co2 global effects

RISING CO2 CLIMATE CHANGE PROJECTED TO REDUCE AVAILABILITY OF NUTRIENTS WORLDWIDE.

 ONE OF THE BIGGEST CHALLENGUS TO REDUSING HUNGER AND UNDERNUTRITION AROUND THE WORLD IS TO PRODUCE  FOOD THAT PROVIDE NOT ONLY  ENOUGH CALORIES  BUT ALSO MAKE ENOUGH NECESSARY NEUTRIENTS WIDELY AVAILABLE.

OVER THE NEXT 30 YEAR CLIMATE CHANGE AND INCREASING CO2 COULD SIGNIFICANTLY  REDUCE THE AVAILABILITY OF CRITICAL NUTRIENTS  SUCH A PROTEIN IRON AND ZINC COMPARED TO A FUTURE  WITHOUT CLIMATE CHANGE.

THE TOTAL IMPACTS OF CLIMATE CHANGE SOCKS AND ELEVATED LEVELS  OF CO2 IN THE ATMOSPHERE ARE ESTIMATED TO REDUCE GROWTH IN GLOBAL PER CAPITA NUTRIENT AVAILABILITY  OF PROTEIN IRON ZINC BY 19.5%,14.4%AND 14.6% RESPECTIVELY.

THE IMPECT GLOBALE  AGRIL SECTOR MODEL ALONG WITH  DATA FROM GENUS MODEL AND TWO DATA SETS ON EFFECTS OF CO2 ON NUTRIENT CONTENT IN CROPS RESEARCHERS PROJECTED PER CAPITA AVAILABILITY OF PROTEIN IRON ZINC OUT OF 2050.

HIGHER LEVELS OF CO2 CAN BOOST PHOTOSYNTHESIS AND GROWTH  IN SOME PLANTS PREVIOUS RESEARCH HAS ALSO FOUND THE REDUCE THE CONCENTRATION

OF KEY MICRO NUTRIENTS IN CROPS THE NEW STUDY FINDS THAT WHEAT RICE MAIZE BARLEY  POTATOES SOYBEANS AND VEGETABLES ARE ALL PROJECTED TO SUFFER NUTRIENT LOSSES  AT ABOUT 3% ON AVERAGE BY 2050 DUE TO ELEVATED  CO2 CONCENTRATION.

NUTRIENTS REDUCTIONS ARE PROJECTED TO BE PARTICULARLY  SEVERE IN SOUTH ASIA, THE MIDDLE EAST, AFRICA  AND FORMER USSR REGIONS LARGELY   COMPRISED LOW AND MIDDLE-INCOME COUNTRIES WHERE LEVELS OF UNDER NUTRITION  ARE GENERALLY HIGHER AND DIETS ARE MORE VULNERABLE TO DIRECT IMPACTS OF CHANGES IN TEMPERATURE AND PRECIPITATION TRIGGERED BY CLIMATE CHANGE
