A burning hunger June 24th, 2018 by

Towards the end of the dry season many families across the African savannas have exhausted their reserves of stored cereal crops. Vegetables are hard to come by in local markets. Bush meat is one way for rural people to supplement their meagre diet with protein during the well-named lean or hunger season. This is why development organisations have struggled for decades to curb the destructive practice of setting the bush on fire to hunt small wildlife.

One option to ensure some food and income during the lean season is to grow cashew and mango trees. But with increased labour costs and insecure markets, it is difficult for farmers to properly maintain their planted trees. Slashing the weedy and bushy undergrowth is often only done late during the flowering and fruiting season, by which time bush fires set by others may have spread into and destroyed entire plantations in no time.

Increasingly, development organisations are starting to realise that integrated farming systems and local value addition to food are the way forward. In a recently published video on the Access Agriculture video platform, the Beninese NGO DEDRAS neatly shows how growing groundnuts and soya beans in cashew plantations helps farmers produce a nutritious crop during the lean season, and thus discourage damaging bush fires. DEDRAS also made a training video with rural women on how to make cheese from soya, a good example of adding value.

In addition to tree crops, such as mango and cashew, farmer also manage other local species, such as nĂ©re (Parkia biglobosa) and the karitĂ© or shea nut tree (Vitellaria paradoxa). These wild indigenous trees, distincive features of the savanna, also provide fruits and nuts during the lean season. NerĂ© and the shea nut tree have grown here for thousands of years and are relatively fire-resistant. Traditionally, nĂ©rĂ© seeds are dried, cooked and fermented to make “soumbala”, a local equivalent to bouillon cubes that brings taste to many dishes. But with an increased need for fuel wood, more nĂ©rĂ© are being cut down. While the fuel wood crisis has not received the attention it deserves, nutritionists have taken notice and have come up with a way to use fermented soya beans as a replacement for the local soumbala. This practice has been captured by the NGO AMEDD in Mali in a nice farmer training video, also hosted on the Access Agriculture video platform.

In an earlier blog, Jeff wrote about his experience with grasscutters in West Africa. Declining populations in the wild, along with the strong and continuing demand for meat, have inspired rural entrepreneurs to develop alternative sources. Across Africa one can witness how mainly women and youth have set up grasscutter, poultry, rabbit and other small livestock businesses.

The many training videos on small livestock, intercropping with legumes, and rural food processing offer viable alternatives to the hunting for bush meat. These enterprises may eventually prove more effective in reducing bush fires than lecturing rural people about their adverse environmental impacts. Positive solutions are always better at promoting behaviour change.

Robbing land from the sea March 25th, 2018 by

The low-lying Netherlands is famous for its polders, the land behind the dikes, reclaimed from the sea. Beginning about 1000 AD, people made dikes, or earthen dams, to protect communities from flooding. At first the water was simply drained through canals, but with time the land in the polders subsided, and by the 1400s water was being pumped out with windmills. Thanks to hard work, investment and some clever engineering, people still live in and farm the polders.

Much of Bangladesh is also right at sea level and densely populated. So why doesn’t Bangladesh have polders too? I wondered out-loud during a recent visit last October.

“But we do! Bangladesh has many polders,” my colleague Salahuddin retorted. He explained that there was a string of some 123 polders over much of southern Bangladesh, an area where several large rivers cut the delta into finger-like strips of lowland.

The polders were built between the 1960s and the 1980s, first by the provincial government of East Pakistan, and later by the Government of Bangladesh, after independence from Pakistan in 1971.

Each polder is ringed by a low earthen embankment (basically a dike), sometimes just two meters high and made by hand. The roughly oval-shaped polders are dozens of kilometers in circumference.

The Bangladeshi polders are drained by an ingenious network of canals, radiating like veins from the center of the polder to the edge, where the flow of water is controlled by a sluice gate in the embankment.The sluice gate is a concrete structure with metal doors that can be raised by a hand-crank to let the water out during the rainy season, and lowered during the dry season to keep out the saltwater.

Originally the wetlands of the delta region had been sparsely populated by fisher-farmers who grew low yielding rice varieties that tolerated brackish water. The polders soon became attractive places to live and settlers trickled in. The people who were born in the polders tended to stay there and so populations increased.

Some of the polders have benefited from some sort of project, and have been reasonably well managed. By 2018 the better polders are like gardens, with comfortable farm houses surrounded by shimmering green rice fields.

The polders have had their share of troubles. Sometimes one of the rivers changes course, depositing a bank of silt next to the sluice gate, so the water inside the polder cannot drain out.  Other problems are man-made. Loggers float timber down the canals, and when the logs reach the sluice gates, the workers take the easy route to the river. Instead of hoisting the logs around the sluice gate, the loggers force the timber through the delicate metal gates, twisting and denting them so they no longer open and close. Wealthy, powerful people sometimes block the drainage canals to raise fish in them. Or they string nets over the canal to catch fish. But this slows down the flow of water, allowing silt to settle and eventually block the canal. The canals are as wide as a highway, and can be just as difficult to maintain. So once the drainage canal stops working, villagers are unable to open them up again without help from outsiders.

