Tastier Tomatoes?

tama

This is a quick post. I just saw this piece on hydroponic tomatoes   that are reported to be as flavorful as heirloom varieties. What is the environmental impact of large scale greenhouses used for growing crops that would otherwise not be grown in that area, one wonders?  Time to plug in my favorite food rule: Eat in Season. In summer, enjoy the tomatoes, can them if you like for winter but when the snow comes in do think about all the root vegetables you could savor. The comments are also worth a read and it took only a quick glance to note that, yes, Monsanto had been mentioned, never mind that it has nothing to do with the story!

Climate Change and Food Security for All: Is it Possible?

puffin

This week most of us felt hopeful as we heard President Obama announce new measures to respond to climate disruption. Although we have been hearing the discussion on climate change for a while, most people think of it as something that might unfold in the future. The fact is that climate change is here and is already altering the world as we know it.

Consider the case of the puffin: parents of baby puffins are bringing in food for them that they are not physically capable of ingesting. Why? Because the fish they usually feed on, hake and herring, are no longer found in the waters around them: the water is simply too warm for the fish to survive. So fewer baby puffins are surviving into adulthood. Their life patterns are also changing and the are coming in late this year to their summer habitats.

Meanwhile, humans too are faced with the challenge of feeding 9 billion people in a time of uncertain climatic conditions. The melting ice in the Antarctic could raise sea levels to an extent where China, India,Bangladesh, and Vietnam would lose millions of hectares of arable land and food production would fall. At the other extreme, higher temperatures threaten crop yield in the USA. A warmer climate also means an increase in disease and pests. The cloud of grasshoppers gathering in New Mexico is not from some movie set in the future, but happening right now.

The challenge is not just to create a more productive, climate resilient agriculture sector but also to ensure that all of our food is produced in a way that reduces pressure on a planet where everything is interlinked. If we look at discrete solutions we risk generating more problems: the effort to limit over fishing in the ocean by raising fish in farms, for example, has resulted in the destruction of mangroves and zones algae blooms that suck up oxygen and kill the fish.

The need is to consider the whole problem: whether we live in the Maldives or Mexico, on a farm or in the city, our lives are about to go in a direction different from what we known for centuries and the solutions we devise must take into account the needs of all the whole planet; humans, puffins and all.

And all this, without some coffee to help us along, because that too is likely to disappear as the climate changes.

#Farming Friday 17: Wishlist From An Indian Farmer

baingan

Ask someone what comes to mind when they hear the words “Indian Farmer” and the reply, in most cases, sadly is “suicides”. A while back they might have said “Green Revolution”,  but the myth of the Indian farmer planting a GMO crop and then taking a desperate measure when it fails, has taken firm hold of the Internet. (It has been debunked, for example, here ). Confronted by this, I try to  explain the facts on chronic indebtedness which follows farmers through generations, this information  is mostly ignored. But, here is a piece that one cannot ignore:  an Indian farmer writes about his hopes from the new government. He says, of farmers growing Bt Cotton, “No one forced them to do it. They chose to adopt GM cotton because it makes sense.”  The food system needs to make sense to people at both ends of it. Most often, however,consumers’ voices, specially of those consumers who are unfamiliar with hunger or chronic malnutrition in their own experiences are the loudest.It is time to listen equally to those who actually grow our food.

Revisiting the “eat local” Idea

market

I just came across this review of a book called “The Locavore’s Delusion”, and yes, it is a nod to that other book, in case you were wondering! The authors of the book tried to answer the question: why did we start eating a more global diet anyway? The article gives a summary of reasons that most people offer for opting to eat local: more tasty, nutritious, helps local economy etc , and the most often cited reason: it is good for the environment. This has been the subject of much discussion (some of which I wrote about here) and the point at issue is that the contribution to greenhouse gases comes more from the actual cultivation of crops rather than their transportation.

The answer the authors provide to the query, why did global food trade develop, is that it provides increased variety of foods, reduced prices and stability of supply. They also argue that efforts to counter this are really an effort to turn back the clock with negative consequences. If a region was hit by unexpected weather events or pest infestations and the crops failed, there would be no relief available if we functioned as closed off food islands. Indeed, they see the problem as being one of inadequate globalization where subsidies, trade barriers and other distortions are hindering an optimum situation of low prices and assured availability of food.

Some of the discussion here has been heard before but I liked the way the question was posed: why did we start expanding out of the local market? Perhaps we could ask the same question for the GMO question: why did we start developing them in the first place? Was it because some evil people were working up weird stuff in their labs and injecting it into food to try and rule the world like in some bad movie? No, it was because we need to tackle pests to stop crop loss. We will need it in the future to combat climate change. Imagine a flood event that submerges crops. Since genetically modified crops that could withstand the submersion were not planted, there is no food. But there is also no way to acquire it from anywhere else because food trade has given way to purely local markets. It could happen….

Farmers Respond to Climate Change

millet

As the last post mentioned,  the US government’s latest report on climate change takes note of the challenges that await farmers in the coming years. But, as we know, farmers are dealing with variable and unpredictable weather right now, so that the crops they grew and the way they grow them is also changing.How are they doing so, what are they changing?

