This natural resource challenge is compounded by demographic pressure, weak governance and institutions, and by a deteriorating economic situation. The economic and social outlook is not bright, and planning and international support will certainly be needed to help Yemen to adapt to the further stresses caused by climate change and variability. In the light of these challenges, the government has developed a National Adaptation Program of Action (NAPA). In support of this, the World Bank commissioned a series of studies of climate change in two phases: the first phase projected climate change scenarios for Yemen, and phase two assessed climate change impacts on the agricultural and water sectors, and outlined possible policy and program responses. The present study is essentially a digest of the work done to date, and is intended as a contribution to Government's process of assessing vulnerability and adaptation options by: (i) assessing possible impacts on the water balance and on agriculture and rural livelihoods; and (ii) reviewing adaptation options and the priorities for government policies, strategies and investments.CC BY 3.0 IGOACTUAL EVAPOTRANSPIRATIONAGRICULTURAL PRODUCTIONAIRALTITUDEAMOUNT OF RAINFALLANNUAL PRECIPITATIONAQUIFERAQUIFERSARID AREASATMOSPHEREATMOSPHERIC HUMIDITYAVAILABILITY OF WATERAVERAGE ANNUAL RAINFALLAVERAGE RAINFALLBASIN MANAGEMENTBASINSBENEFICIAL USECALCULATIONCALIBRATIONCATCHMENTCATCHMENTSCIVIL SOCIETYCLIMATECLIMATE CHANGE ADAPTATIONCLIMATE CHANGE ADAPTATION MEASURESCLIMATE CHANGE ASSESSMENTCLIMATE CHANGE IMPACTCLIMATE CHANGE IMPACT ASSESSMENTCLIMATE CHANGE IMPACTSCLIMATE CHANGE ISSUECLIMATE CHANGE MODELSCLIMATE CHANGE PROJECTIONSCLIMATE CHANGE RISKSCLIMATE CHANGE SCENARIOSCLIMATE DATACLIMATE INDICESCLIMATE MODELLINGCLIMATE MODELSCLIMATE RESILIENCECLIMATE SCENARIOSCLIMATE SCIENTISTSCLIMATE TRENDSCLIMATE VARIABILITYCLIMATIC RESEARCHCLIMATIC ZONESCLIMATOLOGYCOASTAL AREASCOASTAL ZONESCOASTSCOMMUNITY WATERCONVERGENCECRUDECISION MAKERSDECISION MAKINGDESERTIFICATIONDESERTSDIESELDISTRIBUTION OF RAINFALLDIVERGENCEDROUGHTDRY CLIMATEECOLOGICAL ZONESEMISSIONSEMISSIONS SCENARIOEMISSIONS SCENARIOSENVIRONMENTAL PROTECTIONEROSIONEVAPOTRANSPIRATIONEXTREME EVENTSEXTREME RAINFALLEXTREME RAINFALL EVENTSEXTREME WEATHEREXTREME WEATHER EVENTSFARMERSFARMINGFLOOD RISKFLOODINGFLOODSFOGFUTURE CLIMATE VARIABILITYGCMGLOBAL CLIMATEGLOBAL CLIMATE CHANGEGLOBAL CLIMATE MODELGLOBAL EMISSIONSGROUNDWATERGROUNDWATER IRRIGATIONGROUNDWATER MININGGROUNDWATER RECHARGEGROUNDWATER RESERVESHIGH TEMPERATURESHIGH WATERHUMIDITYHYDROLOGICAL DATAHYDROLOGICAL MODELHYDROLOGICAL SYSTEMHYDROLOGICAL UNITHYDROLOGYICZMIMPACT OF CLIMATEIMPACT OF CLIMATE CHANGEIMPACTS OF CLIMATE CHANGEIMPORTSINCREASE IN TEMPERATUREINDICATOR OF CLIMATE CHANGEINDUSTRIAL USERSINTENSE RAINFALLINTERGOVERNMENTAL PANEL ON CLIMATE CHANGEINTERNATIONAL PANEL ON CLIMATE CHANGEIPCCIRRIGATION MANAGEMENTIRRIGATION SYSTEMSITCZLAND DEGRADATIONLOW RAINFALLMANAGEMENT OF WATERMANGROVESMAXIMUM TEMPERATUREMEAN TEMPERATUREMEASUREMENTSMETEOROLOGICAL AUTHORITYMETEOROLOGICAL DATAMETEOROLOGICAL ORGANIZATIONMONITORING STATIONSNATIONAL WATER RESOURCESNATURAL RESOURCESNEGATIVE IMPACTSPERMAFROSTPERMEABILITYPOTENTIAL EVAPORATIONPRECIPITATIONPRESSUREPROGRAMSRAINRAIN DAYSRAINFALLRAINFALL DISTRIBUTIONRAINFALL EVENTSRAINFALL INCREASESRAINFALL INTENSITYRAINFALL PATTERNSRAINFALL REDUCTIONSRAINFALL VARIABILITYRAINWATERRAINWATER HARVESTINGRAINY SEASONSREEFSREMOTE SENSINGRESPONSE TO CLIMATE CHANGERIVER BASINRIVERSSALINITYSEASEA LEVEL RISESEASONSEASONAL RAINFALLSERVICE PROVISIONSNOWSOIL CONSERVATIONSOIL MOISTURESOILSSPRINGSPRINGSSTAKEHOLDER INVOLVEMENTSTORM TRACKSSTORMSSURFACE RUNOFFSURFACE WATERTEMPERATE CLIMATETEMPERATURETEMPERATURE CHANGETEMPERATURE DATATEMPERATURE INCREASETEMPERATURE RECORDSTEMPERATURE REQUIREMENTSTEMPERATURE RISETEMPERATURESTEMPORAL RESOLUTIONSTEMPORAL VARIABILITYTROPICSUNEPUSE OF WATERVARIABILITY IN RAINFALLVARIABILITY OF CLIMATEVARIABILITY OF RAINFALLVULNERABILITY TO CLIMATE CHANGEWARMER CLIMATEWARMER TEMPERATURESWASTEWATERWASTEWATER REUSEWATER ABSTRACTIONWATER APPLICATIONWATER AVAILABILITYWATER CONSERVATIONWATER CYCLEWATER DEVELOPMENTWATER HARVESTING TECHNIQUESWATER MANAGEMENTWATER RESOURCEWATER RESOURCE MANAGEMENTWATER RESOURCES MANAGEMENTWATER SCARCITYWATER SECTORWATER SHORTAGESWATER USEWATER USESWATERCOURSESWATERSHEDWATERSHED MANAGEMENTWEATHER PATTERNSWELLSWINDWIND PATTERNSWINDOW OF OPPORTUNITYWINDSWMOWorld Bank10.1596/2943
