Latest on global warming


Our politicians and environmental activists loosely throw around the term, “global warming” to indicate the recent discoveries of a changing pattern in climate.
They cite instances of years with exceptionally high temperatures as well as an overall warmer temperature. While this is generally a well-accepted assertion, many climatologists will claim that we are going through a global cool down.
The evidence for this includes record droughts and very low temperatures.
While there is no definitive answer as to which side is correct, it is clear the southern parts of the country — Masvingo, Matabeleland and Midlands -have suffered the effects of global warming.
Armed with this truth, it looks as if environment is an idea whose time has come. Government statements on the need to preserve the environment are common place.
There are massive schemes for afforestation. Last December, thousands of seedlings were planted when a group led by one Phillip Mataranyika and Environment minister Francis Nhema embarked on a sponsorship walk to help regenerate the country through planting trees.
Zimbabwe has been praised all over the world for what it has done to preserve the rhino and elephants and 16% of our land mass is now protected national parks and wildlife sanctuaries.
There are demands to strengthen their protection and increase their area.
Political parties’ manifestoes take care to mention the importance of environment.
But there is a major problem with this entire range of activities and concerns: they do not appear to be based on a holistic understanding of the relationship between environment and the development process in this country.
The programmes are ad hoc, without clear priorities, and there is too much of a policeman’s attitude.
They seem to be based on the belief that concern for the environment essentially means protecting and conserving it, partly from development programmes but mainly from the people themselves.
There is little effort to modify the development process itself in a manner that will bring it into greater harmony with the needs of the people and with the need to maintain ecological balance, while increasing the productivity of our land, water and forest resources.
The post-independence political debate has centred on two major issues: equity and growth.
The environmental concern has added a third dimension: sustainability. Zimbabwe’s biggest challenge today is to identify and implement a development process that will lead to greater equity, growth and sustainability.
The environment is not just pretty trees and wildlife, threatened plants and ecosystems. It is literally the entity on which we all subsist, and on which entire agricultural and industrial development depends.
Development can take place at the cost of the environment only up to a point. Beyond that point, it will be like the foolish person who was trying to cut the very branch on which he was sitting.
Development without concern for the environment can only be short-term. In the long-term, it can only be anti-development and can go on only at the cost of enormous human suffering, increased poverty and oppression.
Zimbabwe may be rapidly approaching that point.
But, when you really take a long, hard look at international politics, you will notice the US has reached where it is at present due to its high consumption of fossil fuels. Zimbabwe does not really have a political party that focuses on the environment completely.
When there was a hue and cry about trees in the last few years, it was mainly due to direct threats to livelihood like what happened since the launch of the fast-track land reform in 2000.
In Europe and the US however, the environment is something that can be actually considered an active threat to economic progress.
In Zimbabwe, awareness in people at the grassroots level and the higher echelons of power about the importance of the environment is almost negligible.
With rising poverty, political squabbles in the inclusive government, health issues and unemployment taking priority; no party actually finds environmental issues an adequate plan to gain votes.
Other countries are earmarking varying amounts of their budgets to green growth. At last count, Zimbabwe has devoted nothing to the same aspect of green development.
Global warming affects all of us uniformly even if one country uses less or if the other uses more.
Rising sea levels can literally flood low lying areas of Zimbabwe in Muzarabani and Zambezi Valley, along with the increased incidence of droughts, floods and famines in Matabeleland region among others due to climate change and continued emissions from developed countries like the US.
With the economic boom in Zimbabwe since 2009, it will very soon become necessary for Zimbabwean political parties to take an active interest in the problem.
At present, the green drive to reduce emissions, recycle and conserve is being run by a mish-mash of active dynamic NGOs.
But that is not enough. Unless Zimbabwe finds a way to raise awareness at grassroots level and includes green policies in every aspect of its current development, it could very soon find itself losing its natural resources due to simple hard-headed ignorance

Government must increase the number of trees planted per year

tree planting.jpgGovernment says it is targeting to plant 20 million trees between this year and the end of next year as it seeks to ensure that the country’s natural resources remain intact.

The target is an increase from 10 million trees set last year and has been revealed at a time the country is preparing for the National Tree Planting Day which falls on the first Saturday of December every year.

The Minister of Environment and Natural Resources Management, Cde Francis Nhema said the focus of this year’s National Tree Planting Day is the impact of climate change and the need to realise that the salvation of the country from these effects lie in the way in which natural resources are conserved.

“We are looking at the drought situation and we are taking cognisance of that our natural resources have a bearing on what we do in terms of our everyday lives,” said Cde Nhema.

Minister Nhema said government will ensure that natural resources are kept intact through planting of trees which reduce risks of floods, mudslides and desertification.

He added that each province is required to double the number of trees it planted last year in order to meet this year’s target.

The National Tree Planting Day, which will be held at Nyamandlovu in Umguza District, is expected to be officiated by the Head of State and Government and Commander-in-Chief of the Zimbabwe Defence Forces, President Robert Mugabe.

