Analýza vývoje zemědělství / Analysis of the Development of AgricultureJaša, Stanislav January 2011 (has links)
Agriculture has not been a mean of securing a food for nations for a long time. Today, thanks to the European union policy, the business activities of agricultural enterprises head towards to the energetics industry and to other industries like heating, forestry or services that enable the companies to diversify their activities beyond the borders of the primary sector. The reasons for a decision of extending the strategic focus of business are many: smaller dependency on weather, better market position in the relevant micro environs, more effective use of agricultural land, local energetic self-sufficiency. This thesis analyses especially the transition of the Czech agriculture from the concept of securing the food self-sufficiency of the state towards to the concept of securing energetic self-sufficiency of the state, facilitated by the renewable energy sources produces by farmers, and other development trends in the Czech agriculture in the European transnational, Czech national and local business context.

The feasibility of carbon-subsidized afforestation projects : a case study of ChinaHou, Guolong 11 November 2020 (has links)
Afforestation projects in China have substantially contributed to national CO2 sequestration and play an important role in international climate change mitigation. However, these nation-wide afforestation projects are usually funded by the national government, with very large and unsustainable investments. It is important to find alternative sources of funding to finance afforestation, and convince poor farmers to become involved in afforestation projects. Carbon-subsidized afforestation could be the solution. The current study aims to find i) whether farmers need additional subsidies to reforest their marginal farmland; if so, ii) whether the value of carbon sequestration of afforestation can offset farmers' net costs. To do this, first I determine the amount of carbon sequestration though afforestation. Second, I assess the value of carbon sequestration, the costs and benefits of afforestation projects, and the costs and benefits of crop production. Third, I investigate the optimal rotation period of the plantations considering a joint production of timber and carbon, for different species. Results show that total carbon sequestration through tree biomass and soil carbon following afforestation differs among tree species and stand age as well as across regions. Economic trees sequester less carbon than ecological trees and bamboo. Among economic trees, nut trees with an inedible hard shell sequester more carbon than fruit trees. The regional context significantly influences the carbon sequestration potential, with more carbon sequestered in southern and eastern regions than in northern regions. Bamboo also shows a remarkable carbon sequestration potential, which is even greater than Chinese fir and Poplar in northern regions. Although afforestation programs have huge potential to store carbon, the voluntary acceptance by landowners crucially depends on their economic outcome. I found that usually carbon credits can compensate for the opportunity costs of alternative land uses, except i) when highly profitable croplands are afforested, in which case carbon credits are not sufficient, and ii) when croplands that generates low incomes are afforested, in which case carbon credits are not needed. Fruit trees are the most cost-effective option for afforestation. Bamboo afforestation is economically attractive if carbon revenues is included. The minimum price of carbon credit decreases with increasing project duration because more carbon is stored when time increases. This does not hold for fast-growing trees like Eucalyptus, for which the minimum price increases with extended project duration. Given the temporal variations of joint production of timber and carbon sequestration, the carbon accounting regimes (tCER, temporary Certified Emission Reductions and lCER, long-term Certified Emission Reductions) have a significant impact on the optimal rotation as well as on the revenue. Forest managers have an incentive to use tCER accounting to finance slow-growing plantations, and lCER for fast-growing ones. I perform a sensitivity analysis detects the changes of rotation period with different carbon prices and discount rates. While the optimal decision for slow-growing species (e.g. Chinese fir) is highly sensitive to changes in both variables under tCER accounting, the results concerning fast-growing species (e.g. Eucalyptus) are most sensitive under the lCER accounting regime. In contrast, carbon revenues have a minimal impact on the optimal rotation of Poplar plantations, no matter which regime is applied. I conclude that carbon-subsidized afforestation is a feasible way to offset the opportunity costs of retired farmland and support the livelihood of farmers. The findings can contribute to the efficient and sustainable management of forestry projects using carbon sequestration, while the methodology can also be applied to other regions in the world.

Neoliberalizace zemědělství v Africe a její dopady / Neoliberalization of agriculture in Africa and its impactsJirsa, Jan January 2020 (has links)
The presented thesis examines impacts of neoliberal policies on agriculture in the developing countries using the example of Zambia and Angola. It is based on a comparision of two most similar countries, which have been different in their approach to implementation of neoliberal policies. Another objective of this thesis is also the spatial transformation of Zambia's agriculture as a result of implementation of policy conditions in structural adjustment programmes. The focus of the paper is motivated by lack of similar approaches in research of neoliberal agriculture policies. This thesis also analyszes research of neoliberalism of agriculture and food regime theory, which has already been carried out. A large amount of data was compiled and processed from several data sources, and utilised to evaluate research questions. Research has confirmed decline in food crops production and yields in Zambia as a result of neoliberal policies, which could threaten the food sovereignty of the country. Furthermore, changes in the spatial distribution of crop production were observed, which are mainly related to the abolition of subsidies and different farmers behavior due to the introduction of Structural adjustment programs. Key words: Angola, agriculture, agriculture subsidies, neoliberalism, Structural...
