Name and Capacity Signature Date D. Parry (Director) 30th October 2008 Final EIS Volume 1: Morupule Colliery Expansion Project December 2008 EXECUTIVE SUMMARY Introduction This Environmental Impact Statement (EIS) presents the results of the Environmental Impact Assessment (EIA) for the proposed Morupule Colliery Expansion Project at the Morupule Colliery in Palapye. The EIS will be submitted to the Department of Environmental Affairs (DEA) the EIA authority, for review and approval. The study was initiated by Morupule Colliery Limited (MCL), the owner of the colliery, and was conducted by Ecosurv (Pty) Ltd. The key objectives of the EIA are to: • examine the environmental and social character of the area that is likely to be affected by the project or development; • identify and evaluate the direct and indirect impacts resulting from the development; • identify and describe measures that will mitigate the identified negative impacts and enhance the positive ones; • develop an Environmental Management Plan (EMP) and monitoring and auditing requirements; and • identify costs relating to closure of the colliery and the new infrastructure. Project Background MCL, a subsidiary of Debswana Diamond Company (Pty) Ltd has been operating a coal mine since 1973 and is currently producing approximately 1 million tonnes of coal per annum. The coalfield within the mining lease area is immense and contains good quality coal, with the estimated overall coal presence exceeding 5 billion tonnes. The Botswana Power Corporation (BPC), which operates a coal-fired power station nearby, has been the main consumer of the MCL coal. The colliery now proposes to expand its coal production from 1 million tonnes per annum to 4 million tonnes per annum in phase one and 12 Mtpa in phase two. The purpose of this expansion is to: • cater for an increase in power generating capacity at the BPC coal-fired power station site at Morupule. The power increase is expected to be 600 megawatts (MW) for Phase 1 and 600 MW for Phase 2, together with the current 132 MW of generating capacity. • produce beneficiated coal that has been processed through washing plants, for the local coal market and for export. • produce unbeneficiated coal of power station grade coal for supply to existing and new customers. The colliery has been given the authority by the BPC board to proceed with the planning and preparations aimed at ensuring adequate supply of coal to generate 600 MW for the Phase 1 expansion of the power station and the current 132 MW. Confirmation from BPC for the second phase is still pending. Proposed Activities Activities planned for the proposed expansion project (described in detailed in Section 3) include: Prepared by Ecosurv i Final EIS Volume 1: Morupule Colliery Expansion Project December 2008 • Phase 1: Four million tonnes per annum (Mtpa) mining from existing shaft, replacement of the surface screening and crushing facilities at the existing location, and construction of new workshops and offices and 20 housing units at Morupule Village; and • Phase 2: Twelve Mtpa mining from a new shaft some 4.5 km to the North of the existing shaft, and replacement of the coal wash plant. The pre-feasibility study for Phase 1 has been completed, while the study for Phase 2 is on- going. Construction of Phase 1 and Phase 2 will commence in 2011 and 2012 respectively and will each take three years. The operational life of each phase is twenty years. Existing environmental certification and archaeological studies are: • a situation analysis, EMP and closure plan have been prepared for the current mine shaft and its associated operations. No further EIA activity is envisaged for the existing operation. An archaeological impact assessment has been approved and salvage archaeology completed for the initial mine lease area and the first extension (to cover the surface area above the current mining area); • separate EIAs have been carried out for the proposed pipeline connection to the North- South Carrier (NSC) and for the existing coal wash plant. These have been approved by DEA. The colliery has applied for and received an extension to the lease area which covers the coal deposits as far as Serowe. The geographic scope of this EIA and AIA activity will be the surface area above the proposed expansion of coal abstraction activities. Within the proposed expansion area, there will be sections affected by clearing and excavation, access routes and utilities. The rest of the area will remain unchanged. Compensation and Resettlement A number of households reside within the colliery’s mining lease area. The colliery is planning to compensate and request all people who live within the 20-year mining lease area to move in the long-term. Compensation is required as the Land Board cannot give MCL the surface rights if the previous owners have not been compensated. This process is ongoing. Location The Morupule Colliery is located in the Central District of Botswana approximately 300 km north of the capital city, Gaborone, and some twelve kilometres north-west of Palapye towards Serowe. Approach and Methodology