GOVERNMENT HIKES BUYING PRICES FOR MAIZE
November 11, 2019 / Tawonga Nyirenda Mayuni

The Malawi Government has hiked the buying price of maize at all Agricultural Development and Marketing Corporation (Admarc) rural markets and depots from K150 to K250 per kilogramme. Secretary for the Ministry of Agriculture, Irrigation and Water Development Grey Nyandule-Phiri says in a statement that the move is aimed attaining national food security as it will attract more farmers stocking maize to sell to the parastatal. Nyandule-Phiri says the government has made the decision to hike the buying price for the staple food crop after noticing that there was a slow pace of inflows to Admarc implying that the previous buying price was not attractive to farmers. “Government has, therefore, revised the buying price to K250 per kilogram for all maize delivered to Admarc depots and K230 per kilogram for all maize delivered to Admarc rural markets,” he said. The Ministry has since given local farmers and traders two weeks to sell their maize to any Admarc markets and depots, and says it will seek importation of maize from suppliers identified outside the country if it fails to secure enough maize by November 25, 2019. The Malawi Government commissioned the Strategic Grain Reserve with the aim of stocking maize. Nyandule-Phiri says the arrangement has assisted in ensuring that the country has maize stocks in adequate quantities acquired through procurement by Admarc and National Food Reserve Agency.

Energy
EU lauds benefits of Mozambique-Malawi interconnector
November 08, 2019 / Wahard Betha

The European Union (EU) Mission in Malawi has described the Mozambique-Malawi 400kV interconnector project as game-changer, saying it will link up Malawi’s energy grid to the regional electricity market of the Southern Africa Power Pool (SAPP) and facilitate trading as well as balancing of electricity among countries within the region.


EU Ambassador Sandra Paesan made the observation in a statement in which she hailed the ‘great things’ that happens when the EU and Malawi put their energy into joint projects.


Paesan said in partnership with KfW (the German Development Bank), the EU is supporting the Mozambique-Malawi 400kV interconnector project alongside other regional infrastructure initiatives aimed at boosting regional trade and economic growth.


Other initiatives that EU supports include the North-South M1 corridor in partnership with the European Investment Bank and the Nacala road corridor in partnership with African Development Bank.


She said currently lack of access to reliable power is preventing Malawi from realizing its full economic growth and development potential as businesses and people are affected by regular power cuts and high costs of power through diesel generators.


The ambassador noted that energy being one of the main drivers of inclusive and sustainable growth and jobs, Malawi needs reliable power supply if it were to achieve meaningful economic development.


In this vein, she explained that the interconnector project will provide Malawi’s business sector with more secure supply, which in turn will create an environment where business development can accelerate.
She also said having attained dependable power supply, there will be a multiply effect as growth in agricultural sector will benefit from new value chains that depend on a secure and affordable source of energy.


“A secure supply will further led to improved productivity as businesses will be in a position to operate uninterrupted while optimizing investments,” she said.


Paesan noted that Malawi’s energy infrastructure needs are quite substantial hence the need to attract private investment into the energy sector, particularly in renewable energy, to complement efforts from development partners.


She welcomed the initiative by the Malawi Government to procure 70MW of solar energy, saying it is in tandem with Africa-Europe Alliance and European External Investment Plan.


“Renewable Energy is the future and Malawi should fast-track the process of this initiative which started two years ago, so that the country realizes the benefits of such power investments,” she said.
The diplomat said European companies are ahead on the market when it comes to renewable energy investment and will be available to help Malawi in this respect.


“It is critical to continue our joint efforts to strengthen Malawi regional connectivity and infrastructure in view of supporting inclusive growth and development for all Malawians” said Paesen.
The EU recently organized a meeting with private firms in Blantyre, which discussed investment bottlenecks, including the prevailing energy woes.

Construction of Mzuzu Youth Centre on the cards
November 07, 2019 / Wahard Betha

The Malawi Government is seeking to prequalify contractors for the construction of Mzuzu Youth Center and ancillary facilities at Katoto in Mzuzu city.

The Ministry of Youth, Sports and Culture says in a statement that the tender is open to local contractors currently registered in the unlimited category (building) of the National Construction Industry Council of Malawi (NCIC) and any interested international contractors that are registered in the equivalent category in their respective countries.

