The ecosystem, sustainability and agriculture

This lesson introduces students to the role of ecosystems in agricultural production, focusing on ecosystem services, management practices, and global and national consumption trends. Through discussions and case studies, students explore how population growth impacts sustainability and how agricultural practices can adapt to ensure long-term productivity. This lesson is ideal for understanding the intersection of ecology, agriculture, and resource management.

Learning Objectives:

Define ecosystems and explain their role in agricultural production.
Identify key ecosystem management practices used in agriculture.
Describe current trends in food and fiber consumption nationally and globally.
Assess the sustainability of these trends in relation to population growth.

Lesson Highlights:

• Starter Activity: Students analyze an image of a farm, identifying ecosystem services, agricultural products, and sustainable practices to improve productivity.
• Ecosystem Services Overview: Explanation of how ecosystems support agriculture through services like pollination, soil fertility, water cycling, and pest control.
• Management Practices: Discussion on soil and water management, agroforestry, crop rotation, and conservation to maintain ecosystem health.
• Consumption Trends: Analysis of global and national food and fiber consumption trends, including rising demand for meat and water-intensive crops like rice and cotton.
• Sustainability Challenges: Assessment of population growth impacts on resources and strategies like regenerative farming, plant-based diets, and recycling to address sustainability concerns.
• Complete Answers and Timed Activities: All answers are provided for guided discussions, with timers for well-paced activities.
