Aufsatz Agri-environmental evaluation of traditional and alternative corn production systems in Chiapas, Mexico 

Aguilar-Jiménez, Carlos Ernesto; Tolón-Becerra, Alfredo; Bolívar Lastra-Bravo, Xavier (Kassel University Press, 2011)
This study evaluates the effects of environmental variables on traditional and alternative agroecosystems in three Ejidos (communal lands) in the Chiapas rainforest in Mexico. The tests occurred within two seasonal agricultural cycles. In spring-summer, experiments were performed with the traditional slash, fell and burn (S-F-B) system, no-burn systems and rotating systems with Mucuna deeringiana Bort., and in the autumn-winter agricultural cycle, three no-burn systems were compared to evaluate the effect of alternative ...

Aufsatz Soil fertility and nutrient status of traditional Gayo coffee agroforestry systems in the Takengon region, Aceh Province, Indonesia 

Hanisch, Susan; Dara, Zaitun; Brinkmann, Katja; Bürkert, Andreas (Kassel University Press, 2011)
Little is known about the traditional coffee cultivation systems in Central Aceh, Indonesia, where coffee production is a major source of income for local Gayo people. Based on field observations and farmer interviews, 14 representative agroforestry coffee plantations of different age classes (60-70 years, 30-40 years, and 20 years) as well as seven adjacent grassland and native forest sites were selected for this study, and soil and coffee leaf samples collected for nutrient analysis. Significant differences in soil ...

Aufsatz Domestic policy responses to the food price crisis: The case of Bolivia 

Schüttel, Carsten; Kleinwechter, Ulrich; Ihle, Rico; Grethe, Harald (Kassel University Press, 2011)
In face of the global food crisis of 2007-2008, severe concerns arose about how developing countries would be affected by the extreme short-term fluctuations in international commodity prices. We examine the effects of the crisis on Bolivia, one of the poorest countries of the Americas. We focus on the effectiveness of the domestic policy interventions in preventing spillovers of the development of international food prices to domestic markets. Using a cointegration model, we study price interdependencies of wheat ...

Aufsatz Short-term poverty dynamics of rural households: Evidence from Central Sulawesi, Indonesia 

Edig, Xenia van; Schwarze, Stefan (Kassel University Press, 2011)
The understanding of poverty dynamics is crucial for the design of appropriate poverty reduction strategies. Taking the case of Central Sulawesi, we investigate the determinants of both chronic and transitory poverty using data from 264 randomly selected households interviewed in 2005 and 2007. Regarding the US 1$/day poverty line, the headcount index declined from 19.3% in 2005 to 18.2% in 2007. However, we observed an increasing number of people living on less than US 2$/day expressed in purchasing power parity ...

Aufsatz Ideotyping integrated aquaculture systems to balance soil nutrients 

Muendo, Patricia N.; Stoorvogel, Jetse J.; Verdegem, Marc C. J.; Mora-Vallejo, Alejandra; Verreth, Johan A. J. (Kassel University Press, 2011)
Due to growing land scarcity and lack of nutrient inputs, African farmers switched from shifting cultivation to continuous cropping and extended crop area by bringing fragile lands such as river banks and hill slopes into production. This accelerated soil fertility decline caused by erosion, harvesting and insufficient nutrient replenishment. We explored the feasibility to reduce nutrient depletion by increasing nutrient utilization efficiencies, while diversifying and increasing food production through the development ...

Aufsatz Factors influencing a conversion to organic farming in Nepalese tea farms 

Karki, Lokendra; Schleenbecker, Rosa; Hamm, Ulrich (Kassel University Press, 2011)
Organic agriculture in developing countries has increased in past decades especially due to the high demand of organic products in developed countries. The rate of conversion to organic production in Nepal, however, is observed much slower than expected. This study investigates factors that determine the conversion to organic production using Nepalese tea producers as a case study. A survey of 181 farmers was conducted in the Ilam and Panchthar district of Nepal, among which 86 were organic farmers and 95 were ...

Aufsatz Resource use pattern and agroecosystem functioning in Rawanganga micro-watershed in Garhwal Himalaya, India 

Bagwari, H. K.; Todaria, Nagendra P. (Kassel University Press, 2011)
Agro-ecological resource use pattern in a traditional hill agricultural watershed in Garhwal Himalaya was analysed along an altitudinal transect. Thirty one food crops were found, although only 0.5% agriculture land is under irrigation in the area. Fifteen different tree species within agroforestry systems were located and their density varied from 30-90 trees/ha. Grain yield, fodder from agroforest trees and crop residue were observed to be highest between 1200 and 1600 m a.s.l. Also the annual energy input- output ...

Aufsatz Evaluating partial root-zone irrigation and mulching in okra (Abelmoschus esculentus L.) under a sub-humid tropical climate 

Panigrahi, Pravukalyan; Sahu, Narendra Nath; Pradhan, Sanatan (Kassel University Press, 2011)
The field experiments were conducted to compare the alternate partial root-zone irrigation (APRI) with and without black plastic mulch (BPM) with full root-zone irrigation (FRI) in furrow-irrigated okra (Abelmoschus esculentus L. Moench) at Bhubaneswar, India. APRI means that one of the two neighbouring furrows was alternately irrigated during consecutive watering. FRI was the conventional method where every furrow was irrigated during each watering. The used irrigation levels were 25% available soil moisture depletion ...
