The United Republic of Tanzania (Tanzania) is rich in freshwater resources and biodiversity. In this article, we highlight the importance of Tanzanian rivers and make a case for the conservation of the freshwater and terrestrial species that rely on these rivers. We provide an overview of current knowledge on Tanzanian rivers and discuss progress towards implementation of the National Water Policy (2002) and Water Management Act (2009), two legislative instruments that have motivated environmental flow assessments on at least six major rivers and offer legal backing for river conservation. We examine major challenges that pose significant threats to water security for river ecosystems and humans in Tanzania, among those: (1) human population growth, (2) agricultural expansion, (3) river flow alterations, (4) industrialization, (5) introduced species, and (6) climate change. We conclude by offering recommendations for future river conservation efforts in Tanzania.

The Everglades of south Florida, although degraded, imparts vital ecosystem benefits, including contributions to high quality drinking water supplies and habitat for a number of threatened and endangered species. Restoration of the Everglades can improve the provision of these benefits but also may impose tradeoffs with competing societal demands. This study focuses on understanding public preferences for Everglades restoration and estimating the willingness to pay (WTP) values for restored ecosystem services (ES) through the implementation of a discrete choice experiment (DCE). We collected data from 2302 respondents from the general public from an online survey designed to elicit WTP values for selected ecological and social attributes associated with Everglades restoration scenarios. We compare the findings to results from earlier studies (Milon et al., 1999; Milon and Scrogin, 2005), which also estimated WTP values among Floridians for Everglades restoration. For some attributes, WTP for Everglades restoration appears to have slightly increased while for others WTP appears to have decreased. We estimated statewide aggregate WTP values for components of species population restoration up to $2B over 10 years. Several factors impeded a direct comparison of the current and historical WTP values, including the time elapsed, different samples, and sampling methods-which may have implications on long term efforts to integrate certain social science analyses into water resources management.
