Efforts to thoroughly study the role that plants play in climate change mitigation are increasing. Most researchers focus on the promise of large, leafy forest trees to help remove carbon from the atmosphere; for example Lal (1998) in India, Chen (1999) in Canada, Zhang (2003) in China, and Monson ( 2002) in the United States. This is because, generally speaking, the bigger the plant, the more CO₂ it absorbs – click here to see how plants do this – and trees are the most obvious large plant species. However, there are some very large non-tree plants in the world and increasing evidence points to a surprising grassy climate change warrior: bamboo.

One species of bamboo, the guadua angustifolia, found in Venezuela, Ecuador, and Colombia, has been shown to grow up to 25 meters in height and 22 centimeters in diameter, with each plant weighing up to 100 kilograms (Rojas de Sánchez, 2004). This doesn’t match the stature of many trees, but it is still big enough to be significant. It is not all about size, however. How fast a plant grows has a part in determining how much CO₂ it can absorb in a given time. In this respect, bamboo wins hands-down: it grows faster than many trees, growing up to 1.2 meters per day. In fact, bamboo holds the Guinness World Record for the world’s fastest growing plant.

Much is written about the need to reduce deforestation and replant the forests that have been logged for human use and economic development. This is because trees are needed for fighting climate change and vital to the very survival of the planet. But what is it exactly that makes trees and other plants so special?

Climate change is caused, at least partly, by man-made emissions of greenhouse gases which accumulate in the Earth’s atmosphere and trap heat. The Intergovernmental Panel on Climate Change (IPCC), set up in 1988 by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO), and endorsed by the General Assembly of the United Nations, is the leading international body for assessing this phenomenon.

In their most recent Assessment Report from 2007, the IPCC reported that carbon dioxide (CO₂) is the most significant anthropogenic greenhouse gas, both in the sense of the amount of heat it traps and the quantity that is released into the atmosphere (mainly from the burning of fossil fuels). Forests are very effective ‘carbon sinks’, extracting CO₂ from the atmosphere and keeping it locked away for long periods of time. Therefore, some of the key strategies to alleviate the causes and effects of climate change recommended by the IPCC include efforts to reduce deforestation, while simultaneously increasing afforestation and reforestation: planting of forests where none were before and replanting areas where forest has been removed, respectively.

The Spring 2013 issue of the Tropical Agriculture Association‘s (TAA) Agriculture for Development journal featured a report on food security and livelihoods of the rural populations of Guatemala by INESAD’s Ioulia Fenton. The paper summarizes the results of fieldwork research carried out by Ioulia in the province of Solola that focused on rural-urban linkages approach to development. The report makes practical recommendations for projects and policies that could begin to tackle some of Guatemala’s worst poverty and malnutrition problems. These include focusing on more sustainable farming methods, reverting to agricultural production geared for the local (rather than export) markets, and setting up knowledge transfer initiatives to teach people to conserve fresh produce by drying, salting or pickling it.

The article is available for free exclusively to Development Roast readers and can be downloaded from Ioulia’s Academia.edu site:

Today, the popular anthropology site PopAnth published an article by INESAD’s Ioulia Fenton in which she reflects on her time living and researching in Guatemala and the shopping experience that helped her feel more connected with food and the local people who produced and sold it.

Shopping for the human connection?

By Ioulia Fenton

In Guatemala I was addicted, truly addicted, to my morning regimen. No, it wasn’t a catch up to the day’s news on my iPad with a cup of coffee from Starbucks. Nor was it my favourite bowl of cereal or brand of orange juice. It wasn’t even a luxurious shower or a sleep-in. It was something much more sacred: a daily experience that allowed me to indulge in what makes us human — connections with others. Read More »

South Korea’s development over the past half-century has been one of the biggest successes in the world. Measured in terms of either economic wealth, or the Human Development Index (HDI) which considers factors such as education and life expectancy, South Korea’s rise has been phenomenal. The country which is currently renowned for hi-tech companies such as Samsung, and for being the home of ‘Gangnam Style‘, was, just 50 years ago, suffering from the aftermath of a bloody civil war and had a Gross National Income (GNI) per capita of just US$64.

A brief summary of the South Korea’s recent history sets the scene. Prior to World War II, Korea was ruled by Japanese imperialists. After the war, Japanese rule was replaced by the Soviet Union in the northern part of the country and the United States (U.S.) in the south. The northern rulers invaded the south in 1950, starting the three-year long Korean War which ended in the country being divided into North and South Korea. Kim Il-Sung took up the presidency of North Korea while South Korea came under the dictatorship of President Rhee Seung-Man. A military coup in 1961 led to General Park Chung-Hee taking the rule from President Rhee, and South Korea started the journey to rebuild itself. The results are astonishing: in 2011, the country’s GNI per capita was over US$28,000, putting it in 15th place in the list of world economies, and it also ranked 15 out of 187 countries in the Human Development Index that year.

