The future additional rice demand will mainly come from the population growth in Africa and Asia. The production growth during the past led by growth in yield has helped in meeting rice demand around the globe. However, Africa continues to lag far behind other continents in achieving the desired level of yield. Additional research efforts are needed in all continents for the production of varieties with higher yield potential and desired grain quality with more emphasis on the African continent. The global demand for rice will be about 584 million tons or less towards 2050. With positive technological developments in the rice research arena, the shape of rice agriculture will change towards 2050. Asia may lose about 5 million ha and Africa gain about 10 million ha of rice land by 2050.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"164 - 172"},"PeriodicalIF":3.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43240536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the introduction of Vitamin A rich varieties, efforts were made to commercialize the crop. This study assessed the effects of this commercialization on women producers. Findings indicate that though women devoted more land to sweetpotato, men got higher yields, sold more and obtained better prices. Nonetheless, women dominated the roots value chain and increased their participation in markets. The more lucrative sweetpotato vine chain was dominated by men (75% men), as the resources and skills required to engage in this activity were a significant challenge for women. Women perceived that sweetpotato commercialization increased their ability to make production decisions, though it has not resulted in any changes in ownership of resources. Women and men both noted a subtle change in norms. Men for example perceived that their ability to make decisions had reduced, while women noted that they had taken on more leadership positions locally. These changes might be attributed to the role played by project implementors who encouraged men to allow their spouses to engage more in commercial activities. Whilst women faced challenges related to literacy, market entry and access to resources, they valued the experience obtained in improving their entrepreneurial skills. Future commercialization initiatives should work on linking women to business services and building stronger farmer-processer linkages. Efforts to sensitize men about the benefits of women's engagement in business showed some impact and should be included in further work on crop commercialization.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"349 - 358"},"PeriodicalIF":3.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47994682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An online survey was used to gather information about farmers selection and use of abattoirs, and a telephone survey of abattoir owners and managers complemented the farmer survey. Of the 300 respondents, 185 used abattoirs for private kill retail (PKR) services. 121 of these PKR farmers (65.4%) reported their PKR business as “essential” “or “very important” to the viability of their farm business. Seventy-five (41%) had no alternative abattoir, 21 of these 75 would have to close their PKR business if the abattoir they currently used closed, 22.7% would reduce their grassland area, releasing greenhouse gases, and 30% would stop farming native breeds, reducing the gene pool and conservation grazing environmental management options. 110 PKR farmers did have a viable alternative abattoir, but using it would increase livestock journeys, increasing greenhouse gas emissions and making it more likely farmers would need to use commercial rather than farm transport, further jeopardising animal welfare and biosecurity. Therefore, the continuing closure of private kill services threatens core government policy objectives. However, private kill services could be supported by government grant schemes, resolving confusion regarding food labelling, and reducing small abattoir costs by introducing “de minimis” derogation – as currently used on some Channel Island and mainland Europe abattoirs.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"323 - 333"},"PeriodicalIF":3.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49641538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the seed exchange network structure, disease surveillance risk, and gender contribution in Burundi, under two banana disease risk scenarios. Two sites where banana bunchy top disease (BBTD) is endemic in Cibitoke Province were compared with a site free of the disease in Gitega Province. All sites had formal seed interventions using community nurseries. A quantitative survey on seed sharing was done followed by a qualitative evaluation through focus group discussions. Banana seed sourcing options were fewer in the disease-free site, which also had higher cultivar diversity. Most farmers sourced seed informally within a three-kilometer radius. Seed sharing within and between villages was based on social and family linkages, especially for women. The interaction between the formal system and informal seed exchange was more active where new cultivars, or better seed quality was expected. The BBTD endemic region had lower seed quality assessment stringency. Farmers used both direct mother plant assessment and seed source reputation in seed evaluation. The formal banana seed systems are sources of new varieties, and trusted for clean seed but the informal system was still used as a main source of seed, especially local cultivars. Assessing disease surveillance scenarios shows women in a weaker position for healthy seed acquisition. Identifying the roles of individuals in seed systems can support decision processes for seed interventions in vegetatively propagated crops.