Ten Lessons from Biotechnology Experiences in Developing Countries

The Asian Biotechnology and Development Review has published an article, "Ten Lessons from Biotechnology Experiences in Crops, Livestock, and Fish for Smallholders in Developing Countries." Written by James D. Dargie, John Ruane, and Andrea Sonnino, the article is a project by the Food and Agriculture Organization of the United Nations (FAO). 
The FAO commissioned a unique series of 19 case studies where agricultural biotechnologies were used to serve the needs of smallholders in developing countries. Most involved a single crop, livestock or fish species and a single biotechnology. From the case studies, ten general and interrelated lessons were drawn that could be used to inform and assist policymakers when deciding on potential interventions involving biotechnologies for smallholders.
Some of the lessons are:
  • the need for government commitment and backing from donors and international agencies;
  • the need for partnerships, both nationally and internationally, but also with the farmers themselves; and,
  • the recognition that long-term investments in science and technology are critical, as is the appropriate integration of biotechnologies with science-based and traditional knowledge.
The study also found that planning, monitoring, and evaluation of biotechnology applications was weak and should be strengthened.

ISAAA Brief 46-2013: Top Ten Facts

ISAAA releases Top Ten Facts about Biotech/GM Crops in 2013, a Special Edition of Crop Biotech Update March 5 issue. We encourage you to translate and/or use the information therein to develop news articles for publication in tri-media in your own country, with proper attribution to ISAAA.

FACT # 1. 2013 was the 18th year of successful commercialization of biotech crops.

Biotech crops were first commercialized in 1996. Hectarage of biotech crops increased every single year between 1996 to 2013, with 12 years of double-digit growth rates, reflecting the confidence and trust of millions of risk-averse farmers around the world, in both developing and industrial countries. Remarkably, since the first plantings in 1996, an unprecedented cumulative hectarage of more than1.5 billion hectares have been successfully cultivated, an area that is 50% more than the total land mass of China or the United States.

FACT # 2. Biotech crop hectares increased by more than 100-fold from 1.7 million hectares in 1996, to over 175 million hectares in 2013.

This makes biotech crops the fastest adopted crop technology in recent times – the reason – they deliver benefits. In 2013, hectarage of biotech crops grew by 5 million hectares, at an annual growth rate of 3%. It is important to note that more modest annual gains, and continued plateauing, are predicted for the next few years due to the already optimal (between 90% and 100%) adoption rates for the principal biotech crops, leaving little or no room for expansion.

FACT # 3. Number of countries growing biotech crops and stacked traits.

Of the 27 countries which planted biotech crops in 2013, 19 were developing and 8 were industrial countries. Stacked traits occupied 47.1 million hectares, or 27%.

FACT # 4. For the second consecutive year, in 2013, developing countries planted more hectares than industrial countries.

Notably, developing countries grew more, 54% (94 million hectares) of global biotech crops in 2013 than industrial countries at 46% (81 million hectares). Successful public/private partnerships were established by several countries including Brazil, Bangladesh and Indonesia.

FACT # 5. Number of farmers growing biotech crops.

In 2013, a record 18 million farmers, up 0.7 million from 2012, grew biotech crops – remarkably over 90%, or over 16.5 million, were small resource-poor farmers in developing countries. Farmers are the masters of risk-aversion and improve productivity through sustainable intensification (confining cultivation to the 1.5 billion hectares of cropland and thereby saving the forests and biodiversity). In 2013, a record 7.5 million small farmers in China and another 7.3 million in India, elected to plant more than 15 million hectares of Bt cotton, because of the significant benefits it offers. In 2013, almost 400,000 small farmers in the Philippines benefited from biotech maize.

FACT # 6. The top 5 countries planting biotech crops – deployment of the first drought tolerant maize and stacked HT/IR soybean.

The US continued to be the lead country with 70.1 million hectares, with an average ~90% adoption across all crops. Importantly, the first biotech drought tolerant maize was planted by 2,000 US farmers on 50,000 hectares. Brazil was ranked second, and for the fifth consecutive year, was the engine of growth globally, increasing its hectarage of biotech crops more than any other country – an impressive record increase of 3.7 million hectares, up 10% from 2012, reaching 40.3 million hectares. Brazil also planted the first stacked HT/IR soybean in a record-breaking 2.2 million hectare launch, and its home-grown virus-resistant biotech bean is ready for commercialization. Argentina retained its third place with 24.4 million hectares. India, which displaced Canada for the fourth place had a record 11 million hectares of Bt cotton with an adoption rate of 95%. Canada was fifth at 10.8 million hectares with decreased plantings of canola but maintained a high adoption rate of 96%. In 2013, each of the top 5 countries planted more than 10 million hectares providing a broad, solid foundation for future growth.

