Ex Ante Carbon Balance Tool For Value Chains

The Ex-Ante Carbon-balance Tool for Value Chains (EX-ACT VC) is a quantitative multi-appraisal tool that evaluates the sustainability of agrifood value chains simultaneously along several environmental, economic, and social dimensions. It analyses greenhouse gas (GHG) emissions along an agrifood value chain, from farm-gate-to-shelf, including GHG fluxes from processing and storage, to packaging and transportation; calculates a set of value-added indicators including gross production value, value-added, and net income; and estimates the number and nature of jobs created along the value chain. It also includes an estimation of food loss at each stage of the value chain; an assessment of gender and youth participation and an SDG tracker. The primary objective of EX-ACT VC is to provide decision support to design (ex-ante) and evaluate (ex-post) agrifood VC projects and policies by comparing a ‘current’ scenario with baseline information and a ‘planned’ scenario involving a future vision or goal (or implemented activities scenario in case of ex-post evaluations). EX-ACT VC helps users to quantify the sustainability performance of the selected value chain, identify the drivers of sustainability, understand how economic, social, and environmental dimensions are intertwined, and identify potential entry points for environmental and socioeconomic improvements along the selected value chain. The EX-ACT VC methodological guidelines aim at: 1) providing a comprehensive overview of the tool and helping users assess the sustainability of agrifood value chains across environmental, economic, and social dimensions using the tool; 2) describing the various methodological concepts underlying the tool to perform a value chain assessment and calculating several indicators of sustainability; 3) illustrating the structural layout of the tool, explaining data requirements, and providing step-by-step data entry guidance to perform a value chain assessment using EX-ACT VC; 4) discussing the different indicators the tool calculates and how they can be used for project and policy evaluation and design. These guidelines are intended to assist potential users of EX-ACT VC including policymakers, project managers, analysts, and researchers, among others.

Complementing the longer EX-ACT User Manual, this guide provides an overview of the Ex-Ante Carbon-balance Tool, a land-based accounting system that prioritizes project activities with the greatest economic benefits and potential for climate change mitigation.

This practical guidance presents details on how to use the EX-Ante Carbon-balance Tool for Value Chain (EX-ACT VC), with the aim of providing a multi-impact appraisal in terms of socio-economic and environmental assessment for value chain analysis. Following the EX-ACT logic, EX-ACT VC compares the environmental and socio-economic performances of current value chains with those of an improved scenario (applicable to different degrees of the chain), based on the analysis of agricultural production, land use changes, processing, transport and climate resilience. EX-ACT VC has been developed for all types of agricultural sectors (which include here fisheries and livestock) that have the potential to mitigate the effects of climate change and to develop the resilience of rural populations that are dependent on them. The tool targets value chains in developing countries for single or more complex sectors, taking into account several agricultural practices and one end-type specific to a region or area.

Preliminary assessments of the cocoa value chain from using FAO's EX-ACT Value Chain tool show that it has a significant potential to improve farmer incomes while mitigating climate change. With a renovation and rehabilitation strategy of implementing cocoa shadow agroforestry in low-yielding old plantation areas, the mitigation impact of the value chain reaches approximately 146 million tCO2e in the next 20 years. This translates to a carbon footprint of – 5.6 tCO2e for every tonne of cocoa produced. Additionally, the gross income per farmer increases by almost 38 percent - up to USD 10.46 per working day by 2028. Most of the value-added coming from the upgraded scenario stems can be attributed to the producer – more than USD 1 billion in an aggregate value added of over USD 1.6 billion by 2028. Moreover, the cocoa value chain will create an additional 277 669 jobs, and increase the climate resiliency of almost 1.85 million hectares of landscape in Ghana.

Based on past experience of partnership on support to National Rice Development Strategies (NRDS) within Coalition for African Rice Development (CARD), AfricaRice and FAO decided to conduct a series of rice policy reviews for Ghana, Ivory Coast and Mali in 2019. The following study uses the Ex-ante Carbon-balance Value Chain tool (EX-ACT VC), developed in 2016 by FAO, to assess the Ghanaian rice value chain’s environmental (in terms of climate mitigation and climate resilience) and socio-economic impact for a business as usual scenario in 2020 compared to a growth scenario for 2030. Promotion of good agricultural practices (GAP), the reduction of crop losses, and an increase in the use of inputs and mechanization are the different strategies considered in this study that would help in realizing the aim of self-sufficiency.Through the implementation of these practices, along with the expansion of rice growing areas, the income per day of work per farmer would increase by more than USD 4, reaching approx. USD 9/day of work in the value chain. The gross production value of the rice value chain would reach USD 856 million, which is an additional USD 511 million in gross production value by 2030. An upgraded rice value chain would also result in an increase in the value added by USD 378 million by 2030 with an overall positive carbon balance that would emit 284 852 tCO2-e of greenhouse gas emissions.

The present technical study provides the results and a summary of the most important lessons learned from implementation of a series of climate-smart agriculture (CSA) practices in the rice supply chains of Gagnoa in Côte d’Ivoire. The aim of the CSA practices was to enhance the adaptive capacity of the rice sector against climate change, as erratic rainfall patterns and droughts events have, historically, significantly impacted production. This study relies on data collected at farm and processing levels during two field missions to two pilot sites in August 2017 and September 2018 under the project “Contribution à l’atteinte des objectifs liés au changement climatique et à la sécurité alimentaire via l’agriculture intelligente face au climat en Côte d’Ivoire – cas de la filière riz”. This project is a technical cooperation project implemented by the Food and Agriculture Organization of the United Nations (FAO) from 2016 and 2018. The study provides a series of recommendations for policymakers, including incentives for the development of a modern bioenergy sector in Côte d’Ivoire which are still nascent.

As part of its Sustainability Program, the Global Shea Alliance (GSA), in partnership with the Food and Agriculture Organisation of the United Nations (FAO Regional Office for Africa), conducted this multi-impact appraisal of the shea value chain in 8 West African countries that account for 99% of shea exports. The study uses the EX-ACT Value Chain tool (EX-ACT VC), developed in 2016 by the FAO, to assess the value chain’s contribution to climate mitigation, climate resilience, and socio-economic impact. At present, the shea value chain fixes 1.5 million tons of CO2 every year. Relative to production volumes, every ton of shea kernels produced has a negative carbon footprint of 1.04 tons of CO2. With an expansion strategy supported by donors and private partners to increase shea tree population in agroforestry areas by 7 million additional trees per year, the CO2 fixed could increase up to 9 million tons of CO2e per year, leading to an aggregated carbon fixing impact of 180 million tons of CO2e over 20 years. Through shea parklands expansion and improvement of collector productivity, the gross income per woman collector could increase to US$ 167/ year, while the value added per day of work will reach US$ 2.30. The global value chain will reach a gross production value of about US$ 593 million, representing 6% growth per year between 2019 and 2032 and a value added of US$ 452 million by 2032.
