Abstract Forests are critical for stabilizing our climate, but costs of mitigation over space, time, and stakeholder group remain uncertain. Using the Global Timber Model, we project potential four abatement activities across 16 regions carbon price scenarios $5–$100/tCO 2 . We 0.6–6.0 GtCO yr −1 in global by 2055 at 2–393 billion USD , with avoided tropical deforestation comprising 30–54% total mitigation. Higher prices incentivize larger proportions via rotation forest management temperate...
The protection of forests is crucial to providing important ecosystem services, such as supplying clean air and water, safeguarding critical habitats for biodiversity, reducing global greenhouse gas emissions. Despite this importance, forest loss has steadily increased in recent decades. Protected Areas (PAs) currently account almost 15% Earth’s terrestrial surface protect 5% tree cover were developed a principal approach limit the impact anthropogenic activities on natural, intact...
Many countries have taken on ambitious but potentially costly renewable energy development goals to combat climate change. The government of Guatemala has introduced a plan increase generation capacity, while an estimated 76% Guatemalans are poor. In this paper, we evaluate the trade-offs between alleviating poverty and achieving in Guatemala. We present framework that combines electricity cost model with household expenditure survey assess effects national goal could through added...
In recent years several U.S. federal policies have been adopted to support forest-based climate mitigation actions. This study focuses on current funds allocated forest for change activities assess how much they could deliver in terms of net sequestration under a best-case (optimized) scenario where the cheapest abatement options are implemented first and if these line achieve domestic targets 2030 2050. Multiple investments pathways tested two different assumptions CO2 fertilization provide...
Abstract Groundwater pumping contributes significantly to land subsidence, which generates economic costs as changes in the frequency of flooding affect property values. We evaluate these by estimating marginal damages from pumping, define corrective policy incentive address subsidence externalities. In an application southern Chesapeake Bay region Virginia, we find that due groundwater is greatest inland rural areas, but are coastal urban areas. Our results suggest cost‐minimizing spatially...
The interconnectedness of food, energy, and water systems – commonly referred as the FEW nexus - calls for integrated study these to improve resiliency natural resources adapt our changing world. In this article, we explore state research in Guatemala highlight progress while also pointing out future needs. A systematic literature review was conducted identify peer-reviewed articles grey published on topic from January 2000 May 2020. Articles were reviewed classified Guatemalan location,...
The land sector is anticipated to play an important role in achieving U.S. GHG emissions targets by reducing and increasing sequestration from the atmosphere. This study assesses how much different levels of investment could stimulate land-based mitigation activities By applying a dynamic economic model use sectors, with representation 26 forestry agricultural strategies across 11 regions, shows that annual investments $2.4 billion deliver abatement around 80 MtCO
Abstract To model international trade of forest products we use a gravity trade. In modeling trade, estimate the impact importer gross domestic product (GDP), exporter GDP, and distance between trading partners using Poisson pseudo-maximum likelihood (PPML). When estimating log-linearized (ordinary least squares [OLS]), two issues arise. First, potential bias associated with truncation all zero-trade observations due to nonexistence natural log zero. Second, heteroscedasticity can results...
Abstract The achievement of several sustainable development goals and the Paris Climate Agreement depends on rapid progress towards food land systems in all countries. We have built a flexible, collaborative modeling framework to foster national pathways by local research teams their integration up global scale. Local researchers independently customize models explore mid-century use system transformation collaboration with stakeholders. An online platform connects models, iteratively...
The life cycle greenhouse gas (GHG) emissions of biofuels depend on uncertain estimates induced land use change (ILUC) and subsequent from carbon stock changes. Demand for oilseed-based is associated with particularly complex market supply chain dynamics, which must be considered. Using the global partial equilibrium model GLOBIOM, this study explores uncertainty in market-mediated impacts ILUC-related increasing demand soybean biodiesel United States period 2020-2050. A one-at-a-time (OAT)...
As the demand for forest products and carbon storage in standing timbers increases, intensive planting of resources is expected to increase. With increased use plantation practices, it important understand influence that plot characteristics have on likelihood where these practices are occurring. Depending goals a policy or program, increasing could be desirable outcome something avoid. This study estimates spatially explicit logistical regression function assess plots will planted based...
Climate change, growing populations, and increasing wealth are demand for food, energy, water. Additionally, water stress is expected to increase in the future areas with high rates of seasonality precipitation, due increased variability precipitation. One approach limiting impact climate change on food system productions through intensive extensive expansion irrigated agriculture. This study develops a hydro-economic model assess agriculture production possibilities role irrigation Pacific...
The Forestry and Agriculture Sector Optimization Model with Greenhouse Gases (FASOMGHG) has historically relied on regional average costs of land conversion to simulate use change across cropland, pasture, rangeland, forestry. This assumption limits the accuracy estimates by not recognizing spatial heterogeneity in quality costs. Using data from Nielsen et al. (2014), we obtained afforestation cost per county, then estimated nonparametric marginal functions for converting These were...
With the rapid increase in number of mega-infrastructure projects underway across East Africa, how social, economic, political and environmental repercussions these intersect with ongoing conflict dynamics is a poorly understood topic. Although recent interest large-scale land acquisitions has led to detailed investigations into specific trends, there not yet been broad, systematic review infrastructure developments Africa interact previous, potential their areas operation. The objective...
A family of plane curves is developed which can diffract incident parallel rays to a point focus. These curves, termed diffractoidal are rotated around an axis produce surfaces revolution correspondingly diffractoids, whose imaging properties for sources at infinity studied by ray tracing in few examples. The paraboloid emerges as limiting case the diffractoid. comparison made between stigmatic focusing diffractoid and toroidal grating.
Limited information is available regarding chemical water quality at the tap in Guatemala City, preventing individuals, utilities, and public health authorities from making data-driven decisions related to quality. To address this need, 113 participants among households served by a range of providers across City metropolitan area were recruited as participatory scientists collect first-draw flushed samples their residence. Samples transported U.S. analyzed for 20 metals 25 per-...
Abstract Meeting ambitious climate targets will require deploying the full suite of mitigation options, including those that indirectly reduce greenhouse-gas (GHG) emissions. Healthy diets have sustainability co-benefits by directly reducing livestock emissions as well land use Increased crop productivity could avoid cropland area. However, there is disagreement on proposed healthy U.S. and a lack clarity how long-term benefits may change in response to shifts sector. Here, we explore GHG...
