Abstract

Hwange National Park, the largest national park in Zimbabwe, has been recorded as experiencing elephant migrations to neighbouring Botswana for several years due to drought-related dryness of water bodies. The adverse impacts of climate change have led to a rise in Zimbabwe's annual mean surface temperature, rendering the country more susceptible to drought conditions and decreased rainfall. To investigate the directional trend of elephant migration patterns from Hwange National Park to neighbouring Botswana, spatiotemporal analysis was conducted from 2009 to 2017 using ArcGIS Pro software. Secondary data was utilized for analysis, with elephant migration data abstracted from Movebank, an open-source data portal for large collections of animal tracking data. These migration patterns were remotely tracked through GPS sensors. Additionally, annual mean surface temperature data, sourced from the International Monetary Fund's climate data, was considered an allied factor with the fundamental objective of the research. A bar chart was created to represent the temperature data statistically. The results emphasized that annual mean surface temperature fluctuations in Zimbabwe have influenced elephant migration, with high surface temperatures recorded in 2010, 2015, and 2016 accompanied by increased migrations. Consequently, the elephants' tendency to migrate towards Botswana has gradually risen throughout the period, underscoring the adverse impacts of climate change.

Abstract

Over the past decade, the Southwest coast of Sri Lanka has experienced recurrent coastal floods, particularly in the stretch from Akurala to Godagama. This study, spanning from 2010 to 2020, seeks to unravel the factors influencing these floods, filling a void in existing research on the subject. Employing topographic maps, field observations, and bathymetric data from the Lanka Hydraulic Institute and Coastal Conservation Department, the research delves into geomorphological features and elevation variations in the study area. Findings indicate that high elevation in the Ambalangoda to Akurala and Godagama to Hikkaduwa regions contributes to coastal flooding, as these areas are elevated above the mean sea level. The bathymetric analysis exposes closely spaced contours and steep slopes, exacerbating flooding when waves collide with the coastline. The absence of mangroves amplifies the impact, distinguishing the study area from its neighbouring regions. Socioeconomic consequences include road closures, accidents on the Galle-Colombo main road in 2020, and adverse effects on fisheries and tourism. Environmental impacts encompass coastal erosion, degraded water quality, coral bleaching, and saltwater intrusion. While artificial structures like rock barriers mitigate flooding, the study underscores the interplay of land morphology, bathymetry, land use, and climate influencing coastal flooding along the Akurala to Godagama coast.
