What happens when farming families in poor countries lose their most important possessions?

Through the words of one African family, we learn in this short (4 minutes, 50 seconds) film, 'Why livestock?' from the International Livestock Research Institute (ILRI) how livestock losses change lives.

By providing nourishing food, regular income, traction for ploughing, and manure to fertilize their croplands, farm animals are the foundation of some one billion lives and livelihoods.

‘Life is hard for us now without livestock,’ says this family.

Can we grow more food and feed more people and capture more carbon? 'Yes,' say those organizing an Agriculture and Rural Development Day held on 4 December 2010 in parallel with the Sixteenth Conference of the Parties (COP16) to the United Nations Framework Convention on Climate Change taking place at Cancún, Mexico.

Yes—if we support the small-scale producers and sellers of food and acknowledge that climate security and food security depend on each other. Read a report of the Agriculture and Rural Development Day at the 'CGIAR in Action' blog: Opening the door for agriculture at COP16,' 7 December 2010.

'Yes,' agrees Alex Perry, a journalist writing for Time Magazine this week (13 December 2010).

Yes—if we make green development work for the 7 out of 10 Africans living on small farms. 'Climate change is the mother of all negative externalities,' says Perry, who defines an 'externality' as a by-product of economic activity not included on the balance sheet.

'The problem is measuring it: How do you calculate the cost of climate change and then apportion it fairly among the world's businesses? Skeptics say rich governments and Big Industry can't or won't. Some, like Nicholas Stern, who produced the British government's Review of the Economics of Climate Change, say it can be done. But Stern's figures—which show that climate change could cut global gross domestic product by 20% if quick action is not taken—have been criticized as both over- and underestimates. And others argue that since climate change most affects the poor, programs to lift the developing world are the best way to fight its impact.

'But what if the externality could be accounted for, in a way that helped the poor? What if the economic rule book could be rewritten so that fighting climate change became development? . . . As a result of works by Sukhdev and others, UNEP [United Nations Environment Programme] executive director Achim Steiner can measure the financial benefits of saving the planet. New assessments indicate that "nature may represent between 50% and 90% of incomes in the developing world," he says. "In the past, these services have been invisible or near invisible in national and international accounts. This should and must change.". . .

'What is clear is the potential. "It is essential that climate change be viewed as a major development opportunity for Africa," World Bank managing director Ngozi Okonjo-Iweala said last year.

'And this is primarily a developing-world opportunity for two reasons. First, the poor world tends to be rich in things like forest and sunshine. Second, the rich world has few incentives to change its ways. "Suddenly there is the possibility of a whole new green trajectory for Africa," says UNEP spokesman Nick Nuttall. "You might ask, Can combatting climate change actually offer a new future for Africa?" . . .

'The question of whether green development becomes an African norm hinges on whether it works for companies and business leaders. That means Africa's farmers: 7 out of 10 Africans live on small farms. Unexpectedly, scientists are finding that it is those farmers who offer some of the best reasons for hope.'

New book on livestock in developing countries

Siboniso Moyo, ILRI’s representative for southern Africa, holds a copy of ‘The role of livestock in developing communities: Enhancing multifunctionality’ which was recently launched in South Africa (photo credit: ILRI).

A new book co-published by the University of the Free State South Africa, the Technical Centre for Agricultural and Rural Cooperation (CTA) and the International Livestock Research Institute (ILRI) calls for more investment in livestock production to fight poverty and promote human health in developing countries.

The role of livestock in developing communities: Enhancing multifunctionality was launched on 9 November 2010 at the University of the Free State, in Bloemfontein, South Africa.

Farm animals continue to play several central roles in the livelihoods of the people in developing countries, ranging from providing households with high-quality foods, good nutrition and regular incomes to providing labourers with jobs, community members with social status and farmers and herders with ways to sustain food production.

This book highlights the livestock sector’s contribution to the social and economic progress of developing communities and advocates public- and private-sector investments in livestock production.

