This global overview by Testbiotech documents several case studies showing how genetically engineered plants such as maize, rice, cotton, oilseed rape, bentgrass and poplar trees are spreading uncontrollably.
This article evaluates the implications of uncertainty in the life cycle (LC) energy efficiency and greenhouse gas (GHG) emissions of rapeseed oil (RO) as an energy carrier displacing fossil diesel (FD). Uncertainties addressed include parameter uncertainty as well as scenario uncertainty concerning how RO coproduct credits are accounted for (uncertainty due to modeling choices).
Agriculture in India is subject to variety of risks arising from rainfall aberrations, temperature fluctuations, hailstorms, cyclones, floods and climate change. These risks are exacerbated by price fluctuation, weak rural infrastructure, imperfect markets and lack of financial services including limited span and design of risk mitigation instruments such as credit and insurance.
Emphasis on resource conservation and their efficient utilization, availability of high yielding crop varieties of varying duration and growth rhythms, integrated approach for plant protection measures, availability and use of fertilizer nutrients, non availability of additional urea for agriculture, decline in input use efficiency over the years and decrease in per capita land holding, has changed the concepts of intercropping.
