The promise (and pitfalls) of ICT for agriculture initiatives

The widespread growth of information and telecommunication technologies (ICTs) in rural areas of developing countries offers new opportunities to provide more timely and low‐cost information services to farmers, as well as assist in coordinating agricultural agents. Over the past decade, the number of public and private sector initiatives in this space has increased substantially, with over 140 deployments worldwide in 2015. While there is substantial potential for such services to address farmers’ and traders’ information and credit market constraints, economic research suggests that the impacts of such services on agricultural adoption, behavior and welfare is mixed. While this can, in part, be explained by the degree of the information asymmetry and the presence of other market failures in different contexts, research from other disciplines provides additional insights into these findings. In particular, work in the domain of human–computer interaction (HCI) focuses heavily on users’ interaction and experience with a given technology, thus explaining why users may not fully engage with ICT‐based agricultural interfaces. Furthermore, sociological and anthropological approaches study the provision of information and trust and how these may be altered by ICT platforms. Drawing upon these disciplines, we suggest that future ICT for agriculture initiatives should first seek to better understand the information and complementary market failures in a given context, in order to better understand whether information is a binding constraint. Second, even if information is missing, the information services provided should be of high quality and from a trusted source, which can be a challenge with some ICT platforms. Finally, such services should be delivered via platforms that build upon local ICT access and usage, paying particular attention to the gender digital divide.     

Policies for sustainable development in the hillside areas of Honduras: a quantitative livelihoods approach

In this article, we use data for 376 households, 1,066 parcels, and 2,143 plots located in 95 villages in the hillside areas in Honduras to generate information needed by decision makers to assess the needs and opportunities for public investments, and design policies that stimulate natural resource conservation. We develop a quantitative livelihood approach, using factor and cluster analysis to group households based on the use of their main assets. This resulted in seven household categories that pursue similar livelihood strategies. We use a multinomial logit model to show that livelihood strategies are determined by comparative advantages as reflected by a combination of biophysical and socioeconomic variables. While 92% of the rural hillsides population in Honduras lives on US$1.00/capita/day or less, households that follow a livelihood strategy based on basic grain farming are the poorest because they often live in isolated areas with relatively poor agro‐ecological and socioeconomic conditions. Opportunities for off‐farm work tend to be limited in these areas and household strategies that combine on‐farm work with off‐farm work earn higher incomes. Per capita incomes can be increased by improving road infrastructure, widening access to land, policies that reduce household size and dependency ratios, and adoption of sustainable land management technologies that restore soil fertility. We used probit models to show that the latter can be promoted by agricultural extension programs and land redistribution. Investments in physical assets should be directed toward households that pursue livelihood strategies based on off‐farm employment or coffee production, while agricultural training programs are best focused on livestock producers.     

Mobile Phones and Radios: Effects on Transactions Costs and Market Participation for Households in Northern Ghana

The literature on agricultural markets suggests that transactions costs are the main obstacles preventing households from participating in agricultural markets. We examine the impact of the recent massive penetration of information communication technologies (ICTs), particularly mobile phones and radios, in developing countries to investigate the role of information in economic transactions and participation in food crop markets. To fully capture market participation behaviours, the current theoretical framework on market participation and transactions costs is extended to include those households that sell and buy in the same time period. We correct for endogeneity and selectivity throughout our models. We used a novel dataset of 393 households in northern Ghana with detailed information on market transactions and ICTs usage. Results show that receiving market information via mobile phones has a positive and significant impact on market participation, with a greater impact for households with a surplus of food crops. We find that radios have a larger impact on the quantity traded. This may reflect the nature of mobile phones in reducing searching costs, whereas radios provide an updated and regular flow of information which affects the pattern of crops consumed and sold. We also emphasise that the most significant factor is how ICTs are used, rather than their ownership.     

