    Abstract: Reforming agricultural support is increasingly considered a viable means to enhance agriculture’s contribution to climate change mitigation, while fulfilling broader food systems policy objectives related to food security and livelihoods. This study uses a new computable general equilibrium model to investigate a set of global policy reform scenarios that reorientate governments’ budgetary transfers to agriculture to reduce greenhouse gas emissions. The results suggest that removing budgetary support globally would reduce agricultural emissions by 2.1% with potential negative effects on food supply. Reorienting existing support, instead, could have significantly stronger effects: decoupling payments from production and tying these to suitable agri-environmental practices could raise emission reduction to over 4% without harming food supply. Targeted investments in productivity and abatement technologies could bring additional emission savings in the long term with co-benefits for food security. Overall, combining green decoupling and investment policies in OECD countries would reduce global agricultural emissions by 5% – or by 11% if extended to other regions – while balancing outcomes across the three dimensions of the food systems’ triple challenge.

    Parallel Title: Parallele Sprachausgabe Lignes directrices pour l'élaboration d'un indicateur de biodiversité des habitats agricoles propre à l'OCDE
    Keywords: Agriculture and Food ; Environment
    Abstract: With half of the world's habitable land being used for agriculture, monitoring the biodiversity on agricultural land is essential for meeting the objectives of the United Nations Convention on Biological Diversity (CBD). This paper seeks to advance the monitoring of farmland biodiversity in OECD countries by investigating current national initiatives and proposing guidelines for the development of an indicator based on habitat. The proposed approach provides a flexible and pragmatic framework to harmonise reporting from national programmes while accommodating cross-country diversity in contextual factors, including farming systems, climate, biophysical conditions and species pools. To facilitate implementation in the near term, the indicator includes a three-tiered approach to reporting based on data availability, which accommodates countries with limited data resources as well as those that currently have monitoring programmes in place.

    Abstract: Increasing agricultural productivity growth sustainably can help to address the triple challenge of providing sufficient affordable and nutritious food for a growing global population, while supporting sector livelihoods and improving environmental outcomes. However, challenges remain in measuring environmentally sustainable productivity growth. This study uses alternative approaches to address these challenges and provides answers to the following questions: i) has Total Factor Productivity (TFP) growth coincided with improved environmental outcomes?; and ii) has the agricultural productivity and environmental performance of countries improved over time? While there is compelling evidence that TFP growth has helped countries to expand agricultural output and reduce greenhouse gas emissions per unit of output, these emissions increased in absolute terms for about half of the OECD countries assessed and nitrogen surpluses increased for about one-third. While these environmental impacts would have been larger if output had expanded in the absence of productivity growth, there is room to steer innovation in the sector in a more environmentally sustainable direction.

    Abstract: Net soil carbon sequestration on agricultural lands could offset 4% of annual global human-induced GHG emissions over the rest of the century and make an important contribution to meeting the targets of the Paris Agreement. To harness this potential of the agricultural sector to positively contribute to the sustainability agenda, a package of policies is needed to enhance global soil carbon stocks. Such a package would include regulations to prevent the loss of soil carbon, knowledge transfer policies to promote “win-win” solutions, and additional incentives delivered via market-based policies. The latter will need to be supported by innovative contracting solutions to address concerns about the non-permanence of carbon stocks and to reduce transaction costs.

    Abstract: The relationship between agricultural support policies (adapted from the OECD Producer Support Estimate (PSE) classification) and a selection of environmental impacts are analysed in a range of country settings, using a farm-level and a market-level model. Based on the methods and environmental indicators used, market price support and payments based on unconstrained variable input use were the most environmentally harmful among the various PSE measures. Decoupled support payments based on non-current crop area were the least harmful, even when considering their impacts on the behaviour of risk averse farmers. The impacts of support policies that clearly change the competitiveness of one production activity in relation to another, such as payments based on current crop area or on animal numbers, were more equivocal. Support payments subject to environmental constraints can improve environmental outcomes compared to coupled support without restrictions, however, they can also have unintended environmental impacts.

    Abstract: This paper develops theoretical and quantitative analysis to identify the potential synergies and trade-offs inherent in various policy instruments that address agricultural productivity, climate change mitigation and adaptation, and water quality objectives. The theoretical model used describes crop production choices made by farmers given different sets of government policies and whereby crop yields can be impacted by climate change. Quantitative results on the basis of Finnish data show that decoupled area payment appears to provide more trade-offs than other policy instruments as it increases greenhouse gas (GHG) emissions and nutrient runoff, and decrease total factor productivity and social welfare relative to a situation with no policy. Nitrogen fertiliser tax, a soil GHG emission tax, and a subsidy for green set-aside perform well with respect to all other objectives with the exception of adaptation to climate change. These policy instruments significantly reduce GHG emissions and nutrient runoff, and thus their social welfare performance is high.

