Download or read book Adaptation of Silkworm to Different Ecology of Nepal written by Narahari Prasad Ghimire and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relatively harder and high production potential silkworms suitable to different ecological domains are necessary for sericulture enterprise, a farm based labor intensive agro-enterprise. The climatic data proves that mid-hill has favorable agro-eco-climate for mulberry based bivoltine sericulture. This book explores the adaptability of bivoltine silkworm pure breed and hybrid genotypes to different ecological domains through different experiments including seven ecological domains, two pure breeds and five hybrids. Based on performance through multi-location testing over years, the book finish off the suitable ecological domains for pure breeds (J12 and C12) as Pokhara and Dhunibesi, while for hybrids as Khopasi and Pokhara (J12xC12) and Dhunibesi (N109xN112). The book recommends focusing future research and development in this discipline to concentrate seed cocoon production on highly productive and low mortality ecological domains and assess best performing silkworm hybrids for quality cocoon with better economic returns. The information is useful for sericulturists, professionals working in the field of Entomology and students studying Entomology, specifically the sericulture."

Download or read book Industrial Entomology written by Omkar and published by Springer. This book was released on 2017-02-13 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of writings focused on conventional and unconventional insect products. Some of these products are commercials successes, while others are waiting to be launched and are the potential produce of the future. In addition to the well known products honey, mulberry silk, and lac, the book primarily concentrates on silk producing insects other than the mulberry silkworm, insects as food, as sources of medicines, pest and weed managers, and as pollinators. The book highlights the all pervasive role of insects in improving human lives at multiple levels. Accordingly, while most books on insects concentrate on how to limit growth in their population, it instead focuses on how to propagate them. In each chapter, the book brings to the fore how insects are far more beneficial to us than their well publicised harmful roles. This book approaches both unconventional and conventional insect products, such as honey, silk and lac in much more depth than the available literature. It investigates different aspects of the production of these insects, such as the related processes, problems and utilities, in dedicated chapters. Because this book deals with the production of insects or their produce, it has been named Industrial Entomology, perhaps the only book that truly reveals the tremendous potential of insects to help humans live better lives. Based on the research and working experience of the contributors, who are global experts in their respective fields, it provides authentic, authoritative and updated information on these topics. The book offers a unique guide for students, teachers, policy planners, small scale industrialists, and government ministries of agriculture and industry across the globe. It will provide a much required stimulus to insect appreciation and generate enthusiasm for research and the broader acceptance for insect produce. Hopefully, it will also present the Indian perspective on these topics to a global readership.
Download or read book Biodiversity written by R C Sobti and published by CRC Press. This book was released on 2022-12-30 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "biodiversity" or "biological diversity" describes the variety of living beings on Earth encompassing microorganisms, plants, animals, and ecosystems, such as coral reefs, forests, and deserts. In fact, it also represents a wealth of biological resources available to us. Today, instead of exploring and preserving its unmapped biodiversity, mankind has gone away from mother nature, conquering the domain through relentless exploitation. This has resulted in an ecological imbalance and thereby has posed serious threat to biodiversity. Declining biodiversity is, therefore, a concern for countless reasons. Biodiversity’s wealth of genetic information can be conserved by storing biological material from endangered species. Cell lines, gametes, and embryos are preserved so that in case a species becomes extinct or there is a need to increase the population of the species, then cloning and artificial reproductive techniques can be used to revive and reproduce the said species. The present volume discusses the biodiversity of specific animal groups, such as cnidarians and fish, as well as potential risks to and methods for conserving some of them. The following important aspects are addressed: 1. The importance of biodiversity in maintaining ecosystem balance for sustainability 2. The emerging role of biodiversity as a source of important materials, pharmaceuticals, food, and so on as such or through genetic manipulation to meet the contemporary and future challenges 3. The impact of environment degradation on biodiversity and conservation in a changing environment 4. Conventional and emerging biotechnological techniques to conserve biodiversity The book is intended for academics, scientists, and naturalists working in the fields of biology, biochemistry, biophysics, and biomedical sciences.
Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Download or read book Gender and Natural Resource Management written by Bernadette P. Resurreccion and published by Routledge. This book was released on 2012-05-31 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the gender dimensions of natural resource exploitation and management, with a focus on Asia. It explores the uneasy negotiations between theory, policy and practice that are often evident within the realm of gender, environment and natural resource management, especially where gender is understood as a political, negotiated and contested element of social relationships. It offers a critical feminist perspective on gender relations and natural resource management in the context of contemporary policy concerns: decentralized governance, the elimination of poverty and themainstreaming of gender. Through a combination of strong conceptual argument and empirical material from a variety of political economic and ecological contexts (including Cambodia, China, Indonesia, Malaysia, Nepal, Thailand and Vietnam), the book examines gender-environment linkages within shifting configurations of resource access and control. The book will serve as a core resource for students of gender studies and natural resource management, and as supplementary reading for a wide range of disciplines including geography, environmental studies, sociology and development. It also provides a stimulating collection of ideas for professionals looking to incorporate gender issues within their practice in sustainable development. Published with IDRC.
Download or read book Mountain agriculture Opportunities for harnessing Zero Hunger in Asia written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-08-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain food security and nutrition are core issues that can contribute positively to the achievement of the Sustainable Development Goals but paradoxically are often ignored in Zero Hunger and poverty reduction-related agenda. Under the overall leadership of José Graziano da Silva, the Former Director-General of FAO, sustainable mountain agriculture development is set as a priority in Asia and the Pacific, to effectively address this issue and assist Member Countries in tackling food insecurity and malnutrition in mountain regions. This comprehensive publication is the first of its kind that focuses on the multidimensional status, challenges, opportunities and solutions of sustainable mountain agriculture development for Zero Hunger in Asia. This publication is building on the ‘International Workshop and Regional Expert Consultation on Mountain Agriculture Development and Food Security and Nutrition Governance’, held by FAO RAP and UIR in November 2018 Beijing, in collaboration with partners from national governments, national agriculture institutes, universities, international organizations and international research institutes. The publication provides analysis with evidence on how mountain agriculture could contribute to satisfying all four dimensions of food security, to transform food systems to be nutrition-sensitive, climate-resilient, economically-viable and locally adaptable. From this food system perspective, the priority should be given to focus on specialty mountain product identification (e.g. Future Smart Food), production, processing, marketing and consumption, which would effectively expose the potential of mountain agriculture to contribute to Zero Hunger and poverty reduction. In addition, eight Asian country case studies not only identify context-specific challenges within biophysical-technical, policy, socio-economic and institutional dimensions.

Download or read book Governing Africa s Forests in a Globalized World written by Laura Anne German and published by Routledge. This book was released on 2009-12-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries around the world are engaged in decentralization processes, and most African countries face serious problems with forest governance, from benefits sharing to illegality and sustainable forest management. This book summarizes experiences to date on the extent and nature of decentralization and its outcomes - most of which suggest an underperformance of governance reforms - and explores the viability of different governance instruments in the context of weak governance and expanding commercial pressures over forests. Findings are grouped into two thematic areas: decentralization, livelihoods and sustainable forest management; and international trade, finance and forest sector governance reforms. The authors examine diverse forces shaping the forest sector, including the theory and practice of decentralization, usurpation of authority, corruption and illegality, inequitable patterns of benefits capture and expansion of international trade in timber and carbon credits, and discuss related outcomes on livelihoods, forest condition and equity. The book builds on earlier volumes exploring different dimensions of decentralization and perspectives from other world regions, and distills dimensions of forest governance that are both unique to Africa and representative of broader global patterns. The authors ground their analysis in relevant theory while drawing out implications of their findings for policy and practice.
