Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.

Tapaktuan is a region of the west coast of Aceh which has high forest and biodiversity potential in Indonesia because most of this region is part of the Leuser Ecosystem which is known to have high biodiversity and needs to be preserved. land conversion is a big challenge for this region because of development and development activities as well as population growth. The purpose of this study is to identify land use using GPS devices. The method is by first grounding the field with GPS MAPS GARMIN type 60 CSx then the data is stored on the device. Next determine the position of the object points and then input using Mapsource software to be processed into ArcGIS. to obtain information in the field in the form of observations of land cover in the field and the coordinates. Based on the results of groundchek observations in the field as many as 299 points obtained 7 types of land cover in the field consisting of bodies of water, forests, plantations, dryland agriculture, vacant land, settlements, and shrubs. The coordinates were taken covering 15 villages in the Tapaktuan sub-district, South Aceh Regency.

The Impact

Footprints are powerful indicators for evaluating the impact of the bioeconomy of a country on environmental goods, domestically and abroad. In this study, we apply a hybrid approach combining a Multi-Regional Input-Output model and land use modelling to compute the agricultural land footprint (aLF). Furthermore, we added information on land-use change to the analysis and allocated land conversion to specific commodities. The German case study shows that the aLF abroad is larger by a factor of 2.5 to 3 than the aLF in Germany. In 2005 and 2010, conversion of natural and semi-natural land-cover types abroad allocated to Germany due to import increases was 2.5 times higher than the global average. Import increases to Germany slowed down in 2015 and 2020, reducing land conversion attributed to the German bioeconomy to the global average. The case study shows that the applied land footprint provides clear and meaningful information for policymakers and other stakeholders. The presented methodological approach can be applied to other countries and regions covered in the underlying database EXIOBASE. It can be adapted, also for an assessment of other ecosystem functions, such as water or soil fertility.

SUMMARYEffective conservation planning must anticipate the rates and patterns of dynamic threats to biodiversity, such as rapid changes in land use. Poor understanding and prediction of drivers and patterns of conversion of habitat can hinder assessments of the relative vulnerability of areas of remaining indigenous habitat to conversion, and identification of habitats in most immediate need of protection. Methods developed to model vulnerability to conversion vary in their complexity and applicability to conservation management. Generalized additive models provide a simple robust method to explore predictors and patterns of land-use conversion, and may be used to predict future patterns of conversion using recent land conversion data. This paper provides the first data-derived and statistically validated measurement of the vulnerability of New Zealand's indigenous grasslands to conversion. Higher altitude and more marginal (for agriculture and forestry) land showed greater conversion, and models based on earlier conversion patterns performed more poorly in predicting current patterns of conversion. Up-to-date land conversion data appear crucial for accurately predicting future vulnerability to habitat conversion.

The Impact

Footprints are powerful indicators for evaluating the impacts of a country’s bioeconomy on environmental goods, both domestic and abroad. We apply a hybrid approach combining a multi-regional input-output model and land use modelling to compute the agricultural land footprint (aLF). Furthermore, we added information on land-use change to the analysis and allocated land conversion to specific commodities. Using Germany as a case study, we show that the aLF abroad is 2.5 to 3 times larger compared to impacts within the country. When allocating land conversion of natural and semi-natural land-cover types in 2005 and 2010 to import increases by Germany, conversion rates were found to be 2.5 times higher than for the global average. Import increases to Germany slowed down in 2015 and 2020, reducing land conversion attributed to the German bioeconomy as well. Our results indicate that looking at a static import pattern is not sufficient to draw a realistic picture of the land footprint of a country. For a more detailed assessment that also considers temporal dynamics and impacts of biomass use and trade, our newly developed set of indicators also captures changes of import patterns over time. The case study shows that our enhanced land footprint provides clear and meaningful information for policymakers and other stakeholders.

Significant Factors

Tangerang District is one of the rice producers in Banten Province. The intensification of rice production is one of the solutions due to the agricultural land conversion problem in Tangerang. The purpose of this study is to analyze the farmer perception about subsidized fertilizer and we also analyze the effect of land use and subsidized fertilizer for rice production at the farmer level in Tangerang. The data used in this study were collected through an interview survey using a structured questioner to 35 respondents in Tangerang in 2016. The data were analyzed using descriptive and quantitative analysis. The result showed that the farmers perceive that the availability of subsidized fertilizer is frequently rare especially for nitrogen fertilizer and phosphorus fertilizer. The study also shows the rice production at the farmer level was affected by land use, the application of subsidized urea fertilizer, the application of organic fertilizer, and the application of returning the straw to the paddy field. All of these significant factors on rice production were inelastic in the short term and long term. It is important to decrease agricultural land conversion and returning the straw to the paddy field to maintaining rice production in Tangerang.
