In late 2015, the El Nĩno phenomenon induced Vietnam’s worst drought in 60 years, which lasted until mid-2016 and intensified the most expansive saline intrusion in 90 years. The combination of the two hazards resulted in a large-scale disaster, which has led 18 provinces of Vietnam, most of them from the Mekong Delta, to water shortage, insanitation, human and animal diseases, food emergency need and a considerable disruption in local communities’ livelihoods. These devastating effects raise the question of what makes local households vulnerable to drought and saline intrusion. The chapter argues that vulnerability to the natural disaster is not something resulted from external threats, but rather, is derived from the interplay between social structures residing deeply inside the socio-economic systems and agency’s conditions presenting at the household level. Social structures are rules and procedures that constrain and/or enable human actions in agricultural production, risk taking and adaptation. Agency refers to the capacities of disaster-affected households in the Vietnamese Mekong Delta who cultivated third rice crop and suffered heavily from the 2015–2016 disaster. In addition to households’ lack of planning and coping capacities, the constitution of vulnerability to drought and saline intrusion can be attributed to the interaction between farmers’ choice of extra rice crops and the state’s policies and directions in agricultural and irrigation development since 1990s to date.

This chapter assesses the regional and national approaches to improving food security for rice consumption in West Africa.

Using the Arkansas Global Rice Model and the RICEFLOW frameworks, we examine the consequences of pursuing self-sufficiency in rice. National rice development strategies have been designed to double the 2008 rice production levels by 2018. The Coalition for African Rice Development and the Africa Rice Center have assisted 23 nations in developing national strategies. We evaluate the strategies of 15 nations for rice land expansion and intensification to increase yields for regional self-sufficiency.

West Africa accounts for nearly 25% of global rice imports. The elimination of rice imports reduces global rice prices. Results show that achieving self-sufficiency in West Africa is inefficient at the global level. However, if self-sufficiency makes domestic rice uncompetitive with imported rice, then West African consumers will demand a significant price discount for domestic rice, thus reducing benefits to producers and consumers.

Because of the partial equilibrium nature of this study, the consequences for diversification of West African diets are not explored. Although beyond the scope of this chapter, a coordinated policy sequencing approach toward enhancing productivity and quality of rice production – as well as increasing investment in infrastructure, institutions, and emergency food reserves – should be studied more thoroughly to achieve food and nutritional security for West Africa.

This paper attempts to understand how the interaction of natural disasters and human behaviour during wartime led to famines in three regions under imperial control around the Indian Ocean. The socio-economic structure of these regions had been increasingly differentiated over the period of imperial rule, with large proportions of their populations relying on agricultural labour for their subsistence.

Before the war, food crises in each of the regions had been met by the private importation of grain from national or overseas surplus regions: the grain had been made available through a range of systems, the most complex of which was the Bengal Famine Code in which the able-bodied had to work before receiving money to buy food in the market.

During the Second World War, the loss of control of normal sources of imported grain, the destruction of shipping in the Indian Ocean (by both sides) and the military demands on internal transport systems prevented the use of traditional famine responses when natural events affected grain supply in each of the regions. These circumstances drew the governments into attempts to control their own grain markets.

The food crises raised complex ethical and practical issues for the governments charged with their solution. The most significant of these was that the British Government could have attempted to ship wheat to Bengal but, having lost naval control of the Indian Ocean in 1942 and needing warships in the Atlantic and Mediterranean in 1943 chose to ignore the needs of the people of Bengal, focussing instead on winning the war.

In each of the regions governments allowed/encouraged the balkanisation of the grain supply – at times down to the sub-district level – which at times served to produce waste and corruption, and opened the way for black markets as various groups (inside and outside government ranks) manipulated the local supply.

People were affected in different ways by the changes brought about by the war: some benefitted if their role was important to the war-effort; others suffered. The effect of this was multiplied by the way each government ‘solved’ its financial problems by – in essence – printing money.

Because of the natural events of the period, there would have been food crises in these regions without World War II, but decisions made in the light of wartime exigencies and opportunities turned crises into famines, causing the loss of millions of lives.

On December 31, 2018, the White Earth Reservation Business Committee, or tribal council, passed Resolution Number 001-19-009 recognizing the inherent rights of wild rice. The resolution also includes a regulation entitled “Rights of Manoomin,” meaning the regulation is enforceable under tribal law (White Earth Reservation Business Committee, 2019, pp. 19–21). The Rights of Manoomin lays out the legal protections afforded to wild rice under the resolution. The Reservation Business Committee passed Resolution Number 001-19-010 the same day to support the previous resolution (White Earth Reservation Business Committee, 2019, pp. 22–26). The resolution to recognize the inherent rights of wild rice is part of a larger international movement to recognize the rights of nature (Bouayad, 2020, pp. 39–40). However, the case of the White Earth Anishinaabeg (pl.) and wild rice is different for two reasons. First, the Rights of Manoomin regulation is the first to recognize the inherent rights of a plant (LaDuke, 2019). Second, the resolution claims protection for wild rice in all the territories the Anishinaabeg ceded under the 1867 treaty with the United States government that established the reservation. In this paper, I will argue that the importance of wild rice to the Anishinaabeg and the threats it is currently under served as an impetus for the White Earth Reservation Business Committee to pass the resolutions in question.

