Fisheries Act

Fish habitat is essential to the stability and productivity of fisheries. In Canada, the primary legal tool for protecting fish habitat is the federal Fisheries Act. In 2012, this law was changed to narrow the scope of habitat protection. The government’s position was that the previous regime went beyond what was necessary to protect fish and fish habitat. Here, we tested that assertion by examining Fisheries Act authorizations to harmfully alter, disrupt, or destroy fish habitat issued by Fisheries and Oceans Canada during a 6-month period in 2012, obtained using access to information processes. We found the majority of projects (67%) were authorized to impact more habitat than proponents were required to compensate for, likely resulting in a net loss of fish habitat. Our analysis show an aggregate net loss — defined as authorized impact minus required compensation — of 2 919 143 m2 authorized across 78 projects. Drawing from these results, we present four recommendations for an improved habitat protection regime under a renewed Fisheries Act, emphasizing the need to establish a public registry for authorizations and monitoring data.

Abstract Assessing fish habitability in pursuance of damming for some selected fishes in wetland of Indo-Bangladesh barind tract using hydrological ingredients like hydro-period, water depth, and water presence consistency is major focus of the present study. Rule based decision tree modeling has been applied for integrating aforesaid hydrological parameters to find out habitat suitability for some selected fishes like carp fishes, shrimps, tilapia and cat fishes both for pre-dam and post-dam periods. From this work it is highlighted that damming has accelerated the rate of wetland deterioration in forms of hydrological flow alteration i.e. inconsistency in water presence has increased, hydro-duration became shortened and water depth has attenuated. From the model it is very clear that a small proportion area was considered to be good fish habitat (16.54–39.90%) in pre-dam period, but after damming almost all parts have become least suitable for fish habitability. Field survey has confirmed that fishing quantity, growing rate of fishes was higher in pre-dam situation but it is reduced gradually during post-dam period. Image driven hydrological parameters to model fish habitability is a new approach but important parameters like food availability, water quality parameters could also be incorporated in order to get better result.

Populism has become a pervasive concept in political science research. However, a central and basic question remains unanswered: which European parties are more populist than others? Despite the increasing wealth of studies on populism in parties, we lack data that measures populism in political parties in a valid and precise manner, that recognizes that populism is constituted by multiple dimensions, and that ensures full coverage of all parties in Europe. In this article, we first appraise the weaknesses of existing approaches. Arguing that parties’ populism should be measured as a latent construct, we then advocate a new approach to operationalizing and measuring populism in political parties using expert surveys. Relying on the Populism and Political Parties Expert Survey spanning 250 political parties in 28 European countries, we show that populism is best measured in a multi-dimensional and continuous manner. We subsequently illustrate the advantages of our approach for empirical analysis in political science.

Local Agencies

Successful fish habitat protection occurs in areas of urban/industrial development when responsible citizens in rural watersheds can produce and implement local water quality plans binding on all agencies. In 1985, legislation in the state of Washington, USA, authorized a central planning agency — the Puget Sound Water Quality Authority — to initiate local watershed planning exercises through counties or other local agencies. The essential elements of community mobilization to the goals and activities of water quality planning were analyzed by comparing key factors in highly successful planning processes with factors in less successful ones. This permitted generalizations about basic organizing principles, educational procedures, and techniques of consensus building in the planning and implementation of water quality rehabilitation and protection for watersheds. The analysis contributed to a general theory of how and why community participation can improve the effectiveness of fish habitat protection.

In this article the authors develop a new approach to the study of policy dynamics in a quasi-federal system of government. The goal is to contribute to previous research on comparative federalism by analyzing the variations of issue attention between levels of government and across four regional governments—Andalusia, Catalonia, Galicia, and the Basque Country. To do so the authors follow the policy dynamics approach, developing a comparative and empirical analysis about issue attention across time, territories, and policy subsystems. The analysis relies on an extensive database, created following the methodology of the Comparative Agendas Project, which includes all laws passed from the early 1980s to present. The results indicate that legislative agendas have become increasingly diverse since the 1990s, and this is partly explained by party preferences and the type of government.