FACT # 7. Status of biotech crops in Africa.

The continent continued to make progress with South Africa benefiting from biotech crops for more than a decade. Both Burkina Faso and Sudan increased their Bt cotton hectarage by an impressive 50% and 300%, respectively, in 2013. Seven countries (Cameroon, Egypt, Ghana, Kenya, Malawi, Nigeria and Uganda) conducted field trials, the penultimate step prior to approval for commercialization. Importantly, the WEMA project is scheduled to deliver the first biotech drought tolerant maize to Africa in 2017. The lack of appropriate, science-based and cost/time-effective regulatory systems continues to be the major constraint to adoption. Responsible, rigorous but not onerous, regulation is needed, particularly for small and poor developing countries.

FACT # 8. Status of biotech crops in the EU.

Five EU countries planted a record 148,013 hectares of biotech Bt maize, up 15% from 2012. Spain led the EU with 136,962 hectares of Bt maize, up 18% from 2012 with a record 31% adoption rate in 2013.

FACT # 9. Benefits offered by biotech crops.

From 1996 to 2012, biotech crops contributed to Food Security, Sustainability and the Environment/Climate Change by: increasing crop production valued at US$116.9 billion; providing a better environment, by saving 497 million kg a.i. of pesticides; in 2012 alone reducing CO2 emissions by 26.7 billion kg, equivalent to taking 11.8 million cars off the road for one year; conserving biodiversity by saving 123 million hectares of land from 1996-2012; and helped alleviate poverty for >16.5 million small farmers and their families totalling >65 million people, who are some of the poorest people in the world. Biotech crops are essential but are not a panacea and adherence to good farming practices such as rotations and resistance management, are a must for biotech crops as they are for conventional crops.

FACT # 10. Future Prospects.

Cautiously optimistic with more modest annual gains expected due to the already high rates of adoption (90% or more) in the principal biotech crops in mature markets in both developing and industrial countries. Bangladesh, Indonesia and Panama approved biotech crop planting in 2013 with plans for commercialization in 2014.

Peanut Gets an Upgrade Against Drought and Salinity

Peanut (Arachis hypogaea L.) is one of the economically important oil and food crops. Peanut is generally grown across a wide range of environments including rain-fed conditions. Because of this, drought is a main limiting factor to peanut production in the semi-arid areas. The development of salinity and drought stress-tolerant peanut to exploit the drought-prone and salinity-affected areas of the world has been imperative these past years. Now, mannitol may just be the thing that would make it a reality.
Mannitol accumulation in most plants works for the alleviation of salinity and osmotic-induced stresses. However, it is not naturally synthesized in peanut. The mtlD gene (from Escherichia coli) codes for an enzyme that converts fructose 2 with 6-phosphate to mannitol1-phosphate. Peanuts transformed with mtlD were evaluated for salinity and drought stress tolerance. The overexpression of the mtlD gene translated to the transgenic peanuts' improved tolerance to salinity and drought. This was revealed by better growth and physiological parameters like mannitol content, total chlorophyll content, and relative water content in transgenic peanuts.
The better performance of the transgenic plants was attributed to the stress-shielding role of mannitol. However, the mtlD expression causing the activation of other protective reactions in transgenic peanut may also be possible

Punctured-hypocotyl Method of Agrobacterium-mediated Transformation

Tomato productivity has always been constrained because of abiotic stresses. Transgenic tomatoes are presently being developed to minimize these losses due to abiotic stresses. Agrobacterium-mediated transformation is the most common approach to producing transgenic tomato. However, the effectiveness of the present methods were limited to only a few tomato cultivars. Hence, we still need an appropriate, simple and general procedure effective across all cultivars. Wounding methods, such as puncturing with a syringe needle, may just be the answer.
Using Indian tomato hypocotyl explants, the efficiencies of the punctured-hypocotyl method as well as normal immersion method of Agrobacterium-mediated transformation were compared. All factors influencing transformation efficiency, such as Agrobacterium density and co-cultivation time, were optimized. The transgene integration of the tomato genome was confirmed by PCR and Southern hybridization. Transformation efficiency was found to be greater with the punctured-hypocotyl method compared to the normal immersion method.
This newly developed method is simple, efficient and could be used to transfer important agronomic genes into the tomato genome for the potential improvement in terms of quality and quantity.