The publication is a product of a satellite symposium that was part of the 10th World Conference on Animal Production, held in Cape Town in November 2008. The symposium, jointly organized by ILRI and the University of the Free State, focused on livestock livelihood strategies for meeting the United Nations Millennium Development Goals.

‘We were pleased with the chance to work together with the University of the Free State in a side event during the World Conference of Animal Production 2008, which led to the production of this book,’ said Siboniso Moyo, ILRI’s representative for southern Africa, during the launch.

Moyo, along with Frans Swanepoel, senior director of research and professor of sustainable agriculture at the University of the Free State, Bloemfontein, South Africa, and Aldo Stroebel, director of international affairs and associate professor at the Center for Sustainable Agriculture and Rural Development at the same university, provided editorial oversight for the book.

John McDermott, ILRI’s deputy director general for research; Canagasaby Devendra, a tropical animal production specialist who formerly worked at ILRI, and Akke van der Zijpp, another former ILRI staff member who is now professor in livestock production systems at the Wageningen University and Research Centre, in the Netherlands, served in the editorial advisory committee that steered production of the book.

‘The “multifunctionality” of livestock is an important concept to understand when working with developing communities,’ said Moyo. ‘Viewing research and development challenges through a livestock lens,’ she said, ‘can help us make even greater use of the many functions livestock serve in poor communities and so as to increase their contribution to livelihoods.’

The book launch was attended by Monty Jones, executive director of the Forum for Agricultural Research in Africa, chairperson of the Global Forum of Agricultural Research and a World Food Prize Laureate (2004), who contributed the foreword to the book, and Norman Casey, president of the 10thWorld Conference of Animal Production 2008.

The book describes successful livestock development strategies, including ways to promote gender equality and to empower women through livestock development and ways to develop small-scale livestock enterprises without harming the environment.

Targeting academic professionals, industry experts, government officials and academics interested in increasing the contributions livestock enterprises can make to human well-being and developing-country economies, the new publication includes case studies and frameworks, discussions of key global policy development issues, and the main challenges and constraints of smallholder livestock production systems around the world.

The book is available in South Africa through Sun Media Bloemfontein and can be ordered through their e-shop: http://www.sun-e-shop.co.za/?Task=moreinfo&SKU=ISBN+978-0-86886-798-4

A new publication, Agriculture-Climate Letters, published by the Climate Change, Agriculture and Food Security program, this week highlight a paper published on the impacts of a 4ºC warmer world on African agriculture and food security. The lead author of the paper is Philip Thornton, an agricultural systems analyst with the International Livestock Research Institute (ILRI).

‘. . . The UK Met Office says a 4 degree [warmer] world is quite possible, and will plausibly be reached by 2070 or even 2060–in our children’s lifetimes. This will mean average temperature rises of a massive 15ºC in the Arctic, and 3-8ºC in the world’s most populated areas.

‘. . . Agriculture is highly sensitive even to a 2 degree scenario; a 4 degree world is beyond the bounds of both local and global knowledge, both modern and historical experience. . . .

‘A new paper, Agriculture and food systems in sub-Saharan Africa in a four-plus degree world, by Philip Thornton, Peter Jones, Polly Ericksen and Andrew Challinor, foresees profound effects. . . . [E]nsembles of models suggest average yield drops of 19% for maize and 47% for beans, and much more frequent crop failures. . . . Africa-wide, a massive 1.2 million km2 may be forced to flip from typical mixed farms, with both crops and livestock, into pure rangeland. . . .

‘Thus a 4 degree world calls for adaptive capacity in agriculture that is not just about increasing the resilience of current systems, but about completely new ways of farming and consuming. . . . Thornton and colleagues highlight four areas for immediate policy attention:

  • supporting farmers’ own risk-management strategies
  • strengthening basic data collection in agriculture
  • investing seriously in genebanks
  • improving governance of food systems so that poor people can get affordable food

‘. . . Rapidly urbanising populations will need to eat nationally and regionally grown food. If +4 degrees signals the end to half a millennium of Africans eating maize, will the 21st century usher in a new era of indigenous urban foods, be they free-range hamburgers or drought-resistant yamburgers?

