- Description: Food constitutes a key component of a number of fundamental welfare dimensions, such as food security, nutrition and health. It makes up the largest share of total household expenditure in low-income countries, accounting on average for about 50% of the households’ budgets. Most demand analysis use existing models, but this study applied a new model – SEDS to analyse food demand among farming households in South West Nigeria. A multi-stage sampling technique was employed study to select 342 respondents. Primary data was collected through the use of a structured questionnaire. Data collected include information on a number of different food groups consumed by households, socioeconomic characteristics, demographic factors and income. The analytical techniques used were descriptive analysis and the Substitution Elasticity Demand System (SEDS). The result of SEDS shows that own price elasticities were less than 1 except for root and tuber, and fats and oil. It was found that cereals, legumes, fruit and vegetables and animal protein were price inelastic, i.e. necessities, and roots and tubers and fats and oils were price elastic, i.e. luxury goods.

- Description: An alarming four billion individuals worldwide grapple with acute water scarcity. Notably, South Africa, nestled amongst the world's most parched lands, suffers from severe freshwater limitations, ranking 30th in scarcity indices. Introduced in 2003, the" water footprint" framework offers a valuable technique for measuring water utilization in production systems. The WF is composed of three colors: green, blue, and grey. The present study aimed to investigate the water footprint and economic productivity of potato production in South Africa. Data on potato production, price, and weather data from 2006 to 2015 were obtained from the Potatoes South Africa (PSA), Department of Water and Sanitation (DWS), Department of Agriculture, Forestry and Fisheries, and Food and Agriculture Organization (FAO) databases. Analysis of staple water use, evapotranspiration, and irrigation schemes for crop production was carried out using CROPWAT 8.0 software as well as physical, land, and economic water productivities. Across South African provinces, the water footprint of potato production-encompassing green, blue, and grey components-outstrips global averages, exhibiting notable provincial discrepancies. The result shows that there is a need for more efficient water use across the provinces. PWP was highest in Northern Cape (3.08 t/m 3) and lowest in Gauteng (1.99 t/m 3). EWP was highest in the Northern Cape (1.0) and lowest in Gauteng (0.65 US $/m 3) depicting the high cost of water use per m 3 in potato production. ELP, however, was highest in the North West and lowest in the Free State. The scenario could be improved upon by efficient irrigation water use and the application of a minimum level of fertilizer in a bid to ameliorate blue and grey water.

- Description: The dietary practices of households have significant repercussions on the quality of life of its members. Dietary practice generally shows the types and variety of food intake and is extremely reliant on the socio-demographic characteristics. Dietary diversity has been positively associated with the four pillars of food security and all dietary guidelines propose consuming a large variety of foods, across and within major food groups. This paper focuses on the influence of socioeconomic factors on household-level food consumption diversity (FCD) in Nigeria. Since the majority of Nigerians (70 per cent) live in rural areas, an analysis of the food and nutrition security status of rural dwellers will provide a clear picture of what needs to be done to assure food security. A multistage sampling technique was employed for the selection of respondents from a random sample of households proportionate to the size of three states in the south-western agricultural zone of Nigeria, and primary data were collected using an interview guide. The analytical tools used were descriptive statistics, inferential statistics, mean food consumption diversity index and multinomial logit regression model.
