Diana Escobar Jaramillo, Agricultural, Food and Environmental Policy Analysis - Master´s Programme


Sustainability assessments that evaluate economic, social and environmental aspects have increasingly become a necessity to support the use of agricultural innovations. Food insecurity and poverty are a major concern for farmers of Tanzania and the technologies rainwater harvesting and fertilizer micro-dosing promise to aid in easing these burdens. I perform an ex-post sustainability analysis at the household and farm level to evaluate the effect of these innovations in two contrasting regions, semi-arid Dodoma and semi-humid Morogoro. I account for households’ and farms’ characteristics, estimate sustainability indicators, and apply a differences-in-differences propensity score matching estimator. The results indicate that the biophysical and socio-economic characteristics of the place where rainwater harvesting and fertilizer micro-dosing are applied determines their success. Contrary to the expectations, the semi-arid region of Dodoma does not prove to benefit from the adoption of the innovations, neither in food security nor in economic sustainability, but conflicts in the water used are exacerbated. While in the semi-humid region of Morogoro the innovations further promote environmental sustainability and food security.

Diana Escobar Jaramillo

Quantitative analysis has always been of my interest, and my bachelor’s studies in Economics gave me the opportunity to gain invaluable skills and knowledge; Furthermore, I developed my passion for Agricultural, Environmental and Development Economics when I recognized the role I could play in supporting people from my country, Ecuador, to improve their quality of life and the agricultural sector. The double degree master’s programme AFEPA has widened my knowledge and experience in an intercultural environment, and I expect to make a difference worldwide guiding people to development and wealth by their own efforts, while making this sustainable. I look forward to working in an institution that makes an impact in people’s development and sustainable agriculture, as it also challenges me to expand my potential. From my side I will bring excellence due to my dedication to these goals, my expertise in economic and data analysis tools and my abilities and knowledge about the agricultural, food and environmental field.
