Dpsir Approach

Increasing land use pressure is a primary force for degradation of agricultural areas. The drivers for these pressures are initiated by a series of interconnected processes. This study presents a novel methodology to analyze drivers of changing land use pressure and the effects on society and landscape. The focus was on characterizing these drivers and relate them to land use statistics obtained from geospatial data from the important semiarid Merguellil Wadi between 1976 and 2016. Cause-and-effect relationships between different drivers of land use change were analyzed using the DPSIR approach. Results show that during the 40-year period cultivated land increased and wetland areas decreased substantially. Drivers for change were pressure from economic development, cultivation practices, and hydro-agricultural techniques. This leads to stress on water and soil resulting in soil erosion, poverty increase, and rural exodus. We show that hydro-agricultural techniques adapted to the semiarid climate, allocation of land property rights, resource allocation, and improved marketing of agricultural products can help rural residents to diversify their economy, and thus better preserve the fragile semiarid landscape. Results of this study can be used to ensure sustainable management of water and soil resources in areas with similar climate and socio-economic conditions.

Annotation. The basis of food security for the country and its regions is to ensure optimal food production and economic affordability. The purpose of the article is to identify ways to increase the production of high quality food and to ensure economic accessibility to the population of Ukraine in the purchase of food. As the volume of production of the most important foodstuffs per person is low, it is essential to increase the volume of production of agricultural products and their processing, to ensure economic accessibility to the population in the purchase of foodstuffs, for which it is necessary to develop a long-term program of agro-industrial development in the country. complex, reform the agrarian sector of the economy, create a land service for the control of land resources and develop its structure: cr vine farms, farms, private farms and cooperatives, run a transparent market of agricultural land, where the owners, land owners must be citizens of Ukraine, to provide comprehensive state support to producers of the agricultural sector to ensure economic conditions of accessibility in public purchasing food.

Transformation Stage

one of the basic directions of the long-term development of the agro-industrial complex is the implementation of measures for import substitution of agricultural products and food, increasing the high rate of export potential of the industry. At the same time, it is necessary to solve the problem of increasing to a rational level the consumption of basic types of food products in groups of the population with a relatively low level of income. The solution of these problems will require new approaches to the economic conditions of functioning of agriculture, its spatial de-velopment, cooperation, social arrangement of rural areas.

The study estimated annual and temporal variation in per capita Land Use/Land Cover Change (LULCC) in Makurdi, Northcentral Nigeria. A total of four Landsat TM/ETM+ images were acquired in April of 1991, 1996, 2001 and 2006 for the study. A total of five LULC types namely water, forest, undergrowth/wetland, cultivated land and built-up land were derived from the Landsat images using supervised classification method. The per capita LULCC was derived by dividing the areas of LULC types by the actual population data. The result showed that built-up land recorded the highest long-term gain in area by 179km2 (130%), with an increment of 8.7% per anum, and undergrowth/wetland lost 119km2 (32%) in area with a decrease of 2.1% per annum from 1991 to 2006. The per capita LULCC of built-up land has increased from 575m2/person (1991) to 1059m2/person (2006), representing an increment of 481m2/person (83%). The undergrowth/wetland recorded the highest decrease in per capita LULCC from 1542m2/person (1991) to 836m2/person (2006), representing a decline by 706m2/person (46%). The study concludes that undergrowth/wetland is the most vulnerable LULC type due to urbanisation, and sustainable urban planning should be practised to conserve the natural cover materials in the study area.

Agrarian Structure

The growth of modern systemic challenges in the context of globalization and integration processes leads to the creation of an effective regional agrarian structure, as one of the most pressing problems of scientific research in economic and social forecasting. The formation of an effective modern agrarian structure and the prospects for its long-term development will largely be determined by state policy, the institution of selective structural support for the state. The agrarian policy of the state to improve the institutional agrarian structure in the region on the basis of foreign and domestic experience should: - contribute to the growth in the number of family peasant farms in all sub-sectors of agriculture in all territories of the region; - create favorable economic conditions that stimulate the economy to create consumer (service) cooperatives of various specializations; - to economically stimulate large agro-industrial formations to interact with small forms of agribusiness. The conceptual directions and mechanisms of the long-term development of the agrarian structure in the Central Chernozem Region are defined, which include goals, stages, principles and objectives of the long-term development of the agrarian structure in the region, legal regulation, financial support, innovative development, the development of markets for agricultural products measures to implement the concept.

