Management of veld fires by newly settled farmers and related small-scale business opportunities

VD Westhuizen, C. January 2009 (has links)
Published Article / The central regions of South Africa experienced an abnormally high precipitation during the first quarter of 2009, thus resulting in an unusually high probability of veld fires due to the excessive amounts of fuel / grass available. In South Africa the process of land redistribution was recently drastically accelerated. This implies that many newly settled black farmers are fanning but still need to be trained in various aspects of farm management. Unfortunately, in most cases this training did not include environmental management, which among others, implies managing and preparing for veld fires. The Department of Water Affairs and Forestry also does not have sufficient funding to cover all these aspects and a regional collaborative plan must therefore be developed. In addition to this, in an attempt to alleviate poverty, many other previously disadvantaged people in South Africa must be assisted in establishing small business enterprises. This paper will highlight a process to be followed to train and coordinate all farmers and simultaneously establish business opportunities that will remove some of the fuel (grasses and shrubs) in order to reduce the risk and intensity of winter and spring veld fires.

Farmers' experiences and coping after disastrous veld fires in the North West Province / Herman Christiaan Johannes Becker

Becker, Herman Christiaan Johannes January 2014 (has links)
Research into the psychological consequences of natural disasters in South Africa remains largely unexplored. This is surprising, given the devastating economical and psychological ramifications that result from major catastrophic events. No research has been done relating specifically to the experiences and coping strategies of fanners who have experienced a veld fire disaster in South Africa. Farmers constitute an important sub-group for study as they may be psychologically at risk to the effects of disasters. In the international research arena exploration of the long-term consequences of disasters is lacking. In considering the question of coping following a disaster, few studies have focused on the influence of temporal dynan1ics, which would seem to be crucial to the outcomes of coping strategies. This study aims to address these gaps in the literature by exploring the experiences and coping strategies of farmers who have experienced a veld fire disaster which occurred in the North West Province of South Africa on 23 August 2011. The total financial loss as a result of the fire amounted to R42 276 I 71. The fires were allegedly caused by damaged power lines, which produced sparks and ignited the nearby veld. This study used a qualitative design. This methodological approach was adopted for its ability to capture the complex and time-sensitive dynamics of coping strategies. This was combined with a case study approach, based on the experiences and coping strategies of eight farmers who had experienced a veld fire disaster within the boundaries of one geographical area. Semi-structured interviews were conducted with the farmers in their homes and were recorded, transcribed and thematically analysed. The results of the analysis showed that the farmers progressed through three time periods with distinct patterns of experience and corresponding coping strategies. The person environment relationship, as well as transitioning situational demands inherent in this relationship, were found to be crucial in determining the outcomes of the fanners• experiences and coping strategies. The results also suggest that successful coping is reliant on the individual’s ability to continually adapt their coping strategies in a context-appropriate manner. It is recommended that psychological debriefing should be avoided and that crisis intervention teams (CIT) should focus on the long-term consequences of the veld fire. Future coping research needs to take the temporal aspects of coping into account. / MA (Research Psychology), North-West University, Potchefstroom Campus, 2014

Assessment and analysis of wildfires with the aid of Remote Sensing and GIS

Vorster, Willem Adriaan 12 1900 (has links)
Wildfires destroy large tracts of veld and forest land every year in South Africa. These fires can be devastating, resulting in loss of human lives, the destruction of property and the loss of income, for example the forest fire in the Sabie district in Mpumalanga in 2007 which destroyed about 7% of South Africa’s forested areas. There are frequently legal disputes with respect to the origin of wildfires, the extent of the fire and the land cover destroyed by the fires. The forensic capabilities of remote sensing in detecting and analysing post-wildfire characteristics have become an important contribution towards solving such legal disputes and in understanding wildfire characteristics. These post fire products can be used as evidence in court cases. Most of the time those court cases came up a few years after the fire event. By then, little or no evidence can be found on the terrain where the fire was. Remote sensing archives provide a reliable source of data that can be used to analyse these events after these long intervals. The objective of this project is to highlight the methods used to generate these post-wildfire analysis products. / Environmental Sciences / M. Sc. (Environmental Science)
