Innovative agricultural extension value chain-based models for smallholder African farmers

The value chain extension strategy of Sasakawa Africa Association focuses on improving the capacity of national agricultural extension systems and follows various thematic areas along the value chain to address key challenges accountable for low income households and poverty in Africa. Farmer learning platform is a model designed to increase crop productivity and encompasses demonstration plots where technological packages demonstrated significantly outperformed other technology plots in crop productivity and average profit margins. Enterprise-oriented production, postharvest and trading centers are value adding models designed to improve the effectiveness of extension and adoption of postharvest and agricultural processing technologies by producers. The use of the above along with necessary capacity building has facilitated the development of profitable business linkages of smallholder farmers with financial institutions and reliable market opportunities. The community association trader-trainer model is a market-oriented business approach applied in combination with other extension models. In 2018, 297 community-based commodity association trader-trainers were mobilized and capacitated to improve farmer group dynamics and developed collective input and output access and cluster aggregation centers at community level where various agricultural produces were mobilized and collectively aggregated, and valued at about 3.9 million USD. The supervised enterprise project model is an innovative agricultural extension model developed along with above models for capacity development of extension agents and transfer of technologies to smallholder farmers. Over 6000 supervised enterprise projects have been introduced into 27 universities in 12 African countries for training front-line extension officers and extension delivery to farming communities.

In Benin, the shea sector is one of the most promoted sectors in government’s attempt to diversify sources of farm income. The objective of this study is to evaluate the impact of the adoption of the semi-mechanized shea processing on the income of rural women in northern Benin. In total, a random sample of 200 women processing shea was investigated. A probit model was firstly run to analyze the factors determining the adoption of the semi-mechanization. Then, a multiple regression model was used to assess the impact of adoption on women's income. The results highlighted that, the adoption of semi-mechanization was determined by availability of electricity, availability of a market, contact with extension services and shea processing as main activity for woman. Moreover, the adoption of semi-mechanization has induced a positive and significant increase of rural women’s income up to 103 914 Francs CFA. As a result, it is important that agricultural policy reinforce the promotion of modern agricultural processing technologies to improve the added value and to reduce poverty in rural areas. As well, electricity and market access, women’s level of education and contact with extension need to be improved. Key words: Adoption, impact, shea processing, semi-mechanization, income, Benin.

Bacillus cereus SS28 isolated from budu, a fermented fish product from West Sumatra, produced antimicrobial compound that had broad spectrum of inhibition against five microorganisms (Escherichia coli, Staphylococcus aureus, Salmonella thypi, Bacillus subtilis, and Listeria monocytogenes). The aims of this research are characterization of Bacillus cereus SS28 antimicrobial activity and observation of its effect to the cellular morphology of Staphylococcus aureus with electron microscope. Antimicrobial compound produced by Bacillus cereus SS28 was stable at pH range between 2 and 11 and to heating at 121 °C for 15 min. Maximum antimicrobial activity was expressed at pH 2-3 and 70 °C for 45 min. The activity remained after 15 min exposure to UV light. The main changes observed under SEM and TEM were the alteration of Staphylococcus aureus structural cell membrane 48 h after exposure to the antimicrobial compound from Bacillus cereus SS28.

Exergy Analysis and Experimental Study of a Vehicle-Mounted Heat Pump–Assisted Fluidization Drying System Driven by a Diesel Generator

In light of present development of Chinese agricultural processing technology, a vehicle-mounted grain drying system driven by a diesel generator has been developed to work interregionally with the existing combine harvester to harvest and dry grain simultaneously. A horizontal multichamber fluidized bed was chosen as the drying chamber, and a vapor compression heat pump (R134a as refrigerant) supplies heat for this system. The latent heat of steam discharged from the fluidized bed's forepart is recovered by the heat pump evaporator, and ambient air is blown into the rear part to recover sensible heat from the postdrying grain. Heat exchangers are installed along the air duct to recover the waste heat from the cooling water and flue gas in the diesel generator, to increase the primary energy ratio (PER). The exergy efficiency of the semiclosed heat pump was 29.2% based on the mathematical model. Performance tests of the drying equipment showed that the actual PER of the drying system was 1.19, the coefficient of performance (COP) of the heat pump was 4.38, the actual specific diesel consumption was 0.081 (kg diesel)/(kg water), and the designed targets were mostly achieved.