    Abstract: This report develops quantitative and qualitative frameworks to test the possibility of systematically assessing a range of policies and their intended and unintended effects. The analysis spans the three policy objectives of enhanced productivity, climate change mitigation, and climate change adaptation. The preliminary findings and lessons learned are drawn from two applications of a qualitative framework (France and the Netherlands), where information was gathered through a wide-ranging questionnaire, and from two applications of a quantitative modelling framework which was tested using data from Finland and from selected sites in one region of the United States.

    Abstract: This report assesses the crucial drivers of ecosystem services and proposes actions to develop a more effective policy mix. Several elements form the basis of this report. First, a literature review provides an overview of the state and trends of ecosystem services linked to agriculture, including issues related to land use. Secondly, results are presented from a quantitative model developed to illustrate the potential benefits of improving policy design as well as to investigate synergies and trade-offs among ecosystem services. This report also includes a review of experiences in an inventory of ecosystems in selected countries and policy initiatives that address ecosystem services linked to agriculture.

    Abstract: Biodiversity conservation and sustainable use policies implemented in OECD countries could be made more environmentally effective and cost-effective. Several policy innovations could change this, however. To test this, a theoretical framework was developed to describe farmers’ participation in government payment programmes that enhance semi-natural wildlife habitats on farmland. The types of payments analysed here include: uniform payments; three types of conservation auctions with environmental targeting; uniform payment with environmental targeting; and two types of differentiated payments with environmental targeting. Quantitative results show that uniform payments are less efficient than other payment types, and that auctions with environmental targeting are the most cost-effective option. However, if farmers have knowledge of the environmental value of their offer, the cost-effectiveness of auctions decreases because they tend to increase their bids to benefit from this information rent (overcompensating income forgone). Adding environmental targeting to the uniform payment policy greatly improves the cost-effectiveness of uniform payment. The analysis clearly shows that, when targeted payments are implemented, the gains from environmental targeting are large and exceed the increase in policy-related transaction costs.

    Abstract: This paper investigates farmers’ incentives to participate voluntarily in carbon offset markets when environmental credit stacking is allowed, that is, farmers can stack water quality credits with carbon credits. The implications of stacking on additionality of environmental services in interlinked markets, market participation rates, and market equilibrium prices are analysed by developing a conceptual framework of environmental credit stacking, which is applied with data estimates for the US Corn Belt. Analysis shows that credit stacking increases farmers’ participation in carbon offset markets, and that such increased participation provides additionality in environmental service provision. It is further shown that ecosystem markets are interlinked so that credit price changes in one market will shift credit supply in another market, thus affecting equilibrium prices. Empirical application of the framework shows that provision of CO2-eq offsets through reductions of nitrogen application or through the establishment of green set-asides is not profitable without water quality credits. A conversion from conventional tillage and reduced tillage to no-till is profitable in some cases, although current low carbon offset prices and transaction costs have a significant negative impact on the number of participating parcels. When farmers are allowed to stack water quality credits the profitability of carbon sequestration practices increases. Reduced nitrogen application levels becomes a profitable option and 21% of field parcels - representing 4.6 million acres- participate in the market with water quality credit prices at base levels of USD 3/lb for N and USD 4/lb for P. The establishment of green set-aside and streamside buffer strips becomes profitable in the lower productivity and highly erodible lands with base prices of nutrient credits. If water quality trading markets are small then high participation rates among farmers may result in an oversupply of nutrient credits and as a consequence equilibrium credit prices and farmers’ credit revenue would decrease.

    Abstract: Climate change affects the mean and variability of weather conditions and the frequency of extreme events, which to a great extent determines the variability of production and yields. This paper reviews the scientific literature on the impacts of climate change on yield variance and investigates their implications for the demand of crop insurance and effectiveness of different farm strategies and policy measures using crop farm data in Australia, Canada and Spain. A microeconomic farm level model is calibrated to different types of farms and used to simulate the responses and impacts of four policy measures: ex post disaster payments and three types of crop insurance (individual yields, area-based yield and weather index). The strong uncertainties about climate change are captured in a set of seven scenarios covering different assumptions about the scope of climate change (no change, marginal change, and high occurrence of extreme events), and farmers’ adaptation response (no adaptation, diversification, and structural adaptation). Policy decision making under these uncertainties is analysed using a standard Bayesian probabilistic approach, but also using other criteria that look for robust second best choices (MaxiMin and Satisficing criteria).
