Several studies have shown the global increase in food demand by 2050 can be met by increasing yields on existing cropland, but HYPERLINK "http://www.pnas.org/content/early/2016/12/07/1610359113" a new study finds that countries in Africa south of the Sahara likely will be unable to meet growing cereal demand through yield increases alone.
An anticipated 2.5-fold population increase by 2050, combined with income growth, is expected to triple current cereal demand in the region and will require a multi-pronged approach to food security. The study, “ HYPERLINK "http://www.pnas.org/content/early/2016/12/07/1610359113" Can sub-Saharan Africa feed itself,” examined 10 countries in Africa south of the Sahara that jointly make up the majority of population and arable land in the region: Burkina Faso, Ghana, Mali, Niger, Nigeria, Ethiopia, Kenya, Tanzania, Uganda, and Zambia.
The researchers found that cereal yields would need to increase from 20% of their potential to 80% to maintain current levels of self-sufficiency. Even with this increase in yield more farmland would be needed to attain full self-sufficiency, which is in short supply in much of the region. Ensuring food security in the region will therefore still require increased trade and food imports.
“Self-sufficiency is not a goal in itself, as food security can be achieved through a variety of pathways,” said Keith Wiebe, senior research fellow at the International Food Policy Institute and a co-author of the report. “Boosting crop yields is essential and can go a long way to help meet future food demand; but these countries will also need to increase incomes in other sectors of the economy to ensure adequate food supply – be it from domestic production or imported from regions projected to produce a surplus.”
Cereal demand between 2010 and 2050 is expected to increase by 335% in the region, and over 500% in Niger and Zambia. Population growth accounts for three-fourths of these increases. According to the research, each country in the study except Ethiopia and Zambia have populations and demand growing faster than cereal yield increases.
Without significant growth in yields these countries may turn to expanding cropland to feed their growing populations, which would likely be accompanied by biodiversity loss and increased greenhouse gas emissions. If current yield growth rates continue into the future, an additional 97 million hectares
would be needed to achieve self-sufficiency. Seven of the 10 countries in the report, however, do not have enough land suitable for agriculture development to support such an expansion.
Noting these environmental concerns, the authors indicated increasing cropping intensity and irrigated production in regions that can support these activities are the more sustainable options. The authors recognized that a nation’s economic growth is often dependent first on economic growth in the agricultural sector, and emphasized the importance of public and private investment in agricultural research and development.
“These countries must innovate to increase crop yields because there simply isn’t enough land to continue farming as usual,” said Daniel Mason-D’Croz, scientist at the International Food Policy Research Institute and co-author of the study. “Technology will be key to feeding the growing populations of this region, and so will be policies that encourage sustainable economic development.”
The International Food Policy Research Institute (IFPRI) seeks sustainable solutions for ending hunger and poverty. IFPRI was established in 1975 to identify and analyze alternative national and international strategies and policies for meeting the food needs of the developing world, with particular emphasis on low-income countries and on the poorer groups in those countries.
Prices for cereals or staple foods in Botswana and other Southern African countries continue to rise at a slower pace, following trends in the global markets, according to the latest November 2022 Food Price Monitoring and Analysis by Food Agricultural Organization (FAO) of the United Nations.
Running a digital businessMTN Business Solutions Botswana, popularly known as MTN Business is an Internet Service Provider. We are a subsidiary of MTN Group Limited, a multinational telecommunications Group headquartered in South Africa, which operates in 19 markets across Africa and the Middle East.
More and more, clients are looking for ways to keep their staff productive in a dynamically changing business environment. Whether your people are working from home, the office or abroad, there is a growing recognition that digitising your operations can offer unprecedented commercial value in flexibility, productivity and growth. This new, digital reality means that it is more important than ever to stay agile – if there is anything that can slow a business down, it is being burdened by othatld technology.
Having made substantial investments in fibre technology, high-speed terrestrial and undersea networks and new frequency spectrum across the markets wherein it operates, MTN is perfectly positioned to respond to this shift in the market.