Livelihood roles of cattle and prospects for alternative land uses at the wildlife/livestock interface in South Africa

The emergence of wildlife ranching as an alternative land use option to agriculture, in Transfrontier Conservation Areas (TFCAs), has cast renewed interest on the role of cattle farming in rural livelihoods in areas close to wildlife parks. This study analysed the contribution of cattle to livelihoods and relationships between cattle and potential wildlife land uses in rural areas near Kruger National Park. Data were collected through household surveys, key informant interviews and community workshops. About 11% of households studied owned cattle, and cattle income constituted 29% of total household income. Benefits from cattle were also derived by households without cattle. About 71% of households had at least three sources of income, reflecting diversity of livelihoods. Wildlife related land uses were perceived by some households as threatening cattle production, whilst others viewed them as opportunities for alternative livelihoods. We conclude that cattle production has important livelihood roles, but is not sufficient as a driver of economic development in these areas. Incentives to encourage diversification of livelihoods at the wildlife/livestock interface, with possibilities for rural communities to explore wildlife based land uses should be put in place. In addition, land use policy and planning in such areas should focus on creating institutional mechanisms through which programmes integrating conservation and rural development goals can benefit rural communities.     

Drivers of sustainable intensification in Kenyan rural and peri-urban vegetable production

Sustainable intensification promotes environmentally sound and productive agriculture. However, use of sustainable intensification practices (SIPs) is low in many sub-Sharan African countries. This study examined the adoption of SIPs in Kenyan rural and peri-urban vegetable production to understand the scale of and underlying factors in the use of SIPs. A multistage sampling technique was employed to randomly select 685 rural and peri-urban vegetable farm households. Household data was then collected and anaylsed for four practices namely improved irrigation, integrated soil fertility, organic manure and crop diversification using a pre-tested structured questionnaire. A multivariate probit model was run to model simultaneous interdependent adoption decisions. Adoption of organic manure and African indigenous vegetables (AIV) diversification was high in both rural and peri-urban areas. However, adoption of improved irrigation systems and integrated soil fertility management was low, and even significantly lower in rural areas than in peri-urban areas (p?相似文献   

Long-term consequences of short-term precipitation shocks: evidence from Brazilian migrant households

We find that large short-term precipitation shocks damage the long-term income of households that have permanently migrated from rural to urban areas. This outcome is consistent with the behavior of credit-constrained rural households who are willing to accept lower long-term income in urban areas following the depletion of their productive assets during an adverse shock. Our empirical evidence suggests that there may be a link between large precipitation shocks in rural areas and urban poverty. Further exploration is warranted on the mechanisms by which natural disasters cause these long-term losses.     

A trait-based model of the potential demand for a genetically engineered food crop in a developing economy

We predict the potential demand of smallholder farmers for genetically transformed varieties of a food crop, the cooking banana of the East African highlands. Farmer demand for planting material is derived in an agricultural household model that accounts for variety traits and missing markets. The demand for candidate host varieties is predicted using a Zero‐Inflated Poisson (ZIP) regression system. The fitted model is used to illustrate the sensitivity of farmer demand for improved planting material to (a) investments in research and development, represented by the effectiveness of gene insertion and expression, and (b) other public investments in education, extension, and market infrastructure that support diffusion. By comparing the characteristics of agricultural households we demonstrate that the choice of host variety can have social consequences, favoring one rural population compared with another. Clients for transgenic banana planting material are likely to be poorer, subsistence‐oriented farmers in areas greatly affected by biotic constraints. A model of this type might be useful in assessing the investments needed to support the systematic dissemination of improved planting material. The approach can be generalized to other crop biotechnologies for smallholder farming systems, particularly in developing economies.     

