The impact of climate change towards water surface resources is crucial, particularly in developing and non-developing countries. Groundwater as a main water resource is thus an essential. However, contamination due to hydrocarbon spills affects the groundwater as a water resource, especially as a main source of drinking water. This chapter investigates the light non-aqueous phase liquid (LNAPL) penetrations in double-porosity soil with different moisture contents and with or without vibration impact. It also explains the LNAPL penetration phenomena by employing image analysis. The physical laboratory experiments were implemented using an acrylic cylinder, a mirror, toluene and a Nikon D90 DSLR digital camera. Prepared soil was poured in an acrylic cylinder and compressed with compressor until it became 10 cm in height. LNAPL was then poured instantaneously onto the acrylic cylinder that was filled with soil sample. The LNAPL penetration patterns were recorded and monitored using a Nikon D90 DSLR digital camera. The processing technique was conducted at predetermined time intervals using Surfer software and Matlab routine to plot the LNAPL pattern. The results showed that a higher penetration rate of LNAPL occurred with higher moisture content and without vibration impact. The penetration time for LNAPL to reach the bottom of the soil sample was found to be longer for the soil that had low moisture content and with vibration impact.

Earthworks are the embankments and cuttings that allow a railway to maintain a certain line, level and grade through the landscape. Earth embankments consist of an engineered bank of earth that carries the railway above the natural ground. A cutting is used to carry the railway through ground with a natural level above the line of the railway. Modern (post 1960s) earthworks are carefully engineered to perform well. However, many railways run on earthworks that were constructed over 100 years ago without the use of mechanised plant. The quality of construction of older earthworks was often poor compared with present-day engineering practice. Ageing of the earthwork structures, and the greater demands of heavier and faster trains and climatic change, means that earthworks suffer ultimate and serviceability failures that can present operational difficulties. Older earthworks that fail or do not perform well require maintenance and repair, and sometimes complete replacement. This chapter explores the main engineering considerations for modern earthworks, and the challenges associated with older earthworks including their modes of failure and upgrade and repair.

The major component of agriculture production includes the type of seed, soil, climatic conditions, irrigation pattern, fertilizer, weed control, and technology used. Soil is one of the prime elements in modern times for agriculture. Soil is also one of the primary and important factors for crop production. The available soil nutrient status and external applications of fertilizers decide the growth of crop productivity (Annoymous, 2017). The upcoming research question that needs to be addressed is What is the application of soil data on soil health management for sustaining agriculture? Driven by the need, the aim of the present study is (a) to explore the soil parameters of a district, (b) compare the values with the standards, and (c) pave a way for mapping the crops with suitability of soil health. This study will not only be beneficial for the district to take appropriate steps to improve the soil health but also would help in understanding the causal relationship among soil health parameters, cropping pattern, and crop productivity.

Why did peasants in old-regime Europe scatter their land in small strips within open fields? According to an influential theory advocated by Deirdre McCloskey, the system’s main aim was risk reduction. By spreading out land, peasants were less exposed to the caprices of nature: heavy rains, droughts, frost, or hailstorms. In a time when other insurance institutions were lacking, this approach could be a rational solution, even if, as McCloskey suggests, it could be achieved only at the expense of overall agricultural productivity.

Over the years, McCloskey’s theory has repeatedly been debated. Still, it has never been empirically established to what extent the open fields actually reduced risk. McCloskey offered only indirect evidence, based on hypothetical calculations from short series demesne level yields. Risks on enclosed and open-field land farms were thus never compared.

This chapter presents farm-level harvest variation series, including observations from both types of land. It is based on tithe records of 1,700 farms in Southern Sweden from 1715–1860. Results show that scattering had a limited effect on agricultural risk. The system did protect against small-scale local crop failures. It was less efficient, however, when it came to the large-scale regional harvest disasters that constituted a much more serious threat to peasants of the time. From this perspective, the inner logic of the open-field system is taken up for renewed consideration.

To illuminate the underlying logic of western Kansas farmers’ decisions to irrigate at unsustainable rates and the state’s regulatory policies and practices that enable depletion of the Ogallala aquifer.

Ethnographic interviewing of 39 western Kansas farmers, state water management personnel, and archival research.

