After a 16-m high dam was constructed and a 297-ha pond was arranged in the River Šušvė nearby Angiriai in 1980, the previous natural flow regime of the river has changed: 15500000 m3 of water accumulated above the dam is not discharged via a natural bed, but through two 1.5x1.5 m bottom orifices, and flood discharges (up to Q1% = 296 m3 sE-1) are directed into the lower reach through a 16-m high shaft spillway of floods. Such arrangement of the Angiriai dam ensured it to become an essential obstacle for migrating fish. In 2000, after the arrangement and operation of Angiriai hydro-electric power station, the water regime downstream the dam has been changed and new hydrological pulses as well as ecosystem biodiversity are to be adapted. Thus, the operation of Angiriai HPS on the River Šušvė generating hydroelectric power can have adverse effect on the river habitats and hydro ecological connectivity. To evaluate the effect, the eco-hydraulic water regime measurements in 2005 in a lower stretch with and without turbines operating were made. The study results showed that artificial water levels fluctuation (≈ 4 m hrE-1) induced by Angiriai hydro-electric power station as well as the discharge flowing through the bottom orifices due to high velocities (13–14 m sE-1) and temperature differences could create stressful situations for young fish in the lower bank. According to the data of soil texture of the Šušvė River, the bed armoring process is going on below the Angiriai HPS is quasistable and no impact of HPS operation is found.

The aim of the study is to analyse society's attitude towards globalization, increased immigration and multicultural dialogue emphasizing the importance of multicultural education. The investigation is based on the EU Comenius school partnership project 'Richness in Diversity' (No.: 07-LVA 01-CO 06-00167-2) where five EU countries (Latvia, Slovakia, Portugal, the Netherlands and Ireland) are involved. During investigation, a qualitative research has been done. The EU Comenius school partnership project 'Richness in Diversity' coordinators (teachers experts) were interviewed to discover their own experience and attitude towards globalization, migration, intercultural dialogue as well as their observations of their students' (aged 12-15) attitude and knowledge at the beginning of the project and dynamics - how changes their attitude when they have a possibility to visit a particular country and meet its inhabitants. The results show a positive progress of the teachers' and students' knowledge about the EU Comenius school partnership project 'Richness in Diversity' involved countries. During the project, mobilities students live in host families which give them an excellent opportunity to get introduced with the particular EU country's family, their everyday life, traditions and habits. It helps them better understand people from different cultures and learn to appreciate the culture diversity.

Nowadays the need for a qualitative, accessible and varied lifelong learning is becoming more and more necessary. In Latvia, different institutions take part in the implementation of lifelong learning; however, in spite of the negative factors of demography and migration, changes of work force supply and demand, investment and information shortage, the role of universities has not been properly investigated. The role of higher education in lifelong learning was studied in 9 state universities of Latvia in the period of 2013 – 2015. Monographic analysis and method of synthesis, data statistical research methods – grouping, comparison, relative and average indicators, as well as dynamics line analysis was used in the article. The study proved that the number of occupied work places has increased in 2015. However, it has not reached the average of ten and seven years since 2006 and 2009. Comparing with the free vacancies, the number of them has increased by 2164, especially in the profession group specialists and senior specialists, which as well as executives, is the target audience of universities, which in its turn is a lifelong learning event insufficiently used potential. The universities have suffered because of demographic and migration factors: the rate of student number increases (-9.4%). In order to reach the goals of education politics, universities try to direct education function from studies to lifelong learning; they try to improve existing lifelong learning courses and programs, as well as to propose new ones in order to offer something for workforce corrections.

Salmon (Salmo salar L.) is grown and released in the estuaries in Latvia from which it goes to the feeding areas in the Baltic Sea. The research summaries data about clinical characteristics of fin necrosis and its prevalence in Latvian hatcheries before the smolt stage (complicated physiological, biochemical and morphophysiological changes resulting in migration flight). Clinically expressed fin necrosis was observed in 92.7-97.4% cases.

The chapter examines whether contract farming confers benefits primarily to large farmers in practice and how we may be able to make smallholders significantly better off by introducing new profitable crops and livestock products. More often than not, agriculture does not provide ample employment opportunities, largely due to land constraints on production expansion. One solution is to develop nonfarm sectors so as to provide more lucrative employment opportunities, in which working members of farm households increasingly find jobs. The chapter demonstrates the critical importance of increasing nonfarm income to improve the income of rural households and examines the roles of infrastructure and human capital in raising nonfarm income.

This report offers specific policy and investment options articulated around two broad areas: (1) stimulating growth in agriculture and sustainable management of fisheries and (2) providing public infrastructure and services that strengthen the enabling environment. A plan to stimulate growth in agriculture and fisheries, the first broad area, could be centered around the following set of goals: revitalize the rubber sector, develop high-value fresh products, improve rice productivity, modernize land and input markets, expand access to loans for machinery and seasonal input purchases, strengthen agricultural extension services to ensure dynamism in Mon State’s farm sector, improve management of marine capture fisheries, and facilitate expansion of aquaculture. The first part of the report details the challenges and potential solutions presented by each of these points. The second part of the report details options to create a growth-enabling environment through public infrastructure and services, centered around the following goals: improve the budgetary and fiscal process to enable locally driven public investment, improve access to and reliability of infrastructure, expand the formal credit market, promote productive investment by the private sector, strengthen regulatory frameworks for the construction sector, exploit the potential for the development of tourism, and improve the quality of and access to education and health services.

Central Asia faces substantial water scarcity due to increasing water demand driven by rapid urbanization, population growth, economic development, and inefficiency of irrigated agriculture. These developments are compounded by the effects of climate change, such as rising temperatures, loss of glacier mass and increased frequency of extreme events, including droughts. The region’s escalating water scarcity is causing disputes and straining rural livelihoods. Moreover, these challenges drive migration, creating considerable societal impacts. However, these issues remain underexplored in climate change research, making the region a global blind spot in climate adaptation and migration studies. We advocate for innovative research pathways that scrutinize smallholder adaptation strategies, examine the nexus between climate change, water scarcity, and mobility, and investigate tensions and cooperation over water resources. We conclude by emphasizing that substantial investments in inter- and transdisciplinary collaboration, improved data availability and quality, and strengthening of research and institutional capacities are essential to advance interdisciplinary climate impact research in Central Asia. Such efforts are vital for addressing existing knowledge gaps and enhancing evidence-based policymaking to improve the region’s position in current and future debates on climate change and sustainable development.