The process of assessing the impacts of the project encompasses the following: impact identification, impact prediction of their nature, magnitude, extent and duration, identification of mitigation measures that could be implemented to reduce the severity or significance of the impacts of the activity and evaluation of the significance of the impacts after mitigation measures have been implemented i.e. the significance of the residual impacts. The main areas of impacts were identified during the scoping phase through site visits, consultations and literature review. During the EIA study the impact were further investigated through specialists’ studies. The significance of the impact was determined as follows: Significance = Consequence (Extent x Intensity x Duration) x Probability. The result of the assessment of the significance of the residual impacts (Low, Medium, High) is linked to decision-making by authorities in the following manner: Prepared by Ecosurv ii Final EIS Volume 1: Morupule Colliery Expansion Project December 2008 • Low – will not have an influence on the decision to proceed with the proposed project, provided that recommended mitigation measures to mitigate impacts are implemented; • Medium – should not influence the decision to proceed with the proposed project, provided that recommended measures to mitigate impacts are implemented; and • High – would strongly influence the decision to proceed with the proposed project. Environmental Setting The project area experiences average annual temperatures between 30 °C and 14 °C. Mean annual precipitation is 371 mm with the majority of rainfall received between November and March. Potential evapotranspiration is in the order of 900 – 1,200 mm/year (WSB, 2007), which is two to three times the average annual rainfall. The dominant winds are north easterly with an average wind speed of 3 m/s. Air Quality Air quality around the colliery is affected by dust from coal screening, stockpiling and loading. The air quality is also influenced by emissions from the neighbouring Morupule Power Station in the form of ash, sulphur dioxide (SO2) and other particles. The results of the coal dust monitoring from samples taken above surface exceed the World Bank Group limits for ambient air quality. Monitoring of methane has shown zero gas content. The output may increase as the depth of the seam increases. Noise Noise levels in Palapye Village are high and are typical of an urban complex. The existing noise climate alongside the main roads in Palapye is degraded with regard to acceptable urban residential living standards (SANS 10103 noise impact criteria). In general the daytime conditions are acceptable (SANS 10103). The impact of the Morupule colliery on noise sensitive sites in the surrounding area is relatively minor. Noise levels from the colliery exceed 35 decibel adjusted (dBA), the maximum allowable night-time level for rural residential use, for up to a distance of about 2,600 m from the facility. Seven homesteads lie within this area of influence. The colliery village lies just outside this zone and is thus not impacted by the colliery noise. Topography The area is in general flat with the main landscape variation being that of the Tswapong hills which lie roughly 12 km south-east of the existing mining site. A number of small outcrops exist within the lease to the north. The Colliery village is situated between two of these outcrops. The Kalahari escarpment lies to the west of the lease area. The lease area is drained eastwards by the Morupule and the Lotsane rivers. Soils Soils in the area consist of an Aeolian layer of sand of between 2 and 9 m deep, averaging around 5.5 m, which overlays a band of ferrocrete/calcrete.

Samuel Mosweu1* and Moagi Letshwenyo2 1Department of Geography and Environmental Science, University of Fort Hare, Alice, South Africa. 2Department of Biological Science, University of Botswana, Gaborone, Botswana. Accepted 6 November, 2013 The aim of this research was to assess the suitability of roadside grass for use as livestock feed to combat lack of forage resources in Botswana. Fifty grass samples were collected along the roadside in the A1 Highway corridor running between the Ramatlabama and Ramokgwebana border gates (629 Km), and analysed for Ni, Cu, Pb, Zn and Cd. The maximum content levels detected in grass samples for Ni, Cu, Pb, Zn and Cd were 0.432, 0.187, 0.180, 0.154 and 0.03 mg/kg respectively. Assessment of the results against international maximum allowable limits of undesirable substances in animal feed showed that the content levels of heavy metal contaminants in grass resources found along the roadsides in the A1 Highway corridor in Botswana were far below maximum allowable limits. Therefore, this study supported the use of roadside grass for production of forage to combat scarcity of livestock feed in the country. However, the study recommended the establishment of an environmental management and monitoring approach to facilitate continued monitoring of the quality of forage produced from roadside grass and ensure protection of human and animal health.

