23 - Slide 23 DAAD Workshop New Delhi "INDIEN", 27. April 2007 Monsoon as a "resource" Blessing & benediction versus malediction & curse Basic rule: Monsoon precitipitation represents a limited, even insufficient resource for prosperous agricultural landuse. Hence, supplementary irrigation is required for flourishing landuse.

24 - Slide 24 DAAD Workshop New Delhi "INDIEN", 27. April 2007 Bottle-necks of monsoon precipitation: late onset - early withdrawal as a result, length of rainy season shortened below the minimum length of the growth period for rainfed crops (> need of supplementary irrigation) "failure" of the monsoon (= seriously below-normal monsoon precipitation) leading to drought(s) and famine(s) if no compensation by irrigation deficient monsoon precipitation minimizes supply of irrigation water through surface-runoff and underground water aquifer (hence shrinking double-, or even triple-cropping system that is needfully necessary for self-sufficiency in food production, particularly in view of the heavy population load) heavy precipitation also negatively affects landuse and crop production (rainstorms > floods, soil erosion and loss of fertile surface soil)

25 - Slide 25 DAAD Workshop New Delhi "INDIEN", 27. April 2007 As a consequence: Monsoon precipitation must be well-balanced (= "normal" distribution over time and space) for optimum crop production in order to satisfy the demand for quality and quantity productivity

30 - Slide 30 DAAD Workshop New Delhi "INDIEN", 27. April 2007 Outlook Impact of warming on human environment & societies The most widely discussed topics and scientific concern are on: - sea level rise and vulnerability of human settlements in coastal/riverine locations, by innundation, coast erosion, groundwater salinization; increasing tidal flats and height/severity of tides - increasing extreme weather events, such as rainstorms, windstorms, floods and droughts, tornados and tropical cyclones, and hail - greater health risk by floods, water contamination and altered patterns of vector- bourne infectious deseases - great and costly extent of climate warming on urban settlement, for example, from overwhelmed urban storm drains and sewers during extreme rainfall events, particularly in low-lying urban areas and affecting most seriously marginal populations - negative climate change impact on urban construction and infrastructure/ transportation by higher costs for disaster rehabilitation

31 - Slide 31 DAAD Workshop New Delhi "INDIEN", 27. April 2007 Outlook Ultimate question: Adaptation of human environment and societies by sustainable development?!
