Displaying 1366 - 1370 of 1605empirical framework for scaling-out of water system innovations: Lessons from diffusion of water system innovations in the Makanya catchment in Northern Tanzania
Scaling-out of water system innovations such as soil and water conservation is important for increased and sustainable agricultural production. A wealth of upgraded soil and water conservation technologies such as terraces has not been widely adopted in places vulnerable to land degradation and agricultural water stress. Much focus should be on rethinking approaches for scaling-out of well-proved innovations rather than on generation of new technologies. This paper presents an empirical framework for scaling-out water system innovations at catchment level.
Creating a ‘Conservation with Chinese Characteristics’
As China becomes increasingly influential in international affairs, it is important to understand the unique characteristics of Chinese environmental values and policy processes. This is especially true given the rate and scale of China’s environmental impacts on natural ecosystems from local to international levels. Currently, however, Chinese conservation values, policies and practices are not well-integrated.
Quantifying the effect of historical soil management on soil erosion rates in Mediterranean olive orchards
Olive orchards are an important agro-ecosystem in the Mediterranean. Soil erosion is a widely recognized threat to their sustainability. However, the variability of short-term soil erosion measurements and the limited understanding of driving processes result in a considerable uncertainty over the long-term effects of soil erosion. This study aims at measuring and modelling soil erosion rates in olive orchards over a 250-year period, and relating these to changes in management practices and yield, as documented from historical sources.
Surprisingly small increase of the sedimentation rate in the floodplain of Morava River in the Strážnice area, Czech Republic, in the last 1300years
Sediment profiles from the floodplain of Morava River in the Czech Republic have been collected from exposed river banks (4–6m long sections) and cores (2–4m deep) and investigated using a set of geochemical proxies validated by granulometry and conventional geochemical analysis, outlined in our previous paper. The work was conducted to evaluate the increase in sedimentation rate during Medieval and modern time periods.
Informal settlements’ needs and environmental conservation in Mexico City: An unsolved challenge for land-use policy
The aim of this article is to analyze the effectiveness of land-use policy in Mexico City in controlling the expansion of informal human settlements in peri-urban zones of high ecological value. It is argued that Mexico City's land-use policy has been reactive and internally inconsistent, failing to take informal settlements into account, has not offered the poor access to housing with adequate services and greater security in terms of land tenure, and lacks the necessary financial resources and institutional capabilities for providing solutions to these problems.
