Constructing a Credible Estimation for Overreporting of Climate Adaptation Funds in the Creditor Reporting System

  • Janos Borst
  • Dr. Thomas Wencker
  • Dr. Andreas Niekler

Development funds are essential to finance climate change adaptation and are thus an important part of international climate policy. How ever, the absence of a common reporting practice makes it difficult to assess the amount and distribution of such funds. Research has questioned the credibility of reported figures, indicating that adaptation financing is in fact lower than published figures suggest. Projects claiming a greater relevance to climate change adaptation than they target are referred to as “overreported”. To estimate realistic rates of overreporting in large data sets over times, we propose an approach based on state-of-the-art text classification. Additionally, we propose a method that incorporates evidence of smaller, higher-quality data to correct predicted rates using Bayes’ theorem. This enables a comparison of different annotation schemes to estimate the degree of overreporting in climate change adaptation.

Simulating Changes in Hydrological Extremes—Future Scenarios for Morocco

This paper presents a comprehensive river discharge analysis to estimate past and future hydrological extremes across Morocco. Hydrological simulations with historical forcing and climate change scenario inputs have been performed to better understand the change in magnitude and frequency of extreme discharge events that cause flooding. Simulations are applied to all major rivers of Morocco, including a total of 16 basins that cover the majority of the country. An ensemble of temperature and precipitation input parameter sets was generated to analyze input uncertainty, an approach that can be extended to other regions of the world, including data-sparse regions. Parameter uncertainty was also included in the analyses. Historical simulations comprise the period 1979–2021, while future simulations (2015–2100) were performed under the Shared Socioeconomic Pathway (SSP) 2–4.5 and SSP5–8.5. Clear patterns of changing flood extremes are projected; these changes are significant when considered as a proportion of the land area of the country. Two types of basins have been identified, based on their different behavior in climate change scenarios. In the Northern/Mediterranean basins we observe a decrease in the frequency and intensity of events by 2050 under both SSPs, whereas for the remaining catchments higher and more frequent high-flow events in the form of flash floods are detected. Our analysis revealed that this is a consequence of the reduction in rainfall accumulation and intensity in both SSPs for the first type of basins, while the opposite applies to the other type. More generally, we propose a methodology that does not rely on observed time series of discharge, so especially for regions where those do not exist or are not available, and that can be applied to undertake future flood projections in the most data-scarce regions. This method allows future hydrological hazards to be estimated for essentially any region of the world.

Human Rights in German Development Policy. Part 2: Implementation and Effectiveness of the Human Rights-Based Approach in the Area of Action "Private Sector and Financial System Development"

  • Dr. Jan Tobias Polak
  • Dr. Angela Heucher
  • Lea Smidt
  • Lena Taube

Human rights are a "guiding principle" and "quality criterion" of the work of Germany's Federal Ministry for Economic Cooperation and Development (BMZ). This strategy is based on a human rights-based approach (HRBA) that has been comprehensively assessed for the first time in this evaluation. The second part of the evaluation looks at the mainstreaming of human rights standards and principles in bilateral projects of German development cooperation and at the effectiveness of these efforts in partner countries in terms of human rights.

Unter erschwerten Bedingungen. Entwicklungszusammenarbeit in fragilen Staaten

  • Prof. Dr. Jörg Faust
  • Dr. Alexander Kocks
  • Dr. Thomas Wencker

Fragile Staaten gelten als der anspruchsvollste Kontext für eine wirksame und nachhaltige Entwicklungszusammenarbeit (EZ). Vor diesem Hintergrund fasst dieser Themenschwerpunktbericht wesentliche Erkenntnisse DEval´s Evaluierungsarbeit zusammen, ergänzt um Beiträge von renommierten Entscheidungstragenden und Expert*innen aus Wissenschaft, Politik und Implementierungspraxis. Wir hoffen, dass diese Erkenntnisse und Erfahrungen von Nützlichkeit sind und einen Beitrag zu Verbesserungen in unserem Politikfeld leisten werden.

The Promotion of Sustainable Supply Chains through German Development Cooperation based on the Example of the Textile Sector

  • Dr. Angela Heucher
  • Judith Ihl
  • Michèle Kiefer
  • Dr Marcus Kaplan
  • Steffen Schimko
  • Dr Kathrin Wolf

German development cooperation is pursuing the objective of reducing negative social and environmental effects in global (textile) supply chains and thus, in the long term, contributing to designing them more sustainably. This evaluation examines, in particular, the interaction between various development cooperation instruments and measures to promote sustainable global supply chains in the textile sector.
