This document consists of 17 printed pages. © UCLES 2020 [Turn over Cambridge International AS Level ENVIRONMENTAL MANAGEMENT 8291/11 Paper 1 May/June 2020 MARK SCHEME Maximum Mark: 80 Published Students did not sit exam papers in the June 2020 series due to the Covid-19 global pandemic. This mark scheme is published to support teachers and students and should be read together with the question paper. It shows the requirements of the exam. The answer column of the mark scheme shows the proposed basis on which Examiners would award marks for this exam. Where appropriate, this column also provides the most likely acceptable alternative responses expected from students. Examiners usually review the mark scheme after they have seen student responses and update the mark scheme if appropriate. In the June series, Examiners were unable to consider the acceptability of alternative responses, as there were no student responses to consider. Mark schemes should usually be read together with the Principal Examiner Report for Teachers. However, because students did not sit exam papers, there is no Principal Examiner Report for Teachers for the June 2020 series. Cambridge International will not enter into discussions about these mark schemes. Cambridge International is publishing the mark schemes for the June 2020 series for most Cambridge IGCSE™ and Cambridge International A & AS Level components, and some Cambridge O Level components.

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 2 of 17 Generic Marking Principles These general marking principles must be applied by all examiners when marking candidate answers. They should be applied alongside the specific content of the mark scheme or generic level descriptors for a question. Each question paper and mark scheme will also comply with these marking principles. GENERIC MARKING PRINCIPLE 1: Marks must be awarded in line with: • the specific content of the mark scheme or the generic level descriptors for the question • the specific skills defined in the mark scheme or in the generic level descriptors for the question • the standard of response required by a candidate as exemplified by the standardisation scripts. GENERIC MARKING PRINCIPLE 2: Marks awarded are always whole marks (not half marks, or other fractions). GENERIC MARKING PRINCIPLE 3: Marks must be awarded positively: • marks are awarded for correct / valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team Leader as appropriate • marks are awarded when candidates clearly demonstrate what they know and can do • marks are not deducted for errors • marks are not deducted for omissions • answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the question as indicated by the mark scheme. The meaning, however, should be unambiguous. GENERIC MARKING PRINCIPLE 4: Rules must be applied consistently e.g. in situations where candidates have not followed instructions or in the application of generic level descriptors.

Mark scheme, page 3

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 3 of 17 GENERIC MARKING PRINCIPLE 5: Marks should be awarded using the full range of marks defined in the mark scheme for the question (however; the use of the full mark range may be limited according to the quality of the candidate responses seen). GENERIC MARKING PRINCIPLE 6: Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be awarded with grade thresholds or grade descriptors in mind. Science-Specific Marking Principles 1 Examiners should consider the context and scientific use of any keywords when awarding marks. Although keywords may be present, marks should not be awarded if the keywords are used incorrectly. 2 The examiner should not choose between contradictory statements given in the same question part, and credit should not be awarded for any correct statement that is contradicted within the same question part. Wrong science that is irrelevant to the question should be ignored. 3 Although spellings do not have to be correct, spellings of syllabus terms must allow for clear and unambiguous separation from other syllabus terms with which they may be confused (e.g. ethane / ethene, glucagon / glycogen, refraction / reflection). 4 The error carried forward (ecf) principle should be applied, where appropriate. If an incorrect answer is subsequently used in a scientifically correct way, the candidate should be awarded these subsequent marking points. Further guidance will be included in the mark scheme where necessary and any exceptions to this general principle will be noted.

Mark scheme, page 4

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 4 of 17 5 ‘List rule’ guidance (see examples below) For questions that require n responses (e.g. State two reasons …): • The response should be read as continuous prose, even when numbered answer spaces are provided • Any response marked ignore in the mark scheme should not count towards n • Incorrect responses should not be awarded credit but will still count towards n • Read the entire response to check for any responses that contradict those that would otherwise be credited. Credit should not be awarded for any responses that are contradicted within the rest of the response. Where two responses contradict one another, this should be treated as a single incorrect response • Non-contradictory responses after the first n responses may be ignored even if they include incorrect science. 6 Calculation specific guidance Correct answers to calculations should be given full credit even if there is no working or incorrect working, unless the question states ‘show your working’. For questions in which the number of significant figures required is not stated, credit should be awarded for correct answers when rounded by the examiner to the number of significant figures given in the mark scheme. This may not apply to measured values. For answers given in standard form, (e.g. a × 10n) in which the convention of restricting the value of the coefficient (a) to a value between 1 and 10 is not followed, credit may still be awarded if the answer can be converted to the answer given in the mark scheme. Unless a separate mark is given for a unit, a missing or incorrect unit will normally mean that the final calculation mark is not awarded. Exceptions to this general principle will be noted in the mark scheme. 7 Guidance for chemical equations Multiples / fractions of coefficients used in chemical equations are acceptable unless stated otherwise in the mark scheme. State symbols given in an equation should be ignored unless asked for in the question or stated otherwise in the mark scheme.

