Activity for the first phase of development is well underway and is on track to be completed by the end of 2023. The project has surpassed significant milestones, with over 700 contracts signed to date, worth nearly SAR 19 bn ($5bn). The 100-hectare Landscape Nur...
Globally, peatlands cover an area of 400 million hectare, which is equivalent to 3% of the Earth's land area. These ecosystems store a large fraction of terrestrial carbon, as much as 528 Pg (Pg 1× 1015 g), or one-third of global soil carbon (Murdiyarso., et al 2010). Lowland ...

Other areas along Metro Line 1 had lower population density (i.e., less than 50 persons per hectare; see Fig. 4(a)). In 2017, Metro Line 1 further extended east to the populated areas of Qiantang, bypassing the more densely populated Gongshu, while Metro Line 2 extended northwest ...
Genets ranged in distribution from five to 33 genets per hectare (GPH), with a mean of eight GPH and the average A. gallica genet occupying 0.13 ha. Allele frequencies produced an unbiased expected heterozygosity (HE) value of 0.112 (SE = 0.006) and a Neis expected heterozygosity (HJ) ...
There are many livestock operations within the watershed with an average density of 24 animals per hectare. Poultry represent the majority of livestock operations (97 %) and manure P production (31 %), and swine operations represent 1 % of livestock operations. Populations of dairy and beef ...
Here, we estimate the nutrient removal capability of large-scale Chinese seaweed farms to determine its significance in mitigating eutrophication. We combined estimates of yield and nutrient concentration of Chinese seaweed aquaculture to quantify that one hectare of seaweed aquaculture removes the ...
With no experience of harvesting crops many failed to produce the amounts they were required to grow (3 tonnes of rice per hectare). Most of the workers worked for 19 hour days and many thousands died from starvation and heat exhaustion whilst working in these labour camps. In these labour...

Remaining upland inputs represent a net annual increase in landscape storage in soils or biomass exceeding 10kg per hectare in some areas. Such insights are important for planning watershed restoration and for improving future watershed models.
