    Keywords: Home garden, HIV and AIDS, dietary diversity, plant species diversity, coping strategy index, food security, Ghana.

    The aim of this thesis was to explore how rural households with HIV and AIDS in Ghana are employing home garden management strategies to enhance food and nutrition security and also to examine the seasonal dimension of coping with food insecurity in these rural households through documentation of the frequency and severity of the food–related coping behaviours adopted during periods of peak seasonal food shortages. In Sub-Saharan Africa, home garden cultivation is considered to be a potential strategy for rural households with HIV and AIDS to cope with labour constraints and to improve food and nutrition security. However, existing research that has addressed the relationship between HIV and AIDS, home gardens and food security focused on predictions; there is severe dearth of empirical evidence. Qualitative and quantitative research methodologies were used in this study. Data collection methods included focus group discussions, interviews with key informants, a questionnaire-based survey, in-depth interviews in case studies and participant observations. A 24-hour qualitative dietary recall was used to assess dietary intake of households studied and the Coping Strategy Index was used to assess the severity of household food-related coping behaviours. Data on biophysical aspects of the home gardens was obtained through a home garden survey. The results showed that when labour constraint reduced field cultivation in rural households with HIV and AIDS, labour input in home garden significantly increased; rural households did not cultivate a greater diversity of plant species in home gardens, but rather relatively more food items of the essential food groups were consumed from home gardens. This contributed significantly to dietary diversity. Uncovering the effect of the interaction between household HIV status and gender of the household head on home garden biodiversity indicated that female-headed households with HIV and AIDS depended more on home gardens than their counterparts without HIV and AIDS in producing crops for sustenance and dietary diversity. Exploring the biodiversity in home gardens of rural households with HIV and AIDS when home garden cultivation is also meant to generate cash income revealed that rural households experiencing HIV and AIDS illness in cultivating commerce-oriented home gardens cultivated a dual purpose home garden that provided cash income and also supplied subsistence food. Assessing the frequency and severity of the food-related coping behaviours adopted by farm households with HIV and AIDS during the post-harvest period and in the lean season showed that farm households with HIV and AIDS were more vulnerable to food insecurity in both the post-harvest and lean season; this vulnerability was also reflected in their poverty, family care burdens (larger number of dependents and ill persons), lower education level and meagre income earning opportunity. It is essential that concerted efforts are made to improve the general well-being of farm households with HIV and AIDS by empowering rural households with HIV and AIDS in terms of capacity building, access to livelihood assets and access to finance.


     


     

    Bodemverontreiniging en de opname van lood door moestuingewassen : risico’s van lood door bodemverontreiniging

    Lood uit bodemverontreinigingen wordt opgenomen door moestuingewassen die daarop worden geteeld. Deze gewassen kunnen een gezondheidsrisico vormen als zij worden geconsumeerd. Uit deze studie van het RIVM en Alterra blijkt dat bij hoge concentraties lood in de bodem de opname minder wordt. Hierdoor bevatten de gewassen op deze bodems minder van dit metaal dan aanvankelijk werd gedacht.
    Locatiespecifiek onderzoek naar de risico's van lood in moestuinen : gehalten aan lood in de bodem en moestuingewassen in het volkstuincomplex 'Aan het Meer' te Heerenveen

    Locatiespecifiek onderzoek naar de invloed van verhoogde gehalten aan lood in de bodem in het Volkstuincomplex ‘aan het Meer’ te Heerenveen toont aan dat de gehalten in de gewassen niet leiden tot onacceptabele blootstelling. De gemeten gehalten in belangrijke groenten in moestuinen (aardappel, sla, andijvie, bonen) zijn normaal en liggen een factor 3 tot 10 lager dan de berekende waarden met C-Soil. Dit betekent dat de risico-index op basis van gemeten gehalten varieert van 0.03 tot 0.21 voor levenslange blootstelling en maximaal 0.55 voor kinderen terwijl de standaardbeoordeling leidt tot risico-indexen hoger dan 1. Op grond van de metingen blijkt dat het gebruik als moestuin daarmee geen enkel risico oplevert. Geadviseerd wordt de groenten wel goed te wassen en de pH van de bodem op een niveau rond 5.5 tot 6 te houden of te brengen door (extra) bekalking.
    A journey without maps: towards sustainable subsistence agriculture in South Africa

    Participatory technology development within the subsistence-farming sector in South Africa is receiving increasing attention. Linked to this is an interest in sustainable development, particularly for agricultural interventions. Ecological approaches to agriculture have largely been considered unable to provide a route for income generation. However, some promising examples of sustainable small-scale farming systems can be found in South Africa. The main aim of this thesis was to identify factors within these development programmes that led to sustainable technology development in the context of subsistence farmers’ livelihoods. This objective was achieved through exploring practically, the concepts derived from the sustainability paradigm. To be sustainable, a farming system should be biologically, technically and socially feasible and viable at farm level, within a positive and enhancing external environment. Sustainability ultimately concerns the relationships between all elements of the farming system and for this reason researching sustainability in agriculture requires a multi-level, multi-aspect and multi-actor approach. Sustainability was explored in three case studies in this thesis and at a number of levels: field level; farm and district level, including organizational interaction. Different aspects were researched that included agricultural technologies, household livelihoods and organizational development. The various actors involved in the technology-development process examined in the three case studies included farmers, change-agents, researchers and local traditional authorities. Interactions at all three levels influenced and contributed to the overall sustainability of the development intervention and this research supports the widely demonstrated conclusion that the challenges faced by agriculture will not readily be solved by technological interventions at the field level alone. The factors at each of the levels that contributed to the sustainability of the develop projects are presented and the lessons learned from the three case studies are also given.

    Vanwege het vóórkomen van verhoogde gehalten aan lood, zink en koper in tuinen in Den Bommel is in opdracht van de provincie Zuid Holland een inventariserend onderzoek gedaan naar de kwaliteit van bodem, en gewassen (sla en aardappel) geteeld in een van de tuinen. Ondanks de sterk verhoogde loodgehalten in de bodem die in enkele gevallen de interventiewaarde overschrijden, worden geen gewasnormen (huidige warenwet voor Pb en Cd) in de onderzochte groenten overschreden. Dit is het gevolg van de lage beschikbaarheid van de genoemde metalen als gevolg van een hoge bodem pH en het bodemtype. De berekende blootstelling met C-Soil toont aan dat de levenslange blootstelling bij gebruik als moestuin niet tot een onaanvaardbaar risico leidt. Daarbij is zowel gebruik gemaakt van de huidige standaard versie van SUS (huidig beleid) en een herziene versie van C-soil waarin nieuwe inzichten op het gebied van blootstelling en beschikbaarheid van lood zijn meegenomen.