It says the pre-qualification questionnaire documents can be obtained at the ministry’s office at Capital Hill in Lilongwe or on its website (www.ppda.mw) from November 6 during working hours.

“The pre-qualification questionnaire document contains methods, criteria and factors that the Government of Malawi, referred to as procuring entity or employer shall use to evaluate and determine whether a contractor has the required qualification to effectively, efficiently, technically, economically and sustainably executive the said works in order for the employer to achieve the desired business objectives,” says the Ministry.

The deadline for submission of pre-qualification documents is December 9 at 15:00 hours local time.

“Interested contractors and/ or their representatives and members of the general public, may attend the opening of the bids at 15:00 hours local time on Monday November 9 2019 in the conference room of Ministry of Youth, Sports and Culture-Capital Hill in Lilongwe,” it says.

The Ministry is advising bidders to ensure that the documents are submitted in accordance with ‘The pre-qualification requirements’ in the documents, as non-compliance will lead to disqualification and rejection of the contractor.

The bids shall be valid for 30 days after bid opening.

CFTC PROBES BUS OPERATORS OVER POOR CUSTOMER CARE
November 06, 2019 / Bester Kayaye

The Competition and Fair Trading Commission(CFTC) says it is investigating cross-border bus operators; InterCape, Taqwa and Jobella Star bus company over allegations that they mistreat their customers.

CFTC says the investigations have been instituted following complaints the Commission has received from passengers and baggage transportation customers for the said cross-border bus operators.

The Fair Trading regulator says, among other concerns raised by the customers, the companies have been denying liability of customers’ goods lost or damaged on transit.

The customers have also reported the companies to the Commission against improper handling of passengers particularly not attending to their physical or health situations during the trips, which is contrary to section 43 of the Competition and Fair Trading Act.

Acting Executive Director for CFTC  Martha Kaukonde  says in an interview that the Commission is handling the cases in accordance with the Competition and Fair Trading Act (CFTA) and the Consumer Protection Act (CPA) which, among other things, prohibit suppliers of goods and services from engaging in unconscionable conduct.

She says: “We have received complaints from customers that their goods are pushed or piled without proper care, which results in the luggage being lost while fragile items get smashed, and the operators have demonstrated unwillingness to provide satisfactory assistance to the affected travelers when they have presented their complaints to their respective offices.”

“The conduct by the said bus companies appear to amount to a violation of Section 43 (1) (g) of the CFTA Act which states that “a person shall not, in relation to a consumer, engage in unconscionable conduct in the trade of goods and services.”

Kaukonde says “so far the commission has followed up on affected customers and former employees in a quest to unearth relevant evidence to present before the board of the Commission that will determine penalties for the companies if found guilty.

Meanwhile, CFTC is urging victims of such malpractices to present their concerns to the Commission in a bid to improve the customer service delivery of the buses.

Govt. banks on farmer cooperatives to develop agribusiness
October 22, 2019 / Gloria Mbwana

There is a need for the country’s small-scale farmers to form cooperatives if they are to graduate from subsistence to commercial farming.

Registrar of Cooperatives in the Ministry of Industry, Trade and Tourism Wiskes Nkombezi said this atthe official launch of the Cooperative Development Activity 4 (CD4) project which is being implemented by US premier agribusiness company, Land O’Lakes, with funding from USAID to the tune of $1.7 million.

Nkombezi said: “The Government of Malawi is encouraging farmers to come together, through cooperatives and pursue farming as a business; the CD4 comes in as a part player, joining the Government of Malawi and other development partners to further this agenda”.

He expressed gratitude towards development partners who are taking part in strengthening farmer based organizations saying it would be difficult for the government to succeed in the project without their support.

“Collaboration is very important. Therefore, I take this opportunity to request all partners present today to synergize your efforts, as we all continue to contribute to the development and growth of the Cooperative Movement in Malawi. We will achieve the goal of sustainable economic growth and poverty reduction if we continue working together”, Nkombezi said.

The CD4 aims to improve the cooperative enabling environment by strengthening apex organizations and by promoting a Cooperative Learning Platform, enhance cooperative business performance through tailored technical assistance and to advance development communities support for cooperatives through supporting research in cooperatives and disseminate findings through both local and global channels.

