Building Nsanje Port on Shire Zambezi Waterway

Building Nsanje Port on shire Zambezi peeway device DescriptionMalawi is a landlocked country that relies on Mozambi dissolve ports on the Indian Ocean for transportation of imported and exported goods. The stomach forget open new doors for Malawi and sign up transport costs. Currently Malawi uses Beira and Nacala port in Mozambique from which transporters cover a return distance of ab proscribed 1700km from Blantyre. Using Nsanje port, transporters now will cover a distance of 238 km for a return journey to Blantyre as opposed to Beira port. Reduction in transport costs may lead to reduction of other goods such as agricultural in corrects. This will be a get ahead to the Malawians who depend on agriculture for their economy and it will also correct food security in the country.The befuddle will also depart Malawi with a multimodal transport linkage to other land locked countries of Zimbabwe and Zambia the spate of Nsanje district will be empowered soci tot allyy and econ omically due to new infrastructure and markets that will be established to support the services of the port the visual setting of Nsanje district will improve with the building of the port creation of temporary and permanent jobs time saving and reduction on give birth and tear of vehicles due to reduced travel distance.Though the project will have positive effect but will also have negative impactions such as loss of fishing field of view and income for fishermen who used to fish a eagle-eyed the shire river air and water supply pollution due to construction doing that will take place on the site the project will affect the water species imbed along this area of the Shire river empowerment of people socially and economically may increase the bedcover of HIV and AIDS as this districts already has high percentage of HIV patients due to cultural beliefs urbanization due to viable surroundings for small scale and large scale businesses inhering visual scenery will be affect ed by new built structures, risk to flooding along the Shire river conflicts with hosting communities and negative influences on religion and local culture. arrangementThe project will be located at Nsanje District in Malawi. Malawi is located between latitudes of 09 and 17 s turn uph and longitudes of 33 and 37 east. Malawi is bordered by Zambia in the East, Tanzania in the North and Mozambique in the South and West. Nsanje District Assembly is found at the cessation of Southern Malawi where Malawi shares borders with Mozambique. It is at this place that the shire river passes along the boundary between Malawi and Mozambique flowing into Zambezi river and then to Indian Ocean through Chinned Port. The site was selected because of the wider width of the river as it connects to Zambezi River offering a better place for the port. Location map is shown in relation to the Shire River and location for the proposed port.Malawi Map masking location of Nsanje, Imagery showing location of the port, Shire River and Nacala corridor from Mozambique.MALAWIS EIA LEGISLATUREIn Malawi the Environmental Act enacted in 1996, provides the legal framework for the defense and management of the environment, the conservation and sustainable utilization of natural resources. EIA processes are outlined on section 24 of the Act to which all private and public developers must adhere to. The Act has outlined projects for which EIA is mandatory in front implementation of the project as gazetted in section 24. The section also stipulates all activities that must be carried out by the developer before both implementation. The developer has to submit a project brief to the Environmental affairs Department (EAD) who administers the environmental Act. The Director assesses the project and is supported by expertness from the technical committee of environmental affairs ( investigator) which participate in the Environmental Impact Assessment (EIA) requirements project briefs reviews Terms of persona (ToRs) and EIA reports develop and monitor project auditing programme and recommended course of action to the Director though the director is non bound by the TEC report. The act also stipulates that only the EAD is mandated to issue out certificate chthonian section 26(3) for which an EAI is required.For thorough evaluation of project activities that might have significant impact on the environment by the port developer, the EIA is supported by assorted Malawi government Acts and policies as indicated in table 1 and other international legislatures as attached on appendix I.Malawi legal documents4.2 EIA ProcessThe EAI process is carried out in microscope stages in a project rack in which EIA requirements are integrated within the musical rhythm (EMA, 1996). The project cycle is carried out in phases and begins with a concept then pre-feasibility and feasibility studies before a detailed design and implementation phase. The objective of the cycle it to provide deta iled and up-to-date environmental selective information at key stages in the cycle. This helps the developer to cite early results from an EIA and able to take action on any significant changes and adopt them during project implementation. The project cycle also provides opportunity to the developer, consultant, relevant authorities, interested parties and the universal public to assess the impacts of the project on the environment and provide alternatives on adverse effects. The project cycle focuses on identification of negative impacts, reasonable alternatives and assessing the relevant issues so as to ensure that the EIA becomes a expedient to decision makers. All the activities in the project cycle are done through screening and scoping.4.1 covertScreening allows a project to be assessed whether an EIA is required or not and establishes the basis for scoping (Theodorsdouttir, 1999). In Malawi, screening is done through a project brief which is a document that highlights cr itical issues prepared by the developer and in this case the Malawi Government and is submitted to the Director of Environmental Affairs Department and who is supported by TEC to assess whether it requires EIA or not. Building of an inland port is among the projects that EIA is mandatory in Malawi therefore an EIA is to be carried out (EMA, 1996).4.2 ScopingScooping ensures that all relevant issues to be addressed in an EIA are established and makes sure that all relevant authorities, interested and affected parties are involved, alternatives to the project are identified and to make sure that the resources are conserve and used wisely. In Malawi, comprehensive identification of the significant impacts are based on the Terms of extension (ToRs) which are prepared by the developer and approved by the director (EMA, 1996). ToRs are identified in the scooping process. The take care I below outlines all the EIA process in Malawi.4.3 ASSESSMENT METHODThere are various methods of assessi ng environmental project impacts such as checklist, network diagrams, graphical comparisons overlays and matrices (FAO, 