Farmers on approximately 75% of Limpopo smallholder schemes are currently engaging in land exchange transactions in a highly insecure and un-formalised institutional setup. Land exchange prevalence longer than two years was moderately associated with cropping intensity and strongly associated with commercialisation. This result has three important implications. First, it suggests that more land is utilised on the schemes when there is vibrant land-leasing activity. Secondly, schemes with a higher prevalence of long-term leasing seem to have a strong tendency to be more commercialised. Thirdly, the duration of the lease is significant, as neither single-season, nor annual leases yielded any positive associations, while those exchanges that were two years or longer, were associated with increased performance. These findings highlight the potential for longer-term land-exchange interventions to address the widespread low land utilisation on smallholder schemes, and to catalyse more commercially-oriented farming. An irrigation scheme typology was derived from the cluster analysis and was aligned to a contemporary irrigation farming typology. The key descriptors included technology type, purpose of farming and scheme management type. By matching scheme type to the farmer typology (or typologies), strategic decisions regarding technology choices for infrastructure, land, and water institutional interventions can be better informed. All schemes demand attention to the multiple factors required to achieve performance, not least water-tenure security, irrigation management organisational development, and infrastructure modernisation. Complexity was demonstrated by the finding that multiple factors contribute to success, and that there are many dimensions that change independently and have a cascading effect through the system in ways that are difficult to predict. Agricultural systems support to achieve productivity and profitability are essential for success. The research findings lead to the recommendation that, in addition, strategic planners must also consider the implications of the dominant factors of water-technology choices so that these are manageable, and the dynamics of farm-size change based on land exchange processes, in order to harness new opportunities to maximise irrigation scheme performance in future.]]> Thu 13 May 2021 11:26:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30738 Thu 13 May 2021 08:18:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30610 Thu 13 May 2021 07:33:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34081 Thu 13 May 2021 06:38:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:38482 Thu 13 May 2021 06:20:50 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30547 Thu 13 May 2021 06:10:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31148 Thu 13 May 2021 06:10:06 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30977 Thu 13 May 2021 05:13:22 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30027 5x105 K and >6x1021 W Hz-1 respectively.

Short-term boat-based surveys were conducted three times a year between June 2014 and December 2016, contributing to a total of 47 days of surveys divided into three locations: Amathole, Hluleka, and Pondoland, each containing a MPA. Density and group size data were analyzed for both species and photographic identification analysis was performed for photographs of bottlenose dolphin dorsal fins. Results indicate that animal and sighting density did not differ temporally (bottlenose dolphin: sighting density – p=0.398, individual density –p=0.781; common dolphin: sighting density –p=0.472, individual density – p=0.204). Environmental factors (sea surface temperature, depth, substrate, and distance from shore) appeared to have limited effect on individual and sighting density and group size for both species (p>0.05). Photographic identification of bottlenose dolphins resulted in 2149 individuals, with a 11.8% resighting rate, with the highest resighting rate within the Pondoland MPA (16.1%). The resighting count did not differ temporally between monthly survey based on generalized linear models (p=0.866), but did differ between study areas (p<0.0001). These results provide the first evidence of the occurrence of both species of dolphin off the Wild Coast, as they were sighted in this region in all survey months. There was no trend in density based on temporal or environmental factors, which suggests other factors are influencing their occurrence. Resightings of bottlenose dolphins within the area suggest that there is some degree of residency, though the majority of animals were only sighted on a single occasion and there was no plateau in the discovery curve. A total of 256 biopsy samples (bottlenose dolphins =128; common dolphins=128) were collected during boat-based surveys. Bottlenose dolphin samples were also collected from adjacent areas to the southwest (Algoa Bay, n=22) and northeast (KwaZulu-Natal (KZN), n=20) of the Wild Coast to investigate similarities and differences between these areas. Despite a high degree of niche overlap between the two species (41%), common dolphins fed with a broader niche (standard ellipse area probability 0.89) than bottlenose dolphins in the summer and a narrower niche in the winter (probability 0.94). There was a clear spatial variation in the diet of bottlenose dolphins along the coast, with individuals from Algoa Bay and Amathole demonstrating 0% niche overlap with individuals from KZN, but the mechanism for these differences remains unclear as other species from South African waters demonstrate a strong southwest to northeast gradient in nitrogen for the Eastern Cape coastline. This research provides valuable baseline information regarding dolphins off the Wild Coast of South Africa, which remained largely unknown. My results indicate that bottlenose dolphins may be more resident in the Wild Coast than previous predicted, and confirm that common dolphins are highly mobile in this area.]]> Thu 13 May 2021 03:09:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31150 Thu 13 May 2021 01:49:42 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29121 Thu 13 May 2021 01:46:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30766 Thu 13 May 2021 01:36:46 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30939 Thu 13 May 2021 01:36:33 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29662 Thu 13 May 2021 01:34:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34216 Thu 13 May 2021 01:21:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31125 Thu 13 May 2021 00:57:02 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30972 Thu 13 May 2021 00:55:59 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42819 Thu 11 Aug 2022 06:50:48 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:40637 Thu 01 Feb 2024 09:12:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44674 Sat 04 Dec 2021 12:18:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:35847 Mon 29 Apr 2024 11:54:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:35797 Mon 29 Apr 2024 11:49:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71863 Mon 29 Apr 2024 11:45:07 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:32509 Mon 15 Aug 2022 16:12:51 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:38430 Mon 13 May 2024 15:15:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:35959 Mon 13 May 2024 14:25:29 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:40100 Mon 08 Aug 2022 21:09:15 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:40172 Fri 26 Apr 2024 12:30:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:37915 Fri 26 Apr 2024 11:15:59 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:37916 Fri 26 Apr 2024 11:13:46 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:37918 Fri 26 Apr 2024 11:13:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:37901 Fri 26 Apr 2024 11:11:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:40171 Fri 26 Apr 2024 11:09:16 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71508 Fri 26 Apr 2024 11:01:35 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71454 Fri 26 Apr 2024 10:58:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72099 Fri 26 Apr 2024 09:40:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72452 Fri 17 May 2024 07:33:37 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71348 Fri 10 May 2024 14:40:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71344 Fri 10 May 2024 14:36:11 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71299 Fri 10 May 2024 14:34:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:68574 Fri 10 May 2024 12:53:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:68535 Fri 10 May 2024 12:53:06 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:43128 Fri 10 May 2024 07:39:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42822 Fri 10 May 2024 07:38:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:43081 Fri 10 May 2024 07:37:52 SAST ]]>
