The analysis of COVID-19 pandemic precarity in Africa should focus on the ways in which pre-pandemic migrant vulnerabilities were reconfigured in ways that weakened economic resiliency and reinforced disadvantage. This is the first paper to apply the concept of pandemic precarity to the impact of COVID-19 on migrants working in the informal food sector of African cities. The paper develops a new method for measuring pandemic precarity and applies this to data from a 2021 survey of migrant-owned informal food enterprises in the city of Cape Town. The Informal Pandemic Precarity Index (IPPI) and Informal Pandemic Precarity Scale (IPPS) are …

No. 14: Food Insecurity And Irregular Labour Migration From Northern Malawi To South Africa, Anil Dhakal
Migration and Food Security (MiFOOD) Network
The factors influencing migration decisions from Malawi to South Africa have changed with the end of contract migration to the mines and the new normal of irregular migration of both men and women to work in other sectors of the South African economy. Food insecurity is now one of the main drivers of migration as migrants seek to earn income to remit to family in Malawi to purchase food and to invest in agriculture. Food insecurity is normally associated with rural households, but this paper shows that it is also a driver of migration to South Africa from urban Malawi. …

Over the last 10,000 y, humans have manipulated fallow deer populations with varying outcomes. Persian fallow deer (Dama mesopotamica) are now endangered. European fallow deer (Dama dama) are globally widespread and are simultaneously considered wild, domestic, endangered, invasive and are even the national animal of Barbuda and Antigua. Despite their close association with people, there is no consensus regarding their natural ranges or the timing and circumstances of their human-mediated translocations and extirpations. Our mitochondrial analyses of modern and archaeological specimens revealed two distinct clades of European fallow deer present in Anatolia and the Balkans. Zooarchaeological evidence …

Recovery Of Microtopography Following Prairie Restoration: Implications For Biodiversity Monitoring, Karli Cich, Scott Powell
The Geographical Bulletin
Tallgrass prairies are often restored from agricultural fields where the natural microtopography has long since been removed. Therefore, our study investigates the degree to which restored prairies recover microtopography. Differences in microtopography were measured using precise elevation data collected from LiDAR to compare differences in microtopography between crop fields, fallow fields, newer restored prairies, and older restored prairies. We also compared plant biodiversity indices between newer and older restored prairies using nested plot vegetation sampling. Our first research question is how microtopography differs between the sites. Our results show that older restored prairies had the most microtopographic variation, followed by …

Modeling The Impact Of Ocean Temperature Increases On The Distribution Of Seagrasses Around The Korean Peninsula Using A Machine Learning Technique, Jina Jang, Seohyeon Kim, Jeong Seong
The Geographical Bulletin
Seagrasses are important resources which form a vital part of the ocean ecosystem. They are also considered blue carbon because of their capability of sequestrating carbon. Seagrass distribution can be affected by many factors including ocean temperature. It is highly likely that recent climate change may increase ocean temperature significantly in East Asia and consequently alter seagrass distribution patterns. This study aims at predicting the impact of ocean temperature increases on seagrass habitats around the Korean Peninsula. Using the Maximum Entropy (MaxEnt) Model, seagrass habitat distributions were modeled when sea temperature rises by 1°C, 2°C, 3°C, and 4°C. Results show …
