Nutrient recycling from sanitation and energy systems to the agroecosystem - Ecological research on case studies in Karagwe, Tanzania

Krause, Ariane ; Kaupenjohann, Martin ; George, Eckhard ; Köppel, Johann (2015)

Open cycles of organic carbon and nutrients cause soil degradation. Procedures such as ecological sanitation (EcoSan), bioenergy and Terra Preta practice (TPP) can contribute to closing nutrient cycles and may, in addition, sequester carbon. This paper introduces three projects in Karagwe, Tanzania, and their applied approach of integrated resource management to capture carbon and nutrients fro...

Organic wastes from bioenergy and ecological sanitation as a soil fertility improver: a field experiment in a tropical Andosol

Krause, Ariane ; Nehls, Thomas ; George, Eckhard ; Kaupenjohann, Martin (2016)

Andosols require the regular application of phosphorus (P) to sustain crop productivity. On an Andosol in NW Tanzania, we studied the short-term effects of amending standard compost, biogas slurry and CaSa compost (containing biochar and sanitized human excreta) on (i) the soil's physico-chemical properties, on (ii) biomass growth and crop productivity, and on (iii) the plants' nutrient status....

Reducing global CO2 emissions with the technologies we have

Ward, Hauke ; Radebach, Alexander ; Vierhaus, Ingmar ; Fügenschuh, Armin ; Steckel, Jan Christoph (2017)

The energy intensities of the various industrial sectors differ considerably across countries. This suggests a potential for emissions reductions through improved accessibility to efficient technologies. This paper estimates an upper-bound CO2 emission mitigation potential that could theoretically be achieved by improved access to efficient technologies in industrial sectors. We develop a linea...

Ward, Hauke ; Burger, Mia ; Chang, Ya-Ju ; Fürstmann, Paul ; Neugebauer, Sabrina ; Radebach, Alexander ; Sproesser, Gunther ; Pittner, Andreas ; Rethmeier, Michael ; Uhlmann, Eckart ; Steckel, Jan Christoph (2016)

Evaluating innovative process technologies has become highly important within the last decades. As standard tools different Life Cycle Assessment methods have been established, which are continuously improved. While those are designed for evaluating single processes they run into difficulties when it comes to assessing environmental impacts of process innovations at macroeconomic level. In this...

Truncation Error Estimates in Process Life Cycle Assessment Using Input‐Output Analysis

Ward, Hauke ; Wenz, Leonie ; Steckel, Jan Christoph ; Minx, Jan (2017)

Process life cycle assessment (PLCA) is widely used to quantify environmental flows associated with the manufacturing of products and other processes. As PLCA always depends on defining a system boundary, its application involves truncation errors. Different methods of estimating truncation errors are proposed in the literature; most of these are based on artificially constructed system complet...

The effect of industry delocalization on global energy use: A global sectoral perspective

Forin, Silvia ; Radebach, Alexander ; Steckel, Jan Christoph ; Ward, Hauke (2018)

Sectoral production technologies differ largely across countries, so do sectoral energy intensities. Hence, shifts in production locations within global sectors, possibly caused by environmental regulations, are likely to have an impact on aggregated energy usage and emissions. Applying a Logarithmic Mean Divisia Index decomposition we decompose changes of sectoral energy use from 2001–2011 int...

Valuing wastes

Krause, Ariane (2019)

My dissertation had as its starting point the intention of two Tanzanian farmer's initiatives and their German partners to disseminate sustainable cooking and sanitation technologies to smallholder households in Karagwe District, in northwest Tanzania (TZ). These locally developed and adapted technologies include improved cook stoves, such as microgasifiers, and a system combining biogas digest...

Urban climate and heat stress: how likely is the implementation of adaptation measures in mid-latitude cities? The case of façade greening analyzed with Bayesian networks

Sprondel, Nora ; Donner, Julie ; Mahlkow, Nicole ; Köppel, Johann (2016)

Background Urban heat is a challenge for mid-latitude cities possibly aggravated by global climate change making it necessary to adapt the urban fabric. Façade greening has been identified as an important measure to adjust the building stock and new buildings to adverse climatic impacts. Yet, little is known on factors that influence implementation probabilities for adaptation measures. Theref...

To Pay or Not to Pay: Competing Theories to Explain Individuals’ Willingness to Pay for Public Environmental Goods

Liebe, Ulf ; Preisendörfer, Peter ; Meyerhoff, Jürgen (2010)

Several theories have been proposed in an attempt to explain individuals’ willingness to pay (WTP) for public environmental goods. While most studies only take into account a single theory, this article discusses competing theories. These include, in addition to a basic economic model, the theory of public goods, Ajzen’s theory of planned behavior, and Schwartz’s norm-activation model. Empirica...

Choudhury, Nirmalya ; Banerjee, Parthosarathy ; Roy, Dayabati (2009)

This article studies the role played by the constitutionally empowered Panchayati Raj Institutions over a large irrigation system in West Bengal. The article tries to capture the linkages and the dynamics governing interaction between the 'Gram Panchayats' and the Water User Associations. The inferences are drawn from observed phenomenon pertaining to the role and relationship between the two s...

Die Rolle der nicht-hoheitlichen Flächensicherung im Naturschutz

Disselhoff, Tilmann (2018)

The control of land uses for nature conservation purposes is implemented through regulatory instruments (land use planning, designation of reserves etc.) and through voluntary contractual agreements. The pursuit of conservation goals through voluntary instruments (acquisition of properties, voluntary use restrictions etc.) can be summarized as private land conservation. Private land conservati...

Indicators on the Impacts of Climate Change on Biodiversity in Germany—Data Driven or Meeting Political Needs?

Schliep, Rainer ; Walz, Ulrich ; Sukopp, Ulrich ; Heiland, Stefan (2018-10-31)

When developing new indicators for policy advice, two different approaches exist and may be combined with each other. First, a data-driven, bottom-up approach determines indicators primarily by the availability of suitable data. Second, indicators can be developed by a top-down approach, on the basis of political fields of action and related normative goals. While the bottom-up approach might n...

The future of global land use

Kreidenweis, Ulrich (2018)

Global land-use change is a main driver of two of the biggest environmental alterations threatening human well-being: climate change and the decline in biodiversity. Over recent decades, a growing and wealthier population has requested more agricultural products, and this demand has been satisfied by expanding agricultural areas and intensifying production. However, this has posed consequences....

Driving forces and barriers for adaption strategies against the urban heat stress hazard in Berlin, Germany

Donner, Julie (2018)

Climate change is here and mitigation efforts will not be enough to stop it. We need to adapt to its unavoidable impacts. At the same time, increasing anthropogenic influence on urban climates is leading to worsening urban heat stress. Increased amounts of impervious area, dark surfaces, and the barrier effect of large buildings reduce the ability of especially dense, inner-city areas to cool t...

The scenario family is characterized by rapid and fossil-fueled development with high socio-economic challenges to mitigation and low socio-economic challenges to adaptation (SSP5). A special focus is placed on the SSP5 marker scenario developed by the REMIND-MAgPI...

The role of efficient technology for achieving climate change mitigation and development

Ward, Hauke (2018)

This thesis is motivated by a potential conflict within the sustainable development goals, which refers to climate change mitigation and development. This conflict is of special relevance for developing countries. On the one hand these are projected to be most severely impacted by climate change. On the other hand fast economic development, connected to emitting greenhouse gases, could help sub...
