Objective of the LAND Project:
To identify changes in the human-environment system and critical thresholds of vulnerability at local, regional and global scales of the system.
![Page 6: IGBP-II LAND Research Program](https://reader033.vdocument.in/reader033/viewer/2022061322/56814c56550346895db970e3/html5/thumbnails/6.jpg)
Fundamental Principles for LAND research
First, integrating for Transition to sustainability‘functionalities’ or characteristics of the Earth System
• feedbacks (processes which amplify or dampen aspects of the dynamics of the planetary life-support system),
• teleconnections (linkages between processes across space), • switch and choke points on the earth’s surface (control
points).
Second, Integrative with other sciences, as possibleThird, a fruitful platform of investigations - exploration of pathways (or trajectories) of land change
![Page 7: IGBP-II LAND Research Program](https://reader033.vdocument.in/reader033/viewer/2022061322/56814c56550346895db970e3/html5/thumbnails/7.jpg)
Major Concepts to consider
Ecosystems as life-support systems Pathways of change (trajectory analysis)People and ecosystems at risk (vulnerability )Methodological issues
Coupled (socio-economic and biophysical) models Linked, geo-referenced and long-term databases of socio-economic and biophysical variables Comparative regional assessments:

THE LAND ProjectLand-Centric integrative research programmeGuiding Questions of the Research Agenda are:
1. What are the dynamics and drivers of variability and change in human-environment systems?
2. How is the provision of environmental goods and services affected by changes in human-environment systems?
3. What are the characteristics and dynamics of vulnerability in human-environment systems?

Research Questions (1)How do economic growth, globalization, governance, and other socio-economic processes interact to drive changes in land use and the functioning of the land system? How does the changing spatial distribution of land use, urbanization, changing populations, and settlement patterns to drive changes in the land system, and in land-atmosphere, land-ocean exchanges?How do management of land systems and disturbances drive changes in the land system, and its interaction with the atmosphere and oceans?
![Page 11: IGBP-II LAND Research Program](https://reader033.vdocument.in/reader033/viewer/2022061322/56814c56550346895db970e3/html5/thumbnails/11.jpg)
Research Questions (2)How does the legacy of historical management and disturbance, drive changes in the land system, and its interactions with the atmosphere and oceans now and in the future?How do environmental changes and human activities drive changes in biodiversity and how do these effects feed forward to cause changes in ecosystem functioning and properties?How does the changing physical and chemical atmosphere interact with the land to drive changes in land systems, land-atmosphere and land ocean exchanges?
![Page 12: IGBP-II LAND Research Program](https://reader033.vdocument.in/reader033/viewer/2022061322/56814c56550346895db970e3/html5/thumbnails/12.jpg)
Focus on Integrated Research Activities:
Agriculture impacts and feedbacks• An integrative systems analysis• Land scarcity and degradation• Impacts of the inputs and flow
MEGA-BASINS: How do biophysical and human-decision interactions control vulnerability of mega-basins?
• Water Resources – Availability, Development and Management
• Water-Food-Economic Production System Interactions• Upstream-Downstream Links (Material Flows)

Monsoon Asia Integrated Regional Studies
1. Emissions/Energy/industrial transformations – 2. Climate-related Disasters and Hazards
– floods, droughts, storms, fires, GLOFs
3. Water (fresh and salt), catchments and coasts 4. Food, Fiber 5. Human health 6. Biodiversity and ecosystem change + Ecosystem services
Cross-Cutting Themes : Land Use; Monsoon climate system Resilience;
Adaptive capacity; Ecosystem services
![Page 37: IGBP-II LAND Research Program](https://reader033.vdocument.in/reader033/viewer/2022061322/56814c56550346895db970e3/html5/thumbnails/37.jpg)
Water-Food Theme
1. How will changes in land-use and cover, atmospheric emissions, and ocean productivity in the Asian Monsoon region interact with the global hydrological cycle?
2. What will be the consequences of changes in land-use, and modification of rivers for ground water, riverine, coastal and marine environments?
3. Will these changes amplify vulnerability to (the natural and man-made disasters like) floods and droughts
–Food Production Systems

Vulnerability Theme
How will changes in the AM, especially the frequency and intensity of extreme event challenges human responses?
How do rapid economic and social changes influence vulnerability to hazards?
How many changes in frequency/severity of biological invasions, pests, weeds and diseases affect human well-being?
How can human-decision making be improved to reduce disasters under both current and future environmental conditions?
