Abstract
This is an experimental study that focuses on the present status of three factors that shape the current world global climate, and how it affects future agriculture, The study gives an insight on how effective are elevated CO₂, high UV-B irradiation and rising temperature on forage after 50 years’ time, keeping in mind the growing population and the increasing demand for proteins, it focuses on Chenopodium Quinoa, A C3 plant that is highly nutritious and known for its ability to tolerate high temperature, high salt concentration, and drought. Recently it got more focus and is cultivated in many places all around the globe. Several studies have been conducted on this crop to test how well will it fair in the future and if it is suited to be called future forage focusing on only two environmental stresses (Elevated CO₂, and Rising Temperature), this study will focus on exposing Quinoa to three environmental stresses (Elevated CO₂, Rising Temperature, and High UV-B light intensity) which our world is expected to face if proper policies are not placed and implemented. An Open Top Chamber approach will be used, tubes filled with soil medium to host quinoa, with normal irrigation and fertilizer input. High concentration of CO₂ of 600 ppm, high temperature of 27 C, and intense UV-B light of 9.5kj d₋₁ m₂ at 280-320 nm, will be injected into the room and exposed by the plants, biochemical and physical traits will be analyzed to evaluate changes. The evaluation mainly focused on key morphological features including fresh and dry weights, to assess the responses to various environmental stresses. The results reveal that there was a decrease in concentrations of selected micronutrients, specifically Fe and Cu, due to elevated CO₂ states. UV-B irradiation and elevated temperature had shown to negatively impact Mg and Mn decreasing its concentrations. Our findings provide empirically-oriented evidence that a strong resilience of quinoa has been demonstrated to elevated levels of CO₂, UV-B radiation, and high temperature which would strongly impact future agriculture dependence.
