We’re getting hit harder by drought. Doing the usual things for drought-proofing no longer seems enough.

Change is essential – the challenge is to what extent? While no one can blame us for being cautious, we need to challenge our thinking by asking ourselves, “what’s the best thing we can do?”

Fortunately, there are Farmers leading the way in Drought-Proofing…

… And they are getting heartening results despite farming in marginal land.

These farmers were willing to make radical changes because their situation was urgent. They didn’t have the luxury of making changes they hoped would be enough. With no government assistance and low-interest loans – their lives, as well as their livelihoods, were threatened. Arguing that they lacked sufficient funds, time or the necessary equipment and machinery to drought-proof their farms was not an option.

How do Farmers do Drought-Proofing?

Growing trees. Yes, it’s that simple.

Like many marginal rainfall areas, the southern edge of the Sahel desert in Africa had been open woodlands – scattered trees and shrubs. Massive tree clearing happened from the 1960s for firewood, and because farmers were told that trees consumed precious water and nutrients that would otherwise be available for their crops and pastures.

Over the last twenty years, families have revegetated five million hectares of farmland, increasing their incomes by strategically planting and allowing the natural regeneration of trees within their pastures, arable fields and vegetable plots.[i]

Why do Trees make such a difference for Drought-Proofing?

Trees store water, create shade, reduce wind, air temperatures and therefore the amount of water lost from the soil through evaporation. But, as explained in ‘Drought-Proof your Farm’ and the ‘Eco-logical Farming Handbook, growing trees and other extra vegetation, we dramatically increase the amount of rainwater infiltrating and stored in our soil. Research demonstrates that something as simple as planting trees in paddocks increases water infiltration three-fold.[iii]

Growing Vegetables under Trees in Africa

In ‘growing up’ – using the vertical space we have available – we create opportunities to grow extra forage and emergency stock feed for livestock and, like the African farmers, create additional income streams by selecting tree species producing fruit, nuts, seeds, construction timber, pollen, nectar for bees, etc.

We also reduce flooding, sequestrate more carbon in our soil and vegetation, and increase rainfall. Yes, it’s true. We now have evidence that when we grow more trees, rainfall increases!

On our farm in far north Queensland, we’re seeing the benefits of combining Holistic Planned Grazing with Silvopasture and tree alleys for windbreaks. The grass under the trees stays green longer into the dry season and continues to photosynthesise later in the morning than grass growing in the full sun. In the bananas and orchard, we’re using an overstory of open-canopied legume trees to provide ‘protective cropping’ by reducing sunburn on our fruit.

What’s Critical to Realise

1. Improving the condition and number of shelterbelts, patches of remnant vegetation, riparian and other natural vegetation help, but these actions on their own are not sufficient. We need to skillfully plant and allow the natural regeneration of trees within our pastures, arable fields and market gardens, and develop other ways to grow more plant biomass using practices like polycultures, alley cropping, cover crops, living mulch, and green manure.

2. Warmer (and wetter) your climate, the vegetation biomass needed. That’s why – silvopasture, the raising of animals among trees, is ranked across Africa, Asia and South America as the most important climate-smart intervention graziers can make.[v] Arable farmers and horticulturists in these regions are also starting to grow cereals and veggies using agroforestry designs.

3. It isn’t easy to maintain grass cover under trees using set-stocking or rotational grazing, as the grass gets continuously trampled by livestock camping under the trees. Mob grazing techniques like Holistic Planned Grazing allow grass to recover.

Getting Practical

By asking, “what’s the best thing I can do to drought-proof my farm?” you’ll do the major re-think necessary to take you beyond hoping that what you do will be enough.

Start small by trialling techniques to see what works best. Get your seeds, seedlings and planting materials ready for when the rain does come.

In Niger, farmers convert approximately 250,000 hectares each year, despite getting little or no rain. By controlling grazing, tree suckers grow up to 2m within the first year, and within 2-3 years, the trees are 4 to 5 m high.[x] In areas where farmers can’t rely on natural regeneration or want to grow particular species, they plant seeds and young trees.Digging holes for trees for drought-proofing land in Niger