This year’s event will be running under the theme, “Grow and Conserve Trees-Sustain Livelihoods,” and the tree of the year is Red Mahogany whose botanical name is Khaya Anthotheca.

Zimbawe on the verge to be a desert

ThereA report compiled by the Met Services using 30 years' data collected at stations at Belvedere, Harare, Bulawayo Goetz, and Beitbridge illustrates that weather extremes are the source of the problems. For the three sites presented, rainfall data shows no consistent trend indicating that changes in temperature and weather patterns were affecting the frequency and severity of rainfall, droughts, floods, access to water and the use of land.

Key findings of temperature changes indicated that:

1) There is a consistent trend of an increase in the occurrence of maximum temperature extremes at all the three stations

2) The chance of minimum temperatures being in the lower 10th percentile declined during the period

3) The observed rate of warming averages 2C per century, and as high as 2.6-2.7C per century at Beitbridge and Bulawayo

4) The number of cold days was observed to be decreasing at a rate of 14-17 days per century, whereas the number of warm days was increasing

5) The study indicated that 2C temperature rise would adversely affect the size of the area suitable for sorghum production in the country (from a simulation model)

"Zimbabwe like most other African countries will be the least prepared to cope with climate change. The threat of increased global warming associated with the release of greenhouse gases is real. Harare and Bulawayo have experienced a warming of about 2 degrees Celsius in the last 30 years and precipitation patterns also show a reduction of 30 percent in rainfall," Ms Chasi said.

She said the findings by the Met Services also showed that floods and droughts in the region are gradually increasing in number and frequency.

The study also indicates that:

i) Water resources are expected to dwindle

ii) The evergreen forests of the Eastern Highlands of Zimbabwe may be reduced to seasonal forests

iii) Southwest Zimbabwe may produce desert conditions

iv) Maize yields are likely to decrease considerably

v) Climate change may negatively impact on our efforts to achieve sustainable development

vi) Climate change may lead to declining water resources, reduced agricultural productivity, spread of vector-borne diseases to new areas, high risks to forests (outbreaks of fires), drop in fish population and increased flooding from sea level rise and heavier rainfall

Zimbabwe in the just-ended rainfall season experienced weather conditions, which were highly unusual and unprecedented in many areas. In the first half of the rainfall season (Oct to Dec), the rainfall in some parts of the country was the highest on record while drought conditions continued to worsen in the second half -- January to March.

There is nothing similar in recorded weather history to rainfall recorded in Zimbabwe last December. Since 1987, Zimbabwe has recorded six warmest years and this is consistent with a warming trend, which was being experienced in other parts of the continent and elsewhere in the world.

The level of one of Bulawayo's major water supply dams, Umzingwane has been declining since 1977,the 80s, the 90s and onwards in the 2000s owing largely to extreme weather changes -- severe droughts coupled with flooding in the others years.

Climate experts say Africa will be hit hardest and earliest when it is the rich industrialised countries in the North that are responsible for 75 percent of green house gas emissions.

Africa only emits about 3,6 percent of the total carbon dioxide emissions per year. The Fourth Assessment Report of the Inter-governmental Panel on Climate Change indicates that Africa will suffer the most from the impacts of climate change.

Climate experts say Africa is steadily warming, climate is changing and that there will be further changes in rainfall and temperatures. Africa is warmer by 0,5 degrees Celsius than it was a century ago. Climate experts say Africa is particularly vulnerable to climate change because of various factors such as widespread poverty, the unsustainable use of natural resources, over-dependence on rain-fed agriculture and weak institutional support structures.

Global surface temperatures have warmed by up to 0,8C since the turn of century and climate experts say human activities are largely responsible for altering the atmospheric chemistry, particularly CO2 emissions from fossil fuel combustion.

Global sea surface temperatures have risen while climate change statistics indicate that globally the sea level has risen by 10-25 cm in the last 100 years.


Climate change studies also show an increase in GHG concentrations from 1980s and extremes in climate over the same period. They say the main impact of climate change on the continent will be increased frequency of natural disasters, droughts, floods and other weather extremes that lead to loss of life, economic disruptions, social unrest and forced migration as well as major environmental problems.

Prolonged drought periods will cause stress on water resources and reduce food security due to diminished agricultural productivity, increase outbreaks of vector borne diseases and other health impacts. In addition, climate change poses a threat to forestry, water resources, biodiversity and other natural resources.

Globally, precipitation patterns have changed. Rainfall patterns in Zimbabwe also show similar trends with rainfall characteristics such as onset, dry spell, rainfall intensity, rainfall amounts showing signs of change.

Zimbabwe is experiencing an increase in the frequency of floods. Cyclone-induced flooding included cyclone Bonita 1996, Eline 2000, Japhet 2003 and another in 2007.

