Agricultural intensification offers potential to grow more food while reducing the conversion of native ecosystems to croplands. However, intensification also risks environmental degradation through emissions of the greenhouse gas nitrous oxide (N2O) and nitrate leaching to ground and surface waters. Intensively-managed croplands and nitrogen (N) fertilizer use are expanding rapidly in tropical regions. We quantified fertilizer responses of maize yield, N2O emissions, and N leaching in an Amazon soybean-maize double-cropping system on deep, highly-weathered soils in Mato Grosso, Brazil. Application of N fertilizer above 80 kg N ha−1 yr−1 increased maize yield and N2O emissions only slightly. Unlike experiences in …

National Contributions To Climate Change Mitigation From Agriculture: Allocating A Global Target, Meryl Breton Richards, Eva Wollenberg, Detlef Van Vuuren Nov 2018

National Contributions To Climate Change Mitigation From Agriculture: Allocating A Global Target, Meryl Breton Richards, Eva Wollenberg, Detlef Van Vuuren

Rubenstein School of Environment and Natural Resources Faculty Publications

Globally, agriculture and related land use change contributed about 17% of the world’s anthropogenic GHG emissions in 2010 (8.4 GtCO2e yr−1), making GHG mitigation in the agriculture sector critical to meeting the Paris Agreement’s 2°C goal. This article proposes a range of country-level targets for mitigation of agricultural emissions by allocating a global target according to five approaches to effort-sharing for climate change mitigation: responsibility, capability, equality, responsibility-capability-need and equal cumulative per capita emissions. Allocating mitigation targets according to responsibility for total historical emissions or capability to mitigate assigned large targets for agricultural emission reductions to North America, Europe and …

Recent developments in machine learning have expanded data-driven modelling (DDM) capabilities, allowing artificial intelligence to infer the behaviour of a system by computing and exploiting correlations between observed variables within it. Machine learning algorithms may enable the use of increasingly available ‘big data’ and assist applying ecosystem service models across scales, analysing and predicting the flows of these services to disaggregated beneficiaries. We use the Weka and ARIES software to produce two examples of DDM: firewood use in South Africa and biodiversity value in Sicily, respectively. Our South African example demonstrates that DDM (64–91% accuracy) can identify the areas where …

Seizing Opportunities To Diversify Conservation, Rachelle K. Gould, Indira Phukan, Mary E. Mendoza, Nicole M. Ardoin, Bindu Panikkar Jul 2018

Seizing Opportunities To Diversify Conservation, Rachelle K. Gould, Indira Phukan, Mary E. Mendoza, Nicole M. Ardoin, Bindu Panikkar

Rubenstein School of Environment and Natural Resources Faculty Publications

Conservation Letters published by Wiley Periodicals, Inc. This article identifies, and offers several ways to address, a serious, persistent issue in conservation: low levels of diversity in thought and action. We first describe the lack of diversity and highlight the continued separation of the environmental conservation and environmental justice movements. We then offer—based on previous research and our collective experience—two suggestions for how to increase inclusivity (a step farther than increasing diversity) in holistic ways. We suggest that embracing narrative, including historical narrative that can be profound and painful, may be essential to addressing this deeply rooted issue. We also …

Rumen microorganisms are the origin of many bioactive fatty acids (FA) found in ruminant-derived food products. Differences in plant leaf anatomy and chemical composition between cool- and warm-season pastures may alter rumen microorganisms, potentially enhancing the quantity/profile of bioactive FA available for incorporation into milk. The objective of this study was to identify rumen bacteria and protozoa and their cellular FA when cows grazed a warm-season annual, pearl millet (PM), in comparison to a diverse cool-season pasture (CSP). Individual rumen digesta samples were obtained from five Holstein cows in a repeated measures design with 28-day periods. The treatment sequence was …

Successfully meeting the mitigation and adaptation targets of the Paris Climate Agreement (PA) will depend on strengthening the ties between forests and agriculture. Climate-smart land use can be achieved by integrating climate-smart agriculture (CSA) and REDD+. The focus on agriculture for food security within a changing climate, and on forests for climate change mitigation and adaptation, can be achieved simultaneously with a transformational change in the land-use sector. Striving for both independently will lead to competition for land, inefficiencies in monitoring and conflicting agendas. Practical solutions exist for specific contexts that can lead to increased agricultural output and forest protection. …

© The Ecological Society of America Biodiversity offsets are most commonly used to mitigate the adverse impacts of development on biodiversity, but some offsets are now also designed to support ecosystem services (ES) goals. Here, we assemble a global database of biodiversity offsets (n = 70) to show that 41% already take ES into consideration, with the objective of enhancing cultural, regulating, and provisioning services. We found that biodiversity offsets were more likely to consider ES when (1) development projects reported impacts on services, (2) offsets had voluntary biodiversity goals, and (3) conservation organizations were involved. However, offsets that considered …

