The theme of the World Environment Day on 5 June 2015 was (seven billion dreams for one planet, Let’s consume carefully), and a new report by the United Nations confirmed how the world can avoid the financial and environmental costs of resource depletion and how millions could be saved on the World Environment Day. In our opinion, the best ways start with developing Early Warning Systems (EWS) and climate prediction, than with the onset of the financial and environmental costs of the effects of resource depletion on economic growth, so the countries need to find ways to manage the limited resources with the needs of the urban world’s ever-increasing population.
In 2010, the governments agreed on the need to reduce greenhouse gas emissions in order to reduce the high temperatures on a global scale in the range of two degrees Celsius. With the temperature’s increase at a rate of 2 percentage, significant changes might take place in the climate, which begin with drought, that in turn leads to a decrease in the total value of agricultural output and income in general, which delays the growth of the national economy. Drought leads to food shortages and famine, causing the displacement of the population from the drought-affected areas to the big cities, in search of food and work, which increases the pressure on natural resources, causing major social problems, including random housing and an increase in the amount of waste growth.
Farmers, livestock owners, and others secure the production requirements before the start of the rainy season in general, so when cultivating the crop, the farmer decides what is the type he is going to plant, the appropriate date for planting, along with the rate of seeds, and the amount of fertilizers before the start of the rainy season and before he knows the amount of rainfall and its distribution.
The Early Warning System capability represents a powerful tool to avoid several costs associated with the wrong distribution of resources, especially if it was accompanied by a good agricultural system.
The reliable early warning system enables governments and relief organizations to prepare more efficient interventions annually, so it is necessary to develop Early Warning Systems, along with drought forecasting systems, and documenting information for different partners to prepare for facing the drought, and this could happen by identifying the needs of the air monitoring networks, remote sensors, along with providing data storage and analysis, as well as Geographic Information Systems (GIS) and disseminating this information, and there are many examples on this in the African continent.
