Lake sediments constitute natural archives of past environmental changes. Historically, research has focused mainly on generating regional climate records, but records of human impacts caused by land use and exploitation of freshwater resources are now attracting scientific and management interests. Long-term environmental records are useful to establish ecosystem reference conditions, enabling comparisons with current environments and potentially allowing future trajectories to be more tightly constrained. Here we review the timing and onset of human disturbance in and around inland water ecosystems as revealed through sedimentary archives from around the world. Palaeolimnology provides access to a wealth of information reflecting early human activities and their corresponding aquatic ecological shifts. First human impacts on aquatic systems and their watersheds are highly variable in time and space. Landscape disturbance often constitutes the first anthropogenic signal in palaeolimnological records. While the effects of humans at the landscape level are relatively easily demonstrated, the earliest signals of humaninduced changes in the structure and functioning of aquatic ecosystems need very careful investigation using multiple proxies. Additional studies will improve our understanding of linkages between human settlements, their exploitation of land and water resources, and the downstream effects on continental waters.
Vietnam is struggling to meet the growing need for both disease-modifying and palliative care for people with life-threatening chronic diseases such as HIV/AIDS and cancer. Recently, Vietnam initiated rapid development of a national palliative care program for HIV/AIDS and cancer patients that builds on existing palliative care programs and experience and integrates palliative care into standard HIV/AIDS and cancer care. National palliative care guidelines have been issued by the Ministry of Health based on a rapid situation analysis. Plans now call for review and revision of opioid laws and regulations to increase availability of opioids for medical use, training in palliative care for clinicians throughout the country, and development of palliative care programs both in the community and in inpatient referral centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
