'Penetrating' foreign lands: contestations over African landscape. A case study from Eastern Zimbabwe

While it was happening, European expansion was often legitimised by evoking frontier images: pioneers setting off from the metropolis, penetrating wilderness in order to open access to resources, like minerals, living-space, and fertile lands. Central to the ideology of the frontier is the notion of 'no-man's land'. These 'pioneers', however, often had to face local inhabitants and their interpretations and uses of this land. Thus it will be argued that contestations over landscape were at the same time battles over the legitimation of European expansion, as well as over local perceptions of this process. Ideologically, contestations by Europeans and Africans become apparent in the sexualisation of landscape. This paper is based on the case study of a Valley in eastern Zimbabwe on the border with Mozambique, and more specifically of two tea estates which were established in the rainforest. Unusually late for the region, European influence in this remote area only began to become significant in the 1950s which were an important turning point regarding land and landscape in the area. These years of great change will be analysed in order to map out different strands of interest by the main parties involved. It will be demonstrated that their readings of landscape translated into contestations over land. A recent example of such a conflict will be given.

Attityder till betygsättning i ordning och uppförande : En studie bland lärare och elever i Ålands lyceum

Syftet med den här uppsatsen har varit att ta reda på hur lärare och elever i Ålands lyceum förhåller sig till ordnings- och uppförandekriterier i betygsättningen. Vi har sett på skillnader mellan kön och också mellan olika ämnen och vi har också jämfört vårt resultat med tidigare undersökningar som gjorts i Sverige. Vår undersökning har gjorts bland 104 elever i årskurs två på gymnasiet och åtta lärare i ämnena matematik, historia, svenska och idrott. Undersökningen bland eleverna gjordes genom enkäter och bland lärarna genom intervjuer.Resultatet visar att lärarna tycker att ordning och uppförande ska vägas in i ämnesbetyget, precis som det görs nu i Ålands lyceum. Det har visat sig att en majoritet av eleverna vill ha ett separat betyg eller omdöme i ordning och uppförande. Flickorna är klart positivare till ett separat betyg i ordning och uppförande. De tycker också att ordnings- och uppförandekriterier ska vägas in mera i betygen. Det som vi också kommit fram till är att lärarna följer läroplanen i stor utsträckning, vilket till stor del beror på att de fått göra den själva. Resultaten mellan vår undersökning och tidigare undersökningar gjorda i Sverige skiljer sig inte så mycket, trots att lärarna på Åland ska ta hänsyn till ordning och uppförande i betygsättningen, medan lärarna i Sverige inte ska det.

Evaluation of the Conservation Lands of Maine Based on Presence of Habitat Suitable for Listed Species

“Conservation Lands” include both public and private lands that are devoted to the protection of wildlife and natural resources. “Listed Species” include federally and state endangered and threatened animals that are in danger of extermination in the state of Maine. The purpose of this study is to determine how well conservation lands are protecting the habitats of listed species. GAP data was used for 13 terrestrial vertebrate species indicating the presence or absence of suitable habitats. This data was compiled in GIS, generating a layer showing the number of listed species an area is suitable for. The areas that were suitable for at least one habitat were compared to answer three questions: (1) Is there is a difference between the presence and absence of listed species on protected lands and lands that are not protected? (2) Is there is a difference between the presence and absence of listed species on public lands managed by the state and the federal government and private land? (3) Is there is a difference between the presence and absence of listed species on lands protected under easements and lands that are protected fee simple? We found significant differences between all three categories. Conservation lands, private lands, and lands held under easement protect the habitat of listed species most effectively. We believe that this is due to the large number of private land trusts in the state of Maine and the effective management strategies of state lands.

Viewshed Analysis of the Lands of Belgrade Regional Conservation Alliance

The Belgrade Regional Conservation Alliance (BRCA) has acquired a great deal of land in the Belgrade Lakes region of Maine and is currently in negotiations on many pieces of land throughout the area. Data available online from the Maine Office of GIS, and data from the BRCA were used to carry out this analysis. One area of interest is Mount Phillip, the summit of which the BRCA recently acquired. There is a good view to the south of the mountain, but the potential view to the east and north is in question. This study analyzed the view from the top of the mountain, focusing on two landmarks: Mosher Hill to the east, and North Pond to the north. The analysis shows that both Mosher Hill and North Pond can be seen well from Mount Phillip. These results could help the BRCA both by adding weight to their negotiations to protect Mosher Hill, as well as influencing their decision whether or not to thin part of the forest on Mount Phillip to open up the view of North Pond that is currently blocked.