This article analyses the greenhouse gas (GHG) impact potential of improved management practices and technologies for smallholder agriculture promoted under a global food security development program. Under 'business-as-usual' development, global studies on the future of agriculture to 2050 project considerable increases in total food production and cultivated area. Conventional cropland intensification and conversion of natural vegetation typically result in increased GHG emissions and loss of carbon stocks. There is a strong need to understand the potential greenhouse gas impacts of agricultural development programs intended to achieve large-scale change, and to identify pathways of smallholder agricultural development that can achieve food …

The Ecology And Conservation Of Cuba’S Coastal And Marine Ecosystems, Joe Roman Apr 2018

The Ecology And Conservation Of Cuba’S Coastal And Marine Ecosystems, Joe Roman

Rubenstein School of Environment and Natural Resources Faculty Publications

Cuba has some of the most well-protected coastal ecosystems in the Caribbean Sea, with strong marine policies and legislation, including a system of marine protected areas intended to cover 25% of its insular shelf. The “crown jewel” of the system, Jardines de la Reina National Park, has near pristine levels of apex predators and well-preserved coral reefs. Yet overfishing, illegal fishing, land-based pollution, and global changes, including increased bleaching events and more intense hurricanes, are widespread stressors and major threats to marine ecosystems. Limited resources have hindered Cuba’s ability to address these threats. Despite having numerous shared species and resources …

Relationship Between Food Waste, Diet Quality, And Environmental Sustainability, Zach Conrad, Meredith T. Niles, Deborah A. Neher, Eric D. Roy, Nicole E. Tichenor, Lisa Jahns

Rubenstein School of Environment and Natural Resources Faculty Publications

Improving diet quality while simultaneously reducing environmental impact is a critical focus globally. Metrics linking diet quality and sustainability have typically focused on a limited suite of indicators, and have not included food waste. To address this important research gap, we examine the relationship between food waste, diet quality, nutrient waste, and multiple measures of sustainability: use of cropland, irrigation water, pesticides, and fertilizers. Data on food intake, food waste, and application rates of agricultural amendments were collected from diverse US government sources. Diet quality was assessed using the Healthy Eating Index-2015. A biophysical simulation model was used to estimate …

Spatial Analysis Of Ecosystem Service Relationships To Improve Targeting Of Payments For Hydrological Services, Pierre Mokondoko, Robert H. Manson, Taylor H. Ricketts, Daniel Geissert Feb 2018

Spatial Analysis Of Ecosystem Service Relationships To Improve Targeting Of Payments For Hydrological Services, Pierre Mokondoko, Robert H. Manson, Taylor H. Ricketts, Daniel Geissert

Rubenstein School of Environment and Natural Resources Faculty Publications

Payment for hydrological services (PHS) are popular tools for conserving ecosystems and their water-related services. However, improving the spatial targeting and impacts of PHS, as well as their ability to foster synergies with other ecosystem services (ES), remain challenging. We aimed at using spatial analyses to evaluate the targeting performance of Mexico's National PHS program in central Veracruz. We quantified the effectiveness of areas targeted for PHS in actually covering areas of high HS provision and social priority during 2003-2013. First, we quantified provisioning and spatial distributions of two target (water yield and soil retention), and one non-target ES (carbon …

Ecology And Economics Of Using Native Managed Bees For Almond Pollination, Insu Koh, Eric V. Lonsdorf, Derek R. Artz, Theresa L. Pitts-Singer, Taylor H. Ricketts Jan 2018

Ecology And Economics Of Using Native Managed Bees For Almond Pollination, Insu Koh, Eric V. Lonsdorf, Derek R. Artz, Theresa L. Pitts-Singer, Taylor H. Ricketts

Rubenstein School of Environment and Natural Resources Faculty Publications

Native managed bees can improve crop pollination, but a general framework for evaluating the associated economic costs and benefits has not been developed. We conducted a cost–benefit analysis to assess how managing blue orchard bees (Osmia lignaria Say [Hymenoptera: Megachildae]) alongside honey bees (Apis mellifera Linnaeus [Hymenoptera: Apidae]) can affect profits for almond growers in California. Specifically, we studied how adjusting three strategies can influence profits: (1) number of released O. lignaria bees, (2) density of artificial nest boxes, and (3) number of nest cavities (tubes) per box. We developed an ecological model for the effects of pollinator activity on …

Increasing weather risks threaten agricultural production systems and food security across the world. Maintaining agricultural growth while minimizing climate shocks is crucial to building a resilient food production system and meeting developmental goals in vulnerable countries. Experts have proposed several technological, institutional, and policy interventions to help farmers adapt to current and future weather variability and to mitigate greenhouse gas (GHG) emissions. This paper presents the climate-smart village (CSV) approach as a means of performing agricultural research for development that robustly tests technological and institutional options for dealing with climatic variability and climate change in agriculture using participatory methods. It …
