This paper reports the prevalence of malarial parasites in the human population of District Ziarat and Sanjavi. Out of a total of 3765 blood samples 26.8% were found positive for malarial parasite. The incidence of Plasmodium falciparum was 69.5% and that of P. vivax was 30.2%. The incidence was higher (75.9%) in males. Age wise, the prevalence of the disease was 22.2% in Ziarat and 35.2% in Sa...

China’s new round tenure reform has devolved collective forests to individuals on an egalitarian basis. To balance the equity–efficiency dilemma, forestland transfers are highly advocated by policymakers. However, the forestland rental market is still inactive after the reform. To examine the role of off-farm employment in forestland transfers, a simultaneous Tobit system of equations was emplo...

This study focuses on using an ecosystem approach for forestland classification of the Liukuei Experimental Forest of Taiwan Forestry Research Institute. The content includes the delineation of ecosystem units using DTM, the development of a hierarchical ecosystem classification system using GIS and multivariate statistical analysis, the establishment of a forestland classification decision sup...

This study aims to evaluate the efficiency of the concentration-number (C-N) fractal model for discrimination of soil horizon regarding the depth distribution profile. In this regard, soil parameters such as pH, organic carbon content, calcareous mineral content, electrical conductivity and available phosphorus of Ziarat forestland in Golestan Province, north of Iran, has been investigated. The...

In the Loess Hilly Region of China, the widespread conversion of cropland to forestland and grassland has resulted in great increased in organic carbon (C), nitrogen (N) and phosphorus (P) stocks in the shallow soil layers. However, knowledge regarding changes in C, N, and P in deep soil is still limited. To elucidate the responses of deep soil C, N, and P stocks and stoichiometry in response t...

The carbon mitigation literature has separately considered using forests to store carbon and as a source of bioenergy. In this paper, we look at both options to reach a 2°C mitigation target. This paper combines the global forest model, GTM, with the IAM WITCH model to study the optimal use of forestland to reach an aggressive global mitigation target. The analysis confirms that using both opti...

Fragmentation of forest types is an indicator of biodiversity in the Montreal Process, but the available national data permit assessment of only overall forestland fragmentation, not forest type fragmentation. Here we illustrate how to localize national statistics from the 2003 National Report on Sustainable Forests by combining state vegetation maps with national forestland fragmentation maps....

Based on the comparative advantages of forestland in providing a variety of products and services, it is not arguable that different kinds of forestland should produce different compositions of outputs. To investigate the issue regarding forestland-use specialization or the pursuit of multiple uses on same piece of land, this paper starts by revisiting Vincent and Binkley’s paper ‘Efficient Mul...

The effect of forestland availability under different ownership types on license sales for hunting in nine Southeastern states is empirically evaluated. An equation that represents license sales for hunting is estimated assuming the sale of hunting licenses in a particular county is related to the characteristics of that county as well as the characteristics and license sales for hunting in its...

in the northern region are helping forest owners practice sustainable forestry, whether specific programs are more effective than others at accomplishing this goal, and the characteristics of effective programs. Extending from Maine to Minnesota, the 20 states of the U.S. North differ in terms of forest type and ecological regimes from other regions of the country. The region is home to 43% of ...
