Land Use and Cover Change

LBA questions by 1996:

  • Rates and mechanisms of forest conversion to agricultural use

  • Relative importance of different land uses

  • Dynamics and patterns of land conversion and abandonment

  • Area of forest affected by selective logging

  • Plausible scenarios of future land cover change

    Research strategy:

  • Basin-wide studies of rates and spatial patterns of deforestation

  • Case studies of patterns of deforestation and abandonment

  • Integration of socioeconomic factors and conditions

    Methods:

  • Satellite remote sensing, government statistics, survey data


Remote sensing in lucc research

Remote Sensing in LUCC Research

  • Satellite data provide temporal and spatial dimensions to study the dynamics of vegetation and its disturbances over a wide range of scales

  • Frequency of occurrence and extent of fires and distribution of atmospheric aerosols

  • Areas of expected new developments:

    • Radiative transfer modelling, forest regrowth stages, processing of active and passive microwave sensor images, atmospheric profiles of temperature and water vapour, cloud properties and precipitation

Land Use / Cover ChangeMajor developments

  • Rates and mechanisms of forest conversion to agricultural land uses

    • Total deforestation and average rates - 1-3x106 ha yr-1

    • Progress on case studies/few basin-wide analyses

    • Modest site representativeness (†); many critical areas ignored (†)

    • Mechanisms of forest conversion poorly understood(†)

  • Relative importance of different land uses

    • Census data still major source; other sources not representative (†)

  • Dynamics and patterns of land conversion and abandonment

    • Case studies helped to understand local dynamics (†)

    • Basin wide patterns and dynamics poorly understood (†)

  • Area of forest affected by selective logging each year

    • New developments from remote sensing and field surveys

    • Fate of the areas affected by selective logging to be better understood

  • Plausible scenarios of future land cover change - not much significant progress particularly due to items marked (†)

Land Use / Cover ChangeDataset development

  • Pathfinder and INPE datasets

    Land cover, deforestation and secondary vegetation

    Land use restricted to simplified forest/no for/defor/secondary vegetation

  • JERS-1 dataset

  • Flood plain mosaic

  • Airborne campaigns land cover: AVIRIS, LVIS

    How are these data to be treated in LBA DIS

Alves in press

Major effect of

concentration of forest clearings:

the development of a

spatial continuum where

pastures (and occasionally, grains)

dominate the landscape

Land Use and Cover ChangeEffects of concentration of forest clearing


Land use and cover change progress report 11 lba ssc meeting cena piracicaba 24 may 2002

Abstract submitted

Land use intensification - cattle increses faster than pastures. Family agriculture crops decline. Pastures increase their importance

Questions to be answered

From 1996 LBA objectives:

  • What are and where are the prevailing patterns ?

  • How does LUCC function for each of them ?

    Some “new” ones:

  • How they affect the carrying capacities ?

  • What are their characteristics related to land productivity and degradation ?

  • What are their characteristics related to urbanization, rural out migration and tenure structure (dynamics), rural conflicts, urbanization ... ?

    Remote sensing oportunities:

  • Patterns of landscape transfomation and deforestation

  • Patterns of landscape transfomation and land abandonment

  • Land degradation and productivity

Production systems

More questions to be answered (close work with MCT needed here):

  • What are the missing gaps/questions that MCT would see as relevant to LBA to focus on ? Will MCT direct any additional efforts into improving this component ?

  • How does MCT see the role of its Institutes within this component?

  • Will future MCT research programmes encompass this component ?

  • How does MCT see this component in comparison with other well organized Federal programmes like PPG7, Avança Brasil, and, particularly, agricultural research ?
