This open access book seeks effective strategy to realize a rice Green Revolution in sub-Saharan Africa based on more than ten years of research team’s inquiries into determinants and consequences of new technology adoption in rice farming in seven countries in this region. Rigorous statistical analyses are carried out by using valuable household data of rice farmers. The book is actually sequel to the two earlier books on the same subject published by Springer and edited by K. Otsuka and D.F. Larson, An African Green Revolution published in 2013 and In Pursuit of an African Green Revolution in 2016. The main message of the first book was that rice is the most promising cereal crop in SSA because of the high transferability of Asian rice technology, whereas that of the second book was that rice cultivation training programs are effective in significantly increasing rice yield in SSA. This third book has wider coverage in terms of topics, study periods, and study sites. It continues to show the significant impacts of rice cultivation training on productivity and newly demonstrates the high sustainability of the productivity impact of the training and the existence of spillover effects from trainees to other farmers by using panel data. We newly assess the important role of mechanization in intensification of rice farming, high returns to large-scale irrigation schemes, and the critical role of rice millers in improving the quality of milled rice. Based on these studies, this book provides clear pathways toward full-fledged Green Revolution in rice farming in sub-Saharan Africa.

Ghana’s aquaculture sector is among the recent success stories of fast-growing agricultural value chains in Africa south of the Sahara. The sector has also shown its vulnerability, with the infectious spleen and kidney necrosis virus spreading through tilapia farms in Lake Volta in late 2018. The global COVID-19 human pandemic reached Ghana in early 2020, affecting the sector directly and indirectly. Using a value chain approach, phone interviews were conducted with 369 small-scale fish farmers in six major producing regions, with 12 other value chain actors, and with 423 consumers in the capital, Accra, to assess the impact of COVID-19 on the sector. All value chain actors interviewed reported being affected directly by COVID-19 related restrictions on movement and indirectly by reduced demand for tilapia because of closures in the tourism and hospitality industries, important consumers of fresh tilapia. The crisis has reduced incomes for most actors along the aquaculture value chain and is anticipated to reduce future production. Most fish farmers surveyed were affected by disruptions in input and output markets. Two-thirds of the sample farmers were growing fish and 6 percent were harvesting when the COVID-19 crisis hit. Fifty-four percent of those growing fish experienced difficulties in accessing inputs – mainly fish feeds. Of those harvesting during the crisis, most experienced difficulty in selling their fish mainly because of low demand from buyers, lower tilapia prices, and higher transportation costs than before COVID-19. Income losses among fish farmers, including from other sources, such as crop farming, wage employment, and other own businesses, limits the funds that they have available to finance fish farming operations or to invest in future production capacity. Likewise, reduced incomes and purchasing power of consumers is causing a sharp decline in demand for fish.

This study provides an assessment of changes in household income, livelihood sources, food consumption, and diet quality during the first months of the COVID-19 crisis in a sample of households drawn from both urban and rural areas in Ghana. Phone surveys were conducted in June 2020 with 423 urban consumers in Accra and with 369 small-scale crop and fish farmers in rural areas in six regions in middle and southern Ghana. Data was disaggregated by asset quintiles for both the urban and the rural samples. Reduction in incomes were reported by 83 percent of urban households in Accra, mainly due to business closures and lower sales from their trading enterprises. Most households, however, are showing resilience in terms of food consumption, with a majority of urban consumers surveyed maintaining their pre-COVID-19 level of food consumption; only 9 percent of urban consumers reported reductions in food consumption to cope with income loss due to COVID-19. For the respondents in the rural areas in middle and southern Ghana, 76 percent reported income loss, and all reported that their livelihoods had been affected. Thirty-four percent of 2020 minor season crop farmers experienced difficulty in selling their produce, and 43 percent of all sample crop farmers anticipated difficulties in accessing inputs in the 2020 major season, mainly fertilizers and agrochemicals. Of those growing fish, 53 percent experienced difficulty in accessing inputs, mainly feeds; 60 percent reported increased input prices; and 64 percent of those harvesting from March to June 2020 experienced difficulties in selling their fish because of lower demand, lower tilapia prices, and higher transportation costs. Despite farm and nonfarm income losses, a majority of households in the rural sample reported maintaining previous levels of diet diversity and food consumption - only 11 percent reported reducing their food consumption to cope with income loss. Several months into the COVID-19 crisis in Ghana, households in both rural and urban areas showed some resilience in terms of their agricultural production and food consumption. Regular monitoring is needed, however, especially if household savings start to dry up and coping mechanisms become more restrictive.

Developing sustainable organic agriculture and resilient agribusiness sector is fundamental, keeping in mind the value of the opportunity presented by the growing demand for healthy and safe food globally, with the expectation for the global population to reach 9.8 billion by 2050, and 11 billion by 2100. Lately, the main threats in Europe, and worldwide, are the increasingly dynamic climate change and economic factors related to currency fluctuations. While the current environmental policy provides several mechanisms to support agribusinesses in mitigating organic food for daily increasing human population and stability of the currency, it does not contemplate the relative readiness of individuals and businesses to act correctly. Organic farming is the practice that relies more on using sustainable methods to cultivate crops and produce food animals, avoiding chemicals and dietary synthetic drug inputs that do not belong to the natural ecosystem. Organic agriculture can also contribute to meaningful socioeconomic, ecologically sustainable development, and significantly in the development of the agribusiness sector, especially in developing countries.

Ghana has a long history of intervening in food markets to balance consumers’ expectations of low and stable food prices, farmers’ demands for high farmgate prices, and traders’ demand for predictability in seasonal price patterns. However, government interventions may also alter the behavior of markets and alter incentives or risks for all market actors. The Planting for Food and Jobs (PFJ) initiative, launched in 2017, signaled a renewed commitment from government to agriculture and is Ghana’s flagship strategy for boosting smallholder production, strengthening market linkages, and developing value chains. Given this significant policy shift, we examine agricultural commodity price patterns before and after 2017 to identify potential structural shifts in price behavior in maize, tomato, and onion markets, three key sectors targeted by PFJ. Results show maize and tomato prices drop below their long-term trend under PFJ, but not onion prices. Tomato and onion prices exhibit smaller seasonal price variations. These results are indicative of a structural shift in food markets, although further analysis is required to conclusively attribute these changes to PFJ.
