A fully mechanistic model based on diffusion equations for gas transport in a flooded rice system is presented. The model has transport descriptions for various compartments in the water-saturated soil and within the plant. Plant parameters were estimated from published data and experiments independent of the validation experiment. An independent experiment is described in which the diffusion c...

Extensive tropical floodplain wetlands, such as the Brazilian Pantanal, are complex ecosystems composed of mosaics permanently and seasonally flooded habitats increasingly threatened by land use climate change. Spatial interannual variability in seasonal flood pulse is a fundamental ecological driver these ecosystems. This study analyzes optical imagery from Sentinel-2 satellite to determine ex...

Abstract As a metal immobilizer, biochar can be used to remediate contaminated soil. Biochar’s effect on the phytoremediation process in flooded conditions under scenario of increasing flooding frequency as global climate change is not well understood. This study investigated bamboo (BBC) effects growth and accumulation Salix multi-metal soil non-flooded versus conditions. cuttings were cultiva...

This paper reviews the need for a new land administration vision that takes a more integrated approach rather than the historic fragmented approach and examines change management of land administration and cadastral systems in the context of global drivers of change. This results in the development of a framework for re-engineering land administration systems. After discussing a land administra...
