Through their unconscious actions, Women conserve the most important resources needed for sustainable development – forests, energy and water.

In my words, without putting natural resources in the picture, to conserve is to use frugally and cautiously. I’m saying today that women are much better at “using frugally and cautiously” natural capital, as compared to their male counterparts. In this case, conservation is the “wise use of natural resources.”

We use various natural resources on a daily basis, starting from food to the air we breathe. However, I will use the other resources that we put to use on daily basis at our homes, and have much more control over their use; water, electric energy and wood fuel. I’ll let you think about any other.

On average, men use more water that women in every activity that they undertake involving use of this resource. For drinking purposes, men are advised to drink three litres of water a day compared to women’s 2.2 litres. Even a pregnant woman is supposed to take just 2.4 litres a day, until they bare the child when they can increase intake to 3 litres (For your information, too much water is bad for your health). Now, whether we follow this advice or not, the fact is that generally men take more water than women.

Secondly, while a woman can comfortably use five litres of water to bathe, that is enough for a man’s head only. On average, men use more than ten litres of water when bathing, irrespective of their body sizes.

Think about this as well; given that a man is in the right mood to assist in the kitchen, especially with washing utensils, how much water would he use to wash five plates and five glasses plus a few forks? My answer is, whether under running tap or not, a man in the right mood of doing this chore would use much more water than a woman would.

It is the difference in these amounts that I call conserved water.

I do not want to go to figure facts about how much hydro-electric power we produce in our country, and how little this is to sustain all national requirements. What you need to know however, is that the current population size of people connected to electricity is a meager 20 percent – just about 7.5million of the 38million Kenyans- albeit insufficiently.

With all the rationing, you’d expect the figure to be somewhere at 70 percent! Now, women have proved to be better users of electricity.

It is the simple things that matter most; switching off lights in unoccupied rooms, switching off unused power sockets and unplugging unused gadgets. A man will leave his radio or television on while going to the market thinking that they won’t take long, but a woman will switch off everything. While cooking or ironing, a woman will most likely be more cautious not to leave the flat iron heating or food to burn on the cooker. You know this is waste of energy. And don’t tell me about society-roles-advantage here.

Over 90 percent of Kenyan households use wood fuel for various purposes. This is directly proportional to the extent of forest destruction in the country. Still, women have shown to be more conservative of the forests. I will not tell you that they use less firewood in cooking than men, not at all. I am thinking of a scenario where two people, a man and a woman have a task of going onto the forest to look for firewood.

Most likely, the man will carry an axe, but the woman will carry a machete/panga. It most likely is due to their physical abilities that when you watch these two people coming back home, one will be carrying/pulling almost a whole tree where as the other will be carrying smaller tree branches. The one who cut off small branches is the better conservationist.

I know what the man is thinking now; that women don’t do these things while thinking of conservation. I did not say they do. But through their unconscious actions, they conserve the most important resources needed for sustainable development – forests, energy and water.

The conserved forests aid in rain formation. Rain brings water and the conserved forests act as water catchment areas. They become the sources of the streams and rivers that supply us with water for our daily use. When the water reaches our homes, the women use it much more frugally, and enable other people to get their share as well.

It is the same waters from the forested catchment areas that are used to produce electricity, and women use this electricity better than men. Once again, it doesn’t matter whether they switch off all unused electric gadgets and sockets because they fear electricity-related accidents. The fact is that they end up conserving natural resources, and the challenge to men is whether they can do better.

German airports are employing bees to check their environmental impact. Beekeepers in Germany near airports are having their honey tested for toxins. All these unpaid bee workers have, in essence, reported back that there is not a significant problem with air quality, compared with other zones.

At Dusseldorf International Airport, the bees have reported that their honey exhibits the same toxin levels as those in a non-industrial area and better still, the honey is given away under the name of Dusseldorf Natural.

The usual main pollutants are nitrogen dioxide (NO2) and PM10, PM2.5 (small particulates). So how does this relate to Kenya? The answer could be supplied by Dr. Linsey C. Marr at Virginia Tech. Dr Marr has found that the running times in marathons are more affected by air pollutants  in the case of women than in the case of men. Dr. Marr reported:  “Although pollution levels in these marathons rarely exceeded national standards for air quality, performance was still affected.” And marathon performances? Now, they certainly are important.

Fertilisers, pesticides and hybrid high-yielding seeds saved the planet from an extra dose of global warming. That, at least, is the conclusion of a new analysis which finds that the intensification of farming through the green revolution has unjustly been blamed for speeding up global warming.

Steven Davis of the Carnegie Institution of Washington in Palo Alto, California, and colleagues calculated how much greenhouse gases would have been emitted over the past half-century if the green revolution had not happened.

