Abstract:
While Asian and European countries were grappling with the Covid-19 pandemic, the first imported case from the United Kingdom surfaced in Jamaica on 10 March 2020. The article will trace the steps taken by the National Library of Jamaica (NLJ) before and during the pandemic while improving the value of our cultural heritage to Jamaica and the wider diaspora. The NLJ celebrated 40 years of sterling contribution to the development of Jamaica from March 1979 to April 2020. It has been a leading voice in the region in disaster management and preparedness. Through its Preservation and Conservation Branch, and oversight from the Disaster Preparedness Committee, the NLJ has become a training ground for professionals in the information and conservation field. While highlighting the work of the NLJ, the article will also present statements and surveys conducted on regional and international bodies. These organisations include the Association of Caribbean University, Research and Institutional Libraries (ACURIL), the Community of Directors of National Libraries (a subgroup of the International Federation of Library Associations (IFLA) and the Society of American Archivists. The surveys conducted gleaned a greater appreciation of the impact of Covid-19 on libraries and archives regionally and internationally. The article will address other pandemic crises that have affected Jamaica. It will also demonstrate that being proactive and prepared for viral episodes can mitigate the risks. The NLJ used the opportunity to facilitate service delivery while being socially distant from its patrons.

Abstract:
This paper reviews Ethiopia’s experience and research progress in past soil and water conservation (SWC) efforts and suggests possible solutions for improvement. Although indigenous SWC techniques date back to 400 BC, institutionalized SWC activity in Ethiopia became significant only after the 1970s. At least six national SWC-related programs have been initiated since the 1970s and their focus over time has shifted from food relief to land conservation and then to livelihoods. The overall current soil erosion rates are highly variable and large by international standards, and sheet, rill, and gully erosion are the dominant processes. The influence of human activities on the landscape has traditionally been deleterious, but this trend seems to have recently reversed in some parts of the country following the engagement of the communities in land management. The efficiency of SWC measures show mixed results that are influenced by the type of measures and the agro-ecology under which they were implemented; in general, the relative performance of the interventions is better in the drylands as compared with humid areas. Methodological limitations also occur when addressing the economic aspects related to benefits of ecosystem services and other externalities. Although farmers have shown an increased understanding of the soil erosion problem, SWC efforts face a host of barriers related to limited access to capital, limited benefits, land tenure insecurity, limited technology choices and technical support, and poor community participation. In general SWC research in Ethiopia is fragmented and not comprehensive, mainly because of a lack of participatory research, field observations, and adoptable methods to evaluate impacts. A potentially feasible approach to expand and sustain SWC programs is to attract benefits from global carbon markets. Moreover, a dedicated institution responsible for overseeing the research–extension linkage of SWC interventions of the country should be established.

Abstract:
Soil erosion and socio-economic interacts with each other. Soil and water loss destroys land resources, causes non-point source pollution, affects the recycling and utilization of water resources, worsens the water environment, and even causes natural disasters such as collapse, landslides, and debris flows. Soil erosion affects regional socio-economic development. On the one hand, economic and social development has caused a sharp increase in people’s demand for the development and utilization of natural resources, which has increased the occurrence of soil and water loss; on the other hand, economic and social development has promoted people’s understanding of soil erosion and soil and water conservation, enabling people to consciously change their production and lifestyle, and having sufficient funds to invest in soil and water conservation and reduce soil erosion.

Abstract:
Human needs like food and clean water are directly related to good maintenance of healthy and productive soils. A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources. This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency. It is important to keep in mind that both soil and water are limited resources. Thus, wise use of these natural resources is a fundamental prerequisite for the sustainability of human societies. This Special Issue collects 15 original contributions addressing the state of the art of soil and water conservation research. Contributions cover a wide range of topics, including (1) recovery of soil hydraulic properties; (2) erosion risk; (3) novel modeling, monitoring and experimental approaches for soil hydraulic characterization; (4) improvement of crop yields; (5) water availability; and (6) soil salinity. The collection of manuscripts presented in this Special Issue provides more insights into conservation strategies for effective and sustainable soil and water management.

