Methods, results and policy implications of poverty and food security mapping assessments

The importance of poverty reduction to the world development agenda has motivated greater interest in the geographic dimensions of poverty and food security. This special issue of Food Policy includes examples of poverty and food security mapping used to support policy development in agricultural and rural areas. The volume includes eight country case studies and one cross-country comparison that illustrate advances in our capacity to assess welfare over large areas and at detailed spatial resolutions. Poverty mapping facilitates assessments of the role of environmental factors on the broad spatial pattern of poverty and food security. Evaluating proximity and accessibility in welfare outcomes can improve our knowledge of poverty patterns and processes. Spatial statistics can enhance our understanding of geographic and neighbourhood effects on poverty and food security outcomes. The development of effective policies requires increased collaboration among stakeholders, researchers and policy makers in constructing and using poverty and food security maps.     

Spatial clustering of rural poverty and food insecurity in Sri Lanka

We mapped poverty, with reference to a nutrition-based poverty line, to analyse its spatial clustering in Sri Lanka. We used the Divisional Secretariat poverty map, derived by combining the principal component analysis and the synthetic small area estimation technique, as the data source. Two statistically significant clusters appear. One cluster indicates that low poverty rural areas cluster around a few low poverty urban areas, where low agricultural employment and better access to roads are key characteristics. The other indicates a cluster of high poverty rural areas, where agriculture is the dominant economic activity, and where spatial clustering is associated with factors influencing agricultural production. Agricultural smallholdings are positively associated with spatial clustering of poor rural areas. In areas where water availability is low, better access to irrigation significantly reduces poverty. Finally, we discuss the use of poverty mapping for effective policy formulation and interventions for alleviating poverty and food insecurity.     

Do poverty and poor health and nutrition increase the risk of armed conflict onset?

We analyze the effects of improving the economic, food security and health status on the risk of armed cotntectflict onset, focusing on the factors related to the millennium development goals. We employ the discrete-time hazard model that allows us to examine the time-varying effects of socioeconomic factors controlling for the reverse effect of conflict. Our results show that income poverty and poor health and nutritional status are more significantly associated with armed conflict onset than GDP per capita, annual GDP growth, and the ratio of primary commodity exports over GDP. In particular, poor health and nutritional status seems to play a key role in inducing armed conflicts in poor countries. These results indicate that, when a majority of the poor and the malnourished resides in rural areas and depends on agriculture directly or indirectly, investments in public goods for agriculture and rural areas can be effective tools to achieve the multiple goals of reduced poverty, food security and armed conflict, including riots in early 2008 triggered by high food prices. Food policy can be an effective element of efforts to maintain stability.     

The power of the vegetable patch: How home-grown food helps large rural households achieve economies of scale & escape poverty

This paper explores how the household’s capacity to grow food impacts their ability to achieve economies of scale in food consumption and how this impacts the geographic distribution of poverty across rural and urban areas. An accurate understanding of consumption economies of scale is vital for comparing poverty levels across households of varying size. Using Sri Lankan data on home-grown food consumption, we empirically confirm that such economies of scale exist and that large households tend to consume relatively more home-grown food than smaller households. The magnitude of these scale economies are found to be larger than those in market purchased food, but smaller than those found in housing expenditure. Consuming more home-grown food is also found to be positively correlated with per-capita calories consumed. Taking these effects into account in poverty estimates leads to a 15 per cent decline in the number of household who fall below the poverty line in rural regions.     

Towards regional food security in southern Africa: a (new) policy framework for the agricultural sector

In the southern African Region (SAR) large populations, mainly concentrated in rural areas, face food insecurity and poverty. Food insecurity is intensified by adverse weather conditions and droughts which impact negatively on farm level food production throughout the region. Agriculture constitutes an important economic sector in the majority of countries in the region. This is measured as share of agricultural value added to the GDP and as agriculture's share in employment. Based on these facts alone, it must be obvious that sustained agricultural performance will play a significant role in the improvement of food security and livelihoods in the region. However, food security is not only attained in rural areas and by the consumption of home produced food stuffs. Urbanisation is expected to increase dramatically over the next few decades and feeding the urban masses, at affordable prices, must be considered to be a high future priority for governments in the region. Food security must not be viewed as an agricultural issue per se. The drive to food self sufficiency through domestic agriculture production in many countries in the region did not enable these countries to feed their own population. Food security should rather be defined as the acquirement of sufficient and nutritious quantities of food (Sen, 1981, Poverty and Famines: An essay on Entitlement and Deprivation). An approach, whereby attention is given to the macro level availability of food, access to income streams as well as improved production capacity to acquire food at a household level and the utilisation of nutritious food, should therefore be guiding food security policies (SADC: FSTAU, 1997, A Strategic Framework for Food Security in the Region). This broader view emphasises household level poverty reduction, economic development and growth as important components of a food security strategy (World Food Summit, Rome, 1996). An important issue which therefore needs to be explored is whether agriculture does have the potential to contribute to economic processes, which will support broad based development and food security. This paper is intended to argue the importance of agricultural development for food security in the region and to develop a diverse policy framework to strengthen this new, more comprehensive role of agriculture in the region.     

