- Publication 16 August 2021 Mitigación con Sistemas Silvopastoriles en Latinoamérica: Aportes para la incorporación en los sistemas de Medición Reporte y Verificación bajo la CMNUCC En Latinoamérica el 46% de las emisiones de GEI proviene del cambio de usos de la tierra y el 20% de la agricultura, en donde el 58% y el 70% de las emisiones son debidas a la ganadería. El continuo crecimiento de este sector (+32% previsto al 2050) ha impulsado la expansión de la frontera agropecuaria en los bosques, generando múltiples impactos ambientales entre los cuales se encuentra la emisión de Gases Efecto Invernadero (GEI). Sin embargo, el sector tiene un alto potencial de mitigación…
- Publication 16 August 2021 Sustainability labelling as a tool for reporting the sustainable development impacts of climate actions relevant to Article 6 of the Paris Agreement The architecture of global carbon markets has changed significantly since the Paris Agreement and the 2030 Agenda for Sustainable Development Goals were both agreed in 2015. Voluntary, international cooperative approaches established in Article 6 of the Paris Agreement allow Parties to work together to achieve the targets set out in their respective Nationally Determined Contributions to limit global warming to an increase below 1.5–2 °C. In Article 6.4, a sustainable mitigation mechanism…
- Publication 16 August 2021 Ammonia and nitrous oxide emissions from a field Ultisol amended with tithonia green manure, urea, and biochar Short-term mitigation of ammonia (NH3) and nitrous oxide (N2O) emissions by biochar soil amendments has been reported, but limited knowledge of the mechanisms, particularly those associated with long term changes, remain relatively unknown. In order to investigate potential mechanisms and residual effect of biochar on NH3 and N2O emission, a 3-year field trial was set up on an Ultisol in western Kenya with a three-replicate full factorial treatment structure. The factors investigated include…
- Publication 16 August 2021 The co-evolution of learning mechanisms and technological capabilities: Lessons from energy technologies in emerging economies Despite a voluminous literature on firm-level technological capability building in developing countries, there is still limited knowledge about the relative importance of different learning mechanisms as firms deepen their technological capabilities. To address this knowledge gap, this paper investigates the sources of learning used by firms in the Malaysian biomass boiler industry and the Chinese wind turbine industry enabling them to advance from production capabilities to innovative…
- Publication 16 August 2021 Influence of urban form on the cooling effect of a small urban river Urban warming due to increased urbanization is becoming a serious environmental problem, requiring urban planners to consider heat mitigation strategies that reduce urban air temperature. Urban rivers play an important role in reducing urban heat through evaporation and transfer of sensible heat, known as the river cooling effect (RCE). We used detailed field measurements to calculate the river cooling intensity (RCI) and river cooling distance (RCD) for the Cheonggye River in Seoul, Korea in…
- Publication 16 August 2021 Incorporating uncertainty in national-level climate change-mitigation policy: possible elements for a research agenda Decision making for climate change management seldom incorporates uncertainty in the analysis that underpins the policy process. First, uncertainty is seldom characterised fully, and attempts to reduce uncertainty—when this is possible—are rare. Second, scientists are ill-equipped to communicate about uncertainty with policy makers, and policy makers most often favour pretended certainty over nuance and detail. Third, the uncertainty analysis that may have been conducted most often fails to…
- Publication 16 August 2021 The nexus between nationally determined contributions and technology needs assessments: a global analysis The role of technology in combatting climate change through mitigation and adaptation to its inevitable impacts has been acknowledged and highlighted by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). In the developing world, this has received particular attention through the technology needs assessment (TNA) process. As Parties put forward their national pledges to combat climate change, the scarcity of resources makes it important to assess (i) whether…
- News 9 July 2021 Pilot studies of transformational impact show the extent of climate policy ambition Four pilot cases have showed how looking at climate action policies through a Transformational Change lens can yield new insights into what works and why. The four cases cover different levels, sectors and stakeholders, and have used a new methodology, developed by UNEP DTU Partnership experts, to assess both new and emerging climate policies. The Transformational Change Methodology is a stepwise approach to determine the extent to which a policy is truly transformational in terms of delivering…
