Book Description
From its crude and uneasy beginnings thirty years ago, Chinese sperm banking has become a routine part of China’s pervasive and restrictive reproductive complex. Today, there are sperm banks in each of China’s twenty-two provinces, the biggest of which screen some three thousand to four thousand potential donors each year. Given the estimated one to two million azoospermic men--those who are unable to produce their own sperm--the demand remains insatiable. China’s twenty-two sperm banks cannot keep up, spurring sperm bank directors to publicly lament chronic shortages and even warn of a national ‘sperm crisis’ (jingzi weiji). Good Quality explores the issues behind the crisis, including declining sperm quality in the country due to environmental pollution, as well as a chronic national shortage of donors. In doing so, Wahlberg outlines the specific style of Chinese sperm banking that has emerged, shaped by the particular cultural, juridical, economic and social configurations that make up China’s restrictive reproductive complex. Good Quality shows how this high-throughput style shapes the ways in which men experience donation and how sperm is made available to couples who can afford it.

Book Description
This book comprehensively describes essential research and projects on climate change and biodiversity. Moreover, it includes contributions on how to promote the climate agenda and biodiversity conservation at the local level. Climate change as a whole and global warming in particular are known to have a negative impact on biodiversity in three main ways. Firstly, increases in temperatures are detrimental to a number of organisms, especially those in sensitive habitats such as coral reefs and rainforests. Secondly, the pressures posed by a changing climate may lead to sets of responses in areas as varied as phenology, range and physiology of living organisms, often leading to changes in their lifecycles (especially but not only in reproduction), losses in productivity or even death. In some cases, the very survival of very sensitive species may be endangered. Thirdly, the impacts of climate change on biodiversity will be felt in the short term with regard to some species and ecosystems, but also in the medium and long term in many biomes. Indeed, if left unchecked, some of these impacts may be irreversible. Many individual governments, financial institutes and international donors are currently spending billions of dollars on projects addressing climate change and biodiversity, but with little coordination. Quite often, the emphasis is on adaptation efforts, with little emphasis on the connections between physio-ecological changes and the lifecycles and metabolisms of fauna and flora, or the influence of poor governance on biodiversity. As such, there is a recognized need to not only better understand the impacts of climate change on biodiversity, but to also identify, test and implement measures aimed at managing the many risks that climate change poses to fauna, flora and micro-organisms. In particular, the question of how to restore and protect ecosystems from the impact of climate change also has to be urgently addressed. This book was written to address this need. The respective papers explore matters related to the use of an ecosystem-based approach to increase local adaptation capacity, consider the significance of a protected areas network in preserving biodiversity in a changing northern European climate, and assess the impacts of climate change on specific species, including wild terrestrial animals. The book also presents a variety of case studies such as the Yellowstone to Yukon Conservation Initiative, the effects of climate change on the biodiversity of Aleppo pine forest in Senalba (Algeria), climate change and biodiversity response in the Niger Delta region, and the effects of forest fires on the biodiversity and the soil characteristics of tropical peatlands in Indonesia. This is a truly interdisciplinary publication, and will benefit all scholars, social movements, practitioners and members of governmental agencies engaged in research and/or executing projects on climate change and biodiversity around the world.
