agricultural land conversion (alc) has been introduced as one of the most important factorsaffecting ecosystem. this type of conversion has led to several challenges in agricultural development andhuman life. monitoring alc plays a crucial role when dealing with such challenges. the main objective of thisstudywas to monitor the trend ofalc in theqazvin province located in northwest iran from 19...
Land use/cover change (LUCC), as an important factor in global change, is a topic that has recently received considerable attention in the prospective modeling domain. There are many approaches and software packages for modeling LUCC, many of them are empirical approaches based on past LUCC such as CLUE-S, DINAMICA EGO, CA_MARKOV and Land Change Modeler (both available in IDRISI). This study re...
Executive Summary Increasing global demand for food and the need to address climate change risk make it ever more urgent to both protect ecosystems and use land more productively and efficiently. Brazil is a key player in this context and has made significant gains in recent decades. Between 1970 and 2006, its average national cattle farm productivity doubled and its average national crop farm ...
Effective management decisions regarding greenhouse gas (GHG) emissions may be hampered by the lack of scientific tools for modeling future land use change. This study addresses methodological principles development scenario assumed in processes GHG accounting and management. Associated policy implications Lithuania are also discussed. Data on uses, available from National Forest Inventory (NFI...
Green walls and green dams are increasingly being considered as part of many national international desertification initiatives. This paper studies the spatiotemporal evolution dam in Moudjbara region (Djelfa Province, Algeria), from 1972 to 2019, by using Landsat imagery, Land Change Modeler, OpenLand package. The future pine plantations, for year 2029, was also forecasted, based on an anthrop...
The extension of urban perimeter markedly cuts available productive land. Hence, studies in urban sprawl analysis and modeling play an important role to ensure sustainable urban development. The urbanization pattern of the Greater Asmara Area (GAA), the capital of Eritrea, was studied. Satellite images and geospatial tools were employed to analyze the spatiotemporal urban landuse changes. Objec...
The crowned sifaka (Propithecus coronatus) and Decken’s sifaka (Propithecus deckenii) are Endangered lemurs endemic to west and central Madagascar. Both have suffered habitat loss and fragmentation throughout their ranges. The goal of this study, conducted in the Mahavavy-Kinkony Wetland Complex (MKWC) in northwestern Madagascar, was to assess the effects of historical change in the species’ ha...
مدل سازی رابطه تغییرات زمانی و مکانی کربن آلی خاک با کاربری و پوشش اراضی پس از 4 دهه در منطقه دیلمان
تغییرات پوشش/کاربری اراضی و تخریب جنگل و خاک به طور موثر بر انتشار گازهای گلخانه ای اثر می گذارد و منجر به گرمایش جهانی می شود. این تحقیق با هدف مدل سازی مکانی روابط بین تراکم کربن آلی خاک (socd) و مولفه های محیطی و همچنین بررسی نقش تغییرات کاربری اراضی در تغییرات زمانی ذخیره کربن آلی خاک در دو عمق 20-0 و 40-20 سانتی متری بر مبنای سه سناریوی مدیریتی در منطقه دیلمانٍ استان گیلان انجام گرفت. مولفه...
Environmental niche modeling outputs a biological species' potential distribution. Further work is needed to arrive at a species' realized distribution. The Biological Species Approximate Realized Niche (BioSARN) application provides the ecological modeler with a toolset to refine Environmental niche models (ENMs). These tools include soil and land class filtering, niche area quantification and...
Java’s Brantas River Basin (BRB) is an increasingly urbanized tropical watershed with significant economic and ecological importance; yet knowledge of its land-use changes dynamics drivers as well their importance have barely been explored. This the case for many other watersheds in Java, Indonesia beyond. study BRB (1) quantifies period 1995–2015, (2) determines patterns during (3) identifies ...