One interesting aspect of the response to changes in climate has been the rediscovery and resurgence of neglected/marginal crops. Often, these would be crops indigenous to a certain area which required little tending and were, sort of, taken for granted. Now, their ability to grow in marginal areas has become an advantage. An example here would be the case of the lima bean in Kenya. This bean remains dormant in the soil, waiting for the rain and so can survive dry spells,so it has moved from being a marginal crop to the center stage of  cultivation.

“Climate Smart Agriculture”  which consists of ensuring food security, adaptation and mitigation (as defined by the FAO) is redefining farming in different countries. The success stories range from harvesting water to grow millet in the Sahel to adoption of rice production techniques to use less water by smallholder farmers in Vietnam; from carbon farming initiatives in Australia to reduction in the  contribution of Danish agriculture to emissions by better use of manure and lower use of inorganic fertilizers.

And what about American farmers? Some of them, it seems, see the disruption in climate as simply another weather pattern, but they are also aware of the  need to follow good practices on the farm to be able to deal with the weather patterns. This means that they are quick to adopt the climate efficient techniques suggested by the USDA: practicing no-till farming, planting cover crops etc.

Whether changes come by way of policy decisions , as responses to the threat to a way of life or as pragmatic reactions to constraints, all these changes  will add up to a better food system. But will they be enough to get us through the crisis ahead?

Technology On the Farm

Often we tend to think of technology as being too expensive/difficult to employ except on  a large scale. But one project in Ethiopia found that loading e-readers for extension workers made a big difference as they had access to a lot of material but none of the hassle of carrying around a load of stuff.

In Sudan, a simple SMS can alert farmers to rainfall forecasts enabling better preparedness for floods or, letting them know how much water would be optimal for their crops at a given time. Small steps with big results.

Smallholder Farmers Most Vulnerable to Climate Change

cofcl For some time now, we have been aware that coffee farmers have been facing the challenges of climate change; either from too much rain or from drought. Coffee crops are also being attacked by coffee rust which thrives in the warmer temperatures we are experiencing today. Colombia was one of the countries worst affected by this issue but the Colombian Coffee federation has invested on a large scale in rust resistant varieties, thus providing a solution and some hope for the farmers. In Brazil, large coffee producers have moved operations to cooler areas to combat the rising temperatures. But lost in all this is the small holder coffee farmer, often the supplier of the fair trade coffee we prefer as a better option for the planet.

While our choice at the cafe makes us feel we did the right thing, the reality might be different, with the farmer often at the losing end of a deal with middle men and has limited access to resources to deal with the problems facing coffee cultivation. This is an important consideration in any discussion on climate change: the bigger economies/groups with greater resources will at least have the chance to adopt some measures to combat the impact of changing climate; but is is those with the least resources and access, whether it is nations or communities within a country that are most at risk.

Also, can we acknowledge that climate change is not like any other problem that we have faced in the past? It is a challenge to the way we have lived on this planet for so long and its impact will be colossal so it is only logical that we employ all options to deal with this crisis. Those small holder coffee farmers facing the prospect of losing their livelihoods could benefit from solutions offered by biotechnology. In a better world, we would  be open to options that science can offer and not be held back by unfounded fears. At this point, the future looks pretty grim, we are going to need some coffee to deal with that!

Food Security and Ecology in India

ID-10042528

In India last year, there was an intense debate on the proposed Food Security Bill, centering mostly around the impact on the national budget and the mechanism of distributing extra supplies of food grains to consumers throughout the country. Parliament eventually passed the Bill but the question remains: is this really the food security initiative that will serve people best? For the rural population, which is primarily involved in agriculture, food security is not merely a matter of entitlement to a certain amount of cash or food grains; but is reflected in the existence of an available, accessible and assured source of food that will hold steady in the face of stresses and shocks to the food system. It is not just about hunger, it is about the ability to rely on a source of food in a stable way.

Traditionally, the food system for rural families comprises not only what they grow and the livestock they raise, but also what they extract from forests, streams and the surrounding landscape. The ecosystem can provide food directly (edible plants and animal and also medicinal plants), these can also be sold and the income used to purchase other food products; forests also provide firewood that is crucial for cooking (an adequate supply is required, for example, to cook proteins such as beans and meat which would help improve quality of diet). In terms of production, forests provide a habitat for pollinators, maintain/reduce soil erosion and fertility and mangroves and coastal forests reduce the impact of flooding to ensure stability in crop production and fish supply. Rural people, therefore, rely on the surrounding system for supplementing their diet as well as for their livestock and also to ensure that their crops can flourish. But this rural landscape and  the resources it offers also face degradation from overuse, pollution, deforestation all of which will be exacerbated by climate change. With the spread of urban living and tourism, rural populations without strong land rights are often shut out off lands to which they traditionally had access. It is in this context that a food security policy needs to be assessed. Can rural families count on an accessible, available and assured food supply?

