Abstract: The exponential increase in the population of Ghana and the need to meet the population’s food security needs while creating job opportunities have necessitated the implementation of the Planting for Food and Jobs (PFJ) initiative by the Government of Ghana (GoG). Using the strengths, weaknesses, opportunities, and threats (SWOT) analytical tool, we SWOT of the PFJ initiative. We further complemented the study with the analytic hierarchy process (AHP) tool to rank the various criteria (factors) identified under the SWOT analysis. The study identified favorable environmental conditions as the highest strength, which recorded 59.3%, followed by agricultural lands availability (21.8%). Inadequate of financial services was identified as the highest weakness (55.8%), followed by over-reliance on climatic conditions (25.9%). High export potential relative to agricultural products in the country was identified as the highest opportunity, which recorded a weight of 50.3%. The One District One Factory (1D1F) initiative came up as the second highest opportunity. Negative ramification of climate change was identified as the main threat to Ghana’s agricultural sector (57.9%), followed by the importation of basic food products (25%).

Abstract: Grain Amaranths are important nutritional vegetables in the world for their grains and leaves. Twelve grain Amaranth accessions were evaluated for their performances using randomized complete block design with 3 replications for 2 years to measure variability and group the accessions. Analysis of Variance and accessions performances revealed significant variability among the grain Amaranths. Phenotypic variances were higher in magnitude than genotypic variance for all the traits studied. High genetic advance was obtained for all the characters except 1000 grain weight (23.61). The genotypic coefficients of variations were lower than the phenotypic coefficient of variations. Heritability ranged from 41.08% for grain yield/plot to 62.18% for plant height at flowering. Grain yield was positive and highly significantly correlated with 1000 grain weight, leaf area but significantly correlated with leaf length and leaf width. The PCA revealed four main components of variations representing 78.06% of the total variability among the 12 grain amaranth accessions. The PCA identified all the 12 traits as strongly correlated with the three principal components. PC1 is well-correlated with Plant height at flowering, Stem girth, Number of leaves, Plant height at maturity, leaf width, leaf length, leaf area and Petiole length. The bi-plot analysis classified the accession NG/AA/03/11/010, NGB 01259, and NGB 0127 as having good leaf yield and desired leaf traits, Accession NHGB/09/108, NG/AO/08/04 and NGB 01261 were grouped as better grain yield with good yield attributes, while accession NGB 01234, NHGB 09/09 and NHAC3 are good dual purpose accessions having good grain and leaf yield.

Abstract: This study explores the causal association between organic and inorganic fertilizer application and vegetable productivity in Ghana. Primary data were obtained from 300 pepper, cabbage and lettuce producers. To correct for self-selection bias and endogeneity, Heckman selection and three-stage least-squares models were estimated. More producers used inorganic fertilizers for pepper, cabbage and lettuce production than those who used organic fertilizers. Vegetable producers applied higher quantities of organic fertilizers (2830 kg) per acre than inorganic fertilizers (880 kg). Organic cabbage and lettuce producers recorded higher productivity than inorganic producers, but inorganic pepper producers had higher productivity than organic producers. However, vegetable producers who applied either organic or inorganic fertilizers, or both, recorded higher productivity than those who did not apply fertilizer. Factors that enhance the application of organic and inorganic fertilizers and vegetable productivity are education, farm size and production for export, land ownership, farmer association membership and perception about fertilizer price. Organic and inorganic fertilizer application improves vegetable productivity, and productivity promotes fertilizer application. Private agencies and government should subsidize fertilizers, improve producers' access to agricultural information, and train producers on productivity-enhancing agronomic practices.

Abstract: Ghana is a typical low-income sub-Saharan African country facing significant sanitation challenges. In Ghana, fresh salads are not part of the normal diet, but have become a common supplement to urban fast food served in streets, canteens and restaurants. In Accra, about 200 000 people consume from such supplements every day. The figure also describes the size of the risk group from contamination, which comprises all income classes including the poor and children. The purpose of this study was to investigate widespread water pollution in urban and peri-urban areas, where 95% of the lettuce consumed in the city is produced. Over 12 months (April 2004-June 2005), lettuce samples from the same production sites in two cities were followed and analyzed along the "farm to fork" pathway for total and faecal coliform (FC) and helminth egg numbers. Questionnaire surveys were conducted among producers, sellers and consumers to quantify lettuce flows to the final risk group. The study identified the farm as the main point of lettuce contamination. Besides the irrigation water, contamination was also attributed to manure application and already contaminated soil. Despite poor sanitary conditions in markets, post-harvest handling and marketing did not further increase the farm-gate contamination levels. To reduce the health risk associated with the consumption of contaminated lettuce; safer farming and irrigation practices are required while the remaining risk could best be addressed where lettuce is prepared for consumption.

Abstract: Nonparametric productivity analyses performed to date show that most developing countries are experiencing relatively rapid technical regress in agriculture. We discuss the plausibility of these results and argue that they stem from the existence of biased technical change and the definition of technology used. We reestimate the Malmquist index for a group of developing countries using a different definition of technology and find that most developing countries in our sample are experiencing positive productivity growth with technical change being the main source of this growth.

Abstract: African indigenous vegetables (AIVs) have been part of the food systems in sub-Saharan Africa for generations. The region is a natural habitat for more than 45,000 species of plants, of which about 1,000 can be eaten as green leafy or fruit vegetables that happen to be the mainstay of traditional diets. During the colonial era, adventurers and slavers sailing in Africa introduced exotic plants such as maize, cassava and beans and, later, commercial crops such as sugarcane, cocoa, coffee and cotton, which began contributing more to life. Farmers integrated these crops into their age-old livelihood strategies at the expense of traditional subsistence crops. AIVs were almost entirely neglected and considered ‘poor people's' plants. To reverse the trend, FARM-Africa and its partners reintroduced AIVs which are now forming part of families’ diets as well as becoming a source of income for smallholder farmers in Arumeru, Tanzania and Kiambu, Kenya. AIVs are robust and productive, and thus well suited to feeding...
