Forest cover is an important input variable for assessing changes to carbon stocks, climate and hydrological systems, biodiversity richness, and other sustainability science disciplines. Despite incremental improvements in our ability to quantify rates of forest clearing, there is still no definitive understanding on global trends. Without timely and accurate forest monitoring methods, policy r...

In a world reached a population of six billion humans increasingly demand it for food, feed with a water shortage and the decline of agricultural land and the deterioration of the climate needs 1.5 billion hectares of agricultural land and in case of failure to combat pests needs about 4 billion hectares. Weeds represent 34% of the whole pests while insects, diseases and the deterioration of ag...

The island of Tenerife covers 203,000 hectares and has a resident population of 685,582. Approximately 12,500 hunting licenses are issued each year. There are 158,351 hectares currently available for hunting once security zones and protected areas have been excluded, resulting in a theoretical density of nearly 13 hectares per hunter. This excessive pressure has an impact on the following speci...

The objectives of the research were (1) to analyze value biocapacity and ecological footprint in Sleman Regency; (2) measure spatial distribution bioecological carrying capacity global hectare units (global hectare); (3) formulating direction development control based on class capacity. was conducted using a quantitative approach through processing analyzing secondary data from various sources....

We offer a nationwide analysis of the initial years of Costa Rica’s PSA program, which pioneered environmental-services payments and inspired similar initiatives. Our estimates of this program’s impact on deforestation, between 1997 and 2000, range from zero to one-fifth of 1% per year (i.e., deforestation is avoided on, at most, 2 out of every 1,000 enrolled hectares). The main explanation for...

The first is the burning of large tracts of forests in Indonesia (in Sumatra and Kalimantan, the Indonesian part of Borneo). Estimates of the total area of forest damaged by the fires vary from the official figure of 750,000 hectares to the figure of 1.7 million hectares made by the Indonesian environmental group WALHI.1 The forest fires, which have been going on for months, have created an eno...

This review studies biofuel expansion in terms of competition between conventional and advanced biofuels based on bioenergy potential. Production of advanced biofuels is generally more expensive than current biofuels because products are not yet cost competitive. What is overlooked in the discussion about biofuel is the contribution the industry makes to the global animal feed supply and land u...

Irrigation accounts for 70% of global water use by humans and 33–40% of global food production comes from irrigated croplands. Accurate and timely information related to global irrigation is therefore needed to manage increasingly scarce water resources and to improve food security in the face of yield gaps, climate change and extreme events such as droughts, floods, and heat waves. Unfortunate...


 Growing concern about climate change created the need for a globally applied system of accounting to track demand on earth’s resources and their supply. An ecological footprint analysis provides an objective metric impact nation has environment, measured in global hectares/capita. Using data provided by Global Network, we calculate that UAE deficit 9.2 hectares/person but only 9% area re...
