We're learning how invasive algae are being used to detect cesspool contamination across Hawai?i. Cesspools are leaching excess nutrients into the environment, contaminating our water systems, and negatively affecting the growth of algae and coral reefs. Hawaii has less than 30 years to replace over 80 thousand cesspools. Scientists are analyzing the Nitrogen levels in algae to see where along our coastlines the cesspools are leaking most.

Coastal marine ecosystems provide critical goods and services to humanity but many are experiencing rapid degradation. The need for effective restoration tools capable of promoting large-scale recovery of coastal ecosystems in the face of intensifying climatic stress has never been greater.

The #breakfreefromplastic Movement is a global movement envisioning a future free from plastic pollution. Since its launch in 2016, more than 8,000 organizations and individual supporters from across the world have joined the movement to demand massive reductions in single-use plastics and to push for lasting solutions to the plastic pollution crisis.

The Princess Vlei restoration project Growing Conservation Communities seeks to ignite community led conservation to restore critical habitats in the Greater Princess Vlei Conservation Area. It is projected to encompass the largest community led mass-planting event in the Greater Cape Floristic Region. While planting has been happening for ten years, the scope and rigour of this restoration plan takes the process to a new level." Information about the Princess Vlei Restoration Project can also be found on the Society for Ecological Restoration website

In this episode, we're learning about coastal erosion and how it affects homes built near the shore. We explore the coastline with Hawai'i Sea Grant Extension Agent, Ruby Pap, and County of Kauai planner, Ka'aina Hull, to see what happens when buildings are put too close to the ocean compared to buildings that are set-back, allowing natural beach action and sea-level rise to occur - without damaging properties.

By using big data analysis techniques and coupling it with localised information from the internet of things, social media and citizen science, we can now visualize the ever growing imprint of climate change. This talk explores how we can draw on this diversity of knowledge to recreate a more resilient world.

As cities are increasingly challenged by rapid urbanization, population growth and the impacts of land degradation and climate change, they are in the need of finding adequate solutions for sustainable city development. As most of this development is taking place in river-side and coastal areas the rapid loss of valuable wetland ecosystems makes our cities increasingly vulnerable to the impacts of extreme weather events and climate change.
