Resilience Building through agroecological intensification in Zimbabwe (RAIZ)

Zimbabwe’s agricultural sector is predominantly subsistence-oriented, with maize as the main staple crop and limited use of external inputs. To promote sustainable and climate-smart agriculture, Zimbabwe has developed a 10-year framework (2018-2028) that emphasizes the adoption of climate-smart agriculture (CSA). However, the adoption of CSA practices remains limited in the country. Agroecological practices (AE) and the systemic perspective embedded in agroecological approaches hold great potential to address climate change and enhance agricultural sustainable intensification in Zimbabwe. RAIZ was conceived as the research component of the “Team Europe Initiative” (TEI) on “Climate-Smart Agriculture for Resilience Building”, formulated by the European Union (EU) delegation in Zimbabwe together with its member states.

Led by the French Agricultural Research Centre for International Development (CIRAD), in partnership with CIMMYT and the University of Zimbabwe, with funding from the European Union, RAIZ operates along a gradient of declining rainfall from Murewa in Natural Region II to Mutoko in Natural Region IV. Both districts are in the Mashonaland East province. Under RAIZ, CIMMYT leads Work Package 3 which involves ‘developing the capacity of extension and advisory services on agroecological approaches’ is actively involved in research and development activities, including the creation of training materials and the establishment of on-farm trials. In efforts to address challenges associated with low soil fertility on Zimbabwe’s granitic sandy soils. CIMMYT scientists working on RAIZ are testing the contribution of organic fertilizers and conservation agriculture in building up soil organic carbon and bringing back soil life to these mostly dead soils. These efforts aim to support farmers in adopting sustainable and climate-smart agricultural practices, ultimately contributing to the long-term resilience and prosperity of Zimbabwe’s agricultural sector.

Key objectives 

The overall objective is to support government in the development and implementation of scientifically tested agroecological approaches which will enhance agricultural production and resilience to climate change in Zimbabwe.

In addition, the project focuses on protecting the environment and reducing greenhouse gas (GHG) emissions. It will provide scientific evidence and experience for the design of climate-smart agriculture (CSA) at the plot, farm, and landscape levels, contextualized for mixed crop–livestock farms under sub-humid to semi-arid environments.

Boosting groundnut value chains

Representatives from various sectors in Tanzania met to discuss the challenges and opportunities in the country’s groundnut value chain, with the aim of establishing a platform for dialogue among stakeholders involved in groundnut production and distribution.

The meeting was organized by TEMNAR Co. Ltd., and brought together key stakeholders including farmers, government officials, research institutes, NGOs, and partners such as Ruvuma Commercialization and Diversification of Agriculture (RUCODIA), SWISSAID, and Vodacom. All participants affirmed the meeting’s overall impact and significance, acknowledging that the event would help lay a strong foundation for the growth of groundnut farming, particularly in Mtwara and Lindi regions.

The meeting featured presentations from scientists at the Tanzania Agricultural Research Institute (TARI) — who addressed topics such as groundnut agronomy and seed technology — and representatives from TEMNAR, who outlined strategies to facilitate effective collaboration among stakeholders and achieve mutually beneficial outcomes. Discussions centered on topics such as groundnut varieties, market demands, and the importance of quality and cleanliness throughout the production process. Trust in business relationships was identified as a key factor for success.

Participants at the meeting shared innovative ideas and identified opportunities for strengthening the sector. They highlighted, for example, the need for aggregators to specify their groundnut volume requirements and the application of simple technologies — such as hand push planters and threshing machines — to increase production efficiency. They also emphasized the importance of planting new TARI-bred groundnut varieties to meet market demand, and the establishment of additional seed multiplication farms to increase seed availability.

Another key component of the meeting was assessing the challenges faced by local groundnut farmers. These include the shortage of good groundnut seed, limited agronomical knowledge, and the labor-intensive nature of planting, harvesting, and picking the crop. To address these challenges, participants suggested making agricultural inputs and tools more accessible to farmers, conducting technology demonstrations, and establishing seed multiplication farms across different districts.

Both farmers and aggregators expressed their commitment to making changes in their farming practices; aggregators are now able to access groundnuts easily through phone calls, while farmers enjoy improved access to markets and better prices. A number of follow-up actions have also been planned as a result of the meeting, such as product buyback initiatives during the harvest season and the establishment of field days to help reach more farmers and aggregators at the local level.

Chewing over the future of global food security

CIMMYT Director General, Bram Govaerts, praised China’s recent efforts to curb its reliance on food imports and increase funding for technology-driven breeding techniques, including gene editing. Govaerts suggested such measures have managed to shield China from the unfolding global food crisis that is caused by a mix of factors such as regional conflicts, climate change and rising protectionism.

Fall armyworm research, development and extension for horticulture

Breeding for fall armyworm resistance in maize: an update from CIMMYT

Staff from the Queensland Department of Agriculture and Fisheries (DAF), Agriculture Victoria, Food and Fibre Gippsland, and Bowen Gumlu Growers Association joined B.M. Prasanna (Maize Program Director at CIMMYT & CGIAR Plant Health Initiative Lead) on 19th October 2023 to learn about CIMMYT’s efforts and experiences with fall armyworm management at the global scale, and to build partnerships between CIMMYT and Australian institutions for future collaboration on plant health management.

At the online meeting, Prasanna shared CIMMYT’s research and development on FAW management in maize, including breeding for insect-pest resistance, screening maize germplasm against FAW under artificial infestation, and collaborative approaches on integrated pest management of FAW.

Key points from the discussion:

  • Collaborative efforts are important in managing FAW, and international R&D collaboration is as important as country-level research efforts.
  • CIMMYT has made significant progress in breeding FAW-tolerant maize hybrids (with native genetic resistance); three such hybrids have been released by national partners in Kenya, Zambia, Malawi, South Sudan, and Ghana, and several more countries in Africa are in the pipeline for release and deployment of these hybrids.
  • Insect resistance management is critical wherever Bt maize varieties have been already released or in the process of release.
  • Both conventionally derived and Bt-based resistant maize varieties have their own importance in FAW management.
  • Need to intensify breeding activities for developing elite maize germplasm with FAW resistance together with other important traits, and fast-track deployment of FAW-tolerant elite maize hybrids.
  • Possible to achieve synergies between host plant resistance and other IPM approaches for sustainable management of FAW.
  • Researchers interested in accessing germplasm from CIMMYT’s breeding program can source through a standard material transfer agreement.

Dr Prasanna responded to several queries from the participants of the meeting. Australian researchers and CIMMYT showed interest in further research collaboration. Dr Ramesh Raj Puri, DAF Extension Officer, facilitated the meeting.

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.

 

Global Hunger Challenges Grow

Bram Govaerts, CIMMYT director general, underscored the far-reaching implications of Russia’s invasion of Ukraine for agricultural production and international trade at the recent World Food Prize Borlaug Dialogue 2023.

Govaerts also noted that scientific and political responses tend to be reactive, as seen in the rapid development of vaccines in response to the emergence of the new virus during the COVID-19 pandemic.
