SUMMARYThis review examines contributions of interdisciplinary (ID) research to understanding interactions between environmental quality, food production and food security. Global patterns of food insecurity and crop production are reviewed in relation to climate, land use and economic changes, as well as potential productivity increases compatible with environmental conservation. Interactions between food production and global processes make food insecurity a complex problem that requires ID analysis at local to global scales. Census and satellite data contribute to understanding of global cropland distribution. Analysis of land-use change exemplifies research between natural and social sciences. Quantitative modelling of global climate change impacts indicates relatively greater potential food insecurity in developing countries. International food security is increasingly interconnected through economic globalization and incentives for increased food production are required. Societies may not be able to expand available cropland without significant environmental risks; enhanced land and water productivity are the major opportunities available to increase food production. This requires renewed efforts in ID work to design and implement sound and efficient agricultural management practices. Models need to be informed by data from field experiments, long-term measurements and watershed monitoring by ground and remote sensing methods. Agricultural intensification may spare natural land but lead to increased pollution and water demand; reconciling conservation and productivity is a critical need. ID work provides many opportunities for synergies including conservation agriculture at the local level, efficient use of inputs, smarter land use taking into account spatial patterns and landscape ecology principles, and improved water management at field, system, watershed and basin levels. Goal-directed ID research is crucial, since producers, practitioners and policy makers should be involved. Geospatial, biotechnological and precision agriculture technologies linked with models can help inform strategies to achieve sustainable food production increases that maintain environmental quality. Implementation also requires ID work to overcome impediments due to human factors and facilitate adoption by farmers.

This chapter challenges the uncritical pursuit of food self-sufficiency that has been rationalized as increasing the state’s preparedness against shipping disruption. It argues that this effort might increase food’s cost, and reiterates the point that local food is not necessarily fair as low-income consumers could be sidelined in the push for food localization. In contrast to the enthusiasm for promoting agriculture and local food production in the state, relatively little has been done in addressing food insecurity of the poor, especially by the state government. Food democracy needs to consider food security for all—particularly the poor and the marginalized.

Given a continuation of current trends, with increasing population growth and declining food production, Southern Africa (excluding South Africa) which could nearly feed itself during 1979–81, will be only 64 per cent self-sufficient by the turn of the century. Zimbabwe has a particularly important rôle to play in trying to prevent such a disaster. It is by far the most important exporter of food and cash crops in the region, and has been allocated the task of co-ordinating a food-security strategy for the nine member-states of the Southern African Development Co-ordination Conference, namely Angola, Botswana, Lesotho, Malawi, Mozambique, Swaziland, Tanzania, Zambia, and Zimbabwe.

Contradictory Evidence

Land use consolidation aims to address food insecurity challenges in Rwanda. However, there is contradictory evidence on whether this tool has met food security objectives or not. This study addresses two questions: How has the land use consolidation improved (or not improved) food security at the local level? How can food security challenges be addressed using a renewed approach to land use consolidation that adopts a tenure responsive land use planning procedure? We investigate these questions in Nyange Sector (in the Musanze District) of Rwanda using mixed research methods. The study generates theoretical and policy relevant outcomes. Theoretically, it links the concept of tenure responsive land-use planning to food security improvements. Policy wise, it provides an operational framework for implementing land use consolidation to make it more responsive to food security (based on tenure responsive land-use planning measures) in Rwanda.

The Impact

With the explosive growth in the world’s population which has little or no corresponding rise in the food production, food insecurity has become eminent, and hence, the need to seek for opportunities to increase food production in order to cater for this population is paramount. The second goal of the Sustainable Development Goals (SDGs) (i.e., ending hunger, achieving food security and improved nutrition, and promoting sustainable agriculture) set by the United Nations (UN) for the year 2030 clearly acknowledged this fact. Improving food production cannot be achieved using the obsolete conventional methods of agriculture by our farmers; hence, this study focuses on developing a model for predicting climatic conditions with a view to reducing their negative impact, and boosting the yield of crop. Temperature, wind, humidity and rainfall were considered as the effect of these factors is more devastating in Nigeria as compared to sun light which is always in abundance. We implemented random forest algorithm using Python programming language to predict the aforementioned climate parameters. The data used was gotten from the Nigerian Meteorological (NiMet) Agency, Lokoja, Kogi State between 1988 and 2018. The result shows that random forest algorithm is effective in climate prediction as the accuracy from the model based on the climatic factors considered was 94.64%. With this, farmers would be able to plan ahead to prevent the impact of the fluctuations in these climatic factors; thus, the yield of crops would be increased. This would dwarf the negative impact of food insecurity to the populace.

Background: Bangladesh is a developing country; so, it is faced with the great challenge of food insecurity. In spite of achieving self-sufficiency in food production, a huge number of people experience the food insecure situation in this country. Since long time ago, scientists are striving to feed the growing population of Bangladesh. However, this study was conducted to assess the present situation of food security in Bangladesh. Methods: This systematic study investigated the available literature and recorded the related and different dimensions of food security in Bangladesh. Results: Bangladesh has made remarkable improvements in food availability, access, and utilization in the last few decades, but it is not the case regarding the food stability. The country experiences numerous challenges regarding food insecurity. Bangladesh has made significant improvement in cereals (rice) production. Despite the increase in the income of people, the food quality is not good. Unequal land ownership and income distribution have made the food access below par. Food utilization has improved but balanced food intake is still far below the standard. A notable portion of people are still severly food insecure and malnourished. To ensure food security, government of Bangladesh has undertaken several programs but they were not sufficient to cope with this everlasting issue. Conclusion: Despite the improvement in many aspects of food security, people of Bangladesh still lack dietary diversification, which leads to nutritional imbalance. In addition, several factors challenge the food security. Therefore, GOs and NGOs should work from the same platform to address the challenges affecting food security in Bangladesh efficiently.

