“…Defined as "an overflow of water beyond the normal limits of a watercourse" [1], flood events have the potential to be highly destructive to communities, both socioeconomically and environmentally [2]. Floods impact the largest number of people across all natural hazards globally, accounting for one-third of all natural disaster casualties and damages [3,4]. The annual expected costs of global floods have been estimated at just over $160 billion (2022 AUD inflation adjusted) [5].…”

Floods are among the costliest natural hazards, in Australia and globally. In this study, we used an indicator-based method to assess flood hazard risk in Australia’s Hawkesbury-Nepean catchment (HNC). Australian flood risk assessments are typically spatially constrained through the common use of resource-intensive flood modelling. The large spatial scale of this study area is the primary element of novelty in this research. The indicators of maximum 3-day precipitation (M3DP), distance to river—elevation weighted (DREW), and soil moisture (SM) were used to create the final Flood Hazard Index (FHI). The 17–26 March 2021 flood event in the HNC was used as a case study. It was found that almost 85% of the HNC was classified by the FHI at ‘severe’ or ‘extreme’ level, illustrating the extremity of the studied event. The urbanised floodplain area in the central-east of the HNC had the highest FHI values. Conversely, regions along the western border of the catchment had the lowest flood hazard risk. The DREW indicator strongly correlated with the FHI. The M3DP indicator displayed strong trends of extreme rainfall totals increasing towards the eastern catchment border. The SM indicator was highly variable, but featured extreme values in conservation areas of the HNC. This study introduces a method of large-scale proxy flood hazard assessment that is novel in an Australian context. A proof-of-concept methodology of flood hazard assessment developed for the HNC is replicable and could be applied to other flood-prone areas elsewhere.

“…Previous studies have established a relationship between the annual floods and Port Harcourt's poor urban planning (Chukwuma & Uchenna, 2018;Dan-Jumbo et al, 2018). Other studies found that poor construction and coordination of drainage systems are root causes of the flooding problem in urban areas (Ogundele & Jegede, 2011).…”

‘Not Going to Plan’: Urban Planning, Flooding, and Sustainability in Port Harcourt City, Nigeria

Flooding is the most widespread environmental disaster in Nigeria and flooding impacts are exacerbated by poor urban planning. Flooding is a direct impediment to Nigeria achieving its sustainable development goals (SDGs). While urban planners are responsible for implementing policy changes to address the issue of flooding, there is very little research that explores their views on the linkages between urban planning, flooding, and public policy. Using the city of Port Harcourt, Nigeria, as a case study, this paper presents data from interviews with practicing urban planning professionals. It argues that Port Harcourt's urban planners have a sound understanding of principles of sustainability and are fully aware of the connections between poor urban planning and flooding. They do however see widespread public non-compliance with planning laws and improper building approvals, rather than systemic failures of governance, as the main issues that undermine the city's legal and planning architecture put in place to control floods.

“…The contribution of mining to the GDP in Nigeria is 0.15 per cent. During the colonial period, coal and tin occupied high positions as sources of Nigeria's foreign exchange earnings, and after the country gained independence in 1960, other minerals such as limestone, gold, marble, clay, etc., were mined to a lesser extent, mainly for local consumption [136]. This country is an important case from the perspective of our country, as Poland is considering the possibility of importing raw coal from this country.…”

Energy transition is one of the main objectives of the European Union. Significant changes will mainly affect countries in which significant modifications will have to be made to their energy sources. The process will involve high investment in infrastructure and additional costs of the transformation, such as reduced production (which may affect the GDP value) in the economic sectors involved in the process. The aim of this article is to provide the energy transition community, namely the national economy in general and those involved in planning for structural change in particular, with the key lessons and challenges in researching the impact of production changes in the mining sector. This article also shows the relevance of the mining sector in the economy. Within this area, particular attention is given to the following issues: the impact of economic sectors on the country’s GDP (gross domestic product); the identification of key sectors of the economy using the input–output method; the contribution of coal mining and the mining industry to Poland’s GDP; an analysis of changes in the structure of Poland’s economy using the input–output method; and the use of the input–output method in the context of changing/reducing the supply of economic sectors.
