However, limited agricultural activity was allowed in the Civilian Control Zone (CCZ) surrounding the DMZ. In this study, land cover and vegetation changes in the western DMZ and CCZ from 1919 to 2017 were investigated. Coniferous forests were nearly completely destroyed during the war and were then converted to deciduous forests by ecological succession. Plains in the DMZ and CCZ areas showed different patterns of land cover changes. In the DMZ, pre-war rice paddies were gradually transformed into grasslands. These grasslands have not returned to forest, and this may be explained by wildfires set for military purposes or hydrological fluctuations in floodplains. Grasslands near the floodplains in the DMZ are highly valued for conservation as a rare land type. Most grasslands in the CCZ were converted back to rice paddies, consistent with their previous use. After the 1990s, ginseng cultivation in the CCZ increased. In addition, the landscape changes in the Korean DMZ and CCZ were affected by political circumstances between South and North Citation: Kim, J.H.; Park, S.; Kim, Korea. -
Between Here and There: Buffer Zones in International Law Eian Katz†
Between Here and There: Buffer Zones in International Law Eian Katz† INTRODUCTION On a December morning in 2015, H.A. left early from his home in central Gaza to tend to his fields of wheat, barley, peas, and fava beans a couple hundred meters from the Israeli border fence. He arrived to find a low-flying Israeli aircraft spewing a thick, white substance over his farmland as it traveled south along the Palestinian side of the divide. Two days later, H.A. observed signs of damage to the leaves of his plants. Within ten days, his entire crop had shriveled and died, leaving him without his only source of income and unable to repay a loan for agricul- tural inputs.1 Like many Palestinians, a substantial portion of H.A.’s lands lies within the Israeli-imposed “no-go zone” inside the Gaza Strip, which in recent years has also been converted into a “no-grow zone” for farmers.2 Facing threats of rocket attacks, improvised explosive devices (IEDs), and border infiltration, Israel sprays herbicides throughout this area in order to preserve a clear line of sight.3 Access to certain areas is restricted entirely, with Israel regularly firing on encroaching Palestinians, civilians and mili- tants alike.4 The Israel Defense Forces (IDF) have issued contra- dictory pronouncements as to the precise boundaries and rules of † BA 2013, Yale University; JD Candidate 2018, The University of Chicago Law School. 1 Israel Sprays Gazan Farmland Close to Border Fence, Destroying Crops and Caus- ing Heavy Losses (B’Tselem, Feb 4, 2016), archived at http://perma.cc/56FA-2NGZ. -

Gustav Meibauer is a Ph.D. candidate at the London School of Economics and Political Science. Abstract: Buffer zones as a concept have a long history. Despite their frequent occurrence in international relations past and present, however, they have been treated in passing by scholars and policymakers alike, and then usually from a purely historical perspective. Their importance in conflict management, third-party intervention and power politics are not adequately mirrored in scholarly research. This article seeks to remedy this lapse by re-introducing the buffer zone as a tool of international conflict management in a new and systematic fashion. -
The Massachusetts Vegetated Buffer Manual
TThhee MMaassssaacchhuusseettttss BBuuffffeerr MMaannuuaall Using Vegetated Buffers to Protect our Lakes and Rivers Prepared by the Berkshire Regional Planning Commission For The Massachusetts Department of Environmental Protection 2003 Massachusetts Vegetated Buffer Manual About The Massachusetts Buffer Manual In 2001 the Berkshire Regional Planning Commission was awarded a Nonpoint Source Pollution grant to conduct a demonstration and outreach project. The goal of this project was to promote the bene- fits of vegetated buffers. The three main objectives to achieve this goal were to 1) create a buffer guidance document, 2) plant five buffer demonstration sites and 3) talk about vegetated buffers to the public. This document, three of the buffers seen in Chapter 2 and several presentations made to lake groups and conservation commissioners are direct outcomes of this project. Russ Cohen of the Riverways Program was our partner and co-presenter for three of our "on the road" presentations. Many thanks, Russ. Acknowledgements To our Partners: A very special thank you goes out to our project partners, without whose contributions the Buffer Project would not have been made possible. These plant specialists, landscape professionals and nurseries have voluntarily contributed their time, expertise and materials to our demonstration projects and to this document.