Nkombezisaid the project is important to strengthen cooperatives as some collapse due tolack of knowledge on how to run them as business enterprises.

“Cooperatives need technical capacity strengthening to support their sustainability and growth. If cooperatives are strengthened in aspects of business operations, they are empowered to make sound business decisions which in turn enhances their growth,” Nkombezi said.

In his remarks, USAID Office Director Cullen Hughes said CD4 has come in at an opportune time when Malawi government and development partners are strategizing on the implementation of the National Agricultural Policy (NAP).

NAP emphasizes on developmentof farmer organizations as a key intervention for driving Malawi’s agricultural development.

“In response to the need for strong farmer organizations in the operationalization of the NAP, the Department of Agricultural Extension Services has developed a strategy for farmer organization development to which the program being launched today is closely aligned,” he said.

Agriculture remains the driving force of Malawi’s economy contributing approximately one third of the country’s Gross Domestic Product (GDP) and nearly 80%of export revenue.

Govt. secures funds for Mangochi-Chiponde road works
October 16, 2019 / Wahard Betha

The Malawi Government has secured funds from the African Development Bank (AfDB) to kick-start the 53km Mangochi-Chiponde (M3) road rehabilitation project.

The Roads Authority (RA) is, meanwhile, inviting consulting firms to undertake engineering studies including a feasibility study and detailed engineering designfor the project.

Procurement Specialist for RAMoses Malinda says in a press release that the consultancy assignment is expected to be executed in 46 weeks.

“Interested consultants must provide information indicating that they are qualified to perform the services (brochures, description of similar assignments, experience in similar conditions, availability of appropriate skills among staff etc.),” Malinda explains.

He says consultants can also form joint-ventures to enhance their chances.

Malinda says RA will apply shortlisting and selection procedures stipulated in the AfDB’s ‘Rules and Procedures for the Use of Consultants’ of 2016.

He says: “Interested consultants may obtain further information at our website or physically contact us during office hours from 08:00to 16:00hrs local time from October 8th to 23rd, 2019 with clear indication of the bid title.”

The Mangochi-Chiponde road project is under the Multinational Nacala Road Corridor Development Project Phase V.

RA is a quasi-government body which was established by an Act of Parliament in year 2006 with a mandate to ensure that public roads are constructed, maintained and rehabilitated at all times.

Trade Ministry lauds achievements of Export Strategy
October 16, 2019 / Wahard Betha

The Ministry of Industry, Trade and Tourism has lauded achievements in the implementation ofthe first National Export Strategy (NES I) which ran from2013 to 2018.

Principal Secretary in the Ministry Ken Ndala said during a consultative workshop in Lilongwe to brainstorm on the design of the National Export Strategy IIthat achievements of the initial phase include development of the Trade, Industrial and Small and Medium Enterprises Policies; and Control of Goods Act.

The achievements also include operationalization of the Buy Malawi Strategy; development of the National Trade Facilitation Action Plan; Construction of Standardization, Quality Assurance, Accreditation and Metrology (SQAM) infrastructure at Malawi Bureau of Standards; setting up of One Stop Border Posts; and establishment of One Stop Service Centre at Malawi Investment and Trade Centre.

Ndala said fruits of the NES I also include Simplified Trade Regimes, establishment of Online Business Registration System, establishment of the Collateral Registry, Development of the Financial Literacy Strategy, Development of the Warehouse Receipt Bill, The Credit Reference Bureau Act,and The Personal Property Securities Act.

“The NES I also yielded the Establishment of Online Investment; Development of Labor Market Information System (LMIS); Development of the National Labor and Employment Policy; Establishment of Malawi Trade Portal; and Linking smallholder irrigation schemes to seed companies,” he said.

Ndala also said the strategy resulted in the introduction of an online Oil Seed Extension Coordination Platform and Decentralization of the issuance of crop buying licenses to Agricultural Development Divisions (ADDs) across the country.

He saidthese outstanding results were achieved through Technical Working Groupswhich were set under the Trade, Industry, and PrivateSector Development Sector Wide Approachasthe implementation platform of the NES I.

