Despite receiving international support for training and financing, Ecuador's integrated coastal zone management (ICZM) faces significant challenges due to economic and administrative instability. This study highlights that such discontinuities hinder the development of tourism and economic growth in coastal areas, including the Galápagos Islands. The research analyzed ten key elements—policies, regulations, institutions, strategies, instruments, information, education, resources, managers, and participation—to assess national coastal management. Findings suggest that while Ecuador has made progress, sustained efforts are needed to strengthen gastronomic and cultural aspects in new policies to overcome these obstacles.

A study integrating local ecological knowledge (LEK) into wildlife population monitoring found that LEK-informed methods provided estimates of species occupancy comparable to camera trap data at the village level, though with species-specific differences. The research, conducted in two wild meat hunting villages adjacent to Cameroon's Dja Faunal Reserve, used a mixed-method approach—including daily hunter diaries, seasonal interviews, and camera traps—to triangulate data and identify sources of uncertainty. It revealed that geographical characteristics, hunter methods, and motivations influenced species depletion patterns. Additionally, the study highlighted gender as a predictive factor in knowledge type and noted that local experts did not always provide the most robust estimates. The findings underscore the potential of LEK for cost-effective monitoring but caution against overestimating its reliability without accounting for logistical and financial constraints.

New radiometric dating of the Drimolen Palaeocave System in South Africa's UNESCO-listed Fossil Hominid Sites reveals critical insights into early hominin evolution. The Main Quarry deposits, yielding Paranthropus robustus remains and bone tools, are dated to 1.712 ± 0.269 million years ago (Ma), aligning with biochronological estimates for the Swartkrans Member 1 Hanging Remnant. A nearby deposit, Drimolen Makondo, discovered in 2013, is older at 2.706 ± 0.428 Ma, predating the Main Quarry and overlapping with the end of Australopithecus-bearing Sterkfontein deposits. This challenges prior age estimates, suggesting the Drimolen site records a pivotal hominin and faunal turnover around 2.3–1.7 Ma. The study also integrates cave levels across the Malmani dolomite, revealing that older caves are likely eroded away, explaining the scarcity of pre-2 Ma deposits in this region.

A novel approach combining participatory mapping with remote sensing reveals the significant decline of ecosystem services (ES) in the Lower Omo Valley, Ethiopia, following regional environmental changes such as the construction of the Gibe III dam. The study highlights the collapse of flood-retreat cultivation and substantial reductions in shrubland and wetland areas, both critical for local communities. By integrating Traditional Ecological Knowledge (TEK) with satellite imagery, researchers demonstrate how this mixed-methods approach can provide locally relevant insights into ES dynamics. The findings underscore the importance of incorporating TEK to improve resource management strategies, offering a scalable model for other regions.