Farmers occupy an ambiguous position as petty capitalists who focus attention on their own farms with seasonal planning horizons, and they hold a view of “good stewardship” that melds economic and noneconomic considerations, and that provides a rationale for unsustainable irrigation practices. The state resolves the contradiction between the finite groundwater resource and ideological commitments to economic growth by devolving responsibility for water management to groundwater users.

While the small sample size is likely to be representative of the larger pool of irrigators, further research with other farmers representative of the region will be necessary to verify findings.

Depletion of the Ogallala aquifer contributes to farm consolidation and community decline, and the ecological costs will leave future farmers and remaining communities without the benefits of groundwater. Western Kansas will likely have to revert to a system of dryland farming.

While rapid increase in demand for foods but limited availability of croplands has forced to adopt input-intensive farming practices to increase yield, there are serious long-term ecological implications including degradation of biodiversity. It is increasingly recognised that ensuring agricultural sustainability under the changing climatic conditions requires a change in the production system along with necessary policies and institutional arrangements. In this context, this chapter examines if climate-smart agriculture (CSA) can facilitate adaptation and mitigation practices by improving resource utilisation efficiency in India. Such an attempt has special significance as the existing studies have very limited discussions on three main aspects, viz., resource productivity, adaptation practices and mitigation strategies in a comprehensive manner. Based on insights from the existing studies, this chapter points out that CSA can potentially make significant contribution to enhancing resource productivity, adaptation practices, mitigation strategies and food security, especially among the land-constrained farmers who are highly prone to environmental shocks. In this connection, staggered trench irrigation structure has facilitated rainwater harvesting, local irrigation and livelihood generation in West Bengal. However, it is necessary to revisit the existing approaches to promotion of CSA and dissemination of information on the design of local adaptation strategies. This chapter also proposes a change in the food system from climate-sensitive to CSA through integration of technologies, institutions and policies.

Between 1946 and 1962 the United States detonated 109 nuclear weapons in an area of the Pacific Ocean called the Pacific Proving Grounds, mainly at the Enewetak and Bikini Atolls in the Republic of the Marshall Islands. The British nuclear testing program spanned eleven years (1952-1963) and involved detonation of 21 weapons in addition to a number of smaller-scale experiments (the “minor” trials) in South Australia. In both cases lands that were inhabited by an original people were extensively contaminated by the testing and, following its cessation, these people desired the return of their lands in a condition that would support resumption of traditional lifestyles. Cleanup and reoccupation of the contaminated lands in these two arenas raised similar questions of cultural identity and communication and the importance of cultural as well as technical understanding in establishing conditions for safe resettlement. The approaches taken to resolving these questions in the two situations have been very different—featuring extensive stakeholder involvement in a technocratic decision making process in the Maralinga case and a series of attempted negotiations and claims under the terms of trust agreements with the U.S. government in the Marshall Islands case. Similar questions regarding what constitutes a safe final condition and the means by which safety will be maintained remain in each case however. The Australian case has reached the more definitive outcome of the two. A jointly drafted comprehensive environmental management plan, if fully implemented and sustained over the time periods necessary, could facilitate a semblance of the outstation lifestyle that the aboriginal Maralingan people desire. But what has been agreed to may still prove very difficult to live with given the levels of residual contamination and the many ways that traditional cultural practices put people in intimate contact with the land.

This paper suggests that a corporate-environmental food regime is emerging as part of a larger restructuring of capitalism. Like past food regimes, it reflects specific social and political compromises, which I interpret through the social movement concept of interpretive frames. The diasporic-colonial food regime of 1870–1914 grew up in response to working class movements in Europe, and created a historically unprecedent class of commercial family farmers. When world markets collapsed, those farmers entered into new alliances, including one that led to the mercantile-industrial food regime of 1947–1973. Lineaments of a new food regime based on quality audited supply chains seems to be emerging in the space opened by impasse in international negotiations over food standards. Led by food retailers, agrofood corporations are selectively appropriating demands of environmental, food safety, animal welfare, fair trade, and other social movements that arose in the interstices of the second food regime. If it consolidates, the new food regime promises to shift the historical balance between public and private regulation, and to widen the gap between privileged and poor consumers as it deepens commodification and marginalizes existing peasants. Social movements are already regrouping and consolidation of the regime remains uncertain.