A few years ago, MTN also made the decision to build an IP capable radio network for its mobile services, giving its core network the ability to seamlessly integrate with enterprise IP networks. The mobile towers deliver services to enterprise clients absolutely anywhere it has a network, shortening the last mile and removing complexity and cost.
Now there is increasing demand from clients to connect their remote sites in all areas, including rural and semi- rural. MTN has assisted clients with overcoming this connectivity hurdle, enabling their staff to get the job done wherever they are.
For MTN, the focus has shifted from just being a core telecommunications services provider, towards also becoming a technology solutions provider. The service offering now also includes Unified Communications, Data Hosting and Cloud Solutions, Security-As-A-Service and Managed Network Services. The scope has changed to being client and industry specific, so the requirements and service portfolio vary from one client to the next. The expectation is that a company like MTN must respond to these challenges, helping clients to get business done better as they shift from old to new technologies.
As many businesses continue to grapple with a digitally dynamic world, they face new challenges that have to be solved. This environment will benefit those that are more digitally enabled and agile. It is a brave new world that will favour online over on-site, wireless over wired and fluid over formulaic. Businesses will seek out partners and suppliers that are every bit as flexible and forward-looking as they are.
Ultimately, clients need partners like MTN Business that will invest in infrastructure, deliver the services they require, have market credibility, are financially sound and have a long-term commitment to their market presence.
Botswana Institution Of Engineers (BIE), has last week hosted a gala dinner in which they appreciated engineers who worked tirelessly and with dedication for 10 years from 1983 to steer the BIE to its current status.
The event that was held at the Phakalane Golf Estate had brought together young, experienced and veteran engineers and was held under the theme “Vitalize the dignity and eminence of all professional engineers”.
Explaining the theme, the institution’s treasurer, Thanabalasingam Raveendran said that engineers were looked upon reverentially with respect as the educated but with time it seems to have deteriorated. He indicated that there is a need to change the narrative by all means.
“The BIE exists for the welfare and the betterment of us Botswana engineers, we need to recognize specialised units within our Institution. We Engineers strongly believe in Engineers make it happen” Raveendran said.
He indicated that under the theme they appeal to all engineers to energize, to attain quality of being worthy of honour and respect and to achieve recognized superiority amongst the Society.
Raveendran stated that engineers need to ensure their end product is of good quality satisfying the end users expectations and engineers must be honest in their work.
“Approximately 8000 engineers registered with Engineering Regulatory Board (ERB) are not members of the BIE, engineers need to make every effort to recruit them to BIE” he said.
He alluded that BIE being a society, it currently needs to upgrade itself at par with professional institutions elsewhere like the UK and USA.
He further stated that BIE has to have engineering units of specialised disciplines like Civil/Mechanical/electrical etc
“As President Masisi indicated in his inaugural speech, the young people, who make 60 percent of the population of this country, are the future leaders and therefore investing in them is building the bridge to the future” said Raveendran
Kandima indicated that BIE has a memorandum of Understanding with Engineers Registration Board (ERB), where BIE is a recognised provider of CPD training, mentorship programmes and more importantly IPD undertaking to upgrade the skills and know-how of our engineers.
“For us to achieve our mandate and make worthwhile changes to engineering in Botswana, we have to be totally focused and act with intent” said Kandima.
Furthermore, Stephen Williams, past president of the BIE from 1986-1988 told the engineers that the BIE provides a fertile environment where they can meet, share ideas and grow professionally.
“The BIE is also a nesting place for graduate engineers to learn from their peers and seniors, it also cater for engineering technicians and technologists and so nobody in the technology field is left out” he said.
He further indicated that Botswana Government provides a conductive environment for growth of engineering professionals.
“It must be stated that the Botswana Government recognises the existence of BIE and it can further be stated that the government enables ERB to carry out its mandate as a regulator of engineering professionals” said Williams
He plead with engineering companies to recognize and support BIE as it is the only source of engineering personnel’s for various Industries .
Furthermore, when giving his farewell speech, Michael Pinard , a past president of the institution said how they are viewed as engineers by the general public might be due to some lack of appreciation as to exactly what role they play in the development of the country.
“The BIE slogan is aptly coined-Engineers make it happen, in other words, what man dreams engineers create” Said Pinard.
