The Bar Chart Showing Percentage Share of Five Different Industries' Brazil's Economy in 2009 and 2019 with a Forecast for 2029 IELTS Writing Task 1

Turning to the estimated estimates for 2029, only the Finance sector is expected to rise by 5% again in 2029. Tourism remains at roughly 21% of the remaining sectors, while Food Processing and Oil, Coal, and Gas return to 2009 levels (11 and 26%, respectively). Meanwhile, Manufacturing's share continues to decline, decreasing by another 10% to roughly 5%.

Overall, over the time period covered, the Finance sector stands out as having the largest share of the Brazilian economy, and its share continues to expand. Manufacturing is the largest loser, starting as the equal smallest industry and seeing both real and anticipated declines.

Conversely, the manufacturing industry's share steadily diminished from a little over 20% in 2009 to slightly more than 15% in 2019; experts predict this decline will persist: by the year 2029, they anticipate that only about 5% of our economy will be attributed to manufacturing. Thus--this projection signals significant challenges on the horizon for the manufacturing sector.

From a 10% surge in 2009 to just over 20% by 2019, the food processing sector witnessed significant growth. Yet predictions anticipate an impending reversal of this trend; it is likely that the industry's share will shrink back down to only being at approximately 10% by the year-end of 2029. In comparison, tourism and oil- coal- and gas industries boasted shares exceeding more than quarter (25%) each during those years: however—by contrast with these other sectors' stability over time—tourism saw its percentage decrease from one-fifth(20%)in two consecutive decades(2009 ,2019). Further analysis projects a consistent future for tourism at this reduced level(20%), while forecasting a return-to-normality trajectory for oil-coal-gas industry—it’s expected they would revert back their original share come–2020s end date!

The finance industry escalated from a base of over 30% in 2009 to surpass 35% by 2019, and projections suggest further growth up to approximately 40% by the end of the following decade; thus positioning it as Brazil's leading economic contributor among its five provided sectors. Tourism, oil - along with coal and gas shares- all stood above a quarter mark at around or exceeding one-fourth worthiness during that initial year. Nonetheless: tourism plummeted sharply down towards an estimate of merely twenty percent coming close to '19 – this trend is predicted to persist into future years such as '29'. Meanwhile—oil, coal moreover gas—are expected not only continue their significant surge they recently experienced vaulting them upwards significantly past thirty percent but also return back toward previous levels by two thousand twenty-nine period itself again becoming major contributors within Brazilian contextual economy alongside Finance sector which maintains its dominance throughout this timeframe.

Predictions indicate a projected plummet in the manufacturing industry's percentage share to roughly 5% by 2029. Despite experiencing an almost 10-point surge—rising from a baseline of 10% to just over 20%--in the food processing sector during 2019; experts anticipate this rate will regress back down to its original position, returning it again at about only ten percent by the year end of twenty twenty-nine.
