The article describes the land use system transition dynamics in selected states in India and discusses its underlying biodiversity impacts and economic driving forces. The concept of system transition is described as a continuum between forests and highly intensive agriculture via different grades of intensification where profit differential is identified as the system transition pressure. In order to operationalise the concept, the article develops land use suitability, input use intensity and farming system diversity indices which are calculated for different agricultural cropping systems in the selected states of India. The results show the apparent decline in land use suitability, reduction in farming system diversity, increase of cultivation intensity, reflecting a reduction in planned and associated agro-biodiversity. The results also show increasing transition pressure to shift from low intensive and high diverse systems to high intensive low diverse systems that represent increasing opportunity cost of conservation of the former systems. A set of policy measures to deflate the transition pressure that can at least retain a threshold of traditional high diversity systems are briefly discussed. The study also outlines further research directions. (C) 2015 Elsevier Ltd. All rights reserved.

Can Enhancing Efficiency Promote the Economic Viability of Smallholder Farmers? A Case of Sierra Leone

Silvia Saravia-Matus, T. S. Amjath-Babu, Sreejith Aravindakshan, Stefan Sieber, Jimmy A. Saravia, Sergio Gomez y Paloma

Summary: This study found that in a food insecure environment, the economic viability of smallholder farms is positively correlated with technical efficiency, but technical efficiency is not the sole determining factor. Smallholders may need to sacrifice technical efficiency to breach reproductive thresholds in a crop diversification strategy. Therefore, a dual policy approach is needed that focuses not only on increasing production efficiency for self-sufficiency but also on encouraging market-oriented economic crop production.

Summary: This study investigates the potential of Climate Information Services (CIS) in the Lower Ganges Delta of Bangladesh through a participatory CIS development case study. Farmers in the experimental group, who were exposed to and trained in CIS, showed a higher willingness to pay for CIS compared to the control group. Farmers' willingness to pay was influenced by CIS cost and prior exposure and training, indicating a huge market potential for CIS in Bangladesh.

Developing a framework for an early warning system of seasonal temperature and rainfall tailored to aquaculture in Bangladesh

Summary: The occurrence of high temperature and heavy rain events during the monsoon season in Bangladesh poses a major climate risk to aquaculture production. However, developing operational tools for seasonal forecasting remains challenging. This study presents a seasonal forecasting approach that uses linear models and meteorological data to predict the number of warm days and heavy rain days in two locations in Bangladesh. The results show that the models have higher predictive skill for warm days than heavy rain days, and for one location (Sylhet) than another (Khulna). Among the evaluated models, CanSIPSv2 and GFDL-SPEAR exhibit the best performance.

Summary: Sustainable agricultural practices are increasingly important for global and national environmental policies and economy. This study compared the sustainability of grape production under integrated and organic management using multiple indicators. The results showed that organic management was more beneficial for most environmental aspects of the agroecosystem compared to integrated management, without affecting grape yield.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