Intermediate Agricultural Processing Technologies for Cereal Crops in South Africa

ABSTRACT A comparative evaluation of the performance of a tractorpowered maize sheller and shelling with tractor wheels, electrically and diesel-operated sorghum milling machines with traditional maize shelling and sorghum milling techniques was conducted at Vergelegen rural community in the Northern Province of South Africa. Maize shellers and the traditional shelling techniques were evaluated in terms of shelling efficiency, grain output and grain damage, while the sorghum milling machines and the traditional techniques were evaluated in terms of flour output, losses and quality of output. The performance of these intermediate processing technologies for shelling and milling operations were compared with traditional processing techniques. Shelling of maize with tractor wheels incurred the highest percentage of grain damage. The difference in shelling with intermediate technologies and traditional techniques has significant effects on grain damage, grain output and shelling efficiency. A higher flour output from sorghum was obtained with new milling technologies than with traditional milling technique. The different milling methods have significant effects on the degree of fineness of flour for particle size greater than 1000 micrometer and less than 150 micrometer.

Impact of Indonesian Commitments and Other Policy Options Under the WTO on the Marcroeconomy, Agriculture and Household Income

This paper attempted to carry out an analysis of the actual impact of Indonesia's commitments including other policy options under the WTO. Using a computable general equilibrium (CGE) model, the study analyzed three policy options involving tariff reduction as follows: (1) The government adopts the existing reduction in applied tariff on agricultural and non agricultural sectors, (2) The government adopts only 50% of the existing tariff reduction, and (3) The government goes to full liberalization by removing tariff in agricultural and non-agricultural sectors, that is, tariff is set at zero level. Results showed that the tariff reduction generally caused an increase in Gross Domestic Product (GDP) and aggregate output. However, some macroeconomic variables such as terms of trade, export price index, trade balance, and tariff revenues have been adversely affected. Likewise, output of some sectors in agriculture declined due to tariff reduction including the horticulture industry (fruits, vegetables), non-food agriculture (other crops), and beverage crops (rubber, sugarcane, coconut, oil palm, tobacco, coffee, tea, clove, fibre, and other estate crops). The tariff cut has also reduced the nominal household income. However, household consumption still increased due to lower prices following tariff reduction. Adoption of only 50% of the existing tariff reduction has less impact on the macroeconomy, agriculture and income of different household groups. In contrast, maintaining the present commitment on tariff reduction would have greater impact. The greatest impact would be when the government reduces applied tariff to zero on both sectors. This study suggests that the government should provide strong support to facilitate the development of the horticulture industry, non-food agriculture, and beverage crops sectors. Tariff reduction on these sectors should be undertaken gradually to minimize the social cost of adjustment. The government should provide compensation to household groups adversely affected by tariff reduction through either an increase in government transfers or a decrease in the personal income tax rate or both. Since these measures will affect the fiscal position of the country, the government should improve the competitiveness of agricultural export industries with high potentials for market expansion through the development of agricultural processing technology.

Analyzing the Competitiveness of Indonesian Agricultural Commodities Under WTO Commitments

This paper provides an ex post analysis of the competitiveness of Indonesian agricultural commodities during the implementation of the WTO commitments. Using the COMTRADE databases according to the Standard International Trade Classification revision 2 (SITC rev 2) that was published by World Bank, the study revealed that Indonesia's exports to world market in 1985-1990 and 1990-1995 period consisted mainly of coffee, tea, cocoa, spices, and manufacturing products (SITC 07). They are classified as Declining Stars, respectively. These commodities continue to decline under WTO commitments (1995-2000 periods) and therefore the section qualifies as a Retreat. Similarly, Section 03 (fish, crustaceans and mollusks and preparations thereof) was classified as Rising Stars in the first period (1985-1990) and Declining Stars in the second period (1990-1995). Other commodities such as miscellaneous edible products and preparation (SITC 09) also changed from Rising Stars in the first period and the second period into Retreats, followed by those of SITC 05 (vegetables and fruit) which was classified from Declining Stars to Retreat. Under WTO commitments (1995-2000), there are no items in that could be classified as a Rising Star. All commodities were classified as Declining Stars (SITC 00, 02, 04 and 09) and Retreats (SITC 01, 03, 05, 06, 07 and 08). Thus, most of agricultural commodities classified as Stagnant Commodities, even in the third period in which commodities that were classified as Dynamic Commodities were zero. These indicated that Indonesian agricultural commodities have decreased in terms of its competitiveness under WTO commitments. Thus, government should provide strong support to facilitate the development of agricultural sector. Indonesia may consider some facilitation role for the government such as the establishment and improvement of facilities and developing mechanism for attracting domestic and foreign investments in agricultural sector. In addition, government should improve the competitiveness of agricultural export industries with high potentials for market expansion through the development of agricultural processing technology.
