nearly triple by 2050. The Sustainable Development Goal 2 aims to end hunger and promote sustainable agriculture to achieve food and nutrition security. There needs to be a shift from high-yield crop production to a more diversified cropping system, including underutilized nutritious crops that will contribute to dietary diversity and achieve daily nutrient goals. But for many regions, there is a lack of financial and human resources to support infrastructure and technology required for proper crop irrigation. Because of this, the impact of droughts, floods, and desertification is greater in terms of both African economic loss and human life loss due to crop failure and starvation. In a study conducted by the World Bank, they found that, on average, individuals who suffer from malnutrition lose 10% of their potential lifetime earnings. They also found that countries lose 2%-3% of their GDP due to undernutrition. Additionally, lack of water causes many Africans to use wastewater for crop growth, causing a large number of people to consume foods that can contain chemicals or disease-causing organisms transferred by the wastewater. Greywater constructed wetlands and modified sand filters are two methods of greywater filtration that have been proposed. These methods allow for greywater to be purified or filtered to remove biological hazards from the water that would not be safe to use in agriculture. Thus, for the extremely high number of African areas suffering from water scarcity issues, investing in development means sustainably withdrawing from clean freshwater sources, ensuring food security by expanding irrigation areas, and effectively managing the effects of climate change. The sustainable development goal report aims at increasing safe wastewater use to contribute to increasing food production and improved nutrition. Productivity and development Poverty is directly related to the accessibility of clean drinking water- without it, the chances of breaking out of the poverty trap are extremely slim. This concept of a "water poverty trap" was developed by economists specifically observing sub-Saharan Africa and refers to a cycle of financial poverty, low agricultural production, and increasing environmental degradation. In this negative feedback loop, this creates a link between the lack of water resources with the lack of financial resources that affect all societal levels including individual, household, and community. Within this poverty trap, people are subjected to low incomes, high fixed costs of water supply facilities, and lack of credit for water investments, which results in a low level of investment
