Farming Innovations Help Farmers During Dry Times
As the weather changes more and more, droughts are getting worse all over the world. Farmers are trying to find ways to deal with this so they can still grow food and make a living. They're using new ideas, like finding plants that can handle dry conditions better, bringing back old types of crops, and using clever ways to save water. It's a fight against drought that's full of new ideas, science, and being able to change what you do.
Droughts Are Getting Worse
Many small farmers live in dry areas where it doesn't rain very often. These places usually get less than 18 inches of rain each year, the temperature can get above 86°F, and the growing season is short, only about 80 to 95 days. The changes in our climate have made things worse, with rain coming late or not at all when crops need it most.
This is a big issue. In places like the Sarigol Afsar Dam Basin in Türkiye, if farmers keep growing crops the way they always have, they'll need a lot more water for irrigation – maybe 18 to 26 per cent more, depending on how the climate changes. In Africa, droughts happen so often that they affect about 160 million acres of land each year, which puts many people at risk of not having enough food.
Tiny Things, Big Help
Scientists are looking into new stuff that can help crops survive when it's dry. A study in Environmental Science: Nano says that things like carbon dots, graphene oxide, and carbon nanotubes can help plants grow better.
These particles work in different ways. When there's a drought, they help plants keep water in their leaves, move water around better, and protect themselves from damage. They also help with photosynthesis, which is how plants make food, and boost their defences.
If you soak seeds in these materials before planting, it can help them start growing strong, even if there's not much water. This can help us reach goals like ending hunger and taking action on climate change. But the study also says we need to learn more about how these materials affect the environment and find ways to make them cheap enough to use.
Watering Plants Just Right: Using Pictures Instead of Guessing
Scientists at the International Potato Center (CIP) have found that taking pictures can change how farmers water their crops. By using special cameras that can see how hot the potato leaves are, they can tell exactly when the plants need water.
They did studies in Peru with a type of potato that can handle dry conditions. They found that they could use a lot less water with both regular and drip watering systems and still get a good amount of potatoes. The trick is to water the plants just enough to keep them from getting too stressed so they can produce well and save water.
David Ramirez, who leads CIP's Crop Ecophysiology and Modelling Laboratory, says that this idea can be used to check how any technology works. Besides watering, it can also help with breeding new types of plants, managing seed systems, and other farming practices.
You could even use cameras on drones or satellites to do this over large areas, which could really change how we water crops. This is important because potatoes are the third most important crop in the world, and they give you more energy for the amount of water you use than rice, corn, or other main foods.
Old Ideas Can Be New Again: Using Long-Lasting Crops to Fight Drought
Sometimes, the best ideas are old ones. In the dry highlands of Southwest Ethiopia, farmers have always grown enset, a plant that lives for a long time and is known as the tree against hunger. Studies show that farmers are growing more enset because of drought, and it seems to be a good idea.
A look at crop production and climate data shows that the areas that have more severe droughts also have more land growing enset. The drier it gets, the more enset farmers plant.
Enset is great because you can harvest it when you need it, it produces a lot of food, it can be stored for a long time, and it doesn't need much water. Its roots can reach water that other crops can't. After a long drought, people prefer crops like roots and tubers that can be stored, so farmers are turning to these long-lasting crops as a way to deal with climate change.
Different Crops: Planning for Different Amounts of Rain
Studies from Türkiye suggest that growing a mix of crops can reduce how much water you need. In the Sarigol Afsar Dam Basin, where grapes are common, scientists figured out how much water would be needed for irrigation if the climate changes.
If they keep growing only grapes, they'll need about 18 to 26 per cent more water. But if they switch to growing 40 per cent grapes and 60 per cent olives, they can keep the increase down to about 12 to 16 per cent.
This idea uses computer models and climate to help plan irrigation and protect water supplies for the future.
Crops That Can Handle Tough Conditions: Breeding for Drought Resistance
In Africa, scientists are working on computer models for crops that don't get much attention but could be really helpful for dealing with climate change. These include grains, beans, oilseeds, roots, tubers, and vegetables that can do well even when it's dry.
A project called BECAR-Africa Arabia is working on wild sorghum, which has genes that can help it survive in dry conditions. By using studies that created new types of sorghum, they're moving those genes into types of sorghum that farmers already grow.
Wild sorghum has evolved to survive in tough environments, so it has characteristics. By moving those characteristics into varieties, researchers hope to create farms that produce a lot of food and connect markets in East Africa and the Arabian Peninsula.
Protecting Soil and Water: Ideas That Work
A look at different farming practices shows that combining different ideas can really help. Using water, protecting the soil, and growing crops like sorghum in dry areas has increased harvests from 200 to 1,140 kg per hectare in Zimbabwe and from 250 to 5,675 kg per hectare in Kenya.
These practices include things like collecting rainwater with ridges and pits, using little or no-till farming, leaving crop residue on the field, combining trees with crops, and adding things like biochar and fertiliser to improve the soil and help it hold water.
Biochar, which is made from waste, makes the soil less dense, helps it hold more water, and creates a better environment for crops to grow. Using it with vermicompost can increase how porous the soil is from 20 per cent to 60 per cent while making it less dense.
New Ideas: Helping Trees Survive Drought
In Zambia, women farmers are using a new idea to fight drought that increases how many tree seedlings survive in dry conditions.
The UNDP is testing this. So far, they've planted 1,500 seedlings of eight types of trees, and 1,000 of them have sprouted. It manages different types of trees, which helps protect biodiversity and improve chances.
Women are learning new skills along with these methods, and they're involved in everything from planting. The producer's cosmetic products from ingredients, turning equipment into oils.
The Main Thing: Education and Usage
Even with all these new ideas, it's important for farmers to know about them and use them. Many farmers haven't been taught about climate-smart farming practices, and they see them as just another government programme.
Researchers say that it's to have programmes that teach farmers about these technologies. Combining new ideas with programmes and making sure women have access will be for building resilience.
The fight against drought is happening everywhere, from labs to nurseries, from banks of species to farmers' crops. One thing that connects all these areas is the understanding that dealing with climate change means using new tools.
The offer chances for farming to adjust to changing conditions. Carbon materials and thermal helping survive show the creativity in the challenge.
Yet it is not. Success needs steps that combine crops with regulation, soils with. It needs that farmers need it and investment in the study that will produce the innovations.
For farmers whose livelihoods depend on rainfall that no longer comes, any advances are welcome. They exist. The now is putting them to.