Targeting agricultural research to benefit poor farmers: Relating poverty mapping to maize environments in Mexico

We explore approaches for targeting agricultural research to benefit poor farmers. Using small area estimation methods and spatial analysis, we generated high-resolution poverty maps and combined them with geo-referenced biophysical data relevant to maize-based agriculture in Mexico. We used multivariate classification and cluster analysis to synthesize biophysical data relevant for crop performance with rural poverty data. Results show that the rural poor are concentrated in particular regions and under particular circumstances. Formal maize germplasm improvement trials were largely outside the core areas of rural poverty and there was little evidence for direct spillover of improved germplasm. Agro-climatic classification used for targeting breeding is useful but often ignores some important factors identified as relevant for the poor. Combining this method with poverty mapping improves stratifying and targeting crop breeding efforts to meet the demands of resource-poor farmers. We believe this integrated approach will help increase benefits from agricultural research to poor rural communities.     

Local poverty reduction in Chile and Mexico: The role of food manufacturing growth

This paper analyzes the relationship between local poverty and food manufacturing growth in Chile and Mexico using propensity score matching, differences in differences and spatial econometrics methods. We focus on food manufacturing as a sector with a number of characteristics that make it potentially pro-poor, and whose incentives for spatial distribution may either strengthen or dampen its poverty reduction potential. The overall results indicate growth in food manufacturing employment contributes to local poverty reduction.     

Is the locus of poverty changing?

Urbanization is now a dominant demographic phenomenon in low- and middle-income countries. By the year 2000, half of the world's population will live in urban areas; of this half, two thirds will be in developing countries, predominantly in Asia. Whether there will be a corresponding shift of poverty from rural to urban areas is the central question of this analysis. Evidence from cross-sectional, time-series, and case data indicates that the percent of poverty in urban areas is dependent on income levels, income growth, and income distribution. The evidence also indicates that the number of poor in rural areas will exceed those in urban areas well into the 21st century. These poverty and urbanization trends are significant politically, and important also with respect to food policy and required investments in agriculture.     

Non-agricultural earnings in peri-urban areas of Tanzania: evidence from household survey data

This study draws on purposive survey data of approximately 600 households in peri-urban Tanzania to describe the degree and nature of non-farm diversification in these settings. With the exception of relatively dynamic cities such as Dar es Salaam and Arusha, overall non-farm incomes shares are not unambiguously higher than in rural areas as a whole. Non-farm income shares rise sharply and monotonically with quintiles defined in terms of per capita food consumption. In that sense the sector appears to offer an important route out of poverty. The evidence suggests that education, and access to infrastructure, are important determinants of non-farm incomes in peri-urban areas. Women appear to be poorly placed vis à vis the non-farm sector, even after controlling for education, age and other characteristics. Kinship and tribal affinities, and time devoted to communal activities, appear to deter entrepreneurial activity and non-farm employment, but trust in officials and public servants and strong heterogeneous village associations, are important in stimulating non-farm activity.     

A quantitative analysis of poverty and livelihood profiles: The case of rural Rwanda

The paper applies a quantitative methodology to study poverty and livelihood profiles on the basis of a large set of variables. It takes the context of post-conflict rural Rwanda for a case study. By means of exploratory tools (i.e. principal component and cluster analysis), it combines variables that capture natural, physical, human, financial and social resources together with environmental factors to identify household groups with varying livelihoods. The paper further explores how these clusters differ with regards the incidence of poverty, livelihood strategies and their respective crop preferences. The paper concludes that Rwandan rural policies should adopt distinct and appropriate interventions for impoverished peasant groups, each having their own particular livelihood profiles.     

Mapping natural resource-based poverty,with an application to rural Syria

This study presents advances in resource-based poverty mapping. It illustrates how agricultural income distribution maps can be generated at small pixel-level, providing an application of the approach in rural Syria. Census data on agriculture and population are disaggregated based on pixel-level agricultural productivity coefficients derived in a GIS environment. The approach, triangulated with survey results and compared with sub-national poverty maps, shows that the better-income areas of Syria are located in the irrigated and higher-rainfall areas, though lower-income pockets exist due to the presence of ecological and topographic factors or due to high population density. The method can be used for developing high-resolution, low cost maps for rapid detection of resource-driven poverty in low income countries where agriculture is a major source of rural income, and where poverty mapping is rarely undertaken due to the high costs involved.     

