Demographic Transition Model, Food Security, and Population Growth

This report delves into the demographic transition model, outlining its stages and the factors influencing population growth. It discusses the model's impact on global food production and security, examining the interplay between birth and death rates, and economic systems. The report references the four-stage demographic transition model and explores how improvements in healthcare, education, and family planning can influence crude death and birth rates. Furthermore, it highlights the US model of Global Hunger and Food Security Initiative as a crucial program to address malnutrition and food security in developing countries, aiming to provide access to nutritious food for all, especially the poor and financially vulnerable. The report concludes by emphasizing the need for strategies to reduce hunger and ensure sustainable food systems in a rapidly changing world.

Abstract
The present paper details about the demographic transition model and global food production
with its distribution to the human population growth for meeting world food security goals.
Body of paper
The demographic transition is defined as a transition from the low birth or death rates to high
birth or mortality rates in any economic system. The demographic transition model describes this
transition to foresee how the society will grow if it becomes wealthy. The four stage
demographic model was built by Warren Thompson (1887-1973). The model has a generalized
description of fertility, mortality, and growth rates of society at different times. Four stages are
described in demographic transition model ("Demographic Transition Model," 2017; "PAPP101
- S01: Demography on the world stage", 2017)
1. Pre-transition: It is characterized by high birth and high death rates. Population growth is
kept low by Malthusian preventative (late marriage age) and active checks (war, famine or
drought).
2. Early transition sees the fall in death rates while birth rates remain high. Population size
increases during this phase
3. Late transition notices decline in birth rates with which population growth decelerates
4. Post transition phase is defined by both low birth and death rates. Population grows
negligible and soon enters the decline phase. The population is almost stable here.

In the third phase of demographic transition model, the modern medicine and sanitation methods
has led to the decline in crude death rates and crude birth rates while country population grows
rapidly.
The three conditions of developed world that leads to phase 4 of the transition is the huge
differences in healthcare, wealth and other goods and services with what can be seen in
developing countries. With the improvement in healthcare, education and implementation of
family planning along with employment would lower down the crude death rates and crude birth
rates in developing countries.
The US model of Global Hunger and Food Security Initiative would help in healthcare as the
people would not be much affected by malnutrition. As malnutrition is the major disease factor
in the world.
This program helps in reducing the problems of foods security depending upon country’s need. It
has aim to reduce the chronic hunger, malnutrition and provide food for all poor and financially
weaker sects. The plan sets a guidelines for the developing countries to make sure that all people
including poor are accessible to healthy and nutritious food.
