Deforestation refers to the practice of clearing trees and other vegetation from an area of land, usually for commercial or agricultural purposes. This process is not only destructive to the environment but also has a significant impact on human societies and economies worldwide. Deforestation is a global issue that affects many countries, particularly those in tropical regions such as Brazil, Indonesia and the Democratic Republic of Congo. According to the World Wildlife Fund, around 17% of the Amazon rainforest has been lost in the past 50 years, while Indonesia has lost around 25 million hectares of forest since the 1990s. Deforestation not only leads to the loss of valuable natural resources, but it also contributes significantly to climate change.

Biodiversity governance refers to the policies, institutions, and processes that govern the management and conservation of biodiversity. Biodiversity governance is critical because biodiversity is essential for maintaining the balance of ecosystems and the planet's sustainability. The governance of biodiversity involves a range of stakeholders, including governments, civil society, academia, and the private sector, among others. In this essay, we will discuss the concept of biodiversity governance, its importance, and the challenges facing it.

The interaction between sedimentary processes and hydrodynamics has a significant impact on coastal habitats. Given the sensitivity and specificity of living populations or the presence of dead specimens, the assemblages of benthic foraminifera are structured by environmental factors, making them excellent indicators of the main processes in coastal settings. The present study evaluated environmental variables in beachrocks of Brazilian tropical sandy beaches using benthic foraminifera as a proxy. In order to describe foraminiferal assemblages (27 samples), as well as to conduct grain size analysis and CaCO content determination, samples were collected at the base of coastal beachrocks on the beaches Pina, Enseada, and Toquinho (northeastern, Brazil) (27 samples). Medium to coarse sand of terrestrial origin, fairly sorted and roughly symmetrical, made up the majority of the deposits. Rip currents, littoral drift and the primary forces behind the size, sorting, and redistribution of the sediments are littoral drift, rip currents, and waves. A total of 6829 foraminifera from 42 genera and 76 species were found.
