In so doing, this paper analyzes differences and similarities in Soviet penetration to lands with newly established governments in Africa and Cuba. JEL Classification: N60, N67, N97.

INTRODUCTION 1. The present report is submitted to the Executive Committee (EXCOM) for information. EXCOM requested the Secretariat to prepare an annual report on evaluation at the ninety-first Meeting on 24 March 20171, beginning with an annual report for 2017. The purpose of the report is to inform the UNECE member States on evaluation efforts conducted during the past year, future evaluation plans, the status and information on completed, ongoing evaluations, and changes generated by the implementation of relevant recommendations. 2. As per the UNECE Evaluation Policy, the Secretariat undertakes evaluations for the purpose of learning, as well as to improve the future work of the organization. The present report consolidates and analyses the outcome of all evaluations conducted in 2020 to support this objective. The Executive Secretary, through the Programme Management Unit (PMU), ensures the consistent application of evaluation norms and standards across UNECE, and ensures the application of the key outcomes of evaluations into the future planning of the UNECE programme of work. 3. The analysis is based on the results of all evaluations conducted and/or commissioned by UNECE, relevant external and/or system-wide evaluations, and the UN System Wide Action Plan (UN-SWAP) to implement the Chief Executives Board for Coordination (CEB) Policy on gender 2 equality and the empowerment of women. 2.

  • Informal Document No.2 Agenda Item 6 (C) Presented by Belarus
    Informal document No.2 Agenda item 6 (c) Presented by Belarus Summary report on establishment of “the Daugava - Dnieper waterway link and, as an option, its connection to the White Sea Nowadays there’s sustainable tendency in the world economy to share the labour and to be specialised in certain fields of production. Under such circumstances special attention is paid to the transport. Its basic mission is to fill geographic gap between the sources of mineral resources, industries and their consumers, for the supplier and the customer could exchange goods and services to mutual benefit. Economic growth after the WW II has facilitated development of transport and in particular of the rail and road ones. It resulted in overloading of European countries with means of transport which negatively affect ecology. Due to this growth the development of alternative to the road and rail transport is getting urgent. At recent European forums it was stressed that priority should be given to inland shipping because of its ecological and economic advantages over other types of transport and due to overloading of European transport infrastructure. The tasks which have been set forth by them could be solved in two ways that is by increasing traffic capacity of existing European infrastructure and by creating new transit waterways. Based on the study of cargo flows the priority should be given to transit waterways which would link the Baltic and the Black Seas. There are various options of the link. In the file attached to this report there are comparison data on the Pripyat-the Nieman and the Dnieper - the Dvina options of the waterway.

  • Aswan Dam Construction History Aswan Low
    Aswan Dam The Aswan Dam may refer to either of two dams situated across the Nile River in Aswan, Egypt. Since the 1950s, the name commonly refers to the High Dam, which is the larger and newer of the two. The Old Aswan Dam, or Aswan Low Dam, was first completed in 1902 and then was raised twice, during the British colonial period. Following Egypt's independence from the United Kingdom, the High Dam was constructed between 1960 and 1970. Both projects aimed to increase economic production by regulating the annual riverflooding and providing storage of water for agriculture, and later, to generate hydroelectricity. Both have had significant impact on theeconomy and culture of Egypt. The Old Aswan Dam was built at the former first cataract of the Nile, and is located about 1000 km up-river and 690 km (direct distance) south- southeast of Cairo. The newer Aswan High Dam is located 7.3 km upriver from the older dam. Before the dams were built, the River Nile flooded each year during late summer, as water flowed down the valley from its East Africandrainage basin. These floods brought high water and natural nutrients and minerals that annually enriched the fertile soil along thefloodplain and delta; this made the Nile valley ideal for farming since ancient times. Because floods vary, in high-water years, the wholecrop might be wiped out, while in low-water years widespread drought and famine occasionally occurred. As Egypt's population grew and conditions changed, both a desire and ability developed to control the floods, and thus both protect and support farmland and the economically important cotton crop.
