Introduction

Class performance is similar to previous students taking the exam. The average score recorded was 87.5 out of 90, indicating that most students scored high A's. Students close to the 87.5 mark can still raise their grades through participation and online assignments.

Exam Performance

Students need to focus on easy credits such as attendance and participation to enhance their grades. It is crucial to communicate clearly on grades and the consequences of not performing well on exams. If a student performs poorly on the first exam but takes the second exam on time, they can avoid a comprehensive exam.

Exam Structure

The exam covered key topics that included:

• Environmental Degradation: Factors contributing to environmental degradation and its implications.

• Importance of Accuracy in grading and the necessity to address any miscalculations immediately.

Engaging in Class

There is encouragement for students to actively participate in discussions to improve performance. Shy students should understand that engagement can lead to a better understanding of content and improve exam performance. Questions on clarifications or topics covered in class are welcomed by the instructor.

New Topics for Exam Two

Focus will shift to sustainable cities with emphasis on:

• Environment

• Economy

• EquityAdditionally, a discussion on water as a vital resource for survival will be initiated.

Water Use and Management

The discussion will cover the planning of water resource management and factors threatening the fresh water supply. Key considerations include:

• Urban Sprawl: Increases demand for water; single-family homes require significant irrigation.

• Runoff and Pollution: Impacts from urban planning can lead to contamination of water resources.

• Groundwater Depletion: Issues surrounding groundwater depletion in the U.S. and challenges faced in developing countries will also be addressed.

Federal Regulations on Water

An overview of the Safe Drinking Water Act and the Clean Water Act in the U.S., which ensure the quality of drinking and recreational water, will be provided.

Global Water Issues

Issues related to freshwater scarcity and threats due to climate change will be discussed. Insights from NASA’s GRACE mission data on freshwater storage trends globally will be shared. Specific regional observations include:

• Western U.S.: Experienced drought impacting water supplies.

• Northern Saudi Arabia: Faced reduced water supplies due to agricultural expansion.

• Northwestern China: Showed unexplained freshwater loss.

UAE Water Management Strategies

The UAE water crisis is projected for 2050 due to rapid urbanization and population growth. Current water sources include groundwater, desalinated water, and treated wastewater. Notable developments include:

• Desalination Technology: Significant responses to water scarcity through technological advancement.

• Importance of Renewable Energy: For sustainable desalination processes.

• Conservation Strategies: Innovations initiated by UAE, such as water recycling initiatives targeting 100% reuse by 2030 and cloud seeding for increased rainfall. Public awareness campaigns are in place to encourage responsible water usage.

Challenges of Water Supply in Developing Countries

Discussion points include informal settlements that lack access to clean water and the necessity for international support to improve water infrastructure. Pollution threats from improper waste disposal into natural water bodies will also be highlighted.

Class Reflection

There will be discussions on the implications of urban land use decisions on water pollution. Examples of pollution from old parking lots, considered brownfields, will be discussed, emphasizing the importance of investigation for potential contamination before repurposing land.
