During the last five years the scientific knowledge on insects as food and feed has been growing exponentially. At the same time, the industrial sector is increasingly engaged in rearing, processing and marketing of edible insects. Considerable attention is given to the black soldier fly as it can convert organic waste streams and transform it into several feed, food and industrial products. The farming of insects has an environmental impact which is lower than that of livestock species. The profitability of industrial production of insects as feed depends very much on the availability and applicability of cheap non-utilised side-streams. Microbial communities and their relationship with insects deserve full attention as it may help in the conversion of organic side streams of low economic value. Nutrition and health benefits for animals and humans need further exploration, also considering that insects have the largest anti-microbial peptide reservoir of all animals. Plant health can also be promoted by using chitin-containing leftover substrates as fertiliser. As insects have only recently been considered as food or feed, legislation trails developments. Therefore, politicians need to be assured that rearing and processing techniques are such that insect products are guaranteed free of chemical and microbial contaminants. Consumers are becoming more and more aware that insects as food are a viable option. Insects need to be processed into ingredients, that can be applied for safe and appetising products. The insect sector is maturing fast, but still faces many challenges, which can only be met when all stakeholders closely cooperate.

Edible insects are natural resources that provide foodstuff to numerous ethnic groups in rural India. In spite of the dietary and ecological repayment, the consumption of insects is still restricted to a limited number of countries globally. Apart from the establishment of consumer acceptance, research is necessary to develop sophisticated and automatise cost-effective production of insect products. Insects have massive prospects as feed. As the protein feed ingredients are becoming expensive, several studies are in progress to establish insects as feed in the Indian market. Insect food and feed industry could be a proficient approach to consign the cost of living for the price-sensitive customers. Cross-linking between the industries and the farmers would be helpful for boosting the production rate of insect products. Extensive and systematic study of the edible insects would be desirable to ascertain food security and elude possible risks.

Carboxylate Platform

The notion of a “biobased economy” in the context of a developing country such as South Africa (SA) necessitates the development of technologies that utilize sustainable feedstocks, have simple and robust operations, are feasible at small scale and produce a variety of valuable bioproducts, thus fitting the biorefinery concept. This case study focuses on the microbial production of higher-value products from selected organic waste streams abundant in the South African agricultural sector using microbes adapted to utilize different parts of biomass waste streams. A ruminant-based carboxylate platform based on mixed or undefined anaerobic co-cultures of rumen microorganisms can convert the carbohydrate polymers in the lignocellulosic part of organic waste streams to carboxylic acids that can be upgraded to biofuels or green chemicals. Furthermore, yeast and fungi can convert the simpler carbohydrates (such as the sugars and malic acid in grape and apple pomace) to ethanol and high-value carboxylic acids, such as lactic, fumaric, succinic and citric acid. This review will discuss the combinational use of the ruminal carboxylate platform and native or recombinant yeasts to valorize biomass waste streams through the production of higher-value organic acids with various applications.

Two Sectors

This note is an extension of several contributions to the problem of re¬source allocation in a developing economy. In separate papers, I.M.D. Little and F. Seton* have introduced a model in which labour in a developing economy cannot be shifted from the subsistence to the industrial sector at zero opportunity cost, even though this labour displays zero marginal product in its 'traditional' occupations; and in what follows this problem will be attacked via a diagramma¬tic analysis. A short appendix will treat a side issue of the topic. As Little presented the model, there was an initial amount of capital K to be divided between two sectors, the I (industrial) sector, and the C (subsistence, traditional, or agricultural) sector. In the C-sector, there is excess labour or dis¬guised unemployment, in the sense of Professor W. A. Lewis2, in that the marginal product of labour in this sector is taken as equal to zero. As it happens, however, this labour cannot be moved to the I-Sector without an increase in production in the C-sector. The reason for this is because as labour is transferred to the industrial sector, consumption per head increases in the C-sector, thus decreasing the surplus available for workers being transferred to the I-sector. The transfer can only be carried out if a surplus equal to the difference between the industrial wage in C-goods and the amount of C-goods 'released' by the C-sector is forth¬coming, and for this an increased production of C-goods (via the input of capital into the C-sector) must take place. A similar situation would exist if transferring workers required a wage differential; or if C-goods had to be exported to obtain certain types of capital goods for the labour being reallocated, and/or housing, training, etc.

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

Emerging Market Countries

This article analyzes the structural transformation in 30 emerging market countries (E30) on the dimensions of industry, trade, and urbanization. It finds that first, in the agricultural sector, E30 have contributed greatly to the increase of the global agricultural productivity and the transfer of labor force from the agricultural sector to industry or the service sector. However, these countries still feature a high percentage of agricultural employment, which means there is vast room for shifting the agricultural labor force. Second, in the industrial sector, E30 have made remarkable contributions to the world’s industrial development but have also displayed a trend of premature “deindustrialization.” Third, the service sector has picked up speed and gradually turned into a new driver of economic development in E30. Against this backdrop, E30 face the major challenge of how to cope with the premature deindustrialization and smoothly shift the economic growth engine from the industrial sector to the service sector. Fourth, E30 have become an important force in the world trade, with their trade structure switching from simple, primary, low-value-added goods to sophisticated, high-grade, and high-value-added goods and services. However, some emerging market countries are more susceptible to the impacts of the anti-globalization trend because of their high reliance on foreign trade and improper trade structure. Therefore, how to diversify the economy and enhance its economic resilience holds the key to the sustainable economic development of E30. Fifth, E30 have contributed greatly to world urbanization. As urbanization relies more on the service sector than on the industrial sector, it is vital to properly strike a balance between industrialization and urbanization, and between industrialization and service sector development.

Effects Of Drought

Abstract A decision framework is developed for quantifying the economic value of information (VOI) from the Gravity Recovery and Climate Experiment (GRACE) satellite mission for drought monitoring, with a focus on the potential contributions of groundwater storage and soil moisture measurements from the GRACE data assimilation (GRACE-DA) system. The study consists of (i) the development of a conceptual framework to evaluate the socioeconomic value of GRACE-DA as a contributing source of information to drought monitoring; (ii) structured listening sessions to understand the needs of stakeholders who are affected by drought monitoring; (iii) econometric analysis based on the conceptual framework that characterizes the contribution of GRACE-DA to the U.S. Drought Monitor (USDM) in capturing the effects of drought on the agricultural sector; and (iv) a demonstration of how the improved characterization of drought conditions may influence decisions made in a real-world drought disaster assistance program. Results show that GRACE-DA has the potential to lower the uncertainty associated with the understanding of drought and that this improved understanding has the potential to change policy decisions that lead to tangible societal benefits.
