Cassava’s outrageous intensity as 21st Century crop

28 May 2013, RomeSave and Grow, an environmentally-friendly husbandry indication promoted by FAO, can sustainably boost cassava yields by adult to 400 percent and assistance spin this tack from a bad people’s food into a 21st Century crop,  FAO pronounced today.

In a newly-published margin beam detailing Save and Grow’s applications to cassava smallholder production, FAO remarkable that tellurian cassava outlay has augmenting by 60 percent given 2000 and is set to accelerate serve over a stream decade as policymakers commend a outrageous potential.

But regulating a inputs-intensive proceed pioneered during final century’s  Green Revolution to boost cassava prolongation risks causing serve repairs to a healthy apparatus bottom and augmenting a hothouse gas emissions obliged for meridian change.

The solution, says FAO, lies in a Save and Grow proceed that achieves aloft yields with softened dirt health rather than with a complicated use of chemical inputs.  Save and Grow minimizes dirt reeling caused by required husbandry such as ploughing, and recommends progressing a protecting cover of foliage over soil.

Instead of a monocropping routinely seen in complete husbandry systems, Save and Grow encourages churned gathering and crops rotation, and predicates integrated harassment management, that uses disease-free planting element and pests’ healthy enemies to keep damaging insects down,  instead of chemical pesticides.

Spectacular results

The proceed has yielded fantastic formula in trials orderly in Viet Nam, where farmers regulating a softened technologies and practices increasing cassava yields from 8.5 tonnes to 36 tonnes  — an boost of some-more than 400 percent.

In a Democratic Republic of Congo, by training in a use of healthy planting materials, mulching and intercropping,  farmers attending margin schools achieved furnish increases of adult to 250 percent.

In Colombia, rotating cassava with beans and sorghum easy yields where vegetable manure alone had failed.

Cassava is a rarely versatile stand grown by smallholders in some-more than 100 countries. Its roots are abounding in carbohydrates while a proposal leaves enclose adult to 25 percent protein, and iron, calcium and vitamins A and C.  Other tools of a plant can be used as animal feed, and stock lifted on cassava have good illness insurgency and low mankind rates.

One reason pushing augmenting direct for cassava is a stream high turn of cereal prices. This creates it an appealing choice to wheat and maize, quite as cassava can be processed into a high-quality flour than can partially surrogate for wheat flour.  

Food security

But, together with a significance as a source of food and food security, cassava also has a operation of industrial uses that give it outrageous intensity to coax farming industrial growth and lift farming incomes.

Cassava is second usually to maize as a source of starch and recently-developed varieties furnish base starch that will be rarely sought after by industries.
Demand for cassava as a feedstock for a make of bioethanol is also flourishing rapidly.

Another critical care is that of a vital tack crops in Africa, hardy, volatile cassava is approaching to be a slightest influenced by advancing meridian change. 

With Save and Grow developing countries can so equivocate a risks of unsustainable intensification while realizing cassava’s intensity for producing aloft yields, alleviating craving and farming misery and contributing to inhabitant mercantile development.
