Leveraging Small-scale Hydro Power for Disaster Resilience in Developing Economies

However, small-scale hydro power systems have emerged as a promising solution to enhance disaster resilience in these vulnerable areas.

Small-scale hydro power involves harnessing the power of flowing water to generate electricity on a smaller scale. Unlike large-scale hydro power plants that require large dams and reservoirs, small-scale systems can operate with much smaller water flow rates, making them suitable for communities located near rivers, streams, or even small waterfalls.

The Advantages of Small-scale Hydro Power:

  • Clean and Renewable Energy: Small-scale hydro power systems are fueled by a naturally replenishing resource—water. Unlike fossil fuel-based electricity generation, hydro power produces no greenhouse gas emissions or other harmful pollutants, making it an environmentally friendly option.
  • Cost-effective: Once installed, small-scale hydro power systems require minimal operational costs. The initial setup cost may vary depending on the size and complexity of the system, but the long-term savings on electricity bills can be substantial, benefiting both individuals and communities.
  • Reliable and Stable: Flowing water is a consistent and reliable source of energy. Unlike solar and wind power, which are subject to weather conditions, small-scale hydro power systems can operate consistently, providing a stable source of electricity to communities at all times.
  • Enhances Resilience: In disaster-prone areas, access to electricity is crucial for emergency response efforts, communication, and critical infrastructure such as hospitals and water treatment facilities. Small-scale hydro power can provide a reliable source of electricity, even during times of disaster or grid failures.
  • Community Empowerment: Implementing small-scale hydro power encourages local involvement and ownership. Communities can benefit economically by selling excess electricity to the grid, stimulating economic growth and creating job opportunities.

According to the International Small Hydro Atlas, small-scale hydro power accounts for approximately 78 GW of installed capacity worldwide, with the potential to generate over 400 TWh of electricity annually. While developed countries have already tapped into this potential, developing economies have a vast untapped resource waiting to be leveraged.

The Role of Small-scale Hydro Power in Disaster Resilience:

Disasters often disrupt the functioning of traditional centralized power grids, leaving communities without electricity for extended periods. This lack of power can further hamper rescue operations, delay recovery efforts, and put vulnerable populations at increased risk.

However, small-scale hydro power systems can serve as decentralized energy sources that operate independently of the grid. By integrating these systems into disaster-prone areas, communities can ensure a continuous supply of electricity during and after disasters. Key benefits include:

  • Emergency Preparedness: Small-scale hydro power systems can power emergency communication systems, enabling rapid dissemination of information and instructions during disasters. This enhances preparedness and improves response times.
  • Strengthening Infrastructure: Small-scale hydro power can contribute to the electrification of critical infrastructure like hospitals, schools, and water treatment facilities. By ensuring their functionality during disasters, it enables communities to better cope with emergencies and enhances the overall resilience of the area.
  • Increased Self-sufficiency: Communities with small-scale hydro power systems can become less reliant on centralized power grids, reducing vulnerability to grid failures caused by natural disasters. This increased self-sufficiency fosters resilience and enables faster recovery.

While the benefits of small-scale hydro power for disaster resilience in developing economies are evident, there are challenges that need to be addressed. These challenges include high upfront costs, lack of technical expertise, and the need for favorable policies and regulations.


Small-scale hydro power systems present a compelling solution for enhancing disaster resilience in developing economies. By leveraging the power of flowing water, these systems offer clean, cost-effective, and reliable energy sources that are vital during emergencies. Furthermore, they empower local communities and contribute to economic growth.

As the world faces an increasing number of natural disasters, it is crucial for policymakers and stakeholders to recognize the potential of small-scale hydro power and work towards its widespread implementation. By prioritizing small-scale hydro power, developing economies can build stronger, more resilient communities that are better equipped to withstand the challenges posed by disasters.

Key Takeaways:

  • Small-scale hydro power systems utilize flowing water to generate electricity on a smaller scale.
  • Advantages include clean and renewable energy, cost-effectiveness, reliability, and community empowerment.
  • In disaster-prone areas, small-scale hydro power ensures access to electricity during and after disasters.
  • Benefits include emergency preparedness, strengthening critical infrastructure, and increased self-sufficiency.
  • Challenges include upfront costs, expertise, and regulatory support.