Abstract:
The designation of World Heritage Sites (WHS) by UNESCO is the principal international and formally recognised strategy allowing the conservation of sites of outstanding cultural value throughout the world. This study demonstrates that soils and sediments influenced by cultural activities retain cultural records (soils and sediments-based cultural records, hereafter abbreviated to SSBCR) associated with WHS, and further the understanding and contribute to the cultural value of WHS. Considering The Heart of Neolithic Orkney WHS and its surrounding landscape as the study location, systematic fieldwork is combined with geoarchaeological analyses including soil organic matter content, pH, particle size distribution, phosphorus concentration, soil magnetism and thin section micromorphology to determine the nature of the SSBCR. Chronologies of the formation of SSBCR and of palaeo-environmental records were ascertained using radiocarbon analyses and optically stimulated luminescence analysis. Findings of particular importance to the interpretation of the WHS are the identification of a Late Neolithic SSBCR located between the WHS monuments. This SSBCR is a valuable cultural record of a specific Late Neolithic community and provides significant insight into the interaction between settlement and ritual aspects of the Orcadian Late Neolithic. An understanding of these interactions is of crucial importance to a fuller interpretation of the WHS and to the wider discussion of the Orcadian Neolithic. The implications of this research to other WHS designated for their cultural value are discussed, together with future conservation considerations for this specific WHS.

Abstract:
The applications of multispectral and morphometric image analysis to soil thin section descriptions is examined. It is shown that unsupervised classification and contrast stretching can be used to enhance and label features of interest. Morphometric measurements, allow the shape and abundance of features in thin sections to be compared and statistical relationships established. This method of analysis offers a precision beyond that which is possible using a qualitative approach. Using soil micromorphology as the main analytical technique a case study was carried out to evaluate the applicability of image analysis to an investigation of an archaeological site at Lairg in northern Scotland. The interactions of anthropogenic activity and pedogenesis since the Bronze Age is examined. The condition of the soils prior to the Bronze Age is not known because no buried soils predated this period. Evidence suggests that in freely draining situations complete podzols might have formed by this time. During the Bronze and Iron Age intensive cultivation of soils occurred with associated erosion. In areas of the site, where human activity is dated to the Post Medieval period, deepening of A horizons is apparent and the soils are maintained as Brown Podzols. In many areas where human activity stops stagnopodzols are the dominant soil type. The potential of image analysis to aid soil micromorphological descriptions is demonstrated. Contrast stretching aided a qualitative subdivision of thin section slides during the case study. Morphometric analysis confirmed a relationship between shape of voids and c/f ratios in an Iron Age buried A horizon, A PM buried A horizon and an undated deep topsoil. It is concluded that the full benefits of image analysis, when used as a routine tool to aid thin section descriptions, will only be realised when procedures become more interactive and processes can be speeded up.

