315 Implementation of Large-Scale Climate-Smart Agriculture Practices and Research on Beef and Bison Grazing Lands

Abstract Today’s livestock producers face increasing public scrutiny because animal agriculture is often cited as a major contributor to greenhouse gas (GHG) emissions. However, this negative perception does not take into account the carbon (C) sequestration benefits of grazing livestock nor that grazing lands account for 25% of the global soil sequestration potential of soil C storage. Grazing beef cattle and bison are key to healthy grassland ecosystems and provide the most nutrient dense source of protein available for human consumption. Beef and bison producers who graze their livestock are widely recognized as environmental stewards because they use sustainable grazing practices that maintain grassland health. These practices are considered climate-smart agriculture (CSA) because they promote soil C sequestration and resilience to increased climate variability. Yet, these same producers are generally overlooked in GHG reduction and C sequestration incentives because of a relative lack of cost-effective methods to measure C and GHG sinks and sources. Emerging technologies are beginning to bridge that gap by paving the way to develop, implement, and monitor CSA practices. Furthermore, rangelands in the U.S. dedicated to supporting forage-based livestock production amount to nearly 940 million acres. This is more than double the acres dedicated to row crops and represents enormous potential to contribute to U.S. climate change commitments. Successful implementation and monitoring of CSA land management practices creates potential to develop climate-smart livestock commodities that sustainably provide economic incentives to producers operating resilient livestock grazing systems. Recently, South Dakota State University, along with ten external partners, was awarded a CSA commodity development grant by the USDA and NRCS focused on CSA-raised grazing beef cattle and bison in the Northern Great Plains. Specific objectives include: 1) developing and implementing existing and novel CSA practices alongside custom grazing plans; 2) measuring, monitoring, reporting, and verifying CSA practice impacts on GHG emissions, C sequestration, and ecosystem biodiversity of plants, arthropods, and wildlife; and 3) creating sustainable, value-added market opportunities for producers using CSA practices. To achieve these objectives, the project team is partnering with producers throughout the Northern Great Plains and beyond and will provide incentives for CSA practice implementation. Additionally, emerging and novel technologies will be used to collect large-scale data across producer operations and test sites to determine and refine GHG and C sequestration estimates associated with range beef cattle and bison systems. The long-term goal of this project is to provide CSA beef and bison producers with sustainable, value-added market opportunities that align with consumer preferences and demand.

Health and climate change: adaptation policy in Aotearoa New Zealand.

Recent extreme weather events attributable to climate change have major implications for policy. Here we summarize and evaluate the current state of climate change adaptation policy, from a health perspective, for Aotearoa New Zealand, based on government sources. Legislation relating to both environmental management and health are currently subject to major reforms. At present, adaptation policy emphasises protection of health care facilities from climate extremes; there is insufficient attention paid to broader determinants of health. We argue for greater health input into adaptation planning. Without intersectoral collaboration, contributions from diverse communities, and better support of indigenous solutions, climate change policy is unlikely to achieve effective health outcomes and there is a risk that climate change will exacerbate inequities. We recommend that the Climate Change Commission engage formally and directly with health bodies to strengthen the Commission's advice on the implications of climate change, and of national climate change policies, on health and equity. Climate resilient development does not occur without better public health. For this reason, the health sector has a critical role in the development and implementation of adaptation policy.

Resource nationalism and energy transitions in lower-income countries: the case of Tanzania

ABSTRACT As the world approaches the 2030 year marker for the implementation of 17 Sustainable Development Goals (SDGs) as defined by the United Nations, the global urgency for sustainable and energy sources grows. Lower-income countries, however, confront a choice between cleaner energy and ensuring cheap and reliable energy. This raises the question of how some countries can find a balance between meeting their global climate change commitments and meeting urgent energy generation needs. This article uses resource nationalism as a lens to examine Tanzania’s energy transition dynamics. It seeks to understand why renewable sources such as wind and solar have been promoted in government policy but have not attracted much developmental support and investment. The authors argue that resource nationalism provides context within which to understand why the state has been quick to promote energy projects (notably geothermal, coal, natural gas and hydroelectric) where it has direct investment interests, as opposed to large wind and solar projects where private – often foreign – investors are dominant.