TO RATE OR COMMENT ON THIS PUBLICATION, CLICK HERE 1. Introduction While there is a limited amount of reliable data on Afghanistan‟s economy over the course of the past century, the country‟s economic history has often been closely related to its political history.2 Landlocked yet situated at the crossroads of Asia, Afghanistan could serve as a trade crossroads and a major supplier of natural resources for the global economy. However, in recent decades, the nation‟s vast economic potential has failed to take root. Afghanistan relies on external financial flows from the international community as well as from international terrorist and narcotics-trafficking networks, which, as the UK Department for International Development (DFID) noted in a 2008 report, „are critical for both state building and for opposition/insurgency‟ respectively. Local economic developments have fed into national and regional economic processes which, conversely, have influenced Afghan politics and economics at even the lowest levels. The rapidly-changing nature of these processes has led to a profoundly unstable and volatile “political economy” (that is, the two-way interaction between politics and economics). This report looks closely at developments within the Afghan economy, beginning with an examination of the early Cold War years and then portraying economic trends during the Soviet period and amidst the subsequent internal strife of the 1990s. -
Buffer Zones Around Protected Areas: a Brief Literature Review
UCLA Electronic Green Journal Title Buffer Zones Around Protected Areas: A Brief Literature Review Permalink https://escholarship.org/uc/item/02n4v17n Journal Electronic Green Journal, 1(15) Author Martino, Diego Publication Date 2001-12-01 Peer reviewed eScholarship.org Powered by the California Digital Library University of California Buffer Zones Around Protected Areas: A Brief Literature Review Diego Martino Department of Geography & Environmental Studies, Carleton University, Canada ..................................... This literature review is based on 53 articles (26 from peer-reviewed journals). Forty-two of these articles specifically refer to the type of buffer zones analyzed here. The main goals set for this review are to identify the principal issues around the buffer zone concept at the present date and to determine the main problems and advantages of the concept. It is clear from the review that there is no agreement among conservationists regarding what is, or should be, the role of buffer zones. Due to this, confusion arises on what the objectives of buffer zones are. Two antagonist positions are identified. One proposes buffer zones as an extension of national parks and the other argues for buffer zones whose major role is to integrate parks and people. I conclude that regardless of the position taken there is an urgent need for a clear definition on the objective of buffer zones. The importance of a literature review on buffer zones is highlighted in a recent article by Prins and Wind (1993) which indicates that buffer zones, and the effective use of them, is one of the major priorities in the conservationists' and wildlife managers' agenda (p. -
Redrawing the 151-Mile Border Between North and South Korea
The Demilitarized Zone: Redrawing the 151-Mile Border Between North and South Korea THE DEMILITARIZED ZONE The demilitarized zone between North and South Korea is “one of the most closed and tightly controlled borders of the world” (Wastl-Walter, 4). The Korean Demilitarized Zone (DMZ) is a 4-km-wide (2.5 mile), 250-km-long (151 mile) military buffer zone between North and South Korea. The DMZ is the first main case study of my larger ongoing research titled “border as urbanism.” The current form Dongsei Kim of the demilitarized zone was established after the Korean War Armistice Columbia University was signed between the United Nations and North Korea with China, some 60 years ago on July 27, 1953.1 WHY IS THE DMZ AS A CASE STUDY? The primary justification of the DMZ being the central case study in explor- ing the notion of “border as urbanism” is that it is one of the most extreme cases of a tightly closed and controlled border. In addition, it is one of the most heavily militarized borders in the world, one that withstood the fall of Communism and the end of the Cold War (Gelézeau, 325, 327). Despite this extreme impermeability, the DMZ’s inherent flows, processes, and reciproc- ities, over time clearly prove that borders are never static or fully closed. Furthermore, because of this extreme condition, the DMZ becomes the best illustration of comprehending the inherent porosities and malleability of borders. The second rationale of the DMZ as a case study is related to it being a rep- resentation of a conflict that is common among many nation-state border territories. -

Rubin and Abubakar Siddique The United States Institute of Peace has been working on the stabilization and reconstruction of Afghanistan since 2002. Institute initiatives focus on security, the rule of law, conflict resolution, building civil society, and education in Afghanistan and Afghanistan’s relations with its neighbors. The Institute’s Afghanistan Working Group, chaired by Dr. Barnett R. Rubin, is composed of government officials Resolving the Pakistan- and nongovernmental organizations that discuss critical issues facing Afghanistan with top experts and policymakers and work directly to help the Afghan people build a peaceful and prosperous society. Afghanistan Stalemate The idea for this report started with discussions by Barnett Rubin with delegates to the Afghan constitutional Loya Jirga, President Hamid Karzai, and journalist Ahmed Rashid in December 2003. In spring and summer 2004 Abubakar Siddique conducted field work on the current positions of the diverse stakeholders in this complex region. During subsequent trips the coauthors carried out additional research, most recently in July–August 2006, when Rubin visited Afghanistan and Siddique visited Pakistan. Grants from the Rockefeller Foundation, the Open Society Institute, the Royal Government of Norway, and the Government of the United Kingdom supported the research. The authors gratefully acknowledge the assistance of Afrasiab Khattak and Ahmed Rashid in Pakistan and Omar Zakhilwal, Rasul Amin, Hamed Wardak, and Humayun Hamidzada in Afghanistan. They also thank many anonymous informants and commentators from Pakistan, Afghanistan, and the United States. -
The International Politics of State Building
The international politics of state building James D. Fearon Stanford University May 1, 2020 1 No man is an island, and neither are most fragile states • State building projects in fragile states do not occur, and should not be imagined to occur, as if they were purely a matter of reforms within domestic politics and society, assisted and properly incentivized by well-intentioned aid donors and, sometimes, peacekeeping forces. • But this is how we (theorists and practitioners of the western major powers’ donor, military intervention, and peacekeeping forces) talk about the problem. • This was fictional even during the post-Cold War phase. See for example UN Security Coun- cil logrolls that allowed peacekeeping operations in Haiti and Georgia (Fearon and Laitin, 2004, 14). But it was close enough to reality for some of the paradigmatic cases of the 1990s that the international political constraints on state building in fragile states could be elided with euphemisms (such as “the international community”). • The international conditions of the emerging post-post-Cold War period make it clearer that state-building in fragile states is almost always a problem of international politics. • If that is right, then we should focus more on what can be done at the level of relations and agreements among major powers and regional powers concerning “meddling” in fragile states. • The instruments for state building – in some cases, the first necessary steps – include clas- sical diplomatic tools such as spheres of influence, buffer states, detente´ with ideological adversaries, and mediation to facilitate strong-state bargains. 1 2 Some examples 1. -