The New Harvest: Agricultural Innovation in Africa_By Calestous Juma

Madeleine Bunting discusses in the Guardian's Poverty Matters Blog today (3 December 2010) a new report by Harvard academic Calestous Juma, The New Harvest: Agricultural Innovation in Africa.

Bunting says: 'Rising food prices and terrible future scenarios of the impact of climate change on food production, are focusing minds on what is perceived as Africa's huge untapped potential for agriculture. This week yet another report from the International Food Policy Research Institute warns that climate change could push prices up by 130%, and calls for unprecedented human ingenuity to meet the challenge of feeding a burgeoning population. . . . Central to all the discussion is the assertion that Africa could produce far more food than it currently does. . . . On one side there is a powerful lobby which argues that biotechnology, massive investment in irrigation and mechanisation are the way forward, and on the other side are those who argue that these kinds of investments are usually tied up in big corporate deals in which local smallholder subsistence farmers lose out. . . . Juma and his prestigious panel of international experts have attempted to pick a politically feasible path between these two positions. . . . [W]hat will delight these very critics is Juma's championing of the smallholder farmer–not as an encumbrance to development but as central to its achievement. . . . China offers a fascinating model for Africa that is radically different from the western model of high-investment, export-orientated agriculture–the carnations from Kenya model. The key to China's success, argues Juma, is "a strong, competent, developmental state". . . .'

SciDev.Net reports today that experts in African food security gave Juma's report a cautious welcome.

'Bruce Campbell, head of the Consultative Group on International Agricultural Research's (CGIAR) programme on climate change, agriculture and food security, said: "While Juma's book is optimistic, one needs to recognise that there are tremendous challenges that are not very simple to solve". . . .

'And Philip Thornton, a senior scientist at International Livestock Research Institute in Kenya, who led a recent study that concluded global warming could spell a catastrophe for Africa's agriculture, warned that "there are many [climate change] factors that are not under Africa's control".

'These will work in the opposite direction to improvements in yields and new crop varieties, he said. "I was a little surprised when reading the press release about the report as it doesn't make much mention of climate change."'

Lindiwe Majele Sibanda, CEO of the Food, Agriculture and Natural Resources Policy Analysis Network, based in South Africa, and a member of ILRI's board of trustees, is a contributing author and member of the report's international advisory panel.

Bottom line implication: A 4-degree warmer world calls for adaptive capacity in agriculture that is not just about increasing the resilience of current systems but about completely new ways of farming and consuming.

The Guardian this week quotes agricultural systems analyst Philip Thornton, of the International Livestock Research Institute (ILRI), on the severe impacts that a 4ºC rise in temperature, now expected to occur within this century, will have on African livelihoods and food production.

'A hellish vision of a world warmed by 4ºC within a lifetime has been set out by an international team of scientists, who say the agonisingly slow progress of the global climate change talks that restart in Mexico today makes the so-called safe limit of 2ºC impossible to keep. A 4ºC rise in the planet's temperature would see severe droughts across the world and millions of migrants seeking refuge as their food supplies collapse.

'"There is now little to no chance of maintaining the rise in global surface temperature at below 2ºC, despite repeated high-level statements to the contrary," said Kevin Anderson, from the University of Manchester, who with colleague Alice Bows contributed research to a special collection of Royal Society journal papers published tomorrow. "Moreover, the impacts associated with 2ºC have been revised upwards so that 2ºC now represents the threshold [of] extremely dangerous climate change.". . .

'Rachel Warren, at the University of East Anglia, described a 4ºC world in her research paper: "Drought and desertification would be widespread. . . . There would be a need to shift agricultural cropping to new areas, impinging on [wild] ecosystems. Large-scale adaptation to sea-level rise would be necessary. Human and natural systems would be subject to increasing levels of agricultural pests and diseases, and increases in the frequency and intensity of extreme weather events."