The challenges of implementing adaptation actions in Scotland’s public sector

This research examines the progress made by the public sector in Scotland from risk assessment to adaptation planning and implementation. We highlight some key challenges faced by the public sector in Scotland that are leading to a lack of progress in the adaptation space as noted in a recent UK Climate Change Committee report, “Is Scotland climate ready? – 2022 Report to Scottish Parliament”. This report highlighted the lack of analysis of the adaptation section of public bodies duties reports in Scotland and our research is the first in-depth analysis of this section at time of writing supplemented by interviews with a range of public sector bodies. The key research questions we consider are: “What tools, frameworks, data and knowledge are currently being used to conduct risk assessments for adaptation?”; “What kind of tools, frameworks, knowledge and data may be helpful for decision makers in this space?” and “What challenges and barriers exist for public sector bodies throughout their adaptation journeys?” By first setting out the key challenges currently facing the public sector in Scotland, we then present a range of potential solutions that could be implemented in Scotland to increase adaptation action. This study can help bridge the gap between climate science and decision makers by making it clearer what the requirements are for future tools, models and data to help accelerate adaptation action and how it is reported on and evaluated.

Enabling a National Program for Ecological Corridors in Canada in support of biodiversity conservation, climate change adaptation, and Indigenous leadership

Identification and protection of important areas to improve connectivity in support of biodiversity conservation, climate change adaptation, and Indigenous Rights has been a key aspect in the Convention on Biological Diversity's policymaking for over two decades. Target 3 of the recently adopted Kunming-Montreal Global Biodiversity Framework reiterated this need, calling on nations to conserve 30 % of terrestrial and marine areas by 2030 through “well-connected” and equitably governed systems of protected and conserved areas, among other considerations. In response to this call, Canada has initiated and amplified a new National Program for Ecological Corridors to enable collaborative efforts to protect and restore ecological connectivity across the country. Using multiple methods, including a literature review and a combination of interviews and workshops with conservation stakeholders, seven enabling conditions to support the effective and equitable implementation of the program were identified. These enabling conditions encompass respectful and meaningful engagement of and inclusion of Indigenous Peoples; establishing high-level commitment and vision, consistent with international and national biodiversity conservation and climate change commitments, supported by predictable, sustained funding and enabling legislation; and developing an appropriately scaled national corridor vision and supporting criteria and indicators to effectively monitor and communicate outcomes for biodiversity and people. Supporting mechanisms and strategies are detailed that can be used to effectively enable a national corridor program in Canada, providing early lessons learned and next steps for consideration by the wider global conservation community who are also striving to meet their own biodiversity and climate change adaptation goals.

Can the UK meet the World Health Organization PM2.5 interim target of 10 μg m−3 by 2030?

The recent United Kingdom (UK) Environment Act consultation had the intention of setting two targets for PM2.5 (particles with an aerodynamic diameter less than 2.5 μm), one related to meeting an annual average concentration and the second to reducing population exposure. As part of the consultation, predictions of PM2.5 concentrations in 2030 were made by combining European Union (EU) and UK government’s emissions forecasts, with the Climate Change Committee’s (CCC) Net Zero vehicle forecasts, and in London with the addition of local policies based on the London Environment Strategy (LES). Predictions in 2018 showed 6.4% of the UK’s area and 82.6% of London’s area had PM2.5 concentrations above the World Health Organization (WHO) interim target of 10 μg m−3, but by 2030, over 99% of the UK’s area was predicted to be below it. However, kerbside concentrations in London and other major cities were still at risk of exceeding 10 μg m−3. With local action on PM2.5 in London, population weighted concentrations showed full compliance with the WHO interim target of 10 μg m−3 in 2030. However, predicting future PM2.5 concentrations and interpreting the results will always be difficult and uncertain for many reasons, such as imperfect models and the difficulty in estimating future emissions. To help understand the sensitivity of the model’s PM2.5 predictions in 2030, current uncertainty was quantified using PM2.5 measurements and showed large areas in the UK that were still at risk of exceeding the WHO interim target despite the model predictions being below 10 μg m−3. Our results do however point to the benefits that policy at EU, UK and city level can have on achieving the WHO interim target of 10 μg m−3. These results were submitted to the UK Environment Act consultation. Nevertheless, the issues addressed here could be applicable to other European cities.

