Migration and Diversity
Introduction
Humans have endeavored to comprehend the relationship between geography and population dynamics since long ago. Research has established that population numbers does grow in an exponential manner while the production of food grows in a linear way as it does not keep pace with growth in population and hence leading to natural checks such as famine or drought (Sherbinin et al, 2009).
Research conducted in the Mwanza region of Tanzania which is located in the western part of Tanzania shows that accessible runoff is different in a significant way across some small region and also that population density nears the water that is available in a region (Marta, 2016). Migrants to urban centers are less likely to access water from standpipes and they are more likely to rely on wells that have not been improved.
Rural-urban migration does not correlate with relative water scarcity in places that people have come from but it correlates to how near people are to roads and to towns (Marta, 2016). There is a general conclusion that high fertility which was traditionally adapted to peak labor demands when there was short cropping season is likely to increase problems to do with access to water and the maintenance of its supply in areas known for agriculture and domestic spheres (Sherbinin et al, 2009). However, future shortages in water will fail to acknowledge the great portions of developing country populations do not have the access to water or the levels of consumption being witnessed by international bodies (Marta, 2016). This same trend is similar in the Pangani Basin of northern Tanzania. There are myriad factors that bring about the conflicts to water resources and hence displacement in population in those regions.
