What is LPJmL MODEL.pptx

  1. 1. PRESENTATION ON LPJmL MODEL AND IT'S APPLICATION
  2. 2. PRESENTER INFORMATION Alex ujong Obeten 2022B8018137009 Msc Environmental Science Name Institute of urban Environment Chinese Academy of sciences. Degree University Nigeria Country
  3. 3. • WHAT IS "LPJmL MODEL" • BRIEF. HISTORY OF LPJmL MODEL • APPLICATIONS O LPJmL MODEL • CONCLUSION OUTLINE
  4. 4. WHAT IS LPJmL MODEL? • LPJmL stands for Lund Potsdam Jena Managed Land ( Bondeau et al 2007) • model has been developed from LPJ (Sitch et al 2003) a Dynamic Global Vegetation Model (DGVM) • provides a suitable modeling framework to assess grassland dynamics, grassland productivity, and the impact on the biogeochemical
  5. 5. LPJmL DEALS WITH ? • Process‐based dynamic vegetation model, originates from EPIC and BIOME models • Simulates plant responses to climate and climate change • High spatial and temporal resolution Photosynthesis Soil water Example DGVM output Source :wikipedia
  6. 6. BUSINESS BUSINESS BUSINESS BUSINESS BUSINESS HISTORY OF LPJmL MODEL
  7. 7. LPJmL MODEL INVOLVES? Inlight of the strengthening human interferences,DGVMs were further developed to integrate additional processes that are relevant to the original research quest of studying biogeography and biogeochemical cycles under climate change.
  8. 8. LPJmL MODEL INVOLVES? The incorporation of human land-use and the simulation of agricultural production systems,nutrient limitation,as well as hydrological modules and river routing schemes.
  9. 9. BUSINESS BUSINESS BUSINESS MAIN FEATURES OF LPJmL MODEL
  10. 10. FEATURES • Higher diversity can yield different results • Amount of variability may be positively correlated with resilience small changes result in big differences
  11. 11. APPLICATION OF LPJmL MODEL • Modelling Mediterranean agro-ecosystems by including agricultural trees in the LPJmL model • Modeling vegetation and carbon dynamics of managed grasslands at the global scale with LPJmL 3.6 • Evaluation of ecosystem dynamics, plant geography and terrestrial carbon cycling in the LPJ Dynamic Vegetation Model • Implementing the nitrogen cycle into the dynamic global vegetation, hydrology, and crop growth model LPJmL (version 5.0)
  12. 12. APPLICATIONS OF LPJmL MODEL
  13. 13. Part 02 FUTURE IMPROVEMENT OF LPJmL • Refine management modules (irrigation, rainwater harvesting and vapor shift techniques, multiple cropping) • Add more crops (potato, cotton, date palm, citrus, …) • Continue development of bioenergy plants • Understand uncertainty in CO2 fertilization effect (coupled effects from increased temperatures and CO2) • Improve grassland management and representation of livestock • Revise simulated impacts of extreme temperature and precipitation