The Earth’s climate is changing and the vast majority of the scientific community as well as the public is now convinced that human activity is contributing significantly to this phenomenon. The underlying cause is an increase in the concentration of ‘greenhouse gases’ in the Earth’s atmosphere, such as carbon dioxide, which is released when fossil fuels are burnt; nitrous oxide from chemical fertilizers; and methane which is produced from activities like rice farming and livestock production. These gases trap heat in the atmosphere, leading to the ‘greenhouse effect’ – a rise in the average global temperature which leads to melting ice-caps and therefore rising sea-levels. Additionally, the change in the atmosphere makes the climate more unpredictable, increasing the incidence of ‘freak’ weather events such as hurricanes, floods and droughts (‘global weirding’). Regardless of what is causing the climate to change, preparations need to be made to cope with the consequences as they will impact on many aspects of life. One of these will be the world’s food supplies and food prices, since agricultural growing conditions will change in certain places, affecting the type and quantity of crops that can be grown. This in turn will affect people’s ability to buy and otherwise access food.

However, right now, the biggest impact of climate change on food supplies and food access does not come directly from the changes in climate. Instead, it comes from one of the ways in which we are trying to stop climate change: biofuels. ‘Undercovering Undernutrition Part II‘ showed that the growing demand for biofuels (mainly from western countries) means that in some areas biofuel crops are being grown preferentially over food crops due to their profitability. A 2010 report by the Institute for European Environmental Policy (IEEP) reported that European countries have chosen to meet the European Union (EU) legal requirement of including 10 percent of renewable energy in all transport fuels by 2020 by importing biofuels from places such as Indonesia, Brazil, and some African countries. One of the results, reported by The Guardian newspaper, is that the land acquired over the past decade for growing biofuel crops could have produced food for a billion people. This has led to increased food prices, leading to more people being unable to afford food and therefore going hungry. Read More »

Fifty five years ago, archaeologist, engineer and geologist Kenneth Lee discovered the ruins of an ancient civilization in the region of El Beni, in the northeast of Bolivia. The sophisticated technologies that were revealed by the excavated remains fascinated the academic community. One man in particular has spent the past several years developing an ancient agricultural system of camellones, used by this civilization, for modern use. This is a system that uses elevated fields, channels of water and aquaponics (cultivating plants and fish in the same water source) to protect crops from flooding, whilst fertilizing these in a natural way and increasing productivity compared to traditional industrial farming methods. The model has proved so successful in El Beni that the non-governmental organization (NGO) Oxfam has applied it in many African countries.

Today, to kick off Development Roast’s brand new ‘Bolivia’s Best’ interview series, we meet Oscar Saavedra, a Bolivian agroecologist and one of the founders of the Kenneth Lee Foundation who directs the camellones initiative under his own NGO, Amazonia Sostenible (Sustainable Amazonia) as well as his own business, Amazonia Services.

In 1957 the remains of a civilization from 3,000 years ago were discovered in El Beni, a lowland region in the northeast of Bolivia (see map below). This civilization was found to have a highly productive agricultural system which involved the construction of camellones (ridges). These were elevated fields, built to be above the height of the floodwaters, surrounded by channels. This produced a method of irrigation that protected crops from flooding whilst increasing the fertility of the soil. In the wet season, the rainwater collected in the channels, preventing the crops from being washed away. The water could then be stored and used to water crops in times of drought. This system was designed specifically for the ecosystem of the region which is particularly prone to flooding. Read More »

The world’s farming and transportation sectors are some of the biggest contributors to global warming and climate change since they emit around 14 percent of total global greenhouse gases each. Emissions are counted mainly from agricultural production and from the fossil fuels burned in road, air and sea freight, respectively. However, the two are also increasingly interlinked because of rapid growth of international trade in agricultural goods—such as foods, natural fibers and bio-fuels—over the last few decades. Agriculture’s impact on atmospheric pollution is rising because of the energy needed to move agricultural products between more and more countries around the world.

In theory, international trade is a good thing because it can reduce the price of goods for consumers and increase sales for producers, making everyone better off. However, this is a purely economic perspective that does not take important environmental issues into consideration. While goods will always continue to flow across national borders, if we are serious about reducing global greenhouse gas emissions and halting climate change, then we need to make sure that they do so in the most environmentally sound way possible.
