Population Growth

Population growth has been a significant factor shaping the dynamics of global development and resource utilization. For centuries, population size and growth rates have been a topic of concern, with the global population surpassing 7.8 billion by 2020. This exponential growth presents multifaceted challenges as well as opportunities. The United Nations, recognizing the intricate ties between population growth and global challenges, incorporated it indirectly into the Sustainable Development Goals (SDG) in 2015. The SDGs, consisting of 17 interconnected objectives, aim to eradicate poverty, safeguard our planet, and ensure prosperity for all by 2030. These goals, though not directly mentioning population growth, are profoundly influenced by it. Here's how:

Firstly, rapid population growth intensifies the strain on limited resources, especially in regions where these resources are already scarce. This is pertinent to SDG 2 (Zero Hunger) and SDG 6 (Clean Water and Sanitation). As the population burgeons, more food is required, leading to intensified agricultural practices, which may not always be sustainable. Similarly, the demand for freshwater rises, pressuring our freshwater reserves and causing potential conflicts over these vital resources.

Secondly, the influx of people in urban centers due to population increase is undeniable. By 2050, it's estimated that two-thirds of the global population will reside in cities. This massive urban migration and city population boom challenge SDG 11 (Sustainable Cities and Communities). Urban areas require sound infrastructures, sustainable transport, and adequate housing – all of which become even more pressing with rapid population growth.

Next, with more people, there's a higher demand for affordable and quality healthcare, relating directly to SDG 3 (Good Health and Well-being). Overpopulated regions often grapple with the spread of diseases, lack of medical facilities, and inadequate healthcare professionals, making the attainment of this goal more strenuous.

Additionally, the increasing global populace necessitates quality education for all, echoing the aims of SDG 4 (Quality Education). As populations grow, especially in developing nations, there is an urgent need to provide education to a larger number of children and young adults, requiring more schools, teachers, and educational resources.

Environmental concerns are also paramount. A greater number of people means more waste, more demand for energy, and more carbon emissions. This directly affects SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land). Higher populations can intensify deforestation, lead to increased greenhouse gas emissions, and expedite the degradation of marine and terrestrial ecosystems.

However, it's essential to note that population growth isn't just a challenge; it's also an opportunity. A growing population means a larger workforce, more innovative minds, and potentially a bigger market for goods and services. Countries can harness this 'demographic dividend' for economic growth if they can adequately invest in health, education, and employability of their people.

This book chapter addresses goals 11, 12, and 15 by showing that human population growth is not the only matter for consideration in ecological engineering. What matters for the future is not only how many people there will be, but what they will do in their everyday life; this will impact the life systems surrounding them and how equipped they will be to face emerging challenges. In coming decades, the survival and well-being of humans and the security of environmental resources will continue to be challenged by rapid population growth.

This chapter will attempt brief review on some of the known factors which define populations, particulary developing countries, at special risk for chemical toxicity from e-waste. The goal of SDG target 3.9 is to substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination

The sustainability of water resources depends on the dynamic interactions among the environmental, technological, and social characteristics of the water system and local population. These interactions can cause supply-demand imbalances at diverse temporal scales, and the response of consumers to water use regulations impacts future water availability. This research develops a dynamic modeling approach to simulate supply-demand dynamics using an agent-based modeling framework that couple models of consumers and utility managers with water system models.

Focuses on homelessness from a public health perspective – its prevalence, its relationship to specific health conditions, and various interventions intended to ameliorate homelessness and the health problems with which it is associated.
Rule of law course presenters
For the rule of law to be effective, there must be equality under the law, transparency of law, an independent judiciary and access to legal remedy. Yet about 57% of the world's population lives outside the shelter of the law. This presentation and training video demonstrates how advancement of the rule of law benefits economic prosperity and advancement of society and what role businesses and lawyers can play to advance SDG 16.3 to promote the rule of law at the national and international levels and ensure equal access to justice for all.

The economic crises seems blinding the governments and major economic actors toward environmental troubles. Nevertheless, the impacts of population growth and economic expansion have now the potential to disrupt important regulatory functions of global ecological systems. Green growth involves transforming the production and consumption processes in order to maintain or restore these regulatory functions of the planet's natural capital. It requires that environmental facto rs be treated as an essential factor of production and not merely an externality.
