Soybean is the third important food crop in Indonesia after rice and maize, particularly as a good source of protein. The demand for soybean consumption tends to increase annually. In 2020, the figure was about 3.28 million tons, while the domestic production was 0.63 million tons, thus around 81% of the soybean needed was imported. Efforts to increase the domestic soybean production have been conducted since the last decade, which is concerned with increasing the current productivity (1.5 t/ha) through introducing the high-yielding improved varieties and extending the harvested area, particularly to outside of Java. The potential planting area is focused on the irrigated lowland after rice (optimal land) and suboptimal lands (dry, acid, tidal, and shaded lands). The series of the study showed that the yield potential of soybean grown in such lands varied from 1.8 t/ha to 3.0 t/ha. A number of soybeans improved varieties adapted to different land types or agro-ecological conditions also have been released and supported with advanced cultivation technology. The results, challenges, and opportunities to achieve soybean self-sufficiency are discussed in this paper.

District Heating Systems

The current situation in the sphere of district heating is analysed on the basis of use of the cognitive approach. The presence of closed chains of cause-effect relationships of negative factors and conflicts of target settings of the subjects in the field of district heating is shown. The conceptual model of energy efficient modernization of district heating systems is proposed. This model includes indicators of the current status of heat sources, networks and heat consumers, energetic and economic models, restrictions, procedure of forming and analysis of the mutual influence of the recommended projects. The quantitative data on indicators of the current state of district heating systems of the cities of Ukraine are presented. The interrelation between indicators of the current state and projects of energy efficient modernization of district heating systems is shown. Assessment of energy self-sufficiency of municipal district heating systems on condition of thermal modernization of buildings is carried out. The creation of energy management systems at the district heating enterprises is proposed. Bib. 6, Fig. 7, Tab. 5.

AbstractPotato is the third most important staple food crop. To address challenges associated with global food security, a hybrid potato breeding system, aimed at converting potato from a tuber-propagated tetraploid crop into a seed-propagated diploid crop through crossing inbred lines, is under development. However, given that most diploid potatoes are self-incompatible, this represents a major obstacle which needs to be addressed in order to develop inbred lines. Here, we report on a self-compatible diploid potato, RH89-039-16 (RH), which can efficiently induce a mating transition from self-incompatibility to self-compatibility, when crossed to self-incompatible lines. We identify the S-locusinhibitor (Sli) gene in RH, capable of interacting with multiple allelic variants of the pistil-specific S-ribonucleases (S-RNases). Further, Sli gene functions like a general S-RNase inhibitor, to impart SC to RH and other self-incompatible potatoes. Discovery of Sli now offers a path forward for the diploid hybrid breeding program.

Policy-makers in many nations of the world are involved in educational reforms. In order to make effective educational decisions for the 21st century, policy-makers need information of a wide variety of kinds, for example, comparative performance data and curriculum information from other nations. National assessments can be valuable, but international surveys provide a broader base of information and allow countries to view their current status and planning within an international perspective. The purpose of this paper is to describe the goals of the Third International Mathematics and Science Study and the steps being followed to insure that the results from the study will meet the diverse informational needs of policy-makers.

Challenges And Opportunities

Africa faces difficult water/sanitation legacies in the form of high hydrological variability and a multiplicity of transboundary river basins alongside poor sanitation. These challenges impeded the continent’s economic growth. Balanced investments in water resource and sanitation infrastructure and institutions are needed to increase productive uses of water, to mitigate the effect of recurrent floods and droughts, and to achieve basic water security as a platform for Africa’s economic growth. Priority should be given to investments that (a) focus on growth, (b) reduce rural poverty, (c) build climate resilience and adaptation, and (d) foster cooperation in international river basins. Because most African countries have low stocks of hydraulic infrastructure, emphasizing investments in infrastructure is appropriate for them. However, institution building and reform, improvements in water/sanitation management and operations, and strengthening of water information systems must complement growth in infrastructure. Development of institutions should be advanced in parallel with infrastructure investment.
