- Description: The phenomenon of arable field abandonment, a complex and multifaceted aspect of land use dynamics, has become a subject of increasing significance in rural landscapes. Across diverse geographic contexts, the abandonment of once-cultivated fields is indicative of transformative shifts in agricultural practices, reflecting the interplay of numerous socio-economic, environmental, and cultural factors. The abandonment of arable fields in the former homelands of the Eastern Cape and KwaZulu-Natal poses a multifaceted challenge with significant social implications. Historically, agriculture has been central to these regions, yet recent trends show a shift from traditional field cultivation to alternative practices such as garden cultivation or complete cessation. This shift has heightened vulnerability to food insecurity, hunger, and poverty, particularly as high unemployment levels exacerbate the situation. Moreover, the intricate relationships between humans and their surrounding ecosystems is also affected. Therefore, understanding the drivers of arable field abandonment at the community or household level can reveal localised factors that differ from broader, generalised drivers identified in previous studies. Additionally, examining the diverse impacts on these communities is crucial for developing targeted interventions that address their specific needs and enhance resilience. This study investigates arable field abandonment in specific villages of Gotyibeni and Melani in the Eastern Cape and Manqorholweni and Mawane, in KwaZulu-Natal. Using the Driving forces, Pressures, State, Impacts, and Responses (DPSIR) framework as a conceptual framework uncovers the driving factors, pressures, state, impacts and responses of this phenomenon in these rural villages. The study’s main aim was to assess the social effects of arable field abandonment in the selected study areas. The main objective is to determine how livelihoods, social relationships, and living conditions within and between households have changed following the cessation of field cultivation. The study also employed several specific objectives: first, to identify trends in field cultivation within the study areas; second, to analyse the drivers contributing to arable field abandonment in the villages; third, to examine the impact of field abandonment on the elderly population over the past 50 years; and fourth, to investigate the level of youth engagement in agriculture, including how the abandonment of arable fields affects their participation and perceptions of agriculture as a livelihood. To achieve the objectives the study employed mixed research methods that combine satellite imagery analysis, household surveys, oral history interviews with elders, most of whom had stopped farming, and youth focus group discussions. Landsat 7 Satellite imagery with a 15-meter spatial resolution was sourced from the South African Space Agency (SANSA) for the four study areas. The temporal coverage spanned from 1972 to 2020, with considerations for image usability based on resolution. Unfortunately, many earlier images were deemed unusable due to low resolution, particularly affecting Gotyibeni, where clear images only became available from 2013, therefore for this village the focus was on two decades. Arable fields, residential areas, homestead gardens, grasslands, and shrublands were classified. Change detection utilised a post-classification approach, comparing land cover categories between the early and late 2000s. A change detection matrix and statistics were generated using a ha/year formula, enabling the quantification of land cover changes. Image analysis employed ArcGIS 10.8.1 software for mapping and classification, involving georeferencing, signature file creation, maximum likelihood classification, and conversion from raster to vector formats for area calculations. For the LULC change matrix, an intersection analysis in ArcGIS overlaid data from different time points, and a pivot table in Excel organised resulting data. A focus on arable land changes, particularly conversions to other land uses, was crucial, as the study is investigating the level of arable field abandonment in these areas, understanding how much arable land has been converted or remained unchanged provides a clear indication of the extent of abandonment. To understand driving forces of arable field abandonment, a semi-structured questionnaire was developed based on the Driving forces, Pressures, States, Impacts, and Responses (DPSIR) framework. The questionnaires were administered through household interviews conducted in the four study villages. Sections of the questionnaire covered household involvement in cropping, perceptions of land use change, abandonment of field cultivation, and socio-economic demographics. Sampling involved a random selection of 20% of total households in each village, with data analysis performed using Statistical Package for Social Sciences (SPSS). Chi-square tests and Kruskal-Wallis analysis were employed to assess differences between villages. A second questionnaire specifically targeting households that had abandoned field cultivation was also done. Ninety-seven interviews were conducted to evaluate economic, health, socio-cultural and environmental impacts from respondents that indicated to have ceased field cultivation. Data analysis through SPSS utilised descriptive statistics and chi-square tests to identify statistically significant differences between villages. Oral histories were collected from elderly individuals in each village from a sample size of 15 individuals who were previous cultivators of fields, selected