Harnessing sustainability,resilience and productivity through conservation agriculture: the case of likoti in Lesotho

Subsistence farmers in Lesotho have been able to boost agricultural yields and increase food production by adopting conservation agriculture. The practice, locally known as likoti, also contributes to combating soil erosion and to enhancing fertility. The socio-economic and environmental benefits help poor households to rehabilitate and strengthen their livelihood capital base and ultimately help rural communities to build system resilience in the face of widespread poverty and increasing vulnerability that affect the country. This paper discusses the major advantages associated with the spread of likoti. By drawing on primary data collected by FAO-Lesotho, it enquires into the determinants of adoption, thereby highlighting constraints and options for future up-scaling. The results show that attending appropriate training is a crucial prerequisite for the correct adoption of likoti. However, training is more effective when trainers pursue true participation and when social capital among farmers is stronger. Further important determinants of adoption are the level of education and the economic incentives provided to vulnerable households. Stronger policy and institutional support in all these areas would thus help address the cultural and resource constraints that limit the full potential of likoti to be harnessed and ultimately hinder its further spread throughout the country.     

The effects of a large discrete maize price increase on the distribution of household welfare and poverty in rural Kenya1

This study estimates the effects of a large discrete maize price increase on the welfare of a sample of rural Kenyan households. The usual first‐order welfare approximation formula is extended to a second‐order formula that allows for supply and demand responses to the price change. Results show that many rural households are not affected greatly by the price change, and there are about as many gainers as losers. However, these full sample results mask important differences across regions. Welfare gains generally take place in major production areas while losses are in areas where most households are net buyers of maize. Semiparametric methods are used to investigate the relationship between income and the size of the welfare effect, and poverty dominance techniques are applied to study the impacts of the maize price increase on rural poverty.     

Analyzing the women’s empowerment and food security nexus in rural areas of Azad Jammu & Kashmir,Pakistan: By giving consideration to sense of land entitlement and infrastructural facilities

A rich body of literature exists for explaining the role women play in ensuring their household’s food security; however, as far as their own food security is concerned, little attention has been given. Therefore, this research collects evidence on the relationship between women’s empowerment and their own food security (access) in the rural areas of Azad Jammu & Kashmir (AJK). Data were collected from the households of 600 rural women. The results provide insights that the domains of legal rights, information and communication technologies (ICTs), social support and familial rights, can be a significant pathway for enhancing the food security of women as more bargaining power of women over the utilization of resources could result in a good quality of food choices and more expense on food items due to these rights. Besides, understanding food insecurity also requires considering gender norms as in this study, the infrastructural facilities and sense of land entitlement provide unexpected non-significant results. Though women help in the mounting necessities of their families, they are unable to enhance the food requirements for themselves due to restricted mobility and less economic opportunities. This is mainly due to the poor infrastructure, and more importantly, the lack of access to resources, especially land, because of lack of knowledge and self-confidence. Notably, the fear of conflict and domestic violence may also impede women from fighting for their rights, which results in poor access to food. Hence, by understanding the household makeup from women’s perspectives and customs, the findings from this study can help and guide policymakers in developing more appropriate strategies to improve the food security of women.     

Poverty decline, agricultural wages, and nonfarm employment in rural India: 1983–2004

We analyze five rounds of National Sample Survey data covering 1983, 1987/1988, 1993/1994, 1999/2000, and 2004/2005 to explore the relationship between rural diversification and poverty. Poverty in rural India has declined at a modest rate during this time period. We provide region-level estimates that illustrate considerable geographic heterogeneity in this progress. Poverty estimates correlate well with region-level NSS data on changes in agricultural wage rates. Agricultural labor remains the preserve of the uneducated and also to a large extent of the scheduled castes and scheduled tribes. We show that while agricultural labor grew as a share of total economic activity over the first four rounds, it had fallen back to the levels observed at the beginning of our survey period by 2004. This all-India trajectory also masks widely varying trends across states. During this period, the rural nonfarm sector has grown modestly, mainly between the last two survey rounds. Regular nonfarm employment remains largely associated with education levels and social status that are rare among the poor. However, casual labor and self-employment in the nonfarm sector reveals greater involvement by disadvantaged groups in 2004 than in the preceding rounds. The implication of this for poverty is not immediately clear—the poor may be pushed into low-return casual nonfarm activities due to lack of opportunities in the agricultural sector rather than being pulled by high returns offered by the nonfarm sector. Econometric estimates reveal that expansion of the nonfarm sector is associated with falling poverty via two routes: a direct impact on poverty that is likely due to a pro-poor marginal incidence of nonfarm employment expansion; and an indirect impact attributable to the positive effect of nonfarm employment growth on agricultural wages. The analysis also confirms the important contribution to rural poverty reduction from agricultural productivity, availability of land, and consumption levels in proximate urban areas.     