Abstract:
Recent declines in returns from primary forest products in New Zealand and projected increases in world food prices have led to the land-use conversion from plantation forest to pastoral farming in many lowland areas. After decades of forest cover the soils are in many cases less than adequate for pastoral farming, as they are acidic, with toxic levels of exchangeable aluminum, and contain low levels of available nitrogen (N), very high carbon (C):N ratio, and are devoid of earthworms and structural integrity. Overcoming the major site limitations of low soil pH and available N was a major priority and a field experiment was established in April 2005 to determine the impact of various rates of lime and N in relation to pasture establishment and production. Concerns about the short and long-term effects of these inputs on biological soil quality gave rise to the present study. The effects of land-use change and establishment inputs were assessed by comparison of selected treatment plots with two adjacent reference sites (long-term pasture and a 60–year Pinus radiata forest) on the same soil type. The effects of lime and N on soil biological quality were investigated under field and controlled environment conditions by determination of: microbial community structure (phospholipid fatty acids - PLFA), microbial biomass (total PLFA), and microbial activity (dehydrogenase activity). Soil physical (percentage water-stable aggregates) and chemical (pH, and total C and N) properties were also determined. Similarly, the effects of earthworm addition on soil biological properties were explored in a short-term glasshouse pot experiment. The role of earthworms as indicators of soil biological quality in the field was assumed by nematodes and these were assessed in field trial plots and the reference sites mentioned above. Land-use change and applications of lime and N contributed to changing the microbial community structure determined by principal component analysis of transformed PLFA data. However, the effect of lime was more pronounced in the field, while N contributed most to changing microbial community structure in the glasshouse. Mean microbial activity in the field increased from 4 µg dwt/hr without lime to 16 and 21 µg dwt/hr where lime was applied at 5 and 10 tons/hectare (t/ha), respectively. Mean microbial activity in the field was markedly higher (7-fold) than in the glasshouse at similar rates of lime. Lime application also increased soil moisture retention in the field, mean gravimetric soil moisture increased from 0.33 in control plots to 0.38 and 0.39 in plots treated with 5 and 10 t/ha lime, respectively. Lime application was associated with greater soil aggregate stability. Soils from test plots treated with 5 and 10 tons/ha lime had 45-50% water-stable aggregates compared to 34% in treatments without lime. After 16 weeks in pots, earthworm treatments increased mean plant dry matter (DM)/pot by at least 19% above the control. The increase was attributed primarily to greater N mineralization in the presence of earthworms. For the duration of the trial the earthworm species tested (Apporectodea caliginosa and Lumbricus rubellus, individually or combined) did not affect any of the measured soil microbial properties. However, the survival rate of A. caliginosa was 83% compared to 25% for L. rubellus. The control not receiving any lime or N and plots treated with 10t/ha lime and 200 kgN/ha had similar nematodes species composition, comprising 40% each of bacterial and fungal feeding nematodes. They differed markedly from the reference sites as the forest soil was dominated by plant associated species (38%) and the long-term pasture had 44% plant parasitic nematodes. Accordingly, the soil food web condition inferred from nematode faunal analysis characterized all test plots as basal, stressed and depleted, while the forest soil was categorized as highly structured and fungal dominated. The findings of this thesis demonstrated that land-use change from forest to pasture can have significant impacts on soil biological properties, earthworms can contribute to pasture productivity even in the short term, and nematode faunal analysis is a robust and reliable indicator of soil biological quality.

Abstract:
This study reports forest structure, regeneration and the soil properties from unlogged and logged forest in the Bulungan Research Forest, Malinau District, East Kalimantan, Indonesia. Four sites were compared by using four 1-ha replicate plots in each of primary forest (PF), 5, 10 and 30-yr old logged forest (LF-5, LF-10, LF- 30). The tree species composition differ among forest types, as it was shown that the mean value of similarity indices for all pairs were 0.215 (for the Jaccard index) and 0.353 (for the Sorensen index). The low values for similarities among forest types were most probably caused by low numbers of species shared between each forest type. Both correlation values, r = 0.023 for Jaccard index and r = 0.031 for Sorensen index, showed no strong correlation between the similarity index (C) and the distance between forest types. This supports the use of a chronosequence approach. A total of 914 tree species with ³ 10 cm dbh were recorded from 223 genera and 65 families. There were no significant differences in mean species numbers (166 – 180/ha) among treatments. Mean density of species was lower in LF-5 and LF-10 (501/ha) than in PF or LF-30 (605/ha and 577/ha); similarly to mean basal area (LF-5, 28.5 m2/ha; LF-10, 32.6 m2/ha) vs. PF (45.8 m2/ha) and LF-30 (46.9 m2/ha). Dead wood on the forest floor was significantly higher in LF-10 (75 m3/ha) than in the other treatments. Seedlings (< 2 cm dbh) of 1,022 species were recorded from 408 genera and 111 families. The mean number of tree seedling species ranged between 170-206; the mean density of seedlings was about two-fold lower in LF-10 (2790/ha) than in the other treatments. Saplings (>2 – 9.9 cm dbh) of 802 species belonged to 241 genera and 65 families. There was a high variability in species richness across treatments (89 – 191/ha), but not in stem numbers. The Dipterocarpaceae family was dominant in all treatments, followed by the Euphorbiaceae. The soils were acidic, low in nutrients and had low to very low fertility. Both primary and logged forest areas are marginal or not suitable for sustained production of plantation crops. Logging caused soil compaction in LF-30. Although in terms of number of species and trees, amount of BA, number of saplings and seedlings LF-30 appeared to have satisfied prescriptions for a second harvest, ecologically the forest is far from mature. The Indonesian Selective Cutting and Replanting (TPTI) system may need to be revised to a 35 – 45 year cycle to ensure long-term forest productivity in terms of not only timber but other goods and ecosystem services, the value of which are never quantified in monetary terms, but can be higher than the timber revenue.

