Land degradation is increasing in severity and extent in many parts of the world. Success in arresting land degradation entails an improved understanding of its causes, process, indicators and impacts. Various scientific methodologies have been employed to assess land degradation globally. However, the use of local community knowledge in elucidating the causes, process, indicators and effects of land degradation has seen little application by scientists and policy makers. Land degradation may be a physical process, but its underlying causes are firmly rooted in the socio-economic, political and cultural environment in which land users operate. Analyzing the root causes and effects of land degradation from local community knowledge, perception and adapting strategies perspective will provide information that is essential for designing and promoting sustainable land management practices. The main objective of this study was to analyze the perceptions of farmers’ on the impact of land degradation hazard on agricultural land productivity decline associated with soil erosion and fertility loss. The study used a multistage sampling procedure to select sample respondent households. The sample size of the study was 120 household heads and 226 farm plots managed by these farmers. The primary data of the study were collected by using semi-structured Interview, focus group discussions and field observation. Both descriptive statistics and econometric techniques were used for data analysis. Descriptive results show that 57percent of the respondents were perceived the severity and its consequence on agricultural land productivity. The following indicators of soil erosion and fertility loss were generally perceived and observed by farmers’ in the study area: gullies formations, soil accumulation around clumps of vegetation, soil deposits on gentle slopes, exposed roots, muddy water, sedimentation in streams and rivers, change in vegetation species, increased runoff, and reduced rooting depth. The direct human activities which were perceived to be causing land degradation in the study area include: deforestation and clearing of vegetation, overgrazing, steep slope cultivation and continuous cropping. The farmers’ possibility of perceiving the impact of land degradation hazard on agricultural land productivity was primarily determined by institutional, psychological, demographic and by bio-physical factors. Farmers who perceive their land as deteriorating and producing less than desired, tend to adopt improved land management practices. On the other hand, farmers who perceive their land to be fertile tend to have low adoption of conservation practices. In order to overcome this land degradation and its consequent effects, the study recommended a need for the government to enforce effective policies to control and prevent land degradation and these policies should be community inclusive /participatory founded up on indigenous and age-honored knowledge and tradition of farmers' natural resource management as well as introduced scientific practices.

The world is undergoing the largest wave of urban growth in history. More than half of the world’s population now lives in towns and cities, and by 2030 this number will swell to about 5 billion. ‘Urbanization has the potential to usher in a new era of wellbeing, resource efficiency and economic growth. But due to increased population the pressure of demand also increases in urban areas’ (Drakakis-Smith, David, 1996). The loss of agricultural land to other land uses occasioned by urban growth is an issue of growing concern worldwide, particularly in the developing countries like India. This paper is an attempt to assess the impact of urbanization on land use and land cover patterns in Ajmer city. Recent trends indicate that the rural urban migration and religious significance of the place attracting thousands of tourists every year, have immensely contributed in the increasing population of city and is causing change in land use patterns. This accelerating urban sprawl has led to shrinking of the agricultural land and land holdings. Due to increased rate of urbanization, the agricultural areas have been transformed into residential and industrial areas (Retnaraj D,1994). There are several key factors which cause increase in population here such as Smart City Projects, potential for employment, higher education, more comfortable and quality housing, better health facilities, high living standard etc. Population pressure not only directly increases the demand for food, but also indirectly reduces its supply through building development, environmental degradation and marginalization of food production (Aldington T, 1997). Also, there are several issues which are associated with continuous increase in population i.e. land degradation, pollution, poverty, slums, unaffordable housing etc. Pollution, formulation of slums, transportation congestion, environmental hazards, land degradation and crime are some of the major impacts of urbanization on Ajmer city. This study involves mapping of land use patterns by analyzing data and satellite imagery taken at different time periods. The satellite images of year 2000 and 2017 are used. The change detection techniques are used with the help of Geographical Information System software like ERDAS and ArcGIS. The supervised classification of all the three satellite images is done by ERDAS software to demarcate and analyze land use change.