On a broad scale, a balance has to be sought between conservation and production/consumption. Efforts at preserving and conserving the environment can sometimes lead to an artificial split in the landscape with certain areas marked for production and others for conservation. This negates the traditional integrated living patterns of rural people where forests and agricultural production coexist. By making an arbitrary divide in the environment, farmers are now excluded from access to resources that earlier supplemented their nutrition.

A recent World Bank report underlined that India would have to “value its natural resources, and ecosystems to better inform policy and decision-making.” This seems to be in accordance with what the Environmental Policy Report of 2006 which explained that “the dominant theme of this policy is that while conservation of environmental resources is necessary to secure livelihoods and well-being of all, the most secure basis for conservation is to ensure that people dependent on particular resources obtain better livelihoods from the fact of conservation, than from degradation of the resource.” How much of this translates into actual practice is another matter.

In terms of providing support to deal with stresses and shocks without further intensifying ecological degradation; the Food Security Act can be effective. If farmers could rely on this as a source of food, there would be less pressure to draw on an already threatened or depleted environment. This concern is brought into sharper focus as we face the challenge of climate change which would stress the ecosystem. All the effects of a policy that is blind to ecosystems will be further magnified by climate change. It has been estimated that there will a ten per cent extra increase in malnourished children world wide, as a result of climate change. India is particularly vulnerable, according to UNICEF, 1 in 3 malnourished children in the world live in India that makes future projections accounting for climate change of great concern. If food security policy assures them of at least a meal a day at school, that could have a big impact.

On the other hand, the Food Security Act is limited to a few crops and this has ecological implications as well. Due to the increased demand for these crops, farmers would find it profitable to opt for growing only a few major crops such as wheat or rice thus drawing more resources such as water to these two crops and reducing diversity in the production of food.

For an effective food security policy, ensuring access to ecosystem resources is crucial; it is not simply a matter of handing out grains/cash through a public system. An effective food security policy would view people and the ecosystem as integrated and design measures that work across sectors; so conservation/environmental policies would be devised in step with rural food security policy. It would recognize that food security also needs to be climate resilient and stresses brought on by climate change such as drought, and flood which impact access to food can be better managed by ensuring that production policies and conservation efforts are framed with the entire ecosystem in mind.

This post grew out of a Twitter discussion with @IndianBotanists and I thank them for their suggestion and appreciate their patience as this post came to fruition. (Image Courtesy:freedigitalphotos.net)

Can a Rice Gene Save the Banana?

r2

 

Can a gene from rice help combat the pathogen that threatens the extinction of bananas? That was just one of the many interesting issues featured in Dr. Pamela Ronald’s lecture at the SAIS Global Issues in Agriculture series. Dr. Ronald is a plant geneticist at the University of California, Davis. Many of us following the debate on GMOs  might have read her book, “Tomorrow’s Table”, co-authored with her husband, Mr. R.W. Adamchak, who is an organic farmer.

Speaking to a (mostly) non-scientific audience, Dr. Ronald explained in clear terms that growers have been trying to enhance desirable traits in crops forever. The older method of simply crossing Type x with Type y and waiting to see whether the hybrid plant had the desired trait . This method focused on the outward result but modification at the genetic level did take place but was unobserved. Genetic modification today is precise,  and efficient and enables quick and accurate results. In addition, it is backed by years of research data.

Why do we need genetic modification anyway? Consider, Dr. Ronald said, the case of the GM papaya. The papayas grown in Hawaii were attacked by the ringspot virus which devastated the crop, even moving the crop to another island did not help. Ultimately, the plants were “vaccinated” with a dose of the virus which enabled them to resist when the virus actually attacked. And so it is that we still have papayas in Hawaii. Perhaps a similar solution could be found for coffee rust? We will never know if we cannot try this option in the real world. Dr. Ronald spoke of her own work with rice: how a rice gene could possibly be used to battle the pathogen which threatens  bananas with extinction.

One possible application of genetic modification could be in building climate resilience in crops.Dr. Ronald shared her work on building flood tolerance in rice. In many parts of the world rice is grown in flood prone areas and with increased flooding possible from climate change; the development of a strain of rice which can stand water logging for up to 17 days as compared to the current maximum of 3 days is great news. But all these wonderful possibilities would take years to negotiate the stringent regulatory process and even then be opposed due to fear mongering. In that context, I was hoping to ask Dr. Ronald for her views on labeling of GMO products. But , sadly, there was not enough time; most of the discussion was taken up by two journalists from Germany, which, given that country’s staunch opposition to GMOs was interesting….

The main point to learn from this lecture was that the seed (around which so much of the storm is swirling) is but a small part in the whole process of growing food and we need to incorporate all options, technology and good agro-ecological practices to achieve sustainable development.

While I was learning all this; with ease, I would like to add, as Dr. Ronald is great at making all this scientific information accessible to those not from a science background; I wished more people could hear her, instead of being bombarded by myths of “dangerous farming” and GMOs killing bees.

#Farming Friday: Who Controls the Seeds?

One of the issues in the GMO debate that seems to concern people a lot is that of corporate control over seeds. In today’s Farming Friday, a  farmer talks who uses both GMO and non-GMO seeds talks about his choices and decisions.