1995) In this assessment matrices as shown in figure 2 have been used to come up with the most significant impacts as matrices easily identify impacts in a summary form and provides better bases for evaluating most significant ones Leopold et al. (1971).4.4 Environmental intentImpacts identified in the matrices are further assessed by Stakeholders, EAD, TEC, general public and the developer to evaluate the impacts and also identify mitigation measures. In the environmental plan potential project impacts are identified in cipher to project phases as indicated in Appendix IIThe most significant impact Water pollutionThe most significant environmental impact on this project is water pollution. Water pollution is the defilement of water bodies through pollutants which are discharged directly into water bodies without adequate measures to remove harmful compounds. Water pollution may take place due to effluents derived from soil erosion, accidental spills, waste oil, fertilizers and detergents, heavy coat and pesticides, heat and micro-organisms (JICA/GOK, 1992).5.1 Significant ImpactsDrinking Water Water is considered safe if it can be used by pitying beings and other living creatures without any effect (UNEP, 1999). Polluted water is not safe for drink for the communities living along the river and can easily wipe away a large population of human beings and animals as the birds shown in figure3.Odour Sediments in the water under the structures may cause water stagnancy and after sometime the water may produce odours that may be nuisance to the people work around the areaImpact on irrigation Water polluted with chemicals and oil spills may affect irrigated crops. entertainment Polluted water will not be good for swimming or recreation as it may affect the people in contact with polluted water.To reduce water pollution, there is needine ss to provide mitigation and monitoring measures as shown in table III below.Significant impactProject ActivityPossible Mitigation measuresPrediction and Monitoring measuresWater pollutionLandfills and site development metrical site selection and layout design is important to reduce stagnation. Dredging should be carried out to remove any deposits and sediments in the waterEnhance the water law Act to punish offenders who deliberately pollute water manifestation of break waters, bays and terminalsMake a fence around the construction areaQuarterly meetings during the construction phase should be held to monitor the negative environmental impacts. TEC and EAD to monitor the activitiesDredging and disposal of dredged real(a)s fit disposal of dredged material plays an important role in preserving the environment.Monitor sediment deposits and use Secchi disk to check depth and visibility (United Nations, 1992).Waste ManagementEncourage recycling and devise proper means of disposing both solid and eloquent wasteDistrict Assembly to monitor all dumping sites and advise residents accordingly.Transportation of construction materialsProper handling of raw materials is required i.e.Cover cement and sprinkle water frequently on frigid roadsMonitor handling of the raw materials.Vessel traffic operationsAppropriate regulations should be put in place to cater for ship discharge, emissions and oil from incumbrance, ship spills and disposal of waste rehearse of atom-bomb remote sensing satellites and receivers aboard ship vessels to monitor ship movements, oil spills and grease and ship news leak in the river (Woodhouse, 2006).Use predictions models to monitor water quality such as imitation Intelligence models, Artificial Neural Network models and Mathematical assimilations (Najah et al., 2009)Cargo handling and storageSpecial equipment should be provided for handling freightage and transportation of goods and Provision should be made for periodical clean-up of floats and wastesDeveloper to monitor that cargo handling equipment is regularly servicedWaterfront and cargo operationsProvide regulations on effluent from waterfront industries and monitoring of water qualityTEC to monitor all activities probably by employing a full time environmental specialist.Transportation of goodsAll roads starring(p) to the port must have bitumen to avoid dust which may pollute the water.Stakeholders to monitor where they there expertise is required.5.2 Acts that govern the legislature for water areEnvironmental Management Act 1996 which stipulates the conservation and sustainability of utilization of natural resources and water is one of the natural resources.Water Resources Act 1969The act governs the control conservation, apportionment and use of water resources in Malawi.Water Works ActThe act makes an offence if any person willfully and negligently causes water pollution.5.3 Baseline dataBaseline data is the collection of relevant information proposed in the project with the purpose of determining the status and trends of environmental factors (e.g., water pollutant concentrations). This offers opportunities to predict changes in terms of importance and provide for means of detecting actual changes once the project is initiated. Baseline data plays an important role in EIA assessment and monitoring of environmental effects (Wathern, 1988).Alpha (1995) recommends the following data to be collected for checking water pollutionDissolved OxygenWater conductivityWater salinityTurbidityTemperaturePHUse of questionnaire to get more information from the communities around the district Assembly on the activities that take place along the riverMeasurements on sediments.Maps showing river catchments area5.3.1 Parameters for checking water qualityUNEP prescribes measurement of various parameters for assessing, water quality and these intromit-Temperature recommended is between 25 and 35Suspended solids it is recommended is 30mg/lBiochemical oxy gen Demand (5-day at 20 C) Clean water is between 4mg/l to 10 and more than 10 is considered pollutedHeavy admixture concentration should not exceed 0.1mg/l in combinationLead (PB) less than 0.1mg/lhydrargyrum (Hg) less than 0.005 mg/lSilver (Ag) , Zinc(Zn), Chromium (Cr), Arsenic (As) less than 0.05 mg/l atomic number 28 (nI) less than 0.3 mg/lCopper (Cu), Cyanides (CN), Hydrogen Sulphide (S) less than 1.0mg/lFree ammonia water (NH 3 ) less than 0.2mg/lPhenolic Compounds (Phenol) 0.001 mg/lNitrates (N) 10mg/lPhosphatesFloating materials oils foam and greases.Bhardwaj, 2005, point water quality criteria as shown in the table below5.4 GAPSMeasurement of water quality can only be undertaken by people with special expertise and with special equipment which cannot be used by a local person and the water measuring instruments are not up-to-date and not plentiful to cover all water bodies in the country (UNEP, 1999).ConclusionThis project has a significant impact on water which is crit ical to water species and human beings therefore mitigation measures have to be followed to reduce water pollution in the Shire river which its impacts may have an effect over a long distance and all the way to the Indian ocean and affect so many people and all water habitats.
