    Using Marginal Abatement Cost Curves to Realize the Economic Appraisal of Climate Smart Agriculture Policy Options

    The AFOLU sector (Agriculture, Forestry, Land Use) is directly linked with climate change issues, on an environmental aspect as well as on an economical and social aspect (food security). Yet, while there is a wide range of technical solutions, it is not immediately apparent which options deliver the most economically efficient reductions in GHG within agriculture. This is why methodologies such as a Marginal Abatement Cost Curves (MACC) have been developed over these past twenty years. MACC als o enables the comparison of the cost-effectiveness of mitigation options between different sectors (e.g. agriculture, power, transport, industry and domestic energy consumption). MACC has become a useful tool for policy makers to prioritize mitigation options. This paper aims at putting forward a methodology to use MAC-curves within the AFOLU sector. It especially targets policy planners and policy makers. The agricultural sector, also called agriculture or AFOLU, encompasses farm-based activiti es (crop production, livestock) as well as forestry and land use. It does not include the downstream agro-industry sector. The first part of these guidelines explains the methodology in order to assess the cost-effectiveness and the mitigation potential of technical practices in agriculture. It also underlines the limits of the MACC approach. The second part looks at a practical MACC analysis example, using the EX-ACT tool.

    The Carbon Balance of the World Bank-financed Land Husbandry, Water Harvesting and Hillside Irrigation (LWH) Project of the Government of Rwanda: Application of the EX-Ante Carbon-balance tool (EX-ACT)

    Agriculture can play an important role in climate change mitigation while contributing to increased food security and reductions in rural poverty. The Ex-Ante Carbon-balance Tool (EX-ACT) can estimate the mitigation potential of rural development projects generated from changes in farming systems and land use. The study presents and discusses the EX-ACT analysis performed on the World Bankfinanced Land Husbandry, Water Harvesting and Hillside Irrigation Project of the Government of Rwanda. Estim ates of the impact of project activities on greenhouse gas emissions and carbon sequestration demonstrate that the implementation of the LWH project will provide additional environmental benefits by helping to mitigate climate change. Thus it reflects possible synergies between mitigation and rural development goals through a watershed approach.

    Mangrove carbon estimator and monitoring guide 2016
    Also available in:

    Mangroves exist in the inter-tidal zone of sheltered tropical and subtropical coasts, and in Southeast Asia are home to 42 tree and shrub species found nowhere else (Giesen et al. 2006). These ‘true mangrove species’ and other associate species are adapted to marine and brackish conditions, and are capable of sequestering and storing large amounts of atmospheric carbon dioxide. This guide outlines a simple, low-cost methodology for measuring mangrove carbon stocks and monitoring mangroves in def ined project areas. The methodology for measuring mangrove carbon stocks was designed in collaboration with Yale University and was published in PLOS ONE journal in January 2017<.i>. This is the third in a series of four publications intended to be used in conjunction in establishing sustainable financing for mangrove protection in Asia. The titles and links of the four publications are as follows: :
