Show moreIndian agriculture is widely believed to be in crisis. There is broad consensus among scholar, policymakers and activists that economic hardships and the changing climate have made sustaining a livelihood through farming increasingly untenable. There is a strong sense that something has to be done to help farmers deal with the crisis, and in recent years agricultural insurance has been presented as a possible fix for rural distress. This dissertation studies how a new agricultural insurance scheme called PMFBY becomes part of everyday social interactions and experiences. Insurance companies often assert that quantified procedures can accurately - and fairly - calculate the extent of agricultural risk, attach a price tag to it and protect against it. Can quantification really be the antidote to crisis? To answer this question I explore how insurance numbers translate to the everyday experiences of rural people in central Maharashtra. I find that, when seen from the perspective of those encountering them in their daily lives, the numbers are anything but straightforward. The effects of quantification were often arbitrary, and despite promises of transparency, they had a tendency to obscure rather than clarify. In short, the numbers turned out to be inconsistent and ambiguous. The dissertation describes how people attempt to make sense of this ambiguity through their moral understandings. It focusses on the (often heated) discussions, the collective pondering such discussions led to, the personal dilemmas it posed as well as the dreams and aspirations numbers became entwined with. I explore how such quandaries unfold and argue that a focus on the morality of quantification brings to light the social life of numbers beyond their 'objective' factuality. Show less

Show moreThis thesis attempts firstly to reconstruct the urban system or systems of the Roman Near east in the second and early third centuries C.E., consisting of the provinces of Syria Coele, Syria Phoenice, Syria Palaestina, Osrhoene, Mesopotamia and Arabia. Secondly it analyses the different regional patterns within these systems. The first two chapters of the thesis describe the urban systems in the north and south of the Roman Near East respectively. The third chapter analyses to what degree the distribution of cities, and their sizes, relate to the agricultural productivity of the urban territories. The fourth chapter takes a detailed look at the largest city of the region, Antioch. The research shows that geographic factors and historical developments certainly played a role in the long term and defined the shape of urban networks in the region, but with ample room for human agency. Although we clearly see population growth compared to earlier periods, Roman cities in the Near East were nonetheless not particularly big, and most could be sustained with agricultural production from their direct hinterlands. From that perspective there is no reason to assume that integration into the Roman empire also brought stronger economic integration. Show less

Show moreFood security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence, exacerbating their impacts. This also leads to increases in events where both stresses co-occur. This co-occurrence results in substantially more yield losses than individual stressors. While detrimental effects of combined drought and salinity stress on crops have been highlighted in small-scale experiments (with only a limited number of crop varieties), large regional uncertainties remain for real-life agricultural settings. Satellite observations offer a promising perspective for enhancing global food security by providing reliable information on arable land extent and food production. Remote sensing has already been used to monitor crop productivity at multiple spatial and temporal scales, though not for yet characterizing crop growth under co-occurring drought and salinity stress. This thesis aims to assess the impact of drought and salinity on agriculture and sustainable development goals using remote sensing technology. Show less

Show moreCotton — supplying approximately a quarter of global textile fibres — has various environmental impacts, including water use, toxicity, eutrophication and greenhouse gas emissions. In this Review, we identify these impacts across multiple life cycle stages. Environmental impacts at the cultivation stage depend on levels of irrigation, pesticide and fertilizer applications. At the textile manufacturing stage, impacts depend on energy infrastructure and manufacturing technologies. At the use phase, impacts depend on consumer habits related to buying, washing, drying and ironing. Depending on the impact category and country, cotton cultivation, manufacturing or use can dominate such impacts. For example, the use phase dominates greenhouse gas emissions in countries with carbon-intensive energy grids. Use of alternative fibres has the potential to reduce these environmental impacts, particularly jute and flax, which have much lower water demands. Opportunities for farmers, manufacturers and consumers to improve the environmental sustainability of cotton textiles include, among others, improving water-use efficiency in agriculture, innovative recycling and laundering less frequently. Future cotton sustainability assessments are needed to fill data gaps related to developing and emerging countries, the number of uses of a cotton garment and further environmental impacts such as salinization, as well as socio-economic impacts.The supplementary information is available here: https://static-content.springer.com/esm/art%3A10.1038%2Fs43017-023-00476-z/MediaObjects/43017_2023_476_MOESM1_ESM.pdf Show less