Did the commodity price spike increase rural poverty? Evidence from a long‐run panel in Bangladesh

We assess the effects of the dramatic rise in agricultural commodity prices during 2007–2008 on income dynamics and poverty among rural households in Bangladesh. A unique panel data set allows us to put the effects of recent events in the context of long‐run trends in income and poverty. We use data from a nationally representative longitudinal survey of rural households in Bangladesh collected in four waves in 1988, 2000, 2004, and 2008. Nargis and Hossain (Nargis, N., Hossain, M., 2006. Income dynamics and pathways out of rural poverty in Bangladesh, 1988–2004. Agric. Econ. 35, 425–435) analysed income dynamics and poverty incidence for the first three waves, finding a declining trend in both the incidence and severity of poverty, aided in particular by human capital development and off‐farm employment opportunities. We update and extend the analysis to include data collected in 2008, at the height of a spike in agricultural prices. We find that the price of a balanced food basket increased by more than 50% during 2000–2008, while household income rose only 15%. As a result the incidence and severity of rural poverty in Bangladesh sunk to pre‐2000 levels during 2004–2008. Thus, the price spikes in 2007–2008 helped push an additional 13 million people into poverty in rural Bangladesh. Moreover, we find that the determinants of poverty have not been time‐invariant. In particular, agricultural production, which had previously been associated with a higher incidence of poverty, served as a hedge against higher food prices during 2004–2008.     

Urbanization strategies, rural development and land use changes in China: A multiple-level integrated assessment

This paper links urbanization strategies to changes in land use and associated impacts on rural communities and agro-ecosystems in a rural area of China. Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets.     

不同地貌类型农户农业投入质量特征——基于安徽省农户的实证调查

农户作为农业生产投入的微观主体,其农业投入行为对农业和农村经济发展影响重大。以安徽省平原地区和丘陵山区23个县(市、区)的353个农户抽样调查数据,构建农户投入质量模型,分析不同地貌类型的农户农业投入质量。结果表明:①平原地区农户土地投入质量、资本投入质量优于丘陵山区,而劳动力投入质量劣于丘陵山区;②土地投入质量低可能是丘陵山区农户资本投资收益低的原因之一,增加农业基础设施投人是使农业摆脱困境的根本途径;③劳动力投入表现出兼业化、劣质化,应鼓励耕地有序流转,扩大农户耕地经营规模,使耕地集中到种粮专业户手中;④农户农业投入主要是流动资本,固定资本投入较少,农药、化肥投入一直处于上升趋势,其施用已经进入"进退维谷"中。     

Impact of cooperatives on smallholders' commercialization behavior: evidence from Ethiopia

This article examines the impact of marketing cooperatives on smallholder commercialization of cereals using detailed household data in rural Ethiopia. We use the strong government role in promoting the establishment of cooperatives to justify the use of propensity score matching to compare households that are cooperative members to similar households in comparable areas without cooperatives. The analysis reveals that although cooperatives obtain higher prices for their members, they are not associated with a significant increase in the overall share of cereal production sold commercially by their members. However, these average results hide considerable heterogeneity across households. In particular, we find that smaller farmers tend to reduce their marketed output as a result of higher prices, whereas the opposite is true for larger farmers.     

