This study analyses the impact of intensity of tillage on wheat productivity and risk exposure using panel household-plot level data from Ethiopia. In order to control for selection bias, it estimates a flexible moment-based production function using an endogenous switching regression treatment effects model. The result shows that tillage has a complementary impact on productivity and risk exposure.

As the world`s population is constantly growing, food security will remain on the policy Agenda, particularly in Africa. At the same time, global food systems experience a new wave focusing on local foods and food sovereignty featuring high quality food products of verifiable geographical origin. This article argues that Geographical Indications (GI´s) hold the potential to help transform the Tanzanian agriculture-dependent economy through the tapping of value from unique products, attributing taste and colour to place or regional geography.

Single objective approach is most widely used whereas consideration of multiple objectives is the rule rather than an exception in many real life decision-making circumstances. This paper, therefore, investigates whether or not single and multiple criteria/objective approaches necessarily lead to differing conclusions. The central questions are could the single objective approach be a reasonable approximation for subsistence farm settings or does the multiple objectives approach has anything to add?

Using province-level yield data and daily weather data from 1980 to 2012, we investigated the responses of early rice, middle-season rice, and late rice yields to weather variations in China. In contrast to prior studies that found negative impacts of elevated daily minimum temperature (Tmin) on rice yield in tropical and subtropical regions, we discovered that rising Tmin increased early and late rice yields in China, with the positive temperature effects varying by rice-growth stage.

Using a mathematical programming model, we estimate the economic potential of biomass supply from crop residues in China at various exogenously-given biomass prices and identify the areas that are likely to produce crop residues. Our analysis indicates that China can potentially produce about 174.4–248.6 million dry metric tons of crop residues per year when biomass prices are larger than $100 per metric ton. Rice straw is expected to account for about 47% of total residue production across the different biomass prices and residue production scenarios that we considered.

Abstract: According to advocates, eco-certification is a win–win solution to the problem of environmental degradation caused by developing country agriculture, improving both the environmental and the economic performance of farmers. However, these notional benefits can be undercut by the tendency of relatively wealthy farmers already meeting eco-certification standards to disproportionately participate.

Strengthening the planning of hydrological resources to optimize the use ofwater in agriculture is a key adaptation measure of the Chilean agricultural sector to cope with future climate change. To address this challenge, decision-makers call for tools capable of representing farmers’ behaviours under the likely stresses generated by future climate conditions.