"With predictions that agricultural productivity in Zimbabwe could decrease by up to 30 percent because of increases in climatic extremes, climate change poses one of the most serious food security challenges of the 21st century in the country," Ms Chasi said.

"The high prevalence and intensity of poverty may amplify the negative impacts of climate change, particularly among rural and peri-urban populations, with unprecedented consequences on an already degraded environment."


are damning findings by experts in zimbabwe which shows that by 2030 zimbabwe will be like namibia which is being slowly engulfed by the Kalahari desert .

Climatic conditions collected at major weather stations in the country showed a worrying trend.

Water lodging in mutare ,Bulawayo runs dry

Its very paradoxical to say while in bulawayo people are struggling to get drinking water in  some parts of Manicaland water lodging is threating to destroy their houses .

In a snap survey conducted by this blog in manicaland , scores of people  expressed their shock and disbelief that while their life is threated by heavy downpours that are a common phenomenon in Manicaland during this rain season their counterparts in bulawayo are struggling to get few drops of water .

"Anytime from now we can experience a heavy downpour to us its no longer a mystery , but a thing we must live to experience everyday' ,said a Mutare resident identified as Tanyaradzwa Nyamutswa .

Since October last year Manicaland region has recieved a minimum of 257mm per month and Agritex officials have confirmed that the situation is dare and if it continues it can affect crop production and even the infrastructure of the residents .

"Crops are being destroyed and some fragile houses are being uprooted , this situation needs immediate attention from our government" , remarked  Manicaland Chief metereological officer ,Mr Artwell wikirefu.
However , some parts of matebeland such as Bulawayo people are going for days without water for domestic consumption .
"l  bath myself once a week ,its normal here in the once city of king s" ,said Believe Ndou , a Cowdry park old man .

Meanwhile ,the head of Engineering department in the bulawayo city council Engineer  Tamuka Gumbo has assured people that the city council in conjuction with the ministry of water are devising measures to curb the looming disaster .
"construction of zambezi water project is now at an advanced stage by May everything will be ok, " said Gumbo

Bulawayo water woes critical

Bulawayo water situation to worsen PDF Print E-mail

BULAWAYO residents are set for a harsh year with revelations that the water situation in the city is likely to worsen with the Bulawayo City Council (BCC) already searching for alternative sources of water outside the Government initiated solutions.
In an interview with Sunday News Bulawayo mayor, Councillor Thaba Moyo said there was no need to give residents false hope as the writing was on the wall that the water situation was not going to improve anytime soon.
Clr Moyo said it was highly likely that water rationing and shedding would remain a permanent feature in the city, as the supply dams were not receiving significant inflows.
“We have to look at this issue more broadly than we are currently doing, this is clearly a permanent crisis upon us and we must see that it is given the necessary focus because if we relax and wait for a solution to come to us, I tell you that we won’t be sincere as City Fathers.
“As you might know we recently held a water summit where we resolved that we have to look at other ways to solve this crisis outside all those that have been suggested by Government,” said Clr Moyo.
He said while the Government was still engrossed with completing the Mtshabezi-Umzingwane pipeline link project and the duplication of the Insiza pipeline, they would start developing their own solutions as the Government-initiated solutions were proving to be empty promises.
“Right now we have agreed that the only way we can solve this issue is by harnessing our underground water, rather than looking far to get this water, in the coming year I will personally spearhead the drilling of more boreholes at the Nyamandlovu acquifer and also at Rochester. The truth is that we have to face this problem on our own because it is not a Government official based in Harare who suffers but it’s us who have to endure this water shortage on a daily basis,” said the mayor.
Clr Moyo said they were tired of the excuses that were being made by the Minister of Water Resources, Management and Development Samuel Sipepa Nkomo over the Mtshabezi-Umzingwane project, thus their move to try to address the city’s water problems independently.
“One thing that we are faced with is a 96-hour water shedding period that is likely to increase if we don’t get any significant rain, further on we honestly don’t see us cutting short this exercise because our water situation is critical, therefore, whether we like it or not we are in a crisis and thus have to ensure we come up with some form of solution before residents start condemning us,” he said.
In the past, Minister Sipepa Nkomo has been attacked for failing the people of Matabeleland by dragging his feet and causing confusion in the implementation of water projects in the province. His ministry has been labelled the worst in Government.
At one point the minister even proposed that BCC should consider recycling water from Khami Dam for domestic use, a suggestion that was vigorously thrown out by leaders from the regio

Winter season dawns Zimbabwe

The chill atmosphere that characterises many mornings in zimbabwe is a  clear sign that winter season is slowly approaching zimbabwe .
In a snap survey conducted by this author ,thousands of people confirmed that the chill conditions in the mornings these days  are a clear sign that we are parting ways with the rain seasons despite the fact that in cities like bulawayo erratic rains were experienced .
"Its a thing that needs common sense , winter is approaching . You do not need to be a rocket scientist or be a degreed metereological officer'
