Monitoring winter wheat growth and development through different climate change scenarios

Global climate change, including increasing atmospheric CO2 concentrations, temperature rise, and variable precipitation patterns, is expected to have significant impacts on the development and production of many agricultural crops. Winter wheat (Triticum aestivum, L.), one of the world's most important crops that plays a major role in the global economy and food security, is one of the crops most affected by climate change. Climate warming has significant impacts on winter wheat development, which in turn leads to yield losses, mainly due to shortened phenological events associated with reduced assimilate production, and biochemical irregularities. The intensity and duration of warming trends and heat waves are expected to be even more extreme in the future than today, resulting in even greater production losses. In this context, appropriate adaptation measures may be needed. Therefore, it is important to better understand how wheat growth and development are changing and how they might be affected by additional stresses due to climate change in the future. The main focus of this scientific work is to monitor winter wheat growth and development based on different climate change scenarios using an Iot- based encapsulated design system. The proposed system provides equipment that can be used to rapidly conduct a series of different crop experiments simultaneously in a climate- encapsulated chamber system with an extensive network of climatic sensors and using multispectral cameras. These sensors are connected to the central database in a computer cloud, which serves as a repository for climate data that can further be correlated with plant identifiers collected by the multispectral cameras. Simulations of two different climate change scenarios as proposed by the IPCC group (global temperature increase from 0.3 to 4.8 °C by the end of the 21st century) are artificially generated and implemented in a prototype climate chamber where winter wheat plants are grown. Changes in winter wheat development at different phenophases will be monitored using multispectral cameras. Plant development will be presented in terms of vegetation indices (NDVI, PRI, SR, GNDVI, SAVI, etc.), which will provide indirect measurements of biophysical parameters such as biomass, LAI, plant height, and biochemical parameters such as plant pigment and water content.
