Book Description
This book develops and presents a conceptual model for sustainable-groundwater irrigated agriculture. The model is based on the general principles of the economic theories of cost-benefit relations and behavioral models of resource use. The study has evaluated the advances in tubewell farming and the aquifer potential in arid Balochistan over a period of three decades. It has analyzed the booms and busts of the farming over time taking into consideration the local aquifer limitations and the socio-political considerations and policy framework. Three data sets – farmers, expert officials and satellite images - have been used to aid validation. By observing the most vital parameters, the study has concluded that the local aquifer has been falling at a rate directly proportional to the growth rate of irrigated farming, suggesting the current development process is unsustainable. For instance, the research finds that tubewell bores have reached down to depths where the term “aquifer mining” applies; as a result, irrigation costs have become too high to allow farming to be economically viable. In addition, desertification is steadily encroaching and the cropping pattern being changed from high-value horticulture to subsistence cropping. The study has also set parameters for assessing the willingness of farmers to accept modern, sustainable strategies and interventions.

Book Description
The volume Middle East and North Africa: Climate, Culture and Conflicts focuses on the intricate interrelationships between nature, culture and society in this ecologically, historically and politically fragile region. As such, it debates ideas of eco-theology from Muslim and Jewish perspectives, followed by mythological interpretations and geo-archeological resp. historical analyses of the interrelationships and impacts of climate and other environmental factors on the development of ancient civilizations and cultures. The section “Present” addresses current conflict scenarios as a result of climate change, i.e. water scarcity, droughts, desertification and similar factors. The final section is concerned with potentials of international cooperation in pursuit of developing and ensuring sustainable energy resources and moves across different scales of environmental and religious education, from awareness raising to perspectives of best practice examples. Contributors are Katajun Amirpur, Helmut Brückner, Eckart Ehlers, Max Engel, Kerstin Fritzsche, Ursula Kowanda-Yassin, Tobias von Lossow, Ephraim Meir, Rosel Pientka-Hinz, Matthias Schmidt, and Franz Trieb.

Book Description
The human-environment relationship - intimately intertwined and often contentious - is one of the most pressing concerns of the 21st century. Explored through an array of critical approaches, this book brings together case studies from across the globe to present significant cutting-edge research into political ecologies as they relate to multi-form contestations over environments, resources and livelihoods. Covering a range of issues, such as popular discourses of environmental 'collapse', climate change, water resource struggles, displacement, agro-food landscapes and mapping technologies, this edited volume works to provide a broad and critical understanding of the narratives and policies more subtly shaping and being shaped by underlying environmental conflicts. By exploring the power-laden processes by which environmental knowledge is generated, framed, communicated and interpreted, Contentious Geographies works to reveal how environmental conflicts can be (re)considered and thus (re)opened to enhance efforts to negotiate more sustainable environments and livelihoods.

Book Description
This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.

Book Description
Agriculture plays a pivotal role in the economy and development of Pakistan providing food to consumers, raw materials to industries, and a market for industrial goods. Unfortunately, agricultural production is stagnant due to several barriers including a fixed cropping pattern, reliance on a few major crops, a narrow genetic pool, poor seed quality, and a changing climate. In addition, the high cost of production, weak phytosanitary compliance mechanisms, and a lack of cold chain facilities makes Pakistan agriculturally uncompetitive in export markets. Despite all these issues, agriculture is the primary industry in Pakistan and small farmers continue to dominate the business. Small farmers grow crops for subsistence under a fixed cropping pattern and a holistic approach is required to develop agriculture to improve the livelihoods of the rural populace. This book presents an exhaustive look at agriculture in Pakistan. Chapters provide critical analyses of present trends, inadequacies in agriculture, strategic planning, improvement programs and policies while keeping in view the natural resources, plant- and animal-related agricultural production technologies, input supplies, population planning, migration and poverty, and balanced policies on finance, credit, marketing, and trade.

Book Description
The proceedings from The Water and Society Conference 2015 aim to encourage trans-disciplinary communication on issues related to the nature of water, and its use and exploitation by society. The papers within this book demonstrate the need to bridge the gap between the broad spectrum of socio-political sciences and humanistic disciplines and specialists in physical sciences, biology, environmental sciences and health. The Water and Society conference series which began 2011 comprise of issues such as the need for clean and inexpensive water by an increasing global population, and the growing demands of Agriculture and Industry. The book deals with the interaction between water and energy systems, as well as the more technical aspects of water resources management and quality, in the aim to help the policy makers put forward policies and legislation that will lead to improved solutions for all. Topics covered include: Water as a human right; Water quality; Water resources contamination; Water sanitation and health; Water and disaster management; Future water demands; Irrigation and desertification.

Book Description
This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is important in agriculture as it provides a reliable fallback when rainfeeding fails. It is therefore instrumental in managing risk and optimizing food production. However accessing groundwater has become habit and turned to dependency. Resources limits on many key aquifers have been exceeded and competition for groundwater has become intense. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management.