This research has been done to identify changes in agricultural land to non-agriculture causing the establishment of illegal settlements. Viewed from the standpoint of nature this research is descriptive research, carried out in order to help in strengthening old theories or within the framework of developing new theories. Research locations are in the Office of the Regional Planning, Research and Development (BP3D) Boyolali Regency and Boyolali Regency Agriculture Office. Data collection was carried out by interview and literature study. Data analysis technique is done by data reduction, data display and conclusion. The results show that agricultural development will occur if land problems over the conversion of agricultural land into settlements are unavoidable or need to find a solution to a problem that is very urgent, this is by studying the impact of the problem and socializing the community over these impacts and their resolution to obtain clarity of land legality the conversion. When land starts to shrink, domestic food needs will decrease because population growth cannot be avoided every year. For this reason, immediate special handling is needed, such as direct counseling for the community. Will be danger of land conversion is carried out continuously. Development of the latest technology is needed to manage the land so that fertility does not decrease quickly so as to reduce land productivity. Another way replacement of agricultural land which is used as an alternative handling of the legality problem of conversion of agricultural land.


Degradation currently affects 25 % of the land on Earth and 40 % of the agricultural land on Earth. Environmental effects of soil degradation are widespread, including increased soil losses, deterioration of water quality, decline of biodiversity and degradation of ecological resources and associated values, especially where actual land use is disrespectful (natural use in circumstances where land is in conflict with the environment. Changes in temperature, wind velocity, and precipitation patterns can affect the production of plant biomass, land use, land cover, soil moisture, infiltration rate, runoff and crop management, and eventually land degradation. In recent decades, powerful partnerships have been seen between global climate change and land loss processes. In order to reliably define or forecast the effect of climate change on the loss of land, models of climate change and land use models should be combined with hydrology. Until the first seventies land degradation and geological process weren't thought of a serious issue in most Mediterranean regions. Traditional agricultural systems were believed to be able to keep those processes under control. So low priority was appointed to research programmes and comes on eroding and conservation, preference being given to the impact of farm machinery on soil structure and compaction beside the role of organic matter within the soil. To regulate the destruction of soil, it is therefore important to have limited and global strategies and regulations. Land use and land cover changes influence carbon fluxes and GHGs emissions that directly alter atmospherical composition and radioactive forcing properties. Land degradation aggravates greenhouse gas-induced global climate change through the discharge of CO2 from cleared and dead vegetation and thru the reduction of the carbon sequestration potential of degraded land. The present analysis furnishes effects of climate amendment on land degradation.

Abstract Land degradation has been recognized as an important environmental threat in the Moldavian Plateau of eastern Romania. This study was designed to estimate the magnitude of land degradation and to review land management in a small catchment in the Central Moldavian Plateau. Several methods were deployed to estimate soil erosion losses, gully distribution, landslide inventory and reservoir sedimentation rates. Results obtained in the study area of 7,766 ha, of which 31% is arable and 32% native forest, show that the mean value of soil losses by water erosion on agricultural land is 19.0 t ha−1y−1. By adding the woodland contribution, this value significantly decreases to 12.8 t ha−1y−1. Then, a large proportion of land (58%) is covered by landslides. Most of them are shallow and dormant (stable), and the active ones form only ~2% of the total landslide area. Siltation rates determined using 137Cs reflect the impact of land management on deposition patterns in reservoirs. Proper conservation measures were applied over a 20-year time-span from 1970-1990. Since 1991 the contour farming system collapsed and returned to the traditional ‘up-and-down slope’ farming system on very small plots.

Land conversion is a phenomenon of the use of agricultural to non agricultural. This phenomenon appears cause the increase growth of suburban population and the demand for land. It can brings the impact for the community to decrease farmer’s income, the lowering of family food security, the subside employment oppurtunities in agriculture, and the difficulties farmer’s access to land. The farmer in improving household economy do a livelihood strategy that is diversification of livelihood, circular migration, and the transition of livelihood. This paper aim to examine the factors that encourage land conversion and to examine farmer’s livelihood strategies due to land conversion. The method used in this research is quantitive approach with the main instrument questionnaire supported by qualitative approach with in-depth interviews. The results of the research in Palasari village indicate that there are aspects that encourage land conversion in the form of urgent economic needs, low land productivity, external pressure, and knowledge aspects owned by farmers regarding government policy. In addition, for most farmers who have converted agricultural land prefer to switch livelihoods to other sectors. Livelihood transition occurs due to the increasingly narrow land of their farms.Keywords : farm households, land conversion, livelihood strategies ABSTRAK Konversi lahan merupakan suatu fenomena pemanfaatan lahan terhadap lahan pertanian menjadi non pertanian. Fenomena ini muncul disebabkan pertumbuhan penduduk pinggiran kota yang semakin tinggi serta tingginya permintaan terhadap lahan. Hal tersebut tentunya dapat memberikan dampak kepada masyarakat terhadap penurunan pendapatan petani. Petani dalam meningkatkan ekonomi rumah tangga melakukan strategi nafkah yaitu diversifikasi nafkah, migrasi sirkuler, dan peralihan mata pencaharian. Tujuan penelitian ini untuk mengkaji faktor-faktor yang mendorong terjadinya konversi lahan serta mengkaji strategi nafkah rumah tangga petani akibat adanya konversi lahan. Metode yang digunakan yaitu pendekatan kuantitatif dengan kuesioner dan didukung oleh data kualitatif dengan wawancara. Hasil penelitian di Desa Palasari menunjukkan bahwa terdapat aspek-aspek yang mendorong terjadinya konversi lahan berupa kebutuhan ekonomi yang mendesak, produktivitas lahan, tekanan pihak luar, dan aspek pengetahuan petani. Sebagian besar petani yang telah mengkonversi lahan pertaniannya lebih memilih untuk beralih mata pencaharian ke sektor lain. Peralihan mata pencaharian terjadi disebabkan oleh luas lahan pertanian mereka yang semakin sempit.Kata Kunci : konversi lahan, rumah tangga petani, strategi nafkah

