Fertilizers redux
Long-time readers may well remember that we have talked about Malawi’s fertilizer subsidy programme a number of times here over the past — what is it now? — 15 years?
Let’s recap.
Controversially, against the advice of its most powerful donors, Malawi’s President Bingu wa Mutharika subsidized inputs through a government-funded voucher scheme known as the Farm Input Subsidy Program (FISP). Millions of small-holder farmers received fertilizer and improved seed at a fraction of the market price… With good rains and a strong response to subsidized fertilizer and improved seeds, national maize production doubled in 2006.
That’s from a recent commentary by Glenn Denning, Professor of Professional Practice at the School of International and Public Affairs, Columbia University. There has been much criticism of the strategy over the intervening years, just look at some of the articles and papers we have linked to over the years, but Prof. Denning seems to have no doubt that in the end it worked, and not just in Malawi.
Critics argued Mutharika struck it lucky with the weather, and that these results could not be sustained… However, despite changes in national leadership and stop-start support from Malawi’s donors, the FISP has continued as a strategy for increasing farm productivity and national food security. The results are impressive. Since 2005, Malawi’s farmers have generated surpluses over national requirements in all but three years—2015, 2016, and 2018… National maize production increased by 79 percent between 2004 and 2019 (comparing averages for 2002-2004 and 2017-2019). This increase was the product of a 62% increase in average yield and 10% increase in harvested area. As a country with limited land resources and a high population density, Malawi’s increase in maize production mirrored the experience of Asia, demonstrating that it was possible to intensify existing cultivated land under rainfed conditions.
So, mission accomplished, right? Ahem, not quite…
Despite these encouraging results from Malawi and sub-Saharan Africa as a whole, it would be premature to declare “mission accomplished.”
Damn. So what else do we need to do, for pity’s sake? I was thinking we had the elusive silver bullet here.
Well, Prof. Glenn Denning does double down on better-maize-seeds-plus-fertilizer, but says it’s time to add a distinctly green twist:
- reduce the footprint of fertilizers through more precise recommendations and deploying more efficient varieties
- restore abandoned land through the strategic use of legumes and trees
- abandon some annual crops for more tree-based systems
- reduce post-harvest losses
- protect natural ecosystems
Fertilizers, plus agrobiodiversity, you could say.
Brainfood: Diversification, Nepal agrobiodiversity, Agroecology double, Agroforestry, Seeds of deforestation, Millets models
- Environmental context and herbivore traits mediate the strength of associational effects in a meta-analysis of crop diversity. More crops in fields means fewer pests, by and large.
- Approaches and Advantages of Increased Crop Genetic Diversity in the Fields. How they get more crops into fields in Nepal, and why it’s a good thing to do so.
- Agroecology as a transformative approach to tackle climatic, food, and ecosystemic crises. More crops in fields can be transformative.
- Agroecology Can Promote Climate Change Adaptation Outcomes Without Compromising Yield In Smallholder Systems. More crops (and other things, to be fair) in fields means better climate change adaptation.
- Providing targeted incentives for trees on farms: A transdisciplinary research methodology applied in Uganda and Peru. To get more tree crops in fields, follow the money.
- Impact of small farmers’ access to improved seeds and deforestation in DR Congo. Getting more, better crops into fields may lead to loss of primary forest if they don’t come with fertilizers.
- Small-scale farming in drylands: New models for resilient practices of millet and sorghum cultivation. Models show that plant growing cycle, soil water-holding capacity and soil nutrient availability determine how much sorghum and millets are in fields.

- Jeremy continues to dig deep into biofortification, and is not happy with what he finds out about iron-rich beans.
- Maybe he’ll donate to one of CIFOR-ICRAF’s nutrition-flavoured tree projects instead.
- Don’t worry, maybe lablab can be biofortified now that we have its genome.
- Speaking of trees, if you want to plant one in a particular botanic garden or arboretum, is it likely to thrive, now and in the future? Find out using the BGCI Climate Assessment Tool.
- Speaking of botanic gardens and arboreta, here are some resources on how they manage their tree collections.
- Prof. Alberto Grandi debunks the many myths of Italian cuisine.
- Christine Gatwiri doesn’t think maize can be replaced in Kenyan cuisine. I just hope it can be replaced in Italian cuisine.
- Will gene-edited teff finds its way into Ethiopian cuisine? And would it be a bad thing if it did? It depends on being open about it I guess…
- … so let’s remind ourselves of some ways plant breeding can usefully engage with the public, shall we?
- And let’s also remind ourselves that plant breeding is necessary, for example to protect our food supply against diseases. The Guardian has receipts.
- Prof. Glenn Denning doubles down on the whole better-maize-seeds-plus-fertilizer thing in Africa, but adds some greenery. In more senses than one. So yes, trees are allowed. And maybe even lablab and teff for all I know. Incidentally, the above gene-edited teff is shorter than “normal”, which could mean it might respond to more fertilizer in the same way as those Green Revolution wheats and rices once did.
- Ah yes, the “transformation” and “revolution” tropes are definitely all over the discourse on African agriculture these days. According to this article, what transformation and revolution will require are consistent planning, political backing, a fit-for-purpose lead organization and that perennial favourite, result-oriented implementation. No word here on greenery specifically, but at least it’s not ruled out.
- And to back all that up, CGIAR gets The Economist Impact to say that more funding is needed for agricultural research and innovation. Results-oriented, naturally.
- Meanwhile, in Suriname, Bangladesh and Guinea-Bissau, local people are saving their traditional seeds and agricultural practices. The revolution will eat its own (seeds).
- Phew, the Ukrainian seed collection is squared away. Now for Suriname, Bangladesh, Guinea-Bissau…