The study included carbon dioxide and other gases such as methane emitted by rice paddies. It found that, overall, the intensification of farming helped keep the equivalent of 600 billion tonnes of CO₂ out of the atmosphere – roughly a third of all human greenhouse-gas emissions between 1850 and 2005.

The emissions were avoided because the green revolution boosted crop yields – for instance by promoting hybrid varieties that had higher yields, and through widespread distribution of pesticides and fertilisers. This meant that more food could be produced without having to slash vast swathes of forest to expand farmland.

Augustine Nsada has become famous in his trading centre of Kasambira in Kamuli district of western Uganda, albeit for doing what many of his folks know how to do already.

Thirty-year-old Nsada gained popularity for being the only commercial producer and supplier of plantain bananas last year when the area was facing a severe drought. The bananas are a staple food crop in most parts of Uganda, but production has been declining in recent years.

Using largely abandoned traditional practices of mulching and applying compost to his bananas, Nsada managed to continue producing badly-needed food. The composting is effective, but it is used with few other crops.

The people of Kasambira and much of Busoga region in eastern Uganda had till 2009 been self-sufficient in food, growing plenty of maize, sweet potatoes and beans. But a six-month drought, starting in April 2009, altered seasons and delayed rainfall. It took many poor farmers by surprise: they had experienced nothing like it for years. The serious food shortage that affected households forced hundreds of thousands of people to buy food from traders instead of being able to rely on the seasonal crops they grew themselves.

Claims that climate change caused the drought

The Ugandan Ministry of Agriculture attributed the unexpected drought to climate change. While there is no conclusive evidence of this, recent reports, including those from the Intergovernmental Panel on Climate Change, point to the weather changes already apparent in poor countries like Uganda. A study by Oxfam in 2008 concluded that the erratic rainfall seen recently in Uganda was consistent with scientific predictions of the effects of man-made global warming, while cautioning that weather patterns in Africa are still relatively poorly understood.

Whatever the origin, the impact was devastating. Last year’s drought in Uganda is estimated to have affected up to five million people, in a nation of 31 million.

Plantains are not particularly nutritious compared with beans and maize. But plantain consumption is a strong part of Ugandan culture, which insists that any serious meal must include steamed plantains.

Nsada managed to continue harvesting the plantains for home consumption and for sale throughout the drought. Plantains will grow all year round with moderate rainfall and sunshine. But plantain growing is demanding work, and not many people are ready for the laborious mulching and pruning required.

“During the recent drought, many people looked to me for food because they had consumed all their reserves,” he said.

Cushioning families

Abdu Waiswa, who runs a maize mill in Kasambira, agreed that annual crops like bananas and cassava can help to cushion families against unexpected weather changes such as droughts.

Dr. Andrew Kigundu, a banana researcher at the National Agricultural Research Institute (NARI) in Kawanda, near Kampala, says bananas store water in their stems as well as producing fruit all year round, making them a vital source of food security during dry spells. But he says that, ‘Bananas have succumbed to extreme weather changes largely because most farmers have abandoned the old traditional practices such as mulching”.

‘Mulching not only prevents fast loss of moisture from the soils, but also minimises tillage that destroys the crop’s root system,” Dr Kigundu says.

While much of the country has largely recovered from the effects of last year’s drought, the government has been encouraging people in its broadcasts to store cereals so that events like the drought find them better prepared.

But the increasing frequency, length and sudden onset of droughts and floods in Uganda and its neighbouring countries in recent years has meant it is difficult to estimate just how much food people need to store when they are already poor.

David Isabirye, a resident of Nalinaibiri near Kasambira trading centre, said he had kept some food for his family last year, but was forced to sell some to pay his children’s school fees.

Uganda’s State Minister of Agriculture, Henry Bagiire, says the government is pursuing several measures, including encouraging the growing of annual crops.

Annual crop production facing challenges

But the shift towards annual crop production faces many other challenges. Farmers usually prefer seasonal crops, which normally guarantee them two annual harvests, have a longer lifespan than the highly perishable plantains, and are eaten by more people outside Uganda.

Pests are another problem. Scientists estimate that over the past ten years Uganda’s banana production has halved because of the devastating effect of the banana wilt disease. Cassava, another important source of carbohydrates for most communities, has been greatly affected by the cassava brown streak virus. Scientists from NARI say they are close to developing disease-resistant varieties.

Land scarcity is also a factor. Widespread sugarcane growing has taken up much of the land previously used for food production. High population growth rates mean portions of land becoming increasingly smaller, which when cultivated continuously quickly lose their fertility.

Nsada also says the lack of political leadership in the area to mobilise people for production is one of the problems that has deepened vulnerability during weather-related disasters. ‘The government needs to follow its words of encouraging people to save the environment and grow more food with concrete actions and support that ensure people replenish their soil fertility,” he says.
