Does Conservation Agriculture Change Labour Requirements? Evidence of Sustainable Intensification in Sub-Saharan Africa

Population growth, increasing wealth and changing diets require agriculture in Sub-Saharan Africa to intensify to meet future food demand and ensure food security in the region. Conservation agriculture can increase yields in the long run and reduce the negative environmental impacts of intensive farming. In changing the mix of resources used and how they are managed, the adoption of conservation agriculture can have a direct impact on farm labour. We study the relationship between conservation agriculture and labour input requirements as observed in five Sub-Saharan African countries. We focus on the amount of work required and the source of the work employed (household or hired, by gender, by children and by production stage). We apply multinomial endogenous switching regression models on a panel of household and farm data from Ethiopia, Kenya, Malawi, Mozambique and Tanzania. We find that conservation agriculture increases farms’ labour input requirements. Higher demand is driven by more work during the harvesting and threshing stages. Increases in labour requirements are usually met by household labour, not paid work. The workload change is also higher for women than for men, and, in certain cases, is met by children.     

Demand for Seasonal Wage Labour in Agriculture: What Does Family Farming Hide?

This article draws on the agricultural household literature to understand the dynamics of wage labour on farms in a context of family farming. The recent evolution towards an increased use of seasonal wage labour motivates the original distinction of three types of labour: family labour, permanent‐wage labour and seasonal‐wage labour. Considering the two wage labour types and hiring cost for seasonal workers, our empirical results based on 2000 French data on fruit and vegetable farms suggest that the choice between hiring permanent or seasonal wage labour is not only determined by the seasonality of the activity. Indeed, the characteristics of the local labour market also affect the trade‐off between permanent and seasonal wage labour. This result provides insights on the substitutability of the two labour types, especially when the local labour market is tight. Moreover, the substitution of seasonal‐wage labour for permanent‐wage labour can occur in the agricultural sector as a mean of increasing flexibility as well as reducing costs and commitments. Finally, family labour is found to substitute for wage labour and more specifically for seasonal‐wage labour.     

Institutions and agricultural productivity in Sub-Saharan Africa

Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985 to 1999 was a strong 1.90% per year. Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in productivity. We measure a significant reduction in productivity during political conflicts and wars, and a significant increase in productivity among those countries with higher levels of political rights and civil liberties.     

Survey and Analysis of Labour on Organic Farms in the UK and Republic of Ireland

A survey of 1144 organic farms in the UK and Republic of Ireland (IE) was used to assess whether organic agriculture provides more labour than conventional (nonorganic) farming. The sampled farms comprised 23% of all organic farms. The jobs per farm and per area varied greatly with enterprise type and farm size, and between regions. Comparison of the survey with national statistics showed that organic farms employ 135% more FTE (full time equivalent jobs) per farm than conventional farms. The mean jobs per area was markedly lower for organic farms (1.35 compared to 2.43 FTE per 100 ha), because they are larger (216 ha compared to 51 ha). Even when corrected for the different size distribution, organic farms had more jobs per farm than the national averages (2.52 and 1.49 FTE for the UK and IE, compared to 1.28 and 1.16 FTE). The farm size weighted FTE per area for organic farms in the UK (4.33 FTE per 100 ha) was almost twice that for conventional farms. We predict there would be 19% and 6% more farming jobs in the UK and IE if 20% of the farms of both countries were to become organic (compared to the present 1–2%).     

Panel Estimates of the Canadian Rural/Urban Women's Wage Gap

This article analyzes the female rural-urban wage gap in Canada using longitudinal data from the Survey of Labour and Income Dynamics 1993–96. We estimate a two-step wage equation accounting for unobserved heterogeneity and sample selection. The results indicate that a statistically and economically significant rural-urban wage gap remains after controlling for observed and unobserved characteristics. Further, the results suggest this rural-urban wage difference is not simply induced by immobility between rural and urban markets. Rather, consistent with the effect of thinner rural labor markets, the evidence indicates that rural-urban differences in the impact of a number of explanatory variables are significant.     

Stories of Rural Accumulation in Africa: Trajectories and Transitions among Rural Capitalists in Senegal

This paper analyzes primary qualitative evidence from life histories of rural capitalists in contemporary Senegal. Various common themes in the declining literature on rural capitalism in Africa are discussed with reference to the specific individual trajectories of rural farm capitalists in Senegal. The themes include the emergence of rural capitalism in the context of protracted, uneven and gradual rural social differentiation and the various processes that have accompanied it; the condition of 'entrepreneurship' in such changing historical contexts; the symbiotic relationship between different spaces (loci) of accumulation, especially trade, transport and farming and the historical context in which they take place; the crucial but sometimes contradictory role of the state in spurring or constraining rural capitalist accumulation; and the variety of 'idioms of accumulation', which reflect transitions and synthesis between non-capitalist and capitalist forms of labour surplus appropriation at the level of individual capitalists, despite some uniformity in the general logic of capital and the spread of capitalist relations of production and exchange. The paper also discusses the methodological power and limitations of oral narratives as a method to gather evidence on long-term processes of agrarian change and accumulation in rural Africa. Finally, the life histories shed some light on the origins of rural capitalists and show that there is a combination of instances of 'capitalism from above' and 'from below' but that no dominant pattern can be clearly discerned at least in the space of one or two generations.     

