2. WATER:
• Water is a vital substance essential for life on
Earth, covering approximately 71% of the planet's
surface. It exists in various forms, including liquid,
solid (ice), and gas (water vapor), and plays a
critical role in sustaining ecosystems, supporting
agriculture, facilitating transportation, and
providing a source of recreation and leisure.

3. • Chemical Composition: Water is composed of two
hydrogen atoms bonded to one oxygen atom (H2O).
This simple molecular structure gives water its unique
properties, such as high surface tension, cohesion, and
solvent capability.
• Importance for Life: Water is essential for all forms of
life, serving as a medium for biochemical reactions,
regulating body temperature, and transporting nutrients
and waste within organisms.

4. •Role in Ecosystems: Water ecosystems, including
oceans, rivers, lakes, and wetlands, support
diverse forms of life and provide habitats for
countless species. They also play a crucial role in
nutrient cycling, maintaining biodiversity, and
regulating climate patterns.
•Human Dependency: Humans rely on water for
various purposes, including drinking, sanitation,
agriculture, industry, and energy production.
Access to clean and safe drinking water is
essential for public health and well-being.

5. 1.Global Water Resources: Despite being
abundant, freshwater resources are unevenly
distributed across the planet, leading to water
scarcity in many regions. Population growth,
urbanization, pollution, and climate change
further exacerbate water challenges.
2.Water Management: Effective water
management strategies are crucial for ensuring
sustainable use and conservation of water
resources. This includes water conservation
practices, watershed management, wastewater
treatment, and the development of efficient

7. •Challenges and Solutions: Addressing
water-related challenges requires
collaborative efforts at local, national, and
international levels. This involves
implementing policies for water
conservation, investing in infrastructure for
water supply and sanitation, promoting
water-efficient technologies, and raising
awareness about the importance of water
stewardship.

9. • Water resources management is a critical endeavor that
ensures the sustainable use of water, builds climate resilience,
and strengthens integrated management. Let’s delve into the
challenges and strategies related to water management:
• Global Water Scarcity:
• Over 40% of the global population faces water scarcity, and estimates
predict a 40% shortfall between forecast demand and available supply
by 2030.
• Chronic water scarcity, hydrological uncertainty, and extreme weather
events (such as floods and droughts) pose significant threats to global
prosperity and stability.
• Acknowledgment of water scarcity’s role in aggravating fragility and
conflict is increasing.

10. • Water scarcity refers to
the situation where the
demand for freshwater
exceeds the available
supply of water in a
particular region or
during a specific period.
It is a pressing global
challenge affecting
millions of people around
the world, with significant
environmental, social,
and economic
implication.

11. • Growing Demand and Resource Constraints:
• Feeding 10 billion people by 2050 requires a 50% increase
in agricultural production (which currently
consumes 70% of water resources) and a 15% increase in
water withdrawals.
• Approximately 25% of the world’s GDP is exposed to water
scarcity challenges.
• By 2040, an estimated one in four children will live in areas
with extreme water shortages.
• Climate Change Impact:
• Climate change alters hydrological cycles, making water
more unpredictable.
• Monsoonal basins and deltas are particularly vulnerable.
• Flood damages amount to $120 billion per year, and
droughts affect rural communities heavily. animation:peek in

13. • Transboundary Challenges:
• 276 transboundary basins shared by 148 countries account for 60% of
global freshwater flow.
• 300 transboundary aquifer systems support 2.5 billion people worldwide.
• Cooperation is essential for optimal water resources management.
• Investment Priorities:
• To address these challenges, countries must invest in:
• Institutional strengthening: Enhancing governance and policy
frameworks.
• Information management: Improving data collection and sharing.
• Infrastructure development: Building both natural and man-made
systems.
• World Bank’s Role:
• The World Bank supports countries in coping with water scarcity, climate
change, and transboundary issues.
• Projects focus on sustainable water use, resilience, and integrated
management.

Management initiatives and projects. 🌊💧

It's important to note that
infants have higher water
percentages than adults,
as they have more body
water relative to their
body weight. Additionally,
factors such as hydration
levels, diet, and physical
activity can influence
water percentages in the
body.

15. • Here's a breakdown of water percentage in different
parts of the body:
• Brain and Heart: These organs contain about 73%
water.
• Lungs: Approximately 83% water.
• Muscles and Kidneys: About 79% water.
• Skin: Roughly 64% water.
• Bones: Even though bones are relatively dry, they still
contain around 31% water.
• Blood: Blood is composed of plasma, which is about
90% water.

16. •Water is the essence of life, vital for sustaining all
forms of life on Earth.
•Its significance cannot be overstated, as it plays a
critical role in maintaining bodily functions,
supporting ecosystems, and driving economic
activities.
•Despite its abundance, water scarcity remains a
pressing global challenge, threatening human
health, food security, and environmental
sustainability.

17. •Addressing water scarcity requires collective
action, innovative solutions, and sustainable
water management practices.
•By conserving water, protecting water sources,
and promoting equitable access to clean and safe
water, we can ensure a sustainable future for
generations to come.
•Let us work together to safeguard this precious
resource and ensure that water remains a source
of life, health, and prosperity for all.