The Impact

One of the major environmental issues currently facing New Zealand is that of the sustainability of pastoral farming on North Island hill country. To be sustainable, a system must be resource conserving, environmentally compatible, socially supportive and commer-cially competitive. The Resource Management Act defines sustainable management as managing the use, development and protection of natural and physical resources in a way, or at a rate, which enables people and community to meet their needs without unduly compromising the ability of future generations to meet their needs. Evidence shows that at present this is not so for some hill country, for reasons of on-site land degradation and soil loss, and off-site sediment loading. Socioeconomic sustainability is also in doubt through deterioration in rural infrastructure and social services and steadily decreasing average returns for produce. In the long term there is no conflict between environmental and economic sustainability. The major conflict arises in the short term when the environmental needs of the community can conflict severely with the economic survival of the individual land holder. Adoption of sustainable management will require a much greater understanding of the dynamic interaction between land resources and land use practices and improved matching of land uses with inherent soil and climatic properties. A quantitative understanding of the relationship between biophysical stability of our land resources and their productive capability is required. This paper attempts to: (i) examine how biophysical indicators could be used to quantify the impact of current land use on the productive capability of our hill land resource, and in so doing identify several critical issues facing hill country farmers, and (ii) discuss some of the possible solutions to what we see are currently unsustainable farming practices. It is our contention that the adoption of sustainable management practices will ensure the long-term viability of this sector of the pasture industry and not, as many suggest, its demise.

A warm welcome to our "World of Difference" to all delegates attending this conference - we hope your stay is enjoyable and that you will leave Central Otago with an enhanced appreciation of the diversity of land use and the resilient and growing economic potential that this region has to offer. Without regional wellbeing the national economy will struggle to grow, something Central Government finally seems to be realising, and the Central Otago District Council Long Term Plan 2012-2022 (LTP) signals the importance of establishing a productive economy for the local community which will aid in the economic growth of the district and seeks to create a thriving economy that will be attractive to business and residents alike. Two key principles that underpin the LTP are sustainability and affordability, with the definition of sustainability being "… development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Way

The contemporary condition of soil cover in Ukraine is characterized. The attention is focused onto widespread degradation processes in soils. The causes that determine the development of these negative processes are considered. The contemporary informational support for the condition of soil cover in Ukraine is estimated. In general, the current available information is of narrow-departmental nature, obtained by different methods and non-correlated monitoring programs. As a rule, it is stored in under-structured databases, incompatible with other information systems; mainly recorded on paper media unusable with modern technologies, whereby such information resources are diffi cult to be compiled together. These disadvantages are strong constraints against consistent usage of materials for evaluation, forecast and management of changes in the soil cover. The Soil Observation program should thereby be combined with Agrochemical Passportization and ecology-ameliora- tive monitoring; in other words, the application of innovative soil-agrochemical methodology is considered. Each individual type of surveys shall complement the others, and taken altogether, they shall constitute a con- sistent Information System, capable of solving the problems of assessing the condition, forecasting, manage- ment, usage and protection of soil resources. The monitoring procedures should be conducted on the basis of a new soil concept in line with unifi ed programs and methods, so as to meet European approaches to the maxi- mum extent. Such a technical composition enables getting information on present-day processes in soils, and is the only combination that actually helps us to “ecologize” our knowledge of soils, which is the leading trend in the scope of global soil-science. Thus obtained results will serve as a State-owned tool which would subse- quently facilitate the use and protection of soil resources all over the country, to be involved in a united global soil-information scope. The attention is focused onto social signifi cance of the information on soils and their fertility in terms of land resources optimization, as well as the formation of sustainable land use in Ukraine. Aim. To demonstrate the long-term effect of different ways of tillage of typical low-humus chernozem on the change in humus content and composition and the direction of transformation processes of organic fertili- zers. To study the changes in the structure of energy reserves in group and fractional composition of humus in typical low-humus light-loamy chernozem of the Forest-Steppe of Ukraine. Methods. Field, laboratory, microbiological, computational, mathematical and statistical. Results. It was determined that in conditions of long-term subsurface tillage the most effi cient humus accumulation occurs in the 0–20 cm layer of chernozem with simultaneous increase in its content in the lower part of the processed layer without any accumulation differentiation. Surface tillage leads to expressed differentiation in humus accumulation in the 0–20 cm layer of soil (0.005 % per year). When 6 t/ha of humus are replaced by 7 t/ha of by-products the intensity of humus accumulation is decreasing regardless of the way of tillage, but humus accumulation was found to be the most effi cient for subsurface tillage. The application of subsurface tillage leads to the increase in the ratio of C HA : C FA , which is conditioned by the increase in the humifi cation of plant remains of by-products in the 0−20 cm layer of soil by 110–112 % – for subsurface tillage, and by 105 % – for surface tillage. Conclusions. It was established that systematic subsurface tillage of typical chernozem of the Left-Bank Forest-Steppe of Ukraine leads to the structuring both of the total reserves of energy С org , and its quality content, aimed at the increase in the intensity of the processes of humifi cation and accumulation of organic carbon, and the decrease in miner- alization. The ratio of energy reserves С org of humic acids to fulvic acids in the 0−30 cm layer of chernozem is 1.85−1.87 regardless of the way of tillage, which testifi es to the repeatability of humus accumulation, but the total reserves of energy С org was higher for subsurface tillage (+ 31 Teracalorie/ha) compared to deep plough- ing. As for the surface tillage, the energy enrichment was at the level of deep ploughing.

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.
