can u help with how and refernce to this part Mathematical Modelling Description of Your Model: Explain the basic mathematical model you will use to estimate the impact of deforestation on food security. Key Variables and Assumptions: Identify the key variables (e.g., rate of deforestation, crop yields, population growth) and state your assumptions (e.g., constant deforestation rate, no major technological changes). Scenario Analysis: Consider different scenarios (e.g., high deforestation rates vs. low deforestation rates) and their respective impacts on food security
