerating rain forest trees decline as disturbance level increases.
Overgrazing observed and livestock preferred grass species such as C. ciliaris and C. plumulosus declined El nino rains eroded soil conservation structures on the farms and soil erosion contributed to a decline in crop production Boru Guyo Boru 1986–1993 A major drought called the drought of yellow maize (Olla dima suggah) occurred.
Overgrazing of plants, combined with the adverse effects of bare soil and moribund grasses, exacerbates an already declining rain-use efficiency through both increased runoff and soil surface evaporation of water (Snyman 1998; Savory 1999; Huxman et al. 2004).
