Colorado’s rivers and streams are rising after a year of pandemic quarantine and social distancing, and the anticipation of rafters and kayakers is rising as well. But water resource experts

Can farmers and consultants use unmanned aerial vehicles or drones to help precision-level their fields more efficiently and economically?
The short answer is yes, according to Richard Pickett, owner and chief pilot of P&P Consulting LLC in Jonesboro, Ark. But it comes with some caveats, as Pickett explained during a presentation for this year’s virtual Arkansas Soil and Water Education Conference.
One of those has to do with the slow Internet speeds that farmers often encounter when they try to download information. Another is the sheer volume of data that UAVs can generate when they fly across large acreages.
American Canyon did the water math and found the numbers don t add up without securing additional supplies, not by a long shot.
The equation is simple: the city used 2,884 acre-feet last year and has 1,852-acre feet readily available this year amid a drought. Assuming water use remains the same, that s a 1,032 acre-foot deficit.
To fill the gap, the city will add another 1,040 acre-feet using Vallejo emergency permit water and supplies from state water transfer programs. But that leaves little margin for error and no carry-over supplies for 2022, a city report said.

Livestock management and nomadism are the primary source of livelihood for nearly 300 million people in sub-Saharan Africa. Some 40% of the land area of the continent is composed of arid or semi-arid areas which are not well suited to plant propagation but where livestock keeping is possible. In Ethiopia and Kenya, the share of livestock management of the gross domestic product generated by the agricultural sector is close to 20%. For centuries, nomads have had the capacity to adapt to challenging climate conditions by taking advantage of controlled grazing, but the spread of commercial agriculture, population growth, changes in land ownership and the increased prevalence of extreme weather phenomena brought about by climate change threaten the nomadic way of life and weaken the food safety of households practising livestock management.
