Short rain hampers Plant productivity and Environment
According to NASA satellite report, global plant productivity is going down due to regional drought. Few years back the scenario was totally different, there was a huge rise in plant production due to the availability of favorable temperature and lengthy growing season.
Plant productivity is nothing but a rate at which photosynthesis process occur in green plants. Plant performs photosynthesis to convert solar energy, Carbon dioxide, and water to sugar, oxygen, and essential plant tissue. During 80’s and 90’s, the plant productivity was increased to 6% but it seems to decline by 1% over the last decade. This drop in plant productivity could put a question mark in food security, biofuels, and the global carbon cycle.
Two well known researchers, Maosheng Zhao and Steven Running, University of Montana in Missoula, have observed global shift by analyzing the data received from NASA satellite. The observance was done from an analysis of plant productivity data from the Moderate Resolution Imaging Spectroradiometer on NASA’s Terra satellite, combined with other growing season climate data, including temperature, solar radiation and water.
Researcher were bit surprised when they receive the final report after the analysis of raw data from NASA’s Terra satellite. When compared with previous interpretation in respect to global warming, the latest report was pointing towards reduced instead of high plant growth around the world.
