Critical factors determining successful irrigation farming in Lesotho

Ntai, P.J. (Palamang Joseph) 25 July 2012 (has links)
Lesotho has ample water resources which could be used to improve the livelihoods of Basotho as a nation in many aspects. However, this seems not to be the case as Lesotho suffers from food in security particularly during severe droughts, to an extent of seeking support from international communities. Therefore the purpose of the study was to identify and investigate critical factors that determine successful irrigation farming in Lesotho in order to uplift the performance of irrigation and livelihoods of Basotho. A structural questionnaire was administered amongst 153 irrigation farmers and 31 extensionists randomly in the four southern districts of Lesotho, namely Maseru, Mafeteng, Mohale’s Hoek and Quthing. The above mentioned districts were chosen because of the spacious agricultural land they have. Secondly most rivers with significant amount of water flow towards these areas. Irrigation farmers showed that households are engaged in a wide range of livelihood activities, both on-farm and off-farm (e.g, taxi, business, etc). In addition, they obtain a substantial portion of the household income from the state through pensions and social grants. Agriculture is an important livelihood activity among irrigation plot holders in the four districts. Maize, potatoes, cabbage and beans are the most common crops grown by irrigation farmers in Lesotho. 34% of the farmers perceive climate as the most important factor determining what crops to plant, while 29% of the respondents consider potential markets as an important factor with decision making. Farmers use hoeing as the main method of controlling weeds and involve family members as their source of labour. 64% of farmers use rivers as their main source of water while the rest use dams and boreholes. Irrigation water is free of charge with exception of the fewer farmers located in the Maseru district where they irrigate from the Mohokahare and Phuthiatsana rivers. Most farmers perceive irrigation as an expensive activity especially those who are using diesel and electricity to pump water from the rivers and dams. Evidence suggests that very few farmers (5%) and extensionists (3%) have received any training in terms of irrigation farming and maintenance of irrigation systems, marketing opportunities and farm entrepreneurship planning. Extension credibility is highly questionable as 70% of irrigation farmers do not regard extension as important for irrigation management decisions. Evidence further indicates that most farmers do not belong to any farmer groups/associations. 78% of extension workers indicate that the main problem hindering them from efficient extension delivery is the lack of infrastructure and facilities. These results suggest the need for greater political and institutional input in irrigation farming and in particular to revisit institutional policy instruments and institution for extension, technical assistance, training and credit services that will facilitate performance of irrigation farming in Lesotho. Most importantly, farmers and extensionists should be adequately trained on the economic use of water and how to preserve it for sustainable irrigation development.

A survey on external (Ixodidae) and gastrointestinal parasites of small ruminants on an arid communal rangeland in South Africa

Govender, Saloshnie Simone January 2020 (has links)
Magister Scientiae (Biodiversity and Conservation Biology) / Parasites pose a major constraint on livestock farming. Its impacts are represented as transmission of disease to humans and economic costs for prevention and treatment as well as loss in terms of; livestock mortality and, lowered productivity. Although the impacts of parasitic loads can be decreased through proper management, extensive management systems are depended on external factors such as rainfall and forage availability, which, in its absence, promote malnutrition and therefore parasite susceptibility.

The Effect of Relationship-building Programs on the Resilience of Women in Agriculture

Bertsch, Robert January 2020 (has links)
The purpose of this study was to describe the relationship between participation in relationship-building programs and online social groups, and the individual resilience of women in agriculture in the United States. Women have demonstrated a unique ability to connect farms and ranches with social resources, drive change and adaptation in agriculture, facilitate farm and ranch succession, and build community after a disaster. The capacity of agriculture and rural communities to adapt in the face of significant adversity depends on those unique abilities. Improving the resilience in women in agriculture is critical to the overall resilience of rural America. Unfortunately, most resilience interventions focus on internal psychology and do not address external, social-ecological factors for resilience. The results of this study show participation in certain relationship-building programs is associated with a significant increase in the level of some external resilience factors among women in agriculture in the U.S.

"If we can't grow rice, then what?": Farming Livelihoods in the Production of Vietnam's Rice Farming Landscapes

Sarah D Huang (9733271) 15 December 2020 (has links)
<p>This dissertation challenges dominant food security discourses and practices that seek to address food insecurity through technoscientific approaches to agricultural production. Situated in Vietnam’s An Giang province in the Mekong River Delta, this work ethnographically explores and historically grounds global, national, and household scalar implications of these same discourses and practices on rice farmers’ livelihoods. The central research question that guided this project asks: if farmers are producing security for the nation, then why do they remain food insecure? Through a 16-month ethnographic study utilizing a mixed-methods approach I combined participant observation, household surveys, semi-structured interviews, and participatory mapping with rice farmers, farm laborers, and local and national government officials in order to address this question from a historically and ethnographically ground perspective. I show how Vietnam’s history of hunger and famine, experienced most recently in the late 1970’s, colors the nation’s current and future agricultural development. Focused on a future of rural development, economic growth, and values of modernity, new models of agricultural production are implemented across the Mekong River Delta to ensure the nation’s self-sufficiency in producing “enough” rice and food. Amongst these strategies, intensive triple cropping rice practices, food safety certifications and practices, and an increased reliance on agro-chemicals has resulted in differing farming practices and mixed impacts on farming livelihoods. I leverage a feminist political ecology and science and technology studies framework to foreground the rice farmers’ perspectives and differed experiences, while tracking the rooted inequalities within government policies, market logics, and social relationships. In three articles, I (1) examine differential experiences of state-based agricultural models and their impact on farmers’ livelihood security (2) trace how dominant discourses raise questions about individual and state responsibility; and (3) explore emergent farming livelihood opportunities and challenges within late socialist agricultural development. Drawing on ethnographic accounts and experiences, particularly from farmers, results showed that these dominant discourses that narrows food security to only be governable through techno-scientific approaches and agricultural practices are insufficient to address farmers’ insecurity.</p>

Tasteless, Cheap, and Southern?: The Rise and Decline of the Farm-Raised Catfish Industry

Senaga, Karen 07 May 2016 (has links)
This dissertation traces the rise and recent decline of the farm-raised catfish industry. From the 1960s to the 2000s, farmers and scientists reengineered the river catfish into an agro-industrial food crop. Through extensive agricultural scientific research and marketing, the farmed catfish industry changed the history of the animal, its image, its flesh and bone, its natural environment, and its place in society all by changing—or in an effort to change—its taste. This process moved the catfish from the ranks of a muddy tasting wild fish mainly associated with the poor, to a tasteless, cheap food consumed by all classes and ethnicities. Former cotton planters dug ponds and raised the fish, as researchers at land-grant universities gave the fish a taste and image makeover. Developing a bland meat and an efficient way to grow it presented only half the problem. Workers, predominately black, poor, and female, slaved away in dank, dangerous processing plants. Some struck, despite labor power’s impotence in a globalizing economy. Amid these labor disputes, competition from Vietnamese catfish imports began to trickle in onto the American seafood market. By the 2000s, the “Catfish Wars” had broken out between Asian importers and American farmers. Processors devised quality control measures that washed away the catfish’s distinctive qualities. They had done their work so well, that consumers could tell no difference between fish from around the globe. The farm-raised catfish embodied a culinary, cultural, and technological transformation. My work shows the importance of sensory experiences to southern culture, foodways, African American history, environmental history, and agricultural history.
