- Publication 16 August 2021 Agency in transition: The role of transnational actors in the development of the off-grid solar PV regime in Uganda While the sustainability transitions literature has highlighted the importance of agency in technological change, there is still limited understanding of the role of transnational actors, such as development agencies, which tend to be key drivers of energy transitions in low-income countries. This paper aims to fill this gap by investigating the role of transnational actors in the development of off-grid solar PV regime in Uganda, from the early 1980s to 2017. Specifically, we develop a…
- Publication 16 August 2021 How to Effectively Enhance Sustainable Livelihoods in Smallholder Systems: A Comparative Study from Western Kenya Increasing communities’ adaptive capacity is crucial to enhancing the sustainability of livelihoods and landscapes in smallholder systems. This study evaluates the contributions of an asset-based community-driven local development project, which has an objective to enhance farmer livelihoods through context-specific agricultural and agroforestry training, in line with farmers’ identities, interests, and preferences. The project was implemented in two areas of the wider Nyando river basin: the…
- Publication 16 August 2021 A pathway design framework for national low greenhouse gas emission development strategies The Paris Agreement introduces long-term strategies as an instrument to inform progressively more ambitious emission reduction objectives, while holding development goals paramount in the context of national circumstances. In the lead up to the twenty-first Conference of the Parties, the Deep Decarbonization Pathways Project developed mid-century low-emission pathways for 16 countries, based on an innovative pathway design framework. In this Perspective, we describe this framework and show how…
- Publication 16 August 2021 Nitrogen turnover and N2O/N2 ratio of three contrasting tropical soils amended with biochar Biochar has been reported to reduce emission of nitrous oxide (N2O) from soils, but the mechanisms responsible remain fragmentary. For example, it is unclear how biochar effects on N2O emissions are mediated through biochar effects on soil gross N turnover rates. Hence, we conducted an incubation study with three contrasting agricultural soils from Kenya (an Acrisol cultivated for 10-years (Acrisol10); an Acrisol cultivated for over 100-years (Acrisol100); a Ferralsol cultivated for over 100…
- 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…
