An estimation of the effects of food aid on domestic food production and commercial food imports in Zimbabwe

Chiweta, Chenai January 2012 (has links)
Food aid and domestic food production capacities in Zimbabwe have been compromised by the poor performance in the country’s agricultural sector, which has necessitated an increase in and a continual need for humanitarian assistance over the past decade. The country’s commercial cereal food import capacity has not been an exception as it has also been greatly affected by the poor performance of the agricultural sector and the shortage of foreign currency that hit the country in the past few years. Secondary data on food aid, commercial cereal imports and cereal food production was obtained from World Food Programme (WFP), Food and Agriculture Organisation (FAO), the Grain Marketing Board (GMB) of Zimbabwe and from Zimbabwe Statistics (ZimSTATS) databases. This time series data was then analysed in the Vector Autoregression (VAR) analysis. Trends observed in the time series data reveal that commercial cereal food imports and cereal food aid inflows to Zimbabwe had been increasing between 1988 and 2008. Domestic cereal food production levels however were observed to have been declining within the same period. The restricted VAR model which was specified to investigate the short and long term effects of food aid on food production and on commercial food imports in the country revealed a low statistically significant positive relationship between domestic food production and food aid volumes. Results from the model also indicated a negative relationship between commercial food imports and food aid volumes. This means that as food aid volumes to Zimbabwe increase, the volume of commercial cereal food imported into Zimbabwe falls. This result therefore suggests that food aid in the country had a displacement effect on commercial cereal food imports in the short term. The results of the Granger causality test and the estimation of the Impulse Response Functions also helped to confirm and reinforce these findings from the vector error correction model. The conclusions drawn from the study were that the responsiveness of domestic food supply, that is, cereal production, to food aid inflows in the short term has been elastic. That is to say, an increase in food aid inflows would influence an increase in the level of domestic food production in the short term. However, in the long term, findings confirm that food aid does indeed discourage domestic food production in the country. Also, for the relationship between food aid and commercial food imports, it can be concluded from the study findings that food aid in the short term has caused a reduction in commercial food imports whereas in the long term, food aid inflows have actually stimulated the commercial food import capacity. In recommendation, the Government of Zimbabwe, the private and public institutions as well as the Non-Governmental Organisations should partner and work together in defining the criteria for vulnerability assessment, food aid targeting and distribution, and in the implementation of strategies for ensuring national food availability. Such partnerships would help in ensuring the sustainability of food aid and food security in Zimbabwe, which is the main goal.

Biological Warfare Against Crops

Whitby, Simon M. January 2001 (has links)
Until now little attention has been paid to the development of military capabilities designed to target food crops with biological warfare agents. This book represents the first substantive study of state-run activities in this field. It shows that all biological warfare programmes have included a component concerned with the development of anti-crop biological warfare agents and munitions. Current concern over the proliferation of biological weapons is placed in the context of the initiative to strengthen the Biological and Toxin Weapons Convention. The book concludes by arguing that the risks posed by this form of warfare can be minimised, but that this would depend largely on the effective and efficient implementation of regimes concerning the peaceful use and control of plant pathogens that pose a risk to human health and the environment.

A case study of the impact of irrigation on household food security in two villages in Chingale, Malawi

January 2008 (has links)
This case study investigated the impact of irrigation on household food security at Ibu and Kalizinje villages in Chingale, Malawi. The aim of the study was to investigate whether irrigation improved household food security. The study was qualitative in nature. Fifty-eight farmers and three World Vision field staff participated in the study. Group discussions with participatory techniques and in-depth interviews were used to collect data. Data were analysed qualitatively using matrix/logical analysis. Irrigation improved irrigating farmers’ household food security through an increase in production and income levels. Irrigating farmers were better off in terms of crop production and income levels than non-irrigating farmers. Irrigating farmers planted irrigated maize two to three times a year, while non-irrigating farmers planted rain-fed maize only once a year. In terms of income levels, irrigating farmers produced more food than households required, and sold surpluses. Most irrigating farmers began cash cropping after the introduction of irrigation and also earned higher incomes, as irrigation enabled production of crops during lean periods and enabled them to sell surpluses at higher prices. Irrigation did not improve crop diversification. Non-irrigating farmers diversified crops more than irrigating farmers by planting groundnuts and sweet potatoes. Income from irrigating farmers did not increase dietary diversity and the acquisition of assets for irrigating farmers. Few farmers consumed a variety of foods and few acquired assets with the income derived from irrigation. Nevertheless, irrigation has the potential to smooth production cycles and provide food and income during seasons when food and income would be low. In addition, the study revealed the following as problems faced by farmers: constraining size of small diesel pumps, pump breakdown at Kalizinje, floods, pests and diseases, storage problems, lack of market places and poor roads, small land sizes, and expensive farm inputs. / Thesis (M.Sc..)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Socio-economic contribution of community food gardens to the livelihoods of rural households in Lepelle-Nkumpi local municipality of Limpopo province, South Africa

