15、troductionIntroductionIn the past few years,the global economy has been lashed by the COVID-19 pandemic,geopolitical conflict,supply chain disruptions,an energy crisis,and high inflation.These challenges are occurring against the backdrop of the mounting planetary emergency of climate change.Climate

16、 change can exacerbate all other challenges;increasing geopo-litical conflicts over resources,crippling infrastructure and supply chains,extending the range of dangerous pathogens,and causing the collapse of the natural systems upon which we depend.As the US Pentagon presciently stated:“climate chan

17、ge is a threat multiplier”.While the transition to a sustainable,net-zero future is critical,it demands fundamental shifts in nearly all economic sectors.These shifts are not without risk for companies and the communities impacted by them.Financial institutions face an array of risks from this rapid

18、ly changing,and often chaotic,global context.Their clients are exposed to physical hazards as well as transition risks.These can have major credit,market,and operational implications.The prudent financial institution will explore these climate-related risks and prepare strategies to meet them.Ensuri

19、ng resiliency and success in the future depends on making good decisions and thoughtful plans today.UNEP FI has been working at the intersection of sustainability and finance for over 30 years.Its programmes for financial institutions develop the tools and practices neces-sary to positively address

20、the most pressing environmental challenges of our time.UNEP FIs Climate Risk and TCFD programme has now worked with over 100 financial insti-tutions to explore physical and transition risks posed by climate change.Through this work,a need has been identified to provide financial institutions with a

21、baseline under-standing of climate-related risks and their manifestations across different sectors.This brief is part of a series of notes that cover major economic sectors and their asso-ciated climate risks.UNEP FI intends for the resources and perspectives included within these notes to empower f

22、inancial colleagues to communicate these risks throughout their institutions and across the financial sector more generally.The hope is that the communication process will not only enhance awareness of climate risks,but also begin conversations that will lead to tangible changes in strategy and oper

23、ations.The extent to which these insights are integrated will be the truest test of this series effectiveness.This particular brief covers the physical and transition risks facing the agriculture sector.Sectoral Risk Briefings:Insights for Financial Institutions|Climate Risks in the Agriculture Sect

24、or 7Contents|Agriculture overviewAgriculture overviewEmissions produced from the agriculture sector are driving the global temperature to rise at an alarming rate.The Food and Agriculture Organization(FAO)of the United Nations reported that emissions from agriculture and related land use account for

25、 17%of global greenhouse gas(GHG)emissions(FAO,2018).Agricultural activities and food production are associated with carbon dioxide(CO2),nitrous oxide(N2O),and methane(CH4)emissions.Direct emissions from the sector are typically N2O and CH4(Lynch et al.,2021).Around one third of global methane emiss

26、ions(32%)come from cows and other livestock due to the fermentation process during digestion.Methane emissions are also released during other agricultural activities,such as manure decomposition and rice cultivation(UN,2022).Nitrogen fertilizers cause N20 emissions due to the excess amounts of nitro

27、gen that they release in agricultural runoff(UN,2022).The agriculture sector is also one of the main drivers of CO2 emissions caused by land-use change,such as clearing land for crop production.Land use-related CO2 emissions account for about 14%of annual CO2 emissions.Of this 14%,the majority(71%)a

28、re directly linked to agriculture(Lynch et al.,2021).The global food system is also the primary driver of biodiversity loss,with agriculture threatening 24,000 of the 28,000 species at risk of extinction(UNEP,2021).Figure 1:Emissions from agricultural activities and the share of agriculture in globa

29、l GHG emissions(FAO,2020)Sectoral Risk Briefings:Insights for Financial Institutions|Climate Risks in the Agriculture Sector 8Contents|Agriculture overviewIn spite of the fertilizer effect of CO2,higher temperatures will push many regions past optimal growing temperatures and yields.According to est

30、imates by the United Nations,the global population is expected to rise to about 10 billion by 2050(United Nations,2021),which will add pressure on already strained food systems.As rainfall and weather patterns increasingly shift,crops may be damaged by the severe climate events result-ing from these