Ndala said such benefits from the NES I are an inspiration to launch the NES IIadding that the first phase has provided legal frameworks for the implementation of NES II.

He said it is imperative to undertake NES II tofinalize the key investments that were supposed to be undertaken in the sector under NES I as well as deal with emerging issues that will be identified in this successor strategy.

Despite the notable achievements, the NES I still did not fully address the policies that the Ministry set in the plan.

Ndala said the under performance of the NES I was due to the deficient resource mobilization with heavy dependence on development partners and donor agencies and also low level of investment in productive sectors in terms of local investment in manufacturing projects with high value addition.

“The NES was overdesigned and too ambitious to be realized within a five-year period, given the prevailing conditions; It reflected more of an Industrial Policy rather than an Export Policy as very limited actions for effective export promotion, facilitation, export development, aftercare, and policy advocacy were planned,” he said.

Ndalaalso said week and ineffective collaborative framework between Ministries and Agencies affected competitiveness of local products and services on the international markets following the higher costs of doing business in Malawi as compared to other competing countries. 

Commenting on the challenges faced, Director of Planning in the Ministry Francis Zhuwaosaid the obstacles arose due to unpredictable financing leading to no drastic growth in exports as expected that necessitated the review and development of the successor strategy.

“With support from the Commonwealth Secretariat, we have therefore gone into the development of a successor strategy. It is my sincere hope that we will give this process the same support that we gave during the design of the NES I,” Zhuwao said.

He expressedgratitude to the Commonwealth and all development Partners in the Trade, Industry and Private Sector Development sector for technical and financial support.

In her remarks, Commonwealth Trade Adviser Yinka Bandele said the body saw it right to fulfil their duty of supporting developing countries on economic issues.

Bandele said: “The Commonwealth is very committed to supporting member countries’ efforts to achieve the Sustainable Development Goals, including through trade. We look forward to working with the Government of Malawi on a new strategy that will overcome key hurdles to growth and help transform the economy.”

She further urged the government to draw lessons from the previous NES in strategizing the new plan.

Bandele also said Malawi needs to work on economic diversification to do away with over-dependence on agricultural produce.

Malawi, whose main export commodities include tobacco and tea,is facing a significant trade deficit as it is importing about twice the value of goods it exports.

The Ministry is, therefore, working on finding solutions to issues affecting trade competitiveness, and identifying priority sectors for export development and lead markets for increased trade.

The Ministry is designing NES II and Action Plan for 2020-2025, a process which will be finalized later this year.

Lafarge storms market with Instacrete ready mix concrete
October 14, 2019 / Wahard Betha

Cement manufacturing giant LafargeHolcim Malawi has taken the market by storm with the launch of Instacrete Ready Mix Concrete, which is the first commercial ready mix concrete to be introduced on the Malawi market.

Lafarge CEO Albert Sigei said at the launching ceremony of the Ready Mix Concrete at the Company’s Central Region offices in Kanengo, Lilongwe, that the new product will simplify the building process for contractors making it faster, better and safer as compared to the man mixing process.

Sigei said; “Building solutions around the world have been evolving; and the same needs to happen in Malawi. As a country with one of the highest urbanization rates in the world, it is expected that the demand for infrastructure development will be high.”

“Building solutions that provide faster and higher quality materials for the development of that infrastructure are, therefore, critical at the current stage of our country’s development.”

Instacrete Ready Mix Concrete will be produced by InstaCrete Limited, a subsidiary of Lafarge.

Lafarge also launched a concrete laboratory that will support InstaCrete through provision of technical services by ensuring that the concrete mix designs are innovative and tailored for different building projects.

“This laboratory has the capability to develop concrete mix designs, test aggregates and provide technical expertise for major concrete structural work. The laboratory is open to all customers that may wish to use these services,” he said.

Lafarge’s Head of Marketing and New Solutions ChikondiNg’ombe, urged building contractors to start using Instacrete Ready Mix Concrete saying it is far much better than the man mix process which on some occasions has resulted in the collapse of the structures due to poor mixing.

“It is difficult to control quality using the man mixing process as some mixer’s overdose on some materials,” she said.

Lafarge has only introduced the new product in Central Region but Ng’ombe said the Company has planned to introduce the Concrete in Northern and Southern Regions since there is rising demand for the product which shows that the market is ready for it.

