Experts on the environment have called on African governments to entirely reject Geoengineering Technology to protect local communities against the adverse effects at COP 28.

The experts from Friends of the Earth Africa and Environmental Rights Action/ Friends of the Earth Nigeria (ERA/FoEN) spoke on Wednesday.

On Climate Justice, Mr Maimoni Ubrei-Joe, Campaigner with ERA/FoEN and Friends of the Earth Africa noted that geoengineering does not have the solution to climate change.

The environmentalist stated that climate geoengineering is one of the many false solutions that have been proposed to counter the path to a just energy transition.

Geoengineering involves large-scale schemes for intervention in the earth’s oceans, soils and atmosphere, with the aim of providing a temporary reduction of the effects of climate change.

According to him, some of geoengineering techniques such as Solar Radiation Management (SRM) seeks to alter the amount of sunlight reaching the earth’s surface and could lead to regional climate changes.

“Solar Radiation Management is the altering of the amount of sunlight reaching the earth’s surface, which could lead to regional climate changes.

“This could result in shifts in precipitation patterns, temperature extremes, and changes in agricultural productivity, which could negatively impact local communities.

“These are people that rely on stable and predictable climate conditions for farming, water availability, and livelihoods.

“Modifying cloud patterns or introducing reflective particles into the atmosphere may have unintended consequences for local ecosystems.

“Changes in sunlight and temperature regimes could disrupt ecosystems, leading to shifts in species composition, altered migration patterns, and potential biodiversity loss.”

Ubrei-Joe further revealed that Carbon Dioxide Removal (CDR), a large-scale implementation of techniques such as afforestation or creating artificial forests, which may require a large expanse of land.

The environmentalist noted that this could create the struggle for land resources by local communities.

“This has the potential of displacing local communities and forcing them to encroach on indigenous territories, or disrupting traditional land uses and livelihoods.

“Some CDR methods, like ocean fertilisation, may carry environmental risks.

“For instance, seeding the ocean with iron pellets to stimulate plankton blooms can alter marine ecosystems, affecting fish populations and potentially disrupting local fishing industries or coastal communities dependent on marine resources,” he said.

He explained that Earth Radiation Management, another artificial technique that involves the thinning of cirrus clouds to allow more heat to escape into space.

He said that the method creates changes to cloud cover and atmospheric dynamics could lead to volatile shifts in local weather patterns.

The act he explained, will make it challenging for communities, especially farmers to adjust and plan for changes effectively.

He explained that geoengineering projects are often global or national in scale.

The environmentalist regretted that decision-making processes may not adequately involve or consider the perspectives and concerns of local communities.

According to the environmentalist, the process undermines social equity and justice, potentially exacerbating existing social and economic inequalities.”

Also Chima Williams, Executive Director of ERA/FoEN, maintained the geoengineering has enormous human rights impact and implications.

He explained that Solar Radiation Management techniques such as spraying sulphates into the stratosphere or modifying clouds, may have unintended and unpleasant consequences.

It will cause infringement on the right to health and the right to water, while Carbon Dioxide Removal methods involving large-scale carbon capture in the atmosphere, also raises human rights concerns in relation to food, livelihood, land and indigenous rights.

He further added that the Earth Radiation Management technique is an infringement on the right to self-determination and the right to adequate standard of living.

Williams called for the reduction of the emissions of greenhouse gases, as it is the safest way to rescue the world from the negative impacts of climate change which is the goal that every sector must pursue without compromise.

“A search on efforts being made to address the climate crisis will produce shocking results that shows that all sectors including the most polluting sectors also claim to be involved in fighting climate change.

“This deception is targeted at dodging the real solutions which essentially is about cutting emissions to zero by leaving fossil fuel in the soil, coal in the ground and tar sand in the hole and adopting renewable energy sources.”