'Warren added: "This world would also rapidly be losing its ecosystem services, owing to large losses in biodiversity, forests, coastal wetlands, mangroves and saltmarshes [and] an acidified and potentially dysfunctional marine ecosystem. In such a 4ºC world, the limits for human adaptation are likely to be exceeded in many parts of the world.". . .

'In sub-Saharan Africa, "the prognosis for agriculture and food security in a 4ºC world is bleak", according Philip Thornton, of Kenya's International Livestock Research Institute, who led another research team. He notes there will be an extra billion people populating the continent by 2050.

'"Croppers and livestock keepers in sub-Saharan Africa have in the past shown themselves to be highly adaptable to short- and long-term variations in climate. But the kind of changes that would occur in a 4ºC+ world would be way beyond anything experienced in recent times. It is not difficult to envisage a situation where the adaptive capacity and resilience of hundreds of millions of people could simply be overwhelmed by events," Thornton's team concludes. . . .'

A 4-degree C warmer world

Projections of global warming relative to pre-industrial for the A1FI emissions scenario—the one we’re currently on. Dark shading shows the mean ±1 standard deviation for the tunings to 19 AR4 GCMs [IPCC Fourth Assessment General Circulation Models]  and the light shading shows the change in the uncertainty range when . . . climate-carbon-cycle feedbacks . . . are included. Published in a Royal Society special issue on climate change, 29 November 2010 (graphic credit: Philosophical Transactions of the Royal Society Series A, Special Issue, 29 November 2010).

An article in the highly regarded Climate Progress website says names a paper by agricultural systems analyst Philip Thornton, of the International Livestock Research Institute (ILRI), titled 'Agriculture and food systems in sub-Saharan Africa [SSA] in a 4°C+ world', as one of the more important articles appearing in a current special issue on climate change of the Philosophical Transactions of the Royal Society Series A.

'"In . . .  a 4°C [warmer] world, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would largely be exceeded throughout the world."

'One of the greatest failings of the climate science community (and the media) is not spelling out as clearly as possible the risks we face on our current emissions path, as well as the plausible worst-case scenario, which includes massive ecosystem collapse. So much of what the public and policymakers think is coming is a combination of:

  • The low end of the expected range of warming and impacts based on aggressive policies to reduce emissions (and no serious carbon-cycle feedbacks)
  • Analyses of a few selected impacts, but not an integrated examination of multiple impacts
  • Disinformation pushed by the anti-science, pro-pollution crowd

'In fairness, a key reason the scientific community hasn’t studied the high emissions scenarios much until recently because they never thought humanity would be so self-destructive as to ignore their warnings for so long, which has put us on the highest emissions path (see U.S. media largely ignores latest warning from climate scientists: “Recent observations confirm … the worst-case IPCC scenario trajectories (or even worse) are being realised”—1000 ppm [A1FI]).

'A special issue of the Philosophical Transactions of the Royal Society A, “Four degrees and beyond: the potential for a global temperature increase of four degrees and its implications,” lays out this 4°C (7°F) world. Warming of 7ºF is certainly not the worst-case in the scientific literature (see M.I.T. doubles its 2095 warming projection to 10°F—with 866 ppm and Arctic warming of 20°F and “Our hellish future: Definitive NOAA-led report on U.S. climate impacts warns of scorching 9 to 11°F warming over most of inland U.S. by 2090 with Kansas above 90°F some 120 days a year — and that isn’t the worst case, it’s business as usual!”).

'But for the first time, “A hellish vision of a world warmed by 4ºC within a lifetime has been set out by an international team of scientists,” as the UK’s Guardian describes it:

'A 4ºC rise in the planet’s temperature would see severe droughts across the world and millions of migrants seeking refuge as their food supplies collapse.

'These papers began as conference presentations . . . . In a must-read paper that is the source of the top figure, “When could global warming reach 4°C?” Betts et al. drop this bombshell:

'"Using these GCM projections along with simple climate-model projections, including uncertainties in carbon-cycle feedbacks, and also comparing against other model projections from the IPCC, our best estimate is that the A1FI emissions scenario would lead to a warming of 4°C relative to pre-industrial during the 2070s. If carbon-cycle feedbacks are stronger, which appears less likely but still credible, then 4°C warming could be reached by the early 2060s in projections that are consistent with the IPCC’s ‘likely range’.". . .

