A. Water Scarcity

Both economically and environmentally, water shortage is becoming a more urgent problem. It is imperative to explore and implement green technologies for water conservation in agriculture to ensure sustainable water resources for rural and urban areas.

For agriculture to guarantee sustainable water resources for both rural and urban areas, green technologies for water conservation must be investigated and put into practice.

Water stress is increasing, especially in places like the American Southwest where estimates by 2030 show previously unheard-of levels of water stress. Ninety percent of water used in the U.S. West goes to agriculture.

Already, states like Arizona, Colorado, and California are struggling to manage the Colorado River’s dwindling water supplies.

Although nations like Israel have effectively desalinated Mediterranean seawater to produce usable freshwater, the United States has not yet fully embraced this technique. Water conservation remains, thus, the best way to deal with water stress in agriculture.

With over 40 American states projecting water shortages by 2024, the U.S. Environmental Protection Agency (EPA) has made clear how urgent water conservation is.

B. Impacting Water Conservation 

State-by-state variations in water conservation laws are striking and cover everything from plumbing requirements to drought contingency plans. Just 11 states—California leading the pack—were rated A or B for both conservation and climate resilience in a 2017 Water Efficiency and Conservation State Scorecard.

The following laws are about to have an effect on agricultural water conservation:

1. Sustainable Groundwater Management Act (SGMA):

2014 saw the passage of SGMA by California, the final state to control groundwater. Local Groundwater Sustainability Agencies (GSAs) are given the authority under this law to manage groundwater use in their own basins.

Farmers will especially need to measure and, in many cases, restrict the amount of groundwater they use for irrigation, hence, SGMA is very significant to them. Groundwater Sustainability Plans (GSPs) adoption in 2020 and 2022 is probably going to result in major changes in conservation methods and the development of smart water markets to enable groundwater trading.

2. Colorado River Compact:

Signed originally in 1922, this compact controls the distribution of water resources in the Colorado River basin. Preempting federal government-mandated limitations, the seven impacted states have agreed to voluntary reduction with water levels in Lake Mead and Lake Powell at historic lows.

This is really a stopgap, though, and by 2026, a new deal needs to be agreed. The region’s agricultural future is yet unknown; Arizona, for instance, has set aside $9 million to assist Pinal County farmers who will need to drill new groundwater wells.

C. Why green technologies in agriculture?

Because they lessen environmental damage, generate fewer byproducts of fossil fuels, and support sustainable agricultural development, green technologies are becoming more and more significant in agriculture.

Green technology in agriculture refers to the use of sustainable practices and technologies to improve crop yields, reduce environmental impact, and promote long-term agricultural sustainability.

There are several reasons why green technologies are crucial in modern agriculture:

1. Benefits to the Environment:

Green technologies reduce the negative environmental impacts of traditional farming methods.They reduce the usage of toxic pesticides and fertilizers, improve soil health, and clean up water. Biodiversity and ecosystems are thus better protected.

 2. Resource efficiency

This is a major emphasis of green farming methods. Drip irrigation is one of the ways they help save water. They also cut energy use and maximize land use. Agricultural activities are guaranteed to be more economical and sustainable by these methods.

3. Climate Change:

Carbon sequestration in the soil is one way that green agriculture helps to slow down climate change. Reduced tillage and cover cropping, for example, help to trap and store carbon dioxide, which lowers greenhouse gas emissions.

4. Higher crop yields:

Several green technologies are intended to raise crop yields, including genetically modified crops and precision agriculture. With the world population still rising, this is essential to guaranteeing food security.

5. Economic viability:

Higher profitability and output in agriculture are frequently the results of green technologies. They lower input costs, strengthen crop tolerance to pests and climate change, and improve farming’s general economic viability.

D. The urgent necessity to give green technology in agriculture top priority

Agriculture has significantly worsened environmental degradation. Massive volumes of fossil fuels are released into the atmosphere during the very carbon-intensive processes of food production, transportation, and consumption, which speeds up global warming.

It is imperative to give green technology in agriculture top priority because of the growing population and rising living standards worldwide.

What are, therefore, the top green technologies in agriculture today?

Using renewable energy, zero tillage, biotechnology, organic agriculture, vertical farming, irrigation monitoring, integrated pest management, drones, fleet management, agricultural robots, and digital sensors, these cutting-edge methods seek to make farming more environmentally sustainable.

E. The Call for Sustainable Agricultural Technologies

Nations worldwide are implementing laws with the goal of ensuring agricultural sustainability, focusing on environmental protection and pollution monitoring. Eutrophication, deforestation, soil erosion, water pollution, and resource exploitation have all been connected to traditional farming methods. These activities have significantly worsened climate change in many countries.

Some farmers continue to use antiquated methods and equipment, such monocropping, which over time depletes soil nutrients. There are also negative environmental effects to clearing forests for agricultural use.

Particularly, the loss of forests is a serious hazard. The absorption and filtering of carbon emissions is mostly dependent on mature trees, whose disappearance contributes to atmospheric deterioration and global warming.

F. Green technologies for water conservation in agriculture: 

1. Renewable Energy

Since renewable energy provides steady, ecologically benign energy, it is essential to sustainable agriculture. The release of greenhouse gases by fossil fuels accelerates climate change.
