Global Change A review of current issues Jean P. Malingreau Seminar on Global Change Universitas Gadjah Mada Pascasardjana Yogyakarta October 2019 We live strange times……. Affluence, mobility, material well being, health have signicantly improved since the 50ies . The earth’s resources and environment are submitted to strong pressures, to sometimes alarming levels. Some people are announcing that because of human occupation of the earth we are now getting closer to the end of the world….! We have 12 years to limit climate change catastrophe………. warns the UN. Teenage activist Greta Thunberg, “We are less than 12 years away from not being able to undo our mistakes.” Alexandria Ocasio-Cortez, in front of a crowd in New York City in January “The world is going to end in 12 years if we don’t address climate change.” Is this correct? Does it help? A new vocabulary has appeared: …….. Collapsing earth A global systemic catastrophy Extreme events Run away ecosystems 12 years to the end (?) Collapsology, collapsonauts, collapsosophy Disasters Climate justice ..…… Another End of the world Is possible (to live the collapse and not only survive it !) Is this the future…??? Apollo 8 Dec. 24.1968 This is our planet. Did you say « global »….? - A global phenomena - A local event with global incidences - A global attention - A global perspective Or…a continuum : individual, local, national, regional, continental, global - Global pressures - Global concern and responsability - Global management - Indonesia and global situation GLOBAL CHANGE DESCRIBES THE CHANGES THAT ARE TAKING PLACE IN THE ATMOSPHERE, HYDROSPHERE, BIOSPHERE AND LITHOSPHERE OF THE EARTH AT A PLANETARY SCALE AND IN THE SPAN OF HUMAN LIFE TIME RATIONALE- to be discussed during series of seminars A. WHY develop and maintain global understanding ? Why is it important for Indonesia? from size to power from national concerns to global responsabilities ………. B. WHY attempt to project in the future ? Foresight Man has become the major force in driving changes on the earth and some have argued that we have now entered the « Anthropocene » The Anthropocene defines Earth's most recent geologic time period as being human- influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric and other earth system processes are now altered by humans. Discussion Societal system has taken over natural systems What about in the long term ? sustainable development résilience of ecosystems, bounce-back effect …etc? ! One geophysical event (e.g. earthquake, volcanic eruption and ashes, tsunami) may have more far reaching effects than human impact. Is man too arrogant?

OR The Main Challenge for the 20-50 period SECURING THE TRANSITION : satisfying the needs of a growing and more demanding population while progressing from an unsustainable to a sustainable world Towards reaching full satisfaction of needs in 2050…? An global examination resources and environment questions is critical for several reasons: Scientific understanding of the earth system Addressing geopolitical issues related to the management and sharing of space and resources Economic development (markets are global) Individual concerns : solidarity, ethics, sharing, Professional The 2000 era: Addressing global issues (ecosystem services, resources, climate) Answering societal needs (food, energy, security) Supporting policies Focus is on detecting , measuring and understanding the « D » Searching for the « D » 12000 El Niño La La Niña El Niño La Niña El Niño A El Niño 10000 Pinatubo 8000 6000 4000 2000 0 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Year D = Xt2 – Xt1 Requires definition of : • Measured parameter (X) • Reference period (t2-t1) • Territory over which measurement applies (!

Yes, says the FAO…..but Will everyone have access to nutritious food Probably 1 billion experiencing food deficiency –(obesity!) Can we grow/raise/harvest food in a sustainable manner? Not there yet? THE NUMBER OF UNDERNOURISHED PEOPLE IN THE WORLD HAS BEEN ON THE RISE SINCE 2015, AND IS BACK TO LEVELS SEEN IN 2010–2011 MONITORING ? With global food production matching growth in the global population, significant pressure is now being placed on the functionality of the Supply Chains required to deliver this food to the customer.