The relative importance of carbon markets to the waste management sector’s future contribution to climate change commitments under the Paris Agreement: insights from Australia

This paper presents research that analyses the relative importance of carbon markets to sustainable waste management projects in Australia. It identifies that a large proportion of carbon credits issued have been generated by landfill to electricity projects, which effectively rely on the continuation of landfilling practices. More ambition is needed to realise the potential of circular solutions that reduce, recover and utilise waste before disposal.The research also shows that, through modelling the financial performance of two theoretical waste to energy projects that would result in diversion of waste from landfill, simultaneous use of revenue support mechanisms (carbon markets and renewable energy certificate programs), cost of capital support programs (like concessional finance) and avoided landfilling levies in the deployment of waste management projects can be justified. The paper illustrates the significant contribution carbon revenues can make to project additionality at the investment-decision stage, adding between 2–10% to ex-ante estimates of pre-tax equity returns. This shows that a project’s additionality is not invalidated in cases where it accesses more than one support mechanism.There are many policy and practice applications for these findings in Australia and globally. They include within ongoing international efforts to define modalities for the new Article 6.4 mechanism under the Paris Agreement, reforms to how developing countries access to climate finance (including, but not limited to, the Bridgetown Initiative 2.0 (The Bridgetown Initiative 2.0: https://www.un.org/sustainabledevelopment/blog/2023/04/press-release-with-clock-ticking-for-the-sdgs-un-chief-and-barbados-prime-minister-call-for-urgent-action-to-transform-broken-global-financial-system/)); and through the domestic policies and mechanisms countries adopt so they are fit-for-purpose to support implementation of Nationally Determined Contributions (NDC).

Driving businesses towards a better climate: Macro and micro mechanisms to protect the planet

AbstractThis study examines whether corporate commitment to climate change is driven by country‐level factors related to cultural values and the legal system (LS) of a country. We also investigate the impact of corporate governance strength on climate change commitment and the extent to which there are moderating effects between corporate governance and cultural and LS influences. We use a large dataset of 21,564 firm‐year observations of companies operating in the United States, UK, and China for the period 2013 to 2020 and develop a unique measure for climate change commitment using different proxies for measuring climate change practices. We find variations in climate change commitment among the three countries and that cultural values and LSs affect corporate commitment to climate change. Companies located in a socially oriented society, which are transparent and characterized by long‐term orientation, are more strongly involved in climate change actions. The strength of corporate governance increases corporate commitment to climate change. Corporate governance also moderates some of the detrimental cultural influences on climate change commitment. These findings have implications for managers as they reveal that macro‐level factors affect behavior and that corporate governance can help to moderate these factors.