“We have a readily available market for the product and we have already started supplying to some major Lilongwe construction works including Area 18 interchange,” said Ng’ombe.

Formerly Portland Cement Company, LafargeHolcim Malawi has been a leading building solutions provider in Malawi for over 60 years providing innovative building solutions serving masons, builders, architects and engineers.

Lafarge’s cement brands include Supaset (CEMII 42.5R), Duracrete (CEMII 32.5N), Kumanga (MC 22.5X), and Khoma (MC5).

The Company also produces SupaLime (hydrated lime) and, according to Ng’ombe, other innovative products are in the pipeline.

An Overview of Mine Tailings and Waste Rock from Mineral Processing and Mining respectively
October 14, 2019 / Ignatius Kamwanje

There are two to three types of wastes that are generated by mining activities. These are Waste Rock that is stored, secured in waste dumps and can be used as fill material, road construction and other infrastructure, Processed Rock commonly known as Tailings (containing chemicals) that is stored in construction facilities and where possible, these chemical solutions together with pulverised rock are    recycled in order to be used before being pumped into the storage facilities and also Mine Water which will not be discussed in this article.

1.            Mine Tailings

Mine tailings are finely grounded residual materials that remain after removing an ore of economic value from a process plant. Tailings is usually a by-product of mineral recovery processing and is mostly in form of liquid slurry made up of very fine particles from crushed, grounded, and processed with water and possess no any financial gain at the point of disposal. Tailings are processed from the mill and are diverted to storage built structures that are commonly referred to as Tailings Storage Facilities (TSF).

These storage facilities are in form of dams, embankments and other types of surface impoundments. It must also be noted that the material that goes to tailings facility might also contain significant amount of metal due to very poor recovery and that at some stage some mining companies may wish to reprocess to recover it, although this is not a common practice in most mine ore processing.

2.            Tailings Management

Tailings are usually stored using the most effective way inorder to meet specific regulations and standards. It must be noted that tailings structures are built in a differing fashion to suit a particular environment and specific mineral processing method. The ground conditions and   the environment are the most crucial parameters that control the storage of tailings hence geotechnical analysis at feasibility study is of very fundamental importance.In cases where    tailings do not contain substances that are harmful or toxic, water is sometimes diverted inorder to retain the physical stability of the facility by way of covering with soil, reshaping and planting vegetation cover and subsequently put into land use in the long term.

Tailings management is the primary responsibility of a mining company both during and after mining operations. Subject to advanced statutes, tailings management needs to be very cost effective throughout the mine life even beyond post closure period. Management of tailings include enhancement of mine workers on safety and health and also the nearby surrounding communities, developing new approaches for environmental protection, devising new ways of assisting the communities etc.

3.            Tailings Dam Failures

Tailings dam failures are caused by numerous factors among others the most occurred from past experience include:

(a) Unusual rainfall

✓ Too much rainfall leading to oversaturation thereby yielding rainwater that can overflow carrying with it the tailings away from the dam onto the downslopes.

(b) Foundations and Structure

✓This can be caused by design errors, structural inadequacies and failed decantation. Also foundations with insufficient investigations that fail to guide enough support to the weight of the dams.

(c) Seismic liquefaction due to earth tremors/earthquakes

✓ Structure is destroyed by continuous shaking of the ground motion and since dams are designed to withstand such vibrations, there is instability created if the movement is larger than anticipated.

(d) Subsidence of the mine

✓ Sometimes the dam is built above an underground mine; the underground mine may collapse and the mine workings can absorb water and overflow when the subsidence is filled to capacity.

(e) Seepage and Erosion

✓ Due to rainfall, there may be erosion of the face of the dam that may be difficult to maintain or repair. Besides, erosion of dam/embankment materials due to seepage or underground drainage to areas that were designated as dry, may cause dam failure.

In all these causes of dam failures, the potential impacts is on biodiversity and associated ecosystems. These, in the long run cost companies massive financial compensations and also reconstructions projects to stabilize the dam structures.