with the assistance of a village leader. The selected elders provided qualitative insights into historical and contemporary experiential aspects of village life. The focus was on changes in village relations, the environment, generational values, and traditional farming practices in each village. Youth-focused group discussions were organised with 30 young people in the village between the ages of 18-35, covering topics such as youth goals, the importance of field cultivation, and perceptions of the future. Both the oral histories and focus group discussions conducted in the local languages, were tape-recorded, transcribed, and subjected to content analysis to identify and interpret themes and patterns. The approach involved coding sentences, grouping codes into sub-themes, and further organising them into categories and subcategories. The LULC change results showed a consistent trend of significant arable land reduction across all villages, accompanied by a notable increase in grassland cover. Manqorholweni experienced the most significant loss of these arable fields. This finding was further supported by the household interviews which revealed 100% abandonment of fields in this village. Grasslands emerged as the dominant land cover in all villages, overtaking arable fields and homestead gardens. Regarding field abandonment, 76% of households across villages left fields unused for over 19 years due to reasons including lack of fencing, animal damage to crops, and financial constraints, despite recognising the socio-economic importance of field cultivation. Respondents expressed interest in returning to cultivation if the state would assist with fencing materials and costs. Concerns such as loss of cultural identity due to field abandonment were raised, especially in Manqorholweni, Mawane, and Melani. Homestead gardens were identified as a compensating strategy, with 78% of respondents actively maintaining them, although LULC change results indicated a decline, except in Mawane. Field cultivation revealed gender, age, and educational disparities, with non-cropping households having more female heads, individuals above 55, and higher proportions with only primary education. Households that abandoned field cultivation reported a decline in economic stability, with 97% experiencing less stable household economic circumstances. Unemployment was prevalent, with over 70% relying on social grants, creating financial challenges for 76% lacking sufficient cash. Limited off-farm formal employment (20%) was observed, while remittances played a minor role, this resulted in insufficient monthly income, affecting 94% of respondents. Dietary diversity declined, and reliance on store-bought food led to health concerns. Field abandonment impacted family dynamics, altering power relationships and reducing interaction, also heightened by COVID-19, affecting cultural identity and community cohesion. Youth across villages were not currently engaged in field cultivation or farming but expressed interest in revitalising agriculture. They recognised the socio-economic significance of agriculture and highlighted the importance of capital, resources, and government support. Challenges for youth involvement included lack of information, absence of agricultural advisors, and disparities in access to credit. Lack of support from elders and limited sharing of agricultural knowledge further hindered youth's ability to initiate farming projects. In conclusion, this study highlights the significant issue of arable field abandonment in rural areas of the Eastern Cape and KwaZulu-Natal, reflecting broader socio-economic and environmental transformations. The consistent reduction in arable land across the studied villages, coupled with the rise in grassland cover, underscores a critical shift from traditional agricultural practices to alternative land uses. The abandonment of fields has had profound impacts on community livelihoods, leading to decreased economic stability, reduced dietary diversity, and weakened social and cultural ties. The findings reveal a clear need for targeted interventions to address the specific challenges faced by these communities, particularly regarding food security and economic resilience. To address the challenges of arable field abandonment, it is crucial to implement a multi-faceted support program. This should include providing essential resources such as fencing, irrigation systems, and agricultural tools to facilitate field cultivation. Additionally, engaging and supporting youth in agriculture through training, access to advisors, and financial aid is vital to revitalise interest in farming. Strengthening social safety nets by enhancing financial support systems can mitigate economic challenges faced by affected households. Furthermore, initiating cultural and educational programs to preserve traditional farming knowledge while integrating modern practices will help maintain cultural identity and community cohesion. These measures are key to improving resilience and livelihoods in the context of field abandonment. , Thesis (PhD) -- Faculty of Science, Environmental Science, 2025