31、 changes,such as floods,storms,and droughts(Colombia,2022).If global warming worsens,rising global temperatures and extreme weather events threaten to significantly affect agriculture production.According to the Globagri-WRR model,a global agriculture and land-use accounting system,agricultural land

32、 use will need to expand by over three billion hectares in order to meet the projected land demand for 2050.This massive increase in land use will result in major increases in GHG emis-sions(World Bank,2020).As economies set climate targets,decarbonisation of the agriculture sector poses significant

33、 transition risks.Below,we explore in depth the key physical and transition risks faced by the agriculture(including aquaculture)sector(Table 1).Table 1:Key climate risks for the agriculture(including aquaculture)sectorRiskSummaryTransition RisksIncreasing carbon priceImplementing carbon taxes could

34、 greatly impact the production and operating costs of carbon-intensive agriculture activities.Public policy restrictionsGovernments can increase policy pressure through policies related to pasture reduction,deforestation,and oil palm expansion.Advancements in less carbon-intensive technologyTraditio

35、nal agricultural producers can face pressure from producers that adopt the use of less carbon-intensive technologies.Shift in market preferencesDue to rising awareness of the large carbon footprint of the sector,consumers are increasingly willing to change eating habits and shift to other alternativ

36、es.Growing investor actionDue to the growing consideration of climate risks,investors are calling on countries and companies to reduce emissions produced from the sector.Rising reputational riskCompanies linked to agricultural activities that drive climate change,such as deforestation,are increasing

39、ity of crops and livestock.Sea level riseSea level rises can impact biodiversity,decrease soil quality,induce more flooding,and increase saltwater intrusion and soil salinisation,causing production to fall and negatively impacting income and food security.WildfiresIncreased severity and frequency of

42、,fisheries,and livestock,contribute to a fifth of GHG emissions.In order to achieve net zero by 2050,the sector needs to reduce emissions(FAO,n.d.).As a result,the agriculture sector is exposed to multiple transition risks,including policies and regulations,technological shifts,and changes in consum

43、er preferences.The transition risks facing the agriculture sector also pose a risk for workers and communities that rely on the the sector for jobs and income.It is therefore important to align financing with a just transition approach that considers the impact of the transition on groups at risk to

45、sions.As policymakers and decision makers try to curb carbon emissions,the agriculture sector faces increasing risks from the implementation of carbon prices worldwide.In 2021,global carbon pricing reve-nue rose by 60%as compared to 2020,reaching approximately US$84 billion.Carbon prices are reachin

46、g record heights in markets such as the European Union(EU),Califor-nia,New Zealand,Korea,Switzerland,and Canada(World Bank,2022).The Organisation for Economic Co-operation and Development(OECD)projected that a carbon price of US$240 per ton of CO2 equivalent emissions by 2050 would be consistent wit

47、h a 1.5 climate target.Such a price point would serve to reduce net agriculture,forestry,and other land use(AFOLU)emissions by the 129%required to achieve the target,the OECD calculated(Ben Henderson et al.,2021).Implementing carbon taxes could greatly impact the production and operating costs of ca

48、rbon-intensive agriculture activities(Schnitkey,Zulauf&Paulson,2021).Research suggests that,on average,a carbon tax of US$144 per ton of CO2 equivalent emissions could increase production costs for energy-intensive crops,such as corn and soya beans,by 27.45%.Increased production costs can be partial

49、ly compensated through increased commodity prices.For example,a carbon tax of US$144 per ton can decrease returns for maize and wheat by 11.4%and 11%,respectively.Increased production costs of crops due to carbon taxes can cause a shift in production and trade patterns,poten-tially precipitating a r

50、eallocation of land use globally.For example,imposing a carbon tax on corn and wheat could increase preference for commodities such as barley,soya beans,and sunflowers by 1.2 to 8.8%(Dumortier and Elobeid,2021).Carbon taxes also have a negative impact on the income of farmers.British Columbia introd