Abstract:
Organic mulches and cover crops mulched in situ were assessed for their effects on B. cinerea primary inoculum and disease levels in inflorescences at flowering and/or bunches at harvest. Organic mulches were used to enhance biological degradation of vine debris to reduce levels of B. cinerea primary inoculum the following season. Four mulch types (anaerobically and aerobically fermented marc (grape pressings), inter-row grass clippings and shredded office paper) were applied under ten-year-old Riesling vines in a ten-replicate randomized block design in New Zealand over two consecutive years. Plastic mesh bags, each containing naturally infected vine debris, were placed under vines on bare ground (control) and at the soil-mulch interface, in winter (July) 2003 and 2004. In each year, half the bags were recovered at flowering (December) and the remainder at leaf plucking (February), for assessment of B. cinerea sporulation from the vine debris and debris degradation rate. Bait lamina probes, which measure soil biological activity, were placed in the soil-mulch interface three weeks before each of the two bag-recovery dates in both years and were then removed and assessed at the same times as were the bags. All mulches led to a reduction in B. cinerea sporulation. This reduction was significantly correlated with elevated rates of vine debris decomposition and increased soil biological activity. Over both years, compared with the controls, all treatments gave a 3-20-fold reduction in B. cinerea sporulation, a 1.6-2.6-fold increase in vine debris degradation and in the two marc and the paper treatments, a 1.8-4-fold increase in activity of soil organisms. The mulches also altered vine characteristics and elevated their resistance to B. cinerea through changes to the soil environment. Functional soil biological activity, as measured by Biolog Ecoplates and bait lamina probes, was increased 2-4 times in the two marc and paper treatments, compared with the control, an effect relating to the elevated soil moisture and reduced temperature fluctuations under these mulches. Soil nutrient levels and the C:N ratios were also affected in these treatments. The mulched paper lowered vine canopy density by up to 1.4 times that of the other treatments, an effect which probably led to elevated light penetration into the canopy and consequent increased canopy temperature, photosynthesis and lowered canopy humidity. These changes to soil and vine characteristics increased grape skin strength by up to 10% in the paper treatment and sugar concentrations by 1.2-1.4 °Brix in the two marc and paper treatments. The severity of B. cinerea infections in the anaerobic marc, aerobic marc and paper treatments were reduced to 12%, 3% and 2.2% of the control, respectively, in field assessments averaged over two consecutive harvests. Cover crops mulched in situ had similar effects to those of the organic mulches, increasing soil biological activity and reducing B. cinerea primary inoculum and the severity of B. cinerea infection in grapes at harvest (2006). Inter-row phacelia and ryegrass were mulched in winter 2005 and compared with a bare ground control, under 10-year-old Chardonnay vines in a ten-replicate randomized block design. Functional soil biological activity increased by 1.5-4.5 times in the two cover crop treatments compared with the control, an effect possibly related to elevated soil moisture in these treatments. This increase in soil moisture and soil biological activity increased vine debris degradation, reduced B. cinerea primary inoculum on the debris and decreased B. cinerea severity at flowering (December 2005) and harvest (April 2006). These results show the potential of organic mulches and cover crops mulched in situ to enhance soil ecosystem services and improve the sustainability of viticultural practices.

The Soil and Water Conservation Law was legislated and announced on July 25, 1994. This is the final accomplishment for 20years from industry, government and academic teams. The formulating of this law can be regarded as the most important source of soil and water conservation for hillside project. The objectives of the legislation is to protect Taiwan's water conservation, water and land resources, and relief water and soil disaster. It is an important law to assure the safe living environment and enjoy life for Taiwan citizens. With the popularization of the smart phone and wireless network, the APP software was used world-wide. Variety of application software makes much convenit than old generation in human life. The smart phone does change user's habits. In the past, user needed to use the computer connected to the internet to obtain information such as weather forecasts, and traffic route planning. After the available of smart phones, it can be used to fetch life information and make a convinient life. ER Model, SQL Server, Super Pad and Smart Phone are used in this study to develop "Mobile Water and Soil Conservation Information System for Hill side". The system integrates Hillside data, Land Usage, Ownership division, Land Ownership, and Engineering Inspection Operations. Soil and water conservation staffs can use smart-phones in the outdoor survey through wireless network to update geology, soil, major road systems, land usage, engineering distribution, location, and hillside related data at the first time. This can significantly reduce human error, improve the timeliness and accuracy of the information, provide a powerful management tool for soil and water conservation projects.

