Ethiopia, Kenya, Rwanda, Zambia and Senegal have communicated agriculture sector specific mitigation measures in their updated Nationally Determined Contributions (NDC’s). All five countries have unconditional economy wide emission reduction targets of 29% – 54% in 2030 relative to their BAU (or 2010 base year emissions for Zambia).

Including agriculture specific mitigation measures in the NDC is especially significant given agriculture emissions are key drivers of emissions across the five African countries, albeit responsible for variable proportions of the total emission profile. Implementing these mitigation measures will face different barriers in each country but communicating the intention to mitigate agriculture emissions is the first step.

Key points from each country’s enhanced NDC as they relate to agriculture emissions are summarised here.

Kenya

  • Kenya’s enhanced NDC communicates an economy wide emission reduction target relative to BAU in 2030 of at least 32%. 
  • Key policies for agriculture emission reductions include the National Livestock Policy 2015, the Agriculture Sector Transformation and Growth Strategy (ASTGS) (2019 – 2029), the Kenya Climate Smart Agriculture Strategy (2017 – 2028) among others.
  • Mitigation measures for Agriculture Sector emissions will be achieved by Climate Smart Agriculture (CSA) in line with Kenya’s CSA Strategy, “with emphasis to efficient livestock management systems”.
  • Kenya’s adaptation measures include using CSA practices to increase livestock system efficiencies and to build resilience of agriculture systems through sustainable land management.

Ethiopia

  • The BAU analysis is based on a newly adopted Tier 2 inventory for livestock GHG emissions and livestock are projected to be the biggest single emission source in 2030 in the BAU scenario
  • Ethiopia’s economy wide emissions reduction target relative to BAU in 2030 is 12.4% unconditional and a further 41.1% conditional on international support to a total reduction of 53.5%.
  • Of the total livestock emission reductions will contribute 30.4 MtCO2e or 13.8% of the total 220.59 MtCO2e required by 2030 across all sectors.
  • Mitigation measures will be achieved predominantly as improvements to agriculture production efficiencies and changes to agricultural practices.

Rwanda

  • Rwanda’s economy wide emission reduction target relative to BAU in 2030 is 16% unconditional (1.9 MtCO2e) and a further 22% (2.7 MtCO2e) conditional on international support, to a combined total of 38% as shown in figure 1.
  • Agriculture contributes 55% of Rwanda’s total emissions. The largest sources of emissions are methane from enteric fermentation in cattle systems, N2O emissions from managed soils and emissions from manure management.
  • Rwanda’s agriculture mitigation measures will contribute 2.24 MtCO2e (figure 1) in 2030 and include a number of soil conservation practices, compost production and livestock measures.
  • Adaptation measures for agriculture include developing and promoting climate resilient crops and livestock, adopting best crop management practices and developing sustainable land use management practices.
  • Rwanda’s NDC is aligned with several existing national policies including the Green Growth and Climate Resilient Strategy (GGCRS) (2011).

Zambia

  • Zambia’s economy wide emissions reduction target relative to 2010 emission levels is 25% unconditional (20 MtCO2e) and a further 22% conditional on international support to a total reduction of 47% (38 MtCO2e) in 2030.
  • Zambia’s major mitigation measures for agriculture are i) conservation and sustainable agriculture and ii) improving agriculture production efficiencies.

Senegal

  • Senegal’s economy wide emission reduction target relative to BAU in 2030 is 7% unconditional and a further 22% conditional on international support to a total reduction of 29%. This equates to unconditional emission reductions of 2.66 MtCO2e and a total of 11.2 MtCO2e in the conditional target.
  • Agriculture emissions accounted for about 44% of Senegal’s total emissions in 2010.
  • The emission reduction targets for agriculture are 0.25 MtCO2e in the unconditional and 1.27 MtCO2e in the conditional scenario.
  • Agriculture mitigation measures are aligned with the Program to Relaunch and Accelerate the Cadence of Senegalese Agriculture (PRACAS2, 2019-2023) and the Livestock Development Policy (2017-2021)
  • Mitigation measures include assisted natural regeneration, composting, biogas and implementing the system of rice intensification (SRI)
  • Several adaptation measures are listed, including sustainable land management, agroforestry and use of early warning systems and climate information services.

