Local initiatives in Ethiopia’s Abijata-Shalla National Park, funded by the Swedish International Development Cooperation Agency, are successfully restoring ecosystems through sustainable land management practices. These efforts involve significant participation from women and local communities, enhancing tree cover and improving lake water levels while also addressing erosion. In Peru, restoration projects in the Polylepis forests, led by organizations such as Instituto de Montaña and ECOAN, focus on protecting existing forests and restoring degraded pastures, aiming to rejuvenate 1 million hectares of native Andean forests by 2045. These initiatives are deeply rooted in community engagement and traditional conservation agreements, particularly with Indigenous Quechua people, fostering biodiversity and enhancing livelihoods.

On the technological front, a study from UC San Diego and Princeton University demonstrates the effectiveness of combining clean energy subsidies with pollution taxes to drive greenhouse gas emissions reductions. Meanwhile, Saudi Arabia’s completion of a 7.8 gigawatt-hour battery energy storage system, owned by Saudi Electricity Co. and supported by an offtake deal with National Grid SA, represents a significant step towards sustainable energy. This system is expected to supply power to 400,000 households annually, highlighting its potential impact on the region’s energy landscape amidst ongoing fossil fuel dependency.
