NAMA Seeking Support for Implementation

  • A Overview
    • A.1Party
      A.2Title of Mitigation Action
      A.3Description of mitigation action

      Costa Rica Rice NAMA aims to achieve a transformational change in the value chain of rice cultivation, industrialization, marketing and profitable management with a climate focus.

      The rice sector contributes significantly to the country's GHG emissions. According to the most recent National Emissions Inventory, rice cultivation emitted 218.6 Gg of CO2eq in 2017, a value that corresponds to more than 7% of total CO2eq emissions from the agricultural sector, and 1.5% of total CO2eq emissions of the country (without taking into account the forestry sector and other land uses). In this sense, the inclusion of the Rice NAMA in the national decarbonization goals is especially important.

      To achieve a transformation of the sector towards low-carbon production, three key measures with the greatest potential for reducing emissions were selected: (i) changes in water regimes; (ii) fertilization practices that reduce emissions; and (iii) use of adapted rice varieties.

      E.1.2Comments on full cost of implementation

      The total cost to implement the NAMA comes from the resources required to finance low-carbon production (USD 8.35M during the pilot plan and USD 25.06 during the scaling up). It also covers the resources necessary to implement the enabling actions of the NAMA (USD 0.82M during the pilot plan and USD5.43 during the scaling up).

      To encourage producers to apply low-carbon measures, soft financing must be enabled, which is not yet available given that banks only finance 0.5% of national production. The rice NAMA proposes that 50% of the resources to finance low-carbon production come from producers, industry and commercial enterprises. It is suggested that the remaining 50% (USD 16.7M) be managed by CONARROZ as reimbursable funds through the Bank for Sustainable Development of Costa Rica, multilateral-bilateral banks, or competitive funds.

      Financing for low-carbon production is defined as the resources necessary to finance mitigation measures, inputs and services to achieve the desired production. These needs were calculated from an analysis of anual rice production cash flows and working capital. The financing of the enabling actions allows aligning the current operations of CONARROZ and the public-private sector towards mitigation actions in the rice sector. These NAMA enabling actions are summarized in the following categories: 1) Disclosure and communication to the producer/processor and consumer awareness campaigns; 2) Specific decarbonization actions in pilot farms; 3) Research, Innovation and Development; 4) Technical services; 5) Strengthening of CONARROZ; 6) Marketing and certification actions; 7) Monitoring, Reporting and Verification; 8) and Administration and Finance.

  • G Estimated emission reductions
    • G.1Amount
      G.3Additional imformation (e.g. if available, information on the methodological approach followed)

      The value is estimated according to the following parameters: national intervened area, percentage of the national intervened area, harvested area growth rate, participation of rice systems (irrigated and rainfed), rate of increase of national production yield, national production yield, emission intensity indicator versus production, water regime prior to planting and water regime during cultivation.

      This value (F.1) corresponds to the emissions scenario of the NAMA Rice conceptual pilot (scenario 1). In this scenario, the GHG emission reduction intervention is modeled in 10 small, 7 medium and 3 large producers. The parameter values are:

      - National intervened area: Annual average of 3,803 hectares.

      - Intervened area within the national rice area: 8.7%.

      - Growth rate of the harvested area: 4% per year compared to the official data for 2019.

      - Participation of rice irrigation systems: 46%.

      - Participation of rainfed rice systems: 54%.

      - National production yield increase rate: 1% per year based on the year 2019.

      - National yield: 4.5 tons per hectare. This is the performance achieved in 2030.

      - Indicator of intensity of emissions versus production: 1.9 tCO2-eq per-ton produced.

      - Water regime prior to sowing: It is not flooded less than 180 days after sowing.

      - Water regime during cultivation: For irrigated rice, multiple drainage periods are contemplated and regularly fed by rains for dry land.

      The report also provides two other emission scenarios: E2 - Conservative rice annual growth with gradual transition to irrigated rice systems and E3 - Sustainable modernization of rice production systems. The values of the parameters and their emission reductions are detailed in said report. Scenario 1 is mentioned in this application, as it is the one determined to be the most plausible according to industry experts.

  • H Other indicators
    • H.1Other indicators of implementation

      • Number of farms implementing NAMA Rice measures.

      • Reduced emissions (Ton CO2e) compared to BAU in NAMA farms, differentiating by

      o Farm in Rainfed

      o Farm under irrigation

      • Intensity of emissions (Kg CO2e/Kg of paddy rice) for NAMA farms with irrigation and rainfed

  • I Other relevant information
    • I.1Other relevant information including co-benefits for local sustainable development

      It is considered that in addition to the reduction of GHG emissions, co-benefits of productivity, profitability and climate resilience would be achieved.

      These co-benefits are given thanks to the actions implemented by the rice NAMA such as: training for producers through agronomic management manuals and training programs in different areas of the sector (for example, the most efficient use of water and fertilizers) ; promote the optimized use of improved varieties, prioritizing their adaptability to local conditions; favoring the association of farmers, strengthening the local and national network of farmers; implementation of production records for small and medium famers; economic support to young farmers in entrepreneurship programs in the rice activity; promotion of alliances between institutions for a better training network and support for farmers, strengthening the rice sector in general.

      Costa Rica has an important history of ambition and climate action, and it is a nation that has several international treaties related to environmental challenges of interest to both the world community and the country. Costa Rica has been part of the Paris Agreement since 2016 and presented its first NDC in 2015, updating it in 2020.

      In coordination with international commitments, the country has adopted a series of policy designs linked to the promotion of productive activities (including rice) that are sustainable and friendly to the environment and, especially, that reduce GHG emissions , thereby allowing it to get closer to its climate ambitions.
