Bangladeshi women embrace mangrove restoration as an alternative livelihood

The vast Sundarbans mangrove forests along the southern coast of Bangladesh act as a shield and protect the coastal people and their livelihoods from tropical cyclones and tidal surges. In the last couple of years, the number of mangroves in the zone has increased as the government and some NGOs have introduced programs to plant mangrove trees on the coastal embankments as protection measures. Women from coastal villages, who know the ecosystem well, have been at the forefront of these reforestation projects and have also become entrepreneurial with mangrove forest resources.

Madagascar’s mangroves are rebounding after decades of deforestation

A new analysis of satellite imagery dating as far back as 1972 reveals that mangroves in Madagascar are rebounding after decades of deforestation. The island’s total mangrove cover is down 8% compared with 1972, but a closer look at the data shows that the rate of loss has been declining and even reversed in the last decade. Between 2009 and 2019, Madagascar’s mangrove cover increased by 5%, with mangrove forests expanding even more in protected areas — showing that conservation efforts are working.

Deforestation in Colombia falls to lowest level in 23 years

The amount of forest loss fell from 1,235 sq km in 2022 to 792 sq km in 2023 – a 36% decrease, official figures revealed. Most of the environmental gains were in the Amazon rainforest, where the Colombian government is focusing much of its conservation efforts. The two main successes have been reaching agreements where farmers are paid to protect the land and negotiations with armed groups who are the de facto authority in deforestation hotspots.

Campesinos plant nearly a million trees in deforestation hotspot in the Colombian Amazon

More than 700 campesinos from the municipality of Cartagena del Chairá have started restoring more than 11,000 acres of degraded rainforest in one of Colombia’s deforestation hotspots. In collaboration with researchers from SINCHI, the Amazonian Scientific Research Institute, and the Association of Community Action Boards, the families have recorded more than 600 plant and more than 100 animal species in the area.

Uzbekistan plants millions of acres of forest where the Aral Sea once lay

Instead of trying to restore what used to be the world’s third largest lake, officials from the Uzbekistan Forestry Agency and locals are trying to plant a new forest where it once rested. The main purpose of the afforestation project it to curb the harmful sandstorms and improve the ecosystem by planting desert-tolerant plants. The initiative has so far planted 4.2 million acres of forest, with up to 494,000 acres of new forest planned for 2024.

‘Absolute miracle’ breakthrough provides recipe for zero-carbon cement

Concrete is the world’s most used building material, and making it is a particularly dirty business – concrete production alone is responsible for about 8% of total global CO2 emissions. But according to new research from the University of Cambridge, throwing old concrete into steel-processing furnaces not only purifies iron but produces “reactivated cement” as a byproduct. If done using renewable energy, the process could make for completely carbon-zero cement.

Microsoft signs another reforestation-based carbon removal megadeal

Microsoft and nature-based climate solutions startup re.green have announced one of the largest-ever carbon removal agreements, with Microsoft purchasing 3 million tons of carbon removal credits over a 15-year period, generated through re.green’s reforestation projects in Brazil. The deal marks the second large-scale Brazil reforestation-focused carbon removal agreement for Microsoft, following a 1.5 million ton offtake deal with Brazil-based Mombak in December 2023, forming part of the tech giant’s initiative to become carbon negative by 2030.

Democratic Republic of the Congo plants more than 800 million trees between 2019 and 2023

Ten percent of the world’s tropical forests are found in the Democratic Republic of the Congo (DRC). But the U.N.’s Food and Agriculture Organization estimates the DRC is losing 1.2 million acres of forest every year. To help address this, a Congolese government program aspired to plant 1 billion trees between 2019 and 2023, aiming to strengthen climate resilience, alleviate poverty and protect biodiversity, and achieved 90% of their goal.

The TREES program has planted tens of millions of trees across Africa since 2015

Since it was founded in 2015, the Trees for the Future (TREES) mass reforestation campaign has convinced and enabled thousands of farmers to plant tens of millions of trees every year. The program spans nine African countries ranging from Senegal and Mali to Tanzania and Kenya. In less than 10 years, it has reportedly restored a combined area of more than 41,000 hectares, which is about seven times the size of Manhattan.

The Dominican Republic reforests a fifth of the country in 10 years

Plan Yaque, founded in 2009, brings together 30 organizations to conserve the Yaque River basin, the Dominican Republic’s lifeline. The plan’s simplicity rests in convincing landowners that reforestation is not only an ecological need but also beneficial to their well-being. By 2019, Plan Yaque and other environmental efforts have restored 18 percent of damaged land, ranking as Latin America’s second-largest land recovery.