Malahlela, Nkele Dorcus January 2014 (has links)
Community food gardens are regarded as a means through which rural households can improve their livelihoods. This study explores the contribution of community food gardens (CFG) to livelihoods in the Lepelle-Nkumpi local municipality in the Limpopo province. The objectives of this study are, firstly to explore the reason behind CFG participation and the reasons behind the participating possibility. Secondly, the study seeks to identify the socio-economic factors influencing the participation of households in CFG and lastly to determine the influence of CFG and other socio-economic variables on household food security status (HFSS). Descriptive statistical analysis was used to describe the socio-economic characteristics and the reasons behind CFG participation and the reasons behind the participating possibility. The binary logistic regression model was used to analyse the determinants of household participation in community food gardens as well as the contribution of CFG to HFSS on Statistical Package for Social Science (SPSS) software version 21. Through a structured questionnaire, data was collected from a sample of 180 households which was obtained using multistage sampling. Descriptive results on the characteristics of sampled households revealed that there are high levels of food security in the area with 70% being food secure of which around 42.2% are CFG participants and 30% are food insecure. Furthermore the descriptive statistical analysis indicated that participation of households in CFG is mainly to obtain a source of food among the CFG participants and to generate income amongst the non-participants. On the basis of descriptive analysis, this study concludes that source of food and income generation respectively are the main reasons behind CFG participation and the possibilities of becoming a participant. Therefore the study accepts the research hypothesis stating that “There are social and economic reasons behind household participation and the possibilities of participating in CFG”. Binary results for the determinants of CFG participation revealed that socio-economic variables such as household size, farm income, household monthly income, land size, household perception, marital status, agricultural training and homestead gardening significantly influence household decisions to participate in CFG. This is an implication that socio-economic variables tested in this study are significantly influential to the household decision to participate in CFG, leading to the acceptance of the first hypothesis which states that “Socioeconomic factors determine the community food garden ownership or participation”. The results of the contribution made by CFG to HFSS showed that socioeconomic variables such as gender, age, household size, farm income, educational level, household monthly income, marital status, information access, formal employment status and CFG involvement significantly affect household food security status in the study area. The result indicates a positive contribution to HFSS and implies that socio-economic variables tested in this study have a significant influence on HFSS, leading to the acceptance of the second hypothesis which states that “Community food gardens have a positive effect on food security status of household in Lepelle-Nkumpi Local Municipality Limpopo province.” Therefore it is relevant to concluded that in the area of Lepelle-Nkumpi local municipality, social economic factors plays a vital role in the participation of households in CFG as well as improving the state household food security status.

Home gardens, cultivated plant diversity, and exchange of planting material in the Pacaya-Samiria National Reserve area, northeastern Peruvian Amazon

Lerch, Natalie Corinna. January 1999 (has links)
Traditional peoples are often described as "stewards of agricultural diversity", yet little research has been conducted on the determinants of agrodiversity. This thesis focuses on agrodiversity and how peasant farmers build and maintain cultivated plant diversity in home gardens found in three distinct traditional communities along the Maranon river in the Peruvian Amazon---an upland mixed agricultural village, a lowland agricultural village, and a lowland fishing village. Data were gathered through household surveys (n = 192) and in-depth interviews (n = 112). Substantial variation in cultivated plant diversity was found among and within villages. Residents with the highest home garden agrodiversity tend to be among the wealthier households, and are more likely to have both established their own garden, and tended it for longer periods. Complex planting material exchange networks underlie the establishment and maintenance of home garden agrodiversity. The results underscore the importance of studying local variations in agricultural diversity, and exchange networks that bring agricultural planting stock to peasant farmers.
