How Can Solar Water Pumps Revolutionize Agriculture?
Agriculture is still a significant economic sector around the world. While many agricultural procedures are now automated, some still require physical labor, which makes them laborious and time-consuming. Water pumping is one such procedure that still requires substantial labor to make irrigation possible in fields.
According to the 2015 UN World Water Development Report, groundwater supplies 43% of all irrigation water and at least 50% of the world's population's drinking water. To meet this worldwide need and close the expanding gap between supplies and consumption for different reasons, it is crucial to create new, creative solutions.
Everyone is currently aware of the ominous predictions made by climatic trends. The true tragedy is that most people are unaware that we have already passed the tipping point.
I'll give you a quick case study. Mali, the tiniest landlocked nation in Africa, lost more than half of its total geographical area to desertification in just ten years. According to the UN, 98 % of Mali is under a warning about desertification as a result of both natural and human activities. Not far behind are other African nations. The widespread use of solar energy technology has the ability to change this trend.
There is an urgent need to discover alternatives to the current water pumping procedures because agriculture is such a significant component of the global economy and because irrigation and water from natural sources are used to cultivate half of all food produced today.
The issue is that Africa is starting to experience serious issues related to the energy crisis and other resource conflicts. As a result of the rapid depletion of oil and other unreliable energy sources like coal, the continent is becoming increasingly vulnerable to weak economic growth. Other renewable energy sources, such wind, hydropower, and biomass, have become necessary due to the demand for energy.
As if that weren't enough, smallholder farmers ignore the unpredictable weather and mostly rely on rainwater to irrigate their crops. The absence of rain requires the farmers to employ fossil fuel-powered pumps or hand-operated agricultural irrigation, exhausting them both physically and financially.
Solar energy, on the other hand, is the most abundant energy source on earth and it won't run out for another 500 years. By Solar Water Pumping, it can be drawn from the sun (SWP). Also, a solar water pump can help farmers save their fuel costs by 20 to 50 percent.
Solar water pumping includes moving water to a higher elevation where it can be utilized to irrigate crops by pumping it with the aid of solar pumps.
In other words, raising water out of a borehole and dispersing it over fields can be done with a solar-powered water pumping system (SPWS). It does away with costly maintenance expenses, lowers the possibility of electrical wire failure, lowers the cost of investment for farmers, boosts their profitability, and makes them self-sufficient in food production, thereby eradicating hunger.
One of the numerous affordable and practical solar-powered alternatives is a solar water pump.
Experts estimate that 60% of Africa's arable land is dry. Sadly, droughts and floods are frequent occurrences in many African nations. They have a significant negative impact on smallholder farmers' production, together with other natural reasons. A key technical approach that can assist in resolving these issues is solar energy. Understandably, its potential has piqued elite Africans' interest and motivated them to take action to comprehend and invest in solar water pumping as a bridge towards industrialization.
In essence, solar energy transforms the agricultural industry!
