October 2024Biodiversity 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.

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.

June 2024Sustainable Ecological Restoration and Conservation in the Hindu-Kush Himalayan Region
A Comprehensive Review
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.

Children's & YAFebruary 2014Red Line
by Samar Mahfouz BarrajIllustrated By: Mona Yakzan and Mira El-Myr
Mazen, a young boy, is one day surprised by their neighbor Bassam shouting with anger in the street “My parking spot is a red line!” Does this mean he plans to paint the street red, asks Mazen to his mother? The mother explains to Mazen that what Bassam means is simply that no one is to park in his place. The notion is still vague to Mazen: Why red? Does it have anything to do with red traffic lights? The mother tries again “When something is a red line, it means that it is off limits to others”. In this illustrated album, Samar Barraj boldly addresses the delicate issue of child sexual abuse. Acknowledging the complexity of the boundary it tackles, the book determines it through examples the mother and child raise in their conversation. Mazen’s spontaneous remarks and comments point out the difficulty of defining this red line, and make of the book a realistic example of such a conversation. The illustrations develop the notion further, by representing situations in which the red line might be crossed – one may be on his bicycle, at his computer, or approached by a respectable-looking old man in the street. The body parts are not named, but are represented in a naïve drawing Mazen made, though the text insists on the importance of preserving the body as a whole. The colorful images and constant presence of the mother and parents make of the book a reassuring experience despite the gravity of the topic.

Fertilizers & manuresFebruary 2006Soil Biodiversity in Amazonian and Other Brazilian Ecosystems
by Edited by Fattima M S Moreira, Jose O Siqueira, Lijbert Brussaard
The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.

Monitoring, Assessment and Conservation
by Edited by Abid A Ansari, Sarvajeet Singh Gill
Plants are important components to the ecosystem. They are the base of the food chain and play a significant role in energy flow and biogeochemical cycling of nutrients between terrestrial and aquatic ecosystems. They must constantly fight against the environmental modifications, however, that threaten to cause global species extinction and habitat destruction. A new multidisciplinary science has evolved to deal with the crises confronting biological diversity. It has two goals: first, to investigate human impacts on biological diversity and second, to develop practical approaches to prevent extinction of species. This book is a practical update on our knowledge on monitoring, assessment and conservation of plant biodiversity in aquatic and terrestrial ecosystems and related fields. It includes a general overview of plant biodiversity, investigates a wealth of factors affecting and hindering plant biodiversity before exploring in depth methods of monitoring, assessing and conserving our plant species. Globally relevant, this book is a valuable resource for all researchers, professionals and students of botany and plant biodiversity studies.

Forestry & silviculture: practice & techniquesOctober 2007Biodiversity Loss and Conservation in Fragmented Forest Landscapes
The Forests of Montane Mexico and Temperate South America
by Adrian C Newton
Increasing concern surrounding the loss of natural forests and the decline in biodiversity has lead to a rise in research and policy initiatives in recent years. However, interest has focused primarily on lowland tropical rainforests. Tropical montane and temperate rainforests, which face similar pressures from human activities and play major roles in the livelihood of rural communities, are often ignored. Biodiversity Loss and Conservation in Fragmented Forest Landscapes is the product of over 10 years of intensive field research into the changing montane and temperate rainforests of Mexico and South America. By concentrating on these largely overlooked environments, the studies reported allow for comparative analysis across areas and help identify how human disturbance has impacted the biodiversity of all forest types. Chapters incorporate features of landscape ecology, floristic biodiversity, conservation and policy and vary from in-depth investigations of a single study area to integrated examinations across regions.

January 2018Biodiversity, Revised Edition
Conserving Endangered Species
by Anne Maczulak, Ph.D.
Students with a basic understanding of the environment and concern for its future know the importance of preserving biological diversity. Biodiversity is the variety of living things on Earth or in a specific area. This definition seems simple enough to understand, yet the concept of biodiversity has deeper meanings that challenge even trained environmental scientists. A region that has a wide variety of species in robust populations is said to possess biodiversity. But not every place on Earth bursts with diverse life. Biodiversity concentrates in certain areas, while other parts of the globe possess a somewhat lesser variety and number of species. Biodiversity, Revised Edition takes a look at how habitats are destroyed, the devastating effect this has on biodiversity, and the ways in which scientists restore ecosystems and habits. This updated, full-color book also examines the ethical questions that arise when trying to rescue threatened species in the face of dire human conditions. Chapters include: Endangered Species Measuring Species and Extinction Protecting Native from Invasive Species Urban Development Nature Reserves Species Protection Methods for Measuring Diversity.

September 2025Habitat
The Fundamental Unit for Understanding and Conserving Nature
by Roger L H Dennis, Simone Fattorini
Habitat is the fundamental unit for understanding species ecology and preserving biodiversity; it has always had a variety of meanings often not explicitly defined. This important book focuses on the two main uses of the term and their importance for nature conservation. The first, traditional usage (TH), is that of terrestrial, aquatic or aerial spatial units which can be denoted by the species they host, with associated trophic relationships and interdependencies. The second, termed resource-based habitat (RBH), focuses on any one species' habitat. These RBHs are rarely limited to one space but are defined by the intersection of appropriate resources and suitable conditions. Since the ability of individuals to exploit resources is influenced by their own unique combination of traits, the RBH is spatially and temporally variable. The book explores how communities are structured, how species and individuals interact (niches, guilds, food webs, etc.), and how biodiversity changes over space and time. Typically, a location distinguished by specific attributes (TH; a meadow, a wood, a field, etc.) has few common species, but many rare ones and the book explores this long challenging conundrum. The TH usage has immense importance and implications for maintaining wildlife. Because of the variety of the ecological characteristics of different species, the study of them in distinctive spatial units (a lake, a moor, the seashore, the lower atmosphere, etc.) requires special methods in each case to determine their conservation status. The RBH is critical for understanding the factors necessary for the maintenance of 'focal' species, regarded as key or rare elements of ecosystems. The book explores the different ways in which such species are maintained: i.e., their traits, defining their ecological and behavioural uniqueness, morphology, physiology, biochemistry, and the resources-and conditions-on which they depend. It also examines how, as specialists or generalists, species are placed in the trophic hierarchy, how they fit into their communities and influence the evolution (or demise) of other species. Ultimately, the book investigates how best to conserve biodiversity.