Life‐Cycle‐Assessment of purlin systems: the influence of the low carbon high strength steels in CO2eq. emissions

AbstractDue to the decarbonization of the energy sector, embodied carbon has been recognized as the dominant climate impact driver. In response, countries are currently accelerating their efforts to comply with climate change commitments and regulations, pressure grows for the construction sector to reduce its impact rapidly.In the present paper, the life cycle assessments (LCA) of purlin roof systems, used as secondary structural elements on single‐story industrial buildings, are compared. Three structural materials are considered: metallic‐coated structural steel, reinforced concrete, and structural timber. In addition, different steel grades are compared to highlight the environmental benefits of using high‐strength steels (HSS) allowing weight‐optimized design.The LCA focuses on the product stage (modules A1‐A3), transport (module A4), end‐of‐life (module C), and the benefits and loads beyond the system boundary (module D). The life cycle inventory (LCI) is composed of construction environmental product declarations (EPD) published according to EN 15804. All the LCA evaluations are performed using the commercial software One Click LCA following the recommendations of EN 15978.

Framing Climate Litigation in Individual Communications of the African Human Rights System: Claw-Backs and Substantive Divergences

Abstract Climate litigation is anticipated to continue expanding, especially related to the interface with the human rights of vulnerable populations and the adequacy of states’ efforts to adopt and implement climate laws. While the possibility of climate-related litigation is envisaged before the African Human Rights System (AHRS), there is no pioneering case on climate change at that level yet. Essential rights that may be relevant in climate change litigation in the AHRS are not yet tested and often have claw-back clauses that have limits imposed by national legislation. Also, climate change commitments that may link to human rights are under a regime outside the AHRS. These developments may generate conceptual divergences regarding a state’s sovereign right and climate justice in future climate litigation within the AHRS. This article explores the potential application of claw-back clauses and divergent views on states’ sovereign rights and climate justice in climate change instruments that may feature in individual communications at the AHRS.

The Probabilistic Risk Assessment Imperative in Philippine Climate Change Adaptation-Disaster Risk Reduction (CCA-DRR) Efforts

The Philippines is ranked first in the World Risk Index 2022 according to the Germany-based Bündnis Entwicklung Hilft and the Institute for International Law of Peace and Armed Conflict (IFHV). The country will likely remain at the top rank of the global risk index over the next few decades, mainly due to the Philippines being in the Pacific Typhoon Belt, where the adverse impacts of climate change are predicted to get worse. To solve this predicament, intensive preparations through development planning are needed, and Probabilistic Risk Assessment (PRA) is required to capture and anticipate future hazards bigger than the historical record. The probabilistic approach is recognized in the Philippine Development Plan 2017-2022 and 2023-2028, the 2019 National Climate Risk Management Framework Policy of the Climate Change Commission (CCC), and the United Nations Disaster Risk Reduction (UNDRR) document entitled, “Why Invest in Probabilistic Risk Assessment?” as necessary for effective climate change adaptation actions. However, the Philippines has yet to realize the nationwide-scale implementation of PRAs in our CCA-DRR efforts, despite it being a strategy recommended by the national government to effectively address worsening natural hazard impacts that severely hamper national development. This paper highlights the importance of PRA in the context of Philippine Climate Change Adaptation and Disaster Risk Reduction (CCA-DRR) efforts to lower the cost of damage from floods, rainfall-triggered landslides, and storm surges and help communities attain their sustainable development goals. We recommend that these policies be systematically implemented without any more delay.

How civil engineers can help the UK deliver a resilient, net-zero-emissions energy system

UK’s Climate Change Committee says a resilient, net-zero-emissions power system can be built by 2035 to meet national sustainability targets, but not at the current pace of delivery. Committee member Richard Dawson says civil engineers have a crucial role to play in meeting the challenge.

Assessing the economic implications of national climate change mitigation policies on cities: A CGE analysis of Auckland, New Zealand

