Improving children’s environmental health in Metro Manila, Philippines, through a school water, sanitation, and hygiene intervention
Sangalang, Stephanie Ocampo (2023-02-15)Millions of children are exposed to inadequate water, sanitation, and hygiene (WaSH) in schools globally. Diarrhoea is a leading cause of disease, while dehydration impairs cognitive performance and malnutrition hinders ... -
Improving crop varieties of spring barley for drought and heat tolerance with AB-QTL-analysis
Mohammed, Khalaf Ali Hamam (2004)In the years 2002-2003, 323 BC<sub>2</sub>DH individuals of double haploid (DH) spring barley population were genotyped with SSRs markers. The BC<sub>2</sub>DH lines were evaluated in greenhouse trials for drought and heat ... -
Improving Employment Prospects for Africa’s Rural Youth: Harnessing the potential of the agriculture sector for long-term job creation
Baraké, Evelyn; von Braun, Joachim; Kofol, Chiara (2017-11)Rural youth are an important yet underutilised resource for agricultural growth and economic development in Sub-Saharan Africa (SSA). In rural areas, the prevalence of vulnerable, low-quality jobs constitutes the main ... -
Improving energy access in rural areas: How to incentivize the transition to modern energy solutions in rural India
Gaur, Varun; Haluska, Nicholas (2019-06)Access to energy remains a critical issue around the globe. At least 1.3 billion people worldwide do not have adequate access to electricity. Due to the unreliability of the electricity supply, power outages are frequent ... -
Improving milk value chains through solar milk cooling
Salvatierra Rojas, Ana; Torres Toledo, Victor; Mrabet, Farah; Müller, Joachim (2018-09)Smallholder dairy farms are the major providers of marketed milk in Kenya, producing one to ten liters per day. Due to this low production level, farmers are usually associated in cooperatives. Dairy cooperatives are ... -
Improving nitrogen retention in soils treated with Pig and cattle slurry through the use of organic soil amendments
Cao, Xinyue (2023-06-21)Animal slurry has recently experienced a renaissance as organic nitrogen (N) fertilizer because, on the one hand, sustainable organic farming is receiving growing attention in order to protect the environment and, on the ... -
