Experts launch tool for identifying major rice weeds of Africa

A new interactive tool for identifying nearly 200 different weed species of lowland rice in East and West Africa was recently unveiled at the Africa Rice Center (AfricaRice). The tool is built on a comprehensive knowledge base that can be accessed online ( and offline on laptops and CD-ROMs or as an app on smartphones and tablet computers.


Better rice for higher incomes: Enhancing rural livelihoods through improving post-harvest handling and rice quality in Ghana

This Research into Use website describes how a set of practical post-harvest technologies has helped the government of Ghana to improve the quality of locally grown rice, reducing imports by 30%. Functional links and communication channels between providers and users of improved rice post-production technologies have been initiated and promoted in West Africa. The new partners from Nigeria, Mali, Burkina Faso, Benin and Togo found the outputs relevant to their countries. Promotional strategies to introduce suitable technologies and practical solutions for the improvement of locally parboiled rice have been refined and developed, thereby aiming to increase the income of stakeholders in the production chain and improve product quality and safety.Although the use of this knowledge initially focused on the townships where it was developed, training manuals summarizing the fully tested and validated practices are now available. Agricultural extension agents are using the training manuals to transfer the knowledge to more farmers and processors. It could benefit an estimated 400,000 small-scale farmers and 125,000 women parboilers in Ghana alone.


IRRI – Our Science – Adding Value

IRRI develops ways to add economic, nutritional, and environmental value to rice by reducing postharvest losses, improving grain quality of new rice varieties, improving value-chain linkages, and investigating uses of husks and straw to produce bioenergy, cut carbon emissions, and increase carbon sequestration. Present postharvest losses in the developing world can be between 15 and 25%. In addition, poor quality can cause financial loss in the market of 10–20%. IRRI works to improve the postharvest value chain, as well as identifying and verifying the effectiveness of postharvest technologies with end-users. Each year, hundreds of millions of tons of rice straw and husks are produced and are commonly disposed of by burning, thus emitting greenhouse gases. IRRI is determining the variability and digestibility of straws as livestock feed to provide local business opportunities for extra income.In addition, IRRI is developing practical ways to generate and use biochar, which is derived from rice residues, to reduce carbon emissions and improve soil fertility. Demand for specialty rice products is increasing globally. Supplying rice varieties for these high-value markets will increase economic benefits to farmers and nutritional benefits to consumers. The site includes a Rice Breeding Course which introduces rice breeding including important scientific approaches such as breeding for tolerance to biotic and abiotic stresses. It explains participatory varietal selection and breeding, which aim to ensure maximum relevance to improving the rice value chain and adoption by farmers. It also advises on how to evaluate quality.


The Global Rice Science Partnership

The Global Rice Science Partnership (GRiSP) provides a single strategic plan and unique new partnership platform for impact-oriented rice research for development. It is designed to more effectively solve development challenges. GRiSP streamlines current rice research for development activities of the CGIAR and aligns them with more than 900 rice research and development partners worldwide to: • Increase rice productivity and value for the poor • Foster more sustainable rice-based production • Help rice farmers adapt to climate change• Improve the efficiency and equity of the rice sector


Climate Resilient Rice Commercialization Sector Development Programme

This Asian Development Bank Climate Resilient Rice Commercialization Sector Development programme is proposed to support and accelerate the efficient and effective implementation of the Strategy on Agriculture and Water (SAW) and the "Policy on the Promotion of Paddy Production and Rice Export" (the Rice Policy). It will address food security and rice commercialization by prioritizing: (i) strengthening the rice value chain; (ii) improving the legal and regulatory framework in agricultural land management; (iii) improving access to credit by paddy producers and rice millers/exporters; and (iv) enhancing paddy production and productivity through improved irrigation water use efficiency, establishment of paddy post-harvesting facilities, and paddy crop insurance pilots.