Computable General Equilibrium (CGE) models have proven to be instrumental in the climate policy literature. Although their use at the sub-national level has increased, their application to assess the implications of national climate policies on cities is scarce due to the low availability of city-level economic and environmental data. Cities could play an instrumental role in the fight against climate change as they are home to more than half of the world population, generate more than 80% of global Gross Domestic Product (GDP) and are responsible for 75% of global greenhouse gas (GHG) emissions. National CGE assessments of climate policies overlooking cities could result in missing major opportunities to achieve ambitious reduction targets considering that cities are centres of innovation and wealth. Hence, the objective of this study is to fill that gap in the literature by developing and using a recursive dynamic, multi-regional CGE model to link a city's economy to the rest of the nation to assess the direct and indirect economic impacts from national GHG emissions reduction pathways. The city of Auckland, New Zealand (NZ) has been used as a case study due to the city's proactive climate mitigation plans. The model and scenarios used resemble the ones developed by the New Zealand Climate Change Commission (CCC) to inform national policy advise provided to the government. Additional scenarios were developed to incorporate Auckland's growth and climate strategies. The results showed that in contrast to the rest of New Zealand, the impacts on the Auckland economy are more pronounced as reflected by the more drastic percent changes (with respect to baseline) of the regional GDP (−6% for Auckland and −1% for NZ) and consumer welfare (−5% for Auckland and 1% for NZ). The more pronounced impacts on Auckland are due to the difference in profile emissions (e.g., urban versus rural sectors), fewer low-emission technological alternatives (e.g., rural technologies do not cater to urban sectors' needs), and indirect impacts from importing agricultural products with a higher price tag due to rising GHG prices. This study's contribution in the climate policy literature is to serve as evidence and precedent to carefully evaluate the nuances encountered in complex urban systems when developing national climate policies considering that the number of countries establishing legally binding reduction targets is continually increasing.

Taking National Climate Change Gender Action Plans to heart – three steps to activate a plan

abstract Sometimes the policy and material discourses around climate change may feel far removed from the daily realities of people, whose experiences are intensely local and whose time horizons are immediate. Perhaps there are more creative ways to bring policy closer to the homestead, so that people better understand the implications of public policy and are better equipped to hold governments responsible to stated commitments. Climate Change Gender Action Plans may present both an opportunity and effective entry point for collective understandings and movement building – because ‘gender’ has become the catch-all word that embraces a non-patriarchal, pro-feminist approach to fundamental change, and a creative avenue to innovative solutions to the multiple risks associated with the changing climate. In Belize, the National Climate Change Office (NCCO) is the Government’s secretariat for climate change, acting as the operational arm of the Belize National Climate Change Committee, and tasked with developing the National Climate Change Gender Action Plan in 2021. This focus shares some perspectives on the opportunity such official documents offer grassroots climate change activists and movements for change; and the importance of civil society ‘activating and enlivening’ these plans towards their collective visions. Taking Belize’s recently outlined Gender Action Plan as the backdrop, I highlight important aspects of the plan that are relevant to African nation states and consider how local climate change activists may breathe life into a public document that so far exists only on paper. I also took the liberty to invite Destiny Wagner, Miss. Earth (Belize 2021-22), to offer additional perspectives as an appointed ambassador for the environment, one of whose roles is to raise awareness of climate change and ecological issues in Belize.

Integration criteria of offshore wind farms in the landscape: Viewpoints of local inhabitants

The offshore wind energy sector will flourish in the next few decades to meet global climate change commitments and energy demand. All EU Member States are required to develop marine spatial planning in order to facilitate the transition to a green economy. Even though these proposed offshore wind farms are essential for the energy transition, the visual impact of their implementation could serve as an obstacle to their deployment.A methodological framework is proposed to assess the visual impact of offshore wind farms. The current paper quantifies their visual impact, compares the results with nearby citizens' opinions, and proposes a realistic approach. Personal interviews took place in August to meet as many people as possible since these villages are primarily touristic.In both examined scenarios, according to the results of the methodology (Greek legislation) the first limitation is met, so there is no or minimal visual impact. Furthermore, the respondents replied that they would not experience any optical disturbance from an offshore wind farm in their region. Additionally, according to the respondents, 64% are positive or very positive about renewable energy exploitation, and only 11% are against it regardless of their age.

