Inequalities of opportunity in the access and use of telecommunication services in Togo

The liberalization of the telecommunications sector in Togo aimed at ensuring access to a better quality of telecommunication services at affordable prices to everyone. While the liberalization policy has increased competition in the sector and reduced significantly telecommunication services prices charged to costumers, statistics on the access and use of telecommunication services in Togo reveal disparities with respect to individuals' socio-economic characteristics which could be an indication of the existence of inequalities of opportunities in the access and use of these services.This paper investigates the inequalities of opportunity in the access and use of telecommunication services in Togo using a parametric approach. The results of estimations indicate that, inequalities of opportunities are larger for men and the elderly than respectively women and youths and are more pronounced in urban areas and regions such as the Plateaux and Savanna regions. Moreover, the circumstance variables such as the ‘place of residence’ and the ‘region’ are the key variables in explaining the inequalities of opportunities in the access and use of telecommunication services in Togo. So, policies toward reducing inequalities of opportunity in the access and use of telecommunication services in Togo should be designed with regards to men, the elderly, and people living in urban areas and regions such as the Plateaux and Savanna regions.     

Emerging models of public–private interplay for European broadband access: Evidence from the Netherlands and Italy

The paper examines the role and function of public–private interplay in the development of municipal initiatives in the broadband sector. The analysis of initiatives in the Netherlands and Italy shows how the interaction between public and private stakeholders can facilitate local broadband initiatives. This interaction has been vital in aligning the interests of different private and (semi-)public parties, in designing the network and in aggregating sufficient demand for broadband services. The comparative analysis examines the steps involved in these initiatives and the strengths and weaknesses of joint public–private activities. The paper shows that the challenge for cooperating stakeholders has been to foster further investment in the upgrading of the network and in the provision of advanced broadband services.     

Irrigation,agricultural performance and poverty reduction in China

The overall goal of our paper is to understand the impact that irrigation in China has had on grain production and incomes, in general, and income and poverty alleviation in poor areas, in particular. The paper seeks to meet three objectives. First, we describe the relationship among irrigation status, yields and household crop revenue. Second, we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue. Finally, we seek to understand the impact that irrigation has on incomes in poor areas. Our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas. The importance of crop income in poor areas and the strong relationship between crop revenue and irrigation provides evidence of the importance of irrigation in past and future poverty alleviation in China. We also show that in the majority of the villages that invested in new irrigation, returns are positive even after accounting for increases in capital and production costs.     

Poverty, food security, and nutrition in Central Asia: a case study of the Kyrgyz Republic

This paper attempts to provide insights into poverty, food insecurity, and malnutrition in Central Asia in the period following independence, and presents the available evidence from household-level data in the Kyrgyz Republic. It finds that although some improvement has been made in recent years, significant levels of poverty, food insecurity, and child malnutrition still exist. The paper argues that, in the short run, efforts should be made to protect vulnerable groups by investing in information generation and building capacity to design and implement food security and nutrition policies and programs. Increasing the speed of policy reforms and investment in productivity-enhancing agricultural research and rural infrastructure are fundamental for long-tern sustainable development in Central Asia.     

Was there policy “reform”? Evolution of EU domestic support for processed fruits and vegetables

Policy “reform” in agricultural markets is often associated with less government regulation and expenditures, or a shift towards more efficient interventions. The European Union (EU) adopted major policy changes for processed fruits and vegetables in 2001 and again in 2008, and we employ a simulation model to examine the effects of the three policy regimes in place before and after each of the changes. Our analysis incorporates the heterogeneity of processing firms in the EU and considers how they responded to the different policy regimes. Simulation results indicate that the EU subsidies increased EU tomato production by 3.8% for the regime that began in 2008 and 9.1% for the regime that began in 2001 compared to no subsidies. The policy regime that was in place from 2001 through 2007 led to the greatest distortions in global processing tomato markets, in part because it directed more of the benefits to EU growers and less to EU processors and consumers. Thus changes in 2001 “reformed” policy by redistributing gains within the EU, while changes in 2008 “reformed” policy by reducing distortions in global markets.     

Capacity development in food and nutrition in central and Eastern Europe: A decade of achievements

This article summarizes the activities performed by the Network for Capacity Development in Nutrition in Central and Eastern Europe and Balkan countries (NCDNCEE) in the past decade. The article gives a retrospective of the achievements and challenges in building capacity in nutrition research.Recognizing the lack of capacity and incoherent nutritional situation in CEE/BC, the United Nations University (UNU), Food & Nutrition Programme and the UN Standing Committee on Nutrition (SCN) encouraged the formation of NCDNCEE in 2005, which became CAPNUTRA in 2012.The network’s aim was to initiate and support tailor-made activities for capacity development in food & nutrition in research and training in CEE/BC. To identify the challenges and needs of nutrition research in the region, the network performed inventories on existence of food composition databases, food systems elements, dietary surveys, micronutrient recommendations, application of dietary assessment methods and grey literature. Further on, the network focused on the development of food composition databases and concomitant data management software, the Diet Assess & Plan platform for food consumption collection, dietary intake assessment and nutrition planning. These and other elements form the Balkan Food Platform, which underpins harmonized nutrition research in CEE/BC. Among key actions promoted by the platform are EFSA-supported dietary surveys conducted in four Balkan countries, on children and adults, in which food consumption data are collected and analysed in a harmonized way. Cooperation with FAO and active participation in international research projects enhanced the exchange of information and knowledge and brought international recognition to the CAPNUTRA network.     

Food and nutrition policy in Malta

Food and nutrition policy in Malta was officially endorsed by Government in the late 1980s. The urgency stemmed from the increasingly preoccupying health situation of the Maltese population characterized by the higher rates of cardiovascular diseases and neoplasms. Although a small island in the central Mediterranean, Malta does not have a diet that is characteristic of the rest of the Mediterranean region. The main aim of this paper is to outline the main characteristics of Maltese food consumption and the constraints encountered in the process of implementing the food and nutrition policy. The final section provides some recommendations that could also be considered in other Mediterranean countries that are in the process of designing or implementing similar policies. On the eve of the 21st century and in light of Malta's eventual accession in the European Union, several fundamental measures still need to be introduced and enforced, the most important being those concerning food safety and quality.

The gap not only closes: Resistance and reverse shifts in the digital divide in Russia

The reduction of the digital divide due to the availability of the Internet and the improvement of skills is accompanied by reverse and resistance trends associated with the influence of socio-demographic and economic characteristics of users. In this paper, we estimate the volume and dynamics of the digital divide in access and use of the Internet in Russia by key social groups according to a longitudinal survey for 2008–2018. We found that along with the reducing of the digital divide, its gaps still remain. The greatest polarization is associated with the income, age, and type of residence of the respondents. The most vulnerable social groups on access to ICTs and Internet use are the low-income, the elderly, citizens with disabilities, and those living in rural areas. The reverse shifts in the digital divide were recorded mainly in relation to the Internet usage by age between the middle-age and youth and by gender. In addition, we pointed out the most resistance social groups to reduce the digital divide in the period under review, in particular, by income and type of residence of the respondents. The findings contribute to an understanding of the dynamics and social consequences of the digital divide and can be taken into account in social policy and measures.