Show moreThe past decades have shown an increase in recourse to international legal bodies to address disputes over land distribution, uses and rehabilitation. This raises the question as to whether and to what extent international law offers a coherent framework for addressing land as part of environmental peacebuilding. Since land issues have played a role in most armed conflicts that occurred over the past decades, addressing such issues in peace processes is essential for the resolution of these conflicts and for maintaining the peace that has been so hard won. This chapter therefore first examines how international law impacts on decisions with respect to land uses, distribution and rehabilitation in peace processes. This chapter then explores whether and how the notion of environmental peacebuilding can be instrumental in mainstreaming international legal responses for the purpose of achieving a sustainable peace.

Through a case study – including interviews with fourteen experts in the field – the following justice institutions have been identified as relevant: the national human rights institution, the labour offices of the Ministry ofLabour and Social Protection and courts. While keeping in mind that capacity constraints are a product of Kenya’s position within the broader international political economy, this article studies related barriers to justice on the ground. It explains thatthe perceived interests of political and economic elites usurp sound remediation. Show less

Show moreExcess atmospheric ammonia (NH3) leads to deleterious effects on biodiversity, ecosystems, air quality and health, and it is therefore essential to monitor its budget and temporal evolution. Hyperspectral infrared satellite sounders provide daily NH3 observations at global scale for over a decade. Here we use the version 3 of the Infrared Atmospheric Sounding Interferometer (IASI) NH3 dataset to derive global, regional and national trends from 2008 to 2018. We find a worldwide increase of 12.8 ± 1.3 % over this 11-year period, driven by large increases in east Asia (5.80 ± 0.61 % increase per year), western and central Africa (2.58 ± 0.23 %.yr−1), North America (2.40 ± 0.45 %.yr−1) and western and southern Europe (1.90 ± 0.43 %.yr−1). These are also seen in the Indo-Gangetic Plain, while the southwestern part of India exhibits decreasing trends. Reported national trends are analyzed in the light of changing anthropogenic and pyrogenic NH3 emissions, meteorological conditions and the impact of sulfur and nitrogen oxides emissions, which alter the atmospheric lifetime of NH3. We end with a short case study dedicated to the Netherlands and the "Dutch Nitrogen crisis" of 2019. Show less

Show moreAs a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT). Accordingly, an approach based on treatments of seeds (Solanum lycopersicum) and cuttings (Chrysanthemum morifolium) was undertaken to protect plants from their early critical young stage onwards. Known putative defense secondary metabolites were exogenously applied whereas, external application of plant hormones was explored as a means to trigger innate defense responses. Natural Deep Eutectic Solvents (NADES), as environmentally benign solvents, significantly improved the solubilizing properties of poorly-soluble insecticidal metabolites but did not enhance resistance against WFT. On the contrary, seed treatments with the ubiquitous plant hormone jasmonic acid (JA) appeared to induce cultivar dependent defenses as it only reduced silver damage in tomato cultivar Carousel. Sulfuric acid scarification, prior to JA seed incubation, significantly augmented the embryonic receptivity of a non-responsive cultivar thus, highlighting the importance of seed coat permeability. Moreover, we demonstrate that water dipping of indole-3-butyric acid (IBA)-coated chrysanthemum cuttings repeatedly reduced herbivory, both by thrips as well as by leaf miner. Show less

Show moreThis research investigates the changing landscape and land use in two case studies of the coastal villages of St. Kitts and the Kalinago Territory of Dominica. By integrating human and ecological aspects of agrarian landscapes, this research analyzes how land degradation or land change impacts cultural ecosystem services, that ultimately disrupts community wellbeing. First, as a primary goal, the research focus is established together with local communities or stakeholders, identifying both direct and indirect causes of landscape change. Second, by using a variety of qualitative and quantitative methods, but grounded in local participation, the research indicates that landscape change never happens in a vacuum but rather, it is always a part of a larger socio-political context and historical background that must be considered. In both case studies, there remains emphasis on the tangible, as results not only lead to new directions in landscape research but also deliverables used by community stakeholders for continued land sustainability. By investigating the synergies of nature and community within landscape change, this research proposes that local communities assert local agency. This moves away from how local communities fit into global phenomena of land change, to how communities can assert their diversity within a global process. Show less

