Pre-calculated LCI systems with uncertainties cannot be used in comparative LCA

Letter to the editor: A recent paper by Qin and Suh (2016) provides an interesting test of the assumption of lognormally distributed life cycle inventory (LCI) results. We appreciate the importance of this work, and acknowledge that finding out this result must have taken a long computation time. In that respect, we would like to comment on the remark in section 4 that “conducting uncertainty analysis from the unit process level is neither time-efficient nor necessary for most studies.

Biochemical impacts of salinity on the catfish, Heteropneustes fossilis (Bloch, 1794), and possibility of their farming at low saline water

Although a stenohaline freshwater fish, the stinging catfish Heteropneustes fossilis, is also available in the freshwater fringes of the coastal areas of Bangladesh, the tolerance of this species to variable environmental salinity has not been thoroughly investigated. This study aims to understand salinity tolerance level by monitoring the growth, survival and biochemical parameters of H. fossilis under different salinity exposure for a period of 90 days.

Identification of Tilapia Lake Virus in Egypt in Nile tilapia affected by ‘summer mortality’ syndrome

Egyptian fish farms have faced unexplained mortality of tilapia during the summer months in recent years. Epidemiological surveys indicated that 37% of fish farms were affected in 2015 with an average mortality rate of 9.2% and a potential economic impact of around US$ 100 million. Despite a number of researchers and organizations investigating potential causes results so far have been inconclusive. The aim of this study was to identify the effect of various production factors on the incidence of disease outbreaks in Egyptian pond based aquaculture.

Nutrition-sensitive landscapes: Approach and methods to assess food availability and diversification of diets

Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems.

Integrated systems research in nutrition-sensitive landscapes: A Theoretical methodological framework

Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems.

Exploring futures of Aquatic Agricultural Food Systems in Southern Africa: From drivers to future-smart research and policy options

Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems.

Does sustainable intensification offer a pathway to improved food security for aquatic agricultural system-dependent communities?

Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems.

Rotational zoning systems in multi-species sea cucumber fisheries

Rotational zoning systems (RZSs) have been applied as a spatial management tool for fisheries in developed countries. Fishing grounds are divided into numerous plots and assigned a cyclical periodicity for harvest. This is a distinct spatial management measure that differs from more common measures in the tropics, like periodic closures or marine protected areas. We find that biological prerequisites for rotational closures are tenuous for many tropical reef species, and they are likely to put stocks of threatened species at further risk.