The polders are essentially a government mega-project, which sounds at first like a recipe for disaster. But as one drives along the top of a polder embankment, the muddy river on one side and the tidy green fields and villages on the other, it is hard to ignore the fact that the government got something right.

Ironically, country that is flooded during the rainy season may be completely dry a few months later. Various initiatives are now promoting dry-season irrigation for high value crops besides rice, and the farmers in the polders are avidly buying motorized pumps. In many places the rich, black earth inside the polders is now producing two or three crops a year of rice, mung beans, mustard, watermelon and vegetables.

Such changes in the farming system are creating more wealth for the farmers in those polders that are well run. But it will take collaboration, for local government to protect the canals and embankments, for the private sector to provide farm supplies and buy the produce and especially for innovative farmers, to continue re-inventing the agriculture of this marvelous, human-made environment.

Floating vegetable gardens March 11th, 2018 by

For much of the year Bangladesh appears more water than land. It can also be a chaotic place. Yet such impressions are misleading, and something I wanted to counteract with a genuine admiration for how people make the best of often difficult circumstances. Colleagues commented on my positive outline when I wrote about innovations in rural extension, in a book published in 2005. More recently, I’ve been reminded about the resilience and creativity of farmers after watching a video on floating vegetable gardens, now available on the  Access Agriculture platform.

The video is nicely made, with strong visual shots and compelling interviews with farmers. The dreamy traditional music carries you along in the wake of a wooden boat steered by a Bangladeshi farmer on a shallow, temporarily flooded area.

It takes a lot of work to make a floating vegetable garden, but the video reveals an amazing abundance of crops tended by farmers. For years, Bangladeshi farmers have turned two major recurring problems into an opportunity. The land lost to floods during the annual monsoons is used to grow crops; and the world’s worst aquatic weed, the water hyacinth, is turned into compost.

Scientists have tried for decades to find ways to control this weed, including the release of weevils that feed on its leaves. Governments and local authorities have tried in vain to mechanically remove this weed using heavy machinery, creating mountains of water hyacinth on the banks of rivers and lakes that no one is quite sure what to do with.

In the video, farmers in Bangladesh show a sustainable alternative. Instead of laboriously removing the bulky mass of water hyacinth, the weeds are left in place. A long bamboo pole is placed on top of a thick matt of water hyacinth and with a hook the water hyacinth is pulled from both sides of the bamboo towards the bamboo pole and compressed to make a compact plant bed. After 10 days the compacted leaves and roots start to decompose and a new layer of water hyacinth is added. Floating beds are about two meters wide and vary in length; some are as long as 20 meters.

In the meantime, back home, women have started to grow vegetable seedlings in round compost balls. Once the plants are old enough the gardeners carry them on the boat to their floating garden beds, and insert the compost balls with seedlings in the plant bed. Farmers grow okra, various types of gourds, leafy vegetables, ginger and turmeric. The video also shows how some innovative farmers even connect two floating beds with trellises made of bamboo and jute rope to grow yard-long beans.

Farmers across developing countries, and Bangladesh in particular, have a wealth of knowledge. The many training videos hosted on the Access Agriculture platform pay tribute to these farmers and allow them to share their knowledge and experiences across borders. At Agro-Insight we celebrate these respectable farmers in our weekly blog stories. We hope you enjoy reading them as much as we enjoy writing them.

To fence or not to fence February 25th, 2018 by

Fences reveal a lot about rural communities. They show  how farmers make good use of available materials, but they can also uncover social tensions. Reading fences and understanding what they do and represent tells you a lot about how people work and live.

In the country-side of Kenya, farmers have a long tradition of fencing their farm with wooden poles. While this practice stems from a time where trees were abundant, competition with fuel wood is gradually changing this practice towards more inclusion of living plants.

In some parts of East Africa, fences contain the so-called pencil plant (Euphorbia tirucalli), grown in Europe as an ornamental. The aim is to discourage potential intruders, particularly those trying to steal livestock.  The fragile branches of pencil plants break easily, releasing a white sap that can blind people when the juice gets into their eyes.

In Egypt, farmers protect their maize from grazing animals by surrounding the field with a row of nightshade (from the same plant genus as potato and tomato). As with Euphorbia, the nightshade’s leaves contain a toxic juice. Farmers can restrain their own animals from grazing afar, but can’t be sure their neighbours do the same. And once cattle get into your maize field, the damage can be huge. A small investment in fences prevents disputes with your neighbours about who pays for the losses.

