Editor's Notes
- Good morning, or afternoon and welcome to the first session of the 2019 CLIFF-GRADS webinar series
- Abubakar Hailu Girei is a PhD student at Ahmadu Bello University in Nigeria where he is studying the greenhouse gas implications of rice intensification and fertilizer management practices. He also works in the Department of Soil Science, Federal University Dutse, Nigeria. His CLIFF-GRADS fellowship was at the International Center for Tropical Agriculture in Colombia. Ridha Ibidhi is a PhD student at the Mediterranean Institute for Agricultural Economics of Zaragoza and works at the National Institute of Agriculture Research, Tunisia. His research focuses on environmental indicators of livestock production systems. As a CLIFF-GRADS fellow he was hosted by Bangor University in the UK. Sebastián Vangeli is a PhD fellow at the National Institute of Agricultural Technology and a PhD student at Buenos Aires University, both in Argentina. His PhD research is focused on the impact of agricultural management practices on nitrous oxide emissions. As a CLIFF-GRADS fellow he was hosted by Rothamsted Research and Bangor University in the UK. Yohannes Gelan Regassa is a PhD student in agronomy at Bahirdar University with a focus on climate variability and change and its impact on dryland agriculture. He is also a senior lecturer and researcher at Kombolcha Agriculture College, Wollo University. He was a CLIFF-GRADS fellow at Wageningen University in the Netherlands.
- Over its 9th replenishment period (2011-2014), IFAD invested approximately US$5.6 billion in 189 projects to improve productivity, market participation and climate resilience. Using 90 project design documents, we identified projects that supported implementation or scale-out of improved agricultural practices that are also found in the Climate-Smart Agriculture Compendium as defined in Table 1. The agricultural practices most commonly included in IFAD investments were irrigation and water harvesting, followed by reduced tillage, agroforestry, increased crop diversity, and organic fertilizers (Table 3).
- In order to estimate the total mitigation potential of IFAD investments in improved agricultural practices, we assumed that each farmer targeted for a particular project intervention adopted the improved practice on 0.5 ha of land, based on recent estimates that 72% of farms worldwide are less than 1 ha (Lowder et al. 2016). We further assumed that practices would be maintained indefinitely without dis-adoption and that all the farmers and hectares targeted for adoption were unique (e.g. none of the farmers adopting agroforestry were the same farmers also adopting organic fertilizer). These assumptions are part of the reason why our findings represent an upper bound. Using the global mean mitigation potentials calculated in this analysis, we estimated a total annual mitigation potential for field-level practices within the IFAD9 portfolio of 738,000 – 1,740,000 t CO2e year-1. The lower and upper bounds reflect the 95% confidence intervals of the mitigation potentials. This is approximately equivalent to removing 158,000 – 372,500 passenger vehicles from the road for one year. However, one of the flaws of this study was that we did not have the data necessary to analyze the investments in livestock value chains, which is where you might see either large increases in emissions or substantial mitigation potential.
- The second case I’m going to discuss is an analysis that was led by Julie Nash, who is a former Gundee, while she was working with CCAFS CCAFS, working with FAO, examined the mitigation co-benefits of USAID’s agricultural investment portfolio. (was this against current emissions or a future baseline?) This figure shows the USAID analysis, for 25 diverse agricultural development projects and several dozens of practices across 15 countries in 3 continents. You can see that across the entire portfolio,blue is negative emissions, yellow is positive, that ag investments resulted in substantial net mitigation co-benefits, 2.6 MtCO2e/yr. Looking at interventions across categories you can see that the major source of emissions was livestock and secondarily fertilizer use, but that this was offset by land use change and rice and crop management. So current trajectories of agricultural development can yield substantial mitigation co-benefits, especially when considered at the larger portfolio level. That is the good news… ****** Landscape and crop transitions 1) Landscape transitions- Within the agricultural development projects, project interventions focused on both avoided land conversion (avoided change from forest) and active land conversion (agricultural or degraded lands changed to forest). 2) Crop transitions- This area include transitions to perennial crops or agroforestry. Also transitions from flooded rice systems to other crops such as wheat. Transitions land into irrigated rice. (Check why 5802 in positive) Management practice improvements 1) Rice crops- AWD, UDP, Short Duration Rice 2) Crops- Soil, manure, and water management improvements- also includes crop residue burning reduction and perennial management. 3) Fertilizer- increases and decreases 4) Livestock- herd size management, feed quality and breeding improvements. Grassland increases. With better feeding practices and increases in cow weight comes increased emissions.
