Book Description
The book compiles case studies regarding the biodiversity research and monitoring program of Andean species and habitats carefully chosen as indicators to assess the short- and long-term effects of a linear disturbance: the PERU LNG pipeline. Set in a scientifically unexplored region of the Andes, Monitoring Biodiversity clearly articulates the Smithsonian-led conceptual framework for the implementation in the field by scientists. It addresses scientific and conservation questions addressed by the research protocols, the experimental design, and data gathering. Moreover, the book covers a gap on how to integrate biodiversity research, monitoring, and conservation into sustainable development projects of national and international interest. The text is presented in both English and Spanish.

Book Description
The consumption of plastic products has increased significantly with the rapid development of the global economy. The total output of virgin plastics has already reached eight billion tons, and the annual global plastic consumption has reached 2.8 billion tons. In parallel with this high consumption rate, a staggering amount of plastic waste is generated annually. As a consequence of incorrect disposal of waste plastics and plastic longevity, this plastic waste is accumulating in the environment at an increasing rate. Moreover, since most plastic waste is corrosion resistant, these plastics do not decompose in the natural environment and can cause serious environmental pollution. In particular, petroleum-based synthetic polymers, including polyethylene, polyvinyl chloride, polystyrene, polypropylene, polyethylene terephthalate, and polyurethanes need hundreds of years to completely degrade in the natural environment. Moreover, although some aliphatic polyesters, such as polybutylene succinate, polycaprolactone, and polylactic acid are considered biodegradable, degradation of these plastics occurs only under specific microorganism activity and under specific conditions. Sometimes the apparent degradation is initiated by hydrolytic activity and not microorganism or enzymatic activity. Large-scale synthesis and application of plastics only began after 1950. Hence, the time span of plastic exposure in the environment has been too short for the adaptive evolution of natural microorganisms. Indeed, natural microorganisms showing high specificity for plastics and a high degradation efficiency are extremely scarce. Because of the inability of most natural microorganisms to recognize and degrade plastics, enzymes that can specifically degrade plastics are also scarce. Many of the enzymes which are known have either an unclear mechanism of the action on the polymer, a poor affinity for their substrates, a low efficiency, or enzyme production yield is currently low. To address these problems, new biotechnology strategies need to be implemented. In particular, new microorganisms and their enzymes need to be identified, and pathways for plastic degradation and molecular modification need to be clarified to enhance the activity and stability of the degrading enzymes. The current Research Topic aims to cover the recent and novel research trends in the development of plastics biodegradation (including petroleum-based plastics and bio-based plastics) under soil, composted, microbial and enzymatic conditions. The recycling technology of degraded products is also of interest.

Book Description
Organic waste composting is another excellent example to demonstrate the power and the benefits of nexus thinking. Even though organic waste composting itself is not a new topic, those who want to start a new project or align an ongoing project with nexus thinking, find it difficult to gather the necessary information. With nine case studies from four continents, this book aims to fill above gap in literature. While current literature on composting is often found to be limited to either soil/agriculture sector or waste management sector, this book presents a combined point of view. This open access book starts with an introductory chapter that describes the need to bring the waste management aspects and soil nutrient management aspects of compost production into one integrated theme. The relevance of nexus thinking and the Sustainable Development Goals (SDGs) are also presented in this introduction. The first three chapters after the introduction covers composting from the solid waste management and its policy aspects, taking examples from three developing countries. The next three examples are mostly about the benefits composting can provide to the soil and agriculture. These examples are also from three developing countries, but with a mixture of urban as well as rural settings. Last three chapters present more insight into the latest developments taking examples from Europe, as well as new methods adapted from the traditional styles from Africa.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.
