Book Description
Nitrogen Assessment: Pakistan as a Case-Study provides a detailed overview of issues and challenges related to nitrogen use and overuse, thus serving as a reference for researchers in Pakistan and providing important insights for other geographic regions. Excess and inefficient nitrogen use in crops and livestock sectors is polluting our rivers, seas, atmosphere, and ecosystems, contributing to climate change, hampering biodiversity, and contributing to stratospheric ozone depletion. This book covers the importance of nitrogen in relation to food security, human health, and economic stability in South Asia. It also discusses nitrogen status, sources, sinks, and drivers of nitrogen use in Pakistan, focusing on current nitrogen measures and policies.Nitrogen pollution is one of the biggest challenges of 21st Century, and the international scientific community is beginning to recognize the significance of nitrogen pollution and to explore how to combat it. The editors' institution, University of Agriculture, Faisalabad, partners with South Asia Nitrogen Hub, which includes about 30 organizations from South Asia and UK working on nitrogen assessment, budgeting, awareness, and policy guidance, as well as possible measures to reduce nitrogen pollution.Nitrogen Assessment: Pakistan as a Case-Study provides an important guide to this work and is written in a way that is accessible to an audience with a wide range of experience from advanced students to seasoned researchers. - Presents an excellent compilation of research-based findings in the first comprehensive assessment of nitrogen use in Pakistan - Offers a detailed and comprehensive compilation of data and content from a variety of sources - Analyzes important translational insights for other geographic regions seeking to maximize nutrient use efficiency

Book Description
Anthropogenic nitrogen (N) emissions drastically altered the global N cycle over the 20th century. Activities associated with N emissions, such as intensive agriculture and the burning of fossil fuels, greatly increased human well-being. At the same time, the numerous environmental impacts of elevated N availability became apparent. In Europe, N deposition decreased by 36% between 1990 and 2018 due to clean air policies and economic transformation but is in many regions still at a high level. Europe's forests are an important receptor for N emissions, due to their large land use share and e...

Book Description
Providing a wealth of in-depth knowledge of forest ecosystems, this new volume explores a collection of important topics on forest community dynamics. It looks at the diversity of forest ecosystems and explores such aspects as forest products in enhancing local livelihoods and community participation, forage production, forest conservation and sustainable management, regeneration patterns, seed handling, and more. Chapters in Diversity and Dynamics in Forest Ecosystems present new research on forest products, livelihood generation mechanisms of forest-dependent communities, utilization patterns of untapped resources from forests, and the structure of different ecosystems from the tropical to the temperate landscape. This book also features different drivers of community dynamics, such as the role of seed handling in forests, the influence of altitudinal variations, and protected and community-conserved forests on the forest diversity. Chapters also consider the role of non-timber forest products and their significance in livelihood diversification for tribal communities and forage crop genetic resources, and forest resource extraction by forest fringe dwellers. Also explored are aspects of soil organic carbon in agroforestry systems and integrated approaches of sustainable agroforestry development in diverse forest ecosystems. This edition also examines the vegetation structure and regeneration aspects of timberline zone, including diversity of herbaceous flora along the altitudinal gradient. The abundance of in-depth knowledge of the diversity and dynamics of forest ecosystems in this volume will be valuable in conservation and management of forests, which play an important role in the world environment. Forests are presently facing multiple disturbances, and this volume will help forestry professionals and others formulate further strategies to mitigate global climate change and other challenges.

Book Description
The majority of carbon stored in the soils of the world is stored in forests. The refractory nature of some portions of forest soil organic matter also provides the slow, gradual release of organic nitrogen and phosphorus to sustain long term forest productivity. Contemporary and future disturbances, such as climatic warming, deforestation, short rotation sylviculture, the invasion of exotic species, and fire, all place strains on the integrity of this homeostatic system of C, N, and P cycling. On the other hand, the CO2 fertilization effect may partially offset losses of soil organic matter, but many have questioned the ability of N and P stocks to sustain the CO2 fertilization effect. Despite many advances in the understanding of C, N, and P cycling in forest soils, many questions remain. For example, no complete inventory of the myriad structural formulae of soil organic N and P has ever been made. The factors that cause the resistance of soil organic matter to mineralization are still hotly debated. Is it possible to “engineer” forest soil organic matter so that it sequesters even more C? The role of microbial species diversity in forest C, N, and P cycling is poorly understood. The difficulty in measuring the contribution of roots to soil organic C, N, and P makes its contribution uncertain. Finally, global differences in climate, soils, and species make the extrapolation of any one important study difficult to extrapolate to forest soils worldwide.