To improve the understanding of knowledge of soil and water conservation, the Soil and Water Conservation Bureau established the first outdoor classroom as a site for promotion and propaganda in 1989. The volunteers were recruited to help the educational propaganda in 1991. The training programs were then held to make the transformation of volunteers because of the Volunteer Service Act promulgated in 2001. Therefore, the study selected the soil and water conservation volunteers as the research object. The objective of this study was to understand the difficulties and needs of soil and water conservation volunteers during the services. The participation motivation, organizational commitment and job satisfaction was investigated by the questionnaire survey. The results were expected to be used as a basis for volunteer training and management. The data of questionnaire were analyzed by IBM SPSS Statistics 21. The results showed that the backgrounds of soil and water conservation volunteers were in high homogeneity. There were not many difficulties encountered during the services. However, the demands in professional training programs were high. The main participated motivations were serving others and self-achievement. The organizational commitment and job satisfaction were shown to be satisfied. However, the volunteers with low monthly income and high seniority showed significant differences in the participated motivation, organizational commitment and job satisfaction. The Pearson product-moment correlation was used to estimate the correlation. The correlation coefficient between the participated motivation and organizational commitment was 0.749. The correlation coefficient between the participation motivation and job satisfaction was 0.734. The correlation coefficient between the organizational commitment and job satisfaction was 0.776. The participated motivation, organizational commitment and job satisfaction were high-positive correlated.

Abstract:
Abstract Conservation agriculture (CA) has been highly promoted due to its potential to ensure high crop yields even in the face of changes in climatic factors. However, the actual benefits associated with CA are not only focused on food security but are also site specific. This study sought to understand the benefits of CA in improving livelihoods in a changing climate in Hanjahanja and Sawali sections of Bazale Extension Planning Area in Balaka District. Specifically, it analysed CA's contribution to farmers' livelihoods and also the challenges and opportunities of CA in climate change adaptation. Data was collected through household surveys (n = 153), key informant interviews (n = 9), focus group discussions and field observations. The study found that due to CA adoption, the majority of the farmers in both Hanjahanja and Sawali sections had realized positive livelihood outcomes, mainly through improved food security and increased incomes. Despite the similarity, Hanjahanja farmers reported decrease in yields in seasons marred by floods. However, farmers faced several challenges due to CA adoption, which included high labour demands, rainfall variability and lack of inputs. Even so, improvement in soil moisture, soil erosion control, improved food security, presence of several institutions and enabling environment offered more opportunities of CA in adapting to climate change. CA, therefore, improves the livelihoods of the farmers except in times of floods. Hence, deliberate policies by the government to promote adoption of CA are required to take advantage of the benefits of CA. Research should also be done on how best to reduce the negative effects of CA on farmers' livelihoods.

Abstract:
AbstractGlobal warming has emerged as a major challenge to development and human wellbeing in Sub-Saharan Africa in general and Nigeria in particular. Periodic incidents show that this challenge will continue and increase in impact on all aspects of natural resources – agriculture, ecosystems services, biodiversity depletion, environmental degradation and human health. Recognizing the enormous potential of underutilized plant genetic resources (PGRs) is crucial as sources of solutions to a number of these threatening challenges emanating from climate change (food and nutrition insecurity, genetic erosion, loss of agro-biodiversity, green job growth and income generation) cannot be over-emphasized. Sphenostylis stenocarpa (Hochst. ex. A. Rich) Harms., commonly known as African yam bean (AYB) belonging to the leguminous Fabaceae, is an underutilized PGR with rich portfolio which could serve as vital source of robust adaption and resilient germplasm for vulnerable local communities in Nigeria. Its substantial nutritional, environmental, cultural, social, medicinal, industrial and soil restorative potentials underpins its position as climate – smart species. Enhancing the potentials of African yam bean via robust innovative approaches for wider utilization through accelerated research, farmer seed exchanges, in-situ and ex-situ conservations, farmers selection, and policy programs such as seed sovereignty will accentuate its adaptation and used as resilient climate –smart species for the vulnerable groups in Nigeria to cushion impact of climate change.

