A review of conservation projects worldwide has found that conservation efforts have had a positive and significant impact. The study analyzed 665 trials dating back to the 19th century and found that in two-thirds of cases, conservation either improved biodiversity or halted declines. Successful approaches included farmland schemes, invasive species control, and the establishment of protected areas and indigenous lands. However, some measures had unintended consequences, emphasizing the need for caution and consideration of secondary species. The study also highlighted the importance of measuring impact and learning from failures. A recent report calls for increased funding and action in conservation efforts, particularly in the Global South. The study shows that conservation actions are successful but need to be scaled up to meet global targets. Combining multiple approaches, such as protected areas, payments for environmental services, and invasive species eradication, has proven to be effective. However, current funding for conservation is insufficient, representing only 0.25% of global GDP. Addressing the underlying causes of biodiversity loss, such as unsustainable production and fossil fuel subsidies, is crucial. National leaders must demonstrate political will and prioritize conservation efforts to reverse biodiversity loss. The report provides hope that it is not too late to act, but urgent action is needed. [Extracted from the article]