Planting hedgerows: Biomass carbon sequestration and contribution towards net-zero targets

Agroforestry practices, such as hedgerow planting, are widely encouraged for climate change mitigation and there is an urgent need to assess their contribution to national ‘net-zero’ targets. This study examined the impact that planting hedgerows at different rates could make to UK net-zero goals over the next 40 years, with a focus on 2050. We analysed the carbon (C) content of native hedgerow species and determined hedge aboveground biomass (AGB) C stock via destructive sampling of hedges of known ages. AGB C stocks ranged from 8.34 Mg C ha−1 in the youngest hedges, to 40.42 Mg C ha−1 in old ones. Knowing the age of the hedgerows, we calculated their annual average AGB C sequestration rate, which was highest in young hedges (2.09 Mg C ha−1 yr−1), and lowest in 39 year old mature, regularly trimmed hedgerows (0.86 Mg C ha−1 yr−1). We present a time series of the annual AGB C sequestration rate change between hedge age categories, which increases from 2.09 Mg C ha−1 yr−1 in the first 6 years after planting, to 2.26 Mg C ha−1 yr−1 in the next 6 years, and then decreases to 0.43 Mg C ha−1 yr−1 between years 13 and 40. Our results indicate that, if encouraged widely, hedgerow planting can be a valuable tool for atmospheric CO2 capture and storage, contributing towards net-zero targets. However, current planting rates (1778.8 km yr−1) are too low to reach the net-zero goal set by the UK Climate Change Committee of increasing hedgerow length by 40 % by 2050. An increased planting rate of 7148.1 km yr−1 will achieve this goal by 2050, and, over 40 years, store 3.41 Tg CO2 in hedge AGB, or 10.13 Tg CO2 in hedge total biomass and in the soil, annually offsetting 1.5 %–4.5 % of UK annual agricultural CO2 emissions.

Climate justice in Vietnam’s green transformation: A three-dimensional analysis of the green growth and climate change mitigation sectors

Vietnam has been making great strides in promoting a low-carbon development pathway to ensure high growth rates, environmental protection, and fulfilment of international climate change commitments. These efforts are concretized in the form of a green transformation policy framework of which the most important components are the National Green Growth Strategy for the period 2021-2030 and the National Climate Change Strategy for the period up to 2050. As these policies employ an integrated approach that aim to achieve economic growth and climate change mitigation simultaneously, there is a possibility that the social pillar of sustainable development may be neglected, potentially leading to issues with equity and fairness in planning and implementing concrete missions and tasks. This article seeks to determine whether this is the case by assessing how three dimensions of climate justice -namely recognition justice, procedural justice and distributive justice - are reflected in the Green Growth and Climate Change Strategies.

The prospect of direct air capture for energy security and climate stability

Energy policies aim at securing energy supply through domestic production or imports have significant consequences for climate change and its long-term impacts on the economy. Recent European energy crisis as a result of extensive reliance on imported Russian natural gas has highlighted the European Union (EU) energy vulnerability and has challenged its climate change commitments. While switching to alternative domestic fossil fuel sources such as coal in some member states has put the EU climate ambitions in jeopardy, it has also provided new opportunities for up-scaling renewable technologies as well as climate stability measures such as direct air capture (DAC). This paper examines the interaction between energy policy and climate stability by considering imported natural gas, domestic coal production, and possible DAC deployment in the EU under two scenarios of full cooperation and full competition among the EU member states. The results suggest that while cooperation induces higher reliance on imported energy, it also provides a strong incentive for DAC uptake. Competition on the other hand, may result in more reliance on domestic coal production and worse climate change outcomes despite the availability of DAC. Therefore, as the EU is striving for a more perfect union, it should consider better alignment of its short-term energy security policies with long-term climate stability ambitions.

Boiler Upgrade Scheme Is Failing, Says Lords Committee

The House of Lords Environment and Climate Change Committee has concluded that the government’s Boiler Upgrade Scheme is failing to deliver on its objectives.
