Integrated global assessment of the natural forest carbon potential
Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land use and climate have considerably reduced the scale of this system 1 . Remote-sensing estimates to quantify carbon losses from global forests 2–5 are characterized by considerable uncertainty and we lack a comprehensive ground-sourced evaluation to benchmark these estimates. Here we combine several ground-sourced 6 and satellite-derived approaches 2,7,8 to evaluate the scale of the global forest carbon potential outside agricultural and urban lands. Despite regional variation, the predictions demonstrated remarkable consistency at a global scale, with only a 12% difference between the ground-sourced and satellite-derived estimates. At present, global forest carbon storage is markedly under the natural potential, with a total deficit of 226 Gt (model range = 151–363 Gt) in areas with low human footprint. Most (61%, 139 Gt C) of this potential is in areas with existing forests, in which ecosystem protection can allow forests to recover to maturity. The remaining 39% (87 Gt C) of potential lies in regions in which forests have been removed or fragmented. Although forests cannot be a substitute for emissions reductions, our results support the idea 2,3,9 that the conservation, restoration and sustainable management of diverse forests offer valuable contributions to meeting global climate and biodiversity targets.

Natural resources
\"Natural resources are anything from nature that people can use. From fossil fuels deep underground used for power to trees used for lumber, natural resources are precious and sometimes nonrenewable. Readers learn both how natural resources are accessed as well as the importance of conserving them in two ways: traditional chapter text on each topic and a colorful flowchart to help them add a layer of understanding to their reading. Including topics supportive of the Earth science curriculum, this book covers renewable energy, mineral mining, water, and much more, as well as full-color photographs which have a strong text correlation.\"--Amazon.

This Land, This Nation
This 2007 book combines political with environmental history to present conservation policy as a critical arm of New Deal reform, one that embodied the promises and limits of midcentury American liberalism. It interprets the natural resource programs of the 1930s and 1940s as a set of federal strategies aimed at rehabilitating the economies of agricultural areas. The New Dealers believed that the country as a whole would remain mired in depression as long as its farmers remained poorer than its urban residents, and these politicians and policymakers set out to rebuild rural life and raise rural incomes with measures tied directly to conservation objectives - land retirement, soil restoration, flood control, and affordable electricity for homes and industries. In building new constituencies for the environmental initiatives, resource administrators and their liberal allies established the political justification for an enlarged federal government and created the institutions that shaped the contemporary rural landscape.

20 fun facts about Earth's resources
Geothermal heat, made by the disintegration of the radioactive atoms in Earth's core, is not a subject young readers often get to learn about. Heavy metals and solar energy, two topics that are constantly appearing in technology news today, are typically left for more advanced readers to discover and understand. By using accessible yet exciting language and bold, colorful photography and art, this book lets young readers explore a plethora of fascinating yet digestible facts about what our planet naturally provides and how we harness it.

Social Networks and Natural Resource Management
Social Network Analysis (SNA), a quantitative approach to the study of social relations, has recently emerged as a key tool for understanding the governance of natural resources. Bringing together contributions from a range of researchers in the field, this is the first book to fully explore the potential applications of SNA in the context of natural resource management. Topics covered include the role of SNA in stakeholder selection; improving fisheries management and conservation; the effect of social network ties on public satisfaction and agrarian communication networks. Numerous case studies link SNA concepts to the theories underlying natural resource governance, such as social learning, adaptive co-management and social movements theory. Reflecting on the challenges and opportunities associated with this evolving field, this is an ideal resource for students and researchers involved in many areas of natural resource management, environmental biology, sustainability science and sociology.

Capacity shortfalls hinder the performance of marine protected areas globally
Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes remain unknown. We developed a global database of management and fish population data (433 and 218 MPAs, respectively) to assess: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects. Here we report that many MPAs failed to meet thresholds for effective and equitable management processes, with widespread shortfalls in staff and financial resources. Although 71% of MPAs positively influenced fish populations, these conservation impacts were highly variable. Staff and budget capacity were the strongest predictors of conservation impact: MPAs with adequate staff capacity had ecological effects 2.9 times greater than MPAs with inadequate capacity. Thus, continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes.
Although 71% of marine protected areas are benefiting fish populations, their effects are highly variable, with staff capacity proving to be the most important explanatory variable.
Staff needed to safeguard seas
Marine protected areas are proliferating quickly in the hope of safeguarding marine resources. Here David Gill and colleagues show that inadequate staffing capacity is compromising the efficacy of marine protected areas globally. They analyse fish biomass and management data for marine protected areas around the world and find that, although 71% of these protected areas are benefiting fish populations, the effects are highly variable. Staff capacity was identified as the most important explanatory variable, accounting for around 19% of the variation in the benefits of marine protection. They suggest that continued expansion of marine protected areas around the globe without adequate investment in human and financial capacity could limit marine conservation outcomes.
