Unit A: Case Study, The Sahel

How to Use the Case Study

The power point has four sections that help provide a context for the importance of studying the Sahel region as a case study for climate change. It also provides a window into the real-life effects that climate change has bestowed upon 100 million people in the region. Leaving them vulnerable to famine, food insecurity, disease, displacement, and force migration.

The case study also provides opportunities for students to feel empowered by learning how sustainable solutions to some of the pressing problems facing the Sahel can be mitigated. Students engage a design challenge that propels them into studying the problem of lack of clean water and sanitation facing millions not only in the Sahel but around the world.

Introduction

The case study of the Sahel is to convey how changes in climate are adversely impacting people in this region. It also highlights efforts to help populations in these regions adapt to these changes by empowering them affordable and sustainable resources to counteract some of the effects of climate variability.

This case study also introduces students to ideas and practices of sustainable design solutions to address global issues such as the lack of clean water.

Section I. The Sahel

Instructional Goal

Students become familiar with the geographical region of the Sahel.

Reading

Instructional Goal

Help student gain an understanding of the challenges facing the Sahel Region due to the adverse impact of climate variability.

Learning Objectives

  • Describe and identify how the prolonged drought in the Sahel has affected its’ inhabitants.
  • Identify what are the geographic areas of the Sahel that have been affected.

Activity

Section III. Is The Climate Changing In The Sahel?

Instructional Goal

Learn how to identify the signs of climate variability in the Sahel and how the prolonged drought has affected the regions vegetation.

Learning Objectives

  • List what time during the year is there increased and reduced precipitation
  • Learn how data collected from satellites can document changes in vegetation cover
  • Identify the main cause that has affected vegetation growth in the region.

Activity

Section IV. Mitigation and Sustainable Practices

Instructional Goal

Learn and describe what are some of the sustainable agricultural practices being implemented by farmers in the Sahel to help mitigate the effects of drought on vegetation and crops.

Learning Objectives

  • List specific methods being used by farmers to reduce water runoff.
  • List specific methods being used to improve water management.
  • Identify how farmers and the people of the Sahel are contribution to reforestation.
  • Identify what methods farmers are using to increase crops and yield.

Section V. Access to Clean Water

Instructional Goal

Engage students in a sustainable design project that will allow them to view the challenge of access to clean water from a problem-solving perspective.

Learning Objectives

  • Conduct research and use information to engage in socially responsible design.
  • Think critically, solve problems and use information to develop, design and build a product.
  • Communicate idea and collaborate to inform the design process and execute plans.
  • Design and build a water filtration prototype.
  • Demonstrate creativity and think critically to find viable design solutions, implement and execute them.