'Another important Royal Society article is the concluding piece, “The role of interactions in a world implementing adaptation and mitigation solutions to climate change,” by Rachel Warren.  She makes a crucial point that is all too neglected in most discussions of adaptation — it is the interaction of impacts that is likely to overwhelm, particularly when you consider the very real risk of eco-system collapse over large parts of the Earth:

'"… a 4°C world would be facing enormous adaptation challenges in the agricultural sector, with large areas of cropland becoming unsuitable for cultivation, and declining agricultural yields. This world would also rapidly be losing its ecosystem services, owing to large losses in biodiversity, forests, coastal wetlands, mangroves and saltmarshes, and terrestrial carbon stores, supported by an acidified and potentially dysfunctional marine ecosystem. Drought and desertification would be widespread, with large numbers of people experiencing increased water stress, and others experiencing changes in seasonality of water supply. There would be a need to shift agricultural cropping to new areas, impinging on unmanaged ecosystems and decreasing their resilience; and large-scale adaptation to sea-level rise would be necessary. Human and natural systems would be subject to increasing levels of agricultural pests and diseases, and increases in the frequency and intensity of extreme weather events.

'"In such a 4°C world, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would largely be exceeded throughout the world. Hence, the ecosystem services upon which human livelihoods depend would not be preserved. Even though some studies have suggested that adaptation in some areas might still be feasible for human systems, such assessments have generally not taken into account lost ecosystem services. . . .

'. . . [T]here are several important articles, like “Agriculture and food systems in sub-Saharan Africa [SSA] in a 4°C+ world,” which concludes:

'The prognosis for agriculture and food security in SSA in a 4°C+ world is bleak. Already today, the number of people at risk from hunger has never been higher: it increased from 300 million in 1990 to 700 million in 2007, and it is estimated that it may exceed 1 billion in 2010. The cost of achieving the food security Millennium Development Goal in a +2°C world is around $40–60 billion per year, and without this investment, serious damage from climate change will not be avoided. Currently, the prospects for such levels of sustained investment are not that bright. Croppers and livestock keepers in SSA have in the past shown themselves to be highly adaptable to short- and long-term variations in climate, but the kind of changes that would occur in a 4°C+ world would be way beyond anything experienced in recent times. There are many options that could be effective in helping farmers adapt even to medium levels of warming, given substantial investments in technologies, institution building and infrastructural development, for example, but it is not difficult to envisage a situation where the adaptive capacity and resilience of hundreds of millions of people in SSA could simply be overwhelmed by events. . . .

Maize farming in Mozambique

As climate change negotiations begin this week in Mexico, a new study published in the journal Philosophical Transactions of the Royal Society Series A, examining the potential impact of a four-degree temperature increase on food production in sub-Saharan Africa, reports that growing seasons of much of the region’s cropped areas and rangelands will be reduced in length by the 2090s, seriously damaging the ability of these lands to grow food.

Painting a bleak picture of Africa’s food production in a 'four-plus degree world,' the study sends a strong message to climate negotiators at a time when they are trying to reach international consensus on measures needed to keep average global temperatures from rising by more than two degrees Centigrade in this century. The study calls for concerted efforts to help farmers cope with potentially unmanageable impacts of climate change.

In most of southern Africa, growing seasons could be shortened by about 20 per cent, according to the results of simulations carried out using various climate models. Growing seasons may actually expand modestly in eastern Africa. But despite this, for sub-Saharan Africa as a whole, a temperature increase of five degrees by the 2090s is expected to depress maize production by 24 per cent and bean production by over 70 per cent.

'Africa’s rural people have shown a remarkable capacity to adapt to climate variability over the centuries,' said lead author Philip Thornton, with the Kenya-based International Livestock Research Institute (ILRI), which forms part of the Consultative Group on International Agricultural Research (CGIAR). 'But temperature increases of four degrees or more could create unprecedented conditions in dozens of African countries, pushing farmers beyond the limits of their knowledge and experience.' 