Land is an indispensable part of human habitat. In contrast to other modes of production, which wear out during use, lose their useful properties and remove themselves from productive use, natural productive capacity of land is not diminished, but it even increases on the condition of its sustainable use. Consequently, theoretically, it can be considered that land is a lifelong mean of production. Inappropriate land use causes its degradation, reduction of agricultural ground productivity, it means reduction of land price . Agricultural land degradation in Ukraine is quite significant — total area of agricultural land that has destructive impact of water erosion is 13,3 million hectares (32 %), including 10,6 million hectares of arable land. There are 4,5 million hectares with medium — and strongly washed soils within the eroded soil, and 68 hectares completely lost soil horizon. More than 6 million hectares of land systematically suffer of wind erosion. The purpose of the article is to outline the approach to assess the impact of agricultural land degradation on their monetary evaluation, and to measure the loss of land tax, caused by deterioration of land resources as a result of degradation. The following methods were used in solving the tasks: monographic (in the development of scientific publications on environmental and economic principles of land use and protection, regulations on land use, statistical collections); mathematical modeling, economic analysis, determination of relative values, averages, grouping (in the study of factors that cause degradation of land resources). An assessment of the impact of agricultural land degradation on the normative assessment of land and on the land tax was made. The study has demonstrated, that degradation of agricultural land causes significant social-economic damage — reduction of normative monetary evaluation 2,3 times, and annual loss of land tax at the level of 464,5 billion UAH. These indicators make the widespread introduction of measures to combat land degradation and, above all, soil erosion very relevant.

Land use change from agricultural land into non-agricultural land such as for industries, streets, and others has increased erosion impact, nutrient and sediment in a watershed. That process had caused land degradation in a watershed, therefore, land productivity will decrease and even will cause flood during rainy season and drought during dry season. In order to find out what will happen if land use change takes part, a software using BASIC language was arranged. This software is aimed to simulate erosion process easier. This software uses USLE and Snyder in predicting erosion. Additionally, this software is also able to predict sediment delivery.Keywords : Software conservation, language BASIC.

Purpose: The better management of land resources is essential for sustainability and for improving the quality of life of people living in the city and the peri urban areas who are mostly farmers With major changes being agricultural land use giving way to residential land use in the peri urban area, access to agricultural land is drastically reduced causing food insecurity problems in the region. The general objective of the study was to establish the access the impact of human population on land degradation. Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps. Findings: The study found out that increase in human population has resulted to more land-use and land cover changes are likely to take place as more land is converted over time, forest to agricultural land, and agricultural land to built-up land, which threatens the existence of agricultural land and water sources in the future. Recommendations: The study recommends that there is the need for stakeholder participation and institutionalize stakeholders’ participations in land use planning process and urban planning. It is only when the public and land owners are well informed about land management issues that a positive change of attitude, adherence to laws on land use among others can be achieved. The county government and the national governments should come up with policies to outlaw arbitrary sale of land especially in areas where the main form of land use is agriculture to enhance the effectiveness of zoning regulations. It is important that the management of land be made the first priority in the study area and the nation as a whole. The various land sector agencies and institutions responsible for land management should enforce the existing laws on land management
