Employing a linkage between a biophysical and an economic model, this study estimates the economic impact of soil erosion by water on the world economy. The global biophysical model estimates soil erosion rates, which are converted into land productivity losses and subsequently inserted into a global market simulation model. The headline result is that soil erosion by water is estimated to incur a global annual cost of eight billion US dollars to global GDP.

Payments for Ecosystem Services (PES) are widespread in conservation policy. In PES, environmental effectiveness and social equity are often perceived as conflicting goals. Empirical studies on the relationship between popular design features, such as payment differentiation and payment conditionality, and effectiveness and equity are scarce. Further, they struggle with measuring and separating ecological and equity outcomes.

The transition of farms and ranches to the next generation has generated considerable attention and concern. Over the past 30 years, public and private institutions across the U.S. have introduced policies and programs to help farms without identified family successors achieve successful transfers by connecting them with new farmers through “farm link” services. However, the effectiveness of these services is unclear and assessment is needed.

Cameroon’s current land law appears to have two conflicting objectives: to attract investors through large-scale land concessions while simultaneously protecting biodiversity, defending local people’s rights and promoting rural development. But the legislation governing large-scale land-based investments is outdated and sometimes incoherent. The land allocation process is investor driven and does not appropriately balance economic, social or environmental considerations.

The Bhutan Forest Note articulates opportunities for supporting Bhutan's sustainable development aspirations, including its constitutional commitment to maintain at least 60 percent of the country's land area under forest cover and to better respond or prepare for vulnerabilities such as climate change and natural disasters. The note presents a forward-looking business case for Bhutan to support an increase in forest utilization without jeopardizing the integrity of forest and non-forest ecosystems.

Endemic species on mountains often have narrow altitudinal ranges and are more threatened at the higher altitudes, especially with climate changes. However, plants could use special microhabitats at the mountain tops as proper places for surviving the climate change (i.e., refugia). We assessed population attributes of three critically endangered endemic species (Primula boveana Decne ex Duby, Rosa arabica Crep., and Silene leucophylla Boiss.) in two growing seasons (2006/2007 and 2013/2014), differing in the received rainfalls in microhabitats at the high mountains of southern Sinai.

The proper delineation of site-specific management zones is very important in the agricultural land management of potentially degraded areas. There is a necessity for the development of prospective tools in management plans to correctly understand the land degradation processes. In order to accomplish this, we present a pedo-geomorphological approach using soil texture, land elevation and flow vector aspects to distinguish different management zones and to discretize soil micronutrients. To achieve this goal, we conducted the study in the Neyshabur plain, Northeast Iran.

Viewpoint geological and geomorphological heritage sites (geosites and geomorphosites) offer panoramic views over unique geological features and landscapes dominated by significant features. The environmental context is of crucial importance for these sites. Three components of a viewpoint geosite environment are proposed: standpoint environment, transitional environment, and target environment.

Most current research on land-use intensification addresses its potential to either threaten biodiversity or to boost agricultural production. However, little is known about the simultaneous effects of intensification on biodiversity and yield. To determine the responses of species richness and yield to conventional intensification, we conducted a global meta-analysis synthesizing 115 studies which collected data for both variables at the same locations. We extracted 449 cases that cover a variety of areas used for agricultural (crops, fodder) and silvicultural (wood) production.

On the occasion of the World Environment Day 2019, the Government of Myanmar launched two new policies that will guide Myanmar’s environmental management and climate change strategy.

In Uzbekistan, where agriculture is an important source of income for rural population, land degradation is a major challenge for the environment and the food security. The traditional focus of rainfed agriculture on production of grains with intensive mechanical soil tillage leads to depletion and loss of topsoil. Growing legume crops like chickpeas, can improve the soils.

The objective of this study was to model and analyze the influence Vallerani rainwater
harvesting (RWH) structures have on the soil moisture dynamics in the Jordanian Badia
and to test viability of these structures when influenced by climate change. HYDRUS-2D
was used for the modelling. A three-month fieldwork was performed to set up and
calibrate the model. The results show that most of the soil moisture is located
underneath the furrow of the Vallerani RWH structures. The impact on water availability
