Long-Term Global Trends in Crop Yield and Production Reveal No Current Pollination Shortage but Increasing Pollinator Dependency
There is evidence that pollinators are declining as a result of local and global environmental degradation [1-4]. Because a sizable proportion of the human diet depends directly or indirectly on animal pollination [5], the issue of how decreases in pollinator stocks could affect global crop production is of paramount importance [6-8]. Using the extensive FAO data set [9], we compared 45 year se...
متن کاملRandom Forests for Global and Regional Crop Yield Predictions
Accurate predictions of crop yield are critical for developing effective agricultural and food policies at the regional and global scales. We evaluated a machine-learning method, Random Forests (RF), for its ability to predict crop yield responses to climate and biophysical variables at global and regional scales in wheat, maize, and potato in comparison with multiple linear regressions (MLR) s...
متن کاملClimate variation explains a third of global crop yield variability
Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive. We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. While s...
متن کاملAutomated Pollinator Monitoring for Crop Farming
Pollinating bee species face an increased risk of extinction worldwide. The annual value of this pollination service in the U.S. is calculated at US $ 15 billion and the estimate worldwide is US $ 65 – 70 billion. But, endeavors on pollinator monitoring and management must build on reliable surveillance and monitoring of pollinator species. This contribution presents the ABIS toolset for specie...
