Adaptation to climate change and desertification: Perspectives from national policy and autonomous practice in Malawi

Diciembre, 2009
Malawi
África subsahariana

This paper explores the ways in which the interlinked challenges of climate change and desertification are managed in Malawi. The authors examine the synergy and conflict between local autonomous adaptation strategies and national adaptation policies, which are in accordance with international commitments to the United Nations Convention to Combat Desertification (UNCCD), and the United Nations Framework Convention on Climate Change (UNFCCC).

Shaping forest safety nets with markets: Adaptation to climate change under changing roles of tropical forests in Congo Basin

Diciembre, 2009
República Democrática del Congo
África subsahariana

This paper explores the role of markets for Non-Timber Forest Products (NTFPs) in facilitating climate change adaptation of local communities in the Congo Basin. While forests are regarded as safety nets in the climate change movement, emerging market systems that facilitate a shift to a more cash-based economy may reduce this traditional function. This paper contends that the size of trade in timber and non-timber forest products, overexploitation, and unsustainable practices threaten the integrity of forest ecosystems and the goods and services they provide.

Biocharred pathways to sustainability? Triple wins, livelihoods and the politics of technological promise

Diciembre, 2009

Considerable hype and debate are currently surrounding the potential of biochar (charcoal created through the burning of biomass in low oxygen environments) in climate change mitigation and agriculture. This report attempts to summarise the arguments, assumptions and interests in the biochar debate and offer reflections on its prospects. The report begins by outlining what it calls the triple-win of biochar. The production of biochar can be tuned to release bioenergy or biofuels in the form of syngas and bio-oil, thus providing decarbonised biomass fuel.

Governing and implementing REDD+

Diciembre, 2009

Reducing emissions from deforestation and forest degradation, conserving and enhancing forest carbon stocks, and sustainably managing forests (REDD+) are emerging as a central policy instrument to halt land-use related emissions from developing countries.

REDD-Net COP 15 Briefing

South-Eastern Asia

Thousands came together in "Hopenhagen" from 7-18 December 2009 for what was the most covered and talked about of any United Nations Framework Convention on Climate Change (UNF CCC) Conference of the Parties (COP) to date. Reducing emissions from deforestation and forest degradation in developing countries (REDD-plus)1 was one of few issues on which progress was made. However, implications of the wider negotiations for REDD-plus are not yet clear.

Land use conflicts in the Inner Niger Delta of Mali: does climate change play a role?

Does climate change drive conflict over land use in Mali?

This study investigates the alleged relationship between climate change and conflicts, using the Inland Delta of the Niger River in Mali as a case study, where this region is an African hotspot area in terms of land use conflicts.

The author emphasises that, despite the clear climate developments in the region throughout the last century, researchers are much less sure about future changes. Moreover, the paper finds that:

Agriculture and climate change: Direct and indirect mitigation through tree and soil management

Peer-reviewed publication
Diciembre, 2009

Many opportunities exist for mitigating greenhouse gas (GHG) emissions through better management of trees and soils. There is potential for both direct mitigation through better management of carbon in agricultural landscapes and indirect mitigation through reduced pressure on carbon stored in forests, peatlands, and wetlands. Effectively harnessing these opportunities will take bold action in climate change negotiations.

Agriculture and climate change: An agenda for negotiation in Copenhagen

Peer-reviewed publication
Diciembre, 2009
Europa

Agriculture and climate change are inextricably linked. Agriculture is part of the climate change problem, contributing about 13.5 percent of annual greenhouse gas (GHG) emissions (with forestry contributing an additional 19 percent), compared with 13.1 percent from transportation. Agriculture is, however, also part of the solution, offering promising opportunities for mitigating GHG emissions through carbon sequestration, soil and land use management, and biomass production.

use of historical range and variability (HRV) in landscape management

Journal Articles & Books
Diciembre, 2009

This paper examines the past, present, and future use of the concept of historical range and variability (HRV) in land management. The history, central concepts, benefits, and limitations of HRV are presented along with a discussion on the value of HRV in a changing world with rapid climate warming, exotic species invasions, and increased land development. This paper is meant as a reference on the strengths and limitations of applying HRV in land management.

Az egyre növekvő energiafelhasználás, világnépesség és éhezés olyan, több évtizede megoldatlan problémák, amelyeket a klímaváltozás és az ez által kialakult szélsőséges időjárási viszonyok tovább súlyosbítottak, a napjainkban tapasztalható gazdasági válság pedig még inkább megnehezítheti megoldásukat.A megújítható energiaforrások szerepének növelésében katalizátorszerepet betöltő Európai Unió már a 80-as évek elején megoldást keresett a túltermelés következtében felhalmozódott szántóföldi termékek felhasználására.

Future of Tropical Species on a Warmer Planet

Journal Articles & Books
Diciembre, 2009
África occidental

Modern global temperature and land cover and projected future temperatures suggest that tropical forest species will be particularly sensitive to global warming. Given a moderate greenhouse gas emissions scenario, fully 75% of the tropical forests present in 2000 will experience mean annual temperatures in 2100 that are greater than the highest mean annual temperature that supports closed-canopy forest today. Temperature-sensitive species might extend their ranges to cool refuges, defined here as areas where temperatures projected for 2100 match 1960s temperatures in the modern range.
