Effects of livestock grazing on soil nitrogen mineralization on Hulunber meadow steppe, China

Journal Articles & Books
Dezembro, 2016
China

Soil nitrogen (N) cycling is an important factor in terrestrial ecosystems, including grasslands. Understanding the effects of grazing on nitrogen cycling in grassland ecosystems is critical for better management and for improving knowledge of the mechanisms underlying grassland degradation and can provide basic information for sustainable development in grassland ecosystems. In this study, in situ incubation in intact soil cores was used to measure seasonal changes in soil nitrogen mineralization and nitrification in the meadow steppe of the Hulunber grasslands of northeastern China.

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

Journal Articles & Books
Dezembro, 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.

Economic benefits of climate-smart agricultural practices to smallholder farmers in the Indo-Gangetic Plains of India

Small landholders can implement a range of climatesmart agricultural (CSA) practices and technologies, in order to minimize the adverse effects of climate change and variability, but their adoption largely depends on economic benefits associated with the practices. To demonstrate the potential economic benefits of CSA practices, we conducted a study with smallholder farmers in the Indo-Gangetic Plains (IGP) of India.

Demonstrating complexity with a roleplaying simulation: investing in water in the Indrawati Subbasin, Nepal

Reports & Research
Dezembro, 2015

Rural people in Nepal and other developing nations are part of complex, social-ecological systems. Efforts to provide assistance to these people must integrate knowledge from a variety of perspectives. This report documents the use of a role-playing game, supported by an agent-based model, to demonstrate the interaction between migration, social capital and the effectiveness of water storage. The importance of these interactions was highlighted by fieldwork conducted at several sites in the Koshi River Basin.

Designing for value: Structuring voluntary certification programs to increase stakeholder acceptance

Voluntary certification programs are one type of intervention used to incentivize the commodity agricultural sector in tropical forest landscapes to reduce deforestation and improve sustainability. These programs encourage supply-chain actors to produce and source products according to agreed standards. We review the cases of the Roundtable on Sustainable Palm Oil (RSPO) voluntary certification program in Indonesia, and the Sustainable Agriculture Network (SAN) voluntary certification program for cattle in Brazil.

Controlling floods and droughts through underground storage: from concept to pilot implementation in the Ganges River Basin

Ásia Meridional

The concept of ‘Underground Taming of Floods for Irrigation’ (UTFI) is introduced as an approach for co-managing floods and droughts at the river basin scale. UTFI involves strategic recharge of aquifers upstream during periods of high flow, thereby preventing local and downstream flooding, and simultaneously providing additional groundwater for irrigation during the dry season for livelihood improvement. Three key stages in moving UTFI from the concept stage to mainstream implementation are discussed.

Climate Smart Agriculture in the African Context

Conference Papers & Reports
Novembro, 2015

Agriculture remains vital to the economy of most African countries and its development

has significant implications for food security and poverty reduction in the region. Increase

in agricultural production over the past decades has mainly been due to land area expansion,

with very little change in production techniques and limited improvement in yields.

Currently one in four people remains malnourished in Africa. CSA integrates all three dimensions of sustainable development and is aimed at (1)
