The main aim of the SSWM Toolbox is to be a reference tool to provide ideas for improving the local water and sanitation situation in a sustainable manner. Results depend largely on the respective situation and the implementation and combination of the measures described. An in-depth analysis of respective advantages and disadvantages and the suitability of the measure is necessary in every single case. We do not assume any responsibility for and make no warranty with respect to the results that may be obtained from the use of the information provided.

4 What are Ecosystems? (1/2) 1. IntroductionWhat are Ecosystems? (1/2)Ecosystem:Dynamic complex and interaction of living organisms (humans, animals, plants, microorganisms, ..) and the non-living environment (air, water, mineral soil, ...)Interaction of living organisms and the non-living environment through water cycle, nutrient cycle and energy flowsExample: interaction between water and plant through water cycle.Source: [Accessed: ]
5 What are Ecosystems? (2/2) 1. IntroductionWhat are Ecosystems? (2/2)Example: The Marine EcosystemSource: [Accessed: ]
6 Humans within the Ecosystems (1/2) 1. IntroductionHumans within the Ecosystems (1/2)Depend entirely on a functioning ecosysteme.g. quantity and quality of waterHave a major impact on the health of an ecosysteme.g. exploitation of groundwater through excessive irrigatione.g. pollution through inadequate sanitationHumans and the water cycle.Source: [Accessed: ]
7 Humans within the Ecosystems (2/2) 1. IntroductionHumans within the Ecosystems (2/2)Therefore:Sustainable sanitation and water managementare crucial for a more sustainableecosystem management.
8 Types of Ecosystem Services (1/2) Ecosystem Services = benefits people obtain from ecosystemsProvisioning servicesProducts from ecosystems: e.g. Food, timber, waterRegulating servicesBenefits from regulation of ecosystem processes: e.g. Water purification, control of climate, diseases, floodsCultural servicesSpiritual and recreational benefitsSupporting servicesMaintain the three other services: e.g. Water and nutrient cycles, photosynthesis, crop pollination
9 Types of Ecosystem Services (2/2) Demand for these services have been growing over the last decades.Enhancement of production of crops, livestock, aquacultureNegative impact on other services like water regulationUnsustainable water withdrawals for irrigation of agricultural land % of global irrigation withdrawals are estimated to be unsustainable.

10 Components of Human Well-Being 3. Changes in Ecosystems and Human Well-BeingComponents of Human Well-BeingGeneral components are:SecurityBasic material for a good lifeHealthGood social relationsFreedom in choice and action, which is enhanced by the previous components
11 Shortages of Ecosystem Services Affect Human Well-Being 3. Changes in Ecosystems and Human Well-BeingShortages of Ecosystem Services Affect Human Well-BeingLinkages between ecosystem services and human well-being. Source: MA (2005).
12 Only Partial Substitutability! 4. Substitutability and Human Well-BeingOnly Partial Substitutability!e.g. Substitutability of natural water purification:Limited amount of clean water from water filtersBUTdependence on economic status!
13 5. Drivers of Ecosystem Change Indirect drivers (1/2)Demography: global population doubled in the past 40 yearsEconomy:increase of global economic activity sevenfold between 1950 and 2000Taxes and subsidies increase resource consumption (e.g. Increase food production increase water consumption)Socio-Politics: a.o. Public participation increase in multilateral environmental agreements
14 5. Drivers of Ecosystem Change Indirect drivers (2/2)Culture and Religion: influence on consumption behaviour and environmental stewardshipScience and Technology: e.g. Advances in fishing industry depletion of marine fish stock
15 5. Drivers of Ecosystem Change Direct driversHabitat changeIn terrestrial ecosystems especially land-cover change to croplandOverexploitationOverfishing in marine ecosystemsInvasive speciesPollutionEsp. Freshwater ecosystemsClimate change
16 Human Reliance on Wetland Services 6. Wetland Services Under StressHuman Reliance on Wetland ServicesPopulation growth more people rely on wetland servicesFreshwater supplyNatural water purificationAquifer recharge
17 Agriculture and Wetland Services 6. Wetland Services Under StressAgriculture and Wetland ServicesPopulation growth more people rely on wetland servicesThis can result in:Regional water scarcity due to irrigationEutrophication of water bodies through excessive fertilizationSource: [Accessed: ]Source: [Accessed: ]
