Green City

The development of an urban area needs to pay attention to the environmental carrying capacity. One of the way to achieve sustainable urban development is to apply one of the attributes of green city namely green open space (GOS). The purpose of the research are to analyze the types of land use in the years of 2010 and 2017, to analysis land use changes from 2010 to 2017, predicting land use change, analyzing the adequacy of GOS by area acreage and population number, and to determine the direction of GOS development in the Jember City.The research was conducted in the Capital of Jember Regency, namely Jember City with the total area of 9,900 ha. Methods of data analysis are the spatial analysis, analysis of population growth with quadratic growth model, Cellular Automata-Markov, and synthesis of green open space (GOS) development direction based on potential land and the value of the land. The results showed that there are ten types of land use in the Jember City, those are forest, mixed gardens, dryland agriculture, open land, cemetery, plantation, settlements and buildings, paddy fields, shrubs and grasses, and river. A relatively large land use changed in the period of 2010-2017 were dryland agriculture and paddy fields into settlements and buildings. The results of land use prediction with Cellular Automata-Markov described the trend of land use change becomes settlements (buildings) and plantations. The adequacy of public GOS by area as well as population still lacking whereas the adequacy of private GOS has been exceeded. The GOS acreage based on number of population is lower than those GOS based on an area. The GOS development planning is required to fulfill the needs. The consideration used to draw up the directives is the existing land use, regional spatial plan (RTRW), prediction of land use in the year of 2024, distribution of GOS, and land values. Development plans of GOS consist of two stages namely stage 1 and stage 2 with three priorities, namely priority 1, priority 2, and priority 3 with the total area 1,052 ha and funding require approximately two trillion rupiahs. The acreage of potential land for development of GOS has already enough to fulfill the needs of GOS based on population, however, not yet sufficient to fulfill the needs of GOS based on regency area.

Southern New Zealand has seen major changes in land use in the past 20 years with the rise in dairy cows in milk from 149 000 in 1994 to 682 000 in 2010, while breeding ewe numbers have declined from 11.2 million to 7.3 million over the same period. The development of milking platforms with a significant need for winter dairy grazing has opened up many opportunities for sheep, beef and deer farmers in the region. The need to remain profitable, displacement of sheep to more marginal land, and social influences such as retaining family ownership have encouraged farmers to make the most of potential land-use change opportunities. Three case studies outline the changes made and potential profitability increases in dairy conversion, flexible sheep and beef operations and improved deer production, with cash surplus after expenses being more than doubled in each case. Keywords: land use, profit, dairy, sheep, beef, deer.

The focus of this article is on the potential land use change impacts associated with the oilseed-based biodiesel consumption. The three main crops used for biodiesel production to date are oilseed rape (OSR), soybeans and oil palm. Therefore, the objective of this paper is to provide a technical assessment of potential land use change arising from the growth of these three major crops at global level, obtained through a broad country-level analysis for their respective major producing countries. The article presents an historical data analysis, evaluating the interaction between the expansion and contraction of these three crops over the last three decades (with a closer look from 2008) together with the carbon stock changes to the land. We categorise the land use by its carbon stock and resulting carbon stock changes from land use change. Crops aimed at the production of ethanol, such as maize (corn), sugarcane, wheat, cassava and sugar beet, although extremely relevant for biofuel policies, are not the subject of this present study. While we did not know at the time of writing this report how the term “significant” would be defined in the EU delegated act we concluded from the analysis of the historical data and using the high ILUC-risk definition as it stands, that the emissions associated with palm and soy are significant. For oil palm, we take Indonesia and Malaysia as proxy for the global position. We calculate an average expansion of 29% on high carbon stock land. For soy, we calculate a global average of 19% expansion. We calculate the global average greenhouse gas emissions intensities based on the ILUC-risks as 56 gCO2eq/MJ for soy oil and 108 gCO2eq/MJ for palm oil. Future projections (OECD-FAO, 2017) suggest these numbers could drop significantly. We do not find evidence for high ILUC-risk expansion of oilseed rape.

Along with the development of Batu City as a tourist city, it is feared that there will be an increase in land use conversion from apple orchards and other agricultural land into residential and tourism land. The rate of land use change must be controlled to maintain environment sustainability. One of the effort is studying the change that occurred in the past few years. The purpose of this study were to observe land use change pattern that occured in 2006, 2012, and 2018, and to predict the land use at 2030 in Batu City. Land use prediction was evaluated with Markov – Cellular Automata models. The analysis showed that forest area decreased up to 5% and the built area increased up to 5.2% from 2006 to 2018. Prediction of land use in 2030 showed that there will be a decrease in forest, agriculture, and bareland areas, and an increase in shrubs and built areas. Agricultural land needs to be directed to be protected or conserved, while shrubs and open land need to be directed into potential land for apple orchards development in Batu City.

Objective: This article describes and analyzes the main concepts of coastal ecosystems, these as a result of research concerning land-use change assessments in coastal areas. Design/Methodology/Approach: Scientific articles were searched using keywords in English and Spanish. Articles regarding land-use change assessment in coastal areas were selected, discarding those that although being on coastal zones and geographic and soil identification did not use Geographic Information System (GIS). Results: A GIS is a computer-based tool for evaluating the land-use change in coastal areas by quantifying variations. It is analyzed through GIS and its contributions; highlighting its importance and constant monitoring. Limitations of the study/Implications: This research analyzes national and international scientific information, published from 2007 to 2019, regarding the land-use change in coastal areas quantified with the digital GIS tool. Findings/Conclusions: GIS are useful tools in the identification and quantitative evaluation of changes in land-use in coastal ecosystems; which require constant evaluation due to their high dynamism.

Conversion of native vegetation into farmed grassland in the Lake Taupo catchment commenced in the late 1950s. The lake's iconic value is being threatened by the slow decline in lake water quality that has become apparent since the 1970s.
