For nature-based tourism, weather determines the timing and variety of activities, while longer-term climate affects the seasonality of both tourism arrivals and the natural environment tourists will experience. This influence is heightened in developing countries, where little adaptation has been implemented to ameliorate unfavourable climate and extreme weather events. The Tourism Climatic Index (TCI) is widely used in the global North to quantify the climate suitability of tourist destinations. Initial studies for South Africa, Lesotho and Namibia reveal the applicability of the index in the African context, despite challenges in data availability and quality. This study presents the first TCI calculations for Zimbabwe, a country relient on outdoor nature-based tourism for attracting tourists and foreign income. The mean annual TCI scores classify Zimbabwe as very good to excellent in climatic suitability for tourism, with scores spanning 75.5–83 (of a maximum 100) for the period 1989–2014. Monthly TCI scores categorize four locations in the Lowveld region as having a winter-peak suitability; the remaining stations have either summer-peak or bimodal shoulder-peaks. This reveals year-round climatic suitability for tourism in Zimbabwe, and highlights the importance of understanding seasonal variability per destination to maximize tourist satisfaction.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"5 8","pages":"443 - 463"},"PeriodicalIF":1.4,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03736245.2020.1835703","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72396914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluate its application in aerosol studies by comparing surface and airborne samples from the Makgadikgadi Pan in Botswana. The playa is a major global dust emitter and its aerosols have a widespread effect on atmospheric, biological and terrestrial processes. Sampling was conducted at a carefully selected surface location and associated BSNE dust trap stack at 0.25, 0.5, 0.85 1.65 meters. The dominant minerals identified here are quartz, halite, thernadite, mica, calcite and feldspar. Surface sample results from QEMSCAN are in line with other forms of elemental and mineralogical analyses. When comparing surface samples with elevated trap samples, we noted a fining and fractionation during grain entrainment, resulting in a compositional shift with height. We also observed some ultra-fine fraction losses from the BSNE traps. Overall, the single location here establishes the link between fluvial playa basin inputs, sediment storage, evaporation products and aeolian losses and outputs from a dry lake surface, not unlike semi-arid evaporative dust sources elsewhere.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"23 1","pages":"7 - 21"},"PeriodicalIF":1.4,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82992051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adoption of voluntary landscape scale conservation initiatives, such as the South African conservancy model, offers a possible solution. This article uses the Grootvadersbosch Conservancy as an example of how the gap between agricultural productivity and landscape conservation can be bridged. The objectives were to: investigate the conservancy’s historical context; discover the stakeholders’ motivations for joining the conservancy; identify the successes of the conservancy’s projects; and determine the effects of these on the landscape. Three methods were used: a literature study; semi-structured interviews with seven of the conservancy’s management staff who were identified using the snowball sampling technique; and a questionnaire survey distributed to the 21 members of the conservancy, of which 16 replied. The results showed the study area has a long history of environmental exploitation, which led to the establishment of the conservancy. The main reason why conservancy members joined was because of their conservation values. Their four successful landscape scale projects delivered several environmental, social and economic outcomes that positively affected the landscape. It is therefore recommended that farmers create conservancies using a similar model to reconcile the environmental demands of agriculture with the need to improve affected environmental assets and natural resources.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"149 1","pages":"372 - 388"},"PeriodicalIF":1.4,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79397887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reviewed the existing knowledge of the threats posed by closed and abandoned mines to natural and human environments in Namibia and identified current limitations and constraints to mine rehabilitation. The exposure of ecosystems and communities to more than 250 abandoned mines is a significant hazard throughout the country. At the same time, mining is one of the largest sectors contributing to Namibia’s economy. The legal framework related to mine rehabilitation is fragmented and incomprehensive and has failed to protect the environment from adverse impacts of mining. Other constraints to successful planning and implementation of mine rehabilitation include lack of knowledge, skills, cooperation, and funding. A more holistic approach is needed to address complex challenges related to the abandoned mines. Improving the current situation would require better integration of mining and environmental legislation, training and recruitment of mine rehabilitation experts, monitoring the long-term effects of mining, international collaboration, and implementing a binding financing mechanism for mine rehabilitation.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"14 1","pages":"389 - 405"},"PeriodicalIF":1.4,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80713036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The merits and demerits of PWMs continue to be debated, and more empirical information will help chart a new course especially in smaller cities in poor countries. The paper adopts a qualitative research design and case study approach in eliciting information from respondents. Water governance institutions and 35 residents in Karoi town were purposively sampled to understand how they viewed the impact of PWMs installation in the water supply chain. Data collection tools included questionnaires, documents, observations and focus group discussions (FGDs). Findings revealed that respondents perceived water is an indispensable commodity, a right and one that should be enjoyed by every citizen regardless of their social or economic status. The installation of PWMs also runs contrary to the Zimbabwean Constitution as it deprives low-income citizens of water if they could not afford to pay. Instead, a more appropriate delivery mechanism is the traditional post-paid system, which allows consumers to access water based on affordability.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"6 1","pages":"356 - 371"},"PeriodicalIF":1.4,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81956550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A core one is amelioration of the urban heat island effect. However, the many estimates from temperate regions cannot be extrapolated to the tropics, where more empirical studies are required to guide urban planning and optimization of green infrastructure design and distribution. This study reports on the temperature differentials in fortnightly readings, in winter and summer, between 12 urban green spaces and the surrounding built-up urban matrix at increasing distances from each green space. Additionally, the value of energy costs saved for air conditioning by urban greenery was calculated. The mean difference in temperature between green spaces and neighbouring built-up areas was 3.6°C, and in summer ranged from 0.9°C to 6.1°C and in winter 0.9°C to 5.7°C. The cooling effects extended up to 1.7 km beyond the centre of green spaces. The magnitude of cooling increased slightly with increasing green space size. These cooling effects translated into a cost on energy saving of approximately US$532/household/yr. Given the weak economy and incomes in Zimbabwe, this saving is considerable and can contribute to the multiple motivations for more green spaces in the city.","PeriodicalId":46279,"journal":{"name":"South African Geographical Journal","volume":"35 5 1","pages":"344 - 355"},"PeriodicalIF":1.4,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82797900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
