REDD policies
  • Climate mitigation (Climate)
The objective of REDD policies it to reduce land-use related emissions by protecting existing forests in the world; The implementation of REDD includes also costs of policies. Agricultural economy
Changes in crop and livestock production systems
    General changes in crop and livestock production systems, e.g. more efficient production methods to create higher production per unit of input, or other systems like organic farming Agricultural economy
    Agricultural trade policies
    • Agricultural land use (Land use)
    • Trade (Food)
    Changes in agricultural trade policies are applied to the corresponding quota (export or import quota) or border taxes. Agricultural economy
    Reduction of waste/losses
    • Agricultural land use (Land use)
    • Food demand (Food)
    Reduction of losses in the agro-food chain and waste after consumption. Agricultural economy
    Changes in consumption and diet preferences
    • Agricultural land use (Land use)
    • Nutrition and diet (Food)
    • GHG emissions (Climate)
    • Animal husbandry (Food)
    • Crop production (Food)
    • Food demand (Food)
    Interventions that target consumption changes or changes in dietary preferences Agricultural economy
    Closing the yield gap
      This intervention increases actual yields (reduces the gap between potential and actual yields), usually realized by better management. Agricultural economy
      Implementation of biofuel targets
      • Energy system (Energy)
      • Other energy (Energy)
      • Energy demand (Energy)
      • Agricultural land use (Land use)
      • Eco goods and services (NB)
      • Land cover (NB)
      • Other nature and biodiversity (NB)
      • Climate mitigation (Climate)
      Policies to enhance the use of biofuels, especially in the transport sector. In the Agricultural economy component only 'first generation' crops are taken into account. The policy is implemented as a budget-neutral policy from government perspective, e.g. a subsidy is implemented to achieve a certain share of biofuels in fuel production and an end-user tax is applied to counterfinance the implemented subsidy. Agricultural economy
      Hydropower
      • Other energy (Energy)
      Construction of dams and reservoirs in rivers Aquatic biodiversity
      Climate change adaptation
        Adaptation to climate change reduces climate damage. The model can optimally calculate the optimal adaptation level based on marginal adaptation costs and marginal avoided damage, but an alternative adaptation level can be used as well. Climate policy
        Effort- or burden-sharing of emission reductions
          Evaluation of burden-sharing or effort-sharing regimes. Which regions or countries should contribute, when and by how much to reduce global greenhouse gas emissions? Climate policy
          Emission trading policy
            Analysis of the effect of rules for trading emission credits on regional abatement costs. Climate policy
            Carbon tax
              A tax on carbon leads to higher prices for carbon intensive fuels (such as fossil fuels), making low-carbon alternatives more attractive. Energy conversion, Energy demand, Climate policy
              Reduction proposals (pledges)
                Evaluation of current reduction proposals by countries and policy options (for the next 10-20 years). Climate policy
                Financing climate policy
                • Other climate (Climate)
                Developed countries could provide financial resources to assist developing countries by implementation of mitigation and adaptation policies. To mobilise these funds, several mechanisms exist, of which the effect can be analysed Climate policy

                      It is possible to prescribe the shares of renewables, CCS technology, nuclear power and other forms of generation capacity. This measure influences the amount of capacity installed of the technology chosen. Energy conversion
                      Improving energy efficiency
                        Exogenously set improvement in efficiency. Such improvements can be introduced for the submodels that focus on particular technologies, for example, in transport, heavy industry and households submodels. Energy demand
                        Subsidies on modern energy
                          Reduces the costs of modern energy to reduce traditional energy use (can be targeted to low income groups). Energy demand
                          Provision on improved stoves for traditional bio-energy
                            Increases the efficiency of bio-energy use. Energy demand

                                  • Terrestrial biodiversity (NB)
                                  Increase the use of wood from highly productive wood plantations instead of wood from (semi-) natural forests. Forest management
                                  Expanding Reduced Impact Logging
                                  • Forestry (Land use)
                                  Increasing the share of produced wood yielded with Reduced Impact Logging (RIL) practices instead of conventional logging practices. Forest management
                                  More sustainable forest management
                                    Sustainable forest management aims for maintaining long-term harvest potential and good ecological status of forests (e.g. the nutrient balance and biodiversity). This can be implemented by (i) enlarging the return period when a forest can be harvested again; (ii) only using certain fractions of the harvested biomass and leave the remaining part in the forests. Forest management

                                            Change in grazing intensity, usually more intensive. This would require better management of grasslands, including for example the use of grass-clover mixtures and fertilisers, bringing the length of the grazing season in tune with the period of grass production, and rotations. Land-use allocation
                                            Intensification/extensification of livestock systems
                                            • Animal husbandry (Food)
                                            A change in the distribution of the production over pastoral and mixed systems; usually to a larger share of the production in mixed systems, which inherently changes the overall feed conversion ratios of ruminants. Livestock systems
                                            Improvement of feed conversion
                                            • Agricultural land use (Land use)
                                            • Animal husbandry (Food)
                                            Improvement of feed conversion ratio of small ruminants, such as sheep and goats. This means other breeds will be used that need less grass to produce the same amount of meat. Livestock systems
                                            Increased livestock productivity
                                            • Agricultural land use (Land use)
                                            • Animal husbandry (Food)
                                            A change in production characteristics, such as milk production per animal, carcass weight and off-take rates, which will also have an impact on the feed conversion ratio; in general, this will be lower in more productive animals Livestock systems
                                            Changes in feed ration
                                              Change in the share of grass in the feed rations of cattle, sheep and goats, usually a decrease, meaning grass will be substituted by feed crops and the livestock system will be more intensive. Livestock systems
                                              Improved manure storage
                                                Improved manure storage systems (ST), considering 20% lower NH3 emissions from animal housing and storage systems. Nutrients

                                                Increase the access to improved sanitation, and connection to sewage systems; institution of wastewater treatment installations; recycling of human waste for substitution of synthetic fertilisers. Nutrients
                                                Integrated manure management
                                                  Better integration of manure in crop production systems. This consists of recycling of manure that under the baseline scenario ends up outside the agricultural system (e.g. manure used as fuel), in crop systems to substitute fertiliser. In addition, there is improved integration of animal manure in crop systems, particularly in industrialised countries. Nutrients
                                                  Increased storage capacity
                                                  • Flood risk (Water)
                                                  • Irrigation (Water)
                                                  Increasing storage capacity assumes that the total water volume stored in large reservoirs will increase. This can either be established by an increase of the capacity of existing reservoirs, or by building new reservoirs. Water
                                                  Improved irrigation efficiency

                                                  • Crop production (Food)
                                                  Improved rainwater management assumes a decrease in the evaporative losses from rainfed agriculture and the creation of small scale reservoirs to harvest rainwater during the wet period and use it during a dryer period. Both measures lead to more efficient use of water and increased yields on rainfed fields. Water
