Does the creation of artificial reefs benefit subtidal benthic invertebrates? Is the use of organic farming instead of conventi onal farming beneficial to bat conservation? Does installing wildlife warning reflectors along roads benefit mammal conservation? Does the installation of exclusion and/or escape devices on fishing nets benefit marine and freshwater mammal conservation? What Works in Conservation has been created to provide practitioners with answers to these and many other questions about practical conservation. This book provides an assessment of the effectiveness of 2526 conservation interventions based on summarized scientific evidence. The 2021 edition contains substantial new material on bat conservation, terrestrial mammal conservation and marine and freshwater mammals, thus completing the evidence for all mammal species categories. Other chapters cover practical global conservation of primates, amphibians, birds, forests, peatlands, subtidal benthic invertebrates, shrublands and heathlands, as well as the conservation of European farmland biodiversity and some aspects of enhancing natural pest control, enhancing soil fertility, management of captive animals and control of freshwater invasive species. It contains key results from the summarized evidence for each conservation intervention and an assessment of the effectiveness of each by international expert panels. The accompanying website www.conservationevidence.com describes each of the studies individually, and provides full references. This is the sixth edition of What Works in Conservati on, which is revised on an annual basis. As with all Open Book publications, this entire book is available to read and download for free on the publisher’s website at https://www.openbookpublishers.com/product/1490 where printed and ebook editions can also be bought.

The guidance and special techniques provided in this handbook will allow you to understand and use complex spatial statistical techniques. You will learn how to apply proper spatial analysis techniques and why they are generally different from conventional statistical analyses. Clear and concise information on weighting, aggregation effects, sampling, spatial statistics and GIS, and visualization of spatial dependence is provided. Discussions on specific applications using actual data sets fill obvious gaps in the literature, and coverage of critical research frontiers allows readers to explore current areas of active research.

India’s rice and wheat crops are in crisis – a dangerous situation for a nation where 75 per cent of the population depends on agriculture for a living. Today’s falling or static yields in these two key crops have been the result of the intensification of agriculture from the 1960s on. That so-called ‘Green Revolution’, which depended heavily on chemical fertilizers and pesticides, saw crop production keep pace with population growth until the end of the last millennium. Today, however, the sector is suffering from depleted soils and reduced ground water levels. Past excesses have even left the current generation of farmers with health hazards. The authors of this volume, experts in agriculture and agronomy in the subcontinent, say a new approach is needed. India’s population will rise from today’s 1.18 billion people to as many as 1.5 billion by 2020, with 25 per cent more mouths to feed. Not only that, but agriculture’s pre-eminent place in the country’s economy, where it is 18 per cent of total GDP and the biggest single export sector, make any problem in the industry one of national importance. Other nations in Asia, including Pakistan, Nepal, China and Bangladesh, have already recognized the problem of static yields and have developed the concept of the ‘Integrated Nutrient Management’ (INM) system. Its aim is to make agricultural cropping sustainable by maintaining or enhancing the soil quality while leaving room for increases in yields, and it advocates the balanced use of both organic and inorganic methodologies. Mahajan and Gupta, both highly experienced experts in the science of agriculture, and in Gupta’s case a leading environmentalist, examine in detail India’s cropping crisis as well as the possible remedies. They conclude that the INM System is an essential component of any solution. The book also delineates potential sources of organic plant nutrients and bio-fertilizers in India, and analyzes the rice-wheat cropping system and the role INM could play in sustaining crop productivity. The authors also provide insight into the balanced use of plant nutrients in increasing rice and wheat productivity and about the effective use of fertilizers and water management practices for rice and wheat crops. Constraints in the adoption of INM system and future research strategies are the other crucial topics which are covered in this comprehensive text.
