The analysis showed that among all the LULC changes, agricultural technology that increased cropland production had the greatest impact on SOC changes, followed by the tillage practices, changes in crop species, and the conversions of cropland to other land use.
The second scenario (ROT) is based on changes in crop rotations by introducing new crops to reduce N losses and to maintain economic profitability.
Avoiding a foreseeable systems collapse requires region-wide changes in crop systems management, underpinned by sound environmental policies.
The study found that federal mandates for biofuel production could amplify the effect of climate change on corn price volatility by hampering the market's ability to adjust to changes in crop yields.
A statistical estimator, a tool that uses only the portion of variations in crop yields across states that is predicted by changes in climate (e.g., temperature and rainfall), was used to estimate the sensitivity of emigration to crop yields.
Dietary changes leading to increased childhood obesity may be driven by changes in climate that promote or restrict agricultural crops such as fruits and vegetables; government policies; and concentration of food production, distribution, and marketing in the hands of large corporations.
The seed crop is also affected by climate change regarding change in crop phenology, reproduction, flowering, anthesis/pollen viability, and pollination/fertilization, length of seed-filling duration, seed setting, seed size, seed dormancy, seed yield, and ultimately seed quality.
We summarize change in crop production by country under both scenarios.
