Introduction
My research focuses on econometric analysis and bio-physical modelling of farming systems in developing countries. A main emphasis lies on weather variability and climate change impacts. I am interested in the interface of econometric micro-simulation, bio-physical cropping system models, and data science.

Article
Climate change poses a serious risk to the economic growth of sub-Saharan Africa. Sustainable enhancement of resilience and mitigation capacity of small farm households is a major political economy goal. This paper has the objective to assess the on-farm economic and mitigation benefits of climate-smart agriculture production and their cost-effecti...
Article
The sustainable intensification of agriculture is a widely utilized research and policy concept that has been subject to an extensive body of scientific literature. A key aspect of the concept is its multi-dimensional and cross-disciplinary nature, and the need for cross-disciplinary research methodologies that integrate biophysical and socio-econo...

The agricultural development project, Peru Cacao Alliance (PCA), has contributed to climate change mitigation. Estimated carbon sequestration from perennial crop expansion, which was –211,467 tCO2e metric tonnes of carbon dioxide equivalent per year, more than offset increased greenhouse gas emission (GHG) from fertilizer and pesticide management (...

An analysis of the potential climate change mitigation impact of the project entitled Agricultural Development and Value Chain Enhancement Activity II (ADVANCE II) in Ghana shows that an approximate reduction in greenhouse gas (GHG) emissions of 100% will be possible. When project targets are achieved, ADVANCE II will transform the project area fro...

Analysis of the potential mitigation impacts of the agricultural development project Chanje Lavi Plantè in Haiti indicated that large amounts of carbon sequestration could be achieved through reforestation and perennial crop expansion. The project’s strategy for watershed and landscape restoration links investments in profitable orchard systems wi...
Article
Full-text available
Climate-smart agriculture (CSA) would enhance the capacity of farming systems to sustainably support food security in the context of climatic changes. CSA practices may constitute an ex-ante adaptation strategy while also generating environmental benefits in the form of climate change mitigation. However, questions arise about the profitability of...

Article
Climate-smart agriculture (CSA) aims at enhancing the capacity of farming systems to sustainably support food security in the context of climatic changes (CC). Questions arise about the profitability of alternative farming options and their cost-effectiveness in mitigating CC. A large dataset has been built through household surveys, key informant...
Conference Paper
Full-text available
The quantification of agricultural greenhouse gas (GHG) emissions is an important component of the Climate Smart Agriculture (CSA) agenda, and a key step in managing and ultimately reducing those emissions in a cost-effective manner. The scale and speed of climate change requires considerable investment in filling knowledge gaps and in research, fo...

Promising sustainable land management (SLM) options are available to reverse land degradation. Yet, land degradation and desertification are threatening people’s livelihoods and food security, particularly in the dry areas with unfavourable climate variability and change. We propose a guiding opportunistic approach to reverse this trend. The approa...

The Ex-Ante Carbon-balance Tool (EX-ACT) is an appraisal system developed by FAO providing estimates of the impact of agriculture and forestry development projects, programmes and policies on the carbon-balance. The carbon-balance is defined as the net balance from all greenhouse gases (GHGs) expressed in CO2 equivalent that were emitted or sequestered due to project implementation as compared to a business-as-usual scenario. EX-ACT is a land-based accounting system, estimating C stock changes (i.e. emissions or sinks of CO2) as well as GHG emissions per unit of land, expressed in equivalent tonnes of CO2 per hectare and year. The tool helps project designers to estimate and prioritize project activities with high benefits in economic and climate change mitigation terms. The amount of GHG mitigation may also be used as part of economic analyses as well as for the application for additional project funds. EX-ACT can be applied on a wide range of development projects from all AFOLU sub-sectors, including besides others projects on climate change mitigation, sustainable land management, watershed development, production intensification, food security, livestock, forest management or land use change. Further, it is cost effective, requires a compared small amount of data, and has resources (tables, maps) which can help finding the required information. While EX-ACT is mostly used at project level it may easily be up-scaled to the programme/sector level and can also be used for policy analysis
