This book provides a multi-lateral forum for cooperation, information exchange, and dialogue among the environmental, development, foreign and security policy communities within the Mediterranean Region and thus may provide a precedent for further cooperation and partnership, including other more advanced conferences and publications, on assessing the condition of the entire region and the subsequent impacts and linkages to environmental security.

Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

In recent decades, the various strands of the food movement have made enormous strides in calling attention the many shortcomings and injustices of our food and agricultural system. Farmers, activists, scholars, and everyday citizens have also worked creatively to rebuild local food economies, advocate for food justice, and promote more sustainable, agroecological farming practices. However, the movement for fairer, healthier, and more autonomous food is continually blocked by one obstacle: land access. As long as land remains unaffordable and inaccessible to most people, we cannot truly transform the food system. The term land-grabbing is most commonly used to refer to the large-scale acquisition of agricultural land in Asian, African, or Latin American countries by foreign investors. However, land has and continues to be “grabbed” in North America, as well, through discrimination, real estate speculation, gentrification, financialization, extractive energy production, and tourism. This edited volume, with chapters from a wide range of activists and scholars, explores the history of land theft, dispossession, and consolidation in the United States. It also looks at alternative ways forward toward democratized, land justice, based on redistributive policies and cooperative ownership models. With prefaces from leaders in the food justice and family farming movements, the book opens with a look at the legacies of white-settler colonialism in the southwestern United States. From there, it moves into a collectively-authored section on Black Agrarianism, which details the long history of land dispossession among Black farmers in the southeastern US, as well as the creative acts of resistance they have used to acquire land and collectively farm it. The next section, on gender, explores structural and cultural discrimination against women landowners in the Midwest and also role of “womanism” in land-based struggles. Next, a section on the cross-border implications of land enclosures and consolidations includes a consideration of what land justice could mean for farm workers in the US, followed by an essay on the challenges facing young and aspiring farmers. Finally, the book explores the urban dimensions of land justice and their implications for locally-autonomous food systems, and lessons from previous struggles for democratized land access. Ultimately, the book makes the case that to move forward to a more equitable, just, sustainable, and sovereign agriculture system, the various strands of the food movement must come together for land justice.

In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.
