How can water resource agencies make smart investments to ensure long-term water reliability when the future is fraught with deep climate and economic uncertainty? Water resource agencies around the world are grappling with this question at a time of unprecedented water stress, growing demands, uncertain climate change, and limited budgets. We helped SEDAPAL, the water utility serving Lima, Peru, answer this question by drawing on state of the art methods for decision making under deep uncertainty.

Lima is home to approximately 9.8 million people. It is the fifth largest metropolitan area in Latin America. With average precipitation of just 6 mm per year, it is also the second largest desert city in the world. A rapidly growing population with approximately one million underserved urban poor, current water shortages, competition for water between sectors, wide rainfall variation due to El Niño effects, and long-term climate change impacts may leave the region under perpetual water stress.

Recognizing the urgency of Lima’s water situation, SEDAPAL has developed an aggressive multi-billion dollar Master Plan to implement 14 large and diverse infrastructural investments projects between now and 2040 at a total cost of US$2.7 billion. Together, the investments are designed to meet the 30 percent increase in water demand that SEDAPAL projects for the coming decades.

How Countries Can Improve Access to Water for Women

Because of water’s multidimensional role in economic development and poverty reduction, addressing the constraints that women and girls face in accessing and managing water is essential for achieving impact. 

Challenges of gender inequality in water include:
  • Women are disproportionately underrepresented in water sector decision making at many levels.
  • Women and girls are often charged with domestic water collection, disadvantaging other spheres of life, such as education.
  • Men benefit disproportionally from economic opportunities generated by the capital-intensive nature of water development and management.
  • Women and girls have specific sanitation needs, both for managing menstruation and for protection against gender-based violence. 

What Do Toilets and Cell Phones Have in Common?

They both hold the potential to help meet the needs of the poor and end poverty. New ideas and innovative solutions are critical to address the 2.5 billion people who lack access to proper sanitation. Lack of access to clean water and sanitation kills more than 4,000 children a day and a lack of sanitation results in billions of dollars in economic losses to developing countries. Now that more people have access to a mobile phone than to a toilet or latrine, it’s time to leverage technology to help reach development goals.