From researcher to farmer: partnerships in integrated aquaculture—agriculture systems in Malawi and Cameroon

The potential for integrating aquaculture with agriculture has been widely recognized as a means of improving the use of inputs, diversifying output and economic opportunity, and enabling smallholder producers to maintain and strengthen livelihoods. This paper describes the outcomes of this approach and explains the extent to which it has been taken up and has led to sustained and self-generated capacity. Based in particular on experience in Malawi, Ghana and Cameroon, it also considers implications more widely in the region. The overall picture is that this is a partial and still emerging success story, linked as much with the social and economic drivers surrounding smallholder farmers as with the development support approach adopted.     

Employment Growth, Worker Mobility, and Rural Economic Development

A county-level labor market model is estimated for North Carolina. The model accounts for inter-county commuting, migration, and within-county adjustments to labor demand shocks. Econometric results indicate that most employment growth (70–80%) during the 1980s was accommodated by changes in commuting flows. Evidence is also presented indicating that labor force growth—and, by extension, population growth and associated fiscal impacts—in rural counties is sensitive to employment growth in nearby urban counties. These results highlight two opposing forces related to spatial spillovers that are usually neglected in analyses of the economic and fiscal impacts of employment growth.     

森林资源禀赋、改革路径选择与我国农村林业发展

为什么华北平原地区的林业改革和发展快于森林资源丰富地区?“资源的诅咒”这个发展经济学的经典假说,在市场转轨国家是否存在不同的作用机理?本文以一组不同森林资源丰裕度村1986～2004年的面板数据为样本,检验了森林资源丰裕度对我国农村林业改革与发展的影响。统计观察和计量分析结果都显示,“资源的诅咒”在我国不同地区的农村林业发展中成立,森林资源丰富的林业村和山区村林权改革和林业发展都显著落后于少林的平原村,丰富的森林资源通过“转轨成本”抑制了重点林区的林业改革,延缓了林业发展。研究还发现,林权改革有利于推动我国农村地区的林业发展。研究的政策意义在于:指出森林资源禀赋在市场转轨国家的林业发展中构成改革的变量,农村林业改革应设计多样化的改革方案,提高改革绩效,农村林业发展的重点应当转向山区。     

The Struggle for Alternatives: NGOs' Responses to the World Development Report 2008

This paper analyzes the response by NGOs to the 2008 World Development Report (WDR08). It does so at two levels of analysis, which in turn reflect two possible ways of reading the WDR08. The first is to read the WDR08 as a document for policy guidance on 'agriculture for development'. In this respect the paper shows how NGOs expose and challenge the WDR08's optimism for the benign impact of unregulated agribusiness investment on poverty reduction, and put forward a convincing alternative. The second, and politically more fertile, way of reading the WDR08 is to make sense of its numerous internal contradictions. These contradictions are functional to the World Bank's hegemonic effort of establishing a common, and broader, agenda for rural development. Having highlighted the WDR08's incoherent messages on (i) rural labour markets and their role in poverty reduction and (ii) what constitutes the most promising driver of poverty reduction in agriculture (returns from wage labour vs from own account farming), the paper documents NGOs' failure to detect and politically exploit these contradictions.     

Information,efficiency, and welfare in agricultural markets

Information and communications technologies (ICTs) have spread rapidly in the developing world. There has been considerable interest in the potential role ICTs, particularly mobile phones, have begun to play in the marketing of agricultural outputs in these countries. In this article, we discuss the potential impacts ICTs may have on welfare, both in terms of potential efficiency gains (via improved arbitrage), and welfare transfers among agents in the supply chain (via reduced informational asymmetries and market power). We also review the recent empirical evidence for such effects.     

农村劳动力流动与三次产业结构调整的内生性研究

[目的]劳动力是经济发展的重要元素之一,大量农村劳动力流动制约着社会经济的发展。自1978年改革开放以来,我国三次产业结构均进行着调整,而随着农业现代化的发展,导致大量农村劳动力外流,而这种外流受三次产业结构调整的影响,因此农村劳动力流动与三次产业结构调整存在很大的关联。[方法]为了探寻二者之间的关系,文章利用1978~2014年面板数据,通过GMM三阶段分析法将农村流动劳动力流入各产业的比重变化,与三次产业结构比的变化进行描述性的对比分析,并建立联立方程及模型。[结果]研究表明:大量农村劳动力脱离土地,从第一产业流向第二、三产业;在我国进行产业结构优化升级和社会不断发展的过程中,第二、三产业吸纳了大量的农村剩余劳动力,形成了劳动力的流动;农村劳动力流动与三次产业结构调整存在相互影响相互作用的内生性关系。[结论]并针对这一结论提出相应的政策建议,对更好的引导农村流动劳动力和产业结构调整优化具有重要的理论和实践意义。     

The trade distorting effects of export refunds: The case of beef exports to Africa

The usual sale of European agricultural products to Africa using export refunds has been heavily discussed in recent decades. At the centre of the discussion are the consequences on the agricultural producers in Western and Southern Africa. There are two different points of view: On the one hand, the European Union's (EU) export policy reduces the prices on these markets and relieves high burdens on local producers; on the other hand are claims that refunds do not influence local prices significantly. Hence, the Common Agricultural Policy (CAP) has no effect on markets of third countries, besides depressing world market prices. This paper focuses on the effects of EU's export subsidies for beef exports on its market share in several developing countries. Twenty-seven African countries were analysed using a fixed-effects model between 1988 and 2000. The results clearly show a highly significant positive impact of the export refund rate on the market and the import share. With its export policy, the EU raises its market position and edges out other competitors.