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"334 - 348"},"PeriodicalIF":3.0,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42981966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its slow onset and recurrence threaten livelihoods dependent on agriculture. Responses to drought have mostly been ex-post impact management with little ex-ante resilience building in vulnerable areas. Implementation of ex-ante strategies has been severely challenged by lack of skilled human capital to predict and respond timely and effectively to the impacts of drought, particularly in smallholder farming areas. Human capital development, should therefore, be prioritised as a key drought management strategy. In this regard, it is important to determine farmers and agricultural professionals’ current and future needs for capacity development in drought management. This is important given that drought is projected to increase risks and introduce new ones with far more devastating impacts on agriculture. The current review outlines the implications of drought on agricultural skills in South Africa and the way forward.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"293 - 302"},"PeriodicalIF":3.0,"publicationDate":"2022-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45997681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper unravels these interactions using the data collected from 1053 migrant households in the mountains of Nepal. The result shows that household size positively and the number of 17–60-year-old household members negatively influence maize yield. Remittance income and raising farm animals enhanced maize yield. Geography, especially maize farming in the mountains, showed a reduction (25.6%) in yield. The migrants’ wives stated less maize yield (5%) compared to the other household members. In addition to these contextual factors, women's increased participation in the household chores, rearing and caring of farm animals, and community activities significantly compromised maize yield. However, the remittance income offsets the loss. As women's role in agriculture is central, especially in the context of male labor out-migration, gender-transformative approaches to research and development practices would ensure social justice and equitable benefit sharing. Accounting for their choices and preferences in developing and designing agricultural interventions is thus vital for the long-term sustainability of the mountain farming systems.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"17 3","pages":"247 - 259"},"PeriodicalIF":3.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41286957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet the low agricultural productivity of this sector challenges the realisation of this pathway. Through comparison with large-scale farmers, this review sought to elicit the main reasons for differences in productivity and explore the prospects of small-scale farming. It highlights that low productivity of small-scale farming cannot be solely ascribed to biophysical constraints and that differences rather arise at farm and regional level. Therefore, intervention strategies should not be solely sought at field scale, which seems to be the norm. While the prospects of small-scale farming may seem gloomy at first glance, opportunities such as investing in horticulture exist. Prospects for small-scale farming are limited by the country's very competitive and thriving large-scale farming that saturate most agricultural markets. A key conclusion from this review is that we still do not know enough about small-scale farming systems in South Africa. For example, what is the contribution of small-scale farming to the living income of households? Are farming households food and nutrition secure? In particular, the role of agriculture in improving rural livelihoods is poorly understood. Farming is likely to remain an important supplementary livelihood opportunity for the majority of rural households. As such, small-scale farming needs to be rethought as part of a broader livelihood strategy by all stakeholders while continuously seeking alternative entry points towards thriving rural livelihoods. This means provision of support for transition to more commercial farming activities for those with interest and sufficient resources, while alternative employment or social protection is provided for others. A key question for research is what types of farming (crops and livestock) and what scale of operation is needed to achieve commercial success in different regions.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"139 - 154"},"PeriodicalIF":3.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41433553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its agriculture sector has demonstrated rapid intensification and modernization. Agricultural best management practices (BMPs), e.g., drum seeders and laser land levelling, were introduced to rice farmers in Bago Region in 2012 to increase sustainable production and counter negative environmental impacts. The objective of this study was to determine the socioeconomic and agronomic changes due to the adoption of BMPs between adopters and non-adopters. Using a digital survey questionnaire application to collect household data, 200 farmers in eight villages were interviewed in 2012 and 2017. Data were analysed using uni- and multivariate statistics. Mediation analysis was utilized to evaluate the effect of the farmer group on rice yields. Overall, all farmers in this study experienced substantial positive changes over the course of five years in line with the national development efforts. Differences among adopters and non-adopters were not significant, but notable distinctions existed between cropping patterns. Rice-pulse farmers had higher yields ( + 0.4 t/ha), yet rice-rice farmers had larger cultivation areas, received higher agricultural credits, and had superior income levels. Nevertheless, rice yields remained low (<4 t/ha). Education was found to be an important predictor of yield. Hence, this factor is crucial for accelerating agricultural development in Myanmar. Improving extension services and knowledge transfer are necessary to expand the dissemination of sustainable BMPs and make farmers more resilient against the negative implications of climate change.","PeriodicalId":54661,"journal":{"name":"Outlook on Agriculture","volume":"51 1","pages":"223 - 237"},"PeriodicalIF":3.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43665742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
