In Europe, agriculture represents the dominant land use and there is a substantial part of biodiversity associated with those habitats. Therefore, conservation studies should direct to agriculture fields aiming to minimize the biodiversity losses. Vineyards could play a key role in producing win-win solutions for agriculture and biodiversity conservation, as an entrance point of sustainable practices in agriculture management. This study aims to evaluate the influence of different agriculture practices on macroinvertebrate diversity and in the productivity of the vineyards. Comparing these variables, we hope to determine the most sustainable agriculture practices, to suggest conservation measures to enhance sustainability and improve biodiversity in the vineyards. We are comparing Coleoptera, Hymenoptera and Hemiptera diversity and levels of productivity in three differently managed vineyards: conventional, organic and integrated production with controlled doses of chemicals (optidose). Macroinvertebrates will be sampled by pitfalls and colour plates. Study area is Herdade dos Pinheiros of Fundação Eugénio de Almeida, in Évora (Alentejo, Portugal). We expect to find higher macroinvertebrates diversity where there is less disturbance, as in the organic vineyard. And the contrary for the conventional. Also, we are expecting to find little diversity of Hemiptera when there are higher levels of Coleoptera and Hymenoptera diversity, because that means biological control is acting. Finally, we hope to find the best agriculture measures to enhance sustainability and improve biodiversity in vineyards and surrounding areas.

Without a clear understanding of individual farms and farming practice, progression toward more sustainable vegetable production cannot occur. Seventy randomly selected vegetable farmers in Utah were surveyed by telephone and mail to gather baseline data on their agricultural practices. The Utah vegetable farmers profile generated by this survey included a measure of each respondent's attitude toward sustainable agricultural practices and his or her interest in further cooperation with research and extension. A farming index to measure practices used and a perceptual index measuring farmer's views regarding sustainable practices were developed, pilot tested, and refined during the project. Although the perceptual index did not serve as a proxy for actual farm practice, it identified farmers who had an appreciation for sustainable agriculture. Together with the farming index, we now have detailed information on actual farm practices for a variety of different vegetable farmer groups. The use of these two indices will help measure the effectiveness of future research and extension efforts as farmers progress toward more sustainable vegetable production.

Allelopathy is important for agricultural practices as has gained attention in sustainable agriculture management. Therefore, an experiment was conducted to assess the allelopathic effect of siam weed (Chromolaena odorata L. King and Robinson) debris on the germination and seedling growth of rice, mustard and groundnut at four concentrations of weed debris (e.g., 0, 0.25, 0.5 and 1.0 g dry weight per 100 g soil). The weed debris at different concentrations reduced the seed germination, plant height, leaf numbers, leaf area and seedling dry weight of the test crop species. The inhibitory effects of the test crop were positively related to the concentration of siam weed debris in soil. On the basis of average percent inhibition (API), mustard (24.47%) was mostly affected by the siam weed debris followed by groundnut (20.10%) and rice (17.10%). From the results of the study, it is observed that weed debris of siam weed had inhibitory effect on the seed germination and seedling growth of rice, mustard and groundnut. Therefore, the allelopathic activity of the siam weed may play an important role in the management of sustainable agriculture.

Abstract The present paper focuses on spatial management regulations in order to carry out investment in the field of airport facilities. The construction, upgrades, and maintenance of airports falls within the area of responsibility of local authorities. This task poses a great challenge in terms of organisation and finances. On the one hand, an active airport is a municipal landmark and drives local economic, social and cultural development, and on the other, the scale of investment often exceeds the capabilities of local authorities. The immediate environment of the airport determines its final use and prosperity. The objective of the paper is to review legislation that affects airports and the surrounding communities. The process of urban planning in Lodz and surrounding areas will be presented as a background to the problem of land use management in the vicinity of the airport. This paper seeks to address the following questions: if and how airports have affected urban planning in Lodz, does the land use around the airport prevent the development of Lodz Airport, and how has the situation changed over the time? It can be assumed that as a result of lack of experience, land resources and size of investments on one hand and legislative dissonance and peculiar practices on the other, aviation infrastructure in Lodz is designed to meet temporary needs and is characterised by achieving short-term goals. Cyclical problems are solved in an intermittent manner and involve all the municipal resources, so there’s little left to secure long-term investments.

