What is Environmental Data? • Environment == “catch-all” word • “Enviromental Data” Earth Sciences data • Athmosphere, oceans, biosphere • General feature • Collected on a geographical location • Either “in situ” or by remote sensing • In many cases, in “someone else’s backyard”

Challenges of Sustainable Development Unlike other factors of production (such as capital and labor), natural resources are inflexible in their location. The Amazonian Forest is where it is; the water resources for our cities cannot be very far away from them. The challenge posed by sustainable development is that we can no longer consider natural resources as indefinitely replaceable, and move people and capital to new areas when existing resources become scarce or exhausted: there are no new frontiers in a globalized world. (Daniel Hogan)
Sustainability Science Core Questions • How can the dynamic interactions between nature and society be better incorporated in emerging models and conceptualizations that integrate the earth system, human development and sustainability? • How are long-term trends in environment and development, including consumption and population, reshaping nature-society interactions in ways relevant to sustainability? • What determines vulnerability/resilience of nature-society interactions for particular places and for particular types of ecosystems and human livelihoods? Source: Sustainability Science Workshop, Friibergh, SE, 2000
Sustainability Science Core Questions • Can scientifically meaningful ‘limits’ or ‘boundaries’ be defined that would provide effective warning of conditions beyond which the nature-society systems incur a significantly increased risk of serious degradation? • How can today’s relatively independent activities of research planning, monitoring, assessment and decision support be better integrated into systems for adaptative management and societal learning?” Source: Sustainability Science Workshop, Friibergh, SE, 2000
Public Policy Issues • What are the acceptable limits to land cover change activities in the tropical regions in the Americas? • What are the future scenarios of land use? • How can food production be made more efficient and productive? • How can our biodiversity be known and the benefits arising from its use be shared fairly? • How can we manage our water resources to sustain our expected growth in urban population?
The Importance of Environmental Data • Our knowledge of earth system science is very incomplete • Support for earth science modelling • Understanding of processes • Supporting “conjectures and refutations” • Helps address sustainability science questions • From scientific questions to public policy issues • Data collection brings new questions and helps formulate new ones • Breaking the five orders of ignorance
The Five Orders of Ignorance • 0th Order Ignorance (0OI): Lack of Ignorance • I (provably) know something • 1st Order Ignorance (1OI): Lack of Knowledge • I do not know something • 2nd Order Ignorance (2OI): Lack of Awareness • I do not know that I do not know something • 3rd Order Ignorance (3OI): Lack of Process • I do not know a suitably effective way to find out that I don’t know that I don’t know something • 4th Order Ignorance (4OI): Meta-Ignorance • I do not know about the Five Orders of Ignorance The five orders of ignorance, Phillip G. Armour, CACM,43(10), Oct 2000
Why is Environmental Data Different? • Cannot be re-created or synthesized in a laboratory • Unlike data in Physical, Chemical and Biological Sciences • Requirement of access to a data collection size • Granted by mutual consent • Implicitly conceded by international conventions • Remote Sensing is ruled by COPUOS • Biodiversity collection is guided by Biodiversity convention • Extremely sensitive topic • Many governments and politicians think of data collection as “stealing our valuable resources”
Amazonia (LBA - GEOMA): Scientific Questions that need Good Data • What is the age of the trees in Amazonia? • What is the extension of the Amazonian wetlands? • What is the environmental impact of the forest fires? • What is the CO2 balance of the rain forest? • What are the driving factors of deforestation? • What are the true extent of biodiversity in Amazonia?
The Challenges • Data Collection over large regions is tough work... • Consequences • Sparse data • In many cases, limited by reachability of field campaigns • Fast degradation of infra-structure • Can indirect data help? • How can improvements in Remote Sensing help us? • There is a need for much more in situ data collection • What do you do with bad or incomplete data?
LBA Sites Operational site Planned site Up to 5 years of data Up to 3 years of data 1 to 2 years of data
Dados com boa taxonomia e bons dados de distribuição......... Flora Neotropica etc: Mimosoideae: Inga; Lauraceae: Nectandra;Sapotaceae, Chrysobalanaceae, algumas Annonaceae, Marantaceae: Montagma, etc, 1425 spp geo-referenciadas até grau de longitude/latitude e mapeadas em Arcview.
Data from Floras.................. Reserva Ducke: “Best kinown area in Amazonia” in 1993 (ca. 1100 spp.) By 1999, it had 2175 species, including between 50 – 100 undescribed ones........ Também: Saül (Guiana Francesa – Mori et al.) – 1997 & 2002. Iquitos (Vásquez et al.) - 1997 Flora of Ecuador (Renner et al.) – em progresso
Sapotaceae “densidade das espécies” Alto Rio Negro Saül Belém Santarém Tabatinga Rio de Janeiro
“1425 espécies” Isso é realmente a distribuição da diversidade de espécies neotropicais??? De jeito nenhum!!!!!

Modelling Deforestation in Amazonia • High coefficients of multiple determination were obtained on all models built (R2 from 0.80 to 0.86). • The main factors identified were: • Population density; • Connection to national markets; • Climatic conditions; • Indicators related to land distribution between large and small farmers. • The main current agricultural frontier areas, in Pará and Amazonas States, where intense deforestation processes are taking place now were correctly identified as hot-spots of change.