On 3-4 December 2020, the French Agricultural Research Center for International Development (CIRAD) and the CLAND Convergence Institute organized, with the support of the Global Research Alliance on Agricultural Greenhouse Gases (GRA) and the 4 per 1000 Initiative, a virtual workshop entitled “Can albedo change offset the climate benefit of carbon sequestrating practices?“. The overall objective was to discuss the relevance of current carbon-centered accounting systems to assess climate change mitigation potentials of land use change and management.

This workshop gathered twelve top keynote speakers to provide the most up-to-date knowledge about the potential offset or enhancement of the climate benefit of carbon sequestrating practices, identify knowledge gaps and propose a way forward for future research projects.

This virtual event gathered more than 300 participants, from 52 countries and 156 different institutes. Most of the participants (89%) were from universities and research centers, 60% were from Europe, 17% from Asia, and 14% from North America.

All presentations were recorded and available in replay here:

The climate benefit of best management practices is often quantified through the change in biochemical effects, i.e., soil organic carbon (SOC) stocks and greenhouse gases (GHGs) emissions. However, biochemical effects do not stand alone. Planting trees, covering the soil, reducing tillage, adding organic amendments (compost, biochar…), etc, also modify biophysical effects, for example, albedo.

Surface albedo is the fraction of incident solar radiation that is reflected back to the atmosphere, measured on a scale from 0 (100% absorption, 0% reflection) to 1 (0% absorption, 100% reflection). A modification in surface albedo affects top-of-atmosphere albedo and thus the amount of solar energy absorbed by Earth.

It is now well documented that afforestation of boreal regions would have no climate benefit given the negative radiative forcing due to reduced atmospheric CO2 concentration by carbon sequestration in trees and soils (biochemical effect) is offset by decreased surface albedo (biophysical effect) leading to warming and a positive radiative forcing.

However, comparing biochemical and biophysical effects is not straightforward. There are differences in the spatial extent of the two forcings. CO2 is well-mixed in Earth’s atmosphere thus imposing a spatially homogeneous forcing while a change in surface albedo is more localized.

A lot of progress has been made to compare these effects, but metrics still need to be improved. The first day of the workshop was mainly focused on methodological aspects related to quantifying and comparing these effects, as well as on techniques to measure albedo from field studies to remote sensing. During the second day, keynote speakers presented different studies comparing biochemical and biophysical effects for different practices such as cover crops, chlorophyll-deficient crops, biochar, bioenergy crops and forest management.

It was concluded that biophysical effects are significant and failing to account for example for surface albedo can result in suboptimal or even counterproductive climate-motivated policies of the land-based sectors.

The climate benefit of biochar is for example largely reduced when albedo is considered. In contrast, cover crops in Central and West Europe as a general rule of thumb have been shown to increase SOC, reduce GHGs, and increase albedo, potentially a win-win-win strategy.

However, the effect of a given practice on climate is highly context-specific and could have undesirable effects depending on soil type and climate. More field data to explore a diversity of pedoclimatic contexts combined with a diversity of land use and management is required.

Biophysical effects are also very important contributing factors to mitigate local temperature extremes and can play a role in adaptation to climate change. At present, the description of management practices is too coarse in climate models and a better coupling these with soil-crop models could improve the assessment of practices on local, regional and global climate.

Albedo is not the only biophysical effect to consider. The change in the energy balance also has implications for the water cycle, especially for evapotranspiration. For example, forests have a lower albedo than crops or grasslands (warming effect), but a much higher evapotranspiration (cooling effect). Other aspects to consider are changes in surface roughness and emission of volatile organic compounds, affecting turbulent fluxes and the water cycle.

The role of biophysical effects such as albedo on climate change, in relation to management practices, has been scarcely studied, especially for non-forested ecosystems such as croplands and grasslands. The relationship between the two is a crucial information gap that must be filled in the coming decade by the scientific community.
