An investigation of coastal vulnerability and internal consistency of local perceptions under climate change risk in the southwest part of Bangladesh

Bangladesh is one of the most disaster-prone countries, while climate change and its associated hazards such as cyclonic storm surges, inundation, and salinity threats force disruption of coastal communities.

Perspectives on measures for adaptively managed erosive shorelines: A case study in Sri Lanka

The success of adaptive management depends on the interpretation of the archived data of each feedback loops. Archived data are limited or difficult to access in developing countries due to lack of budget, technical expertise, institutional coordination etc. Figure 1: Photos of shore next to a tourist hotel after beach nourishment in 2016 December (Photos were taken during my recent field visits) Historical changes in the shoreline and management of Marawila Beach, Sri Lanka, from 1980 to 2017 Coastal management in Sri Lanka is […]

Suppose that a main script of [cci]main.py[/cci] (or a corresponding [cci]Jupyter Notebook[/cci]) exists in the directory of [cci]myproject[/cci], and its subdirectory [cci]sub[/cci] contains modules of [cci]mod_a.py[/cci] (a function of [cci]func_a ()[/cci] included) and [cci]mod_b.py[/cci] (a function of [cci]func_b()[/cci] included) where [cci]main.py[/cci] imports the module [cci]mod_a[/cci] and the module [cci]mod_a[/cci] imports the module [cci]mod_b[/cci]. First, creating an empty file [cci]__init__.py[/cci] in the directory [cci]sub[/cci] so that [cci]sub[/cci] is recognized as a package as shown below: [cc] myproject/ main.py sub/ __init__.py mod_a.py (func_a()) mod_b.py (func_b()) [/cc] The sub-directory, [cci]sub[/cci], containing two modules, becomes a package when [cci]__init__.py[/cci] is included.
