Published: November 2021

Abstract
The COVID-19 pandemic comprises a “milestone” for multiple aspects of social, economic, and technological life. Trips and movements were placed at the center of attention to control the virus’ transmission since the diffusion may occur both during the trip, while people are on-board, and after they arrive at the final destination, in the context of their activities. Public Transport Authorities (PTA), providers of mobility services, and commuters have faced various challenges that require from them a change or adaptation of their practices and behavior. In the framework of the European project “PE4Trans”, which concerns citizens’ engagement in the planning of sustainable mobility policies, a multidisciplinary three-session virtual event took place. Its aim was to address all challenges posed by the pandemic related to mobility and transport by involving researchers, executive officers, decision-makers, and policymakers in an organized dialogue. This paper systematizes and synthesizes the findings of this discussion, covering aspects related to the nature of the pandemic, the measures of personal protection along the whole mobility chain, the structural business changes for the case of mobility providers, the exploitation of technology, the people with disability, and the role of the local authorities. The pandemic reveals itself as a two-sided coin: its first side is related to the public health crisis that needs proper handling within the transport system, while its second side is related to the chance of accelerating the transition towards sustainable mobility and the opportunity of promoting reforms within the transport business sector.

Abstract
The objective of this study stands for the investigation and evaluation of accidents that take place on highways, in comparison with speed limits. The main body of this research is based on the collection of highways speed limits from different countries around the globe regarding to years, 2010, 2017 and 2018. Secondly, accident rates are collected from highway authorities, as well as from international literature. Subsequently, a statistical analysis of the collected data is conducted and finally leads to an equation that links and correlates the speed limit values and the number of accidents. The results of this statistical analysis show that speed limit plays a certain and distinctive role in the accident rate value. However, one of the interesting findings, stands for the non-continuously increasing number of accidents in the speed limit range, from the lowest to the highest value, meaning that there is an inflection point in the graph of the correlation equation. To be noted, that in terms of this study, the aforementioned correlation is independent of other factors that could affect the accident rate, such as vehicles condition, technology, road network length and condition.

Abstract
The Greek economic crisis of 2009 onwards has affected all aspects of social and economic life of the country, including transportation. Taking into account the link between the economic crisis and transportation, the present study aims to investigate the way that the economic crisis has affected the interurban travel rail habits of the citizens of Athens, the capital of Greece. We conducted a study, using a questionnaire survey with 400 participants, to investigate the general trends concerning the purpose and the frequency of railway travelling and the restrictions of their travel activities due to the economic recession. The results of this study show that more than half of respondents declared that there is not any great difference in their use of rail as transport during last years, while they express a positive opinion as they attribute it to the higher safety and comfort of railway compared to other transportation modes. However, the cost of the ticket and the provided level of service are two significant factors for the participants for the choice of their transportation mode.

Abstract
Submergence by flooding caused damage in rice growing areas and huge economic loss, and developing tolerant varieties is considered as the best approach to overcome the problem. Markers Assisted Backcrossing (MABC) approach is widely to develop Sub-1 tolerant varieties. The availability of polymorphic markers is among the most crucial requirement to implement the MABC method. This research was subjected to assess DNA polymorphism between IR64Sub1 and tree Indonesian popular varieties. A total of 136 microsatellites/simple sequence repeat markers were used to genotype tree Indonesian popular varieties; Cisantana, Angke and Mekongga and IR64-Sub1. A total of 39 markers covering 11 chromosomes were found polymorphic between IR64 Sub-1 and the three varieties, however no polymorphic markers found in chromosome 12. The lack polymorphic markers were also found in chromosome 10 and 11 between IR64 Sub 1 and Angke. With the completion of the missing markers, these 39 polymorphic SSR markers can be utilized to support the MABC program for the development of new Sub-1 tolerant variety with multiple tolerances.

Abstract
The use of pod-shatter resistant variety is considered effective in reducing yield loss in soybeans. This study aimed to identify and grouping of pod shattering resistance and agronomic characters performance from several advanced soybean lines. The field experiment was conducted in Blitar (Indonesia) from January to April 2021, using 20 soybean advanced lines and two check cultivars. The laboratory study to identify the pod shattering resistance based on the oven-dry method was conducted in the Breeding Laboratory of ILETRI, Malang. The pod shattering resistance of 20 advanced lines was classified into five very resistant genotypes, three resistant genotypes, two moderate genotypes, nine susceptible genotypes, and a very susceptible genotype. The pod shattering resistance has a significant negative correlation with the pod width (r = -0.472*). A wider pod resulted in a low percentage of shattering. The agronomic performance varied among all genotypes. Selection for pod shattering resistance and agronomic performance obtained two lines (G511H/Anjas//Anjas///Anjas-3-1 and Dega/Degra-2-105) as high yielding and very resistant to pod shattering. Those lines were suggested to be tested across diverse environments to determine their yield potential and stability.

Abstract
The success of a product is whether the product or technology is accepted by the user/consumer. To bridge the gap between breeders and farmers and to ensure that new varieties satisfy farmers’ preferences and suitable to the its socioeconomic situations, a study of farmers’ preference is needed. Therefore the study aims to know the preference and the feasibility of the composite corn in Central Sulawesi. The introduction composite corn consist of Srikandi Kuning, Lamuru, Sukmaraga, and Anoman which were applied in Kaji Terap Program. A survey had been conducted to users in Parigi Moutong and Sigi District Central Sulawesi, and a quantitative and descriptive analysis approach were employed in this study. Proportion analysis was used to measure the general perferences of farmers as user while the detail perception was calculated using scoring method. The findings show that more than 50% users in dry land have high preference to composite corn for some characteristics namely: productivity, drought, diseases resistant, grain color, market preferences, and number of corncob. Anoman which has high productivity but has lower preference because of its color does not suit with the market’ preference.

Authors: Nakamo S J 
Published: November 2021

Abstract
It has known that grain production is declining globally, leading to food insecurity becoming increasingly apparent in tropical countries, particularly in Sub-Saharan Africa. Countries in Sub-Saharan Africa must concentrate on indigenous agricultural methods to mitigate the impact of climate change on grain production while preserving ecological balances and achieving sustainable goals. Matengo/Ngolo pits, practised on steep slopes in the Matengo highlands, southern Tanzania, are indigenous knowledge invented by local communities over the past 300 years. Despite its effectiveness in increasing agricultural productivity, soil moisture retention, and other environmental advantages, Matengo/Ngolo agricultural technique has resulted in severe land cover changes that substantially influence other producing sectors. Understanding the agro-ecological zones is essential for enhancing policy development for the expansion and restrictive of Matengo/Ngolo pits practice that intercepting by decreasing its influence on the shrinkage of other ecological services, achieving sustainable agricultural practice in the Matengo highlands. Therefore, this study employed the multi-criteria parameters under the fuzzy logic algorithm in ArcGIS 10.8 for modelling the Matengo/Ngolo pits agro-ecological zone to realize sustainable land management in Matengo highlands.