Economic valuation of collecting water to billing in the aspersion irrigated bean in the no tillage system and conventional crop

The law's project n.676/2000 approved the collecting of billing water for farmers in a maximum foreseen value of US$ 0.01 m(-3) of extracted water in the São Paulo State. As the irrigated agriculture is the activity that consumes more water, the farmers profitability can be affected. This work was to analyze the economic impact of billing water in the aspersion irrigated bean crop to consider the system of conventional production and no tillage system in the Paranapanema municipal district, São Paulo State, Brazil. The indicators used to analyze the economic results were unit variable cost, market price and unit profitability. The results showed that for the aspersion irrigated bean crop in conventional system, the participation of cost to the recourse water in cost variable totality was of 2.5% and in no tillage system the participation was of 2.2%. The fall of profitability just the billing water in conventional crop system and in no tillage system was US$ 0.01 kg(-1).

Yield of upland rice cultivars in rainfed and sprinkler-irrigated systems in the Cerrado region of Brazil

In upland rice, the reduced grain yield that originates from the moisture stress period is related to the plant's tolerance of water deficiency and may vary between cultivars. The purpose of the work presented here was to evaluate the performance of upland rice cultivars in both rainfed and sprinkler-irrigated systems. A split-plot scheme with 8 replicates in a randomised block design was used. The plots were composed of 2 cropping systems (rainfed and sprinkler-irrigated) and the split-plot consisted of 2 cultivars (IAC 201 and Carajas) which are suggested for cultivation in upland ecosystems. Carajas had a greater number of panicles per square metre, higher spikelet fertility and grain mass, and, consequently, a higher grain yield than IAC 201 regardless of cropping system. IAC 201 was more sensitive to water deficiency than Carajas. Sprinkler irrigation improved spikelet fertility, grain mass and upland rice grain yield. Even when cultivars with a higher tolerance of water deficiency are used, a sprinkler-irrigated system may be a viable method to increase upland rice yield throughout most of the Brazilian Cerrado.

An evaluation of direct seeding for reforestation of degraded lands in central São Paulo state, Brazil

As part of a larger study evaluating several silvicultural techniques for restoring tropical moist forests on abandoned agricultural lands in southeastern Brazil, direct seeding with five early-successional Atlantic forest species was tested at three degraded sites, characterized by different soil types and land-use histories, within the Environmental Protection Area at Botucatu, SP. The species used in this study were Chorisia speciosa, Croton floribundus, Enterolobium contorstisiliquum, Mimosa scabrella, and Schizolobium parahyba. Scarified seeds of each of these species were sown in prepared seed spots in replicated, 0.25 ha mixed-species plots at an initial espacement of 1 m x 1 m at each site. of the five species planted, only two, Enterolobium and Schizolobium, showed good seed germination, seedling survival, and early growth rates, averaging 4.1-4.6 cm stem diameter and 1.5-1.7 m height growth during the first 2 years after sowing. These two species constituted 88-100% of the total stand density, which ranged from 1050 to 1790 stems ha(-1) at 2 years. Despite the poor performance of the other species tested, we observed that the natural regeneration of native forest species originating from remnant forests in the general vicinity of our study sites was significantly greater within the direct-seeded plots than in unplanted control plots that were protected from fire and other disturbances.

Response of irrigated wheat cultivars to different nitrogen rates and sources

Altas produtividades de trigo requerem um bom manejo da adubação nitrogenada. O objetivo deste trabalho foi avaliar os efeitos de diferentes doses de nitrogênio na semeadura usando o Entec (fonte de N com inibidor de nitrificação), ou em cobertura, utilizando a ureia, em quatro cultivares de trigo. O experimento foi desenvolvido em área experimental pertencente à Faculdade de Engenharia de Ilha Solteira - UNESP, em um Latossolo Vermelho distrófico epieutrófico álico textura argilosa, o qual foi nativamente ocupado por vegetação de Cerrado. O delineamento estatístico foi o de blocos ao acaso, com quatro doses de N (0, 60, 120 e 180 kg ha-1) na semeadura, usando o Entec, ou em cobertura aos 40 dias (início do alongamento), empregando a ureia e os cultivares E 21, E 22, E 42 e IAC 370, em quatro repetições. Os cultivares de trigo mais produtivos foram o E 21 e o E 42. O cultivar E 22 apresentou maior altura de plantas e altas notas de acamamento, com consequente menor produtividade de grãos. Não houve diferença significativa entre o Entec (aplicado na semeadura) e a ureia (aplicada em cobertura) para produtividade de grãos e para nenhuma das outras avaliações, porém a ureia proporcionou maior teor de N foliar, e o Entec, maior número de espiguetas não desenvolvidas. O incremento das doses de N influenciou negativamente a massa hectolítrica, alterando assim a qualidade dos grãos de trigo. O N aumentou a produtividade de grãos de trigo até a dose de 82 kg ha-1 de N, usando Entec aplicado na semeadura ou ureia aplicada em cobertura.
