        Biodiversity and Conservation Along an East African Railway

        A Survey of the Dar es Salaam-Makutupora Standard Gauge Railway, Tanzania

        by Catherine Aloyce Masao, Joel Nobert, Flora John Magige, Edmond Alavaisha, S. Zainabu Bungwa, Philbert Anitha Byabato, Deusdedith Fidelis, Elikana John, Jasson John, Julius Mohamed Kibaja, Heriel Moshy, Athumani Fatina Mturi, R. Juma Mwangi, Henry Ndangalasi, Wilrik Ngalasoni, Alberto Bruno Nyundo, Chacha Werema, Felix A. Shayo, N A Mbwambo

        It is well known that infrastructure development projects can boost the economy and reduce the cost of trade in both developing and developed economies, however, infrastructure projects can also cause biodiversity loss. This book is the result of an important biodiversity survey conducted along an East African railway in Tanzania. The building of the railway, still under construction, has already led to habitat loss, habitat degradation and landscape change which may have affected biodiversity. The book includes recommendations to mitigate the effect of railway construction by protecting biodiversity and ecosystem services which could have major implications across Africa and other regions. The area covered by the survey focuses on the Standard Gauge Railway (SGR) running through the Pugu and Ruvu South Forest Reserves towards Maktupora-Dodoma, plus data on large mammals through to Isaka-Shinyanga. The Pugu forests boast high biodiversity of both flora and fauna, some of which are endemic to the area. There are both plant and animal species that are of major conservation concern so there is urgent need to consolidate information to help formulate suitable conservation measures. The data collected covers plants, invertebrates, amphibians, birds, and mammals for terrestrial and aquatic environments along the SGR. This work is timely as there are many more ongoing SGR construction projects in Tanzania and across Africa, as such construction activities inevitably involve some habitat modification and destruction that may have a negative impact on biodiversity. National and international scientists, decision and policy makers, as well as ecologists and conservation managers involved in large infrastructure projects will find this book invaluable. The book provides baseline information and can be used as a case study for other infrastructure development projects around the world.

        by Zhanhuan Shang, Allan Degen, Devendra Gauchan, Madan Koirala, Muhammad Khalid Rafiq, Awais Iqbal, Binyu Luo, Dawei Zhang, Diwakar Adhikari, Dongmei Li, Furbe Lama, Haonan Guo, Hui Xu, Huma Ali, Jalal Hayat Khan, Jiayi He, Jie Lian, Mei Huang, Monika Ghimire, Narayan Prasad Gaire, Peipei Liu, Qinghui Fang, Ramesh Prasad Sapkota, Ramesh Raj Pant, Rashila Deshar, Ritika K.C, Rui Zhang, Rukhsanda Aziz, Srijana Khanal, Tianyun Qi, Udhab Raj Khadka, Usha Rai, Usman Ali, Wenyin Wang, Xiaoping Jing, Yamuna Ghale, Youyan Liu, Zhen Peng, Zhiqiang Dang

        The years 2021 to 2030 have been designated as "The United Nations Decade on Ecosystem Restoration". Ecological restoration and biodiversity conservation efforts face unprecedented challenges, especially in developing countries and areas, such as the Hindu Kush-Himalayan (HKH) region. This huge HKH region, which includes areas in eight separate countries (Afghanistan, Pakistan, Nepal, India, China, Bangladesh, Myanmar and Bhutan), is a biodiversity hotspot with a vast array of ecosystems, landscapes, peoples and cultures. It is known as one of 'the pulses of the world'. However, the HKH is also the world's largest and poorest mountain region, where landscapes and environments have been severely damaged as a result of climate change and human activities. Coordinating conservation and restoration policies, sharing knowledge and funds, and maintaining livelihoods are major challenges and are in urgent need of improvement. This book details the past and current ecological problems in the HKH region, and the threats and challenges that ecosystems and local people face. It pays special attention to developments of transformative adaptations and presents examples of sustainable conservation and ecological restoration management practices. Three primary questions are addressed: (1) Do the existing conservation strategies of international organizations and government policies really protect ecosystems and solve biodiversity problems? (2) Can these management measures be one-time solutions? and (3) What is the strategic framework and scenario prognosis for the future based on the historical trajectory of ecological conservation and restoration in the region? This book is essential reading for ecologists and conservation biologists involved in large-scale ecological restoration projects, along with practitioners, graduate students, policy makers and international development workers.

        RNAi for Plant Improvement and Protection

        by Bruno Mezzetti, Jeremy Sweet, Lorenzo Burgos

        RNA interference (RNAi) has the potential to make major contributions towards sustainable crop production and protection with minimal environmental impacts compared to other technologies. RNAi is being developed and exploited both within plants (i.e. host-induced gene silencing, HIGS) and/or as topical applications (e.g. spray-induced gene silencing, SIGS) for targeting pest and pathogen genes and for manipulating endogenous gene expression in plants. Chapters by international experts review current knowledge on RNAi, methods for developing RNAi systems in GM plants and applications for crop improvement, crop production and crop protection. Chapters examine both endogenous systems in GM plants and exogenous systems where interfering RNAs are applied to target plants, pests and pathogens. The biosafety of these different systems is examined and methods for risk assessment for food, feed and environmental safety are discussed. Finally, aspects of the regulation of technologies exploiting RNAi and the socio-economic impacts of RNAi technologies are discussed.

        a Central Dogma Perspective and Strategies for Enhancement

        by Showkat Ahmad Ganie, Shabir Hussain Wani

        Gene expression in cells follows a prescribed pathway that conforms to the Central Dogma; where the genetic information stored in DNA is transcribed into RNA and then expressed into proteins, which influences most plant traits. Plant salt tolerance research is directed towards identifying nucleotide variants that could contribute to tolerant phenotypes. This book comprehensively presents the current state of knowledge on plant salt tolerance through meticulous analysis of the processes operating across the Central Dogma. It provides a detailed account of modulation of gene expression through genome editing systems to achieve crop improvement against salt stress. It also provides state-of-the-art information on advances in breeding technologies of genome selection and accelerated de novo domestication for rapidly improving the salt tolerance of plants for global food security. This book: 1.Provides a comprehensive coverage of plant salt tolerance mechanisms. 2.Spotlights various factors functioning along the Central Dogma pathway and their regulation in response to salinity. 3.Examines how these factors function to protect the plants from high salinity. 4.Highlights advances in cutting-edge breeding technologies for improving salt tolerance. The book will be of particular value to students and researchers of plant genetics, molecular biology and physiology and those with an interest in salinity and salt tolerance.
