Ciencias de la Tierra, Facultad de Ciencias, Universidad de Zaragoza, c/ Pedro Cerbuna 12, E-50009 Zaragoza, Spain [email protected], [email protected], [email protected], [email protected] *Corresponding author Received: 27/06/2011 / Accepted: 29/02/2012 Abstract Among the conspicuous extensional structures that accommodate the onshore deformation of the Valencia Trough at the central- eastern Iberian Chain, a number of large faults show evidence of activity during Pleistocene times. At the eastern boundary of the Jiloca graben, the Concud fault has moved since mid Pliocene times at an average rate of 0.07-0.08 mm/y, while rates from 0.08 to 0.33 mm/y have been calculated using distinct stratigraphic markers of Middle to Late Pleistocene age. A total of nine paleoseisms associated to this fault have been identified between 74.5 and 15 ka BP, with interseismic periods ranging from 4 to 11 ka, estimated coseismic displacements from 0.6 to 2.7 m, and potential magnitudes close to 6.8. The other master faults of the Jiloca graben (Ca- lamocha and Sierra Palomera faults) have also evidence of Pliocene to Late Pleistocene displacement, with average slip rates of 0.06 and 0.11-0.15 mm/y, respectively. -

Conclusions Glossary Bibliography Biographical Sketch Summary UNESCO – EOLSS Africa is particularly vulnerable to desertification. Two thirds of the continent consists of desert or drylands.SAMPLE The obvious causes of desertificatiCHAPTERSon and deforestation consist of major ecosystem changes, such as land conversion for various purposes, over- dependence on natural resources and several forms of unsustainable land use. However, the issue of desertification is inseparable from social problems such as poverty and land tenure issues. Politics, war and national disasters affect the movements of people and thus impact on the land. International trade policies as well play a part in land management and/or exploitation. -

Christensen, Supervisor ___________________________ Alexander Pfaff ___________________________ Dean L. Urban ___________________________ Randall A. Kramer An abstract of a dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the University Program in Ecology in the Graduate School of Duke University 2008 Copyright by Dalia Amor Conde Ovando 2008 Abstract The construction of roads, either as an economic tool or as necessity for the implementation of other infrastructure projects is increasing in the tropical forest worldwide. However, roads are one of the main deforestation drivers in the tropics. In this study we analyzed the impact of road investments on both deforestation and jaguar habitat loss, in the Mayan Forest. As well we used these results to forecast the impact of two road investments planned in the region. Our results show that roads are the single deforestation driver in low developed areas, whether many other drivers play and important role in high developed areas. In the short term, the impact of a road in a low developed area is lower than in a road in a high developed area, which could be the result of the lag effect between road construction and forest colonization. -

U.S. Natural Climate Solutions Accelerator Finalist: Forests of the Future: Replanting Burn Scars for Carbon Sequestration and Ecosystem Services
U.S. Natural Climate Solutions Accelerator Finalist: Forests of the Future: Replanting Burn Scars for Carbon Sequestration and Ecosystem Services. Collaboration between Coalitions and Collaboratives, Inc. (COCO) and RenewWest. Forests of the Future initiative aims to reforest post-fire landscapes that are not naturally recovering, and to develop an investable carbon-focused market mechanism and a “carbon reforestation fund” model to bring additional capital for reforestation and carbon sequestration. By quantifying tree growth into a carbon offset equivalent, an additional source of value is created for forest owners, which can be brought for sale to carbon offset buyers in the Western Climate Initiative (WCI) compliance marketplace in California and voluntary carbon markets. Conservation co-benefits include habitat restoration promoting biodiversity, improving soil health and preventing erosion, maintaining watershed health through improved stream clarity and temperature. Economic co-benefits include improving value of degraded lands, re-establishing working lands to sustainable Forest Stewardship Council (FSC) certified wood production, and creating a source of employment for rural communities engaged in a deforestation-free timber supply chain. Investors seeking low-correlated, attractive risk-adjusted prospects, can consider a fund of combined projects, which aims to provide predictable long-term market-rate returns and quantifiable environmental and social impacts. How it works: The pilot project will be implemented in Modoc County, California on an 11,516- acre parcel of land owned by Collins Timber, which is not naturally recovering after it burned in the 2012 Barry Point Fire. Following the 30-year project period, Collins Timber will retain the ability to use the lands for sustainable, mixed-age selective-harvest forestry, certified by FSC. -

Desertification and Agriculture
BRIEFING Desertification and agriculture SUMMARY Desertification is a land degradation process that occurs in drylands. It affects the land's capacity to supply ecosystem services, such as producing food or hosting biodiversity, to mention the most well-known ones. Its drivers are related to both human activity and the climate, and depend on the specific context. More than 1 billion people in some 100 countries face some level of risk related to the effects of desertification. Climate change can further increase the risk of desertification for those regions of the world that may change into drylands for climatic reasons. Desertification is reversible, but that requires proper indicators to send out alerts about the potential risk of desertification while there is still time and scope for remedial action. However, issues related to the availability and comparability of data across various regions of the world pose big challenges when it comes to measuring and monitoring desertification processes. The United Nations Convention to Combat Desertification and the UN sustainable development goals provide a global framework for assessing desertification. The 2018 World Atlas of Desertification introduced the concept of 'convergence of evidence' to identify areas where multiple pressures cause land change processes relevant to land degradation, of which desertification is a striking example. Desertification involves many environmental and socio-economic aspects. It has many causes and triggers many consequences. A major cause is unsustainable agriculture, a major consequence is the threat to food production. To fully comprehend this two-way relationship requires to understand how agriculture affects land quality, what risks land degradation poses for agricultural production and to what extent a change in agricultural practices can reverse the trend. -

Ramping up Reforestation in the United States: a Guide for Policymakers March 2021 Cover Photo: CDC Photography / American Forests
Ramping up Reforestation in the United States: A Guide for Policymakers March 2021 Cover photo: CDC Photography / American Forests Executive Summary Ramping Up Reforestation in the United States: A Guide for Policymakers is designed to support the development of reforestation policies and programs. The guide highlights key findings on the state of America’s tree nursery infrastructure and provides a range of strategies for encouraging and enabling nurseries to scale up seedling production. The guide builds on a nationwide reforestation assessment (Fargione et al., 2021) and follow-on assessments (Ramping Up Reforestation in the United States: Regional Summaries companion guide) of seven regions in the contiguous United States (Figure 1). Nursery professionals throughout the country informed our key findings and strategies through a set of structured interviews and a survey. Across the contiguous U.S., there are over 133 million acres of reforestation opportunity on lands that have historically been forested (Cook-Patton et al., 2020). This massive reforestation opportunity equals around 68 billion trees. The majority of opportunities occur on pastureland, including those with poor soils in the Eastern U.S. Additionally, substantial reforestation opportunities in the Western U.S. are driven by large, severe wildfires. Growing awareness of this potential has led governments and organizations to ramp up reforestation to meet ambitious climate and biodiversity goals. Yet, there are many questions about the ability of nurseries to meet the resulting increase in demand for tree seedlings. These include a lack of seed, workforce constraints, and insufficient nursery infrastructure. To meet half of the total reforestation opportunity by 2040 (i.e., 66 million acres) would require America’s nurseries to produce an additional 1.8 billion seedlings each year. -

With this method, you do not have to reset the system to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can generate highly reliable measurement data. Advantages: 1. No count error occurs even if you move the slider or spindle extremely rapidly. 2. You do not have to reset the system to zero when turning on the system after turning it off*1.