- Description: The prevalence of hunger and malnutrition has been steadily increasing in the world over the past decades. The rate of food insecurity was further exacerbated by the COVID 19 pandemic which plunged millions more into hunger as a result of a recovering economy and high food prices. These challenges are mostly experienced in Africa and are estimated to worsen in this region already affected by conflict, poor healthcare, and natural disasters such as floods and droughts. The green revolution in the 1960’s elevated agricultural production to play a pivotal role in the provision of food. However, production focused mainly on the cultivation of staple crops such as rice, wheat, and maize. The reliance on these crops has contributed to the lack of micronutrient intake and consumption of non-diverse diets. Wild edible plants (WEPs) which previously formed a significant part of indigenous people’s diet, have been regarded as an important food source crucial for the alleviation of malnutrition and micronutrient deficiencies. Despite their nutritional qualities, they are often ignored, overlooked, and undermined by agricultural programmes and food security interventions. Additionally, WEPs are largely absent in modern diets, they are often surrounded by negative perceptions, they are economically undervalued, and the indigenous knowledge of these species is under threat. As a result, this study regards WEPs as important resources that can significantly contribute to improved livelihood outcomes such as income, food security and good health. Using the Sustainable Livelihoods Framework, this study evaluated the contribution of WEPs to sustaining livelihoods, providing economic value, and examined how WEPs are perceived as well as the relationship between their knowledge and consumption in rural areas. This study was conducted in rural villages that are under the jurisdiction of the Moletjie and Matlala tribal authorities in the Polokwane and Aganang local municipalities, South Africa. Qualitative and quantitative research methods were employed for data collection. A total of 356 participants were interviewed for this study. Firstly, in-depth interviews were conducted with 20 elderly participants (Chapter 2). Semi-structured interviews were conducted with a total of 120 participants stratified by age, gender, and income groups (Chapter 3). A total of 96 household surveys were conducted in selected villages, this was complemented by direct observations and field surveys of the home gardens (Chapter 4). Questionnaires and freelists were administered to a total of 120 participants also stratified by age, gender, and income groups to collect data on indigenous knowledge of WEPs (Chapter 5). Thematic analysis were performed for interview data (Chapter 2) and data were summarised, descriptive statistics, chi square tests (Chapter 3), Kruskal-Wallis tests (Chapter 4), ANOVA tests and correlation tests (Chapter 5) were performed using SPSS software. The findings show that there has been a major nutrition transition characterised by changed meal composition, patterns, and frequency relating to the consumption of WEPs. The changes can be attributed to increasing western influence characterised by rising urbanisation, western lifestyle of church, school, and employment in an income-based economy dependent on retail stores to fulfil their daily dietary needs. Despite this, WEPs are still valuable to rural people, this is indicated by the fact that traditional foods are made optional at some modern and traditional celebrations. Overall, most of perceptions (65.6%) regarding the consumption of WEPs were positive. The overwhelming majority of respondents agreed or strongly agreed that preparations from the local WEPs are relatively more tasty (98.3%), healthy (96.6%), nutritious (86.7%), and better represent the traditional foods (94.1%). Additionally, participants perceived WEPs to have health benefits in that they have medicinal properties to help prevent diseases, are a good source of energy, highly nutritious and they give strength. Despite these benefits and positive perceptions, most participants expressed doubt over the commercial success of WEPs if they were to compete with cultivated crops in the market. As a result, they perceive the future of WEPs to be bleak as 95% of participants believe that their consumption is in decline. This can be largely attributed to deagrarianisation, climate change, and preference of cultivated foods by the youth. The study also showed that a diversity fruits and vegetables are available in rural home gardens, with cultivated fruits grown in abundance and WEPs available in almost all households (98%). WEPs represented 34% of the total estimated economic value of plants available in rural home gardens. Most of the home gardens produce food to supplement household food supply with only a few households engaged in trading. The trading of WEPs was recorded in 9% of the home gardens while 16% sold cultivated fruits and/or vegetables. Challenges such as lack of water and poor rainfall are shocks which affect the availability, richness, and abundance of home garden produce. WEPs are generally well known in rural areas as participants listed an average of 8.4±2.4 species. There was a significant statistical difference between the number of species listed by age group (p = 0.009) with the elderly listing a higher average number of species (9.3±2.6) compared to adults (8.1±2.5) and the youth (7.8±1.7). Vangueria infausta, Sclerocarya caffra, Ximenia caffra, Amaranthus retroflexus L. retroflexus, Citrullus lanatus,and Cleome gynadra where among the top listed species. There was also a significant positive correlation between the number of listed fruits with number of listed vegetables. The study also found a positive correlation between knowledge of WEPs and consumption. Most of the knowledge about WEPs was learned from a family member (89%), own observation (86%), a village elder (75%). This knowledge was mostly acquired from childhood through oral tradition (63%) and through participation (21%), and consumption (12%). , Thesis (PhD) -- Faculty of Science, Environmental Science, 2024
