Dynamics in food production and population do not differ to a great extent. The two facets can be considered to be directly proportional in the sense that the presence of plenty food means an increase in the population. In this sense, an increase in the carrying capacity causes a positive trigger to the population. On the contrary, decrease of food means hunger will starve the population and apart of the population will die hence decreasing their population. Arguably, food is a common variable that affect the population.
Throughout the agricultural revolution, it is indisputable that it is human culture that we increase food production to feed the rapidly growing human population (Singh, 2009). However, this is a thermo-dynamic concept because the theory mandates that without enough food the population would not be growing. Also, we maintain the notion that we increase food production to help the malnourished and the starving population. This notion emerges as a result of empathy by the privileged people in society who sympathize with those people starving and malnourished in the society therefore they intervene to contain the situation.
The point is population will not be growing without enough supply of food. And, without increasing food production the human population will continually reduce because most of the population might become distinct due to harsh survival conditions (Nwajiuba Nwosu & Ejiogu 2008).
Global climate change has a great influence on the present and future human life. Climate change has a huge impact on the shift on agricultural production. Especially the agricultural food production is immensely affected by climate change. The variation of physical conditions like temperature and moisture, ultra violet radiations are major determinants of food production (Goklany, 2007).
Climate change is likely to result to the decline of food production as a result of increased drought in most regions of the world. Research shows that by 2030 the effect will be more profound and will reduce pasture and crop yields immensely (Goklany, 2007). According to the forecast, the production of wheat in Brazil will reduce by 14% as a result of climate change.
Notably, rapid climate change can affect agricultural production and biodiversity. Unless the climate change is slow, agricultural production will be affected severely. For instance, if the climate change is slow agricultural research institutions will have time to find remedies for the changes at the same time the agricultural crops to adapt to the climate change. However, if the problem of climate change is left to expand, it will cause a threat to those societies that lack the capacity to mitigate the situation.
Sphere minimum guidelines are core principles that serve as a guideline to humanitarian actors, NGO, and donor institutions that depict that those people affected by calamities have a right to get assistance from the existing humanitarian actors.
The sphere standards help humanitarian workers to have a recap of the qualitative and quantitative indicators that help them to determine how humanitarian agencies should work with communities in the sector of health, food, shelter, and water and sanitation. Basically, the sphere act as a tool for advocacy in with other local authorities, it established the minimum standards or privileges refugees are entitled, and finally provide a guideline how various agencies should deliver their services to the community.
The well being, protection, and support of a pregnant mother and the infant are the core practices to meet the nutritional needs of the infant. Interventions are meant to control artificial feeding to ensure safe feeding practices are embraced. Some feeding practices on infants increase their vulnerability to diseases and even death. Therefore, incorporating practices that do not put the lives of the infants at risk is the core measure to prevent infant morbidity and support the nutritional needs of the infant.
Aggregate demand curve is a force that determines the average quantity to food that is demanded by the economy (Van & Ligthelm, 2009). It is derived by three major factors; the price and income of the food. If the quantity of food demanded is high we expect a proportionate decrease in the price of the same commodity. On the other hand, if the quantity supplied is low, the price is likely to shoot. Therefore, the effect of aggregate demand is realized when the forces of demand are trying to establish an equilibrium.
Income elasticity of demand precisely shows a reflection on how a slight change of income affect the demand of a product. Income is a great determinant of consumer demand. Therefore, a positive change of income leads to a positive change on demand. On the other hand, a decrease of income causes a decrease of the quantity demanded. The rules applies to higher income households in the sense that they high income household have a high propensity of spending hence they tend to have a high demand for various goods. On the other hand, low income households have a low propensity to spending because their reduce their budget to suit the little income hence their demand for goods is likely to be lower than those of high income households. Therefore for income elasticity differs between the two in the sense that the curve for the high income households tend to be more slightly ahead of the curve of low income households. The latter comes behind the high income households curve.
The establishment of genetically modified foods and application of climate smart agriculture are the latest innovations that have been realized to be the cure for food security. The contribution of genetically modified crops has been significantly noted has the best remedy to lack of foods in almost all parts of the world. In a practical manner, in Australia since 1996, GM crops have increased income up to $885 million (Uphoff, 2002). This innovation has come along with techniques like practicing crop rotation during spring and winter has been a productive way in Canada to deal with the stress of moisture variations while planting wheat. Furthermore, there is appropriate technology in place to control pests that has contributed to high productivity in most regions in the world.
Climate smart agriculture has come along with the improvisation of drought resistant crops, crop breeding, mechanization of firms, improving crop varieties, and irrigation has contributed to food security (Rosen, 2014). For instance, the introduction of firm machinery tools has boosted productivity and encouraged large scale farming. In the long run, food production is in plenty to sustain the existing and growing generation. All this innovations are meant to deal with future calamities like food crisis and ways to cope with climate change.