This chapter looks at the challenges presented by hunger and malnutrition. After all, despite significant advances, severe hunger and malnutrition are all too common. Hence, the chapter explains that detailed nutrition and food security surveys can provide valuable information on how to reduce vulnerability and food insecurity. Undoubtedly the most shocking statistic of all is the incidence of child malnutrition, often referred to as “hidden hunger,” which measures the lack of essential micronutrients. This complex challenge involves distinct disciplines and agencies, but in recent years there have been successes by experts in health, nutrition, and agriculture working together over the life of the child to intervene in various ways and at different stages in the child's life. At the same time, Africa is urbanizing rapidly. A steep surge in the growth of the African middle class has taken place, especially in the 2000s. The effect of such an increase is rising urban demand for more and better food, which provides opportunities to increase and diversify food production in rural areas, resulting in greater value capture and rising incomes for smallholder farmers.

<p>Two hundred million persons at an annual population growth rate of 2.5% in addition to uncertainty in climate and societal changes challenges development goals particularly food security in Nigeria. Food security challenges primarily originate from conflicts in agricultural and forestry land systems causing changes in the systems. Agricultural and forestry land systems constitute 77.7% and 7.7% of land area in Nigeria. However, pressured by an increasing population and a changing climate, society and even seemingly divergent policy objectives, these systems have failed to ensure food security. The challenge for Nigeria is to simultaneously maintain a 5% annual increment in food production and conserve 10% of its land area as forest. With agriculture already occupying 77.7% of the total land area, what will a 5% annual increment in food production and a 10% conservation of land area mean for both agriculture and forestry systems? Would these targets require an expansion or intensification or an integration of both systems? This paper provides insights into opportunities and trade-off for optimal land use systems in Nigeria by answering questions such as how can its land use be optimized for biodiversity conservation and agricultural production targets? Amidst the aforementioned targets what plausible governance, management technologies and policy adjustments can aid food security in Nigeria and at what cost?</p>

This article investigates Qatar’s sustainability crisis of the high levels of water, electricity and food use. The high levels of consumption have been enabled by Qatar’s significant hydrocarbons wealth, a generous rentier state’s redistributive water governance, and structural dependence on imported food and food production subsidies. The water crisis is silent because it does not generate supply disruptions nor any public discontentment. The geopolitical blockade Qatar is experiencing sparked discussions in policy circles on the best ways to ensure food security, but has only exacerbated its water insecurity. The blockade makes more urgent than ever the necessity to maximize and increase synergies among different sectors.

Background: Despite significant growth and change in India over the past two decades, some public health indicators have failed to keep pace. One such indicator is food insecurity. India is home to the largest number of people experiencing hunger and food insecurity. Food security is described as “a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life”. While there has been considerable research investigating the role of crop yields, policy interventions, and food production in alleviating food insecurity in India, there is insufficient research investigating the social and cultural influences of food insecurity, including the role of women. The primary aim of this research is to investigate the experience of food insecurity among women in India. The objectives of this research are (1) to determine the role of women in food production and its contribution to household food security; (2) to examine the gender roles within households and the decision-making processes that influence food security, and (3) to investigate household nutritional status and food insecurity experience. Methods: Participants will include women who live in a village in Punjab, India. Interviews with 100 households, drawn from a convenience sample will be conducted. Interviews will be conducted in Punjabi with simultaneous English translation, and will include: food related experiences, anthropometric measurements (weight, height, waist, and hip) and dietary assessment (24-h diet recall, two non-consecutive days), dwelling facilities, agriculture related information, including household agriculture activities undertaken, food security status (via the United States Department of Agriculture Household Food Security Scale Measurement), and demographic information. Discussion: This study aims to investigate a range of determinants of food insecurity among a rural population. It will allow for the identification of some of the components of household food insecurity among women in India and will go part of the way to understanding how and why India continues to experience food and nutritional insecurity despite growth and progress in a range of other indicators.

AbstractObjectiveTo examine the cross-sectional and inter-temporal validity of the Household Food Insecurity Access Scale (HFIAS) for rural households in Burundi.DesignLongitudinal survey about food security and agricultural production, individually administered by trained interviewers in June 2007 and 2012.SettingNgozi, north of Burundi.SubjectsThree hundred and fourteen household heads were interviewed.ResultsTobit models showed that the HFIAS was significantly correlated with objective measures of food security, in this case total annual food production (P<0·01), livestock keeping (P<0·01) and coffee production (P<0·01) in both 2007 and 2012. This confirms that the HFIAS is cross-sectionally valid and corroborates the findings of previous studies. However, while total food production decreased by more than 25 % in terms of energy between 2007 and 2012, households reported an improvement in their perceived food security over the same period, with the HFIAS decreasing from 13·9 to 10·8 (P<0·001). This finding questions the inter-temporal validity of the HFIAS. It may be partly explained through response shifts, in which households assess their own food security status in comparison to that of their peers.ConclusionsThe evidence from our study suggests that the HFIAS is cross-sectionally valid, but may not be inter-temporally valid, and should not be used as a single indicator to study temporal trends in food security.
