“…This highlights the humongous and detrimental effects the invasiveness of water hyacinth can have in economically productive water resources, which by extension can negatively impact a nation's agricultural sector. Worku and Sahile [ 99 ] reported the impacts of water hyacinth on Lake Tana in Ethiopia. The lake is said to provide economic benefits to individuals living in its surroundings in the form of fishing and recreational facilities.…”

Water hyacinths pose serious challenges to humanity and the environment. Considering the enormity of the menace associated with the growth and spread of the plant and the difficulty in achieving a single, generally acceptable control method, it is becoming increasingly imperative to explore the potentials of the plant. New water hyacinth-related articles are regularly being published. Recently published articles about the plant were accessed, and the information in these articles is presented in the context of the pros and cons of the plant. Some of the benefits that can be derived from the plant include biogas and biofuel production, medicinal functions, vermicomposting, compost production, and bioremediation. However, clogging of waterways, obstruction of water transportation, and fishing activities; breeding grounds for pests and diseases; and reduction of water quality, loss of biodiversity, and economic downturn in areas invaded by the plant are problems associated with it. The peculiarity in the invasiveness of each situation should determine whether or not the growth of the plant is a problem, especially if the opportunity to harness the potentials of the plant exists. There are three major methods for controlling the plants when control becomes inevitable: mechanical, chemical, and biological. To achieve the best control, integrating two or more control methods is advised.

“…Sediment concentration in rivers over the last 30 years became double indicating more efficient sediment trapping in the floodplain as a result of higher lake levels, rising river beds, and farmers intervening with the course of the river near the shore (Abate et al., 2017). Conservation problem in the Lake Tana Biosphere Reserve world heritage site has increased the infestation since it was known to appear in 2011 not more than 80–100hectare (Tewabe, 2015) has reached to over 20,000 hectares (Tewabe et al., 2017) and to 50,000hectare (Worku and Sahile, 2017).…”

This study has investigated the factors that determine the conservation of one of the major ecosystem in Ethiopia, Lake Tana Biosphere Reserve, using primarily quantitative followed by qualitative approach to provide adequate results of the problem under study. The study has employed the descriptive design and a total of 305 samples from rural households (n = 159) and tourism-related enterprises (n = 146) were selected based on a stratified random sampling technique. Samples were drawn based on their direct attachment either in their livelihood and possess a responsibility to the study area. Data were collected through questionnaires, observation, focus group discussion, unstructured interview and secondary data was consulted. Exploratory factor analysis was used to extract dimensions for environmental awareness. Binary logistic regression was used to analyze data using SPSS version 23. Ten Socio-demographic variables of samples were used as an independent variable and environmental conservation dimensions as dependent variables. The result revealed that out of the 10 variables employed in the analysis, six variables were found significant. Hence, marital status, household size, income source, household income, membership to club and resident location were found to be significant. Qualitative analysis revealed wrong reports for political consumption driven little government attention and lack of integrated natural resource management policy and plan were major factors hindering conservation. A vivid and holistic destination management policy making with enough room to stakeholders' involvement shall be a prior task for the government for better conservation of the ecosystem and sustainable development.

“…La falta de luz en el interior del agua y el descenso del nivel de calado provoca pérdidas de biodiversidad en las cuencas afectadas (EPPO/OEPP, 2008; Téllez et al, 2008;UNEP, 2013). Al mismo tiempo, la infección de los cuerpos de agua provoca problemas en las poblaciones que basan su economía en la agricultura o la pesca vinculada a dichos recursos naturales (Tewabe et al, 2017;Villamagna and Murphy, 2010;Waithaka, 2013;Waithaka et al, 2017;Worku Abera, 2018).

“…La situación se ha cronificado y la plaga sigue presente a pesar de los esfuerzos de control y gestión que lidera el gobierno de Zimbabue junto con expertos de la Universidad de Chiyoni (Mashingaidze, 2013). En los años en los que se desarrolla esta investigación, la proliferación del JA es especialmente agresiva en el lago Tana en Etiopía (Tewabe et al, 2017;Worku Abera, 2018). Las primeras estimaciones hablan de 40.000 ha infectadas, habiéndose producido la infección muy rápidamente (Worku Abera, 2018).…”

“…Para las labores de extracción de la biomasa de los cuerpos de agua infectados, independientemente de si la extracción la realiza la comunidad local o personal contratado por la empresa, los operarios deben recibir una formación previa para asegurar una correcta extracción y manejo de la planta. Estudios anteriores confirman que un incorrecto manejo de la planta por parte de la población local aumentó el área de infección de la plaga (Mashingaidze, 2013;Tewabe et al, 2017;Worku Abera, 2018). Así, los operarios deben tener claro que las plantas deben extraerse enteras, sin dejar trozos en las orillas y áreas cercanas a los cuerpos de agua.…”
