Susan George (1976) states “The food crisis became the focus of worldwide attention in 1974.” By calculating lack of food, the maximum dominance is in sub-Saharan Africa, there is one in every three persons is hunger, but the ultimate amounts are in South and East Asia. Availability of food is the greater problem for them, than the supply of food (FAO, 2011).
This figure illustrates the ratio of hunger people over the world (FAO, 2011).
In this topic, we are going to discuss the situation in Sub-Saharan Africa especially South Africa. South Africa consists of thirteen countries, including the islands (The National English Literary Museum, 2010). Amongst the many reasons for this situation, bad harvest is the main cause of decreasing food storages in South Africa which is due to is the shortage of nutrients in the soil. In order to alleviate the hunger problem in South Africa, the government uses many solutions, such as replenishment of soil fertility (Sanchez 2002, 2019). For the purpose of this project: variety of soil nutrients and methods of its replenishment will be discussed. This project will argue that improvement of soil by different kinds of nutrients is successful solution and will evaluate it using three criteria: profitability, costs and time.
There are many reasons of nutrient depletion of soil in South Africa, but a few ways to get success and they are: phosphorus replenishment, nitrogen replenishment and use of animal manures. Discuss of these three ways are followed in next three paragraphs.
Sanchez et Al. (1997, 12) state that phosphorus is one of the most main segments of soil productivity in South Africa. Work done by phosphorus is complex, because of chemical and biological route, and has enduring propert...

Africa has a regular coastline characterized by few indentations. Because of the smooth coastline, natural harbors were non-existent. Today, however, there are important coastal cities, such as Lagos and Dakar. With the exception of the Mediterranean coast, most of the coastline is low-lying , generally narrow and rising sharply to high elevations. The African climate and topography varies greatly. Although temperatures are usually high, due to being so close to the equator, rainfall, soil quality and elevations are of various degrees. Because most of the African continent has not been covered by water for millions of years, soils have developed according to their weathering e...

There are many problems confronting our global food system. One of them is that the food is not distributed fairly or evenly in the world. According “The Last Bite Is The World’s Food System Collapsing?” by Bee Wilson, “we are producing more food—more grain, more meat, more fruits and vegetables—than ever before, more cheaply than ever before” (Wilson, 2008). Here we are, producing more and more affordable food. However, the World Bank recently announced that thirty-three countries are still famine and hungers as the food price are climbing. Wilson stated, “despite the current food crisis, last year’s worldwide grain harvest was colossal, five per cent above the previous year’s” (Wilson, 2008). This statement support that the food is not distributed evenly. The food production actually increased but people are still in hunger and malnutrition. If the food were evenly distributed, this famine problem would’ve been not a problem. Wilson added, “the food economy has created a system in w...

This directive addressed the major threats to soil, such as the preservation of soil functions, the prevention of soil degradation (loss of biodiversity and organic matter), limit the concentration of dangerous substances that could harm humans and the environment (contamination), reducing erosion, and remediating contaminated and degraded sites (9, 15). Regarding soil organic matter content for example, carbon is lost when grasslands or forests are converted into croplands and vice versa, proper management and constraints have to be put into place in order to mitigate the losses (17). Another major issue is the interrelationship between the soil and climate change; with improper land use too much carbon dioxide is released into the atmosphere, this speeds up climate change, which in turn will increase carbon dioxide discharge, creating a viscous
Crops such as cotton became such a lucrative product that farmers that grew food for the communities began to grow these “cash crops” instead. With food crops decreasing famine became a real threat in parts of South Africa.
Food insecurity defined, is ‘the state of being without reliable access to a sufficient quantity of affordable, nutritious food’ (Oxforddictionaries.com, 2014). This in turn leads to hunger, which can have three possible meanings; 1) ‘the uneasy or painful sensation caused by want of food; craving appetite, also the exhausted condition caused by want of food’, 2) ‘the want or scarcity of food in a country’, and 3) ‘a strong desire or craving’ (Worldhunger.org, 2014). Food insecurity also leads to malnutrition, with 870 million people in the world or one in eight, suffering from chronic undernourishment (Fao.org, 2014). From this alarmingly high figure, 852 million of these people live in developing countries, making it evident that majority of strategies used to solve this problem should be directed at them (Fao.org, 2014). The world produces enough food to feed everyone, with an estimated amount of 2,720 Kcal per person a day (Worldhunger.org, 2014). The only problem is distri...
Soil remediation is part of a broader effort known as environmental remediation. It restores previously contaminated land to an uncontaminated state and is an important part of sustainable development, especially in respect of resource management and reducing reliance on landfill (Scottish Environment Protection Agency, n.d., p. 4). Most countries around the world are actively engaged in some form of soil remediation. Each year in the European Union, several billion euros are expended on the remediation of land affected by contamination. It is important that this money is spent intelligently and appropriately (Elorriaga, 2014, p. 2).

Farmers apply nutrients such as nitrogen, phosphorus, manure, and potassium in the form of fertilizers to produce a better product for the consumers. When these sources exceed the plants needs or if these nutrients are applied before a heavy rain then the opportunity for these excess to wash into aquatic ecosystems exists.
Soil composition is a two way, dirt road. It gives what it takes and vice versa.
