Land Policy and Farm Structure: Challenges and Opportunities for Agriculture in the Western Balkan

Although Western Balkan countries are quite different, they can all be characterised by their one shared goal, to achieve the quickest possible accession to the European Union. Even though agriculture plays an important key role within all Western Balkan states, it’s share is the highest in Albania and only Serbia has a trade surplus. Land is a key production factor but all the analysed countries can be characterized by fragmented land structure and low average farm sizes. Mostly based on land ownership issues, a land reform index can be calculated. The major contribution of this paper to the literature is the reevaluated land reform index for the Western Balkans.

Dynamics of Land Use in Recently Settled Forest Areas: a Case Study of Attappady , Kerala

The present study on the dynamics of land use in recently settled forest areas. In the course of events, tribals lost their land; the demographic structure of Attappady changed; the cropping pattern got diversified; traditional techniques of production were ruined; new crops and new techniques of cultivation came to stay; and the entire cost and return structure of production underwent radical change. Migration to Attappady is essentially a continuation of the Malabar migration process from Travancore, through, some people from Tamil Nadu also had migrated to this region earlier. The demographic structure, along with land structure, has changed in favour of the settlers within a short span of time. Lack of security of ownership has acted as a strong reason for wanton exploitation of land resources. The major influencing factors on crop choices among settlers were labour endowment, date of settlement and education. Attappady is an unique ecosystem in Kerala characterized by many interdependables. The latest hand of environmental degradation is a grave danger especially on sloppy terrains,which are under cultivation of tapioca and dry annual crops like groundnuts, cotton, grams etc. Soil erosion as a result of the unplanned cultivation of these crops has resulted in dramatic decline in soil fertility and hence low crop productivity. This calls for a watershed management approach for the sustainable development of the region. A progressive agrarian transformation is warranted to maintain the homegarden as a sustainable production system in ecological and socio-economic terms.

Questão fundiária e sucessão da terra na fronteira Oeste da Amazônia

Foram criados na segunda metade do século XX, no Brasil, diversos órgãos fundiários estaduais que buscavam solucionar os crescentes conflitos de terra. Um dos principais objetivos dos órgãos fundiários era garantir o acesso à propriedade rural, ou seja, possibilitar que o maior número de pessoas pudesse ter um pedaço de terra para trabalhar. Outro papel era o de gestão do patrimônio público. Contudo, na prática verificou-se que a gestão se resumia mais em incorporar as terras devolutas ao seu patrimônio e depois transferi-lo para os entes privados, do que em pensar em uma política na qual seria defi nida, pelos institutos de terra, também a forma de uso e manejo dos recursos naturais. Procuramos mostrar essa questão relacionada à produção de diversas formas de confl itos fundiários relacionados à atuação dos órgãos fundiários. Mas também a compreensão destes em uma nova conjuntura política e jurídica, pois é preciso definir, dentro da estrutura organizacional governamental, qual é o órgão ou a instância responsável pela execução da política agrária, pela gestão dos recursos naturais renováveis e, principalmente, pelas terras devolutas. A análise sobre a situação fundiária e dos conflitos na área da Br-163 (Rodovia Cuiabá-Santarém), é elucidativa de como a visualização da estrutura fundiária é importante para a elaboração de um plano estratégico de ordenamento social, econômico e ecológico.

Notas sobre o caldo de cultura que permeia os atuais embates no campo indigenista

Unlike neighboring countries whose constitutions define their multicultural and multiethnic statutes, the indigenous rights inscribed on Brazilian Constitution are primarily defined by the recognition of territorial occupation. At this moment when the political struggles brings into question the validity of these rights, the text aims to discuss the extent of its application since enactment of the Brazilian Constitution

Photosynthetic pigments in soils from northern Victoria Land (continental Antarctica) as proxies for soil algal community structure and function

Although soil algae are among the main primary producers in most terrestrial ecosystems of continental Antarctica, there are very few quantitative studies on their relative proportion in the main algal groups and on how their distribution is affected by biotic and abiotic factors. Such knowledge is essential for understanding the functioning of Antarctic terrestrial ecosystems. We therefore analyzed biological soil crusts from northern Victoria Land to determine their pH, electrical conductivity (EC) water content (W), total and organic C (TC and TOC) and total N (TN) contents, and the presence and abundance of photosynthetic pigments. In particular, the latter were tested as proxies for biomass and coarse-resolution community structure. Soil samples were collected from five sites with known soil algal communities and the distribution of pigments was shown to reflect differences in the relative proportions of Chlorophyta, Cyanophyta and Bacillariophyta in these sites. Multivariate and univariate models strongly indicated that almost all soil variables (EC, W, TOC and TN) were important environmental correlates of pigment distribution. However, a significant amount of variation is independent of these soil variables and may be ascribed to local variability such as changes in microclimate at varying spatial and temporal scales. There are at least five possible sources of local variation: pigment preservation, temporal variations in water availability, temporal and spatial interactions among environmental and biological components, the local-scale patchiness of organism distribution, and biotic interactions.

Arthropod diversity and community structure in relation to land use in the mekong delta, vietnam

Declining biodiversity in agro-ecosystems, caused by intensification of production or expansion of monocultures, is associated with the emergence of agricultural pests. Understanding how land-use and management control crop-associated biodiversity is, therefore, one of the key steps towards the prediction and maintenance of natural pest-control. Here we report on relationships between land-use variables and arthropod community attributes (for example, species diversity, abundance and guild structure) across a diversification gradient in a rice-dominated landscape in the Mekong delta, Vietnam. We show that rice habitats contained the most diverse arthropod communities, compared with other uncultivated and cultivated land-use types. In addition, arthropod species density and Simpson's diversity in flower, vegetable and fruit habitats was positively related to rice cover in the local landscape. However, across the landscape as a whole, reduction in heterogeneity and the amount of uncultivated cover was associated, generally, with a loss of diversity. Furthermore, arthropod species density in tillering and flowering stages of rice was positively related to crop and vegetation richness, respectively, in the local landscape. Differential effects on feeding guilds were also observed in rice-associated communities with the proportional abundance of predators increasing and the proportional abundance of detritivores decreasing with increased landscape rice cover. Thus, we identify a range of rather complex, sometimes contradictory patterns concerning the impact of rice cover and landscape heterogeneity on arthropod community attributes. Importantly, we conclude that that land-use change associated with expansion of monoculture rice need not automatically impact diversity and functioning of the arthropod community.
