Changes in the Earth’s climate are expected to impact freshwater habitats around the world by altering water temperatures, water levels, and streamflow. These changes will have consequences for inland fish – those found within lakes, rivers, streams, canals, reservoirs, and other landlocked waters – which are important for food, commerce, and recreation around the world. According to the U.S. Fish and Wildlife Service, in 2011, 33.1 million people fished and spent $41.8 billion in the United States alone. Yet to date, little comprehensive research has been conducted to investigate the effects of climate change on inland fisheries at a large scale. The aim of this project was to summarize the current state of knowledge,...

A Coupled Hydrosphere Atmosphere Research Model was developed that predicted vertical water temperature profiles, ice cover, and precipitation within 40-km grids and lake levels for Lakes Huron between 2058 and 2066. In this data set, daily predicted water temperature profiles are summarized for four regions in Lake Huron (north: North of 45 degrees N; central: between 43 degrees 55 minutes N and 45 degrees N; south: south of 43 degrees 55 minutes N; south-shallow: only areas less than <40 m bottom depth and south of 43 degrees 55 minutes N). Model output was driven by the Canadian CRCM3 GCM and assumed SRES A2 scenario greenhouse gas concentrations.

This study analyzes quantitative and qualitative information and develops selected indicators of the condition of the world's freshwater systems. The condition is defined as the current and future capacity of the systems to continue providing the full range of goods and services needed or valued by humans. Where available, we use global data sets to illustrate key indicators. In cases in which global data are not available, we use regional- and national-level information to illustrate important concepts, indicators, trends, and issues. Sometimes, local-level case studies have been used to illustrate trends that appear to be important but for which national or global data do not exist.

Inland fisheries are critical for global food security and human well-being. However, fish production may be threatened by changes in climate and land use. Understanding this threat is crucial to effectively manage inland fisheries in the future. To address this need, this project will identify which types of lakes across the globe are most vulnerable to the impacts of climate and land use changes. Lakes will be categorized based on their depth, vulnerability to food insecurity, and vulnerability to water insecurity – variables which can all influence how detrimental climate and land use change will actually be on a lake. This information will be used to predict how inland fisheries production might change under...

Despite the important effects of inland fisheries on food, economy, and ecosystem services throughout the world, no comprehensive understanding on the status or key drivers of inland fisheries exists (Beard et al. 2011). Our lack of knowledge regarding the status results from the common belief that inland fishery harvests are widely under reported (FAO 2009; Welcomme et al. 2010), particularly the contributions from recreational, artisanal, and illegal fisheries (FAO 2003; Allan et al. 2005). Overcoming this knowledge gap has no simple solution, given that resources to conduct on-the-ground fisheries assessments are lacking throughout much of the world, particularly in Africa or Asia where the majority of the inland...

In one of the largest compilations of inland-lake-fisheries time series to date (31 lakes spanning five continents from 1970 to 2014), we sought to identify generalities regarding how inland fisheries respond to forecasted climate and land use changes. Perhaps not surprisingly given the diversity of inland lakes and fisheries, we reported that fish catches can either respond positively or negatively to these forecasted changes, through a variety of pathways. One key factor that positively correlated with vulnerability to a 25% reduction in fish catch was lower access to clean water. If future research can further demonstrate this linkage, it would provide a strong argument to policy makers that investments in clean...

A Coupled Hydrosphere Atmosphere Research Model was developed that predicted vertical water temperature profiles, ice cover, and precipitation within 40-km grids and lake levels for Lake Michigan between 2058 and 2066. In this data set, daily predicted water temperature profiles are summarized for four regions in Lake Michigan (north: North of 45 degrees 20 minutes N; central: between 43 degrees 30 minutes N and 45 degrees 20 minutes N; south: south of 43 degrees 30 minutes N; south-shallow: only areas less than <40 m bottom depth and south of 43 degrees 30 minutes N). Model output was driven by the Canadian CRCM3 GCM and assumed SRES A2 scenario greenhouse gas concentrations.
