Combating Land Degradation and Desertification: The Land-Use Planning Quandary

Peer-reviewed publication
Janvier, 2019
Global

Land-use planning (LUP), an instrument of land governance, is often employed to protect land and humans against natural and human-induced hazards, strengthen the resilience of land systems, and secure their sustainability. The United Nations Convention to Combat Desertification (UNCCD) underlines the critical role of appropriate local action to address the global threat of land degradation and desertification (LDD) and calls for the use of local and regional LUP to combat LDD and achieve land degradation neutrality. The paper explores the challenges of putting this call into practice.

Unjust Burden. How smallholder farmers in Africa are adapting to climate change to improve their food security

Reports & Research
Décembre, 2017
Afrique

Over the last two decades, 200 million people across the world have been lifted out of hunger. But as climate change brings more frequent and severe weather shocks such as droughts and floods, and makes rainfall patterns less predictable, these gains are under threat, especially among Africa’s smallholder farmers. Agriculture is Africa’s biggest employer. But mean temperatures are expected to rise faster in the continent than the global average, decreasing crop yields and deepening poverty.

Effects of salinity and drought on early seedling growth and survival of Artemisia herba-alba

Journal Articles & Books
Décembre, 2015

Seedlings of Artemisia herba-alba grown in glasshouse were watered with differing salinities (0, 150, 250 or 350 mM NaCl) and watering frequencies of 3, 7, 14 or 21 days for a period of 6 weeks. At the end of the study, plant survival, dry matter yield, biomass allocation (shoot and root), leaf area, relative growth rate (RGR), net assimilation rate (NAR), specific leaf area (SLA) and leaf area ratio (LAR) were recorded. When watered with 0 mM NaCl, Artemisia herba-alba plants had similar (P> 0.9) final dry matter weight and 100% survival regardless of watering frequency.

Study of Desert Development Programme

Novembre, 1993
Inde

The desert areas of the country had remained backward in many respects due to difficult physiography varying agro-climatic conditions and distinct socio cultural features. Since the people living in these areas were facing hardships owing to geo-climatic conditions, the desert development programme was introduced as a centrally sponsored scheme in 1977-78.

Agricultural Development under a Changing Climate

Reports & Research
Policy Papers & Briefs
Août, 2009

Climate change presents a profound challenge to food security and development. Negative impacts from climate change are likely to be greatest in regions that are currently food insecure and may even be significant in those regions that have made large gains in reducing food insecurity over the past half-century. Adaptation in the agricultural sector is being given a high priority within this effort because of the inherent sensitivity of food production to climate and the strong inter-linkages that exist between climate, agriculture, and economic growth and development.

The Country Environmental Analysis (CEA) for Timor-Leste identifies environmental priorities through a systematic review of environmental issues in natural resources management and environmental health in the context of the country's economic development and environmental institutions. Lack of data has been the main limitation in presenting a more rigorous analysis. Nevertheless, the report builds on the best available secondary data, presents new data on the country's wealth composition, and derives new results on the costs of water and air pollution.

The objectives of the Costing Adaptation through Local Institutions (CALI) study were (a) to identify the costs of adaptation through local institutions, and (b) to investigate which institutions help households adapt to climate variability, which efforts and costs are needed to realize the adaptation options, and how they facilitate adaptation to climate variability. The study was carried out in Ethiopia, Mali, and Yemen. This report discusses the results for Yemen.

Climate Risk and Financial Institutions

Décembre, 2011

This report analyzes in some detail the risks to project finance and the performance of real-sector investments. Options, futures, derivatives, foreign exchange and more exotic instruments are not specifically addressed. The objectives of institutional investors, such as pension funds, include creation of sustained revenues over a long period of time. Clearly, given this long-term perspective, institutional investors need to be particularly aware of growing risks to their investments in climatically sensitive sectors or regions.

This country note for Armenia is part of a series of country briefs that summarize information relevant to climate change and agriculture for three pilot countries in the Southern Caucasus Region, with a particular focus on climate and crop projections, adaptation options, policy development and institutional involvement. The note series has been developed to provide a baseline of knowledge on climate change and agriculture for the countries participating in the regional program on reducing vulnerability to climate change in Southern Caucasus Agricultural systems.

Sustainable Land Management for Mitigation of and Adaptation to Climate Change

Training Resources & Tools
Juin, 2010

The climate change (CC) caused by increase in atmospheric concentration of CO2 and other Greenhouse Gases (GHGs), can be addressed through adaptation and mitigation strategies. Adaptation consists of strategies which minimize vulnerability to CC. The objective is to increase resilience of the ecosystems and communities through adoption of specific sustainable land management (SLM) techniques that have adaptive benefits. On the other hand, the goal of mitigation strategies is to enhance soil and vegetation (land) sinks for absorbing atmospheric CO2 and to minimize net emissions.

Community-based Adaptation

Juin, 2010

The Development Marketplace 2009 focused on adaptation to climate change. This paper identifies lessons from the Marketplace and assesses their implications for adaptation support. The findings are based on: statistical tabulation of all proposals; in-depth qualitative and quantitative analysis of the 346 semi-finalists; and interviews with finalists and assessors. Proposals were fuelled by deep concerns that ongoing climate change and its impacts undermine development and exacerbate poverty, migration and food insecurity.

BioCarbon Fund Experience

Décembre, 2011

Carbon finance recognizes the contribution of projects to mitigating climate change. To be able to access carbon finance, projects can certify their emission reductions under a variety of standards, one of which is the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change (UNFCCC). Project developers can sell their carbon credits either in the voluntary or the regulated market.