农地确权、差序格局与新型城镇化

农地流转的差序格局化特征会怎样影响我国新型城镇化进程?本文以农地制度改革为着眼点,利用2015年CHFS微观数据,将农地确权、农地流转差序格局与新型城镇化三者置于同一框架下进行系统性分析。研究发现,农地确权与农地流转的亲缘化特征显著促进农业转移人口城镇化。进一步检验作用机制发现,二者在促进农业转移人口城镇化作用方面并行不悖,农村内部整合型社会资本能够弥补正式制度不足带来的农地产权风险。因此,本文认为应着力提升农地确权政策的执行效果,在构建起高效、合理、规范的农地流转制度的同时,促进农户间相互合作,加大力度培育以农户为主体的新型农业经营项目,平稳推进新型城镇化,实现城乡融合发展。     

The adoption of intensive monocrop horticulture in southern Cameroon

Results from a 1997 survey of 208 households in the humid forest zone of southern Cameroon indicate that African policy makers seeking to intensify agricultural production should focus attention on the horticultural sub‐sector. The survey, which gathered information on horticultural production practices, found that the average expenditure on agro‐chemical inputs by horticultural producers using monocrop production systems was 190US$/ha, which greatly exceeds the FAO reported national average expenditure of 6.50 US$/ha. A logit model of monocrop adoption indicated that the size of land holding per household had a negative effect on adoption, congruent with population‐driven technical change and that increases in unit transportation costs significantly decreased the probability of adoption. These findings suggest that policy makers should target horticultural intensification in areas of higher population density and promote investment in rural roads. The age of the household head had a significant negative and elastic effect on adoption, which in combination with an increase in the cohort of younger farmers in the rural population induced by macro‐economic events contributed to the spread of intensified horticulture. In the study area, roughly two‐thirds of rural households also produce cocoa and the quantity of cocoa produced was positively associated with adoption of intensive horticultural systems suggesting that export crop promotion indirectly facilitated diversification of agriculture. Women's participation in intensive monocrop production was limited and efforts to promote their greater involvement are recommended.     

The economic impact of cowpea research in Senegal: an ex-post analysis with disadoption

This study evaluates the impact of a long‐term research collaboration between the Senegalese Institute for Agriculture Research (ISRA), and the Bean/Cowpea Collaborative Research Support Program (CRSP) funded by the U.S. Agency for International Development (USAID). Adoption of the primary outputs from this collaboration, a nonchemical cowpea storage method and two short‐season cowpea varieties, were tracked through a series of farmer interviews in 1996, 1997, and 2004 in the main cowpea growing area of Senegal. Combined with information from an impact assessment in the late 1980s, this study draws on ex‐post adoption data from most of the product life cycle for the storage technology. The 2004 survey found that 60.4% of cowpea production in the main cowpea growing area of Senegal is stored in metal drums and that 69% of households use this storage technology; ISRA/CRSP improved short season varieties were determined to account for 3.6% of cowpea production. Baseline economic analysis of the most recent survey data, which includes benefits and costs of the storage technology and improved varieties, reveal an IRR to donor funding of 13%. The benefits of these technologies appear to be evenly distributed in the rural population on the basis of gender and ethnic background. Comparison of the rates of technology adoption over time, however, reveals that use of the storage technology may be decreasing; inclusion of this technology disadoption trend reduces the IRR by only 0.4% from the baseline estimate. Overall, estimated returns reveal that this collaboration has been a good investment for the U.S. and Senegalese governments, and other donors.

Specifying a poly‐period development programme for a family farm

Most measures of inequality focus on the distribution of income and resources. A potentially important additional source of inequality stems from unequal property rights protection. The aim of the present paper was to examine the existence and patterns of systematic within-country inequalities in effective land rights in Rwanda. While a large qualitative literature discusses the comparative land rights of different groups, there is a lack of systematic quantitative evidence on the existence of land right inequalities. The results of estimations drawing on data on the land tenure arrangements of over 17 000 Rwandan households do indeed suggest within-country inequalities in land rights. In particular, despite recent reform efforts to improve women's land rights, a gender gap in land rights was observed that persisted throughout the 2005–2011 period studied, highlighting that institutional development takes time and that changes in de jure legislation do not automatically translate into changes in effective rights. Moreover, conflict-displaced households and households resettled to newly constructed village settlements all report weaker land rights than their respective comparison groups.