Show moreThe study looks at the experience of railway development in the countryside between Kano and Zaria. It looks at the ways the inhabitants perceived, appropriated and domesticated the railroad and how their lives were transformed by it. The communities are located in the two Hausa states of Kano and Zaria. Situated strategically on trade routes and the rail line, all the communities with the exception of one were nineteenth century creations. They became significantly important with the construction and operation of the railway in the twentieth century. The railway as the study argued was the most important innovation which transformed the communities from almost nothing to economically significant center's on the rail line. It played a critical role in their social, economic and cultural life much more than previously recognized. The railway is also a double edge sword. It opened many frontiers of opportunities and at the same time indirectly endangered many. It also bread crimes and provided platforms for criminals to operate. The impact of the railway, as the study severally demonstrates differs between the communities. Show less

Show moreDiscussions about colonial chieftaincy in Africa have tended to focus upon the ways in which indirect rule structured and framed traditional authority; for the majority of contemporary historians of British colonialism the question has been to what extent Lord Lugard’s blueprint for effective native administration, The Dual Mandate, invented, shaped, and restructured political and social identity. Whilst acknowledging the importance of these neo-traditional perspectives which focus much on the ways in which colonial frameworks ethnicised and tribalised African society, this thesis argues that indirect rule was as much a spatialising process as it was a tribalising one. Colonial tools of territoriality mapped politics in geographically bounded ways and as a result associating power with place began to assume new importance in the ways African leadership was defined, and given authority. By further exploring the spatial context of traditional power in colonial Malawi through the example of a Tumbuka chief named Timothy Chawinga, this thesis reveals new conclusions about the nature of chieftainship in Northern Malawi. It also provokes new questions about how we understand the role of African traditional authorities more generally, in both the past and the present. Show less

Show moreThe adoption of agriculture is one of the major developments in human history. Archaeological studies have demonstrated that the trajectories of Neolithisation in Northwest Europe were diverse. This book presents a study into the archaeology of the indigenous communities involved in the process of Neolithisation in the Lower Rhine Area (5500-2500 cal BC). It elucidates the role played by these in relation to their environmental context. This work brings together a comprehensive array of excavated archaeological sites in the Lower Rhine Area and indicates that the successive Late Mesolithic, Swifterbant culture, Hazendonk group and Vlaardingen culture societies represent a continuous long-term tradition of inhabitation of the wetlands and their margins. After demonstrating the existence of a diverse Mesolithic background to Neolithisation, the subsequent developments are studied by foregrounding the relationship between local communities and the dynamic wetland landscape. This points to long-term flexible behaviour and pragmatic choices in livelihood, food economy and mobility. For the interpretation of Neolithisation this study emphasises the persistent traditions of the communities involved. New elements are shown to be attuned to existing hunter-gatherer practices. By documenting indications of the mentalité of the wetland inhabitants, it is demonstrated that their mindset remains essentially ‘Mesolithic' for millennia. Show less

By providing an in-depth analysis of his multi-faceted career in the Netherlands and the Malay Archipelago, this study sheds light on the co-evolutionary character of science, governance, and empire. It argues that seeds of Reinwardt’s professional flexibility lay in his practical training in one of Amsterdam’s chemical workshops and his socialization in a broader cultural context where the improvement of society and economy played a crucial role.

Show moreSowing the seed? Human impact and plant subsistence in Dutch wetlands during the Late Mesolithic and Early and Middle Neolithic (5500-3400 cal BC). The understanding of the neolithisation process in the Netherlands has increased considerably during the last decades. A coherent overview of the archaeobotanical research on the transition from hunting and gathering to agriculture was, however, lacking until now. This thesis aims to provide a better understanding of the neolithisation process in the Dutch wetlands by means of the reconstruction of the natural vegetation, human impact, plant use and cultivation practises at the time of the Late Mesolithic, the Swifterbant culture and the Hazendonk group. The study is a literature study based on the analysis of published and unpublished data on pollen, seeds and fruits, wood, charcoal and tubers from four wetland regions. The extensive botanical data sets of recently excavated sites have been combined and compared with evidence of earlier investigations, resulting in a coherent overview and new interpretations. The evidence from the Dutch wetlands has furthermore been compared with that of comparable cultural groups in Northwestern Europe. Show less
