Response of African sorghum genotypes for drought tolerance under variable environments

New drought-resistant sorghum varieties bring hope for farmers in Africa

Scientists have identified drought-resistant, high-yielding sorghum genotypes that have the potential to revolutionize agriculture in dry regions of Africa. Sorghum, a staple food for millions in sub-Saharan Africa, has long been threatened by devastation from drought.

But now, researchers from the African Centre for Crop Improvement, the Institute of Agricultural Research (IAR), the International Maize and Wheat Improvement Center (CIMMYT), and the University of Life Sciences have discovered genetic resources that thrive under adverse conditions, yielding promising results and providing hope for a future that is more sustainable.

The study looked at 225 sorghum genotypes in various conditions, including non-stressed conditions and pre- and post-anthesis drought stress. The researchers used advanced statistical analysis, such as the additive main effects and multiplicative interaction (AMMI) method, to identify the most resilient and high-yielding genotypes.

The results revealed a vast diversity in the genetic resources of sorghum and provided a pathway for selecting promising genotypes for regions prone to drought. In addition, the study highlighted the significant impact of environmental conditions on grain yield, with genotypes showing variable responses to different growing environments.

For example, genotypes G144 (Kaura Short Panicle-1) and G157 (Kaura Mai Baki Kona) displayed higher grain yield in drought-stressed environments and were among the top performers. Not only do these genotypes outperform registered cultivars, but they also possess traits valued by farmers, making them ideal candidates for future breeding programs. In addition to drought tolerance, genotypes G119 and G127 displayed remarkable stability and high yield under non-stressed conditions, showing their potential as all-around performers in a variety of environments.

Farmers in dry areas of sub-Saharan Africa that are characterized by pre- and post-anthesis drought stress stand to gain a great deal from these newly identified sorghum strains. Adoption of these high-yielding and drought-resistant genotypes could increase food production and strengthen farmers’ resilience against the effects of climate change.

The findings of these super sorghum genotypes offer farmers facing the challenges of climate change a glimmer of hope. By adopting these new drought-resistant strains, African farmers can improve their food security and strengthen their communities, paving the way for a more resilient and sustainable future.

In Ethiopia, regional and local representatives endorse national framework on climate services

In Ethiopia, regional government representatives endorsed in October 2023 the National Framework on Climate Services (NFCS), a tool designed to guide the establishment and delivery of climate services in key sectors: water and energy, agriculture, health, disaster risk management, and environmental protection.

This endorsement by regional state representatives marks an important step towards the implementation at regional and zonal levels of the NFCS, which was adopted at the national level in 2020.

The adoption of the Framework concluded a two-day workshop organized by the Ethiopian Meteorological Institute in partnership with CIMMYT through the AICCRA project, which aims to scale climate-smart agriculture and climate information services for the benefit of millions of small-scale farmers in Ethiopia. The workshop was also attended by ministers, state ministers and heads of federal offices from the sectors affected by climate change.

Responding and adapting to climate change requires that all affected sectors cooperate and collaborate, stressed Fetene Teshome, General Manager of the Ethiopian Meteorological Institute, in his opening remarks. Experts and regional and local representatives should come together to establish a system that can gather quality information and disseminate it to its users, he added.

“We can’t tackle climate change easily, so we have to find ways to live with it and use it to our benefit,” said Habtamu Itefa, minister of water and energy. He urged the workshop participants to approach the NFCS as a system designed to outlive governments and called them to play an essential role in its implementation in their respective regions, zones, districts and kebeles (sub-districts).

“Climate services will bring meaningful changes in agriculture”

Among the sectors most affected by climate change, agriculture accounts for about 40% of the GDP and employs more than 80% of the population, making it the backbone of the Ethiopian economy. It is thus crucial to address climate change impacts on the sector.

CIMMYT Senior Scientist, Kindie Tesfaye, explained how the AICCRA project works to enhance access to climate information services and validated climate-smart agriculture technologies in six African countries, including Ethiopia. As a stakeholder of the project, CIMMYT is training farmers, development agents, and local agricultural experts, and other agricultural value chain actors on the use of climate advisory services in collaboration with LERSHA, a digital platform providing farmers with contextualized weather forecast, inputs, mechanization and financial advisory services.

“We consider climate as a major problem for the country’s agricultural activities because the sector is heavily dependent on rain-fed production system and we believe that implementing this national framework on climate services will bring meaningful changes to the sector enabling it to manage climate risks successfully,” said Kindie Tesfaye.

The AICCRA project supported strengthening the function of the NFCS coordination team for multi- stakeholder engagement, supporting the endorsement of the framework and providing training on resource mobilization for its implementation. The project is also building capacity at different levels, promoting climate smart agriculture.

Productive in-depth discussions

Prior to the NFCS endorsement, participants shared inputs from their respective regions and sectors, providing inputs to the framework. Delegates mostly discussed capacity building needs, information delivery channels, synergetic cooperation among government institutions and mobilization of resources for implementation.

On the second day of the workshop, four different papers were presented on a seasonal climate update for the 2023 Bega season (October to December), on the impacts outlook for the upcoming Bega season, on the national state of the climate, and on climate risk management in agriculture extension.

The plenary discussion that followed was led by Fetene Teshome and offered an opportunity to the participants to raise their concerns on the implementation of the framework in their respective regional states. Many of the participants reflected on how the framework can accommodate the different ecology of various areas and how it can upgrade or replace dysfunctional meteorology infrastructures.

The Climate Risk Curriculum module that was prepared by AICCRA for agricultural extension workers was also launched during the workshop.

 

Breaking barriers in agriculture

In Nepal, the International Water Management Institute and CIMMYT conducted research on Sustainable Intensification of Mixed Farming System (SI-MFS) in collaboration with local governments in Gurbakot Municipality of Surkhet and Haleshi Tuwachung Municipality of Khotang.

The research found a noticeable shift in farmers’ interest in farming practices, where successful implementation of innovation and scaling, it’s crucial to have farmers’ interest and ownership in interventions.

Breaking barriers in agriculture

Nepal’s traditional farming system faces labor shortages, and climate-induced risks to crop production, infrastructure, investment, and agro-advisory tools. This calls for urgently redesigning agriculture practices and addressing the challenges and a noticeable shift in farmers’ interests in farming practices.

The world’s future wheat will need to withstand the climate crisis

As hotter temperatures and drought become the norm in places used to growing wheat, yields will be reduced, climate change will have some effect on most of the world’s wheat. CIMMYT is working to strengthen seed systems as demand for staple crops like wheat is only expected to increase as the climate crisis makes the world’s food system more vulnerable.