Fish as the “bank in the water” – Evidence from chronic-poor communities in Congo

Small-scale fisheries in developing countries are often perceived as being a low-productivity and backward informal sector. As a result they are rarely considered in poverty reduction programmes and rural development planning. In this paper, we investigate the dual role of fish as a food and cash crop through data collected in river fisheries in Democratic Republic of Congo (DRC). Fishing in this very remote rural region of DRC is operated both by men and women, as part of a household multiple activity livelihood strategy. The data shows that poor households rely heavily on fishing for their supply of protein-rich food, in particular through women’s subsistence catches. Fishing also appears to be the main source of cash-income for the majority of households, including local farmers. Based on these findings and a review of the literature, the paper argues that small-scale fisheries can play a fundamental role in local economies, especially in remote rural areas where they strengthen significantly the livelihoods of people through their role in both food security and cash-income generation.     

Impact of food inflation on poverty in the Philippines

We simulate the impact of food inflation between June 2006 and June 2008 on poverty across different areas and between agricultural and non-agricultural households. We explicitly treat the spatial heterogeneity in food inflation and the differences in consumption and production patterns across households by merging household expenditure survey and price datasets at the provincial level or lower. Although some of the poor agricultural households may have escaped poverty, the poorest of the poor, whether they are in an agricultural household or not, are severely and adversely affected by the food inflation.     

Social structure,reasonable gain,and entrepreneurship in Africa

In the context of desperate poverty, characterized by households at subsistence level that experience economic loss and social fracture, explanations for why individuals undertake entry into entrepreneurship are limited. We find that individuals rely on their social relationships to enable entrepreneurial activities that have the potential to create a reasonable income gain. In a sample of 1,049 households in rural Kenya, we test whether the disintegration of social structure attenuates entrepreneurial behavior. When coupled with factors such as income loss, gender of the household head, and access to communal resources, social structure plays a pivotal role in entrepreneurial action. We propose that the search for reasonable income gain is a key driver of entrepreneurial action at subsistence levels, thereby adding to behavioral explanations of entrepreneurship.

The food security challenge for southern Africa

This paper considers food security aims and instruments against a background of changed circumstances internationally and regionally. The international changes discussed are: a sharper focus on achieving macro-economic stabilization, which inter alia has led to closer scrutiny of what the public sector should be financing, and a decline in funding for agriculture; a reduced role for governments in commercial-type activities; the shift towards greater integration of world markets; and changing prospects for international aid flows. Regionally, southern Africa is moving away from a past of conflict and inward-looking economies, towards greater cooperation and trade, and less interventionist economic management.The commendable SADC food security strategy paper of June 1997 is considered, and its implications drawn out. The main messages are that (a) household food insecurity results from poverty, (b) national food insecurity results from faltering development and weak external trade performance, and (c) future strategies must therefore lie with greater efficiency in the use of resources and with patterns of development which are most effective in creating employment and incomes. Arguably there is therefore no case for a food security agenda that is separate from broad-based development aimed at poverty alleviation. This understanding of food security is at variance with some of the policies and development programmes in the region. Promotion of self-sufficiency in grains, specific food-security instruments, and controls over and interventions in markets may all be counter to improving food security for the region if they hinder policy and institutional reforms called for by the wider development agenda.The main roles for governments in promoting food security are discussed in terms of creating an enabling environment for development, correcting for market failures, and targeted measures to achieve social objectives. Food security needs both an urban and a rural focus, and involves all economic sectors. For rural areas, governments' roles may usefully be defined in terms of supporting household strategies aimed at raising and stabilizing incomes through livelihood diversification, intensification of farming, and migration.Two priority policy areas which are central to achieving food security objectives are discussed at some length: trade policy and the promotion of smallholder farming. The roles of government in these areas are discussed in the light of economic theory and past experiences in the region. A vision for a future trade regime is outlined, and strategic interventions by governments are identified. The challenge for governments in supporting smallholder farming is, first, to define with greater rigour than in the past the priority uses for public funds, and, second, to find much more efficient ways of delivering services than in the past. It will otherwise be difficult to make a case for reversing the decline in public funding for the sector.The paper ends with brief discussions of the roles for aid and for SADC in promoting food security, and with a question of whether a new initiative is needed to strengthen trade policy skills in the region.     

What is the irrigation potential for Africa? A combined biophysical and socioeconomic approach

Although irrigation in Africa has the potential to boost agricultural productivities by at least 50%, food production on the continent is almost entirely rainfed. The area equipped for irrigation, currently slightly more than 13 million hectares, makes up just 6% of the total cultivated area. More than 70% of Africa’s poor live in rural areas and mostly depend on agriculture for their livelihoods. As a result, agricultural development is key to ending poverty on the continent. Many development organizations have recently proposed to significantly increase investments in irrigation in the region. However, the potential for irrigation investments in Africa is highly dependent upon geographic, hydrologic, agronomic, and economic factors that need to be taken into account when assessing the long-term viability and sustainability of planned projects. This paper analyzes the large, dam-based and small-scale irrigation investment potential in Africa based on agronomic, hydrologic, and economic factors. We find significant profitable irrigation potential for both small-scale and large-scale systems. This type of regional analysis can guide distribution of investment funds across countries and should be a first step prior to in-depth country- and local-level assessment of irrigation potential, which will be important to agricultural and economic development in Africa.     