But fences often do more than keep animals out. Stone walls in Guatemala often contain sisal plants. Without reducing the land available for grazing animals, the space taken up by the fence is used to grow this valuable plant that provides farmers with fibre to make ropes. By diversifying crop, livestock and plant species on farm, farmers ensure a steady supply of what they need to live from their land.

At the highlands of southwest Uganda, a local farmer, James Kabareebe, showed us how he plants Calliandra around his fields, an agroforestry practice widely promoted by projects in the 1990s. Prunings of this leguminous tree are used as mulch to enrich his soil with nitrogen. And above all, it provides the necessary organic matter to soils on sloping land that are highly vulnerable to erosion caused by tropical downpours.

At times, living fences also point to a level of social injustice. Customary land rights benefit male community members, while women are often left to struggle to grow food on smaller plots or on less fertile soils.

In parts of Mali, women have negotiated with their men to grow a high value crop along the border of the field. The juicy, red flower heads of the roselle or bissap plant (Hibiscus sabdariffa), which is native to West Africa, provide a good source of additional revenue for rural women.

Fences across the world give us insights into how people manage their land. They are like a signature, revealing a little about how people relate to the land, and to each other.

The ice harvest April 23rd, 2017 by

Ice was once a natural resource of some value, harvested, processed and sold on international markets. The ice harvest has vanished, but not before evolving into our modern food chain.

In 1805, the 21-year-old Frederic Tudor was at a party in Boston, when his brother William playfully suggested that ice from nearby ponds could be cut and sold to wealthy customers in the Caribbean. Frederic, later to be known as the “Ice King”, seized on the idea, and the following year took a ship loaded with ice to sunny Martinique, where he taught the owners of the finer hotels how to make and sell ice cream.

The ice cream sold for a hefty price, but the ice itself soon melted, leaving Frederic with a staggering loss of $4000. Not one to be easily discouraged, he learned from his expensive lesson by experimenting with different ways to make the ice last longer. He compared types of insulation, including straw, wood shavings, and blankets, and designs for storage facilities until he had perfected an ice depot that could keep 92% of its inventory frozen for a summer season. Once he had succeeded, Frederic’s business and reputation soared.

Ice mover NSmallFor years, ice harvesters improvised techniques with pickaxes and chisels, aided by horses wearing spiked shoes, to avoid slipping on the frozen lakes. This was usually good enough to gather enough ice to be stored for sale in the summer in northern cities. Then in 1824, another Massachusetts man, Nathaniel Jarvis, invented a horse-drawn ice cutter, with parallel blades that would cut ice from frozen ponds into blocks of standard sizes, such as 22 by 22 inches (56 centimeters). This innovation allowed blocks of ice that could be loaded tightly onto a ship, without spaces in between. The ice was less likely to melt or shift in transit, and the ice trade took on a new life.

Ice began to be shipped to Charleston, New Orleans and other southern cities (especially to chill beer and preserve fish during the long, hot summers), but in one bold experiment in 1833, Tudor shipped 180 tons of ice to Calcutta, where he built a large ice depot to house his product. Residents of India could now buy an insulated box, and stock it with a block of Yankee ice that would keep food and drinks cold for days.

4380 keeping the fridge cool with iceBy 1856 over 130,000 tons of ice were being cut from ponds around Boston and shipped not just to India, but also to Latin America, the Caribbean, China and the Philippines.  But that same year, spurred by the profits to be made from ice, a British journalist, James Harrison, invented a practical, coal-powered ice compressor in Australia. “Natural ice” (cut in the wild) and “plant ice” (from factories) competed with each other in an expanding market. In the 1800s, some railroad cars and ships were fitted with ice-holding compartments that allowed fresh meat and other perishable produce to be shipped long distances.

At first, consumers preferred natural ice, believing it was cleaner and longer lasting, and it wasn’t until 1914 that plant ice in the USA gained dominance. Relatively inexpensive electrical refrigerators came onto the market in 1923. Once consumers had refrigerators, they no longer had to buy ice.

ice bhanAfter a century of lively commerce, the spectacular long-distance and large-scale trade of natural ice finally began to decline and eventually collapsed in the 1930s. However, the ice trade has left the modern economy with a legacy: the commerce in fresh food which continues to this day, although it is now based on refrigeration, not natural ice. And of course there is still a niche market for factory-made ice, sold for picnics, and (especially in developing countries) to fishmongers and other small-scale food dealers.
The ice trade also led to another innovation, the ice box, which allowed homeowners to keep food fresh, stimulating the trade in produce from countryside to town. Modern supermarkets with ice cream, frozen fish and fresh meat presuppose that the consumers have a refrigerator at home. Today, tropical countries like Ghana export mangos and papayas to Europe and North America. Because of refrigeration in Central America, more farmers are able to sell fresh produce to large, new supermarkets in cities like Tegucigalpa and San Salvador.

You can now find tropical produce in refrigerators around the world, and in a sense it started when a student at Harvard joked with his brother about shipping frozen pond water to the Caribbean.
