From field measurements to national inventories and smart incentives—the SmartField approach for agricultural soil N 2 O fluxes
Significantly reducing greenhouse gas (GHG) emissions from agricultural production is crucial to limiting climate change. Fertilized soils are a major source of nitrous oxide (N 2 O), a potent GHG. Reducing N 2 O emissions is a key interest for many countries, including Denmark, where approximately 90% of N 2 O emissions originate from agricultural soils. Although the link between nitrogen (N) fertilization and N 2 O emissions is well-known, quan…
Global patterns of nitrogen saturation in forests
Synthesizing the evidence of nitrous oxide mitigation practices in agroecosystems
Nitrous oxide (N 2 O) emissions from agricultural soils are the main source of atmospheric N 2 O, a potent greenhouse gas and key ozone-depleting substance. Several agricultural practices with potential to mitigate N 2 O emissions have been tested worldwide. However, to guide policymaking for reducing N 2 O emissions from agricultural soils, it is necessary to better understand the overall performance and variability of mitigation practices and i…
Elevated CO2 negates O3 impacts on terrestrial carbon and nitrogen cycles
Increasing tropospheric concentrations of ozone (e[O$_{3}$]) and carbon dioxide (e[CO$_{2}$]) profoundly perturb terrestrial ecosystem functions through carbon and nitrogen cycles, affecting beneficial services such as their capacity to combat climate change and provide food. However, the interactive effects of e[O$_{3}$] and e[CO$_{2}$] on these functions and services remain unclear. Here, we synthesize the results of 810 studies (9,109 observat…

Tea-planted soils as global hotspots for N 2 O emissions from croplands
Tea-planted soils generally receiving high nitrogen (N) fertilizer doses are more vulnerable to acidification, and turn into significant sources of the potent greenhouse gas nitrous oxide (N 2 O). However, little is known about the magnitude of soil N 2 O emissions from global tea plantations. Based on a global meta-analysis of field experimental data collected from major tea growing countries, we quantify annual N 2 O emissions, calculate direct…

Closing maize yield gaps in sub-Saharan Africa will boost soil N2O emissions
In sub-Saharan Africa (SSA), the most important staple crop is maize; the production of which is dominated by smallholder farming systems using low external inputs (<10 kg N ha−1) resulting in low crop yields and large yield gaps (difference between actual and potential yields). To assess increases in soil N2O emissions when closing maize yield gaps by increased fertilizer use, we reviewed the literature, developed a relationship between yield ga…
Soil N intensity as a measure to estimate annual N2O and NO fluxes from natural and managed ecosystems
As natural and managed terrestrial ecosystems are major sources of the potent greenhouse gas nitrous oxide (N2O) and of the atmospheric pollutant nitric oxide (NO), predicting the source strengths of these ecosystems is central to understanding and sustainably managing the N-oxides fluxes. Here we reviewed 82 high temporal resolution datasets on N2O and 57 on NO fluxes collected from multi-site and multi-year field measurements, including grassla…
From research to policy
Towards a feasible and representative pan-African research infrastructure network for GHG observations
There is currently a lack of representative, systematic and harmonised greenhouse gas (GHG) observations covering the variety of natural and human-altered biomes that occur in Africa. This impedes the long-term assessment of the drivers of climate change, in addition to their impacts and feedback loops at the continental scale, but also limits our understanding of the contribution of the African continent to the global carbon (C) cycle. Given the…
Cold season soil NO fluxes from a temperate forest
Soils, and here specifically acidic forest soils exposed to high rates of atmospheric nitrogen deposition, are a significant source for the secondary greenhouse gas nitric oxide (NO). However, as flux estimates are mainly based on measurements during the vegetation period, annual NO emissions budgets may hold uncertainty as cold season soil NO fluxes have rarely been quantified. Here we analyzed cold season soil NO fluxes and potential environmen…
Regional nitrogen budget of the Lake Victoria Basin, East Africa
Using the net anthropogenic nitrogen input (NANI) approach we estimated the N budget for the Lake Victoria Basin in East Africa. The NANI of the basin ranged from 887 to 3008 kg N km−2 yr−1 (mean: 1827 kg N km−2 yr−1) for the period 1995–2000. The net nitrogen release at basin level is due primarily to livestock and human consumption of feed and foods, contributing between 69% and 85%. Atmospheric oxidized N deposition contributed approximately 1…
Reducing uncertainty in nitrogen budgets for African livestock systems
Livestock is poorly represented in N budgets for the African continent although some studies have examined livestock-related N flows at different levels. Livestock plays an important role in N cycling and therefore on N budgets including livestock-related flows. This study reviews the literature on N budgets for Africa to identify factors contributing to uncertainties. Livestock densities are usually modelled because of the lack of observational …
Short and long-term impacts of nitrogen deposition on carbon sequestration by forest ecosystems
The global nitrogen cycle in the twenty-first century
Global nitrogen fixation contributes 413 Tg of reactive nitrogen (N r ) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority of the transformations of anthropogenic N r are on land (240 Tg N yr −1 ) within soils and vegetation where reduced N r contributes most of the input through the use of fertilizer nitrogen in agriculture. Leakages from the use of fertilizer N r cont…
Toward a protocol for quantifying the greenhouse gas balance and identifying mitigation options in smallholder farming systems
Globally, agriculture is directly responsible for 14% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries (Vermeulen et al 2012). Agricultural intensification and expansion in these regions is expected to catalyze the most significant relative increases in agricultural GHG emissions over the next decade (Smith et al 2008, Tilman et al 2011). Farms in the developing countri…
Advancing national greenhouse gas inventories for agriculture in developing countries
Developing countries face many challenges when constructing national inventories of greenhouse gas (GHG) emissions, such as lack of activity data, insufficient measurements for deriving country-specific emission factors, and a limited basis for assessing GHG mitigation options. Emissions from agricultural production are often significant sources in developing countries, particularly soil nitrous oxide, and livestock enteric and manure methane, in…
Agroforestry with N2-fixing trees
Legume tree-based farming systems sit at a crucial nexus of agroecological sustainability. Their capacity to support microbial N2 fixation can increase soil nitrogen (N) availability and therefore improve soil fertility, crop yields, and support long-term stewardship of natural resources. However, increasing N availability oftentimes catalyzes the release of N into the surrounding environment, in particular nitrous oxide (N2O) — a potent greenhou…
