Although climate change is a global phenomenon, its impacts vary depending on region and season. To formulate appropriate adaptation options and ensure timely responses, we first need to better understand the potential impacts of climate change on maize yield and production, on different spatial and temporal scales.

The state of Haryana, India’s breadbasket, faces a major challenge due to the excessive use of nitrogen fertilizer (N: P: K = 27.2: 9.8: 1) in agriculture. The overuse of nitrogen fertilizer in the rice-wheat systems of Haryana has led to high production costs, low efficiency, environmental pollution and nitrate contamination of groundwater, which causes blue baby syndrome in young children.

A training course on developing stress-resilient maize for early-/mid-career maize breeders from national programs, agricultural universities and seed companies, especially small and medium enterprises (SMEs), was held at CIMMYT-Hyderabad, India, on 15 May 2015. The course was open to partners in the Heat Tolerant Maize for Asia (HTMA) project and members of the International Maize Improvement Consortium (IMIC-Asia). It covered key aspects of precision phenotyping, including enhancing precision of field trials, managing adequate levels of stress to express available genotypic variability, using advanced tools to capture data efficiently and precision in recording various traits in phenotyping trials.

A farm budgeting booklet and training empower women with knowledge so they are able to make decisions and increase their family income.

During Science Week (15-18 June) held at CIMMYT headquarters in El Batán, Mexico, scientists from around the world gathered to share the successes and review the activities of different CIMMYT programs. Attendees sought to find solutions to help meet global food needs related to basic cereals, as well as combat poverty and face the challenges posed by climate change.

The Bangladesh Agricultural Research Institute (BARI) and CIMMYT organized a training course on developing stress tolerant maize at BARI facilities in Gazipur, Joydebpur, Bangladesh, on 21 April 2015. The course, part of CIMMYT’s Heat Tolerant Maize for Asia (HTMA) project supported by the United States Agency for International Development under its Feed the Future initiative, gave maize scientists the opportunity to learn the principles, tools and techniques involved in developing high yielding maize hybrids with enhanced tolerance to major abiotic stresses such as drought and heat, as well as how to effectively deploy them.

CIMMYT’s Heat Stress Tolerant Maize for Asia (HTMA) project held a hybrid maize field day during 21-22 April at the Bangladesh Agricultural Research Institute’s (BARI) Regional Agricultural Research Stations (RARS) in Khoirtola, Jessore and Gazipur. The event was attended by over 60 participants, including local maize farmers, Bangladeshi seed company representatives, agricultural input dealers, Bangladesh government seed system officers and BARI maize researchers.

Project team gathers in Kathmandu to plan for the 2015 monsoon cropping season.

Preliminary results have shown that a maize-coffee cropping system acts like a huge atmospheric carbon sink, capturing up to 60 times more carbon than a coffee-bean system during one cycle of the associated temporary bean crop. In addition, maize creates a more adequate microclimate for coffee’s growth and development because it reduces air temperature, helps to maintain soil moisture and decreases daytime-nighttime soil temperature fluctuations. This has a buffer effect that benefits soil biochemical processes and improves crop productivity.

Sanjaya Rajaram, recipient of the 2014 World Food Prize, told more than 200 participants at the World Food Forum in Santiago, Chile, on 14 April, that he held hopes for a “second Green Revolution.”
