Intensively practices rice-wheat (R-W) cropping system (RWCS) in South-Asia is suffering from many sustainability issues such as micronutrient deficiencies, labour scarcity, production cost, declining land, declining groundwater level and water productivity along with declining soil health. Climate change further complexes the things in one or other way. Therefore, the intervention of climate smart technologies is urgent for improving water productivity in an enormous water use RWCS of South-Asia. Although, farmers are confused regarding picking of suitable climate smart technology (CST) viz., laser land leveling, un-puddled direct-seeded rice (UPDSR), soil matric potential based irrigation, double zero tillage in wheat followed by rice, raised bed planting, short duration cultivars and correct transplantation time, for enhancing their livelihoods through increasing land and water productivity on one side and mitigating global warming consequences on other. Performance of these technologies is both site and situation specific, and care must be taken in practicing them. Most of them cutting down the drainage losses, which further reduces recharging of soil profile which is not required in water stressed regions while these might be termed as energy-saving technologies; otherwise used to withdraw water from the deeper soil depths. These CST are also useful for waterlogged regions. However, CST viz. correct transplantation time and short duration cultivars partition higher fraction of ET water (evapotranspiration) from E (evaporation) to T (transpiration) component which further favour higher grain yields and thus, higher water productivity. Therefore, it is crucial for introduction of CST for improving agricultural and water productivity in the era of climate change in an enormous water use RWCS of South-Asia.

For the first time in history outside of Latin America, deadly wheat blast caused by the fungus Magnaporthe oryzae pathotype triticum (MoT) emerged in the 2015–2016 wheat (Triticum aestivum L.) season of Bangladesh. Bangladesh, a country in South Asia, has a population of nearly 160 million, of which 24.3% are classified as poor. Consequently, malnutrition and micronutrient deficiency are highly prevalent, particularly among school going children and lactating women. Bangladesh Wheat and Maize Research Institute (BWMRI), with the technical support of the International Maize and Wheat Improvement Center (CIMMYT), Mexico, has developed and released a new wheat ‘BARI Gom 33’. The new wheat is a zinc-enriched (Zn) biofortified wheat, resistant to the deadly wheat blast disease. ‘BARI Gom 33’ provides 5–8% more yield than the check varieties in Bangladesh. Rapid dissemination of it in Bangladesh, therefore, can not only combat wheat blast but also mitigate the problem of Zn deficiency and ensure income for resource-poor wheat farmers. Importantly, a large portion of the current wheat area in India and Pakistan is vulnerable to wheat blast, due to the similarities of the agro-climatic conditions of Bangladesh. As wheat blast is mainly a seed-borne disease, a rapid scaling out of the new wheat in Bangladesh can reduce the probability of MoT intrusion in India and Pakistan, and thereby generate positive externalities to the food security of more than 1 billion people in South Asia. This study explains the development process of ‘BARI Gom 33’; the status of malnutrition in Bangladesh, and the possible economic gain from a rapid scaling out of ‘BARI Gom 33’ in Bangladesh. A few policies are recommended based on the discussions.

The World Health Organization (WHO) has estimated that around 2 billion people across the globe are suffering from “hidden hunger”, where 815 million are under malnutrition. The major essential elements for humans are Fe, Zn, I, Se, Ca, F, and also vitamins. Among them, Zn is considered in the fifth place leading to causes of several deficiency diseases. At least one-third of the population in the world is facing Zn deficiency including around 450,000 children under the age of five. Vitamin A, Fe, and Zn deficiencies can be overcome through the biofortification of staple foodstuffs. This review emphasizes various breeding and agronomic approaches for the biofortification of Zn in wheat grains, which is an encouraging and cost-effective method to enhance the Zn contents of cereal grains. Recently, the Bangladesh Wheat and Maize Research Institute (BWMRI), with technical support from CIMMYT, Mexico, released a promising new Zn-biofortified wheat cultivar, ‘BARI Gom 33’, a result from a conventional breeding program. It has 32 and 50–55 mg kg−1 Zn without and with soil application of ZnSO4, respectively. This cultivar could be a savior for a million people in South Asia, including Bangladesh.
