Effect of birth date on growth performance of calves of seasonally-bred range cattle por Rege, J.E.O., Moyo, Siboniso

“…This was attributed to a positive residual effect of maternal environment arising from the fact that calves born late were those whose dams had a substantial proportion of the critical last trimester of the gestation period in a favourable season. …”

Projections and impact assessment of the local climate change conditions of the Black Volta Basin of Ghana based on the Statistical DownScaling Model por Siabi, E. K., Phuong, D. N. D., Kabobah, A. T., Akpoti, Komlavi, Anornu, G., Incoom, A. B. M., Nyantakyi, E. K., Yeboah, K. A., Siabi, S. E., Vuu, C., Domfeh, M. K., Mortey, E. M., Wemegah, C. S., Kudjoe, F., Opoku, P. D., Asare, A., Mensah, S. K., Donkor, P., Opoku, E. K., Ouattara, Z. A., Obeng-Ahenkora, N. K., Adusu, D., Quansah, A.

“…As such, climate actions to combat detrimental effects on the BVB must be revamped since the basin hosts one of the largest hydropower dams in Ghana. The study is expected to support the integration of CC mitigation into local, national, and international policies, and support knowledge and capacity building to meet CC challenges.…”

Identification of suitable land for supplemental surface irrigation in semi-arid areas of North-western Ethiopia por Adem, Anwar A, Yibeltal, Mesenbet, Mhiret, Demisew A, Tilahun, Seifu A, Zimale, Fasikaw A, Abeyou, Abeyou, Enku, Temesgen, Teferi, Ermias T.

“…The effective rainfall of the wet months (June, July and August) is sufficient to supplement the rainfed crop in the late growing season. Earthen dams are recommended as water harvesting structures to practice supplemental irrigation in large suitable areas. …”

Evaluation design for the environmental and natural resource management project in Malawi por Coen, Thomas, Mamun, Arif, Ringler, Claudia, Nkonya, Ephraim M., Velyvis, Kristen, Xie, Hua, Powell, Helen, Brecher-Haimson, Jeremy, Dumitrescu, Anca, Sloan, Matt

“…Mechanical removal of weeds and dredging of sediment around dams and in head ponds should dramatically improve water flow in the short term, but longer term solutions likely entail engaging upstream communities in improved agricultural and environmental practices that focus on preventing environmental degradation, soil erosion, and fertilizer runoff (United Nations Environment Programme 2013). …”

Introduction [in Advancing the climate and bioeconomy agenda in Africa for resilient and sustainable agrifood systems] por Yamdjeu, Augustin Wambo, Glatzel, Katrin, Tadesse, Getaw, Savadogo, Moumini

“…In one of the latest illustrations of climate change impacts across Africa, several thousand people lost their lives in Libya after torrential rain caused two dams to collapse in September 2023. The recent El Niño–induced droughts and floods across Southern Africa have led the United Nations and its partners to call for urgent action, as more than 30 million people across the region face the effects of severe drought. …”

Understanding barotrauma in fish passing hydro structures: a global strategy for sustainable development of water resources por Brown, Richard S., Colotelo, Alison H., Pflugrath, Brett D., Boys, Craig A, Baumgartner, Lee J., Deng, Zhiqun Daniel, Silva, Luiz G.M., Brauner, Colin J., Mallen-Cooper, Martin, Oudom Phonekhampeng, Thorncraft, Garry, Douangkham Singhanouvong

“…One activity associated with declines in freshwater fish populations is water resource development, including dams, weirs, and hydropower facilities. Fish passing through irrigation and hydro infrastructures during downstream migration experience a rapid decrease in pressure, which can lead to injuries (barotrauma) that contribute to mortality. …”

Plant-based vaccine candidate against Infectious bursal disease: an alternative to inactivated vaccines for breeder hens por Lucero, Maria Soledad, Richetta, Matias Daniel, Chimeno Zoth, Silvina Andrea, Jaton, Juan, Pinto, Silvina, Canet, Zulma Edith, Berinstein, Analia, Gomez, Evangelina Raquel

“…Strict hygiene management together with effective vaccination programs are the most important strategies to prevent Infectious bursal disease virus entry in poultry production facilities. Hyperimmunisation of dams with inactivated vaccines just before the laying period provides passive immunity to the progeny that protects them during the critical first few weeks after hatching before vaccination with live attenuated virus takes place. …”

Efficacy of the spray-drying treatment to inactivate the bovine leukemia virus in bovine colostrum por Lomonaco, Marina, Sowul, Mariana, Gutierrez, Gerónimo, Malacari, Darío Amilcar, Alvarez, Irene, Porta, Natalia Gabriela, Zabal, Osvaldo Alfredo, Trono, Karina Gabriela

“…The relationship between virus or provirus and specific antibodies in these secretions is particular to each infected cow and will probably determine whether the consumption of colostrum or milk from these naturally infected dams provides an infective or a protective effect in recipient calves. …”

Choosing the proper spatial and temporal resolution for water management: Don’t forget the ‘Invisible’ factors por Vosti, S.A., Torres, M.

“…In the search for the proper spatial and temporal resolution at which to manage natural resources, we are generally guided by the flows and stocks of water that we can ‘see’ – rainfall, flowing water, reservoirs, dams, etc. We use what we observe to identify the socially optimal flows/stocks of water, and then suggest the public policy action required to achieve these results. …”

Do river deltas in east India retreat? A case of the Krishna Delta por Gamage, M.S.D.Nilantha, Smakhtin, Vladimir U.

“…The construction of multiple dams and barrages in many Indian River basins over the last few decades significantly reduced river flow to the sea and affected the sediment regime. …”