Abstract:
In severely cold climate, significant amount of energy is used to heat buildings. Both the theoretical computation and experiments show that it is difficult and uneconomical to use solar energy collected merely in winter. A new method has been developed to store solar energy during summer, fall, and spring for winter heating. This paper presents in details the combined heating and cooling system by solar ground-source heat pump (GSHP) and short-term phase change material (PCM) thermal storage. The hybrid system and season-shift mode can make the sustainable use of solar energy possible. As for the above system, the solar energy collected is stored into soil through the U-tube heat exchanger. In winter, the thermal energy is taken out for heating using the GSHP. At the end of the heat supply season, the underground soil temperature may drop below 0°C. Then some heat exchangers begin to store the heat into soil while others stop. In summer, the U-tube heat exchanger is used to produce low temperature water without compressor to cool the room. The project was supported by the Energy Conservation Laboratory at Harbin Institute of Technology (HIT). The whole systems, which have run for over two years, consist of a flat plate solar hot water system installed on the roof, a soil thermal storage system, a GSHP system, a PCM thermal storage system and heating-cooling system. The measured results show an average heating coefficient of performance (COP) of 3.2 in winter and the cooling coefficient of performance (COP) of 18.0 in summer. The PCM thermal storage system has been investigated by numerical simulation and experiments in the cold climate. In most time of winter, the PCM thermal storage system was used to supply heat, while solar GSHP was also used during continuous cloudy days and severely cold days. The result shows that above method is feasible. The most advantage of this system is that it does not need the usual energy equipment. The numerical analysis has been used to investigate the thermal energy balance of the underground soil. The variation of the soil temperature field around the U-tube heat exchanger has also been studied, not only for the single exchanger but also for multiple exchangers. The underground soil makes the yearly thermal balance possible because the solar energy supplies the heat that is extracted from the soil for heating in winter. Then this system can operate for a long period.

Abstract:
The aim of the recently published climate control by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) is a reduction of the German greenhouse gas emissions down to 20 % in 2050, compared to the generated greenhouse gas in 1990. To reach the given target a huge growth in renewable energy is necessary. One of the most potential possibilities to produce renewable energy in Germany will be the installation of offshore wind turbines. During the installation of offshore wind foundations such as monopiles, tripods, tripiles and jackets, mostly large tubular steel piles are impact driven to final penetration depth. In the process of impact driving, considerable underwater sound emissions will appear. In recent times, peak sound pressure levels above 190 dB re 1 μPa have been measured at a distance of 750 m away from the installation ground. These peak sound pressure levels, produced during the installation of any kind of driven offshore foundation, is potentially harmful to marine life, in particular to marine mammals such as harbor porpoises, harbor seals or grey seals. To protect the marine life the German Federal Maritime and Hydrographic Agency (BSH) set the maximum allowed underwater sound pressure level to 160 dB (SEL) at a distance of 750 m away from pile driving. To reach the given target by the BSH a new underwater piling noise mitigation system using so called hydro sound dampers (HSD) is presently developed at the Institute for Soil Mechanics and Foundation Engineering at the Technische Universität in Braunschweig (IGB-TUBS). After small scale tests in the so called ‘large wave channel’ in Hannover a full scale test was performed in the Baltic-Sea some weeks ago. The results of the measurements are very promising, as a reduction of 12 up to 20 dB could be generated. Besides existing noise mitigation systems one of the main advantage of the hydro sound dampers is, that the mitigation can be pre-adjusted to a predefined frequency range, as marine mammals are sensitive only for a certain sound frequency range. In this paper, the results of the small and large scale tests and some new research findings concerning the shape and the material of the hydro sound dampers will be presented.