4.            Examples of Tailings Dam failures for the past 5 years

Worldwide, there have been numerous catastrophic dam failures over the years. The most recently noted is the deadly dam burst due to mudslide at the Corrego do Feijao mine in Brazil operated by iron ore mining giant, Vale and happened in January, 2019. It is alleged that 13 Vale employees and a German Auditor TUV SUD are involved in a tussles where Brazilian Authorities are accusing them of fraud by presenting fake documentation backing the dams’ stability where about 250 people were nearly killed and mine waste tailings (about11.7 cubic metres) spilt all over to close by mining towns and the countryside below. It is also alleged that homicide and environmental damage case could not be ruled out. In another development, Vale has set aside $107 million for compensation and also projects to spend $471 million on dam stabilization projects by 2023.

On the same note, there have been tailings dam failures in Brazil like the Samarco iron ore dam failure mined by a giant BHP Billiton that killed 19 people, displacing 700 people and the Doce river valley was highly devastated and contaminated in 2015. This was considered the worst environmental disaster. Following this catastrophe, a lawsuit was served at Liverpool high court by a law firm SPG and over 200,000 Brazilians claimed damages of about $5 billion which was the largest in United Kingdom’s history.

In Canada, the Mount Polley gold and copper Mine run by Imperial Metals Corp collapsed in (2014) where toxic water from the mine tailings spilt over the Lake Polley. About 24 million cubic metres of tailings waste and sludge was deposited into nearby creeks causing an environmental concern and charges related to Fisheries Act were to be laid down under the Federal Law. These are but only a few examples of dam tailings failures and if these are not properly managed, they bring huge financial costs and implications to the mining company and great care should be exercised when operating these structures though some of the causes are natural in nature.

5.            Waste Rock

Waste rock is unwanted rock material that has been removed/excavated from the pit after mining and does not have a metal content of economic value. Waste rock is also a high volume of material that also may originate from chemical processing of metalliferous and non-metalliferous minerals by either opencast, adit and underground mining .The waste rock may however contain metal that is too way far below the cut off value. Usually the volume of mine waste is larger than the metallic ore and this mostly depends on the stripping ratio (ratio of waste to ore).  For example, a stripping ratio of 4:1 means that 4 tonnes of waste rock needs to be mined inorder to mine 1 tonne of ore. Generally, in open pit mines, the stripping ratio is on a higher side than in an underground mine for the obvious reasons and the waste rock is often stored close to the mine to minimize transports. The waste rock is deposited in stockpiles.

The amount of waste rock that needs to be removed from the pit depends on the rock geometry, location of the ore body along with the mining method used, the composition and stability of the rocks as well.

6.            Environmental impacts of waste rock

Mined waste covers a considerable area as such, issues of groundwater contamination are very common. In most mines, mining waste rock is also used as an earth road/work fill material and this can be a long term potential water contaminant.

However, when the rocks contain certain minerals in enough quantity combined with poor management of the waste, it can become a large risk to the environment and health of local communities. In some cases, the mine uses certain chemicals such as cyanide in the processing stage. These chemicals often account for a small volume of the total waste, but can pose a large risk due to their high toxicity.

In areas where coal mining takes place, the rock waste contains sulphurous compounds that are susceptible to Acid Rock Drainage formations. This causes both ground and surface water contaminations. Sulphide minerals are easily weathered when in contact with oxygen. When sulphide minerals break down, they can produce acid water. The acid water further speeds up the weathering of the minerals, called chemical weathering. The result is an acid water with high metal content. This is now referred to as acid rock drainage (ARD) or acid mine drainage (AMD).In terms of groundwater, the acid leachate affects water quality due to high concentrations of some elements in the saturated zones

7.            Managing Waste Rock

✓            Included in the Environmental Management Plan.

✓            Environmental audit and inspections are vital

✓            Following relevant legislative guidelines on environment

✓            Consider future landform uses e.g. during rehabilitation and post closure period.

✓            Development of infrastructure e.g mine roads, landfills, buildings.

✓            Erosion maintenance

Another Management is to adopt a risk-based management approach. The risk management process is based on Risk Assessments. The risk assessment identifies risk pathways (unwanted event and the associated environmental receptor/factor), which may cause material impact to key environmental factors. It also identifies the level of uncertainty associated with a risk pathway, which can be low, moderate or high depending on the degree of uncertainty.