The argument for the damaging effects of capitalist modes of production on traditional or indigenous communities is convincing, and has been upheld by scholars interested in development issues. Recent research, however, has called for a closer look at the problem. In this paper, a Japanese village that was created by the government for collective rice farming under a state-controlled distribution system is examined in an attempt to discern how a sudden shift to capitalist modes of production and largely uncontrolled marketing changed the social structure of the community. It is argued that the effects of such a shift may actually promote new unions and different kinds of solidarity, even when the overall impression indicates a decline in solidarity.

This chapter analyzes the economic implications of genetic engineering for food security. We discuss the asynchronous nature of genetically modified (GM) crop regulation and labeling requirements among countries, associated politics, and consumer perceptions of GM crops.

We perform an ex-ante analysis of the introduction of a GM rice variety in major rice exporting and importing countries (including potential producer and consumer impacts) within the framework of a partial equilibrium trade model.

Although the introduction of a GM rice variety that increases global yield by 5% could result in a consumer gain of US$23.4 billion to US$74.8 billion, it could also result in a producer loss of US$9.7 billion to US$63.7 billion. The estimated net gain to society could be US$11.1 billion to US$13.7 billion. Overall, we find a positive economic surplus for major exporters and importers of rice based on a 5% supply increase with a GM rice variety.

The adoption of transgenic (GM) rice varieties would have a far greater impact on rice prices for poorer counties than for richer countries. Therefore, GM rice may help ensure that more people throughout the world would have food security.

To understand the political economy of export restrictions for grain commodities in Vietnam and India.

Two theoretical models were developed (one for each country) to analyze government policies for export restrictions in Vietnam and India based on price fluctuations. In Vietnam, there was one choice variable – export tariffs. In India, there were two choice variables – export tariffs and procurements. In both cases, the elite were assumed to maximize expected rents.

Export restrictions have become an important feature of trade policy in Vietnam and India and are unlikely to be eliminated in the foreseeable future because to do so would be costly both politically and economically to local elites. The impact of food price increases can be particularly large given the importance of loss aversion.

Understanding export restrictions as the outcome of a political-economic calculation is important because it suggests that efforts to limit export restrictions in countries like Vietnam and India are unlikely to be successful.

Purpose – In this study, the possibility of the application of rice husks for adsorbing Mn(II) ion in the water phase has been studied.

Design/Methodology/Approach – Experimental studies have been initiated by preparing activated carbon from rice husks. The activation of rice husks was done using both physical and chemical treatment methods through heating at 110 °C and washing with citric acid activator at 0.2 M, 0.4 M, and 0.6 M. The adsorption tests were conducted as two part tests: preliminary and primary. The preliminary test was conducted to choose the best condition of four independent variables, i.e., contact time (0–120 minutes), activator concentrations (0.2, 0.4, and 0.6 M), initial Mn(II) concentrations (10, 20, 50, 100, 200, and 400 mg/L), and adsorption temperatures (30, 47, and 67 °C).

Findings – By identifying the substituted groups using Fourier Transform Infrared Spectroscopy after activation with citric acid, it was found that the highest transmittance percentage was present in activated carbon with 0.2 M of citric acid. The best adsorption capacity and efficiency was 13.87 mg/g and 79.60%, respectively, which were obtained at 200 mg/L initial concentration with a 0.2 M citric acid concentration for 120 min contact time at 47 °C. These results lead to a conclusion that rice husks after activation with citric acid can be applied as an adsorbent for Mn(II) adsorption in the water phase.

Research Limitations/Implications – The activated carbon produced was only applicable for the adsorption of Mn(II) ions from the water phase, but not applicable for the adsorption of other heavy metals ions.

Practical Implications – Rice husks were potentially prepared as an adsorbent for Mn(II) ion adsorption in the water phase that was low cost, environmental friendly, and easy to prepare.

Originality/Value – Activated carbon prepared from biomass was mostly carried out using acids at high concentrations while the study was conducted using weak acids (citric acid) at low concentrations.

Since 1997, a quantitative revolution has swept Korean economic history and generated a new paradigm. From 1700 to 1900 the Korean economy expanded and contracted along lines suggested by Adam Smith. Economic expansion was based on productive land and a stable commodity market. The direct result was high real skilled wages. Economic contraction became clear from the mid-nineteenth century when the value of land declined, commodity prices rose, and real skilled wages fell. The contraction was apparent before the appearance of Japanese imperialism and the absorption of Korea into the international commodity market after 1876.

During the last decade or so, philosophers of science have shown increasing interest in scientific models and modeling. The primary impetus seems to have come from the philosophy of biology, but increasingly the philosophy of economics has been drawn into the discussion. This paper will focus on the particular subset of this literature that emphasizes the difference between a scientific model being explanatory and one that provides explanations of specific events. The main differences are in the structure of the models and the characteristics of the explanatory target. Traditionally, scientific explanations have been framed in terms of explaining particular events, but many scientific models have targets that are hypothetical patterns: “patterns of macroscopic behavior across systems that are heterogeneous at smaller scales” (Batterman & Rice, 2014, p. 349). The models with this characteristic are often highly idealized, and have complex and heterogeneous targets; such models are “central to a kind of modeling that is widely used in biology and economics” (Rohwer & Rice, 2013, p. 335). This paper has three main goals: (i) to discuss the literature on such models in the philosophy of biology, (ii) to show that certain economic phenomena possess the same degree of heterogeneity and complexity often encountered in biology (and thus, that hypothetical pattern explanations may be appropriate in certain areas of economics), and (iii) to demonstrate that Hayek’s arguments about “pattern predictions” and “explanations of the principle” are essentially arguments for the importance of this type of modeling in economics.
