Global growth in aquaculture is underway – a “blue revolution” featuring rapid increases in demand for fish and a corresponding surge in aquaculture production. This paper describes the fast-growing tilapia value chain in Ghana to demonstrate the features of a nascent blue revolution in sub-Saharan Africa (SSA) and to illustrate its potential for job creation and reducing poverty and food insecurity there. Tilapia production has been growing at 15 percent annually in SSA, but imports are also surging to satisfy the growing appetite for tilapia. This paper illustrates how aquaculture can grow sustainably in SSA within the context of growing demand and global competition. A value chain analysis is conducted using secondary data analysis, desk reviews of experiences and lessons from other countries, interviews with 95 actors in the tilapia value chain in Ghana, and detailed production and profitability data from Ghanaian tilapia farmers. A profitable farmed tilapia industry has been established in Ghana with the potential to expand supply to satisfy local demand and to export to neighboring countries. Productivity in the industry has grown mainly through reducing the mortality rates of fingerlings and improvements in the supply of locally-produced high-quality fish feed. Feed costs remain high. However, there is potential to reduce those costs by improving the productivity of crops that are used in fish feed, particularly maize and soybean. Reducing local feed costs will have positive spillover effects on both other pond-based aquaculture systems and on the livestock feed sector. Moreover, Ghana can expand it fish feed production to be an important source of feed within SSA. The industry can further increase aquaculture productivity through the adoption of faster-growing fish strains and better management practices. Ghana’s aquaculture sector could grow even faster by adopting lessons from other countries, including on infrastructure provision, fiscal incentives for the production of fish feed ingredients, and sustainable fish farming practices, particularly through paying close attention to water and feed quality and addressing food safety concerns within the sector.

This book presents a powerful and thorough investigation into police deviance and sexual misconduct in the US. Drawing on news reports, official government press releases and academic research sources, Barker examines a wide array of cases including sexual harassment, sexual abuse, child molestation and police killings, including those of prisoners behind bars. Substantiated with additional cases from the UK, Russia and beyond, analysis is also conducted of the experiences of the victims of those crimes. Aggressors in Blue argues that this misconduct has its roots in the nature of the law enforcement occupation, and outlines the typical conditions which enables police sexual abuse to take place. This is a bold new investigation which speaks to students and academics in criminal justice, criminology and social justice in particular, as well as to scholars, social justice advocates, law enforcement professionals, policy-makers and academics in other related disciplines.

Blue in Old English represents the first thorough investigation of an area of the colour semantics of Old English, and the methodology developed for this study is believed to be appropriate for researching the colour semantics of any language which survives only in recorded texts. By means of a collection of in-depth word-studies, which suggest new interpretations of many well-known passages, an understanding of how blueness was described in Old English is developed. The approach is interdisciplinary, using evidence from subjects such as botany, manuscript illustration, etymology, early technologies, and others. The conclusion contradicts certain previously held views on Old English colour, and presents a hitherto obscured sociolinguistic picture of differing language use among various groups of Old English speakers.

A landmark book by marine biologist Wallace J. Nichols on the remarkable effects of water on our health and well-being. Why are we drawn to the ocean each summer? Why does being near water set our minds and bodies at ease? In Blue Mind, Wallace J. Nichols revolutionizes how we think about these questions, revealing the remarkable truth about the benefits of being in, on, under, or simply near water. Combining cutting-edge neuroscience with compelling personal stories from top athletes, leading scientists, military veterans, and gifted artists, he shows how proximity to water can improve performance, increase calm, diminish anxiety, and increase professional success. Blue Mind not only illustrates the crucial importance of our connection to water; it provides a paradigm shifting "blueprint" for a better life on this Blue Marble we call home.
