Abstract The EU Soil Strategy 2030 aims to increase soil organic carbon (SOC) in agricultural land enhance health and support biodiversity as well offset greenhouse gas emissions through sequestration.

Abstract Peatlands cover only 3–4% of the Earth’s surface, but they store nearly 30% global soil carbon stock. This significant is under threat as peatlands continue to be degraded at alarming rates around world. It has prompted countries worldwide establish regulations conserve and reduce emissions from this rich ecosystem. For example, EU implemented new rules that mandate sustainable management peatlands, critical reaching goal neutrality by 2050. However, a lack information on extent condition hindered development national policies restoration efforts. paper reviews current state knowledge mapping monitoring field sites globe identifies areas where further research needed. presents an overview different methodologies used map in nine countries, which vary definition peat peatland, coverage, detail.

Soil carbon storage results from interactions between ecological processes and contributes to the global chemical regulation of atmosphere, a vital ecosystem service. Within services approach, measuring soil stock is used as an indicator landscapes that function terrestrial sinks sources. models agricultural use national data are determine environmental benchmarks develop land-use management strategies for improved landscape-scale sequestration. The InVEST Carbon Storage model has been tool map based on these data. However, accuracy inventories Hungary unknown. In this study, two in were produced in-field collected sample collated inputs, mapped, compared, evaluated their usefulness planning maximizing sustainable policy development. Five spatial both landscapes, which showed great variation it. Aggregate potentially stored study areas also varied datasets used.

Assessment of the environmental kuznets curve within EU-27: Steps toward environmental sustainability (1990–2019)

Environmental Science and Ecotechnology, Год журнала: 2023, Номер 18, С. 100312 - 100312

Опубликована: Сен. 19, 2023

Reducing environmental pollution is a critical goal in global economics and economic development. The European Union (EU) faces challenges due to its development activities. Here we present comprehensive approach assess the impact of carbon dioxide (CO2) emissions, energy consumption (EC), population structure (POP), economy (GDP), policies on environment within EU using Kuznets curve (EKC). Our research reveals that between 1990 2019, EU-27 experienced an increase +1.18 million tonnes oil equivalent (Mtoe) per year (p < 0.05), while CO2 emissions decreased by 24.25 (Mt) 0.05). highest reduction occurred Germany (-7.52 Mt annually), lowest Latvia (-0.087 annually). empirical EKC analysis shows inverted-U shaped relationship GDP EU-27. Specifically, 1% results 0.705% emission, GDP2 leads 0.062% long run 0.01). These findings indicate has reached stage where growth positively impacts environment. Overall, this study provides insights into effectiveness mitigating degradation promoting green 27 countries.

The legacy of one hundred years of climate change for organic carbon stocks in global agricultural topsoils

Abstract Soil organic carbon (SOC) of agricultural soils is observed to decline in many parts the world. Understanding reasons behind such losses important for SOC accounting and formulating climate mitigation strategies. Disentangling impact last century’s change from effects preceding land use, management changes erosion difficult most likely impossible address observations outside warming experiments. However, record available every part globe, so potential effect on stocks can be modelled. In this study, an established validated FAO framework was used model global topsoil (0–30 cm) stock dynamics 1919 2018 as attributable change. On average, topsoils could have lost 2.5 ± 2.3 Mg C ha −1 (3.9 5.4%) with constant net primary production (NPP) or 1.6 3.4 (2.5 5.5%) when NPP considered modified by temperature precipitation. Regional variability explained complex patterns moisture, well initial stocks. small average been intrinsic persistent feature all climatic zones.

Climate Change Mitigation in Agriculture: Barriers to the Adoption of Carbon Farming Policies in the EU

Sustainability, Год журнала: 2023, Номер 15(13), С. 10452 - 10452

Опубликована: Июль 3, 2023

Climate change mitigation in the agricultural sector is essential to keep goal of limiting global warming 1.5 °C within reach. This article explores why there has been a limited adoption carbon farming policies EU, despite potential for emissions reductions and sequestration at farm level. Desk research revealed that EU Member States are increasingly setting sectoral climate targets agriculture, but lack addressing farming. Governments have largely refrained from using laws regulatory instruments, with strategies plans representing large majority EU. Moreover, interviews policymakers other stakeholders main barriers concerns over leakage competitive advantage, need just transition, structural issues food value chain. Despite being regarded by researchers as barrier farming, lobby not perceived policymakers, who emphasise importance involving farmers policy process. A key implication these findings form part wider system transformation order successfully contribute mitigation.

The U.S. government is planning significant reductions in greenhouse gas emissions as part of their nationally determined contribution to the Paris Agreement. plan includes a variety activities, one which enhancing carbon sinks soils through climate-smart agriculture program. nature soil along with market forces, cultural factors and other issues create challenges for program agriculture. These include quantification sequestration, targeting practice adoption that additional past adoption, ensuring gases do not increase practices. In addition, there are associated maintaining storage over long-time horizon; avoiding increases on non-participating lands. We review discuss options addressing direct regulations, subsidies tax incentives, taxes, credit offsets. None these policy interventions likely overcome all challenges, but ways limit risks pose each intervention. ability or mitigate careful design will largely determine how much sequestered soils, contributions reduction goal