Gwatiwa Program in International Cooperation, Graduate School of International Studies, Yonsei University, South Korea. E-mail: [email protected]. Accepted 24 April, 2019 Botswana is considered one of Africa’s credible democracies. Its economic performance and good governance over the years distinguished its statehood from its African counterparts. The stable political landscape backdating to independence also made it a regional security exception. However, the security landscape has changed over the last three years. Using a historical procedure, the article illustrates how the changing political landscape resulted in the creation of a securitized state controlled by intelligence agencies. It also employs a survey procedure—using interviews and other qualitative sources—to illustrate how incidents of incidents of intellectual repression, communication surveillance, extra judicial killings and politicized covert operations have changed the country. The article interrogates the magnitude of security threats as well as the competence of the intelligence security outfits. Having proven the existence of common denominators of state terrorism in Botswana, which point to emerging state terrorism, the study proceeds to make recommendations for structural and operational reform. Key words: Botswana, Directorate of Intelligence and Security (DIS), state-terrorism, extrajudicial killings, surveillance.

  • THE FINANCING of CITY SERVICES in SOUTHERN AFRICA Preface
    THE FINANCING OF CITY SERVICES IN SOUTHERN AFRICA Preface A follow-up of a previous report published by the SACN in 2008, this publication examines the challenge of financing infrastructure in the Southern African region. Infrastructure investment in Southern Africa and the rest of the continent is of particular significance, as it is increasingly recognised as pivotal to the goals of economic growth and tackling poverty. The geographical spread of the project included ten city municipalities across the countries of Botswana, Mozambique, Mauritius, Tanzania, Namibia, Zambia and Malawi. The research involved city visits, where interviews with key individuals were conducted, and an in-depth analysis of their financial statements, as well as plans and policies relating to infrastructure and services. This project had a number of key activities. One was to understand the financial health of these municipalities, which was linked to providing credit assessments for all the municipalities visited, allowing them to rate their ability to borrow in order to meet some of their infrastructure needs. This publication, with its detailed financial profiles and analysis of major issues relating to city finances, is a primary product of this aspect of the project. Another aspect of this project was to conduct financial capacity building in a selected number of these municipalities, providing senior managers with focused training on enhancing city creditworthiness. The project culminated in a knowledge dissemination event in Johannesburg South Africa on 25 May 2011, at which the publication was launched, broad findings of the project were discussed and city officials were invited to share financial management lessons learnt within their organisations.

Mayunga1, Thabo Rabamasoka2 Botswana International University of Science and Technology, Private Bag, 19, Palapye, Botswana mayungas[at]biust.ac.bw1, thabo.rabasiako[at]studentmail.biust.ac.bw2 Abstract: Civil engineering structures such as dams, bridges, tunnels, high rise buildings etc. are susceptible for deterioration over a period of time. Bridges in particular deteriorate after being constructed due to loading conditions, environmental changes, earth movement, material used during construction, age and widespread corrosion of steel. Bridge deformation monitoring is most important as it determines quantitative data, assesses the state of the structure and detects unsafe conditions at early stages and proposes necessary safety measures before can threaten the safety of vehicles, goods and human. Despite government’s efforts to construct roads and highways in most African countries, bridge deformation monitoring is not given priority and ultimately causes some bridges to collapse unexpectedly. In this paper we present a geodetic approach of bridge deformation monitoring of Lotsane bridge in Palapye, Botswana. The horizontal positions of reference and monitoring points were determined using Global Positioning System (GPS) while the height components were determined using precise leveling. The accuracy of the adjusted control points in x, y and z were 0.020m, 0.146m and 0.33m respectively. The final adjusted coordinates of the reference and monitoring points are presented and will be used for deformation monitoring of the bridge for the first epoch in 2020.