Certain habitats at risk- shallow streams dry out reducing habitats for invertebrates, soils dry out and crack reducing strength and increasing susceptibility to soil erosion, may lead to mass movement when rains return. • Low temperatures – Environmental, increased fossil fuel combustion to meet energy demands, food scarcity for animals, break down of soil structure by freezing and thawing causing soil erosion. Contrast management MEDC – early reporting allowing preparation, stockpiling resources, members of the public likely to be able to provide food supplies for many days, vulnerable people supported by professionals, homes well insulated to maintain comfortable temperature inside, planned power cuts if necessary, in cold weather extra support for homeless. LEDC’s – May require foreign aid to provide emergency food water provision, less dependent on fossil fuels so more consistent demand, shorter distances travelled to work therefore less disturbance of commute, greater shortage of food as food not so abundantly available. 30 Please Use Level Descriptors 2

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 10 of 17 Question Answer Marks 4(a) precipitation and crop yield- peaks in precipitation correspond to peaks in crop yield, for example 1963, 1977, 1987, 1992, 1997, 2007. following a high precipitation year yield remains high for next year although precipitation may not be high. peaks in hot days correspond to low yield years, 1964, 1976, 1990, 2003, effect is not sustained for following years. Overall trend in yield increases from 1960 to 2010. High levels of precipitation cause high yield because water required for photosynthesis. photosynthesis required to make the sugars which will form the starch stored by plant as the maize. improve flow of minerals in groundwater, improve soil quality prevent cracking degradation. High temperature causes drying out and damage to plants, increased evaporation of water therefore insufficient for photosynthesis, soil is cracked and damage plants are less stable. 10 Please Use Level Descriptors 1

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 11 of 17 Question Answer Marks 4(b) The question requirements are: • to describe agricultural practices which can be used • evaluate the use of these practices. • discuss differences in managing soils between high / low income economies Practices – Increasingly plant based diet to reduce demand for growing feed for livestock, improve efficiency in energy transfers, smaller scale farming growing mixed crops, use smaller less damaging machinery, eating food in season, improved irrigation systems, time allowed for fields left fallow, contour ploughing, hedgerows planted, organic material left in field to improve soil structure, maintain drainage, maintain soil cover, minimum tillage (digging at appropriate time), increase or maintain organic matter, add manure, delay ploughing, minimise compaction. high income economies, high demand on land, less land available for agriculture as urbanisation occurs, farming needs to be more intensive to provide for increased population using a smaller area, increased proportion of land is contaminated when moving from an industrial history, reduction of hedgerows and wildflowers on field margins to allow for large machinery to work fields, competition between producers force prices down less funds available for conservation projects, large contracts with retailers difficult to manage sustainably. increasing use of agrochemicals impacts on soil structure, clearance of organic material means less added to soil, damages texture and increasing vulnerability to soil erosion. low income economies, increasing demands on agricultural land from growing biofuels and crops for export, less available time for fields left fallow, less opportunity for soil structure to develop and therefore easily eroded during flash flooding, longer periods of drought due to climate change causes damage and desiccation of soil, poor sanitation systems may leak and cause contamination of soil, waste disposal poorly managed causing leachates, heavy metals to reach soil and water system. Less investment in scientific and technological solutions. 30 Please Use Level Descriptors 2

8291/11 Cambridge International AS Level – Mark Scheme PUBLISHED May/June 2020 © UCLES 2020 Page 13 of 17 Question Answer Marks 5(b) The question requirements are: • to discuss sustainable use of areas of outstanding natural beauty • to discuss conflict between land users • to evaluate situations where conflicts are managed areas of outstanding natural beauty are areas which may be used for conservation purposes and are often state owned. Sustainable use allows the area to be enjoyed and experienced today without impeding the enjoyment of others in the future. Restriction exist in terms of mineral exploration, farming, development, planning guidelines, education services in parks provide a sustainability plan by inspiring future generations. Conflicts between users. Farming – May have a long history of farming in an area later classified as an area of outstanding natural beauty. – access conflicts between activities and areas with livestock – challenges transporting goods out in tourist traffic – conservationists appose use of agrochemicals, farmed areas rather than a natural habitat. – pollution of water ways effect recreational activities Exploration – Large vehicles and machinery accessing delicate ecosystems. – noise from blasting/ dust from mine / quarry – areas of park would need restricted access.