Summary Neoliberal land reforms to increase economic development have important implications for biodiversity conservation. This paper investigates land reform in New Zealand’s South Island that divides leased state-owned stations (ranches) with private grazing leases into state-owned conservation land, private land owned by the former leaseholder and private land under protective covenant (similar to conservation easement). Conserved lands had less threatened vegetation, lower productivity, less proximity to towns and steeper slopes than privatized lands. Covenants on private land were more common in intermediate zones with moderate land-use productivity and slope. Lands identified with ecological or recreational ‘significant inherent values’ were more likely to shift into conserved or covenant status. Yet among lands with identified ecological values, higher-threat areas were more likely to be privatized than lower-threat areas. This paper makes two novel contributions: (1) quantitatively examining the role of scientific recommendations about significant inherent values in land reform outcomes; and (2) examining the use of conservation covenants on privatized land. To achieve biodiversity goals, it is critical to avoid or prevent the removal of land-use restrictions beyond protected areas.

In SWAT and SWAT+ models, the variations in hydrological processes are represented by Hydrological Response Units (HRUs). In the default models, agricultural land cover is represented by a single growing cycle. However, agricultural land use, especially in African cultivated catchments, typically consists of several cropping seasons, following dry and wet seasonal patterns, and are hence incorrectly represented in SWAT and SWAT+ default models. In this paper, we propose a procedure to incorporate agricultural seasonal land-use dynamics by (1) mapping land-use trajectories instead of static land-cover maps and (2) linking these trajectories to agricultural management settings. This approach was tested in SWAT and SWAT+ models of Usa catchment in Tanzania that is intensively cultivated by implementing dominant dynamic trajectories. Our results were evaluated with remote-sensing observations for Leaf Area Index (LAI), which showed that a single growing cycle did not well represent vegetation dynamics. A better agreement was obtained after implementing seasonal land-use dynamics for cultivated HRUs. It was concluded that the representation of seasonal land-use dynamics through trajectory implementation can lead to improved temporal patterns of LAI in default models. The SWAT+ model had higher flexibility in representing agricultural practices, using decision tables, and by being able to represent mixed cropping cultivations.

The accident at the Fukushima Daiichi Nuclear Power Plant has raised questions about the accumulation of radionuclides in soils, the transfer in the foodchain and the possibility of continued restricted future land use. This paper summarizes what is generally understood about the application of agricultural countermeasures as a land management option to reduce the radionuclides transfer in the food chain and to facilitate the return of potentially affected soils to agricultural practices in areas impacted by a nuclear accident.

AbstractThe paper presents the results of a scientific project focused on limiting nutrient losses from farms by introducing measures to apply fertilizers in a more sustainable way. It is a case study of selected aspects of farm management, focussing on the issue of sustainable agriculture and their tools. The main aim of the study was to analyse and evaluate farmers’ knowledge of the fertilizing process and its aspects, as well as applying sustainable agricultural activities on farms. The study emphasised the importance of nutrient management, as very important for sustainable farming. Also, the links between farmers’ opinions and their activities were analysed. The important issue concerned measures for sustainable farm management introduced on the farms, as well as measures to limit nutrient leaching into groundwater. Twenty-eight farmers from two regions in Poland were interviewed about their perceptions for the case study. In general, the farmers considered their farm activities to be more sustainable than in the past. They demonstrated an understanding of the general idea of sustainable agriculture. However, many farmers still demonstrated a poor grasp of nutrient flows and nutrient balances on farms. Their knowledge and perception was based on general, rather than specific knowledge gleaned from an academic/vocational course. The farmers demonstrated a realization that there were some new, or low-cost measures that could be introduced to make management more sustainable and pro-environmental, but there was still a need for wider adoption of sustainable agricultural practices.

Olive growing has been intensified through the simplification of agricultural landscapes. In order to rethink the environmental drawbacks of these practices, conservation biological control techniques have been examined. In this work, Prays oleae and its natural enemy Chrysoperla carnea were monitored to account for the effects of the amount and diversity of different land-uses. We found that C. carnea showed an attraction to areas with high abundances of P. oleae but this predator did not display any affection by the different land-uses. Inversely, P. oleae abundance was lower in diverse landscapes and higher in simplified ones. Importantly, higher abundances of C. carnea were related to lower infestation levels of P. oleae in the late part of the season. These results corroborate the attraction of C. carnea to the olive moth, highlighting the potential of C. carnea as a biological control agent of this pest, assert that the promotion of land-use diversity can reduce P. oleae and confirm that landscapes dominated by olive groves can promote this pest. The present study aims at contributing to the discussion about the management of agricultural ecosystems by providing farmers with sustainable alternatives that do not have harmful effects on the environment and public health.
