2.1 Descrição curta da tecnologia

Definição da tecnologia:

A scenario simulation of land use change where high-quality inner urban development is promoted, including the rehabilitation of brownfields, reuse of vacant lots, use of gaps between buildings and the improvement of existing structures.

2.2 Descrição detalhada da tecnologia

Descrição:

The best means of reducing land loss by settlement and infrastructure development is through fulfilling inner urban development potential. This “compact settlement development” makes the most efficient use of space. Simultaneously it contributes to the reduction of greenhouse gas emissions by the maintenance of farmland or forest areas on the outskirts of urban areas. One example is the rehabilitation and utilization of “brownfields”, including previous industrial areas. Another example is redevelopment of transportation infrastructure within settlements or on the urban fringe. However, the revitalization and utilization of brownfields is often expensive. Other aspects of inner urban development are the reuse of vacant lots, the use of spaces between buildings and the improvement of existing building structures by adding extra floors.

Purpose of the Technology: Through these developments, the rate of daily land consumption by settlement and transportation can be reduced. In Germany, such land loss reached 73 ha/day in 2010. According to a survey commissioned by the Federal Office for Building and Regional Planning, 20% of existing brownfields and vacant lots can be brought into use in the short term and another 50% of the total in the long term: 30% cannot be developed for various reasons including disputed tenure. The ambitious aim of the sustainability strategy of the German federal government is to reduce today’s daily land consumption for settlement and transport from the current 73 ha/day to 30 ha/day by 2020. However this appears unrealistic: nevertheless with high-quality inner urban development technology, this could be achieved by 2030. If the technology is planned and implemented through scenario simulation of sectoral land use changes in Germany (agriculture, forest and settlements), then calculations show that the daily land loss by settlement and transport could be reduced from 45 ha/day in a “business as usual” scenario (with some improvements assumed) to 30 ha/per day in 2030 by using high-quality inner urban development measures.

Establishment / maintenance activities and inputs: During re-densification of urban areas sufficient green spaces must be protected to address climate change considerations such as higher temperatures and more runoff. High urban densities lead to an increase in the “heat island effect” (a combination of extensive urban/ suburban landscapes with reduced air circulation, little cloud cover and long periods of high temperature). Thus, the rehabilitation of brownfields has to go along with the transformation of impervious surfaces into permeable ones, and planning of corridors for air exchange by “green and blue climate corridors” (public parks, ponds and rivers). There are several initiatives to establish high quality inner urban development in Germany. These include: 1) “Inner before external” urban development within the Federal Building Law; 2) Many communities operating a brownfields and vacant lots cadastre; 3) General management of urban areas. Nevertheless, the reuse of inner city brownfields often requires considerable and costly remediation of contaminated sites. Due to the ownership issues of vacant lots, many are not easily accessible through municipalities, and this complicates their development. In other cases, available construction areas or buildings are not appropriate to the needs of investors.

3.2 Tipo(s) atualizado(s) de uso da terra onde a tecnologia foi aplicada

Comentários:

Major land use problems (compiler’s opinion): Land use for settlement and transport leads to imperviousness, and a reduction of high quality agricultural areas. Sealed surfaces increase runoff during heavy rain events, and high building densities promote the development of urban heat islands.

Major land use problems (land users’ perception): In fast-growing regions, high demand requires the supply of additional land for construction.

4.7 Fatores mais importantes que afetam os custos

Descreva os fatores mais determinantes que afetam os custos:

Measures can be very different in terms of inputs and costs, and depend on the specific situation eg contaminated area of a former petrol station can have very high rehabilitation costs due to the need to detoxify the soil before new use. However other measures cost (effectively) no money at all eg legislation governing the reduction of the distance permitted between two new buildings by the local authorities.

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do compilador ou de outra pessoa capacitada
Scenario simulations help to identify hot spots and can indicate regions where inner urban development should be pushed by public institutions. How can they be sustained / enhanced? Inner urban development is profitable if pressure on land is high but needs to be pushed also in regions with less pressure to protect soils, nature and climate.
Inner urban development can have positive impacts on climate adaptation How can they be sustained / enhanced? To reach positive impacts on climate adaptation issues it is necessary to establish green and blue climate corridors (e.g. network of urban greens established or optimized by re-vitalization of brownfields).
Inner urban development can rise the attractiveness of town (greater inner city mobility, compact town) How can they be sustained / enhanced? The technology improves inner-urban area development. For improvements to existing settlement areas, additional building activities (e.g. making buildings taller; concentrating housing) are possible. Side effects are a very concentrated settlement structure but with the advantage of reducing the sprawling out of settlements into agricultural land or wooded areas (i.e. outer development) and this saves GHG emissions and other ecosystem services ESS.

6.8 Pontos fracos, desvantagens/riscos da tecnologia e formas de superá-los

Pontos fracos/vantagens/riscos na visão do compilador ou de outra pessoa capacitada	Como eles podem ser superados?
Nationwide simulation cannot indicate concrete lots where inner urban development should be pushed.	The technology has shown the potential for Germany as a whole, but implementation depends on local authorities.
