Increasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon a high priority. Biofuels are potential source, but whether biofuels offer savings depends on how they produced. Converting rainforests, peatlands, savannas, or grasslands produce food crop-based in Brazil, Southeast Asia, the United States creates "biofuel debt" by releasing 17 420 times more CO2 than annual greenhouse gas (GHG) reductions that these would provide...
Background As the global human population grows and its consumption patterns change, additional land will be needed for living space agricultural production. A critical question facing society is how to meet growing demands space, food, fuel, other materials while sustaining ecosystem services biodiversity [1]. Methodology/Principal Findings We spatially allocate two scenarios of 2000 2015 areal change in urban cropland at grid cell-level measure impact this on provision biodiversity. The...
Although nutrient enrichment frequently decreases biodiversity, it remains unclear whether such biodiversity losses are readily reversible, or critical transitions between alternative low- and high-diversity stable states that could be difficult to reverse. Our 30-year grassland experiment shows plant diversity decreased well below control levels after 10 years of chronic high rates (95-270 kg N ha(-1) year(-1)) nitrogen addition, did not recover 20 addition ceased. Furthermore, we found a...
Designing landscapes that can meet human needs, while maintaining functioning ecosystems, is essential for long-term sustainability. To achieve this goal, we must better understand the trade-offs and thresholds in provision of ecosystem services economic returns. end, integrate spatially explicit biophysical models to jointly optimize agricultural profit (sugarcane production cattle ranching), biodiversity (bird mammal species), freshwater quality (nitrogen, phosphorus, sediment retention)...
Inclusive wealth is a measure designed to address whether society on sustainable development trajectory. defined as the aggregate value of all capital assets. Increases in inclusive indicate an improved productive base capable supporting higher standard living future. To be truly inclusive, measures must include forms that contribute human well-being: capital, manufactured natural and social capital. Sustainability concerns have increased attention ways measuring We review various attempts...
The magnitude and pace of global climate change demand ambitious effective implementation nationally determined contributions (NDCs). Nature-based solutions present an efficient approach to achieving mitigation, adaptation resilience goals. Yet few nations have quantified the diverse benefits nature-based evaluate select ecosystem targets for their NDCs. Here we report on Belize's pursuit innovative, evidence-based target setting by accounting multiple blue carbon strategies. Through...
Landscape-level mitigation provides cost-effective conservation and can be used to promote sustainable development.
Best management practices (BMPs) play an important role in improving impaired water quality from conventional row crop agriculture. In addition to reducing nutrient and sediment loads, BMPs such as fertilizer management, reduced tillage, cover crops could alter the hydrology of agricultural systems reduce surface runoff. While attention is devoted benefits BMPs, potential co-benefits flood loss reduction are often overlooked. This study quantifies effects selected commonly applied on...
The Sustainable Development Goals (SDGs) emphasize the global and multi-dimensional nature of sustainability thus require improving our capacity to articulate trace impact ecosystem change measures human well-being. Yet, integrated these goals is challenging assess without similarly assessment tools. We present a new modeling toolkit, "Mapping Ecosystem Services Human well-being" (MESH), that integrates commonly used, stand-alone services (ES) models from InVEST suite quantify illustrate...
Significance Water quality is severely degraded in landscapes cultivated for intensive corn and soybean production. Current water policy focuses on reducing nutrient sediment losses from agricultural fields, yet recent studies have highlighted important roles of near-channel areas as sources sinks nitrogen. We developed an integrated modeling approach to assess cost-effectiveness tradeoffs watershed management scenarios that include a wide range both field actions, yielding estimates...
1 We provide the first theoretical analysis of multihost disease dynamics to incorporate social behaviour and contrasting rates within- between-group transmission. 2 A stochastic susceptible–infected–recovered (SIR) model transmission involving one three sympatric species was built mimic 1994 Serengeti canine distemper virus outbreak, which infected a variety carnivores with widely ranging structures. The successfully mimicked erratic discontinuous spatial pattern lion deaths observed in...
Forest loss and degradation globally has resulted in declines multiple ecosystem services reduced habitat for biodiversity. landscape restoration offers an opportunity to mitigate these losses, conserve biodiversity, improve human well-being. As part of the Bonn Challenge, a global effort restore 350 million hectares deforested degraded land by 2030, over 30 countries have recently made commitments national forest restoration. In order achieve goals, decision-makers require information on...
Abstract The restoration of ecosystems provides an important opportunity to improve the provision ecosystem services. Achieving maximum possible benefits from with a limited budget requires knowing which places if restored would produce best combination improved Using services assessment and optimization algorithm, we find choices that generate restoration. We applied set weights integrate multiple into unified approach optimal land option given those weights. then systematically vary Pareto...
Abstract Metacommunity theory predicts that the composition and diversity of a site depend on its characteristics those neighborhood. Dispersal between plots in field experiment could link responses observed focal plot to both treatment neighbors. However, diversity, composition, treatments neighboring are rarely included analyses experimental treatments. We analyzed spatially gridded grassland nitrogen addition found plant species richness were influenced not just by their but also number...
Life is full of risk. To deal with this uncertainty, many organisms have evolved bet-hedging strategies that spread risk through phenotypic diversification. These rates diversification can vary by orders magnitude in different species. Here we examine how key characteristics and organismal ecology affect the fitness consequences variation rate. We find rapid strongly favored when faced has a wide spatial extent, single disaster affecting large fraction population. This advantage especially...
Recognizing the substantial threats climate change poses to agricultural supply chains, companies around world are committing reducing greenhouse gas (GHG) emissions. Recent modeling advances have increased transparency of meat and ethanol industry where conventional production practices associated environmental impacts been characterized linked downstream points demand. Yet, date, information efforts neglected both spatial variability land use changes (LUCs) across highly heterogeneous...
Stresses like dietary restriction or various toxins increase lifespan in taxa as diverse yeast, Caenorhabditis elegans, Drosophila and rats, by triggering physiological responses that also tend to delay reproduction. Food odors can reverse the effects of restriction, showing key mechanisms respond information, not just resources. Such environmental cues predict population trends, individual prospects for survival When size is increasing, each offspring produced earlier makes a larger...