Environmental and health benefits of hunting lifestyles and diets for the Innu of Labrador

The Innu of northern Labrador, Canada have undergone profound transitions in recent decades with important implications for conservation, food and health policy. The change from permanent nomadic hunting, gathering and trapping in ‘the country’ (nutshimit) to sedentary village life (known as ‘sedentarisation’) has been associated with a marked decline in physical and mental health. The overarching response of the national government has been to emphasize village-based and institutional solutions. We show that changing the balance back to country-based activities would address both the primary causes of the crisis and improve the health and well-being of the Innu. Drawing on ethnographic fieldwork, interviews with Innu older people (Tshenut), empirical data on nutrition and activity, and comparative data from the experiences of other indigenous peoples, we identify pertinent biological and environmental transitions of significance to the current plight of the Innu. We show that nutrition and physical activity transitions have had major negative impacts on individual and community health. However, hunting and its associated social and cultural forms is still a viable option as part of a mixed livelihood and economy in the environmentally significant boreal forests and tundra of northern Labrador. Cultural continuity through Innu hunting activities is a means to decelerate, and possibly reverse, their decline. We suggest four new policy areas to help restore country-based activities: (i) a food policy for country food; (ii) an outpost programme; (iii) ecotourism; and (iv) an amended school calendar. Finally, we indicate the implications of our analysis for people in other countries.     

Resettlement: Zimbabwe's first step

More than a year after independence, the main changes in agriculture in Zimbabwe have been minimum wage legislation, a high maize price accompanied by an exceptionally good growing season, the UNHCR (United Nations High Commission for Refugees) reinstallation and food programmes and the small beginnings of resettlement (and larger numbers of squatters). Certain food subsidies also affect rural areas although their greatest benefits accrue to those with urban incomes and urban diets. In addition the ‘former tribal trust lands’ are subject to increasing politicization as the newly elected district councils flex their muscles, providing at the same time an apparent attempt at decentralization and local participation with greatly increased expectations of assistance from the state. The future is uncertain, but it is evident that while the standard of living for the majority in rural areas remains so starkly low, the government will be forced to contend with sharply polarized forces, both within and outside the state apparatus, that seek to speed or dissipate the rate of change.     

The impact of the European Novel Food Regulation on trade and food innovation based on traditional plant foods from developing countries

The stringent food safety assessment for novel foods required by the European Union’s Novel Food Regulation (NFR) places a high burden of proof on those bringing traditional food products to the EU market not consumed in the EU prior 1997. The regulation has emerged as a non-tariff trade barrier for heritage foods from developing countries that are viewed as “exotic” from the EU perspective. We show how the regulation has discouraged investment in supply chains and market development, and how this negatively affects income generation and rural poverty alleviation in developing countries. Focusing on plant-derived foods, this paper proposes to recognize traditional exotic foods in current EU law as a food category sui generis with food safety evidence requirements being proportionate to the risks they may pose. We argue that development activities promoting export food chains must increasingly accommodate legitimate food safety concerns about neglected food species in project design and seek to generate data to enhance regulatory acceptance in target markets.     

Assessing household food insecurity experience in the context of deforestation in Cameroon

BackgroundIn forest areas, reconciling strategies to halt deforestation and concerns to improve sustainable food supply and access is a great challenge to development planners and forest managers. This paper gathered evidence on the relationship between deforestation and food insecurity. The study was executed in Cameroon’s forest areas which constitute 10% of the Congo basin forest - an area characterized by increasing deforestation and high levels of poverty and food insecurity (FIS). The objective was to understand the characteristics, prevalence and severity of household FIS as deforestation increases. The HFIAS 9-item questionnaire for measuring experience-based FIS was used for data collection and analysis.ResultsAt least one-third of households at all levels of deforestation were severely food insecure and more than half of the population suffered from moderate to severe FIS. Most (97%) households reported experiencing food scarcity due to lack of resources. Households in the least deforested zone were better off than those in moderate and most deforested zones by most of the FIS indicators, while differences between the moderately and the most deforested zones were less distinct. Overall, considering a range of food insecurity indicators, households in the most deforested zone were the worst off.ConclusionHousehold FIS deteriorates with increasing deforestation and despite the generally favourable environmental conditions for food production, FIS was still high. This finding has major implications for development practitioners, land use planning, food security and conservation initiatives.