It seems unlikely that international climate policies will succeed in confining global warming to a two-degree increase, and even this will require unprecedented political will and collective action, according to the study.

Many options are already available that could help farmers adapt even to medium levels of warming, assuming substantial investment in new technology, institution building, and infrastructure development, for example. But it is quite possible that the adaptive capacity and resilience of hundreds of millions of people in Africa could simply be overwhelmed by events, say the authors.

The rate of cropping season failure will increase in all parts of the region except Central Africa, according to study results. Over a substantial part of eastern Africa, crops already fail in one out of every four years. By the 2090s, higher temperatures will greatly expand the area where crops fail with this frequency. And much of southern Africa’s rainfed agriculture could fail every other season.

'More frequent crop failures could unleash waves of climate migrants in a massive redistribution of hungry people,' said Thornton. 'Without radical shifts in crop and livestock management and agricultural policies, farming in Africa could exceed key physical and socio-economic thresholds where the measures available cease to be adequate for achieving food security or can’t be implemented because of policy failures.'

'This is a grim prospect for a region where agriculture is still a mainstay of the economy, occupying 60 per cent of the work force,' said Carlos Seré, Director General of ILRI. 'Achieving food security and reducing poverty in Africa will require unprecedented efforts, building on 40 years of modest but important successes in improving crop and livestock production.'

To help guide such efforts, the new study takes a hard look at the potential of Africa’s agriculture for adapting successfully to high temperatures in the coming decades; the study also looks at the constraints to doing so.

Buffering the impacts of high temperatures on livestock production will require stronger support for traditional strategies, such as changing species or breeds of animals kept, as well as for novel approaches such as insurance schemes whose payouts are triggered by events like erratic rainfall or high animal death rates, according to the study.

However, Thornton says that uncertainty about the specific impacts of climate change at the local level, and Africa’s weak, poorly resourced rural institutions, hurt African farmers' ability to adopt such practices fast enough to lessen production losses. Moreover, governments may not respond to the policy challenges appropriately, as demonstrated by the 2008 food crisis, when many countries adopted measures like export bans and import tariffs, which actually worsened the plight of poor consumers.

The study recommends four actions to take now to reduce the ways climate change could harm African food security.

1.     In areas where adverse climate change impacts are inevitable, identify appropriate adaptation measures and pro-actively help communities to implement them.

2.     Go 'back to basics' in collecting data and information. Land-based observation and data-collection systems in Africa have been in decline for decades. Yet information on weather, land use, markets, and crop and livestock distributions is critical for responding effectively to climate change. Africa’s data-collection systems could be improved with relatively modest additional effort.

3.     Ramp up efforts to maintain and use global stocks of crop and livestock genetic resources to help Africa’s crop and livestock producers adapt to climate change as well as to the shifts in disease prevalence and severity that such change may bring.

4.     Build on lessons learned in the global food price crisis of 2007–2008 to help address the social, economic and political factors behind food insecurity.

The CGIAR and the Earth System Science Partnership recently embarked on the most comprehensive program developed so far to address both the new threats and new opportunities that global warming is likely to cause agriculture in the world’s developing countries. The Climate Change, Agriculture and Food Security program assembles relevant experts to work with decision makers at all levels—from government ministries to farmers’ fields—to translate knowledge into effective action.

The ILRI study underlines the urgency and importance of that research. It will inform the discussions of some 500 policy makers, farmers, scientists and development experts expected to attend an ‘Agriculture and Rural Development Day’, on 4 December, which will be held alongside a two-week United Nations Conference on Climate Change taking place in Cancún, Mexico. Participants at the one-day event will identify agricultural development options for coping with climate change and work to move this key sector to the forefront of the international climate debate.

'A four-plus degree world will be one of rapidly diminishing options for farmers and other rural people,' said Seré. 'We need to know where the points of no return lie and what measures will be needed to create new options for farmers, who otherwise may be driven beyond their capacity to cope.'
