The Kalu Ganga Basin in Sri Lanka is generally flooded once a year. A network of low-lying lands acts as natural retention and storage that captures floodwater, minimizing damage. An increase in the flood frequency has been observed in recent years. It is commonly perceived that this increase is caused by a rise in the frequency and severity of ‘very wet’ precipitation events.

Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or lost entirely.

Understanding the combined and separate effects of climate and land use change on the water cycle is necessary to mitigate negative impacts. However, existing methodologies typically divide data into discrete (before and after) periods, implicitly representing climate and land use as step changes when in reality these changes are often gradual.

O Perfil Rápido do Sector Urbano para Sustentabilidade (RUSPS) é um processo de avaliação rápida e proactiva de necessidades urbanas e lacunas de capacitação institucional a níveis nacional e das cidades.

Pacific Island Countries (PICs) are often cited as being the most vulnerable to the future impacts of a changing climate. Furthermore, being located in the ‘Pacific Rim of Fire’, PICs have long been exposed to the impacts of a range of natural and climate-related extreme events—such as earthquakes and cyclones—and are considered to be amongst the most vulnerable countries to natural disasters.
