Technical Report: Lagos floods

Abstract: Lagos faces increasingly severe annual flooding, exacerbated by sea level rise and subsidence. In 2021, floods again submerged vehicles and houses, displacing thousands from their homes. The demand for sand in construction materials drives illegal sand mining and erosion on the coast of Nigeria, degrading ecosystems and increasing flood risk. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions … Show more

Subject. The article considers methodological approaches to the definition of the concept and assessment of indirect economic damage from changes in the level of Lake Baikal. Objectives. The aim is to analyze the adequacy and practical suitability of methodology for assessing the probabilistic damage from harmful effects of water and the effectiveness of preventive water management measures, developed by the All-Russian Research Institute of Economy and Exploration of Mineral Resources (VIEMS). Methods. On the basis of comparative analysis of results obtained under the direct counting method and those under the VIEMS methodology, we underpinned the adequacy of the latter. Results. We used the case of Nizhneangarsk settlement to make estimates of indirect economic damage under the method of direct counting and the VIEMS methodology. The results are comparable, and this enables to speak about the adequacy of the VIEMS methodology . Conclusions. The comparative analysis demonstrates the reliability of results of assessing the indirect economic damage, obtained using the VIEMS methodology. Significant labour intensity, complexity, and often impossibility of estimation by the direct counting method make it possible to substantiate the feasibility of practical application of the VIEMS methodology for assessing indirect economic damage from the negative impact of waters.

Tulisan ini akan mengkaji tentang politik pengelolaan air bersih sebuah tinjauan atas langkanya kualitas air bersih di Kampung Kedungringin Kecamatan Sukawangi Kabupaten Bekasi. Alasan penelitian ini dilakukan adalah karena terjadi persoalan di Kampung Kedungringin yakni tidak adanya akses terhadap air bersih baik secara kualitas maupun kuantitas. Berbagai upaya telah dilakukan oleh masyarakat Kampung Kedungringin seperti membangun sumur bor dengan bantuan dari para dermawan. Namun hal ini belum cukup untuk memenuhi kebutuhan air bersih bagi seluruh warga. Peran PDAM Tirta Bhasasi pun dalam hal ini belum mampu menjangkau wilayah Kampung Kedungringin karena Saluran Pipa Air Bersih jauh dari lokasi Kampung Kedungringin. Dengan permasalahan tersebut, maka penelitian ini akan mengkaji terkait bagaimana upaya yang dilakukan PDAM Tirta Bhagasasi dan Pemerintah Desa Sukaringin dalam memenuhi akses kebutuhan air bersih di Kampung kedungringin. Metode Penelitian yang digunakan dalam penelitian ini adalah metode penelitian kualitatif deskriptif dengan pendekatan studi kasus. Hasil penelitian ini menunjukkan bahwa upaya yang dilakukan PDAM Tirta Bhagasasi dalam memenuhi kebutuhan air bersih bagi masyarakat Kampung Kedungringin belum terealisasi. Hal ini dikarenakan PDAM Tirta Bhagasasi dalam pembangunan saluran pipa air bersih baru sampai ke wilayah perumahan/cluster di Desa Sukaringin. Air bersih belum bisa mengalir ke Kampung Kedungringin karena PDAM Tirta Bhagasasi lebih memprioritaskan Kawasan perumahan cluster bekerjasama dengan pengembang. Itu artinya kelompok masyarakat yang mempunyai uang akan lebih diprioritaskan daripada kelompok masyarakat yang tidak mempunyai uang.

Lagos has been identified as one of the 50 cities most vulnerable to extreme sea levels. The state also ranked 30th among 136 port cities in terms of population exposure to flooding under a past climate scenario (2005) and 15th under a future climate scenario (2070s). The state faces significant environmental strains as a result of its geo-economic status. Some of the problems are wetland loss, pollution, population pressure, restricted access to drinkable water, and flooding. All these factors have contributed to the instability of Lagos ecosystems, but the impact of flooding is particularly significant because Lagos is surrounded by aquatic ecosystems and its low elevation and topography increase its susceptibility to flooding. The method adopted in this review involved the use of PICO (Population, Intervention, Control, and Outcomes) criteria to synthesize the research questions and objectives. Thereafter, PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines was employed for the study selection criteria, search strategies and data extraction methods. A broad search strategy involving databases (Google scholar, Science Direct), pertinent keywords and search filters was used to identify relevant articles and minimize selection bias. After the search, PICO criteria was again used to select the studies to be considered in the review. The selected text were downloaded and the essential scientific information were extracted and analyzed in the study. The impacts of flooding are numerous. Flooding is a key factors that has prevented Africa’s growing urban population from escaping poverty, and it also impedes the achievement of some SDGs. This is because many African cities lack the resources and infrastructures needed to withstand extreme weather conditions. Surviving in flood-prone cities like Lagos is a daunting task because flood affects livelihood, human health, and can even cause death. Specifically, the 2020 flood incidence in Nigeria affected about 40% of the local government areas, and 97% of the states, displacing over 120,000 persons and killing 68 persons aside from properties and farmlands destroyed. Women and children are the most vulnerable. The adoption of advanced flood risk management strategies could help in flood containment and management in the state.
