Lake Erie's green monster: Climate change adds pressure to prevent toxic algal blooms

Climate change has led to shorter, more violent rainy seasons in the highlands around Lima, Peru, meaning that - even though there is theoretically enough water during the rainy season to sustain the local population, it flows downhill too quickly, leaving residents short of clean water during the dry season. Now, an organization called Condesan is helping the community to restore ancient stone canals from the seventh century that will help to store water from rainfall through the dry season and supply residents with a steady water source.

As Tucson works to combat the effects of climate change, the Arizona city has been implementing policies to conserve its limited water supply through initiatives like a city rebate program. By focusing efforts on water harvesting — both rainwater, which can be drinkable, and stormwater, which can be used for irrigation — the city can use that water to create more green spaces and lower water bills. The rebate program pays back residents as much as $2,000 for purchasing water harvesting systems. During one year, the program saved 52.1 million gallons of water, which is enough for 160 households.

New solar-powered irrigation systems in the Chotanagpur Plateau region in India are giving farmers more dependable water and allowing them to diversify their crops, allowing them to also grow their income. Many farmers from a local village used to migrate to other places to search for work, but a new irrigation system has allowed them to grow cauliflower for a competitive price. While the cost of buying and installing a solar-powered irrigation system can be high, this form of irrigation could be more climate-friendly and help stabilize crop production.

Confronting more frequent heavy rains, the state's farmers have extended farmland drainage. Higher crop yields is one result. Another: More dirty water is flowing downstream.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.

El Paso pecan farmers are implementing innovative water conservation techniques—including cover crops, polymer soil treatments, and improved tillage practices—that are showing promising results in reducing water usage and salt buildup, with cover crops alone reducing weed populations by 80-90% while creating cooler, more moisture-retentive soil conditions that help orchards survive in increasingly drought-prone conditions.

Ranchers and conservationists in Florida are working together to lobby for policies that preserve their farmland, protect wildlife species, and conserve water instead of turning it over to be developed. The Sunshine State has experimented with conservation incentive programs like payments for panther habitat restoration, reimbursements for livestock losses, and water storage projects but most of these programs have had mixed success and are often underfunded.

The effects of climate change, such as rising sea levels and hotter global temperatures, are already having drastic impact on many communities, especially the rural, agricultural regions of countries such as Myanmar (formerly Burma) and Mozambique. Earthrise explores how people in these communities are learning new skills, implementing new techniques, and are striving in every way possible to adapt to these environmental changes while creating hope for sustainable growth in the future.

An AI-powered underwater sensor system developed by KMFRI and ShoShin Innovation Hub detects dangerous drops in dissolved oxygen in Lake Victoria and sends SMS alerts to fish farmers. This enabled them to move their cages in time and successfully averting a mass fish kill in February 2026 that would have threatened hundreds of tilapia cages at Dunga Beach.

Artificial mangrove roots or AMRs, developed by Thailand scientists are being installed on the country’s beaches to mimic mangrove’s sediment trapping abilities. These wood and rubber structures can help reverse coastal erosion, reclaim the land and help in restoring natural mangrove forests.
