Abstract:

Throughout this thesis I have laid out several factors that have contributed to the sustainability of shrimp farming in Thailand, and if sustainability whilst maintaining production can ever be achieved. To find out the current situation of shrimp farming in Thailand, the history of global and Thai shrimp farming is described. The social and environmental problems of the unsustainable history of shrimp farming in Thailand is then considered. Solutions to these effects conclude that it is up to the consumer to demand for better regulations from the government and the shrimp companies to ensure

Farmland birds in Europe have declined as agriculture has intensified, with granivorous specialists disproportionately affected. Despite grassland based farming being widespread, farmland bird research to date has focussed on mixed and arable farms. Yellowhammers are a red-listed species in the UK. This study investigated year round habitat requirements, diet, and movements of yellowhammers at four grassland dominated farms in Ayrshire, Scotland. Data were obtained via field surveys and trials, radio-tracking and faecal analysis. Fine scale breeding season foraging habitat requirements were st

Abstract:

It has been argued that organic farming sustains a higher biodiversity than conventional farming. This might promote the ecosystem services that exist in agricultural landscapes such as pollination and pest control. Here, I examined the effect of farming system (organic vs. conventional) with respect to the time since farming system transition, landscape heterogeneity and plant richness on pollinating and predatory insects. In total, data from 30 farms were used, of which 20 were organic and 10 were conventional. The data were analyzed using general linear models and model averaging. The resul

Abstract:

To eat or not to eat meat? That has become a central question in the sustainability conversation. There is growing scientific consensus that the global meat consumption issocially and ecologically unsustainable. Planetary and human health concerns aside, there is also a moral dimension to meat, that is, the rights and responsibilities we have towards the animals that make the meat. While there is, indeed, mounting ethical discomfort with meat consumption, scientific and public moral inquiries tend to omit on-farm perspectives. This thesis zooms in on the moral sustainability of cattle farming

Abstract:

This study examines whether aquaculture has the potential to reduce deforestation in the Peruvian Amazon. The natural resources of the Peruvian Amazon are subject to extreme pressures due to increases in subsistence farming, cattle ranching, and logging in the region. The resulting loss of biodiversity has affected the delicate soil balance that is characteristic of the Amazon, and has contributed to water pollution as well as erosion (Guerra et al. 2001). One of the highest rates of deforestation in the Amazon basin can be found at the foothills of the eastern Andes (Lepers et al. 2005), wh

Abstract:

Globally, increasing land-use intensity has led to more intensive farming practices at the local scale and the loss of non-crop habitats at the landscape scale which may affect various ecosystem services. Insect pollination by wild pollinators is especially affected, but their relative impact and possible interactions have been relatively unexplored. There is also considerable evidence for the negative impacts of agricultural activities and agrochemical use on ecosystem services delivered by natural vegetation, but these impacts have not been assessed for the indigenous crop Aspalathus lineari

Abstract:

There is a need of increasing fish production due to the rapidly growing population. The Amazon basin has around 1 million km2 of freshwater area, and a substantial part could be an ideal base for the development of the fish rearing industry. Currently, small-scale fish farming and fishery is commonly observed in the Amazon Basin, but these systems can negatively impact the environment, for example, via eutrophication and overfishing. Here I compare several fish production systems reported for the Amazon Basin to evaluate what is the most sustainable system that should be preferably implemente

In response to this, Shizen Nōhō has emerged in Japan as an alternative way of cultivating food.

Abstract:

An drei Standorten wurde die schädlingsregulierende Wirkung einer Raps-Rübsen-Mischsaat (Verhältnis 9:1) gegenüber einer Raps-Reinsaat bewertet. Des Weiteren wurden naturstoffliche und nach § 6a PflSchG selbst hergestellte Pflanzenschutzmittel als auch eine Käfersammelmaschine zur Regulierung der Stängelrüssler (Ceutorhynchus spp.) und des Rapsglanzkäfers (Meligethes aeneus F.) in Labor- und Freilandversuchen angewandt. In der Mischsaat war die Schaderregerabundanz gegenüber der Reinsaat zumeist erhöht. Diese führte zu einem teils signifikant stärkeren Schaderregerbefall der Rapspflanzen in de

While architects or enlightenment project architects with inventive and feeling for architecture, rarely interfered to their projection. In the practice, the preferred and implemented misconception, that it is a purely purpose-built buildings with economical advantageous solution type, when external design of the building and his effect in landscape plays just a minor role, meant a huge mistake, which disfeature face of a lot of vi

Abstract:

As Áreas de Preservação Permanente (APPs) e a Reserva Legal (RL) foram estabelecidas por lei como alternativas mitigadoras dos impactos da ação antrópica, funcionando como reguladoras do fluxo da água, de sedimentos e nutrientes, formando ecossistemas estabilizados às margens de rios, lagos e nascentes; atuando na diminuição e filtragem do escoamento superficial e do carregamento de sedimentos para o sistema aquático. Nas pequenas propriedades rurais, onde a agricultura de susbsistência ainda é a regra, seus proprietários encontram dificuldades a uma convivência equilibrada entre a exploração
