Climate is subject to.fluctuatio.s in the majo.ity o. the wo.ld, mainly caused by rainfall as well as temperature variatio.s. Climate fluctuatio.s in Kenya have resulted in the spread o. desert-like co.ditio.s in the ASALs regio., such as Marigat in Baringo.Co.nty. As a co.nty, Baringo.experiences great variatio.s in climate annually, as well as uncertainty in expected rains, thereby negatively impacting the pro.uctio. o. cro.s such as so.ghum. This study applied the rainfall ano.aly index (RAI), standardised precipitatio. evapo.ranspiratio. index (SPEI), standard precipitatio. index (SPI), and Mann-Kendall (MK) statistical test fo. trends o. histo.ical climatic data in analysing bo.h temperature and precipitatio. data o.er the perio. 1990 to.2022 to.determine their trend, patterns and ho. they affect the pro.uctio. o. so.ghum cro.s. The machine learning metho. (R studio. with inputs was used to.calculate the SPI, SPEI, RAI and MK trend test. The rainfall varied fro. belo. average to.abo.e average during the study perio. with no.clear pattern in the RAI, SPEI and SPI values. The years 2020 and 2000 sto.d o.t as they had higher and lo.er rainfall than usual, respectively. The Marigat area generally experienced mo.e rainfall during the high/lo.g rainfall seaso. (AMJJ). The MK trend test o. average mo.thly rainfall, So.D, AMJJ, and annual precipitatio. co.firmed a po.itive trend in precipitatio.. Ho.ever, the sho.t rainy seaso. (So.D) was fo.nd to.be the mo.t variable perio. fo. rainfall, and there was a slight increase in daily average temperatures during this seaso..

Glypho.ate-based herbicides are widely used aro.nd the wo.ld, making it likely that mo.t humans have significant expo.ure. Because o. habitual expo.ure, there are co.cerns abo.t to.icity including neuro.o.icity that co.ld result in neuro.o.ical, psychiatric, o. co.nitive impairment. We recently fo.nd that a single injectio. o. glypho.ate inhibits lo.g-term po.entiatio., a cellular mo.el o. learning and memo.y, in rat hippo.ampal slices dissected 1 day after injectio., indicating that glypho.ate-based herbicides can alter co.nitive functio.. Glypho.ate-based herbicides co.ld adversely affect co.nitive functio. either indirectly and/o. directly. Indirectly, glypho.ate co.ld affect gut micro.io.a, and if dysbio.is results in endo.o.emia(leaky gut), infiltrated bacterial by-pro.ucts such as lipo.o.ysaccharides co.ld activate pro.inflammato.y cascades. Glypho.ate can also.directly trigger pro.inflammato.y cascades. Indeed, we o.served that acute glypho.ate expo.ure inhibits lo.g-term po.entiatio. in rat hippo.ampal slices. Interestingly, direct inhibitio. o. lo.g-term po.entiatio. by glypho.ate appears to.be similar to.that o. lipo.o.ysaccharides. There are several po.sible measures to.co.tro. dysbio.is and neuro.nflammatio. caused by glypho.ate. Dietary intake o. po.ypheno.s, such as quercetin, which o.erco.e the inhibito.y effect o. glypho.ate o. lo.g-term po.entiatio., co.ld be o.e effective strategy. The aim o. this narrative review is to.discuss po.sible mechanisms underlying neuro.o.icity fo.lo.ing glypho.ate expo.ure as a means to.identify po.ential treatments.
