Purpose- Among the most important challenges in the agricultural sector are lack of optimal use of production factors, multiplicity of parcels and dispersion of agricultural lands. Land consolidation is one of the effective solutions which can change the size of fields and organize them to increase production, especially in paddy fields, which facilities agricultural development and ultimately achieves a sustainable livelihood in rural areas. The purpose of this study is to evaluate the success rate of paddy field consolidation project through the study of a group of farmers who are included in the land consolidation project. Design/Method/Approach- The population of the study consisted of 285 farmers from 11 villages of Choobar rural district in Shaft County who have been selected by regular sampling method. To collect the data, library and survey methods (observation and questionnaires) have been used. Cronbach's alpha was used to measure the reliability of the research tools, and in the analytical part, single-sample t-test was used to evaluate the success rate of the project in Choobar rural district; To investigate the relationship between land consolidation project and improvement in economic indicators of rural households, initially Spearman correlation coefficient was used, then simple regression test and coefficient of determination R2 were used to measure the effectiveness of the project on economic indicators. Finding- The research findings on the level of economic and social dimensions and the assessment of the success rate of the project in Choobar rural district showed the project was moderately to highly successful in the study area. The effects of the project in improving the socio-economic indicators of rural households in Choobar rural district are such that the highest correlations were found between the project and economic indicators in the use of machinery, land infrastructure, productivity, household employment, ease of access to machinery and manpower, income, and investment; At the level of social indicators the highest correlations were respectively found in interpersonal and generalized trust, objective participation, sense of physical security, insurance services, formal participation, conflict reduction and institutional trust. From farmers’ perspective, among the socio-economic indicators, the infrastructure indicator which is created by the government and the use of machinery after the implementation of the project, and the ease of access to machinery and manpower, interpersonal and generalized trust have had the greatest impact on the implementation of the project.

South Africa is a water-scarce country that is highly dependent on agriculture. This means that the local impacts of climate altering phenomenon, such as the El Niño-Southern Oscillation (ENSO), are critical to understand. At a broad scale, these systems are known to affect rainfall distribution, resulting in drought (flood) conditions during El Niño (La Niña) events in the majority of the country, and the converse in the southwestern Cape. However, fine resolution analyses of local impacts of these events have been restricted to the coastal zone, and little is known for the interior. We explore the uniformity in the transition of the climatic deviations [for minimum temperature (T_min) and maximum temperature (T_max), and rainfall] along a 12-site transect spanning the South African interior. The majority of the deviations determined were not statistically significant which suggests that the common understanding of the climatic impacts of ENSO events in South Africa is not well understood. However, it should be acknowledged that all the locations used in this research, aside from Hermanus, were located inland which may be the reason the deviations at these locations were not statistically significant.

One of the issues discussed in geopolitics is the role of international straits (canals); as such, it is of great importance to investigate their geopolitical and strategic role. It is because the straits are the places of distribution of power, where the competition of governments is very evident in using the potential of geographic space to achieve greater benefits and ultimately to gain power in international relations. Even in some cases, countries not located around the straits enter many ways in order not to lag behind other countries. That is to say, there is a kind of conflict and competition between countries over the use of straits, especially the countries bordering the strait. Therefore, the strategic straits play a decisive role in the power of nations and their fate and also in the foreign policy of the coastal states along with the balance of regional and global power, as a result, their study is essential for political geographers and geopoliticians. One of the most important straits in the world is the Malacca Strait whose investigation strategically and geographically provides important points. Using descriptive-analytical method and also based on statistics and figures for plotting diagrams in this paper, it has been tried to study the role, geopolitical features, and importance of Malacca Strait for coastal states and conditions as well as factors causing challenges and crises for the strategic role of the strait. According to the results, as one of the major international straits, the Malacca Strait has strategic potentials in the regional and global arena and coastal governments need to rely on targeted and strategic plans to combat the challenging processes in this strait<strong>.</strong>